#import [dllname] no_namespace

or

prefix the SimplePgpPtr with the namespace declaration. Look at the generated [dllname].tlh and [dllname].tli to find out what the name of the namespace is. It would be same as the typelib name you gave to your COM server.

I did that and found that this now compiles :-

CoInitialize(NULL);
ISimplePgpPtr p(__uuidof(ISimplePgp)); <-- Run Time ERROR
//p->EncryptFile("d:\\in.txt","d:\a90.pgp","test@test.com");
CoUninitialize();

But program crashes at the above show line Cry | :((

It refuses to compile

error C2059: syntax error : '__uuidof'

Hello Nish,

Are you compiling it as a c++ file ? __uuidof() is both Microsoft & C++ specific so if it's in a .c file you might get this error. Also why are you using SimplePgp instead of _SimplePgpPtr (that's the generated smart pointer) and write _SimplePgpPtr p(__uuidof(SimplePgp).

you will still have to call the properties with -> but you can also access the smartpointers own methods trough the . operator.

Hope this works. the __uuidof turns blue in my vc 6.0 env so it's a recognised keyword.

Regards

Rutger

It's a CPP file.

I am now getting this error

error C2065: '_SimplePgpPtr' : undeclared identifier

Writing test's in VB is far more easier than writing in C++. So continue using VB. Smile | :)

Try this one Nish:

CoInitialize(NULL);
{
    IYourInterfacePtr pServer;

    HRESULT hr = pServer.CreateInstance(__uuidof(YourInterface));

    if(SUCCEEDED(hr))
    {
        ..........
    }
}
::CoUninitialize();

Also add #include "YourInterface.h" and #include "YourInterface_i.c" to your file.

Hope that helps.

Mazy, thinmgs just got even more strange.

I tried out Jason's suggestion and instead of __uuidof(..) I did this :-

HRESULT hr=p.CreateInstance("TestCom.SimplePgp");

And it works fine!!!

Now I gotta figure out why __uuidof() failed both at office and here at home Confused | :confused:

    std::cout << hr << "\r\n";

On running this I get this as the HRESULT error :-

I am sure the class is registered Cry | :((

Make sure its registered by running Regsvr32.exe "yourdll".
Also, try using the version independent progid instead of __uuidof(ISimplePgp). You can get this from the registry or you can usually find it in the OleCom Object viewer.
