I was wondering what the easiest way is to get a portion of text from a string for example, you have:
"example1,example2,example3"
And i need to be able to get all three of the items separate:
"example1"
"example2"
"example3"
The length and number of items will change, I'm using a listview subitem
I am trying to extract the first portion of a string up to the first SPACE or any non-numeric digit.I thought I could do it but the string may contain an alphabet in the front followed by varying digits of numerals, making it more complicated.Here are some examples of the string to be parsed and the expected results:

I would have to use a series of instr statements but the code would be much cleaner using RegEx.
I have a combobox which is filled with items from a table like this: [Code] What Im trying to do is to when I choose one name from the dropdown list the firstname shall go to one textbox1 and lastname go to textbox2. One way doing this may be to use the ID column wich is the the Primary Key. And do a new search in a button with that ID which fills the textboxes. But how can I get just a portion of the selected string in the combobox to a string so I can do a search on it.

when i run code after 60 sec it display following error what is this error and how to eliminate? ContextSwitchDeadlock was detected Message: The CLR has been unable to transition from COM context 0x2040a8 to COM context 0x204218 for 60 seconds. The thread that owns the destination context/apartment is most likely either doing a non pumping wait or processing a very long running operation without pumping Windows messages. This situation generally has a negative performance impact and may even lead to the application becoming non responsive or memory usage accumulating continually over time. To avoid this problem, all single threaded apartment (STA) threads should use pumping wait primitives (such as CoWaitForMultipleHandles) and routinely pump messages during long running operations.
View 1 RepliesIn ASP.Net Web Forms there are cases that I've come across that create order dependent code. As an obvious code smell I'm looking for solutions to solve this problem.
A pseudo-code example would be: Calling Code :: Page.aspx
protected void Page_Load(...) {
var control = LoadControl("ControlX.ascx");
// Ugly since the control's constructor is not used by LoadControl
control.SetDependencies(...);
[Code]...
LoadControl has two signatures, the one used above accepts a string for the control classes physical location and correctly creates the child controls. Whereas the second signature accepts the control class as a class type, and any parameters for the constructor, however the child controls are not created as detailed in TRULY Understanding Dynamic Controls.
So how can I eliminate this order dependency in the cleanest way? My first thought is that if I dynamically created the child controls in ControlX, but then that can be cumbersome for larger controls.
So basically I'm making a BINGO game on vb 2008 and i have a "call number" button. The letter and numbers get added to a list box each time. But i do not want the same number to be called. Is there a way that the program can read the items in the list box and not generate (Randomly) the same value again to be displayed in the label.This is what i have:
Callnum = Int(75 * Rnd() + 1)
lstNumbersCalled.Items.Add(lblCallLetter.Text & " " & Callnum)

I have a text box where I only want to be able to enter each character once, so no AA or 99, only one of each character. This is so I can paste into the field, but where any duplicates would be eliminated. I've tried using this code, but am not sure where I go wrong.

I have written a number of classes in my time in VB.NET which set the basic elements in a custom New constructor through parameters. This makes things easier and enforces discipline. However, using Public Sub New() becomes pointless. If someone else tried to use this class, he or she could make a mess of it all by using Sub New without the arguments. I'd like to remove this method but I haven't found out how. I could make it raise an exception, but that somehow seems unseemly. I'd like a neater way. Does anyone know how?

View 5 RepliesHow to get rid of all the buttons - or boxes - on a form's caption bar without actually eliminating the bar itself? The closest I've gotten is setting the FormBorderStyle = FixedToolWindow, but that still leave a close button ('x'). If I set the control box property = False, that get's rid of the bar itself. I want to the users to still be able to grab the bar to move the form around, but not to minimize, maximize, or close via the caption bar - only the buttons I have on the form. It's always difficult when user's want something that's not standard windows design.

I have a panel with the BackgroundImage set that I'm using as a button. The panel also contains a PictureBox with a png image loaded so that parts of the image are transparent and the panel image shows through. On MouseDown I change the panels BackgroundImage, then on MouseUp I change it back again. The problem is that when the panel image changes, the PictureBox flickers badly when redrawing its transparent areas. I've tried using the DoubleBuffered property of the form its on; no luck there. I've also tried SuspendLayout just before changing the image, refreshing the PictureBox, then ResumeLayout. Still no luck.
