Looking for something like this?
char passph[128];
BOOL CALLBACK
pass_proc (HWND hwnd, UINT uMsg, WPARAM wParam, LPARAM lParam)
{
switch (uMsg) {
case WM_INITDIALOG:
SetForegroundWindow (hwnd);
return TRUE;
case WM_COMMAND:
switch (LOWORD (wParam)) {
case IDOK:
GetDlgItemText (hwnd, IDC_PASSPH, passph, sizeof (passph));
case IDCANCEL:
EndDialog (hwnd, LOWORD (wParam));
break;
default:
break;
}
break;
default:
break;
}
return FALSE;
}
int
get_passph (char *buf, int buf_len, int unused)
{
if (DialogBox (myInst, MAKEINTRESOURCE (IDD_PASSPH),
hwndMain, pass_proc) == IDOK) {
strncpy (buf, passph, buf_len);
return strlen (passph);
}
return 0;
}
