First, it's better to organize your code and make it readable :)


con = New OleDbConnection(constr)
adpt = New OleDbDataAdapter("select * from drs_entry_list where drsno='" +...

This example code explains maybe :=)


Dim _DT As DataTable = Nothing

Private Sub Form2_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
_DT = New...

At which point it generates that error? If the index is out of range you're trying to get a non existing row in the collection of rows......

Could you show some code?

Regards

If you don't want the blank row to be shown you have to set the 'enable adding' property in the designtime to be false.

Try this


Private Sub DataGridView1_KeyUp(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles DataGridView1.KeyUp
If Keys.Enter Then
Dim _Dt...

*only for your attention*

I guess you should also check the TextFieldParser object :=)

Ossehaas,

Check the StreamingContext class for additional info.... I think it will help ya out....

According MSDN:


Imports System

Dim newRow as DataRow = yourDatagrid.newrow()

newRow.Item(0) = "yourText"
etc. etc. etc.

yourDatagrid.rows.add(newRow)

Can you tell us what happens before we have to puzzle?

(think about getting your car back to the shop & ask the technician if he can tell you what's wrong with your car?)

Why not storing them in a List(Of String)?


Dim listOfNames As New List(Of String)

Private Sub Button1_Click(ByVal sender As System.Object, _
ByVal e As...

No sorry, it's time to find out yourself....
I coded an example and added comments to it, so you know what steps to take.

Now it's up to you.......

Okay, here it is :


Private Sub cmdSearch_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles cmdSearch.Click

'variabeles (objects and strings)
Dim _root As...

An excellent resource for you is : http://www.startvbdotnet.com/

Like Jx_Man says.... use that condition in your select statement. For example like this : SELECT * from UMP WHERE ID = yourID -> 'yourID' is the ID which you are looking for.

A better approach is...

First, try it in the same sub/function. If it works you can export the functionality to some global functions/subs

try this:

Try
strCon = "provider=SQLOLEDB;User id=" & U &...

At least you are pointing to the right directions at this moment. The questions you ask seem to me you are now in the right 'developer-mode' :=)

There are a few options but one of the simplest is to detach the database from the server, copy the phisical files to the new dataserver's datapath and attach it to the new dataserver.

For those...

You must have 2 parameters declared in your Stored Procedure, called @DR and @CR, both of the type Decimal.

Aha, this points out the way you think.
Yes, there are so many solutions in solving a problem in VB.Net. You can still use some good'old VB6 syntax. The designers of .Net, esspecially VB, didn't...

To help you a little more:

You also can add a ContextMenuStrip to your solution and respond on the rightclicking of a user into one of the columns in your datagrid.
For example, if the user...

Something like this?
It will expand the last column in the datagridview. You can edit it to your needs :=)


Private Sub DataGridView1_DataBindingComplete(ByVal sender As Object, ByVal e As...

Hehehe..... absolutely no hard feelings :=)
I am glad you figured out the databinding issue.

Binding can be done on tons of different ways, even runtime. You have to find the way which you are...

Rapture,

Thank you for your clarifying words. What you describe is exactly what I was thinking about. Exclamation points are a real pain in the *** sometimes but they do give some expression to...

Euhh..... insulting your intelligence? Excuse me, that's not what i intended to mention.

Lets start over again. You are trying to view some table-data in a datagrid in a "windows application"....

Databind() is a function which needs to be called when binding data to a datagrid in ASP.NET !

Only use datasource when binding in Windows.Forms solutions!

yourGrid.DataSource = yourDataSource...

I really don't understand a thing about your question!

If you are asking for some help you really need to explain everything into details. We can't guess about what your goals are.....

Have you ever checked the Date options?

date.Day, date.Month, date.Year etc etc etc

Try to find the Table, TableRow, TableCells OR Fields with yourPage.FindControl("")
If the control will be found the value can be added to it. As jbennet says, the code didn't change thát much.......

Google will be your friend ;)

hmmm..... Shouldn't thé approach be : only insert a warranty-card-number into the database after a check if the card-number already exists?
You could write a stored procedure for example in which...

It should work with the fields.add() like you mentioned before. Did you also checked if your firewall blocks ports 25? If so, port 2525 might do the job....

Okay, just for asking.....

Check this site, it's a good reference for programming-help. Try the simple example and if that works, extend it piece by piece.
Let me know if it worked....
