    - Windows Communication & Application Instancing in DotNet Good Morning, My problem is 2 fold. First of all, I want to find out a method of detecting whether a prev. instance of an application is already running (I think I already figured this out), and if so, send a message to that already running application (I am thinking by using the WIN32 API Call of "SendMessage"). I am trying to build an application within which I could do instancing/hooking. Basically, I want to be able to build an application that would be able to detect if another instance of it is already running, and if so, communicate with that already running instance, and send a command, and shut its self down. Almost the same behavior that outlook express has... i.e. if you already have outlook express already running and you attempt to lunch the executable again... it doesn't create a new instance of outlook. I currently have a function called PrevInstance() that detects whether or not a prev. instance of the same app is already running.. My only problem now is communicating with that already running instance of my application. Public Function PrevInstance() As Boolean If UBound(Diagnostics.Process.GetProcessesByName(Diagnostics.Process.GetCurrent Process.ProcessName)) > 0 Then Return True Else Return False End If End Function -- Awah Teh DigicentriQ Technologies, LLC awaht@digicentriq.com www.digicentriq.com 877 675 4742 805 732 9421 -- Awah Teh Chief Executive Officer DigicentriQ Technologies, LLC awaht@digicentriq.com www.digicentriq.com 877 675 4742 805 732 9421 Tag: The argument type System.Data.DataSet cannot be converted into parameter type Sy Tag: 54027

    - accessing to a windows service hi all! i've created a windows service written on c#. i've added some methods into the "main" class inherited from System.ServiceProcess.ServiceBase. is there any way to get an access to them from any other .net application? when i try to add a reference using the service's exe file as a source, i get a message like "a reference to '...' could not be added. this is not valid assembly or COM component. only assemblies with extention 'dll' and COM components can be referenced.", etc. so how can i get an access to the methods and properties of my service from other .net applications? thanks. --- mr.black's here...

    - Connection delay after upgrade to .NET 1.1 When making a socket connection to a server from a client using the new .NET Framework version 1.1 in a Web Application, we are getting a severe delay in the granting of the socket connection. We did not get this using the previous version of .NET (1.0...). The delay is between 1 and several minutes long. Finally, after the delay, the socket connection is made with no abnormal messages. Then, as long as that IE remains up, we can dis-connect and re-connect as many times as we want with no delays at all. Any and all comments would be greatly appreciated.

    - Getting Started on .NET I have an experience of more than 2 yrs on VB6.0 & ASP2.0. I would like to know how do I get myself started on the .NET platform.

    - HttpWebRequest, transfer-encoding? I need to post some data to a server. As I understand it (which is not to say I do understand it) I should be able to include a "transfer-encoding:" header of say- gzip, then gzip my content before posting. Since it is a transfer-encoding, I assume any half decent web server should be able to automatically ungzip it before passing it on to whatever app needs to handle it. Is this assumption correct? If so, does .NET support gzip transfer encoding or do I need an external library, program, etc. If external is necessary, where should I look.

    - Why does Microsoft have such a hard time understanding what they say? You know there is a difference between the Microsoft .NET Framework and the Microsoft .NET Framework SDK. Besides the fact that the former is 20 some MB and the latter is some 100MB there is a difference you know. But not according to this page: http://support.microsoft.com/?scid=kb;en-us;306160 This command near the bottom: N:\dotnetframework\dotnetfx.exe /t:c:\temp /c:"msiexec.exe /i c:\temp\netfx.msi REINSTALL=ALL ReinstallMODE=vomus" has not a damn thing to do with the Microsoft .NET Framework SDK. This is a reinstallation of the Microsoft .NET Framework which is NOT the Microsoft .NET Framework SDK as the title of this article says. To me this is like the misunderstanding of Microsoft Outlook and Microsoft Outlook Express. Why does Microsoft have such a hard time understanding what they say? And finally is there a repair for the Microsoft .NET Framework SDK not to be confused with the Microsoft .NET Framework?

    - .Net Framework and Sharepoint Server I was just wondering if .Net Framework would interfere with stuff in a Sharepoint Server? Because in our IIS server, we are getting a 404 on a smart client app that we are trying to deploy. We tried 3 other IIS servers (development), and it seemed to work. It is just that one server (Release) which gives us a 404. Any Ideas? Thanks. Tag: The argument type System.Data.DataSet cannot be converted into parameter type Sy Tag: 54011

    - How do I write to a private folder? Hi all, I am trying to write a stand alone C# Console program with .NET framework. The program will create a folder in a existing folder. The existing folder is set with "Make this folder private" and "Encrypt contents to secure data". I tried LogonUser, Impersonate, AddPermission to PermissionSet but none of them work. The error is "Access to ... is denied" eventhough I run the program in the same account that I used to create the folder. I dont have any problem to create to any other folders without the private and encrypt setting. I am using Windows XP, NTFS and the existing folder is created in user profile directory. Please help.

    - JIT For those of you coding windows Application under the framework you must noticed that forms take a performance hit loading the first time. This is because of JIT, I was able to fix this behavior by using ngen.exe, but then I don't get the same optimization JIT gives me and it is a headache for installations (negen has to be called right after the installation). According to Microsoft, a function gets JIT to native code the first time it is accessed. Is it possible to tell the framework to JIT certain functions at runtime without actually calling the functions? Basically, I would like to pre-JIT some of my functions so they don't experience a performance hit the first time they are called. Is this possible?

When i try to deploy it on a machine where i didn't compile the project the addin fails to load when visual studio loads. There is an error and it proposes to uninstall the addin. When i scanned the registry while compiling or installing i remarked that the registry was modified only at compil time.

