GetSaveFileName

Ok, I dont understand why this doenst work. I have a buffer, szFile which holds the file name. and pass that to my OPENFILENAME struct. The dialog opens when I call GetSaveFileName and shows the desired name, but if i change the name of the file and press save and try to access the lpstrFile after the call to GetSaveFIleName the program causes an error.

Code:

static ::OPENFILENAME ofn;
	static char szFilter[] = "Text Files (*.TXT)\0*.txt\0";

     ofn.lStructSize       = sizeof (OPENFILENAME) ;
     ofn.hwndOwner         = hWnd ;
     ofn.hInstance         = NULL ;
     ofn.lpstrFilter       = szFilter ;
     ofn.lpstrCustomFilter = NULL ;
     ofn.nMaxCustFilter    = 0 ;
     ofn.nFilterIndex      = 0 ;
     ofn.lpstrFile         = NULL ;        
     ofn.nMaxFile          = _MAX_PATH ;
     ofn.lpstrFileTitle    = NULL ;       
     ofn.nMaxFileTitle     = _MAX_FNAME + _MAX_EXT ;
     ofn.lpstrInitialDir   = NULL ;
	 ofn.lpstrTitle        = "Save Output As:" ;
     ofn.Flags             = 0 ;             
     ofn.nFileOffset       = 0 ;
     ofn.nFileExtension    = 0 ;
     ofn.lpstrDefExt       = "txt" ;
     ofn.lCustData         = 0L ;
     ofn.lpfnHook          = NULL ;
     
     char szFile[] = "Output.txt";
     ofn.lpstrFile = szFile;
     ofstream out;
    if(GetSaveFileName(&ofn))
    {    if(strcmp(szFile,ofn.lpstrFile)) // this fails even if i select output.txt as name bc lpstrFile is null now?
           {    out.open(szFile,ios::out);
                 ....
           }
           else   
           {   out.open(ofn.lpstrFile,ios::out); // this causes prog to crash
                .....
            }
       }

Did you try using a message box to debug? Have the text outputted to a message box and see exactly what is in there.

Did that. Its all garbage after the call to GetSaveFileName

Didnt change anything, and no it works all magically by itself.
