I want to use the GetOpenFileName function in D (with DFL btw), the problem is, the linker doesn't find it cause it searches for _GetOpenFileName
but comdlg32.dll seems to export it as GetOpenFileName.

pragma(lib,"comdlg32.lib");
export extern(C) BOOL GetOpenFileName(OPENFILENAME* lpofn);

Never mind, was a really dumb mistake, I forgot that I have to use GetOpenFileNameA resp. GetOpenFileNameW.

Got another problem now. GetOpenFileName fails with error code 2 (Initialization error) Can't figure out why it fails:

		string filter="DK2 string files(*.str)\0*.str\0\0";
		string filename;
		filename.length=400;
		OPENFILENAME ofn;
		memset(&ofn,0,ofn.sizeof);
		ofn.lStructSize=OPENFILENAME.sizeof;
		ofn.hwndOwner=null;
		ofn.lpstrFilter=filter.ptr;
		ofn.lpstrCustomFilter=null;
		ofn.lpstrFile=filename.ptr;
		ofn.nMaxFile=filename.length;

		if (!GetOpenFileNameA(&ofn))
		{
			debug msgBox("CommDlgError: "~std.string.toString(CommDlgExtendedError()));
			return;
		}

Maybe because of hwndOwner? But I don't know how to get the hwnd in DFL.

Controls and Forms have a handle property to get the HWND, but why not just use DFL's OpenFileDialog: http://wiki.dprogramming.com/DflDoc/Filedialog - it wraps all this messy winapi into a nice class.
