trSpeed.SetInitials(10, 10, 250, 25);
trSpeed.hInstance = hInstance;
trSpeed.hWndParent = hWnd;
trSpeed.Create();
trSpeed.SetRange(0, 19);
trSpeed.SetTickFrequency(1);
trSpeed.SetPosition(5);
int a = (int) trSpeed.GetTickPosition();
char b[32];
_itoa(a, b, 10);
MessageBox(NULL, SetText(b), "Title", NULL);
I want to get tick position of a trackbar represented by
trSpeed class, but the code above ALWAYS returns 25.
Am I doing something wrong?
