You can't block the users session - the only way that you could do this would be to have some mechanism where the user queries to see if they still have access to things. You may be able to do this with the Cache if you want to avoid the database.

Then only one think is could be done.... By checking every time post back, if user is valid.
Does server being overloaded if every post back is checked by using database?

hi guys
i am having a asp.net application which is done in .net 2003 version, the problem here , i am having a text box with a range validator control for that.. when i changed controltovaliate property of the validator , the size of all the tables in the asp.net page is getting changed ,,such that the alignment is totally collapsed .. i have no idea how the sizes of tables (height and width of tables are dynamically changed)
regards
winnie

That's normal behaviour for tables. The size of the cells in a table are calculated from the size of the content in the cells. If you put something in a cell that is larger than the previously calculated size, the cell will grow and the other cells will be resized to give it space.

Almost everyone that post here, does so because they can't find a solution. That doesn't make everything "very serious".

Not without knowing anything more about how you use the tables.
My first advice would of course be not to use table based layouts. They were great ten years ago, when there were no alternatives. Compared to the alternatives available today, they suck.

Make them fixed width. Oh yuck - I can't believe I just recommended that. Seriously though, if you don't want the sizes to be recalculated you have to make them fixed width.

You could set the validator Display property to "none" and use a ValidationSummary so you can move the error message into it's own table. This way, it's display doesn't affect your control layout.

You can test the retrieved data against DBNull.Value and act accordingly.

hi
i think is better you remove allow null in your table and then set a default value such as '-' for when is not any thing for insert.
now you can simple manage your request.

You can use Coalesce to return a value only if previous values were null.

Thanks for reply but

Thanks.

You can, for example, do this:
select coalesce(Name, '-') from table
I think the syntax is correct. This would return - if Name was null for a row.

Hi,
How do I remove references from my BIN folder? I added a reference, now I don't want to use it, so I deleted it manually, but when I build the website then it still goes and adds it.
What I did was I had Enterprise Library January 2006 installed. I removed it, and installed May 2007. Now when I build the website, it over wrote the 2.0 dlls with the 3.1 dlls.
Regards

I think you should remove it from project first go to bin folder of your application Explorer window then delete from there it will alos get deleted from project and bin folder
Thanks and Regards

You have to make a little change in your code..
Code:
=====
Remove this code
---------------
TextBox1.Text = str
Apply this code
---------------
1. Take a one image html control on the form. like.
2. In the server side , Write this code..
MyImage.Src = server.mappath("" + str);
Hope this will help you,
Regards,
Abhi

Thank you Abhi, but image control does not have Src property. I can open a picture file using imageurl property. But how to open other files?

Where are you storing the uploaded files at server ?
if you want to open any of files then these files should be in current application Virtual directory or another virtual directoy
