crash test on my website resolved exception - ASP.NET Discussion Boards

I would take the time to learn about the XmlTextWriter. It made my life so much easier when I had to create an XML file for integration with another system.

Use this to get started ...

Dim writer As New XmlTextWriter(sXMLPath & sXMLName, Nothing)

 'Use automatic indentation for readability.
writer.Formatting = Formatting.Indented

'Write the root element
writer.WriteStartElement("REPORT")
writer.WriteStartElement("FORMULA")
writer.WriteElementString("FORMULA_ID", sField0)
writer.WriteElementString("FORMULA_CODE", sField1)
writer.WriteElementString("VERSION", sField2)
writer.WriteElementString("DESCRIPTION", sField3)
writer.WriteEndElement() ' close formula
writer.WriteEndElement() ' close report


'Write the XML to file and close the writer
writer.Close()

I have a gridview control inside of a panel. The panel has scroll bars set horz and vert. I want all column headings and column text to not word wrap. If I turn off word wrap for column headers and items it still word wraps. How do I get word wrap to work?

Try putting the grid in a table and applying the style setting:

style='table-layout: fixed;'

hello,
in order to test the stability of my code i tried to crash it and unfortunatly i succeeded.

what i was testing is to see what will happen if i click a 'post button' many times

this page i tested has input arguments along with validation.

is there a solution for this or shall i use the 'ugly way' and disable the button until next postback ?

here's the exception :

Server Error in '/' Application.

tnx in advance

Not a solution for an internet app but you could disable event validation.

...the only way I know is to disable the button.

Take a look at my corner of the net at Code Research Center

yeh... well how can i trap this event ? i want to 'handle' this unhandled exception..

Or take the 'ryanair' approach - "Clicking this button more than once might result in the purchase of several flights..."

... or you can say "click only once, its not a shooting range"

Hai Guys,

Find either the first Sunday of '09, or the last Sunday of '08 (depending on how you want to count that) and add 34*7 days.

In my aplication I've to trace logged in and logged out for an user. I've created a table that contains information about logged in and logged out time of an user. whenever an user logged in i simply add a record in this table and when user logged out i simply update this table. now suppose that when a user close its browser by clicking on cross icon of browser or after a session time out then in this case user logically time out. then in this case how i update table for user logged out?

Handle the Browser Close using Java script, Open a popup on Browser close and in the code behind, do the server side stuff for update the data and then close the popup.
This will resolve your issue.

thanks. on which event will i have to call method DeleteUserLog?

if you have the master page you can call it on Body Unload if you dont have the master page you have to give it on body unload of all form (If page number is very less ) other wise developed a Handler to do the stuff.

Cheers !!

hi. i have put this code in window.onload event: window.event.clientX < 0 && window.event.clientY <0 and on clicking browser's close button we always find window.event.clientY < 0 and window.event.clientX > 0. so i'm unable to track browser's close event.
