Hi,

I've just started to peek into the .NET world generally and C# in

particular. My first obstacle is that I can't find a way of using an

existing COM component. In VBScript, i used something like



	dim cObj

	set cObj = Server.CreateObject("MyProj.MyObj.1")



How do I do the same thing in C#?



(MyProj.MyObj is made in C++)



Regards, Lars

Are you using Visual Studio.NET Beta 1 ?



If so you can simple add a reference to you COM component.

We say that you want to use the old ADO.



First you right click on the reference node in the Solution explorer.

Choose to add a reference, after that select COM and choose Microsoft

ActiveX Data Object 2.x.



Now you can simply write:



using ADODB;



....



Connection myCOnnection = new Connection();



Most COM components will continue to work under ASP.NET. You can still

implement late binding using Server.CreateObject as with previous versions

of ASP

Thanks Fredrik, it worked!

But..

I used the PDC version on an w2k Advanced Server and added a 'using

MYCOMPLib;' to my ASP+ WEB Application (C#), accessed my component and 

had a

good life. Then I installed a new VS.NET (beta 1 from MSDN website) on 

a w2k

Professional and tried the same thing. When I try to add the 'using

MYCOMPLib;' I get a "The type or namespace name 'MYCOMPLib' does not 

exist

in the class or namespace 'MyWorkspace'"

I still use my old asp pages and access my component on the same 

computer,

so I know the component is registered and fit for fight.

What am I missing? Please help!



Thanks, Lars

COM components are not directly compatible with .Net framework,

(i dont know if .Net components are compatible with com however)

u have to convert a component into a .Net type of dll using tlbimp

how to use it?

-- goto command prompt

   tlbimp <Filename/path>

it will create a dll in the current directory,

note this dll cannot be registered.

copy this dll into the 

<SystemDrive>:\WINNT\Microsoft.Net\Framework\<***

whateever beta version - here v1.0.2204>

or copy it into the application directory wher u want to use the dll & 

then

u will be able to use the current components.

u cannot use the current components directly, unless u use

server.createobject (in vb) to instantiate it explicitly

for more info read .Net framework documents & help on using com 

components
