Get Handle of GUICtrlCreateObj()

[tatane 3]

Hi,

I'm trying to get the handle of the control id return by GUICtrlCreateObj.

I know that GUICtrlGetHandle can't retrieve it. Is there another way ?

I have to identify the control object I clicked on to change is size and there is several control object (same type) in my window.

I already am able to get this handle when I click the control, what I need is get the handle as soon as i'm creating the control object.

Thanks.

So if you use something like $idObject = GuiCtrlCreateObj(...) why can't you use $idObject to make your changes?  Or am I missing something.

Because when I click on the control object (let's say a rectangle in my GUI), I don't know what object it is. So I want to compare the handle/control id of this object to the one I created before. The problem is when I create it via GuiCtrlCreateObj(...) , I get an autoit control identifier and no handle to compare.

I should precise that I create more than one gui control object through a loop and the only thing I can keep track is the autoit control identifier.

Can you post your code?

I'm using a dll (vncx.dll) to create COM Object.

The object is hard coded for testing.

The comparison should be placed in the  IVNCViewer_BeforeMouseUp function (where I detect the click and get the handle).
