You're only running a single command, so why are you using a batch file and not running the command line that it's holding directly using the Process class?

I have tried to use like below but it is not working
process.start("c:\windows\microsoft.net\framework\v2.0.50727\regasm.exe /codebase " & chr(34) & my.application.info.directorypath & "RenameFeature.dll" & chr(34)
this gives an error
Please help on this

Tha'ts because you tried to launch the entire command line as the executeable and didn't supply an argument parameter. Read up on the Process class instead of guessing at things. You'll get alot farther, faster, if you know how it works and what the different overloads of the Start method are.
It should look like this:
Process.Start("C:\Windows\Microsoft.NET\Framework\v2.0.50727\regasm.exe", _
String.Format("/codebase ""{0}""", Path.Combine(My.Application.Info.DirectoryPath, "RenameFeature.dll")))

Hi,
i am binding a data grid using an openfiledialoge control, which read the columns from an excel that the user has chose. There are a lot of unwanted headers coming in the grid when it binds, so how can i remove or hide them. I want to display only those headers that i have added in the columns of the data grid. Requesting your help in this matter. Thank's in advance.....

If you have defined the columns in advance, it may be that you are somehow resetting the GridColumnStyles collection in your code instead of just assigning a new data source using SetDataBinding.
The need to optimize rises from a bad design.

Thanks for the help Mike, but i am not using setdatabinding. i am using oledb connection, i am using the default view of the data table. i doubt if it has something to do with the default view of data table. why i have this doubt is till i select an excel only those columns that i have defined are shown in the grid but once i select the excel then columns like table_name, data type, isnull(checkbox) etc are shown in the grid. I want to remove or hide these columns.

Hmm, SetDataBinding is a method for DataGrid class regardless where you get the data from (it could be oledb, file etc). DataView is a valid argument for SetDataBinding and if no columns are defined in the grid before binding is done, all the columns in DataView are shown. You can either loop them through and remove those not needed or define columns in forehand.
Perhaps if you could post the code where the problem is, it would be easier to see the cause.

Okay,
First thing: You are obviously using DataGridView, not DataGrid as your original post implied. For this reason my earlier replies are useless.
Second: In DataView, include only those columns you need to show, nothing else. This automatically solves the displaying problem for DataGridView
If you must have unnecessary columns in the DataGridView for some reason (there should be none), but you want to hide them, you can refer to those columns with the column name in DataView. For example: Me.dgvExcelColumn.Columns("NotNeededColumnName").Visible = False

Hi...
mmm....
no idea why not working for you dude,
try this.....
*******************************
Me.dgView.Columns.Remove("ColumnName")
*********************************
ALTERNATIVELY
instead of using a dataview
*****************************
Dim DataViewExcel As DataView
txtTempXls.Text = ofdExcelReader.FileName
DataViewExcel = FillDataSet()
*****************************
try using a datatable
*****************************
Dim DataViewExcel As new DataTable
txtTempXls.Text = ofdExcelReader.FileName
DataViewExcel = FillDataSet()
DataViewExcel.columns.remove("ColumnName")
*****************************************
thats all i can think of though....
the above works fine for me.....
anyway, hope you come right...i gotta go till tom.

Setting a column's visibility to false should have worked. Might want to re-check your code or when it is being executed. Probably a timing issue.
Any suggestions, ideas, or 'constructive criticism' are always welcome.

The best way to do this is to retrieve only the columns you need from the database. Outside of that, if you have a table that has more columns than you need to display, turn off the option that automatically creates columns in the DataGridView, then create your own DGV columns (which you should already be doing anyway, right?!), and map those columns to the ones in your DataTable.

Dave am using visual studio 2005 and am not able to find the property AutoGenarateColumns for the datagridview....can you help me on this.....thanks in advance...

Did you use the class name instead of the instance name?? This won't work:
DataGridView.AutoGenerateColumns
This does:
myDGV.AutoGenerateColumns = False
