View 1 Replies.net - Value Of Global Variable Won't Change
Dec 22, 2011I 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.
[code]....
Here is the entire source code:
Module Module1
Public strDataValue = frmTest.txtDataValue.Text
End Module
[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.

Global Variable Across All Machines?
May 31, 2009I'm focusing on Networking programming and I had found something that was very interesting to me in Remoting, which is the ability to have some how a "shared global variable accross applications" ... Here's a quick example of what I'm saying (which is stripped and modified from one found example on internet):
In the Remoting class:
Code:Namespace remoteclass Public Class xx Inherits MarshalByRefObject
Public Shared_Var As String 'This is our share variable
End ClassEnd Namespace
[Code]....
I found that I can eaisly use this red-marked variable (Shared_Var) acrross all application clients without any extra line of code to update its value ... without using even what is called "singlecall" and "sigletron".
But I have concerns:
1) This is only applicable for simple types of variables (e.g. string and integer) but an array or DataTable for example are not updated! and I don't know why!!
2) Would that load the communication network (I mean the content of these shared variables (few KBs to 1MB) will always be communicated across machines all the time without any management) ... Actually I don't how this works from inside, Does it update on change or cyclic ...
3) And finally, can I found something like this in WCF?
Global Variable In Asp.net Website?
Dec 22, 2010I'm wanting to declare a variable as below for use in several pages on my site. I assume rather than declaring it once per page I can do it globally? I've tried it in a class (app_code folder) and in the global.asax page but my code can't seem to find it. I may be going abo9ut it all wrong though? Code as below...
Dim myUser As MembershipUser = Membership.GetUser()
So basically as it stands my pages can't find the 'myUser' variable.
Global Vs Local Variable
Mar 22, 2010I'm writing a subneting calculator in VB.NET.I'm using the IDE SharpDevelop.Well my problem is I'm using a function to do some calculations and then to figure out the class of the IP addresses.Well I pass a variable from the subroutine, that is accessed when a button is clicked, to the function then the variable is passed back to the subroutine and then the variable is passed again to another function but when it reaches this second function it doesn't retain the value it was given in the first function.I'm not sure if I'm just passing the variable wrong or if this is how it works.I know I can make this work probably by using global variables but I'm not sure if this is proper. So my ultimate question is what is the difference between local and global variables besides just scope and should I try and use one more than the other.
View 4 RepliesHow To Define Variable As Global
May 14, 2009I have no idea as to how I can define a variable as "GLOBAL" in VB Express 2008. I used VB V 3.0 and if I remember correctly the statement "Global varName as Integer" allowed me to use the variable across different forms. I've tried the statement "Public varName as Integer = 0" on Form1 but Form2 tells me the variable is not declared.
The statement (in Form1) "Form2.Label1.Text = CStr(varName)" displays the value on Form2 in Label1 but I cannot then use the value again in Form2, e.g. "Label2.Text = Label1.Text". How I can transfer a variable value from one form to another and manipulate that variable in the second form?

Assigning Variable To A Label In Global?
May 11, 2011I'm working on my final for VB.NET, and maybe it's just late...but here's how it goes. I need to make a variable named intMoney and it will be used to keep track of how much money you have and the value will be displayed in a label. Since this 'game' will have a lot of things going on, it needs to be available in a lot of places, not just one click event.
But I need to set intMoney to a starting value of 200 and then assign intMoney to a label called lblMoney. I can't assign intMoney to lblMoney in global. I get build errors. Where should I put the lblMoney.Text = intMoney?
