    - NTML authentication protocol Hi to all I need to configure User/Password for access to device in LAN. The device is a board with ARM processor and NIC 10/100. On the board there's a DOM (disk on module). Some client need access to Hard Disk (the DOM) where my application write some data. My application is write in VB.NET 2005 and the O.S. is WinCE 6.0. In order to setting the file server I would want to know as I can manage customers and password from my application (which libraries and/or instructions allow me to read, to write, to cancel, to insert the credentials ?). How can i permanently store the credentials into registry ? (how must i set up the OSDesign ? Hive-base registry, ecc... ?) Thank you very much Ale Tag: How to convert a 3.1 database to a 3.5 database ? Tag: 85220

    - Problems reading fast enough from serial port Hi there, I am developing an application for a mobile device and have to receive data via bluetooth and the serial port profile. I am currently programming in c#. The device is a Windows Mobile 6 device. (Moto Q 9h) I can receive data but the problem is it is way too slow. I get a data package with 6 byte every 8ms but when reading it, the ReadBuffer fills more and more. Later I should receive twice as much data. I wanted to use serialPort.ReadLine() to get each packet each own. (5 byte data + 1 newline) I tried it with the serialPort.DataReceived eventhandler but I get a lot of messages like The Thread ... has stopped with code 0. Der Thread 0x9ed3e02 hat mit Code 0 (0x0) geendet. Der Thread 0x9ed3e02 hat mit Code 0 (0x0) geendet. Der Thread 0x9ed3e02 hat mit Code 0 (0x0) geendet.

I have to restart the device to make it run once again. I also tried to handle all the data aquisition with a worker thread wich polls the comport and handles incoming data but it is also way to slow and the gui does not respond anymore. Any hints on how to improve my program? The serial port is running with private SerialPort serialPort; private int baudRate = 57600; private Parity parity = Parity.None; private int dataBits = 8; private StopBits stopBits = StopBits.One; Thanks in advance Flo Tag: How to convert a 3.1 database to a 3.5 database ?

    - Strange ComboBox behavior Hi all, I'm using a ComboBox control in a DropDown mode (one with both TextBox for free-text-entry and a drop-down-list) and is trapping the TextChanged event to process the value being entered. As far as I can tell, when the Text property is accessed from the TextChanged event, it should return the post-change value. Well, it does for the most part, but occasionally, the old value (before the change) is returned. This seems to happen only when the text is highlighted (which is the default behavior when the control gets the focus). I don't have a real mobile device handy, so I could not verify if this behavior is happening only on the emulator. Is anyone aware of this quirk? Any information on it? Thanks. - Jin Tag: How to convert a 3.1 database to a 3.5 database ? Tag: 85205

    - Cancelling a file download using HttpWebRequest Hi all, I have some code running on the Pocket PC (w/CF v2.0) that grabs a file (about 20 MB) from the server using HttpWebRequest. I want to give to user the possibility to cancel the download (the download method is running in another thread which is aborted when the user cancels). From what I understand, to close everything gracefully requires calling Abort() on the HttpWebRequest object and/or Close() on the WebResponse object. Failure to do so will interfere in the subsequent attempts to download the file. But here goes, calling either of the methods seems to hang the device, but in fact I think there is some cleanup going on in the backgroup. BUT, from a user point of view, it changes nothing. Is there a bug in the CF because the same code works A1 on the desktop. Has anybody been able to work around this, or am I simply missing something? Thanks. Here's a lean version of the code: private void DownloadFile() { HttpWebRequest request = null; WebResponse response = null; Stream stream = null; FileStream fs = null; try { request = (HttpWebRequest)WebRequest.Create(_remoteFileUrl); request.KeepAlive = false; response = request.GetResponse(); stream = response.GetResponseStream(); string localFilePath = Path.GetTempPath() + Path.GetFileName(_remoteFileUrl); fs = new FileStream(localFilePath, FileMode.Create); int total = 0; byte[] buffer = new byte[0x1000]; while (true) { int currentRead = stream.Read(buffer, 0, buffer.Length); total += currentRead; fs.Write(buffer, 0, currentRead); if (currentRead == 0) { break; } } } finally { fs.Close(); response.Close(); request.Abort(); } } Tag: How to convert a 3.1 database to a 3.5 database ?

