How to find pen drive hidden folder

Sometimes due to virus attack, our pen drive data is hidden.  We think, all folders are deleted.

To find hidden folder in your pen drive. Just run the following command in your command window.

attrib -h -r -s /s /d g:\*.*

Error: Sys.WebForms.PageRequestManagerTimeoutException The server request timed out

Few days ago I found an error when tried to export about 500 reports to pdf.  The error is Sys.WebForms.PageRequestManagerTimeoutException The server request timed out. This is not found as exception. It is found on run time as javascript error.  I was working on Ajax Control tool kit 3.5. It is occurred because export operation of 500 reports to pdf were relatively long time than default

AsyncPostBackTimeOut.

How to solve this problem?

AsyncPostBackTimeOut is a property of ScriptManager of Ajax. You can change time out length. To solve this problem I have increased the time out of AsyncPostBackTimeOut property.

For example, for exporting 100 pdf I need 20 minutes. So, I will use maximum time out limit 20 minutes which is exactly 1200 seconds. My code is like below.

<asp:ScriptManager ID="ScriptManager1" runat="server" AsyncPostBackTimeOut="1200" >

asp:ScriptManager> 

**The default value of the AsyncPostBackTimeOut property is 90 seconds.

For long time running method (Suppose a method will run for more than 90 seconds), you should use web service by setting timeout (number of seconds) of that web method by Javascript.

This application was precompiled with personalization turned off, but it appears to have been turned on after the precompilation, which is not supported.

Exception Details: System.Web.HttpException: This application was precompiled with personalization turned off, but it appears to have been turned on after the precompilation, which is not supported.

I did not include Source Error and Stack Trace here. So, what is the solution of the problem?

Yea! I have solved the problem by adding  the following snippet in web config.
