Select Single Cell From Excel - Visual Basic .NET

PCK

I am trying to select a single cell from an Excel workbook. I am using the following code.

strCN = GetExcelConnect ion("C:\Test\Ex cel.xls")
strCMD = "select * from [Sheet1$A1:A1]"
oleDbCN = New OleDb.OleDbConn ection
oleDbCN.Connect ionString = strCN
oleDbCN.Open()
oleDbCMD = New OleDb.OleDbComm and
oleDbCMD.Connec tion = oleDbCN
oleDbCMD.Comman dType = CommandType.Tex t
oleDbCMD.Comman dText = strCMD
ds = New DataSet
oleDbDA = New OleDb.OleDbData Adapter(oleDbCM D)
oleDbDA.Fill(ds )
dt = ds.tables(0)

The table that is returned contains zero records. The name of the first column is the value from cell A1. Also if my SQL statement would have been "select * from [Sheet1$A1:A3]" then I would have got 2 rows returned with the value from A1 being the column name and the values from A2 and A3 being the two row values.

My question is how do I get the value of cell A1. Yes, I could get it from the column name, but surely that is not the best practice.

Do you have HDR=No in your connection string? It's probably using the first row/cell value as the
column name.

Problem with datagrid row select

by: Chris Plowman | last post by:

Hi all, I was wondering if anyone can help me with a really annoying problem I have been having. I made a derived datagrid class that will select the row when a user clicks anywhere on a cell (multi-select without modifier keys). I got that working fine, but I also wanted to keep rows selected after a sort, which I do by storing the row's id in an arraylist. The idea was to do the sort and then go back and re-select the rows with that...

For most users, this new feature is actually very convenient. If you want to control the update process,...
