I need to write a program that can be distributed over a network of 400 computers and that can be updated if necessary. How do i do that with VB if i can at all? What should i learn?
View 2 RepliesI 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

View 1 RepliesPart 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 RepliesI 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.

'tree' of all networks and systems available would be a major plus.

View 2 RepliesI'm trying to make my program compatible with more computers, even if their computer is not up to date. Im trying to make it compatible with the following windows versions, all versions so if it has home, professional, server, etc...
Windows 98
Windows 2000
Windows ME
Windows XP
Windows Vista
Windows 7 RC
Now, my program is compatible with the bottom 3, and with 64 bit computers, the problem is that my program has to have the .NET framework 3.5 installed, which meens XP needs updated and that framework installed, and on earlier versions, it wont install the framework through windows update and the like, also, I cant expect people who want to use it to have it installed, can anyone explain a way for me to make it so my program if its possible, then whatever features may use that framework, if just not calling that code will stop the program from crashing, or if i can make it use older version instead of a newer version framework, maybe only in certain cases.

View 6 RepliesI've just created a program in Visual Basic.NET 2010 Express Edition, and the program works great on my computer. Unfortunately, when I try running it on other computers, the process on the Task Manager for it comes up for literally 2 seconds and then goes away, and the program does not run. Basically, the program doesn't open. I'm not sure why this is happening, and I'm not getting any errors.
I am running Windows 7 Ultimate 64-Bit, and I've tried getting it to work on two other computers, with no luck. The first one had Windows 7 Home Premium 64-Bit, and the second one had the same operating system as my computer. All computers have the .NET Framework 4 Client Profile installed, which is what my application is compiled to work with. I also tried compiling it to use .NET Framework 4 (without the Client Profile), and that didn't help.
If it helps, my References are as follows (which I believe are the defaults):
- Microsoft.VisualBasic.PowerPacks.Vs
- System
- System.Core

From all the chat applications I successfully made each and every one of them required me to port forward my router so that the data can be received. Now my question is how can I make my chat program work on computers that have routers with most of the ports blocked, how do traditional chat programs do it? Perhaps The chat program intercepts packets then sends it to a known port such as 80?
