    'Set up the image you want to process.
 
    'Run the OCR process.
    Dim resID As String = gdpictureOCR.RunOCR()
    If gdpictureOCR.GetStat() = GdPictureStatus.OK Then
        'Check the results.
        Dim wordCount As Integer = gdpictureOCR.GetWordCount(resID)
        'Continue ...
    Else
        MessageBox.Show("The OCR process has failed with the status: " + gdpictureOCR.GetStat().ToString(), caption)
    End If
 
    'Continue ...
End Using

string caption = "Example: GdPictureOCR class";
using (GdPictureOCR gdpictureOCR = new GdPictureOCR())
{
    //Set up your prefered parameters for OCR.

    gdpictureOCR.AddLanguage(OCRLanguage.English);
 
    //Set up the image you want to process.
 
    //Run the OCR process.
    string resID = gdpictureOCR.RunOCR();
    if (gdpictureOCR.GetStat() == GdPictureStatus.OK)
    {
        //Check the results.
        int wordCount = gdpictureOCR.GetWordCount(resID);
        //Continue ...
    }
    else
    {
        MessageBox.Show("The OCR process has failed with the status: " + gdpictureOCR.GetStat().ToString(), caption);
