dpaynebrown 0 Posted June 27, 2007 Share Posted June 27, 2007 I've had great success using the GUIRegisterMsg command on forms having a single Input control. When I attempt to do the same with multiple Input fields as shown here, I receive the following error from SciTE. ==> Variable used without being declared.: Case $txtBoxB Case ^ ERROR The code in the MessageHandler function doesn't do anything but display a MsgBox for this example, but I can't get it to even run. Furthermore, commenting-out any one of the (3) Case statements results in the same error message but referring to one of the other fields. So, what am I missing? expandcollapse popup#include <GUIConstants.au3> #include <Misc.au3> #include <Array.au3> #include <GuiEdit.au3> _Singleton( @ScriptName ) Global $TESTING = True ;- Initialize general variables Global $i, $j, $k, $x, $y, $z ;- Temporary variables (some may not be used) Global $gvEvent ;- Define Windows notification messages for an editbox.

Siao 7 Posted June 27, 2007 Share Posted June 27, 2007 (edited) GUIRegisterMsg( $WM_COMMAND, "_MessageHandler" ) in your code is set before you actually create the controls (and initialize those variables with controlIDs) , so it's not surprising that it complains about $txtBoxB or whatever being undeclared...
