Syntax Error

[tramimaus]

Hi!

Can somebody help me out?
I get a syntax error, when I try to compile this code.
The syntax error indicates,that I'm missing something before the else if(riid==IID_IX).

Can somebody help me out? Thanks!

if (riid == IID_IUnknown)

*ppvObject = static_cast<IUnknown*>
else if(riid == IID_IX)
*ppvObject = static_cast<IX*>(this);
else if(riid == IID_IY)
*ppvObject = static_cast<IY*>(this);

else
{
ppvObject = NULL;
hr = E_NOINTERFACE;
}

Add semicolon to terminate an assignment...

*ppvObject = static_cast<IUnknown*>

That is not a complete static_cast. You forgot the (this); at the end.

Thanks!

I inserted the (this); but now I get another error: 'static_cast':ambiguos conversion

if (riid == IID_IUnknown)

*ppvObject = static_cast<IUnknown*>(this);
else if(riid == IID_IX)
*ppvObject = static_cast<IX*>(this);
else if(riid == IID_IY)
*ppvObject = static_cast<IY*>(this);

any ideas?

What type of object is 'ppvObject' and what type of object is 'this'? You can't cast them unless they are similar types (i.e. inherited). You could try changing the static_cast to a dynamic_cast or as a last resort reinterpret_cast.
