Reading XML And Storing In Variable?
May 18, 2011I am trying to retrieve a 'tag'(Is it called that?) from an XML webpage. Once I make a post request from my vb.net app it sends a command to my online webserver and redirects me to a page that has entries that change each time. The page that im redirected to that changes each time looks something like this:
<mainpage> <id>hello</id> <random>176</random> </mainpage>
What vb.net code would I use to retrieve the id (In this case 'hello') and store it in a variable.
Reading In More Than One Variable From Each Line In A File?
Mar 1, 2010Trying to read in three variables per line from a text file that looks similar to the first code segment. What we've been taught so far to read in is something similar to the second segment. And it works all and good for single words per line.
If this was C++ I'm pretty sure I could getline and use the comma as a terminator, but I'm not sure if a similar function exists for VB.

View 1 RepliesReading The Contents Of A SQL Server Job?
Sep 24, 2010I am writing an application that will call a SQL Server job on all our client's systems. I'm able to execute it, and wait until it's finished. It has an output file that's save location is hard coded into the job however, and this is not the same location on all client's.
Since the job is identical on systems minus this one value, I want my code to read in the script of the job and parse out the location.I'm having trouble figuring out how to get the actual text of the job itself.
Is this possible in .NET? If so, how?

Communications :: Reading Exchange Server Emails?
Oct 28, 2004I am writing an application to grab attachments from messages in a particular folder in an Exchange server account and then process them. The processing of the attachments should be no problem, but what I don't know how to do is to connect to the Exchange server and access the messages.
What I would like to know is what references and imports I need, and how to access the various objects in the object model. I have been looking at CDO already, but I have had problems finding help on the Internet that is relevant to VB.NET.
For example, I'd like to know how to create the Exchange object, log in and navigate to the folder that has the relevant messages in it.

Using The Response Code From A TCP Server As A Variable?
Mar 12, 2012I'm writing a program that will be based off of TCP communications with a server. The user would click a button, which would send data through TCP Client to the TCP Listener on another computer. The TCP Listener sends back a response, and the TCP client is receiving it. Right now I have the response from the server showing up in the immediate window, which is good. I want the response from the server to determine what action the client program will take next.
How do I use the server's response variable in a different class? I need to use the response from the server in an if-then-else statement to say "if the server response is 001, then execute this code. else, if the response is 002, then execute this code."
Client/server - Can't Access Communication Variable?
Aug 14, 2011I have a client/server program. There is a variable called readData that takes returndata and places it there. My question is, why can't I access this variable directly, for instance, varC = readData and then try to access a piece of it i.e. textbox1.text = varC(2), I get an error "object reference not set to instance of an object". Why is this happening? It is because the readData is a networking 'component'? How do I get around this? I can post more code from the server app if needed.
