Specific Ip Address Selection?
Feb 22, 2011
im in the process of using vb.net code to return the ip address of my machine its working sorta correctly i can get the right ip address if i change the addresslist.getvalue(0) from [0] to any where up to [5]this im guessing is an array of information in the network adapter or something im not real interested in the other information in the other values my problem is depending on weather i have ipv6 options enabled in my adapter settings the true(192.xxx.x.x) is in value(2) for on and value(3) for off also i tried it on another machine and it came back as value(5) of 12 my problem is i can display every value() that has information in it in a text box but i cant make the program find the right address to use(192.xxx.x.x) this code runs and produces a multiline textbox with up to 11 lines of data in it and the ip address is visible in the list of data
Dim myIPs As System.Net.IPHostEntry = Nothing
Dim ip As String
Dim h As System.Net.IPHostEntry = Nothing
[code]....
but is there a way to either compare the adapter address list to a mask to get the correct value() for the ip address or is there another way to return the ip im not aware of?

I've searched and seen alot of posts about obtaining the mac address of computers but I'm not sure if I understand completely or if those are the ones I need.
I am needing to obtain the mac address of a specific computer via an ip address. Most of what I've seen returns to me an array or list of items.

I'm using a list box with multiple selections to add to my string -- I can't figure why my conditional doesn't seem to work. Every selection in the list box is intended to add specific literal to the string I'm building. What am I doing wrong See my code:
'special conditions
strScopeParagraph &= "Some special conditions which will require specific attention are:"
'strScopeParagraph &= ControlChars.Cr

So I have a datagridview being populated with data from a database.At this point a user may or may not selected (via mouse click / key press) one or more rows within the datagridview.I need to (upon selection) create a new dataset, datatable and add rows with the some data from the said datagridview.
For example, if a table had nothing but names, e.g.
Joe
Sean
Larry
Chris
Upon the user clicking, dragging a selection over Sean and Larry to add those names to a new dataset so I can pass it to another method for further processing.
[Code]...
Input array is longer than the number of columns in this table.It looks like I'm either missing a column declaration or adding the table to the set?

What I would like to do is be able to programatically direct the application to use a specific IP address from the one the server (A) has.

Working on a project that contains a listView (populated from a database already) and several textboxes. What I am trying to do, and cannot figure out, is to program this so that when a user makes a selection in the listview, it hits a specific database, and based on certain values within that databse, the textboxes are populated with things such as name and address, etc..

I'm trying to use the DHCP API (using the references on pinvoke.net) to retrieve a computer's MAC address when given the IP address but I can't get the code to work. I've run all the C# code on pinvoke.net through the C#-to-VB converter but I'm stuck now.
Here's what I have so far. The value of res is always 5 (should be 0). Thing is, I can't find any documentation on what the return codes mean
vb
Private Sub GetMACDim client As String = "1.1.1.1" Dim server As String = "0.0.0.0" Dim si As New NativeMethods.DHCP_SEARCH_INFO si.SearchType = NativeMethods.DHCP_SEARCH_INFO_TYPE.DhcpClientIpAddress si.ClientIpAddress = Convert.ToUInt32(StringIPAddressToUint32(client)) Dim res As UInteger Dim oInfo As IntPtr

I wonder if it is possible to find a specific row and specific columns in data base file (Access) . You see , I am using a DataGridView control to show only SOME of the columns (fields) of a table from an Access file . For example , lets say that in the DataGridView control I only show the following fields :Field1 , Field2 and Field3 .Now , when the user selects an entry in the DataGridView control , I want to insert the text from Field4 into a text box on the form .
The problem , however , is that I don't know how to get the specific row in the data base file and also I don't know how to get the text in column (field) Field4 of that row .One thing that might be important is that the index of the row in the data base file is not necessarily the same with the index of the current row in the DataGridView control . This is because in the DataGridView control the rows are order by the contents in the ID Field .ol .
