The attached VB.NET example will allow you to load an image and perform OCR on it. You can then specify a word you wish to search for within the image. If the word is found, a highlight annotation will be displayed over the word.

Hi:
Is there a VC++ version of this code? Any pointers would be useful. Thanks. Anand

Hello,
Unfortunately, we don't have one available in VC++, but the code flow is the same. You just have to use the corresponding functions available in the API library. Our C++ Class Library is very close to this. If you have anything specific that you have trouble with we can help you out with that.
Thank You

Thanks, I could figure it out. But when I output the recognized word to a file, it prints out hex (even if I use the %s qualifier). Am i missing anything obvious? Thanks

Hello,
Can you post the code snippet which gets a word from the recognized page and prints it to the console/file. I'm thinking it's because it might be returning in Unicode char set, but I'm not 100% sure on it.

yes it is returning the unicode charset. I tried:
myfile << pRecogWords[i].szWord; // (prints unicode)
myfile << printf("%s",pRecogWords[i].szWord); // (prints a single digit)
and similar combinations.
Thanks

Yes, the szWord is of type L_WCHAR which is the same as WCHAR. If you want to conver it to a LPCSTR you can use the WideCharToMultiByte() function in windows.h. Documentation for it is here: http://msdn2.microsoft.com/en-us/library/ms776420.aspx
