Excel problem: Cant hide column.

[sorcerdon]

Hello experts,

I am currently opening an excel file from a VB.net application.
The excel spreadsheet gets all its data from a Dataset.
I need to hide a column form the results.
I dont want the users to have access to that perticular column in the
excel spreadsheet.

Here is my current code:

Dim dt As DataTable = dsSql.Tables("TableName")
Dim col As DataColumn
Dim mrow As DataRow
Dim objxl As Excel.Application
Dim objwbs As Excel.Workbooks
Dim objwb As Excel.Workbook
Dim objws As Excel.Worksheet
Dim colindex As Integer
Dim rowindex As Integer
objxl = New Excel.Application
objwbs = objxl.Workbooks
objwb = objwbs.Add
objws = CType(objwb.Worksheets(1), Excel.Worksheet)

If includeheader Then
For Each col In dt.Columns
colindex += 1
objws.Cells(1, colindex) = col.ColumnName
Next
rowindex = 1
Else
rowindex = 0
End If
For Each mrow In dt.Rows
rowindex += 1
colindex = 0
For Each col In dt.Columns
colindex += 1
objws.Cells(rowindex, colindex) =
mrow(col.ColumnName).ToString()
Next
Next

objxl.DisplayAlerts = False 'Makes overwrites automatic so that
a prompt to overwrite doesnt pop up
objwb.SaveAs(sFileName)
objwb.Close()
objxl.DisplayAlerts = True 'Makes overwrites non-automatic so
that a prompt to overwrite does pop up
objxl.Quit()
objws = Nothing
objwb = Nothing
objwbs = Nothing
objxl = Nothing


What is the code to delete ONE entire column and where do I place it?

The easiest way to find out code for excel is to fire up excel's Macro
recorder, do your task and then modify the generated code to your
needs.

Hope that helps,
