Reply To: [Solved] Use EyeX SDK to write visual c++ 2012 windows form programs?

Hi,

Could you please provide the message of the exception?

I can reproduce an exception which states “0xC0020001: The string binding is invalid.” when creating a minimal test using VC++ WinForms. The solution is to call delete on the EyeXHost member when you are closing the program. Here is one small example:

public ref class MyForm : public System::Windows::Forms::Form {
public:
    MyForm(void) {
        // Create EyeXHost
        this->host = gcnew EyeXFramework::EyeXHost();
        this->host->Start();
    }

protected:
    ~MyForm() {
        // Delete EyeXHost to avoid exception
        delete this->host;
    }

private:
    EyeXFramework::EyeXHost^ host;
};

Best regards,
Eddie
