SetLicenseNumberOCRTesseract

[ronk]

I have an old Visual Foxpro application that my client wants to upgrade to .net version from GdPicture Toolkit Pro version 5. I have previously received some help and know that I need to do the folllowing to use the .net version :

oGdPictureImaging = CREATEOBJECT("GdPicture9.GdPictureImaging")
oGdPictureViewer = CREATEOBJECT("GdPicture9.GdViewer")
thisform.GdViewer1.SetLicenseNumber("30 day evaluation license")

This works fine and I have benn able to use this line to extract text from pdf documents:

vtextbit=thisform.GdViewer1.PdfGetPageText()

However, the program needs to use OCRTesseract and I am having 2 issues (I am using the latest demo version, downloaded yesterday)

The program previously had:

thisform.olecontrol2.SetLicenseNumberOCRTesseract("xxxxxxxxxxxxxxxxxx")

I have attepted to use the following without sucecss:

oGdPictureImaging.SetLicenseNumberOCRTesseract("30 day evaluation license") - it doesn't recognise the name

The scaning previously said:
thisform.olecontrol2.SetNativeImage(thisform.olecontrol1.GetNativeImag
thisform.olecontrol2.ResetROI
vtextbit = thisform.olecontrol2.OCRTesseractDoOCR(2, lcOcrDir)

and I have changed this to:

vtextbit = oGdPictureImaging.OCRTesseractDoOCR(vimage, "eng", lcOcrDir, "") where vimage is the document name and lcOcrDir is a valid path to the dictionary files.

Could you please give me some advise as my client is anxious to upgrade and I am a bit lost. Thank you in advance.

Hi.

You need to use the RegisterKEY function of the LicenseManager class instead. Here are links to show you how to do it:

Thank you for your prompt reply. Unfortunately I have zero experience outside Visual Foxpro in any of the supported languages and am not always sure how to convert them.

Do you mean (in Visual Foxpro):

LicMgr = CreateObject("GdPicture9.LicenseManager")
LicMgr.RegisterKEY(MY_PLUGIN_KEY) && with MY_PLUGIN_KEY being the demo key supplied for the 30 day trial
The above runs successfully in the command box of Foxpro.

If that is correct, is my programming re the line:
vtextbit = oGdPictureImaging.OCRTesseractDoOCR(vimage, "eng", lcOcrDir, "") correct?

Running the above line in the command box gives me the message ""OLE error code 0x80004002: No such interface supported."". I am running Visual Foxpro 9.2.

Thank you for your patience.

Sorry for the last post - I realise I was using an invalid value for vimage so please ignore that part. I still have an issue but wiil post in the code snippet area.

Thanks.
