If I use the following code it will create an input that will allow only "numbers". Is it possible to create my own style that would allow numbers & ".-"? I will be using it for Currency - example(3.50,-100.00) ----------------------------------------------------------------------------------------------------------------- #include <EditConstants.au3> #include <GUIConstants.au3> $Frm = GUICreate("Test Form",200,100,500,500) $Input = GUICtrlCreateInput("123",10,10,70,18
