Hello World to C# Threading Part 1

In this post we will see how we can implement simple threading. Why do we need threading? When you want you application to do more then one thing at same time, then you need to implement threading. One usual and common scenario would be when your application needs to get data from some other resource like web services and you don't want you application GUI to be freeze during this time. In that sort of case you will run the code to access web services in separate thread so your application GUI won't freeze. The System.Threading namespace .NET provide interfaces to implement multi threading.

Threading in C#

What is Threading?
-Parallel execution of code pieces on CPU, commonly compiled codes started in a single thread but it is possible to create multi-threads within a program.


Multi-core processors are new standards on the user's hardware. By taking advantage of the multi-processing capabilities of these machines you can achieve significant performance upgrade with some minor changes in your code. When an application does not make use of threading techniques it is wasting valuable resources. This tutorial will cover the basic threading concepts and threading methods and properties.

Multi-threading in .NET: Introduction and suggestions

This article uses the C# type shorthands throughout - int for Int32 etc. I hope this makes it easier for C# developers to read, and won't impede any other developers too much. It also only talks about the C# ways of declaring variables to be volatile and locking monitors. Developers using other languages can find the equivalents in their own preferred environment, I'm sure.

Inserting personal error message in ValidationSummary



I am creating a web form that requires a lot of validation. I use many of the validation control in asp.net already like RequiredFieldValidator and CompareValidator. 

My Problem: after my custom validation for the value entered return an error message, and I pressed enter key when the field is empty, my custom error message is overlapped by my ValidationSummary. 

Setting my custom error to visible = false on button click also does not seem to work as it requires for me to enter the value first.

This made me think, is there a way to insert my custom validation inside the ValidationSummary as an error message like for other validation control?

Thanks in advance

UpdatePanel is not a known element - message when upgrading to 1.0 ajax


It worked on one of my old pages.  I change the web.config, renamed all the <asp.

On some aspx page it doesn't recognize the updatepanel.  It only does on one page.  If I create a new aspx page with a different name - then it works.

Should I just create a new web project ajax - then copy all my code into there?  Or is there a way to get those old pages to recognize the new ajax controls?

Very Basic Question - Error message running first page


Hi Everyone,

I am running Windows 7 and I have gone into Control Panel and activated all of the IIS Functions.

The web application I am running was downloaded from the net (and has worked on other machines previously).  Once I downloaded it, I moved it into C:/inetpub/wwwroot/code/main.asp

I am a bit of a novice at this!  But I am hoping someone can point me in the right direction!


I get the following error when I try and run the web application through IE:

"An error occurred on the server when processing the URL. Please contact the system administrator. If you are the system administrator please click here to find out more about this error."

(When i click the "click here" button it just goes to the IIS site).


Appreciate any help I can get!




Multiple Paramatized Threading issue


I need the funcitonality to have two methods run concurrently of each other and the parent thread (aka the method that makes these two calls) to halt until BOTH are done. After the threads are done, I need to perform logic on the returns of the method, so it is essential for both of them to be complete before the parent thread continues. I have searched the internet and tried varous attacks, and I always come up with the same result, this being the parent thread continues operation after the first thread finishes, leaving the second thread running.  Can someone show me a quick example of how I can do this. I have tried checking states of the threads, halting the threads, but I always end up with the same thing. Any help would be great. Thanks.

Any idea on how to perform this?
