Using ShellExecute

[ShamusVW]

I am trying to use ShellExecute in my program to open up various files, using the default program depending on the file extension. After reading various posts, I have the following...

#include "qt_windows.h"
#include "qwindowdefs_win.h"
#include <shellapi.h>
...
long result = (long)ShellExecute(0, 0, reinterpret_cast<const WCHAR*>("test.csv"), 0, 0, SW_NORMAL);
QMessageBox::critical(this, "Error", QString::number( result, 'f', 0 ) );

#include "qt_windows.h"
#include "qwindowdefs_win.h"
#include <shellapi.h>
...
long result = (long)ShellExecute(0, 0, reinterpret_cast<const WCHAR*>("test.csv"), 0, 0, SW_NORMAL);
QMessageBox::critical(this, "Error", QString::number( result, 'f', 0 ) );

To copy to clipboard, switch view to plain text mode 

Now the error I get is always "2", which if I'm correct, is "file not found", possibly "path no found". I have made sure that the file is in the same directory as my executable. I have even tried "c:\test.csv", as well as "c:/test.csv", making sure the file is in the root directory.

In another post I read that I need to use "( TCHAR * ) qt_winTchar" since it is expecting a wide character string. But that is apparently old, and I should use ucs2, but I only have fromUcs4(). I really am confused.
