PocketMatrix

You can use the standard Win32 API for that... that'll make it work well and be portable.

I've tried this and it works fine on my PC. Unfortunately, it refuses to compile for my Pocket PC.
Could somebody help me? I think I use a part of the Win32 API that is not supported under WinCE...
Thanks

OPENFILENAME ofn;
char szFileName[MAXPATH] = "";

ZeroMemory(&ofn, sizeof(ofn));

ofn.lStructSize = sizeof(ofn);
//ofn.hwndOwner = hwnd;
ofn.lpstrFilter = "Text Files (*.txt)\0*.txt\0All Files (*.*)\0*.*\0";
ofn.lpstrFile = szFileName;
ofn.nMaxFile = MAXPATH;
ofn.Flags = OFN_EXPLORER | OFN_FILEMUSTEXIST | OFN_HIDEREADONLY;
ofn.lpstrDefExt = "txt";

if(GetOpenFileName(&ofn))
{
//..
}

Another problem is that you need to have your strings in unicode for WinCE.

By portability, I meant that it works both in WinCE and normal Windows.

In case you're still having problems, check this page out:
)again, remember you'll need to modify everything there for unicode)

Thank you Damian, Sm!rk, ppcStudios and warmi !! It works !! Here is the code I used :

OPENFILENAME ofn;
TCHAR szFileName[MAXPATH] = TEXT("");

ZeroMemory(&ofn, sizeof(ofn));

ofn.lStructSize = sizeof(ofn);
//ofn.hwndOwner = hwnd;
ofn.lpstrFilter = TEXT("Executable Files (*.exe)\0*.exe\0All Files (*.*)\0*.*\0\0");
ofn.lpstrFile = szFileName;
ofn.nMaxFile = MAXPATH;
ofn.Flags = OFN_EXPLORER | OFN_FILEMUSTEXIST | OFN_HIDEREADONLY;
ofn.lpstrDefExt = TEXT("exe");
if(GetOpenFileName(&ofn))
{
}

And using tGetFile from Tillanosoft make it even better !! (just replace GetOpenFileName by tGetOpenFileName)
Thanks again for solving my problem so quickly.
