c++ - Call to GetOpenFileNameA causes common dialog error 2 -


i'm trying open dialog box using getopenfilenamea. however, dialog not open. instead, nice commdlgerror 2. searching google , stackoverflow error did not produce helpful results.

confusingly, code works on school computer uses visual studio, albeit different version.

note: variables not declared in block of code "global" variables accessible within main code module.

void getinputfile() {     char szfilenamein[max_path];     char szfilenameout[max_path];      // input file name     openfilename ofn;     zeromemory(&finputpath, sizeof(finputpath));     zeromemory(&ofn, sizeof(ofn));     ofn.lstructsize = sizeof(ofn);     ofn.hwndowner = null;     ofn.lpstrfilter = lpwstr("any file\0*.*\0");     ofn.lpstrfile = lpwstr(finputpath);     ofn.nmaxfile = max_path;     ofn.lpstrfiletitle = lpwstr(szfilenamein);     ofn.nmaxfiletitle = max_path;     ofn.lpstrtitle = lpwstr("select input file");     ofn.flags = ofn_dontaddtorecent | ofn_filemustexist;     if (getopenfilenamea(lpopenfilenamea(&ofn))) // user selected input file     {     }     else {         // error         tchar error[max_loadstring];         wsprintf(error,text("%i"),commdlgextendederror());         messagebox(null,error,text("error"),mb_ok);     }  }

those awful (lpwstr) casts tell me compiling unicode defined, openfilename struct using openfilenamew; given using getopenfilenamea, have use openfilenamea (or use straight getopenfilename wide strings).

(and remember that, rule of thumb, if have cast pointers to/from different void * , similar, doing wrong; adding pointer casts silence compiler, not make error go away)
