    - XmlSerializer without namespaces? Hi, I'm using XmlSerializer objects to - surprise - serialize objects to xml. My problem is that it includes the xml namespace references xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" for every single object which 1) isn't necessary in this case and 2) makes the output xml more difficult to read. My question is: Is there a way to avoid that? Thanks! Jens Tag: EnterpriseService deploy Tag: 126949

    - How to Create WinForms client and ClassLib server as one assembly? I'd like to break up my aplication into a WinForm executable, plus a class library containing application utility functions. But I don't want any client other than my own application to have access to my application library. Isn't this the point of an 'assembly'? So how can I generate these two artifacts as belonging to the same assembly? Is this possible with Visual Studio 2005? Thanks! - Joe Geretz - Tag: EnterpriseService deploy Tag: 126941

    - Windows XP and HP all in 1 printer problems I just bought a 7310 HP all in one and the software didn't install all the way and the computer is not communicating with the printer for the scan and fax modes but will communicate to print. The process of installation stops at the window "waiting for device setup to finish". I had the same problem with my other HP printer but learned to live with it. Thought a new one would solve the problem. Also, when I click on the "add hardware" Icon the message says that you can't install another device at this time because it's already installing one---interesting. Am running windows XP, have a Sony computer which is 1 1/2 yrs old. Of course I've reinstalled, checked the connections etc. all the usual things. Do the HP all in ones just not work very well with XP maybe and maybe I should try another brand. I appreciate any help. Tag: EnterpriseService deploy Tag: 126926

    - String to byte[] reloaded Hi I need an efficient method to convert a string object to it's byte[] equivalent. I know there are LOTS of methods, but they lack in efficiency. All methods allocate new memory to create the byte[] array. Of course, when memory allocation occurs, then naturally extra processing power is needed. To more explicit, MFC introduced a super-efficient method of dealing with this situation. As far as I remember (I switched from MFC to .NET few years ago), MFC's CString class has a method with the following signature: byte[] GetBuffer() This method "blocks" the CString instance until ReleaseBuffer() method is called. Again, maybe the method names are not quite as I remember, but the important thing is the principle. The marvelous result is that you may freely iterate through the byte[] array returned by GetBuffer() method and even modify it (with respect to some limits, of course), and all this, without allocating new memory. My question is: using MemoryStream class will do the job for me? I mean, there is a method called GetBuffer(), but will it allocate new memory or not, as it is not stated in MS documentation.

    - DataGridViewCheckBoxColumn null/default value Hi, I'm using a DataGridView with some checkboxes (DataGridViewCheckBoxColumn). It seems that the check box is initialized to null. I set the TrueValue, FalseValue, and IndeterminateValue to the appropriate values (true/false). But I haven't found any property that sets the null value to false. As a result, I always get NULL if no action was done on the checkbox. I need to do the following- 1. How can I make the NULL value of the DataGridViewCheckBoxColumn to indicate false. 2. How can I set the default value of the checkbox - i.e. when the grid is loaded with the checkbox, it should be checked. Any pointers in this direction would really be appreciated! Thanks, Juhi.

    - Windows DST patch causes DateTime.IsDaylightSavingTime() to be incorrect for dates in past years An interesting problem has arisen concerning the new Windows DST patches. The rules seem to apply without regard to year. For example, run the following C# code (assume you're running in the US Eastern time zone): DateTime d = new DateTime(2006, 11, 1); Console.WriteLine(d.ToString("dd MMM yyyy hh:mm tt zzz ") + " " + d.IsDaylightSavingTime()); DateTime d2 = new DateTime(2007, 11, 1); Console.WriteLine(d2.ToString("dd MMM yyyy hh:mm tt zzz ") + " " + d2.IsDaylightSavingTime()); If the DST patch has been applied, you will get the following output: 01 Nov 2006 12:00 AM -04:00 True 01 Nov 2007 12:00 AM -04:00 True The result for 1 Nov 2006 is incorrect -- it was not DST, but it would have been had the new rules been in effect. It appears that if the DST patch is applied, then for past years there is a two week period in March/April, and a one week period in October/November when IsDaylightSavingTime() will be incorrect, since during those periods the new rules will yield incorrect results. Does anyone know if Microsoft has any guidance for handling these anomalies? Will there be another patch? Wayne Tag: EnterpriseService deploy Tag: 126910

