    - Multi-User TCP chat application Hi, I am creating a multi-user tcp chat application following the example instruction in msdn http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnadvnet/html/vbnet08282001.asp however, on the client side (Pocket PC), it will only run for the first time, but once connected to the chat server and close the application, i cannot start the application again for a period of time until i get an exception (ObjectDisposeException). I guess this is due to the DoRead thread socket is still open? cos it then ask for MarkAsDisconnected for the txtSend & btnSend which therefore throw the exception (i guess?) but i have already closed the socket using: mobjClient.GetStream.Close() & mobjClient.Close() Any ideas? any help would be good... Many thanks in advance! Here are my code: ------------------------------------------------------- Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Try mobjClient = New TcpClient("localhost", 5000) DisplayText("Connected to host" & vbCrLf) mobjClient.GetStream.BeginRead(marData, 0, 1024, AddressOf DoRead, Nothing) Catch ex As Exception MsgBox(ex.Message) End Try End Sub Private Sub btnSend_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSend.Click Send(txtSend.Text) txtSend.Text = "" End Sub Private Sub Send(ByVal t As String) Dim w As New IO.StreamWriter(mobjClient.GetStream) w.Write(t & vbCr) w.Flush() End Sub Private Sub DoRead(ByVal ar As IAsyncResult) Dim intCount As Integer Try intCount = mobjClient.GetStream.EndRead(ar) If intCount < 1 Then MarkAsDisconnected() Exit Sub End If BuildString(marData, 0, intCount) mobjClient.GetStream.BeginRead(marData, 0, 1024, AddressOf DoRead, Nothing) Catch ex As Exception MarkAsDisconnected() End Try End Sub Private Sub BuildString(ByVal Bytes() As Byte, ByVal offset As Integer, ByVal count As Integer) Dim intIndex As Integer For intIndex = offset To offset + count - 1 If Bytes(intIndex) = 10 Then mobjText.Append(vbLf) '''Dim params() As Object = {mobjText.ToString} '''Me.Invoke(New DisplayInvoker(AddressOf Me.DisplayText), params) DisplayText(mobjText.ToString) mobjText = New StringBuilder Else mobjText.Append(ChrW(Bytes(intIndex))) End If Next End Sub Private Sub MarkAsDisconnected() txtSend.ReadOnly = True btnSend.Enabled = False End Sub Private Sub DisplayText(ByVal t As String) Dim liv As New ListViewItem(New String() {t}) ListView1.Items.Add(liv) End Sub Private Sub Form1_Closing(ByVal sender As Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles MyBase.Closing mobjClient.GetStream.Close() mobjClient.Close() End Sub ------------------------------------------------------- Tag: CF2.0 book recommendations?

    - Using C++ code developed in WinCE 4 in C# application in VS2003 Hi I have a need to incorporate C++ code developed in WinCE 4 (LCD driver for SED1520) in C# application developed in VS2003. This is new to me and am not quite sure how to approach. I have read information in MSDN and it seems that I need to build the driver as an DLL and use PInvoke in C# to call low level function in the C++ code. But again all references I read so far refer to C++ developed in Visual C++ not in WinCE 4. I would appreciate if anyone who have done this or have any suggestion to give me some advice.

    - sharing a class between CF and non-CF projects I want to define my domain object classes (Customers, Orders, etc.) in an assembly to use in Compact Framework as well as ASP.NET and Windows Forms components. I don't want to duplicate validation logic, property definitions, etc. I'm considering using XPO (ORM) or something similar, and there are different references I need to use if I'm in one world or the other. Has anyone out there successfully straddled the CF and non-CF worlds this way? In C++, eVC, etc., you could use pre-compiler directives to include or exclude source files based on pre-compiler constants. Does Visual Studio 2005 have something like this? Is there a sneaky little trick I could use? O Tag: CF2.0 book recommendations? Tag: 64256

