[GD-Windows] Mind numbing GetOpenFileName Problem

[Paul C. <pa...@pa...>]

All I want is an open file dialog box, but no, windows has to cause me
problems.  Ok, its probably a silly mistake but here goes.
I'm compiling with both these flags set:
#define _WIN32_WINNT 0x500
#define WINVER 0x500

to try and get various things (mousewheel, ...) to co-operate.  The problem
comes when I try and open a file dialog.  The code is below.  The

sticking point appears to be the ofn.lStructSize line.  When set using the
VERSION_400 flag is fails gracefully with CDERR_STRUCTSIZE.  If I use

sizeof( OPENFILENAME ) it just crashes in the kernel on GetOpenFileName.
This should be really simple to get up and running, but I don't know how

get out of this hole I seem to have dug.  With no error message, useful or
otherwise, I'm a bit stuck.

(I apologise for the crap formatting but outlook express has decided to put
double carriage returns everywhere - go figure).

cheers

Paul

Why are you defining the Windows version? Just miss these out and use
sizeof(OPENFILENAME). This is from one of my tools;

char szFileName[256] = {0};        // make sure this is null terminated or
windows barfs
	char szInitialDir[256];

 // Display the OpenFileName dialog. Then, try to load the specified file
    OPENFILENAME ofn = { sizeof(OPENFILENAME), NULL, NULL,
                        _T(".IMF Files (.x)\0*.imf\0\0"),
                        NULL, 0, 1, szFileName, 256, NULL, 0,
                        szInitialDir, _T("Open Mesh File"),
                        OFN_FILEMUSTEXIST, 0, 1, NULL, 0, NULL, NULL };

   if( TRUE == GetOpenFileName( &ofn ) )
    {