    - Top Five OpenNETCF I've just now started to get into the Smart Device Framework and was wondering what the top five or ten handiest features were from those that have really gotten into using it. I've got a chance to completely rewrite an app which scans, prints, needs to transparently sync incrementally, will use a web service and also RDA Pull . Are there features that have made life a lot easier that are your favorites? TIA Harry Tag: How to convert a 3.1 database to a 3.5 database ? Tag: 85194

    - quickstart tips for smartphone development Hi, We'd like to create an app for a mobile phone using the .NET CF. Can you please post a few quick tips or links on the following issues: - How do you typically access (if at all) phone functionality such as vibration-alarm or other phone-specific functionality? Do you need DLLs from the phone-manufacturer, and do they typically provide them freely? - We have experience with C# and Visual Studio, are there good starting points that point out typical traps? If I need to provide more/other/specific info please let me know. Thanks. -Jeroen Tag: How to convert a 3.1 database to a 3.5 database ? Tag: 85173

    - Cannot use "Tab" button in textbox to foucs on other control Hi! All. I got some problem in developing .net CF program. My situation is that. I have two Textboxes in a form, my boss need me to well define the tab index although it is a smart device program. However, in some cases, after I inputted some characters in the a textbox and then I press "Tab" button either my keyboard or emulator input keyboard, the program is still focused on the original textbox but not focused on the next textbox or control. I found that if I input one alphabet or some 2 and 3 alphabet combination, the problem occurred. If I input more than 3 alphabets, the "Tab" button work normally. Is this the bug of .net CF? Can it be solved? Thanks for help. Tag: How to convert a 3.1 database to a 3.5 database ? Tag: 85172

    - Timer Tick in compact framework I am experimenting with some graphics using vb.net/compact framework. I have a Timer which is supposed to fire every 100 milliseconds to update a graphic. When the application runs (in either the runtime as a emulator or on the actual PDA) the graphics only update once per second. Is there some limitation to the timer? The timer shows the interval as being 100 yet the graphics do not update that fast. They do update exactly once each second. There is little actually going on for this animation (drawing a couple of lines) Is there some way to get the event to fire more rapidly? Tag: How to convert a 3.1 database to a 3.5 database ?

I'm programming an application for my navigation system. 1) Development tool is: MS Visual Studio .Net 2003 - SP1 2) Navigation system is equipped with: a) MS Windwows CE .net 5.00 b) MS .NET Compact Framework 1.0.4292.00 I've a question for you: I wish to "start external program" programmatically, on button click event. I'm Visual Basic v. 6.0 expert and Shell(), ShellExecute() and ShellExecuteEx() were very useful, but into vb.net language they are not!??? I wish the vb.net equivalent of vb60 instruction: retVal=Shell("\MySubDir\Notepad.exe", vbShow) I've tried "ShellExecute API" but gives me a NotSupportedException I've tried to use "Process class" but I've not found it into CF.

    - Native Error w/ CF2 SP2 I've got an app that I deploy to a symbol MC70 device running Windows Mobile 5. The device actually comes with CF1 SP3 RTM on it. I have installed the CF2 RTM cab file NETFv2.wm.armv4i.cab 2/2/2005 and it installs the CF2 RTM 2.0.5238.0 just fine and the applications works great. The problem is when I substitute the CF2 SP2 cab and install 2.0.7045.0 - I then try to start up my application and the program errs out before it can even stop with a natve error in the application exe message. How does VS2005 get updated to compile and run against CF2 SP2 environment? Why can't I run my app after CF2 SP2 is installed?? TIA Harry Tag: How to convert a 3.1 database to a 3.5 database ?

