Checking Conditional In SSIS

I am converting a DTS package to SSIS.



DTS has the following steps:

1. SQL task that returns a variable ( a count ).

2. ActiveX script:

Function Main()

If DTSGlobalVariables("gsPrevProcessCount").Value > 0 Then
MsgBox "The data for one or more of your members has already been processed. Please review your data files and remove the processed files from the data directory."
Main = DTSTaskExecResult_Failure
Else
Main = DTSTaskExecResult_Success
End If

End Function



In SSIS, I have an Execute SQL Task that returns a variable PrevProcessedCount. Now, I am stuck. How do I display a message to the user (or maybe just put it in the audit log) and how to I check the variable and stop processing my package?
