i am using VB.net for the first time on a data project. I have used the built in functions to put data in a DataGrid. Now what I need to know how to do is when user types in a text box use that to narrow results.
Any examples or help is appreciated.

Hi,
I have to select the value in datagrid and get that selected value in textboxes and update and delete the values from the textboxes.Please tell me how can i do this in vb.net 2003.

How do you mean 'select the value'. You want to search for a value ?
You want to update and delete what ? The grid, or the data source ?

http://www.codeproject.com/cs/database/gridex.asp[^] looks helpful. You could either use the control, or look through the code to see how it works.
Depending on your datasource, you may be able to run SQL on the source, or you can iterate over the Rows collection to find the values you need.

hi thanx for the link...i had a look it seems to be done in C. I have done it in vb code. i used the wizard to create the forms. Using a untyped dataset i think. all the search code ive found is for typed datasets i think...
Me.objdsDiary.Clear()
Me.OleDbDataAdapter1.SelectCommand.CommandText = "Select * from 0830 where AppointmentDate like '%" & Trim(Me.lbl2.Text) & "%'"
Me.OleDbDataAdapter1.Fill(Me.objdsDiary)
or
Adodc1.RecordSource = "Select * from secretary where club = """ & txtSearch.Text & """"
Adodc1.Refresh
or
Private Sub Command1_Click()
With Adodc1
.Recordset.Find "Au_Id=" & CInt(txtAuthorId.Text)
End With
End Sub
which do not work as i dont have adodc, all i have is CottageBookingSystemDataSet, TblEmployeeBindingSource, TblEmployeeTableAdapter, TblEmployeeBindingNavigator.
Ive been looking on so many forums.

i have found the code to search using a string,
TblCustomerBindingSource.Filter = "txtFirstName LIKE '%" & TextBox1.Text & "%'"
how to i implement it to search a int eg the primary key for customerid?

You don't know how SQL works ? It's pretty simple, and there are tons of examples on the web. At it's most basic level, select * from [tablename] will return all the data in a table, and select 8 from [tablename] where [column] = [value] ( with single quotes around strings ) will select a particular value.

OK, you're connecting to a text file ? What does that have to do with SQL ?

From a textfile ? Is that even possible ? Your textfile doesn't have any named columns, if some sort of reading of textfiles is possible, I doubt it's using SQL.

hello
how can i delete subfolders within a folder

The same way you delete a folder, one at a time. YOu need to iterate over sub files and folders before you can delete a folder.

How can i Unzip the zip files using vb.net code...
Feroze

I think VB2005 has a zip library, any other version, you need an external library

if u have installed winzip on ur machine and if it allows u zip/unzip at command prompt then u can do it easily....
1) create a process by specifing executable path of winzip.exe...
2) specify other parameters i.e. files to zip/unzip with required switches...
3) run this process...
Thanks & Regards...

Hello everybody!
This may sound like a really stupid question, but let me tell you that i'm new to .Net, so please be patient with me!
I need to find out what is the equivalent of the .additem function from VB in .Net.
Thank you sooo much!

That depends, what does it do ? Is it a method on a control ? If so, the controls have Items collections, so it becomes Items.Add.
