Hi All, I found out the solution for error C2504: 'AnyObject' : base class undefined My tlb is dependent on some other tlb so, what i did is I #import the base tlb before importing my tlb. It complies fine. There are no errors. But, I am not able to get pointer to my COM object, when I am running following sample code CoInitialize(NULL); IMyComObject pObject(_uuidof(MyComObjectName)); I am getting following error in CoCreateInstance method 0x80040154 Class Not Registered I checked the registry, there is an entry for my typelib. I am not sure why it is not able find the class. Any suggestions/help please.. Thanks in advance JK

Hi Arman, Thanks for the sample code I did import my tlb file with rename_namespace("MYNAMESPACE") option I got following two compilation errors 1) error C2664: '_com_issue_errorex' : cannot convert parameter 2 from MYNAMESPACE::MYCLASS *const ' to 'IUnknown *' 2) error C2504: 'AnyObject' : base class undefined I tried import using following command #import "C:\temp\Mytlb.tlb" rename_namespace("MYNAMESPACE") raw_interface_only The first compliation error went off but the second error error C2504: 'AnyObject' : base class undefined still exists. When I see my tlh file my class is deriving from AnyObject base class. I am not sure why it is deriving from AnyObject? Is there any base class called "AnyObject" in C++? If yes what are the include files i need to include? Please help me. Thanks in advance. Regards JK

Hi Arman and Mark, Thanks a lot. Its working fine with wstring for me.There are no compilation errors now. But I am having one more problem. I am using text resource file in my VC++ workspace. I have included *.rc and *.h file. but I am not able to get the handle to resource file. Following is the sample code. TCHAR sResName[5] = _T("#103"); TCHAR sRestype[12] = _T("MY_RESOURCE"); HRSRC hres = FindResource(NULL, sResName, sRestype); HGLOBAL hbytes = LoadResource(NULL, hres); LPVOID pdata = LockResource(hbytes); LPBYTE sData = (LPBYTE)pdata; LPTSTR sXml = (LPTSTR)sData; wstring strXml(sXml); In the above code i am not getting hres pointer. The address of hres is null. Do u have any idea why I am not getting the pointer to resource file using FindResource(). I have included the resource file in the header files folder. Is there any better way of doing the same? Thanks in advance JK
