Static Control

[Gil Fisher]

There is plenty of information on placing and using controls on dialog boxes. I need to use them on the documnet. I have placed two scroll bars, a button and a static controls on the documnet window. My problem is this: When I try to color the text in the static control by overiding the WM_CTLCOLOR message it does not work. The code is as follows:
HBRUSH MCtrl_DSCUStatic::CtlColor(CDC* pDC, UINT nCtlColor)
{
// TODO: Change any attributes of the DC here
// THis is the reflected one
CBrush hbr;

hbr.CreateSolidBrush( RGB(100,100,100));

pDC->SetTextColor(RGB(255,0,0));

pDC->SetBkColor(RGB(255,0,0));
pDC->MoveTo(0,0);
pDC->LineTo(200,200);

// TODO: Return a non-NULL brush if the parent's handler should not be called
// return NULL;
return hbr;
}

This function does get called and the line gets drawn then the text prints over the line but the color is still black. So far the only soultion I have is to overide the onpaint function. This basically defeats the purpose of using a static control. Any suggestions? I would also like any information on using controls on a doc window. There is absolutly no info on this! Thanks!

The problem is that your brush is destroyed when you exit the method (local variable). Use a member variable instead.

Your HBRUSH is a local variable, so it gets destroyed once your code jumps out of the function.
Use a member variable say HBRUSH m_MyBrush;
Create a brush whenever neccessary by calling CreateSolidBrush, and if you are creating a new brush THEN PLEASE MAKE SURE THAT YOU DESTROY THE OLD BRUSH by calling DeleteObject.

If your color requirements are not changing then you may create a brush once only(in the very beginning ) and use it repeatedly, provided you have not done a DeleteObject on the brush anywhere.

I was able to change the text color of the CStatic controls on my view by overriding OnCtlColor() function, in which I call pDC->SetTextColor() when it's the right control. My problem is I was not able to use the same technique to change the text color of my CButtons controls ...
