RF-AutoIT: Cant upload files in Chrome - robotframework

Question

I am trying to create a common exe for 3 browser based file upload using below code.
IE (Choose File to Upload),
Chrome (Open),
Firefox (File Upload)
This is working for IE but not for Chrome and FireFox. There is no error but its not showing given file along with path.
I will be using this .exe in my Robot Framework script.
#include <MsgBoxConstants.au3>
SelectWindowBasedOnTitle()
Func SelectWindowBasedOnTitle()
$winList = WinList()
$wTitle = CheckWindows($winList)
IF $wTitle == "Choose File to Upload" Then
IE()
ElseIf $wTitle == "Open" Then
Chrome()
Else
FireFox()
EndIf
EndFunc
Func CheckWindows($aArray)
For $i = 1 To Ubound($aArray) - 1
If WinActive($aArray[$i][1]) Then $wTitle= $aArray[$i][0] ;MsgBox(0, "Window Check", $aArray[$i][0] & " is active.")
Next
Return $wTitle
EndFunc
Func Example()
$wText = WinGetText("[ACTIVE]")
EndFunc
Func IE()
ControlFocus("Choose File to Upload","","Edit1")
ControlSetText("Choose File to Upload","","Edit1",$CmdLine[1])
ControlClick("Choose File to Upload","","Button1")
EndFunc
Func Chrome()
ControlFocus("Open","","Edit1")
ControlSetText("Open","","Edit1",$CmdLine[1])
ControlClick("Open","","Button1")
EndFunc
Func FireFox()
ControlFocus("File Upload","","Edit1")
ControlSetText("File Upload","","Edit1",$CmdLine[1])
ControlClick("File Upload","","Button1")
EndFunc
This way i am using in my Robot script. Could you please help me understand is there a way to automate

${AutoIT} ${CURDIR}\\BrowserBasedWindowSelection.exe
Run Process ${AutoIT} ${FileInfo}
