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.

Here's the
CanTest = CanTest OrElse (DateTime.Now.Subtract(LastTest).Hours >= 1)
If CanTest Then
[code]....
However, when I change it to 65 minutes instead of 1 hour, it acts up. The time until next question starts going up instead of down... The only thing I changed is 1 hour to 65 minutes:
CanTest = CanTest OrElse (DateTime.Now.Subtract(LastTest).Minutes >= 65)
If CanTest Then
If InputBox(Question(Cur), "Question #" & cur.ToString("###,##0")) = Answer(Cur) Then

Is it possible to prevent any row in a grid from being highlighted? I'm familiar with the "SelectionMode" property. I manually add rows to a DGV and the 1st row is always highlighted. I'm trying to prevent this from happening.

In 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?

I am trying to find a solution, in eliminating repetitive string names, say for ex.,in a literal field, i am populating names of the contributor of certain article's history version, and so, if "ron" has contributed to the versioning of an article 3 times, the name "ron" gets added to this literal control, and outputs "ron" 3 times.

How 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.

I'm trying to create a COM User Defined Function automation add in for Excel 2003/2007/2010 and create a setup program that will install the add-in without the error message "Cannot find add-in 'mscoree.dll'. Delete from list?" occurring when the automation add-ins added to excel. This error occurs when running the setup program on PCs other than the development PC.
Using this example by Eric Carter combined with this Stack overflow answer. I have tried both methods of registering both the custom dll and mscoree.dll. Solutions for this problem are well described in both of those links however neither the registry edit of the setup program described in the stackoverflow link nor the code from the other link that should register mscoree.dll works for me when installing with a setup project on another PC (64 bit Windows 7 PC not used for building the program). (In fact the last comment on the Stack overflow link is a person with the exact same problem that I am describing here.) The add-in does work, I just want to prevent the error message.

When I deployed my project on a server, in certain circumstances, I get an error page that indicates I should create a custom error page. I was wondering how exactly I would implement this custom error page the server asks for to give me a precise and helpful message or preferably, how I would get the error to just display on the main page?This is the error message I got below
Runtime Error
Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.
Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".
<!-- Web.Config Configuration File -->
<configuration>
<system.web>
[code]....
Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's <customErrors> configuration tag to point to a custom error page URL.
