Invalid Qualifier for String.Add in Outlook VBA - arrays

Question

You all have been so helpful, and I was wondering whether I might trouble you a bit more. I have nearly completed my conversion from VB.net to VBA for Outlook, and in order to complete that, I need some information on what exactly a particular piece of code is returning. If you all can help out with that, the problem may go away; if not, I might need some help on this invalid qualifier error.
From what I understand, I declare an 'array' in VBA with a command like this:
Dim Computers(1, 1) As String
Which produces a 2x2 array. I then try to fill it like this:
Computers.Add ComputerName, ErrorState
where ComputerName and ErrorState are variables which I have already filled. This results in the error. I will provide you with the entire relevant section below. I need to know how many relevant items are in the outlook inbox, which means checking if they were sent on today's date and by the correct sender. I need this in order to get the correct dimensions on the array Computers. (The array is filled in right now as I know the correct dimensions, but in practise I will not.) I took a piece of code which I found through google, the Scripting Dictionary output, but I do not fully understand it. I need just the number of emails, without any irrelevant text, and I was hoping that the debug line would be able to tell me which command I would need to return the number and nothing else. Unfortunately, because of the above error, I cannot get to this line. Even by stepping through the code, the very first thing it tells me is that there is a problem here. The entire relevant section is below. I know that the formatting is problematic, but I have only been working with VB.NET for 4 days, and this is my second day of working with VBA, so I do not quite have everything down yet. There's some irrelevant stuff in here, I'm pretty sure, but I do not have the experience to make the call of whether something is relevant or not, so I left it all. Sorry for the length!

This website has been incredibly helpful as not only a place for me to ask questions but also as a place for me to find relevant information without having to trouble you all. Unfortunately, it is all too often that I do have to trouble you all, but every time you have been very kind and helpful. And I would like to thank you for that.

Answer 1

you're trying to use the Add() method from a Collection to assign an element in an array. To assign an element in a 2-D array you'd use arr(a,b)=someValue where a and b are numeric values. – Tim Williams
