ASP to ASP.NET question

[vbMark]

Using previous ASP (not ASP.NET) I was able to pass off functions to COM
objects to do miscellaneous things.

Now, using ASP.NET, I want to pass off some work to a non-web program that
will do some work (access a SQL database, etc) and return the results.

Do I write a COM object in Visual Studio.NET to do this? What template?

Thanks.

NO. Don't write a COM object. Just write a class. You can add the class to
your web project and do whatever you want in it. If you have several
classes which you want to share among web projects, then you can add a new
class library project to your solution and put the classes in there.


A class like this:

MyClass.vb listing


option explicit
Class MyClass

shared function DoSomething() as string
return "Hello"
end function

end class

Would make DoSomething available to all the web pages in your project. Just
call

MyClass.DoSomething()

Will a Class (written in C#) allow me to copy an image from a URL
location to the server's local hard drive if the path is passed from the
ASP.NET page?

Where could I find and example of downloading an image from a URL via C#
code?

Thanks again.

You can do practically anyting in a Class (written in C#).

Where could I find and example of downloading an image from a URL via C#
code?

System.Net.WebClient has a method already coded to do just that.



class util
{
public static void CopyImage(string url, string localPath)
{
System.Net.WebClient wc = new System.Net.WebClient(wc);
wc.DownloadFile(url,localpath);
}
}

Here is what looks like a solution to your problem in vb.net, should be fairly easy to port to C#

Check out the FREE Microsoft .Net SDK:

http://www.microsoft.com/downloads/...A6-3647-4070-9F41-A333C6B9181D&displaylang=en

ASP.Net isn't your dad's tired old scripting ISAPI. It is a fully-compiled
object-oriented programming technology which leverages the full power of the
..Net Common Language Runtime class library. It neither requires nor
interacts well with COM. However, it can do anything you can imagine without
COM, and better than COM.

Download the SDK and start learning what you can do with it!

If the "application" in question is COM, you can include a reference. If
not, you can use the Process class, under System.Diagnostics, to run outside
processes (you can even start the process from this class).

Looking at the rest of the thread, you might not need to do this for what
you are desiring to do, but this is the way you run an outside program.