    - Size of an object Hi, is there an easy way to know how much memory an instance of an object takes? I mean, there is the sizeof(type), but this is not what I want... the sizeof(type) returns the size of all the members of the class, but if the class contains reference types like a collection or a string, it can't tell... What I need to know is, if there is a collection of strings, with each strings taking 100kb and having 5 strings in the collection, I want to have 500kb (or approx) as a return... is there an easy, thread-safe way?

    - .NET Framework 1.1 and .NET Framework 1.1 Hotfix (KB886903)? Hello, I have a development machine (Windows XP SP2, all security updates/fixes, 20GB C partition, 60GB D partition) with Visual Studio 2003 and 2005 installed (I do dev work in both). I already have SP1 for .NET 1.1 and VS2003 installed, but I want to install the latest SP1 release for Visual Studio 2005, but it requires 6+GB of space on the C: drive. The problem is that I only have about 4GB available on my C partition, so I am trying to clean up. On my development machine , I have two items listed in my Add/Remove programs list: Microsoft .NET Framework 1.1 and Microsoft .NET Framework 1.1 Hotfix (KB886903) Each of these take up about 1 GB each. It sounds odd that in order to run the 1.1. framework (with sp1), I need 2+GB of storage. Can I remove one of these components to free up some space WITHOUT affecting the installation of 1.1 SP1? Any other ideas for making some room (I have done all the standard stuff like cleanmgr, etc.)??? I also have SQL Server 2005 installed, but all the data files are on my D partition, not the default C drive. TIA!!! Tag: EnterpriseService deploy Tag: 126893

    - Interop and Constants Problem Hi, I have built a VB.NET, VS 2005 class library that is exposed to VB6/COM clients. Everything works as expected except for the fact that Constants (Const) are NOT being exported to the VB6/COM type library; they are not visible. I have tried every trick in the book to force .NET constants to be available to VB6/COM, but to no avail. Enumerators appear correctly, but I need String (Public Const Test As String = "MyString") type constants as opposed to the numeric (Integer) type Enumerator members (Test = 5); I have no choice, I cannot use Enumerators as they only store numeric values. Is there any way to accomplish this. I basically want to avoid the VB6/COM developer from having to guess which constant value to use; or if there were to be a modification, that it would be available immediately. Can anyone please help? Regards, Giovanni Tag: EnterpriseService deploy Tag: 126868

When the user creates an instance of this WS, I want to pass parameters to the instance: localhost.WSdemographics myClass= new localhost.WSdemographics(string Username, string Password); Once the user creates this instance, then they can use the actual methods in the service: DataSet my DS = myClass.GetNames(int RecordGroup); But when I go to create the instance of 'myClass' I do not get the 2 parameters in the intellisense. It wont even build, b/c it says the class does not take parms, yet its defiend as public class WSdemographics : System.Web.Services.WebService { public WSdemographics(stringUserName,string Password) { ... } ...//WebMethods ... } I dont want to have to pass the userName and Password to every moethod in the service, just at the point its reference.

