Using The Response Code From A TCP Server As A Variable?

Mar 12, 2012

I'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."

Runtime Variable Field Selection In Code Behind?

Jan 23, 2012

I have a list with several fields that is created from dataset from a linqtosql query. At run-time, the user gets to specify what field he/she wants to display from the list. In other languages, I can dynamically do this like:

valueIwant=mylist(i).[fieldnameImInterestedIn]

Where 'fieldnameImInterstedIn is itself a variable. How do I do this in VB.Net?

non-working actual code follows:

Dim patientdata = (From patientvar In pdfdatacontext.tbPatients Where patientvar.PatientID = patientid)
Dim patientlist = patientdata.ToList()

Variable Type - Move Code Outside The If Statement As It's Performed For Each If

May 17, 2012

As you can see from the code below there is a lot of repeated code. I want to move that code outside the if statement as it's performed for each if, but the Dim employees variable I'm declaring is causing my issues. I don't know how to declare the variable outside the if statement as it's a linq-to-sql query, so I can later define it within the if statement. I can't access employees outside the if statement, so I can't just put the repeating code outside the if statement.

Private Sub btnFindEmployee_Click(sender As System.Object, e As System.EventArgs) Handles btnFindEmployee.Click

VB 6 Code Conversion To VB Express - Warning: Variable StrEncTemp

Nov 24, 2010

I am converting a VB6 program to VB express and am having a couple of problems. One of them is a problem with the variable "strEncTemp". I have the warning "Variable strEncTemp is used before it has been assigned a value", and I can't assign a value to this variable without creating issues. It also seems that a null value is being returned and the code produced by this routine is corrupt. This seems to be the last issue I have in converting the code. I tried setting it to 0 but it then shuts down the program with an error. This is the portion of code that has the warning and produces a null value. [Code]

Why Wouldn't 'Select ... Case' Execute The Code When Using A Variable

Global Variable - Test And Production Code In A Case Statement

Jun 3, 2009

I have an application that contains both test code and production code. The test code points to the test files on the local machine while production is located on the server. I comment out the production code when testing. To save some time I figured I would create a Global Variable integer called pTest and encase the test and production code in a Case statement so that if I set pTest=1 then the test code will run and if pTest=0 then production code will run.

Commented Code Won't Work - Time The Thread Start, The Variable CurrentFarm Have Changed.

Vb.net For each currentFarm in ......

If urlQueue.Count > 0 Then
Debug.Assert(currentFarm.isBusy = False)
Debug.Assert(currentFarm.WebClient.IsBusy = False)

[CODE]...

The commented code won't work. That's because by the time the thread start, the variable currentFarm have changed. So I create a new function and cache the currentFarm in the function parameter. No there will be a cache of currentFarm address (object is always a pointer) on a stack and that address is the one being passed to the System.Threading.Thread constructor.
