Usage:
NSTS::CProgressBar g_pb;
NSTS::CProgressBar g_pb2;
WM_INITDIALOG:
RECT rcpb = { 0, 0, 100, 20 };
assert (g_pb.Init (hInst, hwndDlg, &rcpb));
assert (g_pb2.Attach (GetDlgItem (hwndDlg, IDC_PROGRESS1)));
assert (g_pb2.SetStep (5));
// 背景颜色
assert (g_pb2.SetBkColor (RGB (128, 128, 255)));
// 进度条颜色
assert (g_pb2.SetIndicatorColor (RGB (255, 0, 0)));
---
assert (g_pb.StepIt ());
assert (g_pb2.StepIt ());
PS:
这只是封装微软的进度条，当然自己实现比较好，可以做美化，以及实现百分比显示。
