    - Reading Config from custom location in .NET 2.0 My company has recently purchased a software product that spans several technologies (ASP, COM, VB 6.0, .net 1.1, .net 2.0). We are trying to standardize the software over to one technology (.net 2.0). Part of this is to locate general settings (such as database connection strings etc...) into one central location. I was able to do this for the asp.net 1.1 Web Site, Web Services and console apps by setting the "file" attribute of the <appSettings> section of the relevant Config file:- E.G <?xml version="1.0" encoding="utf-8" ?> <configuration> <appSettings file="D:\Mydirectory\test.config" /> </configuration> I have created a custom class in .NET 2.0 that reads data from my custom config file, reading from the file such as this:- Return System.Configuration.ConfigurationManager.AppSettings["DatabaseConnString"].ToString(); However the problem lies when trying to use this code via COM+ so as the ASP portion of the software can get its configuration details from the same place. As COM+ executes in it own container (I think under dllhost.exe??) then using the above code to read a setting is obviosly not going to work as there is no way to set the following :- <appSettings file="D:\Mydirectory\test.config" /> What I was hoping I could do was in my custom class that gives out configuration details, is to specify a path to where the configuration data is stored (E.G D:\Mydirectory\test.config) and load that configuration file into memory and read from it. Does anyone know how to specify the location of a .config file and load it into an object to parse it for configuration settings??? Or perhaps someone knows of a way by using .NET 2.0 technologies (such as property settings) that configuration type data can easily be read from ASP via COM+. Many thanks in Advance.

    - Issue in passing username and password credentials Hi, I am facing a problem in posting Web request with username and password credentials. I am working on migrating Java client application to .Net which will send request to Java servlet. Java Client application code: HttpClient httpclient; httpclient = new HttpClient(); UsernamePasswordCredentials usernamepasswordcredentials = new UsernamePasswordCredentials(s, s1); httpclient.getState().setAuthenticationPreemptive(true); httpclient.getState().setCredentials(null, null, usernamepasswordcredentials); Object obj = null; I want info on .Net equivalent to Java's UsernamePasswordCredentials class . This UsernamePasswordCredentials is different from .net's NetworkCredential. I tried below code itz not working. Please guide me on this issue. Thanks Santhosh public static string HttpWebServiceRequest(string url, string userName, string password, string xmlContent, string domain, int timeoutMS, int reqtype) { try { System.Net.ServicePointManager.CertificatePolicy = new TrustAllCertificatePolicy(); HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url); request.Method = "POST"; request.Timeout = timeoutMS; request.ContentType = "text/xml"; request.KeepAlive = true; request.ContentLength = xmlContent.Length; request.ProtocolVersion = HttpVersion.Version10; if((userName != "") && (password != "")) // I need to use some different class here. request.Credentials = new NetworkCredential(userName, password, domain); using (StreamWriter sw = new StreamWriter(request.GetRequestStream())) { sw.Write(xmlContent); } using (StreamReader sr = new StreamReader(request.GetResponse().GetResponseStream())) { return sr.ReadToEnd(); } } catch (Exception e) { throw; } } Tag: How can I use C++ Lib file into dot net Tag: 125821

    - Go C# .NET for the larger applications? Is there a list somewhere of companies or other software applications initiatives that are using .NET for implementation? (i.e. software running on the CLR) I'm especially thinking of the larger applications. E.g. something which maintains a large database or extensive GUI, etc. I just thought of this example: would it be feasible to implement a large development environment like Visual Studio in .NET? I'm sure it can be done, but what can be said for it, or against it? Maybe the question was asked before many times, but it's 2007 now and I need to ask again (or point me to some urls please): When I have ideas for a new software I want to develop, : Why would I choose to implement in .NET? (probably using C#) Pro's, cons, compared to writing a native code application? I know most of the technical advantages, but put it this way: How would you explain the choice to target the .NET platform to the management of a/your company? (This latter question would be irrespective of application size). Tag: How can I use C++ Lib file into dot net Tag: 125820

    - Generics and constructors. There is something that I don't understand about .NET Generics. I have code like the following: public class A { private string _paramOne; private string _paramTwo; public A(string paramOne, string paramTwo) { _paramOne = paramOne; _paramTwo = paramTwo; } } public class GenericA<T> where T : new() { public GenericA(string paramOne, string paramTwo) { new T(paramOne, paramTwo); } } static void Main(string[] args) { GenericA<A> instance = new GenericA<A>("paramOne", "paramTwo"); } In trying to get the strings to the type specified by the generic type parameter I get numerous errors mainly focusing on the fact that I either must define a parameterless construtor or I cannot use parameters in a constructor. So my question is two fold. How do I get the arguments on the GenericA<A> constructor to the A class? And, when and how is the type A instantiated and constructed. Thank you.

