This is not the right forum where you share some link for discussion. This is a forum where people ask technical questions related to .NET Framework, if they get stuck.

I would suggest you to post in GIT[^] or Lounge[^] to move ahead. Since you are new here, I would suggest you to post in GIT and get a little conditioned for CP.

Overall, which database? What are you trying to do?

About database caching, read here: http://en.wikipedia.org/wiki/Database_caching[^]

           RS("batchno").Value = Me.DGVRecord.Rows(i).Cells("batchno").Value
           RS("expirydate").Value = Me.DGVRecord.Rows(i).Cells("Expiry").Value

This is because you have written code as such.
Here:

For i As Integer = 0 To DGVRecord.RowCount - 1
           RS("productname").Value = Me.DGVRecord.Rows(i).Cells("Product").Value
           RS("batchno").Value = Me.DGVRecord.Rows(i).Cells("batchno").Value
           RS("expirydate").Value = Me.DGVRecord.Rows(i).Cells("Expiry").Value
       Next
RS.Update()

You go in a for loop to define RS but update is outside for which makes only the last for loop executed/set value to go for an update.

Use Visual Studio DEBUGGER to see how things are happening, what is the execution workflow and you will be able to understand and resolve it.

You don't save and load TreeView items, you save and load the objects used to create them. Take a look at some of these links[^] for some examples.

You cannot hurry people who don't work for you. It's a Sunday, only had a single cup of coffee, and I don't have a stake in the outcome. If you're short on time, then you'll need to learn to manage your time more efficiently.

You won't receive code either; I'll be happy to answer questions and help with specific examples, but we're not a charity that's in the business of providing free code.

Now that's out of the way, on to your question. You save/load a tree one node at a time, question is where you'd save them. Let's assume a database, like Sql Server. You'd have a table in there, with a field that points to it's primary key.

SQL

CREATE TABLE SomeHierarchy(
  MyKey     BIGINT,
  MyParent  BIGINT
);

Any root-items would not have a reference to a parent.

..I suggest you search for some examples, there's probably a few on CodeProject Smile | :)

VS Editor Extensions, Split Code View?

Don Rolando20-Jun-12 7:06

20-Jun-12 7:06

I have seen samples for custom code editors (modified syntax highlighting, intellisense, etc.) and I have seen samples for custom visual editors (as UI for editing files when opening with visual studio).

But: How can someone build Visual Studio extensions which allow both; a split code/design as the built-in XAML editor offers?

Is that possible without creating my proprietary editor control from scratch as part of my view?

Any hints appreciated Smile | :)

PS: My goal would be some custom XML with an visual representation on top. Comparable to the XAML editor, but not for UI stuff.

What do you mean you didn't find it? All you had to do was click the link I gave you.

Hey!

I've created a new on screen keyboard to use as a replacement for the default windows keyboard "TabTip.exe".

How do I make it so my new app gets called whenever someone clicks the little keyboard icon that pops up beside a text field instead of "Tabtip.exe"?

Thanks!

If they did then I would expect they would have responded to you. However, I cannot see what your question has to do with the .NET Framework; maybe you need to reword it.
