API Color Problem

I am making an app using only API(no MFC).Now ,the problem is that i don't know how to change the backcolor of a window or the text in that window.I tried to use the SetBkColor function but don't know how.I don't know how to use the COLORREF structure.
Any help appreciated.

I also code in only API and i would also like to know how to do this.

COLORREF isn't a structure. It's a typedef alias (a type that is created from another standard type, in this case an unsigned long).
So, you pass the values as:

Code:

---

SetBkColor(..., RGB(255,255,255), ...);

---

...using the RGB macro. The values are stored as 0x00BBGGRR internally.

I tried this but it doesn't work:

Code:

---

HWND db=FindWindow(NULL,"bb");
HDC dbdc = GetDC(db);
SetBkColor(dbdc,RGB(255,0,128));

---

WHY??

Okay, I'm not exactly a C++ expert, but:

Code:

---

ATOM MyRegisterClass(HINSTANCE hInstance)
{
        WNDCLASSEX wcex;

        wcex.hbrBackground        = GetSysColorBrush(COLOR_BTNFACE) ;

//Other wcex stuff

---

Works fine.

Also:

Code:

---

                case WM_PAINT:
                        HDC hdc;
                        PAINTSTRUCT ps;
                        RECT rct;
                        HBRUSH hBrush;
                        POINT p;
                       
                        GetWindowRect(hWnd, &rct);

                        p.x = rct.top;
                        p.y = rct.left;
                        ScreenToClient(hWnd, &p);
                        rct.top = p.x;
                        rct.left = p.y;
                       
                        p.x = rct.bottom;
                        p.y = rct.right;
                        ScreenToClient(hWnd, &p);
                        rct.bottom = p.x;
                        rct.right = p.y;

                        hBrush = GetSysColorBrush(COLOR_BTNFACE);
                        hdc = BeginPaint(hWnd, &ps);
                        FillRect(hdc, &rct, hBrush);
                        DeleteObject((HGDIOBJ) hBrush);
                        ReleaseDC(hWnd, hdc);

                        break;

Works I think.

I hope.

Oh, well.

Bye!
