How to detect if registry key is defined

[Ken]

I need to determine if a registry key is defined before I use it. If it's not defined, then I have to define it.

How do I go about detecting if a registry value is defined?

Use this in a Run Script step (VBScript):

Function RegValueExists(key)

Set objSh = CreateObject("WScript.Shell")

On Error Resume Next
objSh.RegRead(key)

RegValueExists = (Err = 0)

End Function

Builder.LogMessage RegValueExists("HKCU\Control Panel\Opened")

or put the function in project/global scripts and reference in a step field like

[RegValueExists("HKCU\Control Panel\Opened")]

When I tried this I get the following error. Any ideas on what I am doing wrong?

Error expanding macros in property condexpr: <Error at Line 1, Column 1 (Type mismatch: 'RegValueExists')>

The code I am using for the conditional execution is --

[RegValueExists("HKEY_LOCAL_MACHINE\SOFTWARE\Kinook Software\Visual Build Professional\Last Successful Build\%Project% %Unit%")]


The code from my global script is ----

Function RegValueExists(key)

Set objSh = CreateObject("WScript.Shell")

On Error Resume Next
objSh.RegRead(key)

RegValueExists = (Err = 0)

End Function

Based on the error message, it appears that the RegValueExists function is undefined. Did you add it to project or global scripts (View | Script Editor | Project/Global tab)?

OK, I see my mistake. I had placed it in the "Global Subroutines Steps" tabs and not the folder you told me. This fixed it! Thanks.