    - Custom Attributes and properties ordering Is there any common practice for ordering of an object's properties? Think this as an example: You have a List<OfClass> and you provide an instance of this list as Datasource to a grid. Is there any custom attribute that IF it will be taken into account, the grid's columns will reflect a "custom" ordering or the class's properties? If one provides an instance of a List<OfClass> to a datagrid, what will the order of the columns be? Tag: How can I use C++ Lib file into dot net Tag: 125811

    - .NET 3.0 support for Windows 2000? Does anyone know if there is any planned support for .NET 3.0 on windows 2000? It seems like a major miscalculation not to support win2K - there is still a huge install base, and it will be a while before there are enough 3.0 applications to make it compelling to switch to a later OS - in the meantime adoption is likely to be slower because of the lack of support. We are in the process of determining an archiceture for a major new project, and it looks like we will have to use WSE 3.0 instead of WCF (and .NET 3.0), which is VERY frustrating. Another question - any idea why it is is not supported? Tag: How can I use C++ Lib file into dot net Tag: 125795

    - certificate revoked problem while installing dotnet 2.0 framework Hi, I downloaded the dotnet 2 framework distributable, and tried to install it. After the unpacking phase the installer starts and then exit with an error. in the log file I found the following error : C:\DOCUME~1\Yinon\LOCALS~1\Temp\IXP000.TMP\netfx.msi could not be opened. Verify that the package exists and that you can access it. I tried to run the netfx.msi by myself (open the installer and before it ended copy the file to different directory) and then I get some error about software restriction policy. I looked again in the log file and found the following errors: SOFTWARE RESTRICTION POLICY: C:\DOCUME~1\Yinon\LOCALS~1\Temp\Copy of IXP000.TMP\netfx.msi was disallowed because a required certificate in its digital signature has been revoked by its issuer (status = 0x800B010C).

    - ExecutablePath, StartupPath and special caracters Hi all, I faced a small problem and was wondering the reason (if any) for this. You can do the following test, quite easy. Just create a small app, displaying values of : Application.StartupPath and Application.ExecutablePath Now when running this app from a directory containing a special caracter like for example "c:\myÃ©app" then StartupPath works correctly where ExecutablePath returns a strange special caracter instead, something like ï¿½ so "c:\myï¿½app"...

    - How to make global data thread safe ? Please Help... Hi friends, I seem to be stuck in a peculiar problem. I have a public static class with public static members (different array lists). The members are thus global in nature and accessible across the namespace. I have a worker function which is called asynchronously (so that there are several instances running per second) and which reads the different global members at different points of execution (not the entire set at any one point). I have a writer function which is used to set the global members and this is the only one in the application writing to these variables. It will write the entire set of globals when given control through a GUI event. I need a mechanism where if one instance of worker function is accessing any of the global members and the writer function is called, all instances of worker function (which I assume would be different threads) should complete their read operation and wait before next read (of another global member) until the writer function is finished updating all the globals. This must also mean that the writer function wait till all instances of read operation are complete and then go ahead to update the variables. I have gone through Lock, Mutex, Semaphore but feel quite confused about the type of model that I should implement. Please help me.

