Hi there,

first post as ievision user. Using C++ XE4 32 bit and I am not able to run the demo, since the line


OCR->recognize(image, IEVisionRect(0, 0, 0, 0), false, str);

throws an AV.

Read of address 00000000, so it appears that something is not initialized ?
The registered (i.e.: not an evaluation) DLL is in place, same path of executable.

Thanks

/Claudio

Hi Claudio

That is odd. Can you right-click the ievision.dll, select properties and confirm what version it is. Also, what version of ImageEn are you using?

Hi Nigel,

ievision dll is 3.0.8.0 (32 bit)
Imageen was at 7.0.0, so I updated it to 7.0.1, but no way. AV still popping up.

Update:
I am getting AVs only with images that are outside the demo folder. If I copy my images in the demo folder and load from there, all is working.

Sorry for the late reply. In the meantine I upgraded Imageen and Ievision to the latest version.
Problem disappeared.
