Excel vba create two dimension array and populate range with data
All,
I know there are pitfalls of using the ADO object model, however, in the preceding example, it is the only way I see possible to achieve my needs.
In short, I am using ADO to query a table (dynamic range) called tbl_cashbook. I group each code and sum the values of each code based on the parameters of a start and finish date as well as a name.
What I need to do is to collect all this data into an array and then populate the values into a predefined range in my workbook. My array should contain 2 fields, Code and Value.
That said, I enclose the following code as my starting point and seek some guidance as to how I can: 1). create the array, and 2). populate the array into my worksheet range.
Any help appreciated.

End With
End Sub
Any help appreciated.

Would be helpful if you upload this excel file (fill with dummy data), and then give a few example inputs and expected output.

Okay. Here we go.. I have put together a small example of what I seek to achieve from this.
Please keep in mind that the data set is dynamic and that there are many other code routines that require consideration as well.

Hi. Thanks for getting back to me.
The answer to your question about using the array later in my code is a NO.
I agree that it would be better to use your method by writing the records directly to the worksheet as opposed to storing an array. I thought there must be an easier way and you have confirmed that with me.
I shall try out your code and post an update when finished. Hopefully it works out as I really need to complete this in order to move on with my work.
