I'm sorry, but now it gives me this kind of exception:
System.NullReferenceException was unhandled by user code
Message="Object reference not set to an instance of an object."
Source="App_Web_p-lbdwwh"
Thank you

It gives error becoz ur quiry string is null.
check condition first
if(Request.QueryString["id"]!=null)
{

Can you put the break point there and debug the code..to see if there is any element in querystring collection or not?

Yes, it shows the value of UserID, but doesn't assign it

You can create a bitmap image from image path you have stored in sql server and then set the picture box image property to your bitmap.
Bitmap bmp = new Bitmap("myPath");<br />
pictureBox.Image = bmp;

i m retrieving path from sql
if i write like this
Bitmap bmp = new Bitmap(dr1.GetValue(5));
or this
Bitmap bmp = new Bitmap("dr1.GetValue(5)");

You'll probably have to store the image to HDD, so the picture box can be given a path to display from.

If you're working with Windows forms, why on earth did you ask in the ASP.NET forum ?
Your job is trivial, just read the image data, create a Bitmap in memory, and pass it through to a picture box.

I faced a situation that needs a multiple inheritance. Unfortunately .net is not supporting it. I cannot use an "interface" for this purpose.
Let me tell you the scenario. I have a data layer class say "clsDL". There is another class for the common functions say "clsCommon"(It is common for all modules). I have several modules in my project (several projects in a solution) each module has its own common class for the common functions in that moule. Every form in the GUI layer has a class in Business layer.
The data layer class inherited to "clsCommon" and all the common classes for each module. Now i want to inherite the "clsCommon" and the common class for the particular module into a particular business layer class. I don't want to merge the common functions. If i implement the interface, I have to make an interface for anyone of the two common class and declare the object of that interface class in the business layer class. The problem is that the functions are in these common classes is not same. Therefore, I can't take the advantage of "interface". How can I solve the problem?
P.S: Sorry if I make you confused!

This doesn't make sense, and ties the two layers too closely together.

This sounds convoluted and messy. Why would your data layer and business layer have the same base class ?
The answer is to redesign, this doesn't sound at all right to me.

Yes i think so. I am sad that my all works become useless. I have work again from the scratch. Can you please give me any useful links of articles about this subject?
Thank you

Not off hte top of my head. Just remember, the layers are seperate, they shouldn't have any need for any common base classes, and the business layer should be built around the different business objects, not the different pages.
