Question

I have a sub (macro) in Excel that I want to be able to call from Access, which looks like this:

Sub myMacro(param1 as string, param2 as string)
...
End Sub

In Access, I have:

xlBook.Application.Run "myMacro", string1, string2

But I get the error :

Runtime Error 450:

Wrong number of arguments or invaluid property assignment

How do I pass multiple parameter to Excel?

Answer 1

As per @Remou’s comment, I checked the variable types being passed.

In this case, string2 was a Variant that was supposed to hold a String of numbers, but when the string of numbers got stored in string2 (the Variant), it was converted to a number (stored within a variant [?]).

Nonetheless, stricter (and thus correct) type declarations solved the issue.
