Fail Build from VBScript

[modernrocketry]

I am using the tlbimp command in a build and have noticed that when an error occurs, the build continues.

So I cobbled together a vb script to parse the LASTSTEP_OUTPUT and look for an error (TlbImp : error)
Everything works as planned, except stopping the build if an error is found.

I thought "Step.BuildStatus = vbldStepStatFailed" would stop the set, but it reports succeeded and keeps going.
What am I doing wrong?

output = Split(Application.Macros(vbldMacroSystem)("LASTSTEP_OUTPUT"), vbCrLf)
For i = 0 To UBound(output)
    strSearchThis = output(i)
    if instr(strSearchThis, "TlbImp : error") > 0 then
         Builder.LogMessage "TLB ERROR FOUND"
         Step.BuildStatus = vbldStepStatFailed
         Exit for
    end if
    
Next

Where is the code, in the step's vbld_StepDone event? That should work (as long as 'Continue building' is not checked on the General tab). Please ZIP and send or post:
1) The info from Help | About | Install Info
2) A .bld file that reproduces the problem
3) A build log file

My error.
I had the above code inserted as a child step.
Once I moved it to the parent step in the correct event -- worked like a charm

Thanks for the quick turn around

I had a similar issue for a custom action.

Once I moved the code inside

Function vbld_BuildStep()

I was able to let the action fail by setting

vbld_BuildStep = vbldStepStatFailed
