Re: Need advice with WshNetwork PLEASE Trey549822-Oct-08 5:05 Trey5498 22-Oct-08 5:05  It installed the printer, however it did not create or even use the LPR port. Please how do I direct the driver to a server side .inf file? and it does seem to work in the BG worker Re: Need advice with WshNetwork PLEASE Dave Kreskowiak22-Oct-08 6:37 Dave Kreskowiak 22-Oct-08 6:37  Then you're going to have to use WMI to create the connection. It appears that the documentation is correct and the port parameter is ignored on NT/2000 kernel systems. I don't know the exact process to go through, but you can do the research on it by reading up on the WMI class "Win32_Printer".

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"))) A guide to posting questions on CodeProject[^] Dave Kreskowiak Microsoft MVP Visual Developer - Visual Basic      2006, 2007, 2008 Re: Need Help on Custom Action Installer Saseendran Kombath23-Oct-08 4:15 Saseendran Kombath 23-Oct-08 4:15  Thanks a lot Saseendran Kombath How do remove unwanted coulmns from a data grid? Arun Philip R21-Oct-08 8:09 Arun Philip R 21-Oct-08 8:09  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..... Re: How do remove unwanted coulmns from a data grid? Wendelius21-Oct-08 8:28 Wendelius 21-Oct-08 8:28  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. My articles[^] Re: How do remove unwanted coulmns from a data grid? Arun Philip R21-Oct-08 8:41 Arun Philip R 21-Oct-08 8:41  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. Re: How do remove unwanted coulmns from a data grid? Wendelius21-Oct-08 8:50 Wendelius 21-Oct-08 8:50  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.

Wendelius22-Oct-08 7:36 Wendelius 22-Oct-08 7:36  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 The need to optimize rises from a bad design. My articles[^] Re: How do remove unwanted coulmns from a data grid?

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.
