I am using the control in a C++ dialog. How can I add images to the control at design mode?
The control provides an Images panel that holds the icons of the control. The ShowImageList property specifies whether the Images panel is visible or hidden at design mode. In C++, the Images panel is behind the environment window. In order to insert new icons to the control, you need to locate the Images panel by minimizing the top windows. By dragging icon, dll, or exe files to the Images panel, you can insert new icons to the control. After you add icons to Images panel, you have to resize the control and to save the project.
