• Windows Forms designer can't load form. Where is 'more information'?

  after going from beta2 to rc1, the designer all of a sudden cannot load my forms anymore. instead, i get the infamous window with the red top that says some errors may go away building the project, while other need code changes. needles to say: the file compiles fine, the form could be opened with the beta2 and vs2003 designers and obviously doing a rebuild doesn't help at all. now what the additional error message says; Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information. ok - great. now how do i retrieve the loader exception property. how can i fix this where can i find more info about whats going on   WM_THXADVANCE thomas woelfer http://www.die.de/blog ...Show All

• Visual C++ This code snippet makes no sense...

  I've come across some code syntax I've never seen. It compiled, but I don't know how, or what it even does! I've been reading a book about DirectX, and in one of the examples, this little piece of code was present: D3DXMATRIX *D3DXMatrixIdentity(D3DXMATRIX *pout); "D3DXMATRIX" is a type, of course. And "D3DXMatrixIdentity" is a function, of course. Now I don't see how this works. Okay, to break it down, first we have a type, which is D3DXMATRIX, then we have the indirection-operator (which I assume is a pointer), and then we have a function (perhaps a call) with a new D3DXMATRIX (pointer) as it's only parameter. How the heck does this work It isn't just a regular function-call. It isn't a function-call that' ...Show All

• Visual Studio Express Editions Problem Adding DLL to C# Project

  Hi, I wrote a simple dll in C++. I am trying to add it to a new C# project but I get this: "A reference to... could no be added. This is a not valid assembly or COM component. Only assemblies with extension 'dll' and COM components can be referenced. Please make sure that the file is accessible , and that it is a valid assembly or COM component" The file I'm trying to add called: Worker_Class.dll Please help, what could be the problem Iram Ah sure, that's just IntelliSense. The brackets [] tell the compiler to look for DllImportAttribute instead of DllImport. So just paste the code like I posted it, and see if it works (after changing the DLL and method name to yours). ...Show All

• Visual Studio 'Build failed' - Approaching deadline, please help!

  for some reason i can no longer build setup projects within visual studio 2005. all the other project types (VSTO, WinForm, class libraries) build just fine. i have narrowed this problem down to the bare bones by creating a new solution consisting of only a new blank setup project. I then tried to build this, but again without success. All I get is a message down in the bottom left hand corner saying "Build failed". I am loathe to reinstall visual studio as this means i will also have to reinstall VSTO, the outlook 2007 template, the web project templates, etc, so this is going to take me all day. Please can anyone offer a solution as im stuck and up against a deadline. As ind ...Show All

• Windows Forms MDI - First Child delay

  I have an application that consists of a prent MDI form. There is a menu tree in which each item equates to a seperate child form. The child forms are seperate assemblies. The problem I am having is that after loading the parent application (warm/cold) the first child form takes alot longer to load than the subsiquent ones. It does not matter which child form is opened first. I am not so much concerned with the start time of the entire application, but the load time of the first child form that is loaded. Any tips would be greatly appreciated. Thanks, Brad Sounds like you're seeing the JIT compiler taking time to compile the assembly. Try using Ngen.exe ... ...Show All

• Visual Studio Team System Confused about install requirements.

  Hi, I have been reading the posts w.r.t install requirements for VSTE DBPro RTM. I have a MSDN Universal subscription and hence have VSTE SP1 installed. That is what came in my MSDN subscription. My understanding is that I can't install VSTE DBPro RTM. Is this right I suppose my first thought is how can this be Then my second thought is how can I get VSTE DBPro RTM installed without changing my install of VSTE (because I need it work, i.e. no trial jazz).
