    - Problmes reading ComboBox Selected Value I am having unexpected difficulties reading the selected value from a combobox. I have a combobox that is bound to a datasource. ---snip--- sqlDALocation = new SqlCeDataAdapter( "Select distinct col2 FROM Cartons", DataBaseConnection); sqlDALocation.Fill(sqlDSLocation, "Locations"); LocationFilter.DataSource = sqlDSLocation.Tables["Locations"]; LocationFilter.DisplayMember = "col2"; LocationFilter.ValueMember = "col2"; LocationFilter.DataBindings.Add("SelectedValue", sqlDSLocation.Tables["Locations"], "col2"); ---snip--- Which currently correctly populates the combobox with 4 values. When I try to read the current combobox value in the SelectedValueChanged event LocationFilter.SelectedValue.ToString(); It does not return the proper text in all/most cases. The first item in the combobox is NEVER returned and the others are returned almost randomly. I'm sure I'm doing something foolish or missing something obvious. I would appreciate any help someone can provide. Thanks, John Kelsey Tag: Efficient way to get a file size? Tag: 59164

    - New control ... suggestions needed I'm writing my first custom control in VS.Net 2003 (will port to 2005 soon). It will be a textbox control with custom painting. My first question is what control to inherit from? I can't find S.W.F.UserControl for .Net CF. :( That leaves the following (that I can find) as possible base classes: - Control - ContainerControl - ScrollableControl - Panel Given that my control will contain a toolbar, 2 scrollbars, and a custom text area (That's the meat of this custom control), which one should I use? Given that I also want to better understand they choices, why should I pick a particular parent class for this situation? Thanks! Tag: Efficient way to get a file size? Tag: 59156

    - Create a process and end the current process I am trying to develop a tool to help update the application. To do so I need to create a separate process to start an installer. I then need to end the current process, since it will be overwritten by the installation. I have found all the articles on creating a process and have tried using the coredll.dll and OpenNet options, but neither seems to be working. We I look at the processes it seems the main process (the caller) never ends. My belief is that the process I created is somehow still tied to the original process, but I really am unsure. Does anyone know of a solution to this problem. Tag: Efficient way to get a file size? Tag: 59155

    - Dialog Form MsgBox hi, does anybode know how to create a Form like a msgbox? I want to set my own text on the buttons and the size and positions should work like a msgBox. So the 'parent' form may not respond to the close/ok button and the dialog form may not have a close button. I can create such a form but i can disable the 'parent' form (yes al the controls on it ) but the close event still react.

    - UDP Socket buffer issue I am getting a very strange error that only occurs in one particular case as follows: I split an array of bytes and send it as multiple udp datagrams from a socket in very quick succession. They are then received and re-assembled at the other end. For a particular byte array length (before splitting), I get socket exception 10040 on the receiving end telling me that the datagram size was bigger than the receive buffer size, but ONLY if I send the messages without a delay between them. If I do the following -> send message, PAUSE, send message, PAUSE, send message then the message is reassembled fine, leading me to believe that my buffer sizes are correct (255 bytes either end in any case). This also leads me to believe that with multiple datagrams at the port, the sizes are being read incorrectly, hence socket.receive is trying to read part of the next message into the buffer. Does anyone know of this issue? It only seems to occur for a particular byte array length, which I need to investigate. Tag: Efficient way to get a file size? Tag: 59143

    - What is necessary for WM5.0 development? I am using Visual Studio.Net 2003 right now and the Pocket PC sdk. Soon, I'd like to switch to Visual Studio 2005 and target Windows Mobile 5.0 (for Pocket PCs). What edition of Visual Studio 2005 will be necessary to do this? Can I use Express? Is one of the higher versions necessary? Will I need to download a Windows Mobile 5.0 SDK? Or is programming for devices finally included in Visual Studio installation? I have 2005 Beta 2 (not installed yet) and C# Express (not installed yet). If I need a SDK for Windows Mobile, can anyone provide a link to it?

    - Call to web service via Mobile Device with WWAN fails when passing more than 1K size parameter value I have a .net mobile application that makes a call to web service to read/write data from device's SQL CE to SQL2K database. When I call the web service methods with passing small strings, integers as parameters and receive dataset back it is not a problem. But when I pass Dataset as a parameter to a method (even if the dataset is empty) OR strings of size 1K or larger the call fails with following error message "Could not locate resource assembly". I looked up for this error message in Microsoft groups; I found some information about it. As per the recommendation I also deployed the application via Visual Studio .net which also deployed the required System.SR.dll assembly file. But I still get the same error message. Although the same function call works when used 802.11b/g wireless network OR Ethernet. The problem seems to occur only when using GPRS/WWAN network. The network team has monitored the traffic from the device to the server and confirmed that there is no data/packet loss. Is anyone aware of this issue? Any workaround/fix for this? FYI: I am using Pocket PC - Windows CE 4.0 on mobile device (manufactured by Intermec). The application is developed in VB.Net with .Net framework 1.1 Tag: Efficient way to get a file size?

