To get this task done, my first instinct was to catch the WM_ERASEBKGND in CMainFrame and do the FillSolidRect there. But I soon realized that approach didn t do anything other than make the frame flicker and show red only when it s being resized, otherwise the gray background was completely intact. Not exactly what I was looking for. Suddenly it became a little mystery. Why doesn t the background of the frame change when I fill it with a color in the frame s WM_ERASEBKGND handler? So I went on a hunt, I went through a lot of the CMDIFrameWnd and CFrameWnd code looking for methods that would draw on the frame, and there was not much there. I finally ended up at CMainFrame::OnCreate method, I set a breakpoint and stepped through the CMDIFrameWnd::OnCreate method. After what seemed to be hours of searching I came across the following code in CMDIFrameWnd::CreateClient:

请根据提示输入参数，运行后会在运行目录生成NTCADList.txt文档；AD值较多时，提示框可能显示不完全，但在文本文档里的数据是完整的。注意：如不输入参数或输入错误参数会导致运行出错！计算参数仅供参考！(According to the prompt input parameters, run the NTCADList.txt file will be generated in the run directory AD value is more, the prompt box may display is not complete, but the data in the text file is complete. Note: if you do not enter a parameter or enter the error parameter, you can run the error! Calculation parameters for reference only!)
