调用SendMessage

Question

我使用WatIn并使用saveAs对话框保存文件，但是当我锁定windows / pc时，此过程停止，我需要将Invoke转换为SendMessage，当我的电脑锁定时，此过程仍会运行。

有办法做到这一点吗？

使用Invoke

的代码

  private static void ClickSaveAs(AutomationElement mainWindow, AutomationElementCollection dialogElements, string filename)
        {


            foreach (AutomationElement element in dialogElements)
            {

                if (element.Current.Name.Equals("Save"))
                {
                    AutomationElementCollection dialogSubElements = element.FindAll(TreeScope.Children, Automation.ContentViewCondition);
                    InvokePattern clickPatternForSaveDropdown = (InvokePattern)dialogSubElements[0].GetCurrentPattern(AutomationPattern.LookupById(10000));
                //I need to change this to..
                   clickPatternForSaveDropdown.Invoke();

//This
                    //start
                    int intWhdr = FindWindow("IEFrame", "");
                    int currChild = FindWindowEx(intWhdr, 0, "", "Frame Notification Bar");
                    currChild = 104755016;
                    int intRes1 = SendMessage(currChild, WM_LBUTTONDOWN, 0, 0);
                    System.Threading.Thread.Sleep(100);
                    intRes1 = SendMessage(currChild, WM_LBUTTONUP, 0, 1);
                    System.Threading.Thread.Sleep(200);
                    //end
                    Thread.Sleep(1500);

                    AutomationElementCollection dialogElementsInMainWindow = mainWindow.FindAll(TreeScope.Children, Condition.TrueCondition);
                    foreach (AutomationElement currentMainWindowDialogElement in dialogElementsInMainWindow)
                    {
                        if (currentMainWindowDialogElement.Current.LocalizedControlType == "menu")
                        {
                            // first array element 'Save', second array element 'Save as', third second array element    'Save and open'
                            InvokePattern clickMenu = (InvokePattern)currentMainWindowDialogElement.FindAll(TreeScope.Children, Condition.TrueCondition)[1].GetCurrentPattern(AutomationPattern.LookupById(10000));
                            clickMenu.Invoke();
                            Thread.Sleep(1);
                            ControlSaveDialog(mainWindow, filename);
                            break;
                            //strt


                            //end
                        }
                    }
                }
            }
        }

当机器锁定时，Watin将无法工作。由于它使用了Microsoft.mshtml和Interop.SHDocVw二进制引用。这些二进制文件是COM组件，需要交互式UI。对于示例，您可以尝试登录而不是下载。开始测试并锁定机器然后解锁。观察结果，它将失败抛出像COM异常的错误....尝试使用Reg键更新永久解锁机器作为选项......
