I want to draw on a control,but the Dialog app will draw it automatic!
-
In a DLG based app,I want to draw something on a CONTROL (static) and there are some another CONTROL on the Dialog. I Get the DC of the Static control and draw something on it,but failed.I see nothing on the static control.So I delete the sentnce
CDialog::OnPaint()And then,all of these control except the staitc can't be seen.(they are not being paint) I want to paint the Static control but hope the other control will draw it themself! How can I do? Thank you for your help! Don't look at me in that way! -

Don't look at me in that way!from the MSDN under GetDlgItem, changed to be a CStatic, assuming you are using the MFC // uses GetDlgItem to return a pointer to a user interface control CStatic* pStatic; pStatic= (CStatic*) GetDlgItem(IDC_STATIC1); pStatic->SetWindowText(_T("Hello world"));

I am working from memory here. In that case the best method, I think, would be to subclass the control. Or you could try get the CDC of the static control, using my #1 method and use this to paint, also add the paint logic into the OnPaint. BUT the control may decide to paint it it's slef therefore overwriting what you have put there! I use this method to place a bitmap into a static control.
