Yusuf,
I know that is what I need to do but my question is how do I go about doing that. If I am updating the database then how do I know that the user has not just closed the webpage instead of loging out.
Do you know what I mean?

I don't know your level of asp.net competency, but your question is a bit silly
- Session_End signals the session is expiring, has nothing to do with user logging out or browser closing
- Browser Closing - There is no way you can detect this from the server. You can write some js to detect browser closing ( mind you there is no browser support for this, all is behind the door hack)
- user logout - the user clicked on logout, so you know that, don't you, don't you....

Hi,
I have created a string using StringBuilder class. This string is an xml.
Now my question is that how do i pass this string to xmlTextWriter or XmlDocument class to get the correct format of the string ?
I don't want to start creating the xml using XmlDocument class or XmlTextWriter as it's really cumbersome to nest the xml in it. It's all done using StringBuilder and now i just have to correct the format of the string..
Any idea ??
Thank You
Andyy

XmlDocument has a method LoadXml that takes a string.

ok for instance,
testStr is StringBuilder type with having complete xml stored in it.
Now can you please show me the syntax, how can i pass this testStr to XmlDocument to get the correct xml format output.
Thank You

What are you trying to do exactly? I thought perhaps you were trying to validate the xml, in which case you could by trying to load it.

What does that mean?
|
|

|

basically xml is stored as a string using StringBuilder which ends up with non xml format and hard to read. So one way is that i fix the format manually which is again a pain. So i am asking if there is any second way which can correct the format of the string as xml.
I hope it's clear now.

So you want pretty XML? Load it into an XmlDocument, then use either WriteTo or WriteContentTo (I forget what the distinction is) to write to an XmlTextWriter. The XmlTextWriter can be configured for indentation. The XmlTextWriter will need to use an underlying stream, just use a MemoryStream for that. You should be able to read the result via a StreamReader.

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.

Not a solution for an internet app but you could disable event validation.
...the only way I know is to disable the button.
|
|
|
|
|
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"
