Looping through tasks

[Puck312]

I am trying to loop through the tasks in two Project 2007 files which contains subprojects. I am using the same vba routine (from Excel) similar to below:

For Each tsk In proj.Tasks 
    blah 
    blah 
    blah 
Next tsk 
 
For Each subproj In proj.Subprojects 
    For Each tsk In proj.Tasks 
        blah 
        blah 
        blah 
    Next tsk 
Next subproj

When looping through one one of the files, the first For-Loop grabs all tasks of the master project AND all the tasks of each subproject. When looping through the other file, the first For-Loop only grabs the tasks of the master project, and I need to loop through the tasks of the subprojects seperately using the second set of nested for-loops.

Does anyone know why this would happen?

I can handle either case individually, but don't know beforehand which will happen. I cannot be sure that the master project only contains subprojects and no 'live' tasks of its own. So, I have to loop through the master project's tasks, and I don't want to read the subproject tasks a second time by looping through each subproject if I don't need to.

Thanks!
