When you declare an object "static", will it be shared among different users of different machines? I couldn't test it cuz I'm testing from a single machine. I put a static variable in a common code and every time I visit a page, it shows the (user-specific) static data no matter how many refresh you make. that's fine. But will the same data be shown to any other users accessing the same page? "Static" has that much of scope??.
Thanks for your reply.

Yes, that is what static means. You have one server, one application instance, and static variables will be shared across it.

Where is the data coming from? Is this using a data bound control ? If you're just building a table, why do you need a server control ?

myarray(i)=1
Next
for d as integer =0 to 31
dim tc as tablcell = new tablecell
if testarray(d)=1
tc.backcolor= color.green
else
tc.backclor= color.yellow

hi,
i have a grat problem, when i print on crustal repport, the page will be refrech, there are a methode for stoping this refrech?? thank you very mutch.

I assume that the print operation includes a postback to get data. If it's refreshing, it's because it needs to.

By a book on ASP.NET so you can understand what it is, and how it works.
Why would it do a refresh, if it didn't need to ?

What kind of system are you using? That would work on a *nix system, as that uses "/" as file path separator, but it would not work on a Windows system, as that uses "\" as file path separator.
You should use the Path.Combine method to form the path, that way it will work regardlesss of what file path separator the system uses:
Path.Combine(Server.MapPath("~/temp"), SID)
Despite everything, the person most likely to be fooling you next is yourself.

i checked
Server.MapPath("~/temp") +"/"+ SID . it works .
just when i use
Directory.Delete or
Directory.CreateDirectory it takes Error.
i set the permission also!
How could I solve it?

In what sense do you mean that it works?
If you are using it as a path in a Windows system, it's not correct. It might work eventhough in some situations, but fail in others.

Eh? I already told you. Gave you the code for it and everything.

Did you consider using the debugger to see what the path is it's trying to write to ?

I cant use it! because it happen when i upload it not at localhost 
|

Then write a page which works out the path and writes it to the page, so you can see what you're dealing with.

You had better debug it,or create a new file to debug filepath validation.Certainly,you also use following:
Directory.Delete(Server.MapPath(@"./temp")+"//"+sid,true);
or
Directory.Delete(Server.MapPath(".//temp")+"//"+sid,true);
Ple notice "/" in limit!

Set it as a hiddenfield server control.

string s1=(string)ViewState["s"];