    - Wanting to read XML blob from configuration I'm probably missing something because the .NET configuration model seems pretty screwed up. Since the configuration file is an XML file it would seem to make sense, at least to me, to have the reading/writing of configuration information rely on the XmlSerializer. Instead they came up with a whole new set of configuration attributes to do, I guess, the same (or similar) thing the XmlSerialization attributes do. Why? Getting to my question at hand, I plan to use the XmlSerializer to read data from my application configuration file. I would like to be able to request a section and get back an XmlNode for that section. I will then deserialize that using the XmlSerializer. I was hoping that I could simply call ConfigurationManager.GetSection(...) passing in my section name and get back an XmlNode. However, that doesn't work. So after looking at all the derived ConfigurationSection classes it appears as if the DefaultSection class will allow me to get an XML string which represents the section. Is this true? I was hoping to get an XmlNode because I was thinking that the framework had it in that form and didn't want to have to serialize back to a string. I was also surprised that there doesn't seem to be any way to programmatically specify a configSection. I seems as if I'm stuck having to do the following: <configuration> <configSections> <section name="orderFill" type="System.Configuration.DefaultSection, System.Configuration, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"/> </configSections> ... </configuration> It's kind of ugly and if I know in the code that I want to use the DefaultSection why can't I somehow tell the framework at runtime that I want to add a new configSection removing the need to specify it in the application configuration file? -- Thanks, Nick nicknospamdu@community.nospam remove "nospam" change community. to msn.com Tag: EnterpriseService deploy Tag: 126851

    - ClickOnce and proxy 407 error Hello, In our company, we would like to use ClickOnce which seems to be a very efficient way to deploy application. So we made some small tests and we quickly found the problem of the proxy 407 Error. We looked for any solution on the internet but we only found that we have to contact the support to replace the file System.Deployment.dll on the local .Net framework to make it work. For the time being, we did not call the support hoping there is another way to bypass this problem. We also tried to configure the Localmachine.config file, but it did not work.

    - Deadlock in XmlSerializer when using RedirectStandardInput Problem I have encountered a situation where a thread (say, thread-1) blocks for 10 minutes in the XmlSerializer constructor. This occurs when another thread (say, thread-2) is blocked in a call to Console.ReadLine and the process was created using System.Diagnostics.Process with RedirectStandardInput = true. In this situation, not only does thread-1 block for 10 min in the XmlSerializer constructor, but so will hang indefinitely when creating a COM object. The problem started occuring after migrating our application to .NET v2.0. I found a forum post where some other developers have run into the exact same problem. Please see this link: http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=188895&SiteID=1 (it also includes a reproducible testcase) Background We need to run multiple instances of an console application (it runs until told to stop). Since we need to run more than one process on a single machine it did not make sense to make the application a windows service. Instead we developed a windows services that spawns these (child) application processes. Using the System.Diagnostics.Process class we can not only spawn the process, but interact with it via stdin and stdout. (Not so nice) Workarounds It appears that the XmlSerializer hangs in the call to csc.exe (you can see this child process using ProcessExplorer). I can get around this problem by sgen'ing the assembly which eliminates the need for spawning csc.exe at runtime. However, this doesn't fix the problem with creating COM objects. Another workaround i've seen (see forum post mentioned above) is to not call Console.ReadLine(). However, I need this call in order to process interactive commandline input. Also note the call to ReadLine is on an MTA thread, so there should not be any STA "pumping" issues. ------------ Is anyone aware of a decent workaround to this issue (or a fix available .NET 2.0)? I seems that this problem greatly limits the usefulness of stdin redirection. Tag: EnterpriseService deploy Tag: 126825

    - .Net runtime 2.0 error, Event id: 5000 Hi, I have made some software that uses one of the COM ports to communicate with an external device. The software is written in C# and uses the new SerialPort class in .Net 2.0. It works perfectly when I use the COM ports that are integrated in my PC. It also works if I use a COM->RS232 converter as long as I don't unplug the converter when the software is running. If I unplug the converter I get a .Net runtime 2.0 error: http://therkelsen.info/images/blandet/atrack_prob.JPG This error makes the .Net runtime environment shut down my software and it seems like there is nothing I can do about it. I can not catch the "objectDisposedException" because it is thrown inside the .Net environment and makes the environment crash. Any ideas about what I can do to stop the framework from crashing? Is this a known bug in the .Net framework? Best regards, Kim Therkelsen Tag: EnterpriseService deploy Tag: 126824

