I re-read the manual, and don't see this explained. So I post it as a bug, since it is an unpleasant and unexpected side effect, even if the workaround is simple.

The problem is that when I use GuiControlGet Pos after a Gui Submit (for example), the content of the variable of the control is overwritten with an empty string.
Code:
Gui Add, Edit, ve, Sample Text
Gui Add, Button, gL1, Test 1
Gui Add, Button, gL2, Test 2
GuiControl Focus, Button1
Gui Show, w300, GuiControlGet Bug
Return

L1:
   Gui Submit, NoHide
   MsgBox %e%
   GuiControlGet e, Pos
   MsgBox %e%`n%eX% %eY% %eW% %eH%
Return

L2:
   GuiControlGet e, Pos
   Gui Submit, NoHide
   MsgBox %e%`n%eX% %eY% %eW% %eH%
Return
If this is hard to correct in code (usage in functions?), I would be happy with a simple warning in the manual. The fact that we cannot specify a specific variable name for this operation (I expected the syntax to be GuiControlGet outputVar, Pos, ControlID) doesn't help! (could be a wish... if ControlID is omitted, behavior remains the same, compatibility isn't broken).

Good catch. That will be fixed in the next update.

Can you double-check that; it seems to work for me. For example:

GuiControlGet, CustomOutputVar, Pos, VarNameOfControl

Thanks.

My bad, I didn't even tried because it isn't clearly documented in the 'Pos' section, so I assumed there is only one syntax...
I know it is implicit from the generic syntax, but I suggest adding a line of explanation or of example to clarify this. Thanks.
