问题 I adapted my code below from "Microsoft .NET Compact Framework" by Wigley and Wheelwright: SqlCeConnection cn = new SqlCeConnection(@"Data Source=\My Documents\Traffic.sdf"); String sSQL= "SELECT CarID, Reg, Location FROM Cars"); SqlCeCommand cmdSelect = new SqlCeCommand(sSQL, cn); cmdSelect.CommandType = CommandType.Text; SqlCeDataReader dtr = cmdSelect.ExecuteReader(CommandBehavior.Default); // It's "cmd." instead of "cmdSelect." in the book, but that doesn't compile while (dtr.Read()) {

问题 In my Windows CE app, I have been trying to change all project references from "Any CPU" (or "AnyCPU") to "x86" To do so, I've hand-edited the .csproj file (Project > Properties... only has "Any CPU" available as an option, no "x86" (or anything else).

问题 Windows Mobile 6 single instances applications by default can I turn off or override this behavior? This is needed if one needs to automatically restart or self update an application. 回答1: Alex Feinman describes how it works, and how to get around it, in this blog post 回答2: This is needed if one needs to automatically restart or self update an application.

问题 I have a .NET CF 1.1 application that has been running perfectly fine for years. Occasionally, I get a help desk ticket with the following error message (generic): Method not found: MethodName AssemblyNamespace.Class The DLL is there, and it's the same version as my other devices. What could change that would make it not find the method. Does this error imply that the assembly was loaded, or did it break before that even happened? Does it matter how I added the reference in Visual Studio

问题 Im trying to build a simple XML to Controls parser in my CF application. In the code below the string im trying to parse looks like this: "<Panel><Label>Text1</Label><Label>Text2</Label></Panel>" The result i want with this code would be a Panel with two labels. But the problem is when the first Label is parsed the subreader.Read() returns false in the ParsePanelElementh method, and so it falls out of while statement. Since im new into XMLReader i must be missing something very simple. Any

问题 I'd like my compact framework application to show a notification bubble ONLY when it's running "in the background". The application has several forms which may or may not be visible at any time. I'd like the notification handler (which runs on background separate thread) to be able to tell if any form from my application is currently visible on the screen. Is there a simple way to do this that I'm missing? 回答1: You can always monitor when the Forms and Processes change from your app and act

问题 Since our application grows, we need more space on our Windows CE devices. We installed SD-Cards. Running our applications from the sd card is slow and there are some heavy issues with demand-paging if you run the apps from persistent paths. The only option we see is to install the Compact Framework on the SD cards to free some memory. Is it worth to install it there? Will we get performance problems? 回答1: It really depends on what value you're using for "worth". Installing the CF onto a

问题 I am writing a library which is a set of classes meant to be shared between many different .NET applications, including at least one which uses the .NET compact framework. I have been making these classes use the [DataContract] attribute with a bunch of [DataMember]s so that they are easy to serialize and deserialize using the DataContractJSONSerializer. I have been searching the web to try to find out if this functionality (DataContractAttribute, DataMemberAttribute, and

问题 Is it possible to add a button to a column in the DataGrid for the compact framework? So far the only thing I can find is you can add textbox and that's it. What would be a good alternative to a DataGrid that can allow other controls? 回答1: You can use the DataGrid's public Rectangle GetCellBounds(int row, int col); with public event EventHandler CurrentCellChanged; public DataGridCell CurrentCell { get; set; } or public event MouseEventHandler MouseMove; public HitTestInfo HitTest(int x, int

问题 I'm working in Windows Mobile 6 and would like to have client authentication when talking to a Apache webserver. I have a certificate in my local certificate store and it should be rather straightforward: X509Store myStore = new X509Store("MY", StoreLocation.CurrentUser); myStore.Open(OpenFlags.ReadOnly); X509Certificate2Collection certificates = myStore.Certificates; X509Certificate2 clientcertificate; foreach (X509Certificate 2certificate in certificates) { clientcertificate = certificate;
