I'm making a progress window for my Program, that is MDI. The progress window will show progress when a windows service is starting or stopping.

I wanted to make the progress window sort of universal, in which the Master Window owns it, and not the MDIChild Window,

I sort of confused here. I need the HWND from the master window to use in CreateWindowEx, but quite sure how to get it, Because I'm loading the Progress Windows from an MDIChild Window, and my create window fails. Actually I'm modeling the window first to make sure it works and looks right before I fully implement it.

BOOL ProgressBar_Popup::_show_ProgressWindow( HINSTANCE hInstance, HWND cWnd ) 
{

	LPWSTR					windowTitle						= L"Progress";

	// Font Variables
	HDC						hdc;

	// Get the Parent HWND
	gProgressBar_Popup_GAC = cWnd;

	// Get the current HDC
	hdc = GetDC(cWnd);
	hProgressBar_Popup_Instance = hInstance;
	
	LoadString(hProgressBar_Popup_Instance, IDC_PROGRESSBAR_POPUP, sz_ProgressBar_Popup_Class, MAX_LOADSTRING);

	// Create and Register the Popup Window
	_register_ProgressBar_Popup_Class(hInstance);
	hProgressBar_Popup = _create_ProgressBar_Popup(hInstance, windowTitle);
	_progressbar_Popup_Center( gProgressBar_Popup_GAC, hProgressBar_Popup );


	return TRUE;
}

ATOM ProgressBar_Popup::_register_ProgressBar_Popup_Class(HINSTANCE hInstance)
{
    WNDCLASSEX wcex;
	wcex.cbSize        = sizeof(WNDCLASSEX);

    wcex.style         = CS_HREDRAW | CS_VREDRAW;
    wcex.lpfnWndProc   = (WNDPROC) _progressbar_Popup_WndProc;
    wcex.cbClsExtra    = 0;
    wcex.cbWndExtra    = 0;
    wcex.hInstance     = hInstance;
    wcex.hIcon         = LoadIcon(hInstance, MAKEINTRESOURCE(IDI_NASE2012_SUWIZARD));
    wcex.hCursor       = LoadCursor(NULL, IDC_ARROW);
    wcex.hbrBackground = (HBRUSH)GetStockObject( WHITE_BRUSH );
	wcex.lpszMenuName  = NULL; 
    wcex.lpszClassName = sz_ProgressBar_Popup_Class;
    wcex.hIconSm       = LoadIcon(wcex.hInstance, MAKEINTRESOURCE(IDI_SMALL));

	if (!RegisterClassEx(&wcex))
    {
        MessageBox(NULL,
            _T("Call to RegisterClassEx failed!"),
            _T("Win32 Guided Tour"),
            NULL);        
    }

    return RegisterClassEx(&wcex);
}

HWND ProgressBar_Popup::_create_ProgressBar_Popup(HINSTANCE hInstance, LPWSTR windowTitle)
{ 
	HWND hWnd = CreateWindowEx(
		WS_EX_TOPMOST,
        sz_ProgressBar_Popup_Class,         
        windowTitle,
		WS_POPUPWINDOW,    
        10, 10,                 
        200, 200,               
        gProgressBar_Popup_GAC,
		NULL,             
        hInstance,
		NULL
	);	

	if ( !hWnd ) 
	{
		// Create Window has failed
		MessageBox(hWnd,
			L"Progress Bar Popup has failed",
            L"Progress Bar Popup",
			MB_ICONEXCLAMATION | MB_OK);
	}
	else
	{
		ShowWindow(hWnd, SW_SHOW );
		UpdateWindow(hWnd);

	}

	return hWnd;
    
}

Have you considered just showing progress bar in a status bar pane[^]?

I went to lunch and came back, with a new idea, so I deleted the stuff I wrote, and will try to create a some sort of dialog box in the main.cpp.

I have a status bar, but haven't figured out what to put in it, or how to access it.

Why not use the ready made ProgressBar[^] from Microsoft?

I thought it would be a good lesson for to learn how create various windows, and at the time, I was thinking in consumer mode. The progress bar looks very difficult for me now, so I will just create a message or popup window saying that the service is starting or stopping.

Thanks for the suggestion, I'm going to skip ahead to the next task, which is trying to figure out how to delete text I made with drawtext.

I would suggest you look a bit harder. This is quite an easy control to implement and all the hard work of painting the bar is done for you; all you have to do is set the limits and update the amount completed from time to time. I'm sure if you do an article search here on CodeProject you will find some sample code to help you.

Or perhaps I will just trip over it by accident, Just Joking, and I like the motivational push forward you gave me. Actually after a complete day of failure or experimenting, Things are clearer for me now in the c++ windows world.

I went on to the next project, some sort of Label control in c++, and found that I can use CreateWindow to make a Label, Textbox, ComboBox, and a Progress Bar.

So I replaced my Drawtext and created a STATIC in the same place, and I will make a progress bar under it.

Since I painted by background white, I need to figure out how to paint the Label and Progress background white as well.

// Create the Operational Status Text
		txt_Website_Default_Status = CreateWindow(TEXT("STATIC"), TEXT("Press Next to begin the programming"), WS_CHILD | WS_VISIBLE | SS_LEFT,
			winWidth - 300,
			winHeight - 250,
			275, 20, hWebsite_Default, (HMENU)IDC_WEBSITE_DEFAULT_LABEL, GetModuleHandle(NULL), 0
		);
		SendMessage(txt_Website_Default_Status, WM_SETFONT, (WPARAM)hFont_Label, FALSE);
		ShowWindow(txt_Website_Default_Status, SW_SHOW);

I am not certain, but I think you have to use Subclassing[^] in order to do that.

I ended up adding this to the WndProc, Looks like it paints the background on STATIC.

Yesterday was a big day, I learned how to create controls, and handle them during the wizard process, in which the window updates with progress status text and the progress bar.

Today I will try to figure out how to paint the progress bar to the default theme.

case WM_CTLCOLORSTATIC:
            SetBkMode(hdcStatic, TRANSPARENT);
            return (LONG)hbrBackground_White;
            break;