    - ClickOnce Error: The application is improperly formatted I've spent the last day trying to figure out what's wrong with my ClickOnce deployment. I've found this question asked a lot in forums, but no helpful answers... I've created a WinForm application through VS2005 on my WinXP SP2 machine. I then published it to a network drive (on our Novell network). The deployment worked well and I was able to install it on my machine and several others. There are some machines, however, where it won't install. I keep getting the error "The application is improperly formatted" error whenver we click on Setup.exe. I'll post the full error log below. I've successfully installed on WinXP SP1 and SP2 machines. I've not been able to successfully install on WinXP SP1 and SP2, as well as Win2000 machines, so I can't narrow it down to an OS. I've run windowsupdate on several of the machines and still no joy. I've tried (and failed with) the following: - Publishing to my local machine, then copying the deployment up to the network drive - Copying the deployment files off the network to the machine with the problem - Unclicking "Sign the ClickOnce manifests" in the Project-Properties-Signing page, then redeploying - Creating a new test certificate through the Project-Properties-Signing page, then redeploying Other info: - I've got the app set up as a "Full trust application" for the "ClickOnce Security Settings" - I have not manually modified the manifests after they were created Any help would be very much appreciated!

    - Global data concurrent access ? Hi friends, I have some global structure in my application. The data within this is read by some reader threads. There are about 10 new threads created per second. Threads do some processing and die. All threads process based on data read from the global structure. This global structure is populated from a set of files at application startup, which can be modified at run-time. There is also the option to apply the modified files at run-time. At the time the modified files are read into the application, I need to block access to this global structure from the 'reader' threads. Threads do not modify this structure. What is the best/efficient way to achieve this task - lock / mutex / wait - and how can this be done ? Any ideas are welcome.

    - Custom Config Section: How to get a TimeSpan from an attribute value? Hello In my custom configuration section, I'd like to specify an interval attribute which specifies an interval in milliseconds. I think it would be very comfortable to get this value directly as a TimeSpan. That's what I tryied: [ConfigurationProperty("interval", IsRequired = true)] public TimeSpan Interval { get { return (TimeSpan)this["interval"]; } set { this["interval"] = value; } } I really got a TimeSpan, but unfortunately the value in the attribute is automatically converted to days. Then I tried this: [ConfigurationProperty("interval", IsRequired = true)] public TimeSpan Interval { get { return TimeSpan.FromMilliseconds((double)this["interval"]); } set { this["interval"] = value; } } But this did not work at all.

    - about System.IO.FileLoadException Exception from HRESULT: 0x800736B1 (Could not load file or assembly ...) I have a program which run fine on my computer and on some client computer. However, recently, it started to crash at launch time with a mysterious error as in the title. After a bit of investigation it is probably a missing native DLL dependency in a Managed C++ library.

    - Editing a DataGridView bound to a DataView I have an application that displays data in a DataGridView. The data is in a DataView that is sorted and at times filtered. One of the columns I have in the dataview is a boolean field called "selected". Typically the DataView will either be sorted or filtered by this column. However when the user toggles the row value for this column (and others as well) in the DataGridView and ends the edit the data in the dataview changes, causing the filter or sort to reapply. This gets aggravating when the user goes to select what "was" the row below or above and suddenly it is a second row away. If a filter is applied the row they just modified may even be filtered out now and longer visible. It causes multiple data entry mistakes as well. I would like to be able to allow the user to modify the data in the grid while displaying their chosen dataview as there are several records to work with. What is the proper way to handle this type of problem? How can I make the DataGridView NOT AcceptChanges on the dataset (I think this may be the way to work around the issue) but still modify the row values?

    - InstanceDescriptor problem rendering Nullable<double> constructor parameters I have a class like so: public class MyClass { public MyClass(double? x, double? y) { } } I have created a type converter for this class that converts MyClass to an InstanceDescriptor which renders a line of code like the following on a form when x and y are null: this.myComponent1.MyClassInstance = new MyClass(null, null); The designer deserialization mechanism in Visual Studio is able to correctly determine which constructor must be called on the MyClass class when entering design mode. However, if x and y are not null, and happen to have no decimal, the following line of code is rendered: this.myComponent1.MyClassInstance = new MyClass(2, 1); This causes an exception when the form is designed with an error about a constructor with Int32, Int32 signature not being found. It appears as though there is no implicit conversion (for some reason) from Int32 to Nullable<Double>. So far I have not been able to find a way to cause the InstanceDescriptor to render an explicit cast statement (double?) to ensure the constructor is called successfully. Has anyone experienced this problem before, and if so, how did you solve it? Thanks. -- Nathan Tag: How can I use C++ Lib file into dot net Tag: 125737

