RegRead @error Help

3 posts in this topic

#1 ·  Posted (edited)

Hello!

I've created a script that tests for a registry key and I want to check the @error value when it fails. I've tested this on a registry key that I know does not exist and the @error value still comes back as zero. Can someone offer some advice as to why or what I'm doing wrong! :)

Thanks!

$Log = FileOpen("C:\RegReadTest.txt", 9)
$RunOnceRegCheck = RegRead("HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce", "Test");Check to see if RunOnce registry entry exists.
MsgBox(0,"",$RunOnceRegCheck)
MsgBox(0,"",@error)
If $RunOnceRegCheck = "C:\Software\Test.exe" Then;Success
    FileWriteLine($Log, @YEAR & "/" & @MON & "/" & @MDAY & "-" & @HOUR & ":" & @MIN & ":" & @SEC & " RunOnce Registry key already exists." & @CRLF)
Else;Failure
    FileWriteLine($Log, @YEAR & "/" & @MON & "/" & @MDAY & "-" & @HOUR & ":" & @MIN & ":" & @SEC & " RunOnce Registry key DOES NOT exists." & @CRLF)
    If @error = 1 Then FileWriteLine($Log, @YEAR & "/" & @MON & "/" & @MDAY & "-" & @HOUR & ":" & @MIN & ":" & @SEC & " ...unable to open requested key." & @CRLF)
    If @error = 2 Then FileWriteLine($Log, @YEAR & "/" & @MON & "/" & @MDAY & "-" & @HOUR & ":" & @MIN & ":" & @SEC & " ...unable to open requested main key." & @CRLF)
    If @error = 3 Then FileWriteLine($Log, @YEAR & "/" & @MON & "/" & @MDAY & "-" & @HOUR & ":" & @MIN & ":" & @SEC & " ...unable to remote connect to the registry." & @CRLF)
    If @error = -1 Then FileWriteLine($Log, @YEAR & "/" & @MON & "/" & @MDAY & "-" & @HOUR & ":" & @MIN & ":" & @SEC & " ...unable to open requested value." & @CRLF)
    If @error = -2 Then FileWriteLine($Log, @YEAR & "/" & @MON & "/" & @MDAY & "-" & @HOUR & ":" & @MIN & ":" & @SEC & " ...value type not supported." & @CRLF)
EndIf
FileClose($Log)

I believe what is happening is that the message box is clearing the error,

when I try this code I get an error of -1 in the first message box, and a 0 in the second.

;~ $Log = FileOpen("C:\RegReadTest.txt", 9)
$RunOnceRegCheck = RegRead("HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce", "Test");Check to see if RunOnce registry entry exists.
MsgBox(0,"",$RunOnceRegCheck&'Error'&@error)
MsgBox(0,"",@error)

:) ...it was the FileWriteLine. Once I moved it down after the If @error statement, I was able to see the @error flag value.

Thank you for clearing the fog and pointing me in the right direction. :)
