I installed the latest version of Process Explorer (v12) on my Vista 64-bit computer and set it to replace the default Task Manager, however, when I right-clicked the task bar to launch Task Manager, Process Explorer did not come up but an error message saying cannot find taskmgr.exe file: Windows cannot find ‘C:\Windows\system32\taskmgr.exe’. Make sure you typed the name correctly, and then try again. The old version of Process Explorer does not have this problem. […]

As shown in my last post, Firefox 3.6.2 didn’t pass the Acid3 Test with a score 94/100, 6 points away from passing the test.

The result showed that Firefox 3.7 Pre-release 4 did do a better job than Firefox 3.6.2, but unfortunately it still didn’t pass the test, having a score of 96/100. […]

However, ISO 8601 format is support […]
In my previous post, I discussed how to use TransactionScope to update DataTable objects in a transaction. The biggest shortcoming of using TransactionScope is that several security settings on the server need to be modified in order to make it work, and this may not be feasible for many companies because of the security concern. Today, I will discuss how to use XML and stored procedure to update DataTable objects in transaction. The basic idea […]
We all know that if you need to insert/update data in several database tables that have relationship with each other, then you will need to make sure the insert/update process is completed in a transaction to ensure the data integrity. With stored procedure, it is not hard to perform transaction, but what if you are using DataTable? In this post, I will show how to use TransactionScope to implement transaction for DataTable update.

How can I accomplish this? I wrote an article on Experts-Exchange.com regarding this question and here is the link to it: Display confirmation from code behind before continuing a process […]