    - MI5 Persecution: Communications with Security Service Tribunal in 1999 Communications with Security Service Tribunal in 1999 I took some more potshots at the SS-Tribunal in the first half of 1999. The correspondence between myself and the Tribunal Secretary is detailed on this webpage. Ultimately I decided not to pursue another complaint with them, partly from Robin Ramsay's advice (and that of a solicitor I consulted), but mostly because it was rather obvious from Mr Brooks' replies that the Tribunal has no investigative means of its own and is that useless animal, a toothless watchdog. Included with this first letter was a copy of the leaflet, "Complaints about the Security Service". This tells you that the Tribunal can order "the service to end its inquiries about you; the service to destroy any records it holds about those inquiries; the quashing of a property warrant; financial compensation". Yeah, right. Look, there's a flying pig, oink-flap, oink-flap. My subsequent letter to Nick Brooks, Tribunal Secretary, dated 25 March 1999, said; Dear Mr Brooks, We spoke on the phone last week and you kindly sent a copy of the form, "Complaints about the Security Service". I have a few questions which I should like to ask you, before I undertake the task of making a formal complaint. As you know I made a complaint in February 1997, and in June of that year the tribunal made a bland and unsatisfactory statement that "no determination in your favour has been made on your complaint". During our phone conversation I expressed the view that the Tribunal was incapable of performing its functions and acts as a whitewashing body for the Security Service. My questions are as follows; (1) Has the Security Service Tribunal ever during its existence found in favour of a compaint against MI5? (2) Is the Tribunal able to disclose whether "no determination in your favour" is made because MI5 claims to have no inquiries on a subject, or whether it is made because MI5 admits to actions against a subject but claims justification? If disclosure is not possible for individual cases, then in 1997 for how many cases (out of what total) did MI5 claim justification? (3) Is the Tribunal able to investigate information such as British Airways passenger lists, given that these could conclusively prove MI5 involvement? Would the Tribunal be forced to rely on MI5 to carry out such investigations, or would it have some other means of investigating? It might look slightly ridiculous for the Tribunal to rely on MI5 to investigate their own misdeeds. When I made my previous complaint to the Tribunal in 1997 I gave very little information as to the nature of my complaint. This time I intend to give as complete information as possible; but before I do so, I would ask you to answer the questions above, to outline the "ground rules" for a Tribunal investigation and reporting of its results. Yours sincerely, Mr Brooks replied by sending me a photocopy of two pages from the 1997 Report of the Security Service Commissioner, as follows. The photocopied pages from the 1997 Report follow. In particular, the answers the report gives to my questions are; the Security Service Tribunal has NEVER found in favour of a complainant; see sections 29 and 31 of the scanned report. Nick Brooks has confirmed orally over the phone that he has no memory of the Tribunal ever finding in favour of a complainant. Secondly, the question of whether the Tribunal is able to disclose "no determination in your favour" is because MI5 claims to have no inquiries on a subject, or whether it's because MI5 admits to having inquiries but claims they are justified. The answer to this one is in section 24, which says the ambiguity is intentional; and the Tribunal will in no circumstances give an unambiguous answer of whether MI5 claims or disclaims inquiries on a subject. In section 27 of the report, SS Commissioner Lord Justice Stuart-Smith says the blanket denials "might lead some to speculate that members of the service are carrying out operations involving unlawful interference with property, such as the installation of eavesdropping equipment, without first obtaining a warrant from the Home Secretary." He goes on to try to deny this speculation. But we've heard from Peter Wright that this went on all the time in the 1960s. So why wouldn't it still be happening now? Of course it is. The Tribunal Secretary had avoided answering the question from my previous letter, of whether the Tribunal had any independent investigative capacity. So I asked him again. Dear Mr Brooks, Thank you for your letter dated 6 April enclosing an extract of the 1997 Report of the Security Service Commissioner. This answers two of the three questions asked in my letter of 25 March. The third question remains. In 1993 I travelled on a British Airways flight on which there also travelled four men, one of whom stared at me, laughed and said, "if he tries to run away we'll find him". I took this to mean that these were the men who had been pursuing me for some time in the UK. This leads me to ask again the last question in my previous letter; (3) Is the Tribunal able to investigate information such as British Airways passenger lists, given that these could conclusively prove MI5 involvement? Would the Tribunal be forced to rely on MI5 to carry out such investigations, or would it have some other means of investigating? It might look slightly ridiculous for the Tribunal to rely on MI5 to investigate their own misdeeds. I would very much hope that some means is available to the Tribunal and Commissioner to investigate possible MI5 malefaction, other than relying on MI5 themselves. When I receive an answer to this question from you, I will work to put together a more comprehensive and detailed complaint for the Tribunal's consideration. Yours sincerely, Brooks' reply was; Brooks doesn't want to give a direct reply to the question, since that would place him in a bad light. So he gives an indirect answer; the tribunal, he avoids saying, has no investigative capacity; there is no mention even of any investigative capacity provided by MI5 themselves; nobody can investigate anything, all the Tribunal can do is ask MI5, and they, in their "Alice in Wonderland" world, can redefine the truth as it pleases them, and dissemble, and lie. Before deciding not to put another formal complaint before the Tribunal, I asked Robin Ramsay, editor of Lobster magazine, what he thought of the idea of making a complaint to the Tribunal. He replied; RESPONSE Yes it is a waste of time. They will do nothing. In a further email he elaborated; As for quoting me on the Security Service Tribunal - if you think my comments would mean anything, feel free. The problem people have is this: they almost have to go through the motions of going to the Tribunal for if they don't they will always be asked, 'Why didn't you go the proper authorities?' (This is one of the chief functions of 'the proper authorities'.) Robin Ramsay So the sum of the various parts of this story is; DON'T GO TO THE TRIBUNAL. If you do, then MI5 will open a file on you (if you don't have one already). Don't do as I did, do as I say. If you feel a really deep-seated urge to complain, do so first under an invented name, which will make you understand just how useless the Tribunal is, how little information they provide, and how unpleasant it is to know that you have given MI5 a reason to officially open a file on you in their Registry. 716 Tag: How can I use C++ Lib file into dot net Tag: 125730