    - ICertificatePolicy question. All, I've implemented a class that inherits the ICertificatePolicy interface. I then set ServicePointManager.CertificatePolicy = this. In my CheckValidationResult(), I log server cert info and return true. Now say for example, the CN name on the server cert does not match the site name, my CheckValidationResult() function is called. After returning true, if I go to the same site- my CheckValidationResult() is not called again. I assume because I returned true, and it has cached that information. My question is can I change this behavior so it will always call my CheckValidationResult() on each new request, if there is a cert problem? I've checked ServicePointManger and ServicePoint but do not see any method that would clear, flush, reset, etc. this information. Regards Erin.

    - Regular expressions and HTML Hi I'm working on a method that will transform an HTML fragment into an XHTML fragment. I thought I'd have a go at using regular expressions in .NET, because I don't really understand the numerous regular expression classes in .NET and I thought it might be a good opportunity to learn. I want to break down the HTML into element names, attribute names, attribute values and element content. The regular expression I came up with, that successfully matches fragments such as <div contenteditable id="test">, looks like this: ^(?<precedingText>[^<>]*)((((<(?<elementName>[a-zA-Z_][a-zA-Z0-9_]*)\s*((?<=\s)(?<attributeName>[a-zA-Z_][a-zA-Z0-9_]*)((\s*=\s*""(?<attributeValue>[^""]*)""\s*)|(\s*=(?<attributeValue>[^\s"">]+)\s*)|(\s*(?!\s*=))))*\s*>))|(</(?<closingElementName>[a-zA-Z_][a-zA-Z0-9_]*)\s*>))(?<text>[^<>]*))*$ A bit complicated I know, but it works. However, now I don't know how to extract the various elementName, attributeName etc. group values in order to match them up. All seems a bit wild to me. Can anyone tell me the best way to construct a regular expression in order to produce the desired result? I suspect using constructs such as (?<elementName>....)* doesn't work so well because of the repeat, but how else could it be done?

    - How to obtain invalid file name characters Hi, How does one obtain a platform's invalid file name characters from the .NET framework? I have noticed that invalid path characters can be obtained from System.IO.Path.InvalidPathChars but this list does not include items that would be illegal for file names (for example, a colon: would be invalid in a MS Windows environment). Please note that catching an exception from Path.GetFileName() would allow me to test the validity of a file name but would not allow me to include the invalid characters in a message to the user. Many thanks. Nathan Tag: The argument type System.Data.DataSet cannot be converted into parameter type Sy Tag: 53833

    - Template Based Applications I am about to start a new project, which a template based application. It's a report generator (MS Word). The user selects a report template and fills it with the report specific information. It can't be ms word template itself. The application is much more complicated than that. Do you know of the papers/articles regarding the template based application architecture and design? Tag: The argument type System.Data.DataSet cannot be converted into parameter type Sy Tag: 53832

    - Faulty implmentation of ThreadPool.RegisterWaitForSingleObject I think I've found a problem in the framework implementation of the ThreadPool RegisterWaitForSingleObject method. Given the following C# code: static void Main(string[] args) { ManualResetEvent evt1 = new ManualResetEvent(false); ManualResetEvent evt2 = new ManualResetEvent(false); ThreadPool.RegisterWaitForSingleObject(evt1, new WaitOrTimerCallback(EventProc), "Event 1", 30000, false); ThreadPool.RegisterWaitForSingleObject(evt2, new WaitOrTimerCallback(EventProc), "Event 2", 30000, false); evt1.Set(); evt2.Set(); Thread.Sleep(20); evt2.Reset(); evt1.Reset(); } private static void EventProc(object state, bool timedOut) { Console.WriteLine(state); } I'd expect to see messages for both Event 1 and Event 2 during the time they are both set. However, only messages from Event 1 show up. According to the docs, the RegisterWaitForSingleObject method is implmented using the Win32 WaitForMultipleObjects call to monitor all of the registered objects, with the fWaitAll parameter set to false I'd assume. However in that case, the WaitForMultipleObjects call only returns at most one indicator of a signaled object even if more than one of the objects are signaled. That means that when both evt1 and evt2 are signaled in the above code, the program will only get notifications of the lowest indexed one in the WaitForMultipleObjects handle array. Obviously using manual event handles makes the problem stand out more, but this could definitely cause problems if someone expects notifications no matter how many other objects are signaled at the same time. I beleive that the implementation should be corrected, or at least have the framework documentation updated to point out this issue.

    - How can I set advanced file properties with .NET? Hi Space! Im looking for a way to set the advanced file properties (e.g. title, author, subject, etc.) on a file which is on a NTFS volume out from C#. I can only find methods to set the normal properites (attributes) (e.g. last access time, archive, etc.). Is there a way to do this in .NET? I'm glad for any hints!

    - Cannot create an object of type 'System.String[]' from its representation 'String[] Array' Hello, I am designing a .net custom control in VS.net 7.1 and my control exposes an array of strings which are supposed to be the items to show. To do this have declared a private string[ ] variable and a public property which returns it. string[] options = new string[1]; public string[] Options { get { return options; } set { options = value; } } It works fine in the disigner and I can add items to the list using the VS.net string collection editor and see the changes in real-time. But when I run the App, I recieve this error: Cannot create an object of type 'System.String[]' from its string representation 'String[] Array' for the 'Options' property. Even with other types of collections (objects, etc.), I receive this error. What should I do. Tag: The argument type System.Data.DataSet cannot be converted into parameter type Sy Tag: 53804

This is very strange indeed. It sounds like the type of message you would
get when using a web reference (which creates a "copy" of the type
definition, two completely different types as far as the runtime is
concerned).

Are you somehow loading separate versions of the framework?
