Displaying painted areas on Property Sheet

[koumodaki]

I have a property page with a static control area defined as CONTROL "",IDC_TEMP_GRPH,"Static",SS_GRAYFRAME,154,44,135,129 I am handling WM_PAINT message and the following piece of code gets executed: CDC* pDC = new CDC(GetDC(this->m_hWnd)); HWND hStatic = GetDlgItem(m_hWnd,IDC_TEMP_GRPH); RECT pirect; GetClientRect(hStatic,&pirect); COLORREF bkColor; bkColor = RGB(225,0,0); HBRUSH hBrush = ::CreateSolidBrush(bkColor); ::FillRect(GetDC(hStatic),&pirect,hBrush); The problem is I am not able to see this solid color block. It appears blinking while I drag the Property Sheet but disappears when I switch to next page and switch back to that page. Can anyone please tell me what is missing here?

Rather than painting from your dialog, try over-riding the static control. Have a look at this article: http://www.codeproject.com/KB/miscctrl/generic_picker.aspx[^] It's not talked about in the article itself, but it uses an owner draw static control to do the pretty picture bit. Feel free to stealreuse it from me. Iain.

First, use CPaintDC in the WM_PAINT message handler, not GetDC, and second, when you do this:

GetClientRect(hStatic,&pirect);

You get the client area of the static, not its position in the client area of its parent. If you want to know where the static lies inside of its parent use some coord mapping functions or simply this:

RECT pirect;
GetWindowRect(hStatic,&pirect);
ScreenToClient(&pirect);

Thanks. But I foound out what was missing from my code. I had to add PAINTSTRUCT ps; HDC hdc = ::BeginPaint(m_hWnd, &ps); at the start and ::EndPaint(m_hWnd, &ps); at end of my code snippet and it works. :)

I am using SDK so CPaintDC is ruled out. So I have to add BeginPaint() and EndPaint() instead fro it to work.

Thanks. I've got so much useful code from CP, I like to give back when I can. I hope you've added yourself to pointy haired thread hijackers list... Iain.

Well, since I'm (together with Rajesh) the proud founder of the Brigade, my name is necessarily there. :)
