Well, it depends on how your network is setup. Unless you're using Active Directory or the old NT Domains, there is no central database that lists all the machines on the network. You'll have to ping each and every IP address in your net to see if there is a response. But, that does NOT mean it's a Windows machine. It can be something else, like a network Printer, some server, Linux box, ... Even a non-response doesn't mean that a machine is not there. It could just be turned off.
Even using Active Directory or NT Domain, there's no guarantee that every machine on the network is a member of the domain.

Hi there,
I'm trying to build a simple application at work and im having a few problems. I'm not a programmer and am learning as i go though.
My problem is regarding the OpenFileDialog in the application. When clicking "open", the file dialog box will open for me. But when i click tyhe file and then open, nothing happens. I am probably going about this the wrong way.
All i need is a function so that the user can open the file they click. I do not want the file to be opened in my application but in the file type application (.vsd and .pdf).
I would greatly appreciate any help on this matter as the project is due pretty soon.
Thanks for taking the time to read this
Regards
Peter

I am not sure about vs2003 but in vs2005 it is System.Diagnostics.process.start(filename) and this will start the file in it's application.
Hope it helps.

Hi, I'm using VB.net 2003. I'm making a tcp/ip server/client program using "UNOLibs Class". I would like to know what is the best way to create/get a unique program ID so the server can identify witch client it's talking to. I would like an ID in case the two clients are from the same IP.
I can use a random number generator at startup, but would it be the best way?
Thanks,
Rob

Thank you very much!!
That's exactly what I was looking for. I had it working with a random number generator, but I think this will work better. Thanks again.
The fun part of programming is going to bed every night a more intelligent person.

please help on how to kill network connection..
|
|
|
|
|
That depends on what you mean by "network connection". Is this a connection in your own app, or some other app? Are you trying to block traffic? Need more details...

it is the other application that try to make connection..
|
|
|
|
|
Then no, you can't close it's connection directly. You have no access to the other app's connections.
The option you have is to either install your own proxy server, so your app connects to it and the proxy connects to your apps server, or write your own proxy server. In either case, you can break the connection, and even filter traffic, because you now have a "man-in-the-middle" that now controls one end of the connection.

Hello,
I want to compare an image to each image in an ImageList.
I tried this:
For Each Img As Image In ImageList1.Images
If Img Is [ComparePicture] Then
...
Next
What am i doing wrong?
I also tried: If ImageList1.Images.Contains([ComparePicture]) Then
...
End If
But then i get the message: "Specified method is not supported"?
Help pls?

You can't compare Image objects like that. If you want to compare the actual pixels, you'll have to write some code that will take both Image objects as arguments and do the comparison yourself. You'll probably want to first make sure that the images are the same dimensions, then the same color depth and pixel format, see if they have the same options (like a transparency), then go through each pixel, one-by-one, and compare them. If every pixel is the same, and all the other tests pass, then the images are equal.

Hello,
VS 2005
I have 2 datagrids.
The 1st datagrid will contain parts that the user will select and then click a button that saids add part. This part will be added to the 2nd datagrid. Which is the best method to add these rows to the datagrid. The fields will remain the same in both datagrids. So no need to change them.
Once the required parts have been entered into the 2nd datagrid they will be saved to the database. What is the best method so save the data in the 2nd datagrid, as the user can save periodically.
Many thanks in advance,
Steve

hi there,
I am new to VB2005 Express, and would like to know if it is possible to change the location of a picturebox via code at runtime.
In my program i have the screen cut into quarters and would like to display an image from one of the quarters to full size. The top left works like a charm. The others only fill half the screen from where they are.
Thank you.
