Friends,
I think it would be better if I clear the supposed use of such a control.Here it is..
S.No. Account Name Credit Debit particulars
- - - - -
S.No. would come automatically and rest of the things would be supplied by the user.On hitting the enter key user will go to the next row(or we can say next S.No.).I want this in VB as I am using VB6.0 and Ms-Access.
Thanks.
Your Friend in need

Thanks in advance.

Hi folks,
I have my application ready, can i know how to make a setup for the application, like Package and Deployment in VB6, how to do that in VB.Net.

Use the menu: File-->New-->Project...
Select "Setup and Deployment Projects" from the list on the left.
Choose "Setup Project" or "Setup Wizard" (the wizard might be easier if you've not done this before)
Give the project a name and Bob's your uncle.
If you use the wizard it will guide you on the more basic steps.

Surly,I'm using VB.NET to do this job.
Most of infomation I'd like to
find was in COMAdminCatalogCollection.
But I couldn't find a way of retrieving imfomation of state of Object activated. I'd like to know how many Object is Activated as if I see the COM+ Management Tool provided in Windows 2003.

set RecordSource to the table or query you need
then set datagrids data source property to adodc1

Does vb have one, and if so what is the syntax for a #Define equivalant?
do you need to investigate an online backup company
|
|
|
|
|
Sort of. VB6 has #Const, which allows you do define a constant variant, which can then be used in a #if..then..#else construct.
But it isn't as powerful as the equivalent features in C

Hi guys,
This is my first post here and need a pretty big favor from someone. I need to write a script that will allow me to imput a path (and be able to browse to a path) on my network, imput how many boxes (folders named Box001, Box002, etc.) I want to create and how many CDs(folders named CD001, CD002,etc.) that I want to create.
I just a Visual Basic program called RealBasic to design the visual layout, but can't figure out how to make it all come together. I could give someone a print screen to show the layout of how it needs to look just e-mail me at e-mail
I know this is probably no enough information to go on but if someone that knows VB pretty well could shoot me an e-mail I could explain a little better.
Thanks a lot!

I am looking for VB code that deals with Wireless devices. I have a wireless network at home and I am curious to know how programs like Net Stumbler can pick up different wireless signals. If anyone can help - much appreciated.

Hi,
It takes some lower level interaction with the cards devices drivers. Here are a couple of links to look at:

I am doing some "creative" syntax hilighting with VB.NET and RichEdit. Only problem is it shows the selection box! "NoHiglight" isn't going to work in this case because the text actually has to be selected to change the color. (I tried it anyway, didnt work)
Anyone got any ideas?

you'll have to use the LockWindowUpdate function from the User32.lib
The LockWindowUpdate function disables or enables drawing in the specified window. Only one window can be locked at a time.
Declare Function LockWindowUpdate Lib "user32" Alias "LockWindowUpdate" (ByVal hwndLock As Long) As Long
Applicable to VB4-32,5,6
Parameter Information
hWndLock
Specifies the window in which drawing will be disabled. If this parameter is NULL, drawing in the locked window is enabled.
Return Values
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero, indicating that an error occurred or another window was already locked.
Declare the function - usually in a .bas module
Declare Function LockWindowUpdate Lib "user32" Alias "LockWindowUpdate" (ByVal hwndLock As Long) As Long
Where your code is...
Private sub WhereEver()
LockWindowUpdate Rich1.hwnd
your code goes here...
LockWindowUpdate False
end sub
Hope this is useful

I'm new to vb.net and I was wondering if it would be possible to use regex on a treeview?
I haven't got any code but at least that makes for a quick read..
what I would like is to be able to traverse a treeview for a regex, then building a new treeview with the nodes found maintaining the original structure of the tree (parent - child)
inputs are extremely welcome
peace

In a nutshell ...
Private Sub btnMatch_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnMatch.Click
targetTree.Nodes.Clear()
Dim Expression As New Regex(txtExpression.Text)
Dim Matches As MatchCollection
For Each node As TreeNode In sourceTree.Nodes
If Expression.IsMatch(node.FullPath) Then
targetTree.Nodes.Add(node.Clone)
End If
CheckNodes(Expression, node, targetTree)
Next
End Sub
Private Sub CheckNodes(ByVal expression As Regex, ByVal node As TreeNode, ByVal target As TreeView)
For Each child As TreeNode In node.Nodes
If expression.IsMatch(child.FullPath) Then
NodeParent(target, node).Nodes.Add(child.Clone)
End If
CheckNodes(expression, child, target)
Next
End Sub
Private Function NodeParent(ByVal target As TreeView, ByVal node As TreeNode) As TreeNode
If node.Parent Is Nothing Then
For Each Parent As TreeNode In target.Nodes
If Parent.Text = node.Text Then Return Parent
Next
Return target.Nodes.Add(node.Text)
End If
Return NodeParent(target, node.Parent).Nodes.Add(node.Text)
End Function

Maybe this isn't the best way to handle it, but how about using .Split() on the string, supplying the newline character?
Dim lines() as String = _
myBigString.Split(System.Environment.NewLine)
Dim i as integer
For i = 0 to lines.Length - 1
'--do something with the line
DoSomething(lines(i))
Next

Hi,
Yes it should works, but the problem is that I will make a copy of my big string, and it will use more memory. I am thinking about use your method, but them clear my big string...

How about using a StringReader then?
Dim sr as System.IO.StringReader = _
new System.IO.StringReader(myBigString)
Dim line as String
'--read the first line from the string
line = sr.ReadLine()
Do While Not (line Is Nothing)
'--do something with the line
DoSomething(line)
'--read the next line from the string
line = sr.ReadLine()
Loop
