Creating an Instance using precreated Web Service
I am trying to write a program that uses a Web Service in C++, VS 2005.
It fails because COM is not initialized.
When I try to initialize COM in the usual way by making a COM class
and then calling Initialize it fails to link saying CoInitialize is unresolved.
Is there a library I should link in?
class
CCom
{
private :
HRESULT m_hr;public
:
CCom() : m_hr(E_FAIL)
{
} HRESULT Initialize()
{
ATLASSERT(FAILED(m_hr));
return m_hr = CoInitialize(NULL);
} ~CCom()
{
if (SUCCEEDED(m_hr))
CoUninitialize();
}};
// then later
CCom COM;
HRESULT hr = COM.Initialize();
So how do you get COM going in C++ VS8 for a Smart Device?

Hi -
Was hoping for a little more help.
Now that I have COM initialized I was trying to do CreateInstance for the Web Service using the information in created when you add a Web Reference to your solution.
It gets setup automatically with C# or VB.
Maybe using the Web Reference is not the way to go here.
Maybe for C++ it all needs to be done by hand.
Anyway below is the header file created by the 'Add Web Reference' wizzard.
