hey

i would like to ask how do we add a C++ dll to asp.net?

I kept getting errors when adding it.

Error shown:

 A reference to 'C:\Documents and Settings\username\MyDocument\Futronic

dll\FASExtend_DLL_v1.3\dll\FasExtend.dll' could not be addded.No type libraries were found in the component.

Hi!

Look this page, may be useful.

please add this dll file as web reference to the application and add ' using ' statement in every page where you are going to use this file and its functionality. Rebuild the application.

Hi .,,

follow the below steps :

 1) Register the C++ dll library using the   regsvr32.exe "absolute path of that dll "  from the command prompt.

2)  use the namespace " system.runtime.interop" in your .cs file

3) Now  Add the dll using the "Add Reffrence" option in your development studio..

Hope it helps... :)

 i think you must import it by command prompt and type

regsvr32  FasExtend.dll

or if he can't register it so you can't add this dll

Thanks for all the suggestions given.But iwhen i type at command prompt regsvr32 FasExtend

an error pop up:

LoadLibrary("FasExtend.dll") failed - The specified module cannot be found.

 May be the file is not there. Or you have given an incorrect path.

Hi,

Please try to refer to ReiterIstvan's post.

I hope this helps.

Hi..,

you need to give the complete path(Physical location of that dll path followed by the dll name)

hey

so you mean i need to declare the directory of my dll is it?

Yes.., you need to give your directory path of the dll contained and append it with your dll name

Hi ccc,

Please read the following article:
http://blog.rednael.com/2008/08/29/MarshallingUsingNativeDLLsInNET.aspx

It's an in-depth article about how to use a native DLL (or C++ DLL) in your managed .Net code. The article shows which types are interoperable, how to import a DLL, how to pass strings, how to pass structures and how to de-reference pointers.

And C# source code examples are included.
