ShellExecute("C:\Users\drake\Desktop\toggle.lnk")
Local $hw = WinWait("toggle", "", 2)
Local $result = ControlSend($hw, "", "TEdit2", "sewsfd")
MsgBox($MB_OK, "", $result)
WinClose($hw) 

why do i get return value "0" of the controlsend function?

1. You get return value of 1 because the function failed.

2. Don't know you code is a bit vague.

try that

Local $hw = WinWait("toggle", "")

[somdcomputerguy]

From the Help file / ControlSend

Success: 1.

Failure: 0 if window/control is not found.

pay attention to the cause of return code 0. Edited April 10, 2014 by somdcomputerguy

There are too many potential fail points for us to speculate, especially because there is no error checking, except for when you output the $result...do it like this, so you know what's wrong...it's more code, but explicit...there are still some check steps you should do, like waiting for the window to be a state of enabled, verifing the control is enabled, etc:

$bContinue = ShellExecute("C:\Users\drake\Desktop\toggle.lnk")
If $bContinue Then
    ConsoleWrite("Shell execute returned true")
Else
    ConsoleWrite("Shell execute returned false")
EndIf

If $bContinue Then
    Local $hw = WinWait("toggle", "", 2)
    If IsHWnd($hw) Then
        ConsoleWrite("Able to find toggle window handle")
    Else
        ConsoleWrite("Unable to find toggle window handle")
        $bContinue = False
    EndIf
EndIf

If $bContinue Then
    Local $hc = ControlGetHandle("toggle", "", "TEdit2")
    If IsHWnd($hc) Then
        ConsoleWrite("Able to find TEdit2 control handle")
    Else
        ConsoleWrite("Unable to find TEdit2 control handle")
        $bContinue = False
    EndIf
EndIf

If $bContinue Then
    If ControlSend($hw, "", $hc, "sewsfd") Then
        ConsoleWrite("Able to send sewsfd")
    Else
        ConsoleWrite("Unable to send sewsfd")
        $bContinue = False
    EndIf
EndIf

edit: wrong number of nested endif's
