• Visual C++ Share Projects in one solution

  Dear all, I create two projects, say A and B, in one solution in VC.net 2003. They are basically 2 executable applications, A.exe and B.exe.   In project A, it uses some classes created in project B. I include the header B.h in A.h, and add Additional Include Directories to which B.h resides.   Compile is OK but when linking it looks like the LINKER does not know where to link obj in B project and gives the error messages like this: ATest error LNK2019: unresolved external symbol "public: __thiscall HelloWorld::~HelloWorld(void)" ( 1HelloWorld@@QAE@XZ ) referenced in function _main I do not want to c ...Show All

• Visual Basic Problem with form and the window designer.

  Hi, I have a project who have some forms. The first one is named form1 as usual. But, I do have a problem. In my solution explorer, I don't see the Form1 (Design). I only see it's code, not it's design (in the designer) so I can't modify it's controls. What is weird, when I try to add this form to my existing project, it imports without any error and it compile exactly how it's supposed to be. Here's the structure of my project : Form1.vb (when I click on this, it doesn't start the designer) Form1.designer.vb Form1.resx Form2.vb Form2.designer.vb Form2.resx Can ayone help me asap please Thanks Nuxus ...Show All

• Software Development for Windows Vista EventSinkActivity flow in Sequential Workflow

  Hi ! I am successfully created a sequential workflow with more EventSinkActivities. Let's call them A1, A2, A3. The flow is A1 -> A2 -> A3. I noticed that if I raise the  event for A2 before that for A1 nothing happens. This is OK, but as soon as I raise the event for A1 the earlier call to A2 is executed automaticaly afterwards. This means that some sort of queuing exist. I would really like to throw an Exception if someone tries to invoke an activity that is not the current one, or at least to cancel that call. Is there any chance to do that Many thanks Hi Arjun, thanks for your reply ...Show All

• Visual Studio Team System Proxy Configuration for Dummies

  Hi, my coworker and I just can't get the proxy setup straight. I started a test setup where I have one TFS and one client. The client can connect directly to the TFS without a problem, now I want to do the same, but use a proxy (we will later do this between remote locations with a slow connection). I have some really basic questions and I guess I just did not understand how exaclty the proxy works. a) Where do I have to install the proxy portion (the setup in the proxy folder on the TFS CD) I assume that this goes on the machine that is the client to the actual TFS server. Like this: TFS Server ----WAN connection---- Proxy &Client ...Show All

• Visual C# Questions about Objects in C#

  1. Do we need to pass objects by ref, if we want to have the changes made in a calling function 2. And the same question for the objects passed by Remoting 3. Do we really gain performance in calling Dispose method of DataSet while leaving from a function(the dataset is no longer required) If yes, then what does the Dispose do there Is it freeing the memory occupied by the objects If yes, then basic definition of GC itself gone right. And while the function got executed the DataSet objects declared within the function will also be removed from the reference list. Then is it required to do a Dispose while leaving a function.

• Visual Basic Imports System.Net Intellisense?

  I've been using Visual Studio 2005 Beta 1, and I really like it.  Yesterday I ran into my first problem with it though.  My question is, when you pull up intellisense by hitting ctrl + space, what is now hidden when you view the "all" intellisense tab Here is an example of the problem that I ran into yesterday.  In Visual Studio 2005 I created a new VB Windows Application.  This Windows Application connected to a Web Service as a Web Reference, and now I wanted to pass the Web Service Credentials.  Previously in Visual Studio 2003, I typed in at the top of the page: imports System.Net This would allow ...Show All

• Visual Studio Team System Any idea when MSFWinBuild will become available?

  Hi I have checked both places mentioned, on MSDN and GotDotNet, where I could get MSFWinBuild but neither place seems to have it.  Is there any indication when it will be come available Cheers Brett I've been working for some time now on customisation of the MSF Agile template. Given that there is no immediate sign of MSFWinBuild, I've been trying a workaround by uploading the source version of the template after testing it thoroughly in standalone on my local machine.
