I've heard many people who said that it is impossible to change a MAC Address, however after googling there are ways to change Mac address in Windows XP. Therefore, is it possible to change MAC Address using Visual Basic .NET? For both XP and Windows 7?Test

Im not onabout the external Ip address. I know that cannot be changed(I have a static one from my isp.) Im onabout changing the internal ipaddress... for example changing from: 192.168.1.150 to 10.0.0.125 -
I'm making a network control center. so is there a way i can change my IP address with a text box and a button. so the user would type there desired IP address and click a button and it would change the IP address of the computer.I know how to change my IP address the long way using network places, so this is one of the reasons why i'm making this program.

View 1 RepliesOkay this app basically only partly works. I have a Checklistbox that I am using to import a list of ip address from a txt file which is coded to a button.
Button #1: This part of the app works great. I can successfully open and import a list of ips from a txt file.
Button #2: This is where I am having all my trouble. I wanted to code up a button that would use the checked item (ip address) from the list and change my current ip address to the one listed. My first thoughts were it was something to do with the checklistbox so I just said screw it and decided to code the second button to change the ip address to a preset address and even that doesn't work.why this code isn't changing my ip address to the one listed 192.168.1.1.

what is wrong in my code to change my ip to the one listed in there? Would be even better if someone could show my how to set the value of the ip to variable "ProxyList".
So I have a TreeView that starts off empty. Sequence of events is as follows:
Add a new root node. Code makes the label edit box pop up immediately, and I give it a name.
Add a new subnode to that root node.
Add a new root node, after the first one. The label edit box pops up, and I give it a name.
The second root node takes on its new name, but so does the subnode added in step #2. Now, it's not really the subnode's text; if I examine that TreeNode in the debugger, it has the proper text for a subnode. But that text that was entered into the root node sticks around through expanding and collapsing its parent node, until something else happens and I need to rebuild the tree.
I'm building the tree in kind of an odd way - removing all root nodes from the parent, all child nodes from the root, updating all the tags and text, creating new nodes, then re-adding the nodes to their parents - but I've checked, and the proper text is being associated with the proper node. The TreeNode that is showing the wrong text has only ever modeled the one object, never had anything else in its Text property, and has its text set back to the right value ("untitled action") right before being re-added to its parent node.
All I can think of for a culprit is the code for the label editing box, which is based on an MSDN sample:
Private Sub EditSelectedCategoryName()
If Not ActionList.SelectedNode.IsEditing Then
ActionList.LabelEdit = True
ActionList.SelectedNode.BeginEdit()
[Code] .....
EditSelectedCategoryName is called by a context menu item's Click event, right after the new root node is added and made the selected node. The DisplayName setter in the AfterLabelEdit event handler is what triggers another chain of events that rebuilds the tree. So am I screwing up some internal structure of the TreeView by altering its contents in the AfterLabelEdit event?
I'm running into this problem when it comes to determining a network logged on username and i hope someone can help me out or atleast point me in the right direction.Situation:1 Windows 2003 server that is serving files through Active directory. No Dfs installed, just plain files sharing.1 or multiple clients that access the files, make modifications and creates or deletes files. For arguments sake let's say that the clients are Windows XP computer and the users are logged on to the local domain (AD).Currently available:When the client alters, creates or deletes a file i have a (VB.Net Windows Service) script that tells me that this is being done and stores a record in a database for this action being performed.Desire:I wan't to know the client's ip-address, computername or logged on username so that i can store this to. I have tried about 20 different scripts but all check the username on the server side and not the client. So now i either get back "SYSTEM" or "NTAUTHORITYSYSTEM" instead of the user's AD name.Below is the code i use to monitor the directory and or file changes.The "writeDBLog" is where i want to pass the username to write to the database.

A routinely used application suddenly became impossible to access, with and error code indicating that the "VB Backup\Backup" file cannot be found. When I click File Open, the projects display as always. I select the application, double click the .sln file--and nothing happens. When I try to access the .vb file in Solution Explorer, it says "Cannot find VB Backup\Backup Files."
What are the Backup Files, when are they created, and why would they suddenly be "gone?" Is there any way to rebuild the Backup Files? I used the application last night and it worked fine. Today it can't be opened because the Backup Files cannot be found.
I have backups of the application folders, but get the same error message. Cannot be opened because the Backup FIles cannot be found.