    - System.OutOfMemoryException with .NET 2.0 but NOT .NET 1.1 Hello, We use a third party reporting system (Actuate) which provides soap services via WSDL. My web application was initially built in Visual Studio 2003 using .NET 1.1. I was able to download huge files, i.e., over 100MB with no problems. Actuate also has a utility (c# win app) that has no issues with a .net 1.1 version. Our dev house has upgraded to VS2005 and we have recompiled everything which is now under .NET 2.0. Now my web app may be able to download a file over 100MB once and then report a System.OutOfMemoryException. This also occurs in my DLLs and the Actuate utility that were all compiled with VS2005. Is there a bug in the .NET Framework 2.0 somewhere in the memory allocation or stream allocation process? The exception thread below shows at what point the process is dying. Is there anyone that has any ideas around this? Thanks in advance. Again, none of the code has been changed, we just recompiled in vs2005 and now are under .net 2.0 rather than 1.1. That's the only change. ***************************************************** at System.String.GetStringForStringBuilder(String value, Int32 startIndex, Int32 length, Int32 capacity) at System.Text.StringBuilder.set_Capacity(Int32 value) at System.Xml.BufferBuilder.ToString() at System.Xml.XmlTextReaderImpl.ParseText() at System.Xml.XmlTextReaderImpl.ParseElementContent() at System.Xml.XmlTextReaderImpl.Read() at System.Xml.XmlTextReader.Read() at System.Xml.XmlTextReaderImpl.InitReadElementContentAsBinary() at System.Xml.XmlTextReaderImpl.ReadElementContentAsBase64(Byte[] buffer, Int32 index, Int32 count) at System.Xml.XmlTextReader.ReadElementContentAsBase64(Byte[] buffer, Int32 index, Int32 count) at System.Xml.Serialization.XmlSerializationReader.ReadByteArray(Boolean isBase64) at System.Xml.Serialization.XmlSerializationReader.ToByteArrayBase64(Boolean isNull) at Microsoft.Xml.Serialization.GeneratedAssembly.XmlSerializationReaderActuateAPI.Read14_Attachment(Boolean isNullable, Boolean checkType) at Microsoft.Xml.Serialization.GeneratedAssembly.XmlSerializationReaderActuateAPI.Read167_DownloadFileResponse(Boolean isNullable, Boolean checkType) at Microsoft.Xml.Serialization.GeneratedAssembly.XmlSerializationReaderActuateAPI.Read517_downloadFileResponse() at Microsoft.Xml.Serialization.GeneratedAssembly.ArrayOfObjectSerializer165.Deserialize(XmlSerializationReader reader) at System.Xml.Serialization.XmlSerializer.Deserialize(XmlReader xmlReader, String encodingStyle, XmlDeserializationEvents events) at System.Xml.Serialization.XmlSerializer.Deserialize(XmlReader xmlReader, String encodingStyle) at System.Web.Services.Protocols.SoapHttpClientProtocol.ReadResponse(SoapClientMessage message, WebResponse response, Stream responseStream, Boolean asyncCall) at System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String methodName, Object[] parameters) at ActuateAPI.downloadFile(DownloadFile DownloadFile1) at CAcApi.DownloadFile(String sFileName) Tag: How can I use C++ Lib file into dot net Tag: 125729