    - Problem with datagrid - ObjectDisposedException when second time dispose Hello, I am still learning C#, so please bear with me. I have a two Form, from first I open second form with datagrid. When I Dispose datagrid second time I get a ObjectDisposedException. In first (main) form I have a button with code under onclick event: temp_n = this.Text; this.Text = string.Empty; Form1 frm1 = new Form1; frm1.ShowDialog(); frm1.Dispose(); this.Text = temp_n; and in second form: private void Form1_Load(object sender, EventArgs e) { ceCmd = Global.DatabaseConnection.CreateCommand(); ceCmd.CommandText = "select col1,col2 from table"; ceCmd.CommandType = CommandType.Text; ceResSet = ceCmd.ExecuteResultSet(ResultSetOptions.Scrollable); dataGrid1.DataSource = ceResSet; } and private void Form1_Closed(object sender, EventArgs e) { if (ceResSet != null) { ceResSet.Close(); ceResSet.Dispose(); } if (dataGrid1 != null) dataGrid1.Dispose(); } and when I twice opened and closed second Form i get a ObjectDisposedException on "if (dataGrid1 != null) dataGrid1.Dispose();" it's strange to me because when i put button on second form and add event: private void Button_Click(object sender, EventArgs e) { if (ceResSet != null) { ceResSet.Close(); ceResSet.Dispose(); } if (dataGrid1 != null) dataGrid1.Dispose(); this.Close(); } everything is OK. So i tried put datagrid1.Dispose() on override OnClosing and override OnClosed but with no change - DisposedException still occurs. So, what I'm doing wrong?

    - Function key stuck on in Windows Mobile 6 device in Textboxes I have a very strange problem with a new Sprint 6800 Windows Mobile 6 device. When I use the popout keyboard, it always acts like the function key is stuck on. This happens in a single line or multi-line textbox. The SIP works fine. The Fn light goes on and off when I press the Fn (blue dot) key, but the keystrokes always show up as if the function key was on. This same app works fine on at least 10 other mobile device models that we have deployed. The keyboard works fine in all other apps (Word, notes, contacts, etc.), so it seems to be a .NET related issue. I have Googled the problem and came up with nothing. Any idea what to try??

    - HttpWebRequest in .NET CF 2.0 - Sent XML File over 34K Corrupted I have a .NET CF 2.0 Mobile Application that sends "collected data" to a HTTPS Server (running Apache under Windows 2000) and the XML file (SOAP) containing the collected data "occasionally" appears corrupted on the server side, but only when the XML file is greater than 34K in size, and cannot be properly parsed as an XML Document due to missing / corrupt XML Tags. I say "occasionally" because I cannot reproduce this error myself and only a few of our customers (2-3 out of 70) using the mobile application have experienced this situation. The XML file is never corrupt as long as it is under 34K in size. In an attempt to reproduce this error I have sent "collected data" files as large as 125K without any XML errors and did so using various Internet Connections, i.e. using our corporate intranet, the Internet via ADSL from my home and using ActiveSync running on a Desktop Machine connected to our intranet and the Internet. I have NEVER been able to reproduce this error which led me to believe that the problem was due to hardware failures of the mobile device itself or the customers network, but after extensive research and testing this does not appear to be the problem either. Also, the "collected data" itself does not contain any characters that would violate the XML standard and I went so far as to add some code to the mobile application that validates the XML Structure prior to sending the data to the host server and the structure is always validated before sending but arrives at the host server corrupted!! I am assuming that the HTTPS / TCP/IP protocols will handle corrupt packets via the packet checksum and request the packet again, so I don't think data is being corrupted during its trip to the host server but instead is actually corrupt when being transmitted from the mobile device itself, hence the packet checksums are always correct. The mobile device is a Symbol MC3090 running WinCE 5.0 and Symbol (now Motorola) has no mention of any "data corruption" within their knowledgebase regarding these devices. I have read the Microsoft Article (ID 831578) regarding "Memory Leak When SSL and Client Certificates are Used With the HttpWebRequest Object" but am unsure if this applies to the .NET CF 2.0. We are using HTTPS / SSL and I am using the standard example given for the LocalCertificatePolicy.CheckValidationResult to eliminate certificate problems such as mismatched certificate and machine names but I do not ignore an invalid certificate. Originally I was using .NET CF 1.1 when I created this application and ran into a .NET CF bug regarding the use the HttpWebRequest class over HTTPS whereby the workaround was to set AllowWriteStreamBuffering = True and to not specify the ContentLength property. Even though the project has been upgraded to .NET CF 2.0 I am still abiding by the workaround for the .NET CF 1.1 bug. Is this still an issue in .NET CF 2.0? An example of the corrupted xml data: (closing tag of </ItemEnterpriseName> is corrupt and opening <ItemName> tag is missing along with the data itself) <Name>DEFAULT</Name> <ItemEnterpriseName>Comtech Data</ItemEnterpriseNa4A</ItemName> <SiteEnterpriseName>Comtech Data</SiteEnterpriseName> ... data continues ... The data should have appeared as: <Name>DEFAULT</Name> <ItemEnterpriseName>Comtech Data</ItemEnterpriseName> <ItemName>IC/SO-NC7SBU3157</ItemName> <SiteEnterpriseName>Comtech Data</SiteEnterpriseName> ... data continues ... Any assistance in the matter would be tremendously appreciated!!! Thank you, Greg Hellem Tag: How to convert a 3.1 database to a 3.5 database ? Tag: 85046

