Comment MsgBox doesn't get any information

[i2i8]

I have a script  like this:

Local $GUID, $BootEntryName = "Test"

Local $sPid = Run('bcdedit /create /d ' & '"' & $BootEntryName & '"' & ' /application OSLOADER','','', $STDOUT_CHILD + $STDERR_CHILD)

If StringRegExp(StdoutRead($sPid), '(?i){',3) Then
    MsgBox(0,0,'Yes')
    $GUID = _StringBetween(StdoutRead($sPid), "{", "}")
    ConsoleWrite($GUID[0])
EndIf

In the code above, if I comment out the MsgBox , ConsoleWrite does not output any information. Why?

Maybe using ProcessWaitClose() before reading stdout will fix it.

Thank you so much, you are right, the final code is as follows:

Local $sPid = Run('bcdedit /create /d ' & '"' & $BootEntryName & '"' & ' /application OSLOADER','','', $STDOUT_CHILD + $STDERR_CHILD)

If StringRegExp(StdoutRead($sPid), '(?i){',3) Then
  ProcessWaitClose($sPid)
  $GUID = _StringBetween(StdoutRead($sPid), "{", "}")
EndIf

MsgBox(0,0,$GUID[0])

try the new and improved _RunWaitEx()   

now with "real code"  

PS: ..my head is full of jokes. I hope that the RunWait above get's it done.

Probably it would be even better if you place the line after Run() and before StringRegExp().
