Getting ALL Computers On Network?
Jan 22, 2012Part of an application that I'm building searches the network that the current computer is connected to and returns a list of the IP & MAC addresses and the hostname. It is based largely on the post by richard__deeming at [URL] At the moment, it will only get the information about computers that are in the same workgroup, but I have several computers that need to be shown, that are joined to a domain rather than the workgroup. How can I get the program to find every computer on the network?

View 3 RepliesCommunications :: Write A Program To Ping Computers On Network To See If They Are Turned On?
Jul 4, 2008I am trying to write a program to ping computers on my network to see if they are turned on. So far i have the following:
Code:
If My.Computer.Network.Ping("192.68.0.5") Then
MsgBox("Computer is on.")
Else
MsgBox("Ping request timed out.")
End If
If i use ip addresses, this works fine but i would rather use hostnames due to the ip addresses being dynamic (something which is outside my control). Using the hostname, it reurns "Computer is on" if the ping is successful, but if the hostname cannot be found, instead on returning "Ping request timed out", an error occurs as follows:
A first chance exception of type 'System.Net.NetworkInformation.PingException' occurred in System.dll
Finished A Console Application And Deployed It To Several Computers On Our Network For Testing
Dec 17, 2011I have recently finished a console application and deployed it to several computers on our network for testing. As it is just an EXE a copied to the hard drives of selected computers for now. When the app is launched it writes info to an sql DB so I always know which computers it is on.
During the past few weeks I have modified this app at least 6 times (improvements, adjustments, etc)
It is a paint to keep going back to the computers to update it with the new version, and getting mixed up which version i am on - LOL I am looking for advice on how I would go about doing this automatically, for example, it would be cool if I just had to put an updated file in a repositry and clients would use this to update.
In Visual Studio, when I view the properties of my application>assembly information - I can set a file version. Is it possible to extract this info and store it in a variable? I would like to dump the in my DB. Also I could then possibly compare the file version of the launched app against an updated file in a network share folder.

Feb 15, 2012I have been messing around with the scanning packages(WIA and TWAIN) and have gotten WIA to work, but not as intended. At first I used the common dialog to show a Image Aquisition Wizard, but that did not return desired results. Next was twain, but st managed to find was the same C# program over and over and over again, "TwainGUI". A program written by NETMaster on codeproject.What I would like to do is scan from the ADF and save immediately to the users working directory. The problem is I can't get WIA to keep scanning until the ADF is empty.

Jan 28, 2011So - we are FED UP with our medical records packaging (document imaging) system and want to create a simple filing interface for our scanners to use in VB. Part of this deal is getting VB to interact with a TWAIN Driver.
There is some code out there for ASP.NET and C# - does anyone know of a VB.Net based code I could look at?
I have spent part of my day trying to recreate the ASP into VB but the calls are just different enough to get interesting.

View 12 RepliesScanning With TWAIN - Hide The UI
Feb 18, 2010I am making an application to scan with TWAIN. I can get to state 4 OK, and scan with the UI. But I need to hide the UI. When I do this the scanner does nothing. I believe it needs some capabilities set (like height and width). So I try to get the physical height and width so I can set them. Herein lies the problem. I get 18874402 back for the physical height and width. (neither can I get the units). I get RC=SUCCESS. I don't think it could be a signed/unsigned issue because what boundary is at 18 million +/- with whatever units? I tried some other code I found but that returns 0. I can't figure out what I am doing wrong. Here's the code:
