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'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.

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

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 .
I have search system that works like charm: 1> Searches specific folder for text files which contain specific word 2> Puts those text file names and/or paths to listbox However i want it to put (instead of InputStr) the specific line where word is found in text file to listbox.
