When i write this code:
Dim pubsadapter As sqldataadapter = New sqldataadapter("select*from authors", pubssqlconn)
then build it
the result: sqldataadapter is not defined
Go forward and never Stop....

Did you put this at the top of your code file? You have to declare the namespaces you want to import so these classes are defined.

Imports System.Data.SqlClient

Anybody here tried snmp in vb.net? Could use some help on how to get started. Any ideas?

You didn't say what you wanted to do with SNMP, so the documentation starts here[^]. You'll, again, have to P/Invoke everything since there is no native support for these functions in the .NET BCL.

Basically, I wanted to perform the mac-to-ip conversion there. If I could retrieve the computer's IP address, then query for the NIC's MAC address, I am there. Is that right?
|
|
|
|
|
Nope. If there is no SNMP service running on the target computer, you won't get back anything. The NIC's driver must support such a function and I haven't seen one yet that'll do what your describing. Just the normal ARP stuff is supported...

I've come across an application that enumerates the mac addresses of computer connected to a certain switch and it required me to enter the snmp community string. Any idea how to implement this kind of feature?
|
|
|
|
|
That's because the switch has SNMP support built into it. The app just asked the switch and it reported everything through its normal administration interface, SNMP.

Download the Primary InterOp Assemblies from Microsoft. There are examples there on how to instantiate any office application and then programatically invoke its methods and functions. Opening a Access file should then be a snap.

Thank u very much. I'll try
Good luck

In my app my main form has 2 panels seperated by a splitter control - on the control on the right the user can add windows forms (don't ask) and then move them about using the title bar or resize them as you would a normal resizable window - the problem is if the user resizes the panel using the splitter the app kind of loses track where the windows are on the panel.
Is there a way to tell the app where the windows are once the resize has been done?

What do you mean by "loses track of where the windows are?"
What happens to the windows?

Sorry, I realise I didn't explain that very well. Essentially the user can move the windows forms around on the panel and can resize them as per any resizable windows form but after the panel has been resized using the splitter it seems that windows thinks the window isn't where it is currently displayed but where it was before the panel was resized. Does that make sense?

You might want to try Invalidating the Panel control to get it to repaint itself, along with all its child controls.
Panel1.Invalidate()

Thanks - that works a treat, why didn't I think of that?  It's been that long since I did an GUI work I seem to be starting over.

Can anybody tell me if there is a way to use a list in a Rich Text Box to create a file structure?
Here is what I’m trying to do:
I have directory names listed in a Rich Text Box. An indented line means that-that particular name will be a sub-directory of the line (directory name) above it.
I would like to write a function that will build the directory structure on a disk.

It's up to your coding ability. Anything is possible.
In this case, you'd have to keep track of the parent directories depending on where your at, count the number of tabs to denote which level the next directory is going to be at and what it's parent directory is going to be. Then, it's a simple of matter of creating the directory.
It's not the most accurate way to recreate a directory tree though. You have to make sure that the data your getting fits the file format specifications your using. ANY deviation will result in an incorrect tree being built.

I'm not writing the code for you. You have to at least make an attempt at it. You won't learn anything if someone else writes the code for you. It's not as simple as you might think.
You'll have to think about each step in the process. Starting with 'Read the first line of the RTB.' What are you going to do when you read the first line of the RTB? Set this as the current directory? What am I going to do if this path doesn't exist? Create that path? How am I going to keep track of the current parent directory? What am I going to do when one line of the RTB has 3 tabs in the beginning of the line and the next one only has 1 tab? How do you keep track of the tab depth and set the CurrentDirectory accordingly?
Creating the directories is easy with Directory.SetCurrentDirectory and Directory.CreateDirectory.

Awww c’mon now. I'm sure you don’t mind writing hours and hours worth of code for somebody who you don’t even know.
Seriously, I’m going to give it a shot. I appreciate what you have told me so far. It gives me a good place to start.

Why not use a tree view? It's much easier.

Here is some blatant self-promotion, but anyway here goes:
I have some code that does something similar in a recent article I wrote for code project, it is not creating directories but populating a tree view (which is a similar heirarchical structure to directories). Take a look at the Word and Category classes to get an idea of how you may implement your solution - it works on a plain text file rather than RTF, and in place of indents I've used $ symbols.
