CoddedUI抛出异常 - 无法找到底层进程的主窗口 [英] CoddedUI throwing Exception - Unable to find the main window of the underlying process

问题描述

您好， 

我正在尝试使用以下代码启动Winform应用程序： 

1 -

  ProcessStartInfo p = new ProcessStartInfo（@"filepath\Domino.Winview.exe"）;

            p.WorkingDirectory = Path.GetDirectoryName（@"filepath\Domino.Winview.exe"）;

            Process AppProcess = Process.Start（p）;

            ApplicationUnderTest appStartApplication = ApplicationUnderTest.FromProcess（AppProcess）; 

2- 

ApplicationUnderTest calcApp = ApplicationUnderTest.Launch（@" filepath \ Domino.Winview.exe"）;

在两种情况下启动应用程序但抛出异常： 

无法找到基础流程的主窗口

解决方案

您好Kapil_dell，

欢迎来到MSDN论坛。

经过实验，他们可以在我这边正常工作。我的运行环境：VS2017 enterprise，win10。

您可以使用process.start（路径）和ApplicationUnderTest.Launch（Path）来尝试启动应用程序。而且他们两个也可以成功地在我身边。

如果问题仍然存在，您是否可以分享有关该项目的更多详细信息，或者我希望您可以使用github或一个驱动器共享示例，然后我将下载并测试我的。$

期待您的回复。

最好的问候，

迪伦

Hello, 

I am trying to launch a Winform application using below code: 

1-

 ProcessStartInfo p = new ProcessStartInfo(@"filepath\Domino.Winview.exe");
            p.WorkingDirectory = Path.GetDirectoryName(@"filepath\Domino.Winview.exe");
            Process AppProcess = Process.Start(p);
            ApplicationUnderTest appStartApplication = ApplicationUnderTest.FromProcess(AppProcess); 

2- 

ApplicationUnderTest calcApp = ApplicationUnderTest.Launch(@"filepath\Domino.Winview.exe");

in both the cases its launching the application but throwing below exception: 

Unable to find the main window of the underlying process

解决方案

Hi Kapil_dell,

Welcome to MSDN forum.

After experiment, they could work normally in my side. My running environment: VS2017 enterprise, win10.

May you could use process.start(path) and ApplicationUnderTest.Launch(Path) to try to launch the application. And both of them also can work successfully in my side.

If the issue persists, could you share more details about the project, or I would appreciate that you could share a sample using github or one drive, then I will download and test in my side.

Look forward to your reply.

Best Regards,

Dylan
