Serialize Two And VB Returns "local Variable Is Already Declared Within The Current Block?

May 17, 2011

I've used this code before but only when I was serializing one array. Here I'm trying to serialize two and VB returns "local variable is already declared within the current block."Someone tell me how to do this correctly, pleases. I'm banging my head against a brick wall that I can't see.

Object Variable Or With Block Variable Not Set - From Property Get With Bindingsource.current?

May 31, 2012

Now I have the need to get a current value from a bindingsource in a property of a user control.In a previous thread I had tracked down the "Object variable or With block variable not set" to the return in the Get block of a property. At the time I was only using the Set so I just commented out the offending code until I needed it.

[Code]...

The error does not occur during a system compile, only upon saving the container object of the user control. As I said the Set works correctly, only the Get causes the error.I would like to know what I am missing/misunderstanding and am open to other suggestions of handling retrieving the current value of a bindingsource in a user control.

IDE :: List All The Local Variable Used Inside The Current Function Or Sub?

Aug 12, 2010

I have a button inside a one of my forms which contain a lot of coding and normally a lot of variables declaration.

Is there is a option/add-on that I can use/set that enable me to display all the variable used inside the sub or function I am currently working in?

All I can find is add-on to display the Properties/Methods and only Public variables inside the form or inside the class. but I need to list the local variables also.

VS 2010 Compiler Creates New Variable Automatically When Use If Statement Without Strictly Declared Variable?

Jan 10, 2011

Say that i have the following code that parse about 20k records from the DB.

Code #1

vb.net While reader.Read()
list.Add(If(Integer.TryParse(reader(0).ToString, 0), Integer.Parse(reader(0).ToString), 0))
End While

And then another code which does the very same thing but it seems to be a little cleaner.

Code #2

vb.net While reader.Read()
Dim storeowner As Integer = 0
Integer.TryParse(reader(0).ToString, storeowner)
list.Add(storeowner)
End While

This is what i am confused about; does the compiler creates a new variable automatically when i use the if statement without strictly declared variable? What approach is better in sense of performance?

Variable Naming Conventions To Illustrate Variable Type And Where Variables Are Declared

Aug 24, 2009

I am looking for a good resource on variable naming conventions to illustrate variable type and where variables are declared. So I will have public variables, Private variables, private or local variables. I also may want to declare variables with the same name in different class code (i.e. in the code behind different forms). I am assuming good coding would dicatate a prefix for declaration location.

Variable Hides A Variable In An Enclosing Block?

Nov 17, 2009

I have written a program and I think it is fine except for one error. "Variable 'intIndex' hides a variable in an enclosing block". i have a feeling this is something easy but have been trying to fix it and have failed miserably. I'm surprised I have any hair left!

the program is a simple hangman game that lets player one select a word from 1-10 letters and the other player needs to guess within 10 guesses.

Option Explicit On
Option Strict On
Option Infer Off

Use Variable In A SQL Query - Says - Variable Is Not Declared

In one function I have the variable: dim StrProjectNumber = UCase("23-EXP-16284")

However in another form I want to use that same variable in a SQL query, and when I try it says the variable is not declared. Do I have to make a global variable or is there a way around it? If so, how would I go about declaring a global variable?

.net - Should Events Be Raised In New Threads To Not Block Current Work?

Dec 15, 2009

I'm currently designing an assembly that will be used by third parties. One of the classes has a long process of TCP connections and it informs about its process using events. For example

''# Do stuff that takes some time
RaiseEvent CompletedFirstPartEvent()
''# Do stuff that takes some time

[Code].....

What I've seen if that if the handler of one of those events takes too long (or even worse, it blocks) I can have timeouts and it's hard for the developer to see that one class is not working fine because his handler is taking too long.

I was going to fire the events in a new Thread to avoid this issue but this looks strange to me because I've never seen something like that, what I've seen until now is the developer spawning a new Thread if his handler was going to be timeconsuming. So the question is:

What would you do? Create a new thread or force the user to create his own thread? (Or is -there a better approach that I don't know?)

Keyboard Shortcut In Visual Studio To Select The Current Block?

Oct 26, 2010

In VB Classic, VBA and also in Visual Studio you can dbl click close to the left hand margin of a block of code and it will select the whole of the current block (sub, function etc). In Visual Studio this clickable area is adjacent to the line numbers on the left.Is there a keyboard shortcut that will do the same job? that is, select the "current block".
