I'm migrating DTS containing a Loop like:

    Pkg = DTSGlobalVariables.Parent;
    stpBegin = Pkg.Steps("DTSStep_DTSActiveScriptTask_1");
    stpBegin.ExecutionStatus = DTSStepExecStat_Waiting;

My needs are:
1: exec SQL Task 1
2: Script task 1(write log)
3: exec SQL Task 2
4: script task 1 again
5: exec SQL Task 3
6: script task 1 again
etc... etc...

How can I do this?

Following advice of MSDN user, I have implemented this solution:

I moved the script log task in the SSIS's event onPostExecute, I switched on tasks's property DisableEventHandlers.
If the single task don't have its onPostExecute event, the execution don't have problems and parent's event is fired regularly (1 time); Otherwise the event is passed to parent container and the event is fired 2 times.
So the sequence container also have DisableEventHandlers event disabled, but the parent event onPostExecute, is also fired

Someone known a work around for this behavior?
