Hi Ron,

I have a small example with uses Acquire (not AcquireWithSourceOpen) but the signature is the same.

Below you will see a snippet of the code. If you want, give me you email address and I can send you the entire project.

Best regards,

Michel

void __fastcall TMainForm::FormCreate(TObject *Sender)
{
FScanner = new TScanner();
}
//---------------------------------------------------------------------------
void __fastcall TMainForm::FormDestroy(TObject *Sender)
{
delete FScanner;
}
//---------------------------------------------------------------------------
void __fastcall TMainForm::ScanBtnClick(TObject *Sender)
{
FScanner->Acquire( ImageAcquired, 0 );
}
//---------------------------------------------------------------------------
void __fastcall TMainForm::ImageAcquired(
const unsigned DibHandle,
const Word XDpi,
const Word YDpi,
const int CallBackData)
{
ImageScrollBox->Graphic->AssignFromDIBHandle(DibHandle);
ImageScrollBox->Redraw(True);
}
