A wiec mam maly problem z GetSaveFileName dialog pokazuje sie ale przy nacisnieciu OK wyskakuje blad pamieci (pamiec nie moze byc read ... )

char saveFile[300];
OPENFILENAME save;
                        save.hInstance = hInstance;
                        save.Flags = OFN_LONGNAMES|OFN_OVERWRITEPROMPT;
                        save.hwndOwner = hWnd;
                        save.lCustData = NULL;
                        save.lpfnHook = NULL;
                        save.lpstrCustomFilter = NULL;
                        save.lpstrDefExt = "html";
                        save.lpstrFile = "strona.html";
                        save.lpstrFileTitle = saveFile;
                        save.lpstrFilter = NULL;
                        save.lpstrInitialDir = NULL;
                        save.lpstrTitle = "Zapisz jako ...";
                        save.lpTemplateName = NULL;
                        save.lStructSize = sizeof(save);
                        save.nFileExtension = NULL;
                        save.nFileOffset = NULL;
                        save.nFilterIndex = NULL;
                        save.nMaxCustFilter = 60;
                        save.nMaxFile = 300;
                        save.nMaxFileTitle = 300;
                        if((GetSaveFileName(&save))!=0)
                        {
                        //      MessageBox(hWnd,saveFile,"INFO",MB_OK);
                        }

Prosze o pomoc :) ewentualnie jakis maly przykladzik :)

ofn.lStructSize = sizeof (OPENFILENAME) ;
ofn.hwndOwner = hwnd ;
ofn.hInstance = NULL ;
ofn.lpstrFilter = szFilter ;
ofn.lpstrCustomFilter = NULL ;
ofn.nMaxCustFilter = 0 ;
ofn.nFilterIndex = 0 ;
ofn.lpstrFile = "NazwaPliku";
ofn.nMaxFile = MAX_PATH ;
ofn.lpstrFileTitle = NULL ;
ofn.nMaxFileTitle = MAX_PATH ;
ofn.lpstrInitialDir = NULL ;
ofn.lpstrTitle = "jakiś tytuł";
ofn.Flags = OFN_OVERWRITEPROMPT;
ofn.nFileOffset = 0 ;
ofn.nFileExtension = 0 ;
ofn.lpstrDefExt = TEXT ("bmp") ;
ofn.lCustData = 0 ;
ofn.lpfnHook = NULL ;
ofn.lpTemplateName = NULL ;

GetSaveFileName (&ofn);

Tak dziadek Petzold tego używa. Nie sprawdzalem tego twojego, ale to napewno działa.

Działa idealnie THX :)
