Had the same problem and found the solution in one of Microsoft's articles. At the beginning of the.cpp file, after the includes, I put the following: #ifdef MessageBox #undef MessageBox #endif The problem seems to be caused by a confliction in MessageBox declarations between the .Net declaration and the one in the windows.h file. Cheers

Nick's advice is what I would give you, too. But I wanted to throw in some things here: You'll also want to read articles on sites like this one and C-Sharp-Corner[^]. tom76 wrote: in C++ I'd use iostream.h for i/o operations, but in C# I do not know what I would use System.IO has many helpful classes for this - File and FileInfo for working with files, Directory for working with directories, Path for working with paths, and FileStream, TextWriter, TextReader, StreamReader, StreamWriter, etc for reading and writing to files. **"It is impossible to rightly govern the world without God and the Bible." -- George Washington FLUID UI Toolkit | FloodFill in C# & GDI+**

See how good CP is? :) Almost so good, it can help yourself :) leppie::AllocCPArticle("Zee blog"); Seen on my Campus BBS: Linux is free...coz no-one wants to pay for it.

Thanks Obseve everything, remember more...

In VC++, just add version info to your resources. things could always be worse...

It loads a bitmap from a resource. If you look at the MFC source code, you'll find that the one that takes a UINT actually calls the one that takes a LPCTSTR to do the work. All resources are loaded via strings. The UINTs have to be coerced into looking like strings so that Windows can load them.

From the File menu, select Open Workspace. Look for files of type *.mak.

Sorted it - user error I think. I put a watch on m_hWnd and after calling the function it said the expression could not be evaluated. I had allocated the buffer too small so it seems the buffer was overwritten, and the variable m_hWnd was overwritten! Obseve everything, remember more...

I'll try it, thanks. Obseve everything, remember more...

Check this, BOOL bFlag = AllocConsole(); HANDLE hnd =GetStdHandle(STD_OUTPUT_HANDLE); DWORD dw = GetLastError(); unsigned long i; WriteConsole(hnd,"test", 4,&i , NULL);

Oh, I thought you were trying to do a swap. This is an add, and I'm not sure it has any value over simply adding without the function call. It will not compile if the type in question does not have an operator +. Because your return type is 'int' it also will not compile unless the template argument is a number, and it will give warnings because it will strip floating point numbers down to an int. Swap would look like this ( except you'd add the template arguments being stripped by the site because neither of us checked 'show message as-is' ) template void Temp1(X &A, X &B) { X Var; Var = A; B = A; A = Var; } Christian No offense, but I don't really want to encourage the creation of another VB developer. - Larry Antram 22 Oct 2002 C# will attract all comers, where VB is for IT Journalists and managers - Michael P Butler 05-12-2002 Again, you can screw up a C/C++ program just as easily as a VB program.

That's very handy, thank you. I'm going to play with one of the examples to see how I go. Annoyingly the bits I need are not written in, it's just //... Grrr! Daniel:confused: Obseve everything, remember more...
