• Visual C++ Problem with VC++ 2003.Net Inheritance and destructors

  I have come upon a weird but probably very simple problem. In Visual Studio.net 2003 I try inheriting a public managed class into a public managed class both of which were created by using the class wizard. If I comment out the destructors the library compiles properly. But if I leave in the destructors or any one of them the inheritance gives a compiler error. Would someone be kind enough to tell me what silly mistake I am making Error Message is fatal error LNK1120: 1 unresolved externals #pragma once using namespace System; namespace StationObjects { public __gc class StationObj { public:    StatioObj(void){}    ...Show All

• Visual Studio Team System SQL Server 2005 April CTP - Invalid SSPI Packet Size

  When I bring up SQL Server Management Studio and attempt to connect to the default database using windows authentication, I get a cannot connect error because of Invalid SSPI Packet Size.  If I try again it works.  This is causing me problems installing the application tier.  Does anyone have a clue what I can do to fix this I'm seeing the SSPI packet size error in the June CTP as well.  I've observed it on two different domains.  I opened a bug in the "MSDN Product Feedback Center" (aka Ladybug) with bugid FDBK30644 to reflect that the June CTP did not fix this.

• Visual Studio Team System How to publish test result to TFS by programming

  I know how to publish a test result to TFS by myself in VS now. What I wanna know is if there is a way to publish the result by some programming approach It seems I can use the PublishTestResultsBuildService.asmx in TFS, I tried but failed, can any one give me an example for that. Thanks I don't think there is an API that you can call to publish the results file to TFS. If you are looking to publish results file outside of VS IDE window then there is mstest.exe command line tool you can use to publish the results. See the help for mstest.exe (mstest.exe / ). Section of mstest.exe / for publishing: The following options are also a ...Show All

• Windows Forms Validation issues (save and new items)

  I implemented validation on my form overriding the OnColumnChanging of the underlying datatable. While this worked ok whenever I step on the control (let's say textbox), put an invalid value, and  leave the control, it  didn't worked in another scenarios: * I want the validation occurs hen I press the Save button * When I do an AddNew on the BindingSource, ColumnChanging event is never fired, so validation does not occur How can I solve these issues Thanks, Matias Any word about this I've just did a proof of concept with the Customers Northwind table.
