LoadLibrary returns invalid handle 0x10000000

Hi,

I am unable to load my test.dll using LoadLibrary() API. I get error code 126 (Module not found)using GetLastError().
By Dependency Walker, I have come to know that my test.dll depends on "xerces-c_2_7.dll" and "Xalan-C_1_10.dll". These dlls were already present on the same path as the exe.Still I am getting the error.

So I tried to load both the above mentioned third party dlls using LoadLibrary() which returned handle as 0x10000000. By GetLastError() I am getting error code 6 (Invalid Handle).

Can anyone please guide me on why I am getting the Invalid Handle error?

HINSTANCE hLib = LoadLibrary(_T("Xalan-C_1_10"));
	TCHAR szMessage[MAX_PATH];
	FormatMessage(FORMAT_MESSAGE_IGNORE_INSERTS|
		FORMAT_MESSAGE_FROM_SYSTEM,
		NULL, GetLastError(),
		MAKELANGID(LANG_NEUTRAL, SUBLANG_NEUTRAL),
		szMessage, MAX_PATH, NULL);
		hLib = LoadLibrary(_T("xerces-c_2_7"));
	FormatMessage(FORMAT_MESSAGE_IGNORE_INSERTS|
		FORMAT_MESSAGE_FROM_SYSTEM,
		NULL, GetLastError(),
		MAKELANGID(LANG_NEUTRAL, SUBLANG_NEUTRAL),
		szMessage, MAX_PATH, NULL);

Have you tried this:
HINSTANCE hLib = LoadLibrary(_T("test.dll"));

I noticed that the file extension is missing in your sample code.

Yes. It is not making any difference.

Are you sure the module is in the LoadLibrary search path?

That's fine.

Why did you call GetLastError while LoadLibrary didn't fail?

Just as a silly check, try to put test.dll file into the system directory (for instance: C:\Windows\System32).

Then I would drop any dependance (i.e. make a stub of 'test.dll', an almost-empty DLL just for testing purposes) and then try to load it.
You should stay simple when debugging.

Thanks all for replying. I could able to solve the issue. The problem was not with those two third party dlls. test.dll requires some MFC & Visual Studio specific dlls (mfc90d.dll, msvcp71d.dll, msvcp90d.dll, msvcr90.dll, msvcr90d.dll, msvcr71d.dll).

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
