Question

I’m working on converting an Excel VBA project to a VB.net Office Solution. In VBA accessing a named range within a sheet was pretty easy.
Sheet1.Range(“NamedRange”)
would give you the value in that cell.

In VB.net I’ve tried several different things, all ending in failure.

I started here. http://msdn.microsoft.com/en-us/library/aa168292(v=office.11).aspx#excelobj_link9

I’m using one of the Visual Studio Excel 2010 Document template, and I managed to set a value in a named range on a sheet. The template creates a class for each tab on the worksheet, so I was able to do this.

Me.Range("A5").Value

What I’m having trouble with is how to access a range on a worksheet, in particular I can’t figure out what objects I need to create before I can access a worksheet. The following is what does not work:)

Public Sub GetInputs()
    Dim XlSheet1 As Excel.Worksheets
    Xlval = XlSheet1("Sheet1").Range("NamedRange").Value

This leaves me with null reference… I’ve tried several other things and gotten several other errors. Any push in the correct direction would be much appreciated.

The following code compiles and runs in a separate code module. The key is using the Globals object to access the Excel application objects:

Dim xlWorksheet As Excel.Worksheet
Dim xlNamedRange As Excel.Range
Dim xlVal As Object

xlWorksheet = Globals.ThisWorkbook.Worksheets("Sheet1")
xlNamedRange = xlWorksheet.Range("NamedRange")
xlVal = xlNamedRange.Value
MessageBox.Show(xlVal)
