1. when a parent node is checked, all of its child nodes is checked.
2. when a parent node is unchecked, all of its child nodes is unchecked.
3. checks and unchecks all the parent nodes and child nodes with the help of buttons.
all these things are using some sort of recursive function and thats cause the problem. i use all that in aftercheck event of treeview
So you were able to do those 3 things?

1. when all child and parent nodes are unchecked, then , when child node is checked then i need to also check its parent node. thats exactly what i want to do.
to do this you will need to 'override' the aftercheck event of the treeview otherwise it's going to cause problems as you already noticed.
the easyst way to do this is with a boolean. when the aftercheck event is fired check if its a child node or not if so put boolean to false and check the parent after this you put the boolean back to true.
and then as first check in the aftercheck event you check this boolean if its false you do nothing else you do the code needed.
this is probably not the best way to do this but it should work and that's how I would start and see where it gets me.
if you have problems with implementing this post the code (or part of the code) in the aftercheck event that way I can have a better picture of what you are doing and what is going on.
hope this helps
If my help was helpfull let me know, if not let me know why.

Handle the TextChanged event and convert the text as you go using ToUpper on the string class.

It has been a while since I've done this, but as I recall you need to capture the selection (even although it will be zero length) before making the change then replace the selection afterwards.

Hi, you can manipulate the KeyChar property inside a TextBox.KeyPress handler;
this is an example in C#:
private void tb_KeyPress(object sender, KeyPressEventArgs e) {
e.KeyChar=e.KeyChar.ToString().ToUpper()[0];
}

Nope. Trap the KeyPress event and change the KeyCode from lower case to upper case.

hi ,
I am creating a controls of type combobox at runtime when user clicks a button . If i click the combobox ,it show the custom properties of combobox inherited from Combobox.
Here when i am entering items of a combobox and clicking again that particular combobox , It's not showing the items which i entered .
So how to maintain those items of that combobox when users comebacks to that particular combobox 1,,,etc
1) How to Handle Items Property as a property for runtime combobox ? <br />
<br />
2) How to Show the items of particular combobox when user selects again?

You could code against the Validate Event to add the Text to the Combo Box:
If Me.cbo.Text <> "" Then
Me.cbo.Items.Add(Me.cbo.Text)
End If

This is not the thing . It deals with String Collection Editor and some other things .Those items are not persistent there for that combobox .
I want to add only Items as strings .I amnot gettingthe correct help from web .
I am new to this thing .

You won't get the local ip of the machine, only the ip from the router that it is on.

It only knows whats up to your router, in terms of ip, then the router redirects.

Does VB.Net allow you to mouse over an image and enlarge it? Or am I completely off? Is dreamweaver the answer...I am new as of yesterday to all of this so Im learning everyday!
I am excited to learn this!!
thanks

You can probably use the MouseOver event to do whatever you want (for the most part) with the image when running the mouse over it.
