Execution Order

[Ricky W. Hunt]

VB.NET seems to be processing things in a different "order" than I'm used
to. For example, I had a problem (I don't have the exact code handy anymore
so it's just a "guess") where if I put the complete code in a single
subroutine it wouldn't work but if I put the part that wasn't working in a
subroutine, and called it after the first subroutine finished, would work
even though if you laid out the actual commands linearly ("in order") they
would be exactly the same. Does anyone know why this happens and what is it
"called"?

Normally, this should not occur. I can imagine some situations where
placing code in a separate procedure and calling this procedure may
behave differently because of a possible small delay caused by the call
to the method, but in general, there must not be a difference.

That was my guess too. So I tried putting a Sleep command (up to 5 seconds -
5000ms) and it still didn't work. Only when I put it another block did it
work. I will try to come up with the exact code again and post it to see if
you have any clues. BTW, thanks for all the help you provide.

Are you reusing a variable name in the subroutine whic when the code is
linear alters its operation ? Just a guess.

OK, I think it doesn't make much sense to discuss this topic without the
source code that caused the problem.

No. It's just a call to the Window's Media Player. No variables involved at
all
