Set The Three Textboxes Text To Different Variables Using Only One Line Of Code?
Dec 18, 20101) Lets say I have three textboxes: TextBox1 TextBox2 and TextBox3.
Public Sub loopthing (ByVal input1, ByVal input2, ByVal input3)
For i = 1 To 3
TextBox(i).Text = input(i)[code]....
I know that the (i)-thing will not work, but my question is if it's possible somehow to set the three textboxes text to different variables using only one line of code (Like my attempt above).
2)How can I do so that when I click a tabpage on runtime, a certain textbox is highlighted and ready to write without a mouse-click?
I've tried the tabpage's GotFocus- and Enter-events, and writing
TextBox1.Select()
there, but it only works the first time I enter that spesific tabpage.

View 15 RepliesDefine Some Global Variables Of A Class - Variables Occupy Memory?
Mar 23, 2012I define some global variables of a class as follows:
Private Class MyClass
Private var1 as Decimal
Private list1 as List(Of string)[code].....
But I found that after this form is closed, all above variables, var1, list1, list2 still exist in memory. I thought they should be collected by gc since the form is already disposed as I confirmed.
Add: I have monitored half an hour after the form is closed. But these variables are not collected by gc. I have an automatic update procedure on the form which uses above variables.Since the above variables still hold values, the automatic update procedure is always called which causes exception. (One quick fix is to check if form.isDisposed in update procedure. But I do not think this is elegeant. Besides, these variables occupy memory.)

Mar 8, 2011Question 1: What is the difference between "Background Worker" and "Worker Pool" as indicated within the MSDN samples provided.
Question 2: I noticed while using, AddressOf _Function_, variables cannot be passed; what would be an efficient solution to this?
Question 3: While using multithreading is it required to invoke before setting variables, or only form properties?
Question 4: While using System.Net.Sockets is it safe/efficient to use Application.DoEvents while waiting for new data; or would be using a Do While loop be fine without DoEvents since the action would be multithreaded? Note: there can be up to 2000-3000 sockets in use at a time.

Parsing Multi-line Clipboard Text Into A Single Line And Pasting Into A Textbox?
Feb 7, 2011a user copies multiple lines of text (say, from an email) into the clipboard. Based on my observations, when one tries to paste the text into a single-line textbox, only the first line is actually pasted in. (I am aware that the "obvious" solution would be to set the Multiline property to True, but there are reasons I am looking to avoid this and to put multi-line data into a single line.)
In the TextChanged event handler, I wrote code that parses the clipboard data to successfully convert it to a single-line, comma-delimited format.
