If hLib is not NULL, then LoadLibrary() is not failing.

Is it possible that your app is a 64 bit application and your dll an 32 bit dll?

you should load the dll from the directory where it was installed, so the dll can find the depending modules. Sigh | :sigh:

_Connection as parameter in IDL file

Hi,

I need to know how can i pass the type _Connection (or _ConnectionPtr) as parameter in function in the IDL file ?

This is some lines of code :

Test.cpp

_Connection *pConn = NULL;
IDataExtract->get_ADOConnectionObject(&pConn);

IDL file
[id(38), helpstring("get connection")] HRESULT get_ADOConnectionObject([in, out] ???????????????);

thank you for help.

If you import ADO into your IDL file (try using importlib with the ADO type-library), then you can use _Connection*, i.e. an interface pointer.

i have include ADO type-library like this:
importlib("C:\Program Files\Fichiers communs\System\ado\msado15.dll");
in the Library section

and i had wrote :
[id(38), helpstring("get connection")] HRESULT get_ADOConnectionObject([in, out] _Connection** pConnptr);

but it display error :
Error 1 error MIDL2009 : undefined symbol : _Connection [ Parameter 'ppAdoConnection' of Procedure 'get_ADOConnectionObject' ]

So how can resolve this problem ?

thank you

This works for me:

import "oaidl.idl";
import "ocidl.idl";

[
	uuid(D39DD965-FC96-4C0A-AA62-CA3F5F117685),
	version(1.0),
	helpstring("cccc 1.0 Type Library")
]
library ccccLib
{
importlib("c:\Program Files\Common Files\System\ado\msado15.dll");
   [
	   object,
	   uuid(7CD26371-4A6B-4234-A024-6690A53CA450),
	   nonextensible,
	   helpstring("Itest Interface"),
	   pointer_default(unique)
   ]
   interface Itest : IUnknown
   {
      HRESULT DoSomething([in]_Connection* c);
      HRESULT GetCount([in]_Recordset* rs, [out]int* num);
   };
	importlib("stdole2.tlb");
	[
		uuid(F8AAE058-76E9-4F2C-995A-FB5B6565CED6),
		helpstring("test Class")
	]
	coclass test
	{
		[default] interface Itest;
	};
};

Alternatively, remove the importlib statement and add

import "MSADO15.idl";

either in or out of the library's scope. Both of these have worked for me

Spotted it. You define _ISAC_Session OUTSIDE the library, so it cannot see the ADO definitions brought in by the importlib statement, as that is wihtin the library definition.

Changing the importlib to an import statement OUTSIDE the library definition will fix your error. Here's the sample code you posted, modified so it'll work. I've highlighted the import statement I added.

#pragma once
import "oaidl.idl";
import "ocidl.idl";
<big>import "msado15.idl";</big>
