Question

Excel macro runs twice instead of once

Asked by: PaultheGreat

This is a link to my previous question to which I have not received a suitable answer:

http://www.experts-exchange.com/Applications/MS_Office/Q_20666870.html

I'm looking for the reason why this happens and/or what can be done about it aside from what was mentioned in the previous question.

Thanks!

Presumably you have debugged the macro and you know when it fires a second time. When does the second run happen and what is different during the second run that stops it running a third time?

Do you have any events that are triggerred when the macro runs? If you do then throw in an Application.Events = False at the start of the macro to disable the events but remember to reenable them at the end of your code.

Cheers

Dave

This really seems to be a bug in Excel 97, because even if I just have a simple msgbox in the sub it's called twice.

I noticed this one only happening when you use a macro that has a parameter. I don't think you are supposed to use a sub with a parameter in a toolbar (as this is not really necessary, because the parameter won't change itself anyway, and, hey, they aren't even listed there).

So why don't create some "call-subs". For each button, assign it's on sub that calls you main sub with the appropriate parameter.

Sub Button1
  MyMacro (1)
End Sub

Sub Button2
 MyMacro (2)
End Sub
...

By the way, I did not find any bugfix for this one and I guess that's just because there is none. (I don't think that many people really need this

brettdj,
When I was first trying this out, I had simply one line of code that was executed to modify a cell when the user pressed the button on the toolbar. I tried setting Application.Events to False but that had no effect; no events should be triggering that would cause the toolbar button to be "clicked" again... oh, and btw: even if I set breakpoints, they aren't hit. The code just activates twice and that's that.

Steiner,
That's what I was thinking, but I was hoping there was a different answer. Yes, I had noticed that my Public Sub with(parameter) wasn't listed in the macro selection thingy... I just thought I'd still be able to run it normally. The "call-subs" really wouldn't work out for me, since there are a bunch of buttons all trying to call just one or two lines of code... I'd be changing a couple lines of code into about twenty or thirty like that, and I like to be able to keep things dynamic (e.g., I could add a button to the toolbar at any time and simply give it a different paramter in the OnAction property whereas I'd have to hard-code all the "call-subs" for every possible parameter I'd want to use. Grr... M$...

If you have something you want to add, brettdj, that perhaps I missed, go ahead... if no one posts by late afternoon I'll probably just give the points to Steiner. Btw, Steiner, I was thinking of giving you a B since you didn't really give me any documentation or anything (which you can still do, if you can find anything) that talks about subs with parameters that would help support any statements. If you think that's unfair, certainly let me know. And post in the other thread so I can give you those points as well.

Thanks,
PtG

>since you didn't really give me any documentation or anything ... about subs with parameters that would help support any statements

What documentation do you think of here? A general documentation of subs with parameters can be found in the VBA-Help (select Sub and press F1).
And since it seems that using subs with params on a toolbar-button is not supposed to work, there won't be too much documentation about that around (at least none I could find). Or what kind of documentation did you have in mind?

One other way for your problem could be to use the ActionControl-property. But this one was already suggested by Suat in the other thread. Even if you can't really use his answer, it's not his fault that MS created bullshit.

So I'd think that you give him the points for the thread he posted in (or ask for a refund if you REALLY NEED these question points) along with some finishing comment so he knows what it's all about (I can't believe I'm advising to give points to someone else instead of me, guess I should visit a doctor ;-))

If I come up with another solution in the next time, I'll post it here.
