ShellExecute problem

[Clay L]

In the following code the first ShellExecute statement does not work even though even though strAppDirectory contains the same path as the next ShellExecute statement that does work.

Do I have a dumb mistake that I am missing?


void CDBcalcDlg::OnHelp()
{
char szAppPath[MAX_PATH] = "";
CString strAppDirectory;

::GetModuleFileName(0, szAppPath, sizeof(szAppPath) - 1);

// Extract directory
strAppDirectory = szAppPath;
strAppDirectory = strAppDirectory.Left(strAppDirectory.ReverseFind('\\'));

ShellExecute(hWnd, _T("open"), _T("C:\\strAppDirectory\\dBcalc.chm"),NULL, NULL, SW_SHOWNORMAL);

ShellExecute(hWnd, _T("open"), _T("C:\\Users\\Clay\\Documents\\Visual Studio 2005\\Projects\\Chm_dBcalc\\dBcalc\\Debug\\dBcalc.chm"),NULL, NULL, SW_SHOWNORMAL);
