View 5 RepliesWhat happens if I do: Dim x As New Int32? Is a object of int placed on the heap? If it is, maybe your application would be able to access global variables faster if they were reference types.
A global variable as an value type should be somewhere at the bottom of the stack most of the time and it might take more time to get to this then to get a object from the heap. Unless it's the same story with the pointer of this object is also at the bottom of the stack of course.

Dim strpro2 As String = txtpro2.Text

I have been working on an activeX control which works on serial port communication. Now I have completed the project and created its setup.exe using Visual studio 6 -> Tools -> Package and Deployment Wizard. Then I installed the control in another PC and in a new project included the control using project -> components. But when I click on the control in the toolbox and then include on the form it gives the following error : delete current link ? and on clicking OK, nothing happens. I tried searching a lot on google but didnt find anything. Another problem is that I have created a string array as a global array which can be accessed by all the methods.I am able to include the same activex control in my own pc when I have created the project. Here it works fine, I am able to access all the methods that I coded in the control, but the String array mentioned above can be accessed in other project. I tried writing Public before the array declaration but it give me the compile error : "Constants. fixed length strings, arrays, user defined types and Declare statements not allowed as Public members of object module."

I have a variable whose scope needs to be global, because it needs to be called in a function as well as in a button press. So I declared the variable in a Module so it would be global.The problem is that the value of this variable needs to be equal to the value of the text property of a textbox in the form.You enter a string into the textbox, in this case I entered "Hello". Then you click the button and it displays what you wrote.You click OK in that message box and change the value in the textbox. In this case I changed it to "Goodbye". Then I hit the button again, but the variable did not change values and the messagebox displays "Hello" again.

Here is the entire source code:

Note: This is just a demonstration of a problem I'm having in a much larger program so the variable does have to be global.
If we declare a global variable in module in vb.net, we can use that variable in anywhere in project.
How can we achieve same thing in C#.
Previously when we tried to convert a vb.net project to C#, we succeeded in removing the syntax error but we can't access global variable in a form.
I need some solution or guidance. Where I am making a mistake?
I need to add the code below to my global.asax file. It begins with a Sub Application_BeginRequest . My global.asax already has a section that begins with Protected Sub Application_BeginRequest(ByVal sender As Object, ByVal e As System.EventArgs) I'm assuming that I should not have two sections with Sub Application_BeginRequest I tried putting the core of the new code into my existing Sub Application_BeginRequest and it returns no errors but it when I try to view the website in VWDE 2010 it times out. Something is causing it to run or load slowly.

When I declare a variable as public in a module I never have to specify the name of the module to access the variable, so why do I need to do it for a dataset? The code in my module is:
