Autohotkey – Want to launch program and bring it’s window to the front

^+i::
if WinExist("ahk_class Chrome_WindowImpl_0")
  {
  WinActivate
  ControlFocus, Chrome_AutocompleteEditView1
  }
else
  Run "C:\Users\vleeshue\AppData\Local\Google\Chrome\Application\chrome.exe"
return

Should do the trick

("Chrome_AutocompleteEditView1" is the name of the omnibar control, so you could add Send ^a to select all)

Note: To get the ahk_class for your version of Chrome, e.g., ahk_class Chrome_WindowImp1-0, use the AU3_Spy.exe inside the autohotkey directory. This will allow you to find the correct ahk class for your chrome browser if the example one doesn't work.

Update: I can't reproduce, maybe it will be better with another control... To have a list of a window controls I use this code:

#Persistent
SetTimer, WatchCursor, 100
return

WatchCursor:
  MouseGetPos, , , id, control
  WinGetTitle, title, ahk_id %id%
  WinGetClass, class, ahk_id %id%
  WinGet, ControlList, ControlList, A
  ToolTip, Under Cursor:`nahk_id: %id%`nahk_class: %class%`nTitle:%title%`nControl: %control%`n`nWindow Control List:`n%ControlList%
return

So the controls of my google chrome 4.0.249.78 beta (36714) are:

• ViewsTextfieldEdit1
• Chrome_RenderWidgetHostWND1
• Chrome_AutocompleteEditView1
• Chrome_WindowImpl_01
• Chrome_WindowImpl_02

I use the name only (since Google once changed the class name). Here is an expample in AHK_L that I use.

SetTitleMatchMode, 2

#ifWinActive, Chrome
    NumpadIns::Send, {Click}
    NumpadRight::Send, ^{PgDn} ; Right arrow = activate next Tab
    NumpadLeft::Send, ^{PgUp} ; Left arrow = activate previous tab
#ifWinActive
