    ---Mình dùng thử soft bạn viết và đụng lỗi "Attempted to read or write protected memory". Mình có thấy vài bài bạn viết nói rằng là do ảnh ko chụp tốt. Google thêm trên mạng thì đây là lỗi liên quan đến managed/unmanaged code, và .NET Framework 2.0 rất hay bị lỗi khó chịu này. ---Trên mạng người ta suggest là nâng lên tối thiểu 4.0. Bạn có thể sửa lại source code mà chỉnh target framework lên cao được không ? Do code bạn bị dependency nhiều dll quá nên mình không rành mà chỉnh tay được. ---Hơn thế nữa, nếu bạn không phiền thì bạn có thể đóng gói lại thành 1 thư viện dll để người khác dễ tích hợp lại vô app được ko ? Như cách bạn đã add reference dll của bọn nước ngoài ấy, bọn nó làm rất gọn nhẹ và không cồng kềnh vụ giao diện. Việc này giúp người khác tập trung quan sát thuật giải và tích hợp vô app dễ dàng thôi. ---Cám ơn bạn nhiều.

    I am searching for it since a long time.But i didnt get any best solution for me. But recently i got a solution what i really need. That is VietOCR.Its a open source project.So I love it a lot. But i have also a big problem with it. That is when i tried to load the project with my visual studio 2010 (GUI.CS) it shows a message like this : To prevent possible data loss before loading the designer, the following errors must be resolved: The designer could not be shown for this file because none of the classes within it can be designed. The designer inspected the following classes in the file: GUI --- The base class 'VietOCR.NET.GUIWithRegistry' could not be loaded. Ensure the assembly has been referenced and that all projects have been built. I also tried old version too but problem is same. Can anyone pls tell me how to solve this problem ? I need this very very very much. Thanks in advanced.
