How to stop the child windows child window to be disappeard?

Question

Hii Members,

 

I am learning C# (2008) with Windows Application and I came to know about a difficulty during my experiments.

 

There is a parent window (MDI) and that contains many child windows. In a child window, there is a command button that opens a new form when clicked. The problem started when I use Alt+Tab to check something else...

 

Please see the screen shots... I have described in detail in the screenshots.

 

Dear Members, Please note that there is no error or bug in the form, they are working fine but, kindly try to understand my concern and give me solution of the same, if possible or, if there is a solution. Once again, I am using C# with MS VS 2008.

 

Thank You

Mayank Jani
