Ensure you have the SQL server configured properly, user/group permissions, and check the *firewall* on the server and client.
Any suggestions, ideas, or 'constructive criticism' are always welcome.

The values in the datagrid for each row are like this:
1,joseph, 5thclass, B, true, false, true, true, etc depending on the selection.
How to insert multiple records into a database table that are entered into a datagridview. With a single shot of Save all the records in the datagridview should be inserted in new table using Vb.Net . Can any one help me in this regard.
Any help appreciated

At first you declare a Datatable Then Innsert Your Data into that DataTable and at last Set DataGridView.dataSource=Datatable

I am trying to create a VBScript which will accomplish the following:
1. Run ONLY if it's within an IP Address range
2. If it is, run Robocopy to copy Documents and Settings to a network share
3. The destination folder is the user name used to log into the PC
4. Run at a certain time of the day
Any help is greatly appreciated...

Isn't TDBGrid a Delphi control?

Hi all I just have a question about the report progress on my background worker. Can anyone tell me what I am doing wrong with this code.
The problem I am having is the result window textbox2.text from my Sub BackgroundWorker3_ProgressChanged only shows some of the stream the last part of the stream is not displayed so I am guessing I am missing something to display the rest of the stream?
<code>
'Start NSLOOKUP
Private Sub NSLookupToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles NSLookupToolStripMenuItem.Click
With Me.BackgroundWorker3
ToolStripStatusLabel1.Visible = True
ToolStripProgressBar1.Visible = True
ToolStripProgressBar1.Style = ProgressBarStyle.Marquee
Me.Cursor = Cursors.WaitCursor
.WorkerReportsProgress = True
.RunWorkerAsync()
End With
End Sub
'Start Do Work process
Private Sub BackgroundWorker3_DoWork(ByVal sender As Object, ByVal e As System.ComponentModel.DoWorkEventArgs) Handles BackgroundWorker3.DoWork
Dim lookup As Process
lookup = New Process
With lookup
.StartInfo.FileName = "nslookup"
.StartInfo.Arguments = TextBox1.Text
.StartInfo.UseShellExecute = False
.StartInfo.CreateNoWindow = True
.StartInfo.RedirectStandardOutput = True
lookup.Start()
Dim outputReader As StreamReader = .StandardOutput
outputReader.ReadToEnd()
Do While Not outputReader.EndOfStream
Loop
BackgroundWorker3.ReportProgress(1, outputReader.ReadLine)
End With
End Sub
'Start Progess of Process/Stream Output
Private Sub BackgroundWorker3_ProgressChanged(ByVal sender As Object, ByVal e As System.ComponentModel.ProgressChangedEventArgs) Handles BackgroundWorker3.ProgressChanged
TextBox2.Text = e.UserState.ToString
End Sub
'End BGW
Private Sub BackgroundWorker3_RunWorkerCompleted(ByVal sender As Object, ByVal e As System.ComponentModel.RunWorkerCompletedEventArgs) Handles BackgroundWorker3.RunWorkerCompleted
Me.Cursor = Cursors.Default
ToolStripStatusLabel1.Visible = False
ToolStripProgressBar1.Visible = False
MsgBox("NSLookup Complete")
End Sub

This is nonsense. ReadToEnd() reads everything, and returns it as a string, which you ignore.
Then you loop for the end, which you already reached. Then you read a line, which isn't there.
I suggest:
1. you read the documentation on StreamReader class
2. clean up your code
3. when problems exist, publish your code using the "code block" button (i.e. PRE tags) so it is formatted and readable.

Thanks for the tips this is my first project using vb 2008 express I apologize in advance for not understanding the whole process yet, I will do some more reading on the stream reader.

Or any one can tell,how can we show limited number of rows in datagrids
is urgent thanks!

If it really is urgent, why didn't you google for an answer? There are several hits sitting there waiting for you?
If something is really urgent, I wouldn't post here where I would be waiting for someone to find the time/interest to give me an answer.
I would only post here after I'd searched the interweb and found nothing, and I'd say that in the post so that people would know I was serious.

Good Day parkash_C
Easy dont Fight. In this Forum you are not allowed to use words like Urgent. Because the people here they are not getting paid to help you you have to be patient and wait for them to answer you , and there more politely you ask the faster they asnwer you. It is encouraged that people should first make their own research before the post a question.
I went to google and i found plenty of examples like this

thanks for the help,
i ll keep your instructions in mind.
i tried finding it , i learned about web application
but couldn't find for windows....

But you did ask. You asked every CP member.
If you had said that you had googled and found nothing, that would be a different story, but as others have pointed out there are loads of suitable answers on the web.
If you had tried to use one of those solutions and got stuck whilst doing so, you would have almost certainly got lots of help.
On the other hand, if it appears that someone is not capable of doing basic research first, they should not expect help.
I really do hope that you find one of the links suggested by others useful, and solve your problem.
But google is your best friend in situations like this.
Good luck!

i am a starter dear ,it takes me time to understand
i never search code, i look for proper function
they enhance your logic
i was looking for a datagrid property or function,like in web forms
which i dont thing exist, if there is do tell me 
|
|
|
|

AFAIK there is no property or function in the datagrid control to allow paging (by the way is it a DataGrid or a DataGridView? It makes no difference in this case, but it probably will if you have othter problems).
There are lots of different ways to do it, so have a look at the links given by others to see if there is something that can help you, or at least give you some ideas to implement your own solution.

when press button in flash talk to vb to show certain form
|
|
|
|

AFAIK, Flash has no methods of communication to notify its host of anything happening.
In other words, there's no way for your code to know a button has been clicked in a Flash window.

This is not a question. Try posting something that is, and that includes what you did to try to solve your issue.
