Making your own controls is not something that can be explained in a forum post. This subject can take up entire books and still not tell you everything about control creation.
As you've probably figured out by now, this will take a lot of research. Start Googling for "vb.net create custom control" and you'll come up with a large list of articles covering a wide range of control creation.

My best source is Google. I taught myself everything I know about custom controls by trial and error and Google. There is no one site that has everything you need to know, not even the basics, on how to create your own custom control.

What do I need to do to correct the problem.
Thanks for any help!

Is there a way to override the code that vb.net generates for Deletes, Updates and Inserts?
The code generated is slowing down my app for these functions, especially for only 1 record.
I'm using the BindingNavigator controls to add, update, delete, etc.
PPOBindingSource.EndEdit()
PPOTableAdapter.Update(Me.DwCustomDataSetPPO.BenefitAdj_PPO)
Is there someway to over ride what Vb generated and create my own code for these functions?
The generated code is inefficient and convoluted.
Any help greatly appreciated.

I am trying to create a setup project that will upgrade certain .dlls that are only used by my project. The idea behind this is that only the required dlls need replacing as opposed to the whole application being re-installed.
The setup project I have created at present will not overwrite the dll but will install the updated one if I previously remove the old one manually.
I am not sure if this is the way to do it and would appreciate any help/advice on this matter

Hello,
I have a MDI-application in VB.NET. Now I want to show a dialogbox in it, but while the dialogbox is showing, it should not be possible to click on the other forms (eg. close parent-form of my MDI-application).
Can anyone tell me how to do this?
Thanks!

------------Begin Update on my original question
I have been able to successfully store the attribute list in the TreeNode.Tag field in the AddNode function.
I have changed the line of code in AddNode function
inTreeNode.Text = inTreeNode.Text & " " & (attrNode.OuterXml).Trim
TO
inTreeNode.Tag = inTreeNode.Tag & " " & (attrNode.OuterXml).Trim
I do not see the Tag field displayed on the treeview though.
Then I changed the line of code in SaveScreenChangesToFile function
Else
StreamWriterForXml.Write("<" & currentTreeNode.Text & ">")
TO
Else
StreamWriterForXml.Write("<" & currentTreeNode.Text & " " & currentTreeNode.Tag & ">")
-- now I can save the attributes to an output.
But part of my original questions remains... how to display attributes in treeview? Do I HAVE TO populate the TreeNode.text field with attributes to see it? Which will have the effect of complicating my function when I go to write it out as a file. I will have to parse the TreeNode.text field more carefully.
-----------End Update on my original question
Hello,
I am having success with the following code in parsing element's attributes and displaying them in a treeview in visual studio 2003 in a vb.net application. However, when I go to save the treeview using the following code, I do not get any attributes. I am wondering if the way I am storing the attributes in the treeview is the problem. It seems you can display attributes in a treeview but they are still considered elements in a treeview structure. Below is the code I am using. By the way, when I only display elements in the treeview using the code below, there is no problem displaying or saving elements. It is only when I try to add the ability to display and save attributes that my trouble begins because I miss creating ending tags in the saved output and it just gets totally wierd for other things. I am sorry I am not explaining all the output problems when I try to deal with attributes. If anyone is able to shed some light, I will be glad to bore you with the details.
thanks.

Looks like your Page_Load() event is being fired every time. Check your other code to see what's happening.

So... what is the error message you get - or describe the unwanted behaviour of the program so we have at least some ide where to start to help you. An example of the code you are using would also help (but don't paste the entire program ).
