Issue with SetBitmap

[CoffeeAddict19]

I'm trying to change the face of a button to a solid color bitmap, but for some reason it's just displaying the button without the bitmap on the front. Here is the code:

CGameOptionsDialog::CGameOptionsDialog(char* lpszName) : CDialog(lpszName)
{
	//initialize graphics
	Problem = mem_DC.CreateCompatibleDC(NULL);
	CBitSolidBkButton.CreateBitmap(20, 20, mem_DC.GetDeviceCaps(PLANES), mem_DC.GetDeviceCaps(BITSPIXEL), NULL);
	mem_DC.SelectObject(CBitSolidBkButton);
	NewSolidBkColor = RGB(220, 20, 60); //default
	NewSolidBkBrush.CreateSolidBrush(NewSolidBkColor);
	mem_DC.SelectObject(NewSolidBkBrush);
	mem_DC.FloodFill(0, 0, NewSolidBkColor);
}

and where SetBitmap is called...

BOOL CGameOptionsDialog::OnInitDialog()
{
	CDialog::OnInitDialog();

...

//initialize controls
	SolidColorSelectButton.Create(" ", WS_CHILD|WS_VISIBLE|BS_BITMAP, CRect(145, 55, 165, 75), this, ID_CHANGE_BK_COLOR);
	Gradient1ColorSelectButton.Create(" ", WS_CHILD|WS_VISIBLE|BS_BITMAP, CRect(145, 85, 165, 105), this, ID_CHANGE_GRADIENT1_COLOR);
	Gradient2ColorSelectButton.Create(" ", WS_CHILD|WS_VISIBLE|BS_BITMAP, CRect(175, 85, 195, 105), this, ID_CHANGE_GRADIENT2_COLOR);
	SolidColorSelectButton.SetBitmap((HBITMAP)CBitSolidBkButton);

if(Problem == FALSE)
        MessageBox("Problem", "MSG", MB_OK);

        return TRUE;
}

The "Problem" message box isn't popping up, so I'm pretty shure that the device context got initialized right (it's a class member, so scope isn't an issue). Any ideas on what is wrong? Thanks.

1. try adding a bitmap resource, and then using that in your line: SolidColorSelectButton.SetBitmap((HBITMAP)CBitSolidBkButton); that way you can tell whether it's a bitmap-creation issue OR a button creation issue. 2) You have the line: mem_DC.SelectObject(CBitSolidBkButton); Did you select the bitmap back OUT of the device context later on???