    - Security: ¿how to store an encryption key locally? Hi, i need to know the best practice about a security issue... For a WinForms C/S application it is required to store an encryption key locally. ¿How can store that key to be accesible only by the application but no by unauthorized users? Options: - A file: The key should be encripted, but again we have a key to store. - Hard coded in the application: The problem here is possible decompilation (even with obfuscation you can reach the key) - ¿Using an OS service or another external entity?

    - Microsoft Internet Explorer Displays a Blank Page While It Uses HTTP 1.1 on IIS6 Hi everybody Well here is my problem Three weeks ago I have installed my ASP.NET 1.1 application on a Clustered web server. In order to reduce the size of my pages (cause of remote points of the company) I have enabled HTTP 1.1 Compression on my IIS 6.0 Since then I have started to have some bizarre behaviours in Internet Explorer. I have noticed that after some post backs the internet explored display a blank page. But the curious is that when I'm viewing the source of the web page the HTML code is all there. If I copy it and paste it on an HTML file I can view it on Explorer without any problem. The other strange thing is that then I'm viewing the page from the local LAN 100Mbits I don't have any problem. But when I'm viewing from an other point that it is connected with a leased line 512kbps I'm starting to have the problem and not all the time. I have checked the rooters for black hole and they came up clean. Have anyone any idea why this may happen?? Also keep in mind the problem occurs in windows XP with and without the latest service pack, and also in Windows 2003 R2 with all the hot fixes installed. And sorry for cross posting but I don't know where to look Is it IIS6 bug or IE bug??? Thank you for your time And please HELP!!!!!! Dim Tag: How can I use C++ Lib file into dot net Tag: 125715

    - MI5 Persecution: Eye Say, and Lord Gnome Answers Eye Say, and Lord Gnome Answers My interactions with Private Eye started in May 1995, shortly after I'd started bleating on usenet. I tried to get the Eye interested in my case, as I thought they more than anyone have their finger on the pulse, and would surely already know something about my case. In my first email to them, entitled "pas de bouteille?" (wot no bottle?), I asked if they had the nerve to publish what was known to many thousands of people. Their email flunky answered; Date: Thu, 11 May 95 13:40 BST-1 From: strobes@cix.compulink.co.uk (Private Eye) Subject: Re: pas de bouteille? In-Reply-To: <199505102232.SAA19988@freenet.carleton.ca> Bottle? Dunno really - but I've passed your mail on to the Ed for his consideration.

