Hi there. I''m trying to configure my windows application.

Click button->open the new window.
What i have:
i have close enough what i want, but the child window has the same style with main window. Help, please. Here the code:

推荐答案
首先，您必须使用CreateWindow Ex ()函数而不是CreateWindow()创建一个按钮.
第二，您应该在About()中进行相同的代码.祝您好运！
The first, you have to create a button with CreateWindowEx() function, not CreateWindow().
The second, you should make the same code in About(). Good luck!
您正在使用与主窗口相同的样式创建子窗口，因此其外观将相同.您需要使用其他类，并确保其使用WS_CHILD样式创建非主窗口.
You are creating your child window using the same style as your main window so it will look the same. You need to use a different class and make sure it uses the WS_CHILD style to create a non-main window.
我决定使用对话框窗口.我收到了与此有关的确切信息.
I decided to use dialog windows. And i received exactly information about this.
