hi.....I have written in button click event a complex code

button_click

'complex code

response.reditect(error.aspx) 

end sub

this code works fine................but when i am adding try and catch and ex as exception.that time one exception is generated ..(Thread is being aborted).

But without try catch statement.the code wortks finee............

so how to avoid that exception as i have to write try ,catch startement..............

Response.Redirect("somepage") will throw ThreadAbortException and will be caught if you are using the Response.Redirect inside a try catch block. To avoid the exception you need to pass in the endResponse (= false) value using the other overload of the Response.Redirect so that the current executing thread will not be aborted.

Try
	Response.Redirect("error.aspx", False)

Catch
End Try

Thanks

Nice Answer.its working fine,............

II have another question.......How do i go for exception handling for a project..............can u give any suggesting.......like i will create  a page....

databse connection  error

case 401

network error.....

cae 403

file not found

Or is there any better way.........

Kindly give ur suggestion BRIEFLY..........Thanks once again for the answer u gave..........

Its tough to know what kind of exception will be raised, lest you would sure avoid it. Also you cant write for all the cases, as there are numerous exceptions that can be raised. One good way is General Exception Handling

Hi Suryansu,

e_screw has given you the right answer for the original issue. It would be best if you open up a new thread for the new question. In this way, our discussion here will not deviate too much from the original issue. This will make answer searching in the forum easier and be beneficial to other community members as well.

For the new issue, I think we can use the statusCode and redirect element in customErrors section. For example:

How to: Create Web.config Files (Visual Studio)
http://msdn2.microsoft.com/en-us/library/k8x4ket8(VS.80).aspx

        <customErrors mode="RemoteOnly" defaultRedirect="GenericErrorPage.htm">
            <error statusCode="403" redirect="NoAccess.htm"/>
            <error statusCode="404" redirect="FileNotFound.htm"/>
        </customErrors>
