//
//  Function:   OleUIPromptUserA
//
//  Synopsis:   converts call to ANSI version into call to Unicode version
//
//  Arguments:  [nTemplate]  - template ID
//              [hwndParent] - parent's HWND
//              [lpszTitle]  - title of the window

//              forwarding the call.  The other parameters do not need to
//              be converted because the template ID will indicate the dialog
//              that contains the correct wsprintf formatting string for
//              converting the other ANSI parameters to Unicode when the
//              function calls wsprintf to build it's text.
