When I look at the online help it states that there is a return value.

But when I import the core api dll in visual studio c# it says its a void function???

[DispId(1610743904)]
void DeferedDigitalSign(ref _CERT_CONTEXT pCert, uint nFlags, uint nPageIdx, ref PXC_Rect pRect, string sReason, string sLocation, string sContactInfo, string sImageFile);

So how do i know if the procedure was successful?

Hello Tom,

That's the C# wrapper. The C++ uses HRESULT to return the value. In the C# you will need to use the try-catch block to handle exceptions.

Cheers,
Alex

And is there a way to catch the error code?

Of course - read the try-catch explanation on the msdn:
