• Windows Forms Thread Safe Controls

  I understand that writing to properties of Windows Forms Controls in a multithreaded environment is a dangerous thing.  In order to keep things in order, it is necessary to check the InvokeRequired property and Invoke changes through the thread that created it if it is true. My question is: Is the same true for reading a property   What about for  ...Show All

• Visual Studio 2008 (Pre-release) Need help setting up NavigateUri property of an Hyperlink instance

• Visual Basic Newbi for .NET

  I found that MSV6 (VB and C++) still work well on XPSP2. So I'm not sure in the future since .NET was released since few year ago. What info which I should consider to move from MSV6 to .NET Now, I'm developing on XPSP2 and 2K Server and 2K DC. VB6 is likely to work on Microsoft platforms for a long time.  The issues to consider are: VB6 support has ended VB.NET is a much better language than VB6. It is, however, different enough that I believe it's a tough learning curve initially, and certainly a lot of legacy stuff is supported, but should not be used if you can help it. The wizard to move VB6 apps to ...Show All

• .NET Development com interop and framework 2

  I have an application written in vb.net (Visual studio 2003). From this application a com object is instantiated using myObject = CreateObject("comObject.comClass") If this com object is written in vb.net (Visual Studio 2003) everything is fine.

• Visual Studio Team System Integrating with TFS: Use of ExecuteDefaultAction

  We have an internal tool that we use to keep track of work items and a bunch of other stuff. For a lot of reasons, I would really like to start using TFS for what it can handle. In order to make this feasible, I'm going to need to integrate TFS with our existing tool. I'm starting to get a picture of what I need to implement in order to integrate with TFS, but one aspect is still unclear: Suppose that I have a work item that is linked to an "incident" or a "customer" that exists in our internal tool. I would like to have a mechanism to open the incident or customer through our tool's interface from the work item. Is Ex ...Show All

• Visual Studio Custom help filters option in Beta 2 help?

  In VS.NET 2003 I was able to create my custom filter using Help|Edit Filters and then use that filter in search. I can't for the life of me figure out how to do the same in VS 2005 Pro Beta 2. I've installed VSIP for VS 2005 (aka VS SDK) and would like to search on VSIP only. But there is no search filter available for VSIP and w/o any way to create a filter it searches on the whole help system. That returns hundreds of results and it's close to useless. Does anyone know how to create a custom help filter Thanks. Hi Sergey, Thanks for your post.  In VS2005 we removed the Edit Filters feature because the vast majority of ...Show All