    - HP iPAQ and Bluetooth Stack I've got a HP iPAQ h5550 and I've today noticed that this hellish device does not use Microsoft's Bluetooth Stack. I think it uses Widcomm's Bluetooth Stack. What a pain! Therefore, I cannot use "open-source" libraries such as Peter Foot's or OpenNETCF's. Which are my options guys? Pay for a commercial DLL such as High Point Software's BTAccess? I can't believe my eyes! Having an iPAQ is really a pain when developing for it! The problem is I must support as much devices as possible, but I think it's very nasty to have to use a commercial DLL to some of them (iPAQ) and Peter Foot's libray for the rest.

    - New projects in VS.NET 2005 I've today installed VS.NET 2005 Beta2. I'm now located at "New Project" window, inside Visual C# and Smart Device section. There are 3 sub-groups here: 1) PPC 2003 - "A project for creating a .NET Compact Framework 2.0 forms application for Pocket PC 2003 and later". I understand a Device Project targeting PPC 2003 will work without problems in Windows Mobile 2003, Windows Mobile 2003 SE and Windows Mobile 5.0. 2) Smartphone - "A project for creating a .NET Compact Framework 1.0 forms application for Smartphone 2003 and later". Only supporting CF 1.0? I suppose it's because I'm working with Beta 2. 3) Windows CE 5.0 - "A project for creating a .NET Compact Framework 2.0 forms application for Windows CE 5.0 and later". If I want to develop an application that can target Windows Mobile 2003, Windows Mobile 2003 SE and Windows Mobile 5 and can run in as much devices as possible, I understand I should choose Option 1, that is, PPC2003. Is the most common choice for developers with same requirements I have? Could somebody explain me a little bit this mess of new projects? What else does "Windows Mobile 5.0 SDK for Pocket PC" give me? Only emulators? And finally, would be possible to develop an application that could run both on PocketPC and SmartPhone?

For example, I've created the following: namespace IImageTesting { [ComImportAttribute()] [GuidAttribute("0000000c-0000-0000-C000-000000000046")] [InterfaceTypeAttribute(ComInterfaceType.InterfaceIsIUnknown)] public interface IStream { int Read(IntPtr buffer, int numBytes, out int numRead); int Write(IntPtr buffer, int numBytes, out int numWritter); int Seek(long position, int origin, out long newPosition); int SetSize(long newSize); int CopyTo(IStream pstm, long numBytes, out long numRead, out long numWritten); int Commit(int commitFlags); int Revert(); int LockRegion(long offset, long numBytes, int lockType); int UnlockRegion(long offset, long numBytes, int lockType); int Stat(ref StatStg statBuf, int statFlag); int Clone(out IStream stm); } } And then use it here: [ClassInterface(ClassInterfaceType.None)] public class StreamInIStream : IStream { private Stream _stm; public StreamInIStream(Stream stm) { _stm = stm; } #region IStream Members // boring details removed for brevity #endregion } in this context: FileStream stm = new FileStream("\\Program Files\\IImageTesting\\4bit.bmp", FileMode.Open); StreamInIStream istm = new StreamInIStream(stm); factory.CreateImageFromStream(istm, out blah); At this point, CreateImageFromStream crashes the session with the wonderfully descriptive error number 800704ca, which gives me this if I search for it through the SDK header files: Find all "800704ca", Match case, Subfolders, Find Results 1, "WinCE 5.0 includes", "*.h" Matching lines: 0 Matching files: 0 Total files searched: 551 Ideas? I'd like to be able to author my own codecs and image sinks in .NET, but this isn't giving me warm fuzzies about that process. Tag: Efficient way to get a file size? Tag: 58977

What's the most efficient way to get the size of a file in dotnet CF?

Use the FileInfo class and it's length property e.g.

[C#]
FileInfo fi = new FileInfo("\\My Documents\\todo.txt");
long len = fi.Length;

[VB]
Dim fi As New FileInfo("\My Documents\todo.txt")
Dim len As Int64 = fi.Length
