微软.net精简框架常见问题及回答(中文版)(36)
10.3. 使用微软.net精简框架开发移动游戏
Learn how to create .NET Compact Framework-based games. Learn the key requirements for writing games targeting small devices and see that the .NET Compact Framework can handle them with ease. Include advanced performance-tuning techniques that you can use to push the limits of your game.

10.4. 制作一个微软.net精简框架的DateTimePicker控件
Learn how to use a managed DateTimePicker class in your Pocket PC projects. The .net精简框架 provides managed classes for most controls but the DateTimePicker class is not supported. Wrapper classes that P/Invoke the native control can be found on the Web, but this sample provides a purely managed DateTimePicker class that you can use in your Pocket PC projects. The class and sample application are provided in C# and Visual Basic .NET.

10.5. 写一个捕捉Pocket PC签名的程序.
This article discusses the Pocket PC Signature sample application. The sample includes a client that runs on the Pocket PC that sends signature data over TCP sockets to a server that is running on the desktop. Data is encrypted and decrypted using the cryptography services.

11.1. 为什么不同通过ActiveSync把程序部署到Windows CE的设备上？
Symptom: When a Windows CE device is connected through ActiveSync, deployment and debugging (F5 and Ctrl-F5) fail with the typical error message "There were deployment errors. Continue?"
Cause: Due to the fact that ActiveSync 3.5 and 3.6 do not provide accurate information about the device instruction set, ConMan (Visual Studio .NET 2003 component for device connectivity) cannot use the information returned by ActiveSync to map a Windows CE device to the right .NET Compact Framework target (MIPSII, ARMV4 etc).
Workaround: Install and run the separately provided Windows CE Configuration Add-In. For ARMV4 devices, an alternative is to select Pocket PC Device at the beginning of the deployment.
11.2. 为什么不能通过ActiveSync调试 CEPC 或其他 x86 的Windows CE设备？
Symptom: After running the Windows CE Device Configuration Add-In, the user can deploy without debugging (Ctrl-F5) to an ActiveSync connected CEPC (or any x86 based Windows CE device) but cannot debug (F5). Non-x86 based Windows CE devices do not have this problem.
Cause: Debugging Windows CE Emulators (also x86 based) uses a TCP port that conflicts with the one used by ActiveSync for debugging x86 based devices. To support Emulator debugging, it is necessary to disable debugging for CEPC and other x86 devices by default.
Workaround: The following workaround will allow debugging of x86 devices but disable debugging with the Windows CE Emulator. The workaround requires the files WinCEx86Device.reg, and ProxyPorts.reg which can be found in the SDK utilities directory: "<VSROOT>\CompactFrameworkSDK\WinCE Utilities\WinCE Proxy Ports Reg".
If you do not have these files they can be downloaded from the following link:
Import WinCEx86Device.reg to the registry. Now you will be able to debug x86 devices, but debugging with the Windows CE Emulator will fail.
To restore Emulator debugging, remove the registry key "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows CE Services\ProxyPorts" and then import ProxyPorts.reg.
11.3. 为什么当设备上的Toolhelp.dll文件丢失后，调试就会失败？
Symptom: After F5, all the files including the application executables and .net精简框架 cab files are copied to the device, and the IDE reports success on launching the application, but nothing is launched on the device. If you check the \windows folder of the device, toolhelp.dll does not exist.
Cause: Some device images may not include toolhelp.dll which is required by SDE debugging.
Workaround: Copy toolhelp.dll from Windows CE SDK to the \windows folder of the device. This file can be found in the corresponding target directory for each device.
For example, for an ARM device: "<VSROOT>\CompactFrameworkSDK\WinCE Utilities\ToolHelp\WinCE4\armv4".
If you do not have this file it can be downloaded from the following link:
11.4. 为什么当网络协议数超过５０个的时候，就不能向设备发布程序？
Symptom: The "deployment error" message box occurs on Ctrl-F5 or F5. Running EnumProtocols.exe lists more than 50 protocols. (EnumProtocols.exe can be found in the WinCE utilites directory: "<VSROOT>\CompactFrameworkSDK\WinCE Utilities\EnumProtocols"). If you do not have this file it can be downloaded from the following link:
Cause: It is a known issue that the .NET Framework method System.Net.Dns.GetHostName throws an exception when there are more than 50 network protocols installed on the current machine. The method is called by ConMan and the exception causes failure of the ConMan transport initialization.
Workaround: Uninstall the network protocols that are not actually needed. One way to do this is to go to Device Manager (Right-click on "My Computer", select Properties->Hardware and press the "Device Manager" button) and remove unused entries under "Network adapters". Another way is to uninstall applications that have installed protocols. Those applications can be found from the output of EnumProtocles.exe.
11.5. 为什么卸载ActiveSync后，不能通过ActiveSync向设备发布？
Symptom: The "deployment error" message box occurs on Ctrl-F5 or F5 after ActiveSync has been uninstalled. Uninstalling ActiveSync typically happens when the user upgrades ActiveSync, e.g. from version 3.5 to 3.6.
Cause: ConMan relies on some registry values under "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows CE Services\ProxyPorts" for deployment and debugging through ActiveSync. These registry values are removed when ActiveSync is uninstalled.
