I have a program which could open multiple floated windows. I'd like to hide all of windows of this program.
I create custome function, but I cannot figure out a way to get the floated windows' handlers.

IntPtr[] windowHandles = BFS.Window.GetWindowsByText("*WebStorm*");


foreach(IntPtr theHanlder in windowHandles){
// Hide the window
ShowWindow(theHanlder, ShowWindowEnum.SW_HIDE);

// ***** The main window is hiden, but how can I hide the floated window also? *******

}

The program is WebStorm, a JavaScript IDE. https://www.jetbrains.com/webstorm/

But the BFS.Window.GetChildWindowByClass() does not return any window handler.
Please see my funciton below:

IntPtr[] windowHandles = BFS.Window.GetWindowsByText("*WebStorm*");
IntPtr childWinHandle;




foreach(IntPtr theHanlder in windowHandles){
// *********** not work!!
childWinHandle = BFS.Window.GetChildWindowByClass(theHanlder, "SunAwtFrame");
ShowWindow(childWinHandle, ShowWindowEnum.SW_HIDE);

// This line works, the main windows are hidden.
ShowWindow(theHanlder, ShowWindowEnum.SW_HIDE);



}
