Some platforms look at // this

问题 I have hardware with Microsoft Embedded Windows CE 4.1 (CE .NET) / CPU Intel XScale PXA250 / Memory 32 MB RAM/32 MB ROM. Is there possible to run .NET CF 3.5 on hardware this type? Or may be only .NET CF 2.0? 回答1: it seems that there is a version for Windows CE 4.2, it may work also on 4.1 because there are no major differences in the kernel between those two releases: http://support.microsoft.com/kb/947559 It's not granted that it could run on any Windows CE 4.2 device. The .NET CF requires

问题 I write commands to a belt printer using OpenNETCF.IO.Ports.SerialPort this way: public static bool SendCommandToPrinter(string cmd) { bool success; // init'd to false by default try { SerialPort serialPort = new SerialPort(); serialPort.BaudRate = 19200; serialPort.Handshake = Handshake.XOnXOff; serialPort.Open(); serialPort.Write(cmd); serialPort.Close(); success = true; } catch // may not need a try/catch block, as success defaults to false { success = false; } return success; } ...now I

问题 I'd like to automate importing cert(s) on a Windows CE device. Pushing the certs down to the devices is not a problem, but once they are there I cannot determine how to import them without using the UI. (I'm currently using Avalanche Mobility Center) 回答1: Another way to push certificates onto windows mobile devices is to use Windows Mobile Device Provisioning. MSDN Provisioning Mobile Devices Article For examples of certificate provisioning, in any of the Windows Mobile SDK directories, there

问题 We've developed a .NET 3.5 CF Application and we're experiencing some application crashes due to unhandled exceptions, thrown in some lib code. The application terminates and the standard application popup exception message box is shown. Is there a way to catch all unhandled exceptions? Or at least, catch the text from the message box. Most of our customers simply restart the device, so that we're not able to have a look on the exception message box. Any ideas? 回答1: Have you added an

问题 When attempting to run the Windows CE 5.0 emulator on my 64-bit system, I get the following error: "Emulator for Windows CE is incompatible with the host operating system. Emulator for CE will not run on 64-bit host operating systems.64-bit host operating systems." How can I run the Windows CE 5.0 Emulator under 64-bit Windows 7 without resorting to a VM? 回答1: You can't. The old CE 5.0 emulator is an x86 emulator and must run on a 32-bit target. If you need to run on a 64-bit machine, use

问题 I'm trying perform a relatively basic TCP socket send/receive operation on Windows CE using the .NET Compact Framework. I'm trying set the timeout value so that reads/writes on a slow connection timeout instead of blocking forever. On the full framework I'm able to simply set the ReceiveTimeout and SendTimeout properties on the Socket object. Unfortunately, setting these properties on the compact framework immediately results in a SocketException about using an unsupported socket option.

问题 I'm developing an application for mobile devices (Windows CE 5.0, .NET compact framwork 2.0 pre-installed) using .NET compact framework 3.5 and MS Visual Studio 2008. I'm using the built-in option for creating localized forms. This works perfectly as long as I use the debugging function of Visual Studio with the mobile device connected to my desktop computer. In this case, Visual Studio deploys my application along with .NET compact framework 3.5. After disconnecting the mobile device and
