Recommended Posts

Hi I have a odd problem with WM_NCHITTEST

I have this code witch I wrote ages ago, but short time ago I updated it with a top bar that i could use to d'n'd to :

#include <ButtonConstants.au3>
#include <EditConstants.au3>

And it works on  my laptop, and several other pc's - but in a fresh install at my workpc the minimize and close button at the titlebar don't work?

And whats more odd is that at the same pc in an old install off windows 7, it works as it should.

So at the same pc, with win7 it works and it doesn't - do I miss some extra in my fresh win7 install that i have in the old one?

I don't know what to say, except im on W10 64 and it works. What is the error?

EDIT: in fact, i would add this to it:

GUISetOnEvent($GUI_EVENT_MINIMIZE, "_Minimize")

The script above worked on my Win 10 x64 computer as well, no problems found with it.

If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

Yeah on my win10 it also works, but in some win 7 it don't - and that's whats odd

It don't give any errors, the prog works except for the minimize and close button :/



Okay, I haven't tried to edit the code yet - course I was hoping that some on could give me an reason for why it did work on some windows but not on others. - But yes with your updated code IT works :) thx



Yeas again it also worked on my win 10, and my old win 7 installation - also on my laptop with win 7, but at my fresh installed win 7, it didn't :(

And that's why I was thinking that I might miss some required files in the installation for the code to work properly.


I also just tested it on a VP with a ½ updated win7 installation, and there it didn't work either.
So I guess that for the above code to work, I need to install something else, but what??
