Run Program, Resize it, Relocate it

My work often changes. I could be doing programming, then systems administration, then quality assurance. I often have to change from different toolset to toolset and I find it annoying sometimes having to rerun programs and moving them to the same locations. Then resizing. Eech. This is especially frustrating when I’m doing testing and I have to debug and read requirements all at the same time. One handy thing to do is to use AutoHotkey, the great scripting tool.

Here’s a handy script I put together that opens up two different programs, moves them on the screen and resizes the Window. Just copy and paste the same block of code for each program to open as may apps as you want with whatever on-screen configuration you want.

; Run Note.exe
; WinMove, WindowTitle, WindowText, X-Axis, Y-Axis, [, Width, Height]
Run, note.exe
WinWait, Untitled - Notepad2
WinGetPos,,, Width, Height, Untitled - Notepad2
WinMove, Untitled - Notepad2,, 500, 500, 200, 200

; Run your browser with the following URL
WinWait, tigers - Google Search - Mozilla Firefox
WinGetPos,,, Width, Height, tigers - Google Search - Mozilla Firefox
WinMove, tigers - Google Search - Mozilla Firefox,, 900, 200, 300, 400
