问题 I've got a .NET CF (C#) mobile application that I run on a windows emulator. This application uses a sqlce database, and also is controlled by a number of config-like files. I frequently need to change back and forth between different debugging environments - i.e. I need different versions of the database as well as the config files - b/c the application is being used differently in each of the environments. My initial thought was to use different emulators for different environments, but

问题 This is a "problem" i have with data that i receive from a library that has some Async operations on sending and receiving data. While i receive data and get data in my Mobile Windows Form or Desktop i need to deal with the cross thread operation. I deal with this while checking InvokeRequired and do Action if true...etc...But, what i really would like is to make this disappear and get my data correctly so i could bind them manipulate etc, without handling this cross-thread problem. Question

问题 Afternoon people! I'm trying to implement a list of counties on my Compact Framework (Mobile) application. I can do this easily in the full .Net framework with CultureInfo.GetCultures(..etc). However, the CF seems to be missing this feature? Is there any way I can return a list of countries (and regions if possible) that I can populate into a ComboBox? The OS has a list of countries, so there must be a way to do it? I look forward to hearing back! 回答1: How about this? using System; using

问题 I need to determine how much free space there is on a Windows CE device, to conditionally determine whether a particular operation should proceed. I thought Ken Blanco's answer here (which bears a striking similarity to the example yonder) would work, which I adapted as: internal static bool EnoughStorageSpace(long spaceNeeded) { DriveInfo[] allDrives = DriveInfo.GetDrives(); long freeSpace = 0; foreach (DriveInfo di in allDrives) { if (di.IsReady) { freeSpace = di.AvailableFreeSpace; } }

问题 I was first getting "Unable to connect to the remote server" but then remembered that I couldn't use "localhost" from a handheld device. I swapped that out with the name of the machine like so: String uri = String.Format(@"http://PLATYPUS:21608/api/inventory/sendXML/woodrow/gus/{0}", fileName); //I reckon I could also use the IP address in place of the machine name, but probably would make no difference ...and now I get, " The remote server returned an error: (400) Bad Request " The same

问题 we decided to design a keyboard(bluetooth or data cable) for using on a smartphone. so, can we programming a smartphone by compact framework?is that possible? 回答1: What do you mean by "possible"? If the device has Bluetooth and you have the capabilities of creating a bluetooth keyboard, then certainly it would work. The "programming" part of the question needs clarification, though. You program in Visual Studio on your desktop PC, then compile the app and deploy it to the device. Obviously

问题 I am trying to use the RSACryptoServiceProvider to encrypt/decrypt. Encrypting works fine, but the Decrypt method throws an exception with the message: Unknown Error '80007005'. This is the code: Byte[] plainData = encoding.GetBytes(plainText); Byte[] encryptedData; RSAParameters rsap1; Byte[] decryptedData; using (RSACryptoServiceProvider rsa1 = new RSACryptoServiceProvider()) { encryptedData = rsa1.Encrypt(plainData, false); rsap1 = rsa1.ExportParameters(false); } using

问题 Ive written an application using the .net compact framework. One of the requirements is that a check is run before app runs to see if the compact framework is installed. If not I should prompt this to them and redirect them to cf download location. What would be the best most common approach to doing this. Obviously my .net wont run in the first place if .net cf is not installed, do i need to write this in eVc++? Much appreciate your thoughts on the Tony 回答1: This is an MSDN article about
