General Protection Fault in the engine

Hi

I am using LeadTools 14.5 Evaluation version.

My program would call a method to recognize the wording of a image when I click a button.

The method runs successfully.

However, after I recognize several image, it crashes with the error "General Protection Fault in the engine"

I use an error handler to catch this exception and then I recall the function.

I runs successfully again. However, after recognizing several images, again, it crashes.

Here is my code segment and the program always crashes in the statement:

result = _rasterOcr.SaveResultsToMemory();

public string Recognition()

string currentPath = Application.StartupPath;

string result = string.Empty;

if (File.Exists(currentPath + "\\nec.rdf"))

try

catch (RasterOcrException ex)

result = string.Empty;

return result;

Thank so much  ~

Hi

I have uninstall, reboot and then reinstall the Leadtools SDK but the problem cannot be solved.

Here is one of the sample image file which causes the problem, but the problem not always happens. It only occurs after several recognizations, and I found that, the problem not occurs randomly (as I get the same error pattern for the same image).

Thank you for your kind concern.

Hi,

Thank you for your reply.

After I compared the code with yours and mine, I find that the different is like that:

<Yours>

for (int i = 0; i < 20; i++)

{

ocr.Startup( );

//recognization process

ocr.Shutdown( );

}

<Mine>

ocr.Startup( );

for (int i = 0; i < 20; i++)

{

//recognization process

}

ocr.Shutdown( );

After I changed my code as yours, it works fine~~~(although it is a bit slower [:P]).

 Thanks alot~ [Y]
