How to change background color of dialog box..

[Shah Satish]

Hi !!! I have created one dialog box ( picture control).I want to change background color of my dialog box. I did some steps but there is no change..I dont know may be some where i did mistake.. My steps are :- In the Header file of my Dialog(ga_dwgpv.h),added a CBrush variable ( member variable ). Assuming that i have declared it as such.

CBrush m_brush;

In the OnInitDialog function of my dialog, added this code to create the brush.

m_brush.CreateSolidBrush(RGB(150,50,100));

Handle the WM_CTLCOLOR message in my dialog box and in the OnCtlColor function, added this code.

m_brush.CreateSolidBrush(RGB(150,50,100));

Is this correct ?? There is no error in programme. Any other method to change backgroung color ?? Thanking you Shah

show the whole function. i suspect you to call the base class' function, or not to return the context

You seem to almost have it. just return m_brush from the function. Maybe this[^] can help you?

So, you want to have a picture-control on the dialog, which displays the background color of the dialog? The same color the dialog is alredy showing? Odd! :~ What is the picture control to begin with? A CBitmapButton? Well your PictureControl probably wants a bitmap, wo create one with the background color brush and set it as bitmap in the control.

Who, I mean what code, is rendering the dwg-file? Most probably this code has a setting to set the background-color of its rendering? You can also subclass the control and in the derived class handle WM_ERASEBKGND. There you use the background-colored brush to erase the background.

You can use of

pDC->SetTextColor( m_clrText ); //set color of text
pDC->SetBkColor( m_clrBkgnd ); // set color text background
return m_brBackground; // set background

On the WM_CTLCOLOR
