Remove Child Window from Parent using WIN API

Solved!
Go to solution

Hello all,

I am using User32.dll to make a parent-child relationship between two VIs. I use SetParent function, and pass the handle of parent VI and child VI to this function. Now, after this relationship has been established, I want to remove the child window from the parent and use it as a independent VI using WIN API. Can anyone help me on this?

 

Thanks in advance!

Hi Fragger Fox,

i think it should be possible if you assign a new parent to the child. Maybe it works if you assign the desktop as new parent.

 

Hope it helps.

I am thinking if that would really work. Since the child already has a parent, just giving it a handle of other parent would make it a child of other parent, in this case, the desktop? Would it automatically remove itself from its parent?

Also, how can we get the desktop handle?

Hi Fragger Fox,

from the description of the "SetParent" function, i think it will change the parent. You can get the desktop handle with the "GetDesktopWindow" function.

You should be able to set a NULL handle to undo the parent-child relationship and make the child window again a normal top level window. Setting the desktop as parent is probably not the same as being a top level window.