Thanks for the email. Unfortunately, I can't say whether or not the Eye will do anything with this... I'm only the messenger. As the only computer-literate peron in the Gnome organisation, I get to read all the email and then pass it on to the Editor. Sorry -- not very helpful, I know. Steve Mann (strobes) The following year I gave PE another little prod, which yielded the following; Date: Tue, 13 Feb 96 11:38 GMT From: strobes@cix.compulink.co.uk (Private Eye Magazine) Subject: Re: Previous communication In-Reply-To: <199602102320.SAA26182@[snip]> Sorry not to reply sooner... we've been swamped with email and I have very little time to answer it. However, the editor sees all the email received here and I'm afraid he hasn't expressed an interest in your story so I can only assume that he feels it isn't for us. Sorry. strobes Given that I couldn't provide the evidence to persuade the Eye of the credibility of my claims, I did the next best thing, which was to take out classified adverts in their "Eye Say" and "Eye Tech" columns. My motivation for doing so is obvious; the Eye is read both by many thousands of ordinary folk, but also makes its way into the homes and consciousness of the UK's political and media elite. It is also a known favourite with "Five". What better way of taking the fight to the enemy? The first small ad appeared on 10 Jan 1997 in issue 915 in "Eye Say". It ran in that column on 24/1/97 and 7/2/97. On 21/2/97 it ran in "Eye Tech", and on 7/3/97 and 21/3/97 again in "Eye Say". I then changed the ad's wording to read "BBC Newsreaders Conspiracy", and the new wording ran in "Eye Say" from 4/4/97 issue 921, 18/4/97 to 2/5/97. The word "xenophobic" in the first advert had been intended to convey the sense of exclusion through the bigotry of my enemies, both on the basis of race and mental condition, but it seemed a bit too non-specific. "BBC Newscasters Conspiracy" was a little more immediate, although readers had to actually wade through the website to find out what it was that the newscasters were conspiring to do. My next effort tried to spice up the text. "MI5/BBC Conspiracy" ran for six issues in "Eye Say", from 5/9/97 issue 931 until 31/10/97. I suppose there is something a little sad about somebody who knows he has mental illness, placing adverts about a conspiracy in which MI5's watchers enable BBC newscasters to personally and directly communicate with him while reading the news. It is pretty sad, but unfortunately it is also true, both in the objective reality we all inhabit, as well as in my own mind. There followed a hiatus of about a year until I resumed advertising on 2 October 1998. I paid over £200 for six months advertising of the new improved text "MI5 Persecution, BBC Newscasters Spying on my Home". This text ran from issue 960 until issue 972 (19 March 1999) in "Eye Say". Private Eye's editor Ian Hislop denies knowing anything about my case, as the following email illustrates. Date: Tue, 3 Nov 1998 14:10 +0000 (GMT Standard Time) From: strobes@private-eye.co.uk (Private Eye) Subject: Re: PLEASE ANSWER - THANK YOU CC: strobes@private-eye.co.uk Reply-To: strobes@private-eye.co.uk Sorry to take so long to answer. As soon as the editor returned from holiday Steve went away. Steve is still away and so I am answering your letter. I have asked the editor and he knows nothing about any conspiracy between M15 and the BBC. Hope this helps.

    - MI5 Persecution: Counter-surveillance sweep by Nationwide Investigations Group Counter-surveillance sweep by Nationwide Investigations Group In July 1994 the private detective agency Nationwide Investigations Group conducted an electronic counter-surveillance sweep of my parents' home in London. They checked for radio transmitter devices, and tested the telephone line for attached bugs. They found nothing. I am afraid that I was unsurprised at their not finding any evidence of covert surveillance. It had been made very clear to me, particularly during 1990-92, that audio, and almost certainly video, surveillance of my parents' home was taking place. But this would not have been made quite so obvious unless the persecutors were confident of their apparatus being undetectable using the technology the police, or a private agency like Nationwide, would be using. I don't know very much about the surveillance technology that has been used against me, but I understand that devices can be built which switch off on receiving a coded command, and may switch on again after a counter- surveillance sweep has completed; that devices may rapidly alter the frequency of transmission, "frequency-hopping" devices which presumably cannot be detected in a sequential scan of the sort employed by Nationwide; and of course "probe" microphones can be inserted "through-the-wall", although I hesitate to believe our neighbours would permit this. We paid Nationwide £411.25 (including VAT) for the surveillance sweep, which took them about an hour and a half to complete, using a "Professional 5000 multi-scanner, CCL UHF scanner and Guideline telephone tap detector." As I said above, I don't know very much about these things, so I can't comment on the capabilities or otherwise of this equipment. But clearly the "watchers" are using technology which in 1994 was beyond the detection capabilities of a good private detective agency. 716 Tag: How can I use C++ Lib file into dot net Tag: 125703

Will that version upgrade require a CLR version change, or will it still use the same CLR 2.0? (Please correct me if my terminology is off.) I know that C# will change (of course), but what I'm most curious about is will the Reflection API (Type, MemberInfo et al) change with it, or will that remain the same?

Hi,
It appears that you dont want to convert your .lib file into DLL and then
use DLLImport.Then Its a better plan to write a wrapper (in Managed C++, of
course) for your unmanaged class as the following Link shows with a simple
example:
