I need a function to loop a macro until a field reaches 0 (1 Viewer)

[jconverse]

Thanks in advance!! I really have been out of VBA and Access for 5 years and have lost some of my edge. I need to loop a macro from a Function until a field in the Table [MakeRatio]![ASK] reaches 0. I can take care of the counting within the macro but I need to call a function from RUNCODE in a macro.

I'm confused, you want to loop a macro from a function or call a function from a macro? You can use DLookup() to check the table value in your loop and exit when it's 0.

Can you get me started on what it would look like?

Well, you haven't showed your code, so here's a guess:

If DLookup(...) = 0 Then
  Exit For
End If

That's some Inception level processing you want to undertake. Why not just do the whole thing in VBA?

As pbaldy mentioned--you haven't given us any code and you haven't really specificied what part of the coding is tripping you up. So, give it a shot yourself (even if its just pseudo-code), if it doesn't work then post code and ask us about specific lines of codes or methods.

Did you mean to say that you want to call this code inside of a SUB, rather than inside of a function? It would be kind of odd to call code from within a function, clearly not that it could never happen but it would be less common

A Sub is just a Function that doesn't return anything. Don't know why a sub would be more/less likely to do anything a function does.

I was wrong, there's another difference--you cannot call a Sub from a macro, but you can call a Function from a macro. But that just underscores that he definitely meant Function.

I definitely think it would be less common to call other code from within a function. Yes I'm quite aware of what a function and sub are. Anyway, we can wait till he clarifies
