如何在单击我自己创建的窗口上的菜单时在我的窗口上显示内容

Hello Coders，

我在Win32 API的代码块中用c ++编写程序。我创建了一个名为New的菜单窗口，其中有一个选项Display（即New-> Display）。



我希望它点击显示一些数据应该在同一个窗口显示（&不要画画）（不是像Messagbox那样在另一个窗口中）。



请你告诉我我怎么能这样做，如果你有任何关于你管视频的链接对我有帮助。



谢谢预期



我尝试过：



我尝试过IDM，但代码块不支持。

Hello Coders,
I am writing a program in c++ in code blocks on "Win32 API". I have created a window with menu named "New" and there is a option in it "Display"(i.e. New->Display).

I want that on clicking the "Display" some data should be displayed( & not paint) on the same window(not in another window like messagbox).

Please Can u tell me how can I do this and if u have any link to video on you tube helpful for me.

Thank you Anticipation

I have tried IDM but it was not supported in code blocks.
