Description

做定值组控制的时候,脚本里面执行Pause(3000)的动作,此时频繁的在图片上点击图元,程序会闪退.

pause函数允许程序继续响应 MOUSEMOVE， 相应的处理函数会影响到正在执行的脚本线程，尤其是GWnd::m_shapeid，造成后续的指针转换时错误。

修改： 调用Pause时，程序对 MOUSEMOVE的响应处理进行屏蔽

脚本执行Pause的时候,会PeekMessage,但是WM_MOUSEMOVE并没有被拦截,
在Pause执行过程中,如果移动鼠标,会频繁的调到GWnd里面PointSelect函数.
脚本执行是个耗时操作,执行的代码在
if (g_ehmiMainFrame->m_bScript && pObj->GetScriptLen() > 0 && pObj->GetStyle() & OS_ENABLED) {
if (flag == lbtn_up) {
if (RBAC_CheckPrivilege(DEF_RIGHT_OPERATOR)) {
BeginWaitCursor(); // display the hourglass cursor

m_pCurObj = pObj;
                    if (m_shapeid == OS_BUTTON)
                    {
                        if (pObj->IsObjectMouseIn())
                        {
                            m_pView->m_Script.ExecString((const char *)pObj->m_pScriptData, this);
                        }
                    }
                    else
                    {
                        m_pView->m_Script.ExecString((const char *)pObj->m_pScriptData, this);
                    }
                    m_pCurObj = NULL;
EndWaitCursor();    // remove the hourglass cursor
                }
                m_runScript = TRUE;
            }
            else if (flag == mouse_move)
                m_runScript = TRUE;
        }

等这个脚本执行完毕,m_shapeid所指向的内存已经变了, 后续在做
CPointDevice *pdev = (CPointDevice *)pObj;
m_pObjSelect = pdev;
pdev->GetDevInfo(m_seldev);
的时候,就会出错0x0000005错误.
程序闪退.
