I can not find the invisible figure when I used the ::FindWindow function in My Windows application

Hello:

Hi,

an invisble MATLAB figure does not get a Window Handle, so thats why you cannot find it.

You can obtain that by testing with a visible figure where it works, then you make that figure invisible and visible again and you will obtain that the Window Handle changed.

I haven't tested if that is a general JVM behavior of invisble windows or MATLAB specific.

In the case you try it out, let me know ;)

My friend! but,I do not want the figure show up when i have not moved it. this is my job: 1、find the invisible figure's Handle in my VC program 2、move it 3、show the figure but,I failed.

Friedrich's point is that there is no handle for the invisible figure. The window is getting destroyed at the Windows level (or something similar) when it is made invisible.

Overall: Why not moving the figure from the MATLAB side with MATLAB Code? Why that compilcated way using C/C++ Windows API functions.