    - Very long COM initialization within .NET application I have an odd problem with a COM DLL included in my .NET application. Just a quick piece of background: - We have a scanning feature in the application. - We take the scans and convert them to PDF, saving them in a database or disk. The COM DLL in question converts the scanned image (TIFF) to PDF. However, the first time you run it, it takes a long time (about six seconds) for the component to initialize and do the conversion. After that first run, it works instantly. The very odd part about this whole thing is when you remote desktop to a machine that has the application on it. If you open up the application on that machine (via remote desktop) and proceed to scan, there is no long initialization time at all. It works instantly the first time and every time after that! And yes, we log in with the same user account whether remote desktop or physically at the machine. Any thoughts on this? We've been stuck for almost two weeks now.

    - COM Object Dropout I'm writing a front-end for an application using COM to control it through simple dialog boxes. So far - awesome. But, one question: How can I detect that the application fired-up through COM has not crashed or been closed? If I manually close the application and then continue to run my front-end, it hangs. I'd like to know how to test if the object is still valid. Thanks. Tag: EnterpriseService deploy Tag: 126821

    - MSMQ Distributed Transaction Coordinator Hi clever people, Does anyone know whether or not when using Transaction with MSMQ, does it use DTC within the Windows API (not within the Managed .Net Framework) or its own internal transaction management. The reason I ask is that I built a MSMQ distribution service that distributes messages. In develpment using Transactions like the code below I could see results of 400+ messages per second to queues locally and on the network (Workgroup mode). WHen I placed the same service onto a Windows R2 x64 Server with 16 processors I was lucky to achieve 80-100 messages per second working to only local queues. After I restarted MS DTC (after a hunch) I saw vast improvement to 300 messages per second but I expect that the server should be able to run much much faster than my development PC. Let me elaborate in code what i did. (I didnt copy paste from a IDE so may not compile if you attempt to run it) using System.Messaging; namespace MSMQ{ public class MQExample{ public MQExample() { MessageQueue queue = new MessageQueue(".\private$\myQueue"); MessageQueueTransaction qt = new MessageQueueTransaction(); qt.Begin(); queue.Send("Using MessageQueueTransaction", qt); // Does this use DTC? // This next way does not use DTC for sure queue.Send("Using internal transaction", MessageQueueTransactionType.Single); qt.Commit(); queue.Close(); } } } Any ideas, or explanations of performance issues on Windows Server 2003 x64 (and x86 too) with MSMQ with .net 2 ( and 1.1) or why I would get such poor results. I've run MQBench on the server and it can send and receive in accordence to the guidelines from MS so I suspect a .net. Any help would be much appreciated Thanks Andy Tag: EnterpriseService deploy Tag: 126813

