User control event/viewstate missing during postback

User control event/viewstate missing during postback Question : Some of your web control's events goes missing or cannot be caught when you load it in a user control? Answer: Always use the Control.UniqueID generated for you by ASP.Net when assigning it to a NAME property of your control. The complete Control.UniqueId is available when you assess this in OnPreRender stage. Check your Control.UniqueID which is render into the NAME property of your control on a HTML page. ASP.Net keeps track of the control using Control . UniqueID which makes events / viewstate works. If you override your UniqueID (for javascript manipulation) you might get this problem. Why does it work on your Page but not in user control? On a page, when your control is renders, it probably use name like “MyControl” but in user control this is automatically change to “ctl$_MyControl”. ASP.Net is no longer able to resolve your control id if you override your Control.ID. For example, I created a...

SSIS package throwing "the type initializer for 'System.Data.SqlClient.SqlConnection'

SSIS package throwing "the type initializer for 'System.Data.SqlClient.SqlConnection' threw an exception" I'm running SSIS package which references an assembly which calls a WCF web service. Everytime i run it, i get this weird "the type initializer for 'System.Data.SqlClient.SqlConnection' threw an exception". So i decided to check on app.config setting in the following files located in C:\Program Files\Microsoft SQL Server\90\DTS\Binn folder. a) DTExec.exe.config b) DtsDebugHost.exe.config c) dtshost.exe.config It has nothing to do with these configurations. Solution Try installing Microsoft .Net Framework 3.0 (in my case) and it solve my issue.

TransactionScopeOption vs TransactionScopeOptions

TransactionScopeOption in System.Transaction What is the differences between TransactionScopeOptions when we use it to create TransactionScope. We have the following option at our disposal. 1. TransactionScopeOption.Required TransactionScope created here is dependent on the root TransactionScope. 2. TransactionScopeOption.RequiresNew Creates an entirely new TransactionScope 3. TransactionScopeOption.Suppress TransactionScope created here is independent of root TransactionScope. Code below shows an example of how transactionScope takes effect when you stop your application in s1.Complete(); Data gets committed in TransactionScopeMixRequiresNew and TransactionScopeMixSupress method but not TransactionScopeMixRequires. using (TransactionScope s1 = new TransactionScope(TransactionScopeOption.Required)) { TransactionScopeMixRequires(); TransactionScopeMixRequiresNew(); TransactionScopeMixSupress(); /// if you stop your application here /// TransactionScopeMixRequiresNew and Tra...

Ferdinand : Scalable Query Result Caching for Web Applications

Summary : Uses disk caching method to enhance performance for database application. Users connect directly to a proxy. Each proxy consist of STATIC web cache. These servers are connected to each other via DHT and commmuicate with each other using publish / subscribe infrastructure. If a request is in the cache, it is retrieve immediately. If not, it is query from database. Cache is expected to be huge, therefore disk caching method is used. Ferdinand uses database template request and offline analysis to gurantee consistency of data in database. Notification is sent to master group and everybody synchronize their data. Prototype implementation Apache as the web server. MySQL - webservier Ferdinand - custom JDBC driver Pastry - DHT's related task. Scribed - Publish / Subscribe component

Cloud computing and Data Analysis.

Daniel Abadi in Data Management In the Cloud concludes that cloud computing is more suitable for large scale data analysis as oppose to transactional based system. Thus more research is expected in this area. Part of the reason why are as follows:- 1. Transactional application does not necessarily adopt a share nothing model. 2. Maintaining ACID properties for transaction over cloud is complex. More research in cloud computing's database evolve around the following areas: a) fault tolerance - continue query execution in the advent of failure b) heterogeneous cluster c) easy of use
