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.

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,

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
