微软.net精简框架常见问题及回答(中文版)(77)
11.10. 为什么在模拟器刚开始运行的时候出现关于找不到文件的错误信息？
Symptom: When the Emulator is being started, a message box appears titled "Emulator for Windows CE" with the text "One or more files from the Emulator for Windows CE installation is missing. Please reinstall Emulator for Windows CE and try again." The connection or deployment to the Emulator will fail after the message box.
Cause: A typical cause is that the Emulator driver is not installed or is corrupted.
Workaround: Go to "Device Manager" (Right-click on "My Computer", select Properties->Hardware and press the "Device Manager" button) and check whether "Virtual PC Application Services" is installed under the System Devices group. If the driver is not installed, install it by running "<VSROOT>\CompactFrameworkSDK\ConnectionManager\Bin\DriverInstall\Smart Devices Emulator.msi".
Note: Verify that the "Virtual PC Application Services" appears after running the msi file. If not then reboot the PC and attempt the installation again.
11.11. 为什么第一次用模拟器发布时，会出现偶尔的错误？
Symptom: The startup of the Emulator is slow and the deployment eventually fails with a connection error message. The startup mainly includes starting the Emulator image and downloading the .net精简框架 files. The failure happens more often on low-end machines when the Emulator is used for the first time or after "turn off" instead of "saving state" was used on the previous Emulator shutdown.
Cause: Due to some performance issues in the Emulator, its startup may take too long to finish within the ConMan timeout period.
Workaround: If possible, always choose "saving state" instead of "turn off" when closing the Emulator so that the startup will be much faster when the Emulator is started next time. Or before the deployment, pre-start the Emulator by clicking on the "Connect to Device" button which is located next to the Emulator name on the menu bar. Note that the first deployment will still fail after the pre-start. (See details in the issue about this.) In addition, hovering the mouse over the Emulator image may speed up the Emulator startup.
11.12. 为什么第一次用Connect按钮连接模拟器并发布程序的时候失败了？
Symptom: When the Emulator is started with the "Connect to Device" button, the first deployment attempt always fails.
Workaround: There is no workaround at this point for the failure of the first deployment after the Emulator is started with the button, but the subsequent deployment attempts should succeed.
11.13. 为什么当计算机没有网络连接的时候，用模拟器调试程序会出现错误？
Symptom: When a machine has no active network connection, debugging with the Emulator (F5) does not work, while deployment without debugging (Ctrl-F5) works fine.
Cause: Emulator debugging relies on TCP transport.
Workaround: Install the Microsoft Loopback Adapter on the machine.
To install the the Microsoft Loopback Adapter in Microsoft Windows XP
Open Control Panel, choose Add Hardware, and then choose Next.
Choose Yes, I have already connected the hardware, and then choose Next.
From the Installed hardware list, select Add a new hardware device, and then choose Next.
Choose Install the hardware that I manually select from a list (Advanced), and then choose Next.
From the Common hardware types list, select Network adapters, and then choose Next.
From the Manufacturer list, select Microsoft.
From the Network Adapter list, select Microsoft Loopback Adapter, and then choose Next.
Choose Next, and then choose Finish.
To install the Microsoft Loopback Adapter in Microsoft Windows 2000
Open Control Panel, choose Add/Remove Hardware, and then choose Next.
Choose Add/Troubleshoot a device, and then choose Next.
From the Devices list, select Add a new device, and then choose Next.
Choose No, I want to select the hardware from a list, and then choose Next.
From the Hardware types list, select Network adapters, and then choose Next.
From the Manufacturers list, select Microsoft.
From the Network Adapter list, select Microsoft Loopback Adapter, and then choose Next.
Choose Next, and then choose Finish.
11.14. 为什么当模拟器使用了一个COM端口的时候不启动不了(黑屏)？
Symptom: When the Emulator image is starting up, it stays as a black screen forever. This happens when the Emulator is configured to use at least one COM port.
Cause: By default, the Emulator is not assigned a COM port but the user may change the configuration to assign a COM port to the Emulator. When a COM port assigned to the Emulator is used by ActiveSync or any other running application, the Emulator image loading will fail.
Workaround: Remove all of the COM ports assigned to the Emulator or change them to those not used by ActiveSync or any other running application. To remove or change the COM port configurations in Visual Studio .NET 2003, go to Tools/Options/Devices, choose an Emulator in the Devices window and click the Configure button.
11.15. 为什么Visual Studio .NET 2003的模拟器不能和eMbedded Visual Tools的模拟器同时使用？
Symptom: When the eMbedded Visual Tools (Platform Builder) Emulator is running, Visual Studio .NET 2003 Emulator deployment fails, and vice versa. Sometimes even after the Visual Studio .NET 2003 Emulator is closed, the eMbedded Visual Tools Emulator still does not work.
Cause: The Visual Studio .NET 2003 Emulator and the eMbedded Visual Tools Emulator internally use two different instances of Emulator.exe which are not compatible with each other. Because they share the same executable name and the exe is a single instance application, while Emulator.exe for eMbedded Visual Tools is running, the one for Visual Studio .NET 2003 cannot be started, and vice versa. Another issue is that when the Visual Studio .NET 2003 Emulator user interface is closed, emulator.exe does not close until the hosting Visual Studio IDE instance is closed. In that case, the eMbedded Visual Tools Emulator cannot be started even though there is no Emulator running visually.
Workaround: Do not use the two Emulators at the same time. If an Emulator cannot be started, check the Task Manager and close any running emulator.exe processes.
11.16. 为什么没有ActiveSync连接的时候不能通过TCP连接向设备发布程序？Symptom: When a device does not have an ActiveSync connection with the Visual Studio machine but has a valid TCP connection, deployment does not work.
Cause: ConMan relies on an ActiveSync connection to perform some initial settings between the Visual Studio machine and the device. If no ActiveSync connection is available, the setting will have to be performed manually.
Workaround: Use the separately provided Keyman tool to perform the initial device settings with the following steps:
Choose the correct flavor of Keyman.exe (e.g. ARMV4 or SH4, etc) and place it on the device. Launch Keyman and select "FILE->CONNECT". Keyman is now waiting for the VS machine to connect to it via TCP/IP. After the VS machine has connected, and then disconnected, Keyman on the device will automatically exit.
On the VS machine, copy CryptoAPIWrapper.dll from <VSROOT>\ CompactFrameworkSDK\ConnectionManager\bin to the directory of KeymanDesktop.exe. Launch KeymanDesktop.exe.
Click "Save" to save your settings in the current directory where KeymanDesktop.exe is running. The saved defaults will be loaded next time the exe is launched.
Enter the IP Address of the device
Use the recommended value for the Device Port.
Enter the path of the "Target" directory where the ConmanClient bits such as ConManClient.exe reside. The typical value is \ CompactFrameworkSDK\ConnectionManager\Target.
Use the Connect button to connect.
Click on "prep device" after you have connected. On success, you will see a dialog telling you everything went OK.
Use the Disconnect button to disconnect. When you disconnect, the device side bits will automatically exit.
Launch ConManClient.exe on the device. First you must select the flavor of the target device. Also, you must select the location of your "Target" directory in Visual Studio. 11.17. How can I allow Activesync to connect to an Emulator session from Visual Studio .NET 2003?
