Question

am using bitblt API to capture window screen it taking approximately 30 to 40 Milliseconds but i want to make this in more faster way so is any other inbuilt API or suggest me best screen capture drivers.

Here is my code.

ret = BitBlt(m_pGDI->hDoubleBufferWorker,0,0,this->m_screenWidth,
            this->m_screenHeight,hDisplayDC,this->m_scrennOffsetX,this->m_scrennOffsetY,SRCCOPY|CAPTUREBLT);        
        if(!ret)
        {
            int err=    GetLastError();
            ErrorLogger::Log("Error : Desktop : Bitblt failed%d",err);      
        }
