This is the problem with concantenating string together. Like Christian pointed out, you're missing a space between the ")" and "values" in your resulting string, which looks something like this:
insert into Branch ([BranchN Name])values (@branchname)
which, in SQL, is a problem. There must be a space just before "values".

Your other issue is this line. You might want to try validating the entered text AND convert it to an Integer before you try and assign it to the parameter value.
Dim branchId As Integer
If Integer.TryParse(tb_branch_id.Text, branchId) Then
' Create your parameter object and assign the value of
' branchId to it's Value property.
' Then you can do your query
End If
If the TryParse statement returns False, the text entered could not be converted to an Integer, invalidating your SQL lookup.

Hi,
using VB .NET 2005, we have a ListView control and sometimes when there is no space left, scrollbars appears. What we need to do is to change the color of the scrollbars. For example to make them red. Any idea on how to do that ?

There are no properties for the scrollbars in the standard controls. They render themselves using the colors define in the Display Properties control panel, under the Appearance tab.
You can replace the control's scrollbar with your own custom implementation, but is it really worth it??[^]

This means that you're trying to use an object that your code assumed it either created or retrieved sucessfully. You're trying to do something like this:
Nothing.SomeMethod()
or
Nothing.SomeProperty = someValue
You can use a Nothing object...

Thank you Dave ..
But the problem is...............
I put validations(required field validators) for all the textbox....
when i click submit button......
its giving this error...
the first thing it should do is validations ......
and the first statement in the button submit event is page.validate()
but still it gives this error
"System.NullReferenceException: Object reference not set to an instance of an object."
Please help me
i'm not familiar with this

Well, are you handling any of the Validation events? Something in that code is assuming something it shouldn't be.

text.Visible = True
text.Name = "text" & CStr(xCnt)
text.Location = New Point(122 + (3 * xPnt), 135)
text.Size = New Size(60, 21)
text.MaxLength = rd.Item(0)
xCnt += 1

may be you can access these textboxes like normal textboxes
the only difference between the two is that one is putted at designtime and another at runtime

In this line you're already giving textbox a name and to get a data of that text box just use that name, it's simple.
E.g.
dim txtVal as string = textxCnt.text
this should do it i guess...

OK, sounds like an issue in your AVI.

Either the AVI is currupted or you don't have the appropriate video codecs to decode the video stream.
