• .NET Development SMTPClient sending anonymous on UseDefaultCredentials

  When sending mail via System.Net.Mail smtpClient, I would like to take advantage of using the currently logged in user's credentials to avoid hardcoding login information. I believe this is as simple as mailClient.UseDefaultCredentials = True /* mailClient.Credentials = New System.Net.NetworkCredential("mylogin", "mypassword") */ In my case, sending e-mail is successful when using hard-coded login information as shown above. However, the process times out if I attempt to use the default credentials. Looking on the server side, I see that the client presents itself as anonymous and the server does not respond because it does not accept anonymous requests. I log into a local domain (Windows 2003 Server) wh ...Show All

• Windows Forms How do I validate an dataviewgrid and also allow canceling?

  I have a datagridview that I'm letting users enter data into. It is unbound...well it is bound to a datatable I create when the form loads. I want to validate the cells. I used cellvalidateing to check for length, if empty, etc. Seemed to work fine. Until I tried to press the cancel button on the form to close the form. I could not leave the datacell. Is there a way to cancel the validating when a certain button is pressed Is there another way I should be validating Does anyone have examples Thanks. The problem is that the cellvalidating event fires first no matter what. So the button press event doe not fire until after. I use the cancel property to say tell if the validation failed. I'm assuming there has to be another way to va ...Show All

• .NET Development Interop Thread Leak?

  Hi, I'm hoping for a few pointers for tracking down a resource leak. I developed a VB 2.0 indexing application which is using FileNet's Capture COM objects and we're occasionally seeing a fairly serious leak. It doesn't appear to happen consistently (one user has never had one and I can't seem to reproduce it in my test environment), but it does occur regularly in production. I've been using various tools to poke around in a mini-dump (w/ full memory) and I've seen a few potential problem areas, but I can't seem narrow it down any further. Using PerfMon I found that the leak appears to be in private unmanaged memory. When I open the dump in WinDbg, I get this message: This dump file has an exception of interest stored in it ...Show All

• Software Development for Windows Vista ICredentialProvider

  Did anybody make a successful user logon using the new ICredentialProvider interface My credentials are displayed, but I can't make them to logon. And what worse - after 20 or 30 seconds, the winlogon crashes completely with no recovery possible excepting hardware reset. I thought I basically did something wrong and decided to wait for more detailed documentation or some sample code. But MS doesn't seem to put too much effort on improving their SDK documentation and I also found that at least one other programmer has the same problem: http://msdn.microsoft.com/newsgroups/default.aspx query=vista&dg=microsoft.public.platformsdk.security&cat=en-us-msdn-windev-winsdk&lang=en&cr=US&pt=&catli ...Show All

• Visual Studio Team System Cannot pass a GCHandle across AppDomains

  While working on my Automaton framework for build automaton with Team Foundation Server I've come upon this rather cryptic exception.

• .NET Development "Plus equals" pattern in IL gives incorrect results

  When people claim to have found a bug in the CLR, I am normally the first person to tell them to go back and find the bug in their own code, since that is far more likely than the problem being in the CLR itself, given how stable the runtime has been since its release. However, I believe I have isolated a case where the runtime, or something operating at or below the IL level, is behaving incorrectly. (Note: the problem I describe here only occurs in version 1.1 of the CLR; version 2.0 does not appear to be affected) This case evolved from a bug I was having in a VB.NET app, but after disassembling the app and playing with the IL code, I am confident that the problem has something to do with the IL itself. Basically I am performing a "p ...Show All

• Visual C++ Pointer Syntax Question

  Hi folks, I recently migrated from VS 2003 C++ to 2005 C++ and started a new WinForms project to test a few things. Something I noticed right away was that the design environment was declaring pointers to objects with the ^ character, rather than a * - and my usage of * was causing errors. What's going on here I've seen the same thing in the MSDN Documentation for a lot of the .NET sample code, but I'm not sure what ^ means and when I should use it... and what has happened to * -Zero Please see http://msdn2.microsoft.com/en-us/library/yk97tc08(VS.80).aspx ...Show All

• .NET Development Best way to create multiline T-SQL in .NET?

  Hello, What is the best way to create multiline T-SQL commands in .NET besides just concatenating a bunch of strings together Thanks Tom Just to add to Greg's reply, the advantage of a SPROC (Stored Procedure) is not only to save you time from typing out the statement, but is much securer than the existing method you are using as well as being faster since it's already compiled at the SQL end. It's also pretty much better practice overall and advisable to use SPROC's than the standard SQL string commands as you are doing now. ...Show All
