Hi,

I have a unmanaged cobol dll compiled in Fujitsu Net Cobol. I have written a proxy wrapper OO cobol class in Microfocus Net Express 5.1 to call that unmanaged dll. There is no compilation error. But during runtime it is throwing an error that unable to load the specific dll.

My question is that is it possible to call a Fujitsu Net Cobol unmanaged dll from Net Express OO cobol wrapper class.

Will be highly obliged for quick reply as I am doing a POC on a trail version.

Thanks in advance.

You state that you created a proxy wrapper OO COBOL class but you do not say whether this is a native Net Express OO class or a managed .NET OO class written in Net Express for .NET..

I know nothing about the format of Fujitsu COBOL .DLLs but if you know what call convention they adhere to (WINAPI, C, etc) then you could probablly call them as you would call any 3rd party program residing in a .DLL.

Take a look at the Net Express help documentation under the section Programming-->Mixed Language programming.

It might be as simple as changing the call-convention used but keep in mind that the Net Express run-time and the Fujitsu run-time systems will know nothing about one another so items like EXTERNAL variables, etc will not work correctly. COBOL data items passed between the two programs may also not be compatible so if you are passing parameters then you should ensure that they are standard strings or integers.

If somebody has experience in working with the two products, please feel free to chime in here.

Thanks.
