'Good' is a matter of preference and past experience.
You might want to check out "Professional VB .NET, Second Edition", or "Advanced .NET Remoting in VB .NET". You can find both at Amazon[^].

Set Current Directory

Hi All.

Based on a suggestion that Dave made earlier, I’m trying to ‘set my current directory’ to the value of a variable.

homeDir is a string that holds the current path i.e. c:\current\path

I can’t figure out how to use Directory.SetCurrentDirectoy with this variable. Can anybody help?

Thanks
Brad

You might want to try posting the code that you're using too. It help to diagnose other potential problems with what your doing. Anyway, at the top of your code, make sure that you have:

Imports System.IO

Then, it's just a simple matter of:

.
.
Directory.SetCurrentDirectory(homeDir)
.
.

That did the trick!

I forgot to add: Imports System.IO

Thank you very much Smile | :)

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
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?

Dave Kreskowiak8-Jun-04 15:14

8-Jun-04 15:14

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?

8-Jun-04 23:58

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.

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()
