Fubarable Posted October 12, 2009 Share Posted October 12, 2009 (edited) Hello from a new user of AutoIt. Please help me straighten out a small bit of confusion about the correct parameters used for calling the GUICtrlSetData function. I am learning about combo controls and how to fill them with data using GUICtrlSetData, and I notice in the online documentation for GUICtrlSetData it states that the first parameter should be the control identifier of component that is receiving the items to be added, however in the example shown, and in many posts in this forum a parameter of -1 is often used. Why the discrepancy? Is there other documentation that I have missed?Many thanks in advance!Pete Edited October 12, 2009 by Fubarable Link to comment Share on other sites More sharing options...
water Posted October 12, 2009 Share Posted October 12, 2009 -1 means the last used control. It just makes the code a bit shorter.

GEOSoft Posted October 12, 2009 Share Posted October 12, 2009 Experience has also taught me to only use -1 on controls that have not been declared as a variable, otherwise use the variable name instead. This works fine. GUICtrlCreateLabel() GUICtrlSetColor(-1, 0x000000) This works $label = GUICtrlCreateLabel() GUICtrlSetColor(-1, 0x000000) This is better $label = GUICtrlCreateLabel() GUICtrlSetColor($label, 0x000000) George Question about decompiling code? Read the decompiling FAQ and don't bother posting the question in the forums.Be sure to read and follow the forum rules. -AKA the AutoIt Reading and Comprehension Skills test.*** The PCRE (Regular Expression) ToolKit for AutoIT - (Updated Oct 20, 2011 ver:3.0.1.13) - Please update your current version before filing any bug reports.
