Hi,
I have a registred ocx that implements the fallow method
CString COPOSCashDrawer::GetDeviceDescription()
{
CString result;
InvokeHelper(0x1d, DISPATCH_PROPERTYGET, VT_BSTR, (void*)&result, NULL);
return result;
}
I created a dll that implements the fallow method:
STDMETHODIMP CCashDrawer::get_DeviceDescription(BSTR *pVal)
{
AFX_MANAGE_STATE(AfxGetStaticModuleState())
CComBSTR bstStr( this->DeviceDescription );
*pVal=bstStr.Detach();
// TODO: Add your implementation code here
return S_OK;
}
This method belongs interface ICashDrawer : IDispatch
I want to do a application that make the ocx's method
CString COPOSCashDrawer::GetDeviceDescription() make call to the dll's method
STDMETHODIMP CCashDrawer::get_DeviceDescription(BSTR *pVal)
I tryed to import the Controll into a project(Project->Add to
Project->Componentes and Controls->Registred ActiveX Controls), then I tryed
to create a instance of a ocx's class and make call to the method
GetDeviceDescription(). The fallow error menssage was draw me:
DEBUG ASSERTION ERROR!
File: Winocc.cpp
Line: 345
Please, can you help me?
Grateful!