    - generating multipart/alternative mails with system.net.mail, "double encapsulation issue" Hi, I' m currently migrating some tools from .NET1 to .NET2. in the previous version we used a component called FreeSMTP to generate and send the mails. Now we use the System.net.mail component. My problem is that although I enforce the correct encoding (iso-8859-1), the mails have scrambled characters where the special caracters are supposed to be (accented letters, scandinavian letters, german letters and so on). In short this is what I do (one of the ways, I've bee trying lots of combinations but it won't do): --------------------------------------------------------------------------------------------------------------------------------------------------- (msgObj is my MailMessage object) AlternateView htmlTextView=AlternateView.CreateAlternateViewFromString(m_Content); AlternateView plainTextView=AlternateView.CreateAlternateViewFromString(m_TextContent) ; msgObj.AlternateViews.Add(plainTextView); msgObj.AlternateViews.Add(htmlTextView); msgObj.AlternateViews[0].ContentType.MediaType = "text/plain"; msgObj.AlternateViews[1].ContentType.MediaType = "text/html"; msgObj.AlternateViews[0].TransferEncoding = System.Net.Mime.TransferEncoding.QuotedPrintable; msgObj.AlternateViews[1].TransferEncoding = System.Net.Mime.TransferEncoding.QuotedPrintable; msgObj.AlternateViews[0].ContentType.CharSet = System.Text.Encoding.GetEncoding(m_Encoding).WebName; msgObj.AlternateViews[1].ContentType.CharSet = System.Text.Encoding.GetEncoding(m_Encoding).WebName; .....then I send It --------------------------------------------------------------------------------------------------------------------------------------------------- the main difference I see when I compare the mail source generated by System.net.mail, and freeSMTP is that in freeSMTP the mail header indicates a multipart/alternative mail, with a pointer to the part boundaries. Whereas the .NET version header indicates a multipart/mixed (as if it were an attachement or a linked resource) with a pointer to a boundary where I find a description of a multipart/alternative with a pointer to the text and html boundaries. I suspect the character recognition issues we've had to be linked to this "double encapsulation" situation (I think it's also the cause of another bug, some people getting the mail content as attachments....). Juste to make it a bit clearer here are the header of the mails.. first one works ok, second is giberish: OK--------------------------------------------------------------------------------------------------------------------------------------------------- Content-Type: multipart/alternative; boundary="----=_NextPart_542ab2f3_a829_4407_989d_5e7e35647ef3" ------=_NextPart_542ab2f3_a829_4407_989d_5e7e35647ef3 Content-type: text/plain; charset=iso-8859-1 Content-Transfer-Encoding: quoted-printable ------=_NextPart_542ab2f3_a829_4407_989d_5e7e35647ef3 Content-type: text/html; charset=iso-8859-1 Content-Transfer-Encoding: quoted-printable ------=_NextPart_542ab2f3_a829_4407_989d_5e7e35647ef3-- KO--------------------------------------------------------------------------------------------------------------------------------------------------- content-type: multipart/mixed; boundary=-- boundary_0_4a9a6aff-3d62-42da-9121-da29bedc1cf6 ----boundary_0_4a9a6aff-3d62-42da-9121-da29bedc1cf6 content-type: multipart/alternative; boundary=-- boundary_1_2169a616-120b-4264-8696-050078998bf4 ----boundary_1_2169a616-120b-4264-8696-050078998bf4 content-type: text/plain; charset=iso-8859-1 content-transfer-encoding: quoted-printable ----boundary_1_2169a616-120b-4264-8696-050078998bf4 content-type: text/html; charset=iso-8859-1 content-transfer-encoding: quoted-printable ----boundary_1_2169a616-120b-4264-8696-050078998bf4-- ----boundary_0_4a9a6aff-3d62-42da-9121-da29bedc1cf6-- --------------------------------------------------------------------------------------------------------------------------------------------------- I've tried clearing the header before sending the mail, and inserting the correct header, and enforcing a generated boundaries ... doesn't work, and the mail gets double items in the header ...

    - Com Com error Command Complex Library Error! I recently installed drivers for my Canon MP C530 Printer which is an upgrade for XP. The printer was designed to work with Win 98. Since then, not only does the printer still not work but I am receiving the above ComCom Error. This can take place during any/all operations, Outlook; Word; Explorer and can happen at any time for no apparent reason. When the error appears I can only get rid of it by clicking on the "ok" button several times which then freezes all programs and I loose whatever I was doing and have to do a Control/Alt/Delete in order to get out of the freeze.

    - Changind TimeZone and notification without application restart My app reads serialized DataTable containing DateTime columns. The file = = can be moved between machines with different Time Zones.

Otherwise the DateTime columns ar= e = converted to local time, and I don't want that. If I'm in GMT + 1 and = serialize DateTime column it is written like this: 2007-01-24T00:00:00+01:00. When I deserialize it on machine B with GMT += 0 = it is converted to 2007-01-23T23:00:00+00:00. I've found way to change time zones. But I can't find a way to inform my= = app (the same that is changing time zone) that time zone has changed. An= d = altought Time Zone is changed to GMT + 1 deserializing works like in GMT= = + 0.
