[RESOLVED] Run time error 1004, can't figure it out

[Skitchen8]

So I'm nowhere near a professional VBA developer here, but I've done this before for working with huge spreadsheets at a previous job and didn't feel this dumb.

I keep getting the run time error 1004: Application-defined or object-defined error

and this is all I have:

Sub dosomething()

Sheet1.Activate
Sheet1.Visible = True
Sheet1.Select

Dim i As Integer
For i = 0 To 10 'Sheet1.Rows.Count
If Sheet1.Cells(i, 6) <> "" Then
Sheet1.Cells(1, 12) = Sheet1.Cells(1, 12) + Chr(13) + "duh = ListView1.ListItems.Add(,," + Sheet1.Cells(i, 1) + ")"
End If
Next i
End Sub

I've tried searching, but to no avail thus far. The only thing I came up with from searching was the first part, using activate visible and select, but that didn't fix it.

In case anyone is wondering, I have an excel sheet and I want to import all of the values into a multi-column listview in VB, which I have working but it is slow because it's opening the workbook to pull the values. I want to produce code to load the information in directly from my project so I don't have to have the additional excel workbook. I was testing my first few lines of code to make sure I remembered what I was doing, and have spent the last 30 minutes frustratingly searching for why this won't work. Please help

Thank you in advance,
Eric
