A quick addendum: I was able to get this function to be much shorter
and compact while providing more useful functionality for my program as
follows. I basically took out a bunch of unnecessary stuff (not shown:
the corresponding edits to the header file and the function call in
OnFileOpen() to reduce the number of parameters to what's given here).

BOOL CCoilApp::DoPromptOpenFile(CString& fileName, DWORD lFlags, BOOL
bOpenFileDialog)
{
    CFileDialog dlgFile(bOpenFileDialog, NULL, NULL, OFN_HIDEREADONLY |
OFN_OVERWRITEPROMPT, NULL, NULL, 0);

    dlgFile.m_ofn.Flags |= lFlags;

    TCHAR file[_MAX_PATH];
    GetModuleFileName( NULL, file, _MAX_PATH );
    CString mod_dir = file;
    mod_dir = mod_dir.Mid( 0, mod_dir.ReverseFind( '\\' ) );
#if _DEBUG
        mod_dir = mod_dir.Mid( 0, mod_dir.ReverseFind( '\\' ) );
#endif
    mod_dir += "\\HX";

    dlgFile.m_ofn.lpstrFilter = "Coil files (*.dat)\0*.dat\0All files
(*.*)\0*.*\0";
    dlgFile.m_ofn.lpstrTitle = "Open coil file";
    dlgFile.m_ofn.lpstrFile = fileName.GetBuffer(_MAX_PATH);
    dlgFile.m_ofn.lpstrInitialDir = mod_dir;

    INT_PTR nResult = dlgFile.DoModal();
    fileName.ReleaseBuffer();
    return nResult == IDOK;
