I am trying to get used to with automated data ui generation tools in vs2005. I generated an input ui just by dragging detailed view of an table from data sources pane. It created binded sources and even a navigator for data source. everything is fine up to here but i just dont like the names of controls generated. is it possible to change naming style of these auto generated controls automatically?
for example: FirstNameTextBox -> txtFirstName

Nope, not as far as I know.
Some third party add on tools DO allow you some level of customization to the emitted code they create though, that's what makes them more attractive than using the 'free' stuff included in the IDE.

Dundas has a charting library that would probably be the easiest way for you to achieve this task.

Hi everyone
Im using VB.Net 2003. I have a field in a datagrid "Total", how do i calculate the total and Display it in a label
|
|
|
|
|
I would suggest enumerating all rows of the datasource (datatable) and summing up each value from the target column.
It would look something like this:
(assuming there is a DataTable already created called DT
<pre>
Dim Total As Double = 0#
For Each R As DataRow In DT.Rows
Total += R(1) 'This line simply adds the value from Column 1 of the current row.
Next
Me.label1.Text = Total.ToString() 'Set the labels text property to display the total.
</pre>
If you have a strongly typed DataTable, you may have access to the Properies of each DataRow to use instead of getting the column data using the index of in the row. For example R.Price instead of R(1).
Hope that does the trick.

Catch ex As COMException
How can i clear my Exception ? ex.Clear ?

You don't have to clear the exception, you have caught it.
Exceptions doesn't work the same way as the Err object did. When there is an error an exception object is created, and the error state is contained within that object. There is no ever-present global object that you have to clear.

Hi Everyone,
Appreciate if anyone can post the code equivalent of
iFileNum = FreeFile()
open FileFullPath For Input As #iFileNum
sFileContents = Input(LOF(iFileNum), #iFileNum)
Close(#iFileNum)
in VB.NET 
Thanks,
K

I have no idea what most of this does ( what does FreeFile return ? What does it do ? ), but the System.IO namespace has File, Directory and Path classes with static methods to perform all sorts of file operations. VB2005 also has My.FileSystem as shortcuts to all sorts of stuff.

Do a file.open and then say ReadToEnd, then do a file.close.

You cannot turn 3 dlls into an exe. If you're using Vb.NET, you can certainly import the dlls very easily and use them in yuor code, but you will still have dlls you need to ship with your exe.

Hello everyone, I am very new to VB.net (and programming for that matter) and I am trying to get a handle on it. I am trying to understand datasets, data grid, data adapter, data connection and how they all work together. I have found a few tutorials that helped a little but most have been for VB.net to an SQL database and I am trying to use this with an Access 2003 database not SQL. Does anyone know of any good tutorials that explains this with an Access DB? I am sure I will have tons more questions. I appreciate any help that you can offer to me.
I can give more specific information about what I am trying to do but at this point I think would be best if I learned more about the process rather than waste your time trying to teach me.

You can use most of the tutorials for the SQL Server database with very small changes.
What differs is the connections string, and the name of the classes that you use. For an example you use OleDbConnection instead of SqlConnection and OleDbCommand instead of SqlCommand, but they work almost exactly the same. You have to get to much more advanced stuff before ever seeing any difference at all, apart from the connection string and the naming of the classes.
You can get examples of connectionstring on connectionstrings.com[^].

Private Sub text1_KeyUp(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles text1.KeyUp
If e.KeyCode = 13 And btnstat = 1 Then
MsgBox(e.KeyCode)
End If
End Sub

Do you mean somthing like sending a tab, instead of a carriage return?
Private Sub TextBox1_KeyUp(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles TextBox1.KeyUp
If e.KeyCode = Keys.Return And btnstat = 1 Then
SendKeys.Send("{TAB}")
End If
End Sub

I have to program a scenario like this.
I have the cluster server and the user running the service.
I need to query if the user is a member of a group xxxx on the nodes.
On the node say NODE1,
Group - xxxx has the below members
--TEST1\Domain Admins -- (again a group named 'Domain Admins'
in TEST1 domain)
--TEST1\Admin -- (user called Admin in TEST1 domain)
>From cluster machine, I connect to "NODE1" using wmi. The below two
queries succeed.
a.SELECT * FROM Win32_GroupUser WHERE GroupComponent =
"Win32_Group.Domain='NODE1',Name='Domain Admins'"
b.SELECT * FROM Win32_UserAccount WHERE Domain='NODE1' and
Name='Administrator'
But the below two queries fail. These are similar to a and b but with
different domain "TEST1".
My program fail even though Group xxxx has TEST1\Domain Admins.
c.SELECT * FROM Win32_GroupUser WHERE GroupComponent =
"Win32_Group.Domain='TEST1',Name='Domain Admins'"
d.SELECT * FROM Win32_UserAccount WHERE Domain='TEST1' and
Name='Administrator'
Even wbemtest.exe succeed for a and b queries but fail for c and d from
the cluster server.
But when I run wbemtest.exe on the "NODE1" directly then all the
queries succeed.
How do I make wmi queries succeed for different domains from the remote
computer?
I need to write a VB.Net program for this. I will be adding this code
to existing VB.Net application.