    - HTC S710 I have an app running WM6 Standard on HTC S710. I open a form to enter text in landscape mode. If I enter info using slide out QWERTY, then slide back in and click 'Cancel' to close form (me.close) I get what seems to be a HTC Task screen. If I use the 'Back' button the Task screen closes and I get my parent form. Is anyone else experiencing something similar? Thanks. Tag: How to convert a 3.1 database to a 3.5 database ? Tag: 85044

    - Vista advice needed I need to invest in a new laptop and a large majority of the ones (especially the DELL XPS) are now running Vista. I've had vista running on my PC at home for a while now and certain things just doesn't really work well, such as VS.NET 2005. Mobile development doesn't seem to work the same as on XP either. How have you guys found the migration went from XP to Vista? Should i just stick with what i know best, XP ? Any advice greatly appreciated Tag: How to convert a 3.1 database to a 3.5 database ?

    - Button Click & Listview events not triggered Hi. We have a smart device app written in VB.NET, CF2.0 which has a form with listview & buttons. On this particuar form, sometimes when you click the listview or the buttons, the Listview.SelectedIndexChanged & Button.Click events are only triggered the second time you click them. Sometimes it's the first time. We want it triggered on the first click. We've tried the listview.activation property set to standard, oneclick & twoclick. no effect. Cant see anything else on the button, listview or form properties which may relate to this. Also, this is only happening on one form, and not others in the same app. Does anyone have any suggestions of what may be the cause?? Thanks. Ian.

    - Mac or Unquie ID We have written an application for PPC devices. We are looking for a way to lock a license to the hardware. On a PC we'd use read and encode the MAC address, how do we read this or another unique ID from PPC hardware using the compact framework? Any ideas would be gratefully received as its got us stumped!

As you have discovered, the wizard will not do this for you. You need to use
the SqlCeEngine.Upgrade() method. ie something like the following should work
for you:

SqlCeEngine engine = new SqlCeEngine("Data Source=MyDB.sdf;");
engine.Upgrade ("Data Source=MyDB.sdf;encryption mode=platform default;");

This is a new method found in version 3.5 of the System.Data.SqlServerCe.dll
assembly.

Hi Simon,
Thank you, i will try this out. And it seems that will work as a good idea
to do
this programmatically
