Subject: Testing Envision Image Library C Builder

I am testing your Library with C++ Builder 5 Pro. I am trying to create a C++ Builder App to test with based on your Delphi/Pas Demo. Do you have the same code in C++?
Here is a sample of my code and the current error I am getting.

In Header file:

private: // User declarations
void __fastcall OnAcquire( const THandle DibHandle, const unsigned short XDpi,
const unsigned short YDpi, const int CallBackData);
typedef struct TpScanInfo
{
bool MultiPage;
const TTiffGraphic* Graphic;
TFileStream *ScanStream;
long int ImageCount;
} TScanInfo;

In CPP Unit:

void __fastcall TForm1::OnAcquire( const THandle DibHandle, const unsigned short XDpi,
const unsigned short YDpi, const int CallBackData)
{

TScanInfo *pScanInfo = new TScanInfo;
pScanInfo = TpScanInfo(CallBackData);

Here is where the error is generated:

[C++ Error] MainUnit.cpp(77): E2031 Cannot cast from 'const int' to 'TForm1::TpScanInfo'

Thanks,

Don
