No problem Mike.

OnProgress is used to show a progress bar of what is happening. Below you will find the code. When the ocr is working on the graphic, it will call the function that I passed it to update progress within my application.

Hope that helps
Mike Crapo

//In header file
void __fastcall OnProgress(const TObject *Sender, const unsigned char PercentProgress);

//In cpp file
void __fastcall TfrmDocImage::OnProgress(const TObject *Sender, const unsigned char PercentProgress)
if(PercentProgress < 100)
ProgressBar->Position = PercentProgress;
ProgressBar->Visible = true;
ProgressBar->Visible = false;
