That's only possible if the dll is a registered COM server. For more info see this thread: http://p2p.wrox.com/topic.asp?TOPIC_ID=18052 and msdn.microsoft.com

No, since as said it in the other forum, that would be a huge security hole. It would even be possible to run any and all programs on someone else's computer without his knowledge.

I have done the following steps in .net visual studio 2005 IDE to register my .net dll as COM.
1)Project->Project property>build>and checking "Register for com interop" box
2)even use regasm and regsvr32 and tried to register.but cud not register

Have you defined and implemented the interfaces correctly? I know very little about COM or .NET, but I do know that it often requires a rewrite of the type definitions to add the COM-interfaces instead of the exported functions. Perhaps people in the C#-board can help you better.

No probs.I got the solution.

Hi,

I have exactly the same problem.

I wrote a Com Assembly with C#, registered it with regasm and pushed it into the gac with gacutil successful.
So far so good.

Now I have to use it in Javascript
I tried it like this:
function lib ()
{
alert("here i am");
try
{
var test = MyLib.Class1.info(); //Namespace.Class.Function
alert ("Test: "+test);
}
catch (e)
{
alert("exc "+e.message);
}

}
e. message is: MyLib is undefined
What did I wrong?
Can you help me please? Or show me your solution?
thx!

Dear friend,

i encounter same problem.
so i have created a .NET DLL Class Library.
But i don't know how to call and use this DLL method, event in JavaScript ?
Could you help ?

2.
other solution is we have to re-build the DLL using VB 6.0 , but it's funny since we're already using VB .NET.

Tks,
hendy

Friend, i have a great solution of this problem, use AJAX.NET library, don't worry, this library is very simple to use, this library has the ability to use ServerSide functions (C#,VB.NET) function using JAVASCRIPT.
download this library and enjoy it, i hope this will be very useful to u.

Hi.

Does it work for you (using C# dll by javascript)?
Still fighting with this...

Thanks.

you can do this by using AJAX technology. but the C# code will get executed at the server side only

We can dll C# function as follows

Add Dll referrence to your application and in design page add following code

e.g . consider GetDate.dll having "Date" as a class
<script language="javascript" type="text/javascript" >
<%
//Creating object for Date class
Getdate.Date dt=new Getdate.Date();

%>

// Calling C# function from Dll
var date='<%=dt.GetDate() %>'
alert(date)
</script>