    - VS 2005 PocketPC project: no GroupBox control, no BorderStyle property for Panel control... Hi all, I'm starting my first project with .NET for Pocket PC by using Visual Studio 2005 Professional. My first shock: it is no GroupBox control on my Toolbox for the default created Device Application project created by VS. Which reference should I Add to my project to "see" the GroupBox? Or may be it is not available for the PocketPC? Ok, no GroupBox, then the Panel control should do the work. But it is here the second shock: The documentation says it should be a BorderStyle property to make the border solid and visible, but at least it is not available at design time 'cause I can't find it in my Properties... What is wrong with my brand new VS2005? Thanks in advance Sammy Tag: CF2.0 book recommendations? Tag: 64240

    - ListView ItemCheck is always one behind?? VB I am using Visual Studio 2005 (visual basic) and Compact Framework 2.0 I have a ListView that will contain several Items. The ListView has checkboxes enabled. Whenever the user clicks on a checkbox to change it (check or uncheck) I want to indicate how many items are currently checked. This routine below looks correct to me, but each time I check or uncheck the number reported back is always the previous count and not the current count of items that are checked. Private Sub ListView1_ItemCheck(ByVal sender As Object, ByVal e As System.Windows.Forms.ItemCheckEventArgs) Handles ListView1.ItemCheck Dim CheckCount As Integer Dim NItem As ListViewItem CheckCount = 0 For Each NItem In ListView1.Items If NItem.Checked Then CheckCount = CheckCount + 1 end if Next Msgbox("Number of items checked are: " & CheckCount) End Sub Can anybody tell me why the CheckCount is always behind? For example if no items are checked and then I check one item, the checkcount is still zero. When I uncheck that same item then the checkcount is now 1. It is like the state of being checked or unchecked for any item happens after the ItemCheck event in the ListView. I looked for an ItemChecked event but no such event shows. Help!

    - Printing options ( a little OT ) Hi, I need to print from a PPC to a printer , ideally a dot matrix printer ala Epson LX300 , LQ580. I know there is no support for printing in the current environment. I'm deciding in using either PrinterCE ( http://www.fieldsoftware.com/PrinterCE.htm ) or PrintBoy: (http://www.bachmannsoftware.com/pbce.htm) both provides an SDK for dotnet and seems equally good. My main concern is the connectivity, how to connect the above printers that are either serial or parallel to an iPaq? Is bluetooth the way to go? Basically I'm looking for feedback from anybody who had deployed something like this before.

    - Program Memory Low - Select a task to close or increase program memory I've been putting my application(C#, .NET CF) through some stress testing when I encountered this pretty nasty problem. Basically, when the application runs out of memory I get the "Program Memory Low - Select a task to close or increase program memory" dialog window with a list of running tasks that I can close to choose from. My app, however is NOT listed there. So, if I close everything else and my app still needs more memory I keep getting instances of this dialog window with nothing to choose from until eventually the whole system crashes at which point I need to do a restart. So, it looks like I'll have to handle this problem inside my application. The problem is I could not find a way to programatically determine the amount of free memory at a given point of time. I also could not find any event that occurs when there is no more free memory which I could handle inside my app. Does anybody have any idea how I can handle this problem?

    - VS 2005 Cab project doesnt include form localization resource dlls I found a bug in VS 2005. If you choose Localized=true on your form and then make some resx files e.g. Form1.de.resx and change all the strings to German ones as you usually do - when you deploy the project to a pda it works perfectly and creates a de folder on the device with the german resource dll in the folder. However if you make a CAB project and choose the app project to be included, when you build the CAB it does not include any of the localization dlls in it. Does anyone know if this is really a bug or is there a setting somewhere I need to enable? Thanks, indiekiduk www.aspecto-software.com Tag: CF2.0 book recommendations? Tag: 64218

    - Custom Uninstaller and App Manager Hi all, When I deploy my VS2003-compiled app, it installs EXEs to the desktop side and uses the ActiveSync AppMgr to install the CAB to the device. I also control the deployment using an MSI file and have a custom installer and uninstaller on the desktop. After my app is installed, I have found that it can be Removed in two places - i) the Remove button on ActiveSync's Tools -> Add/Remove Programs and, ii) the Remove button for the app on the Add or Remove Programs on the control panel. Removing my app using the Remove button on ActiveSync (AppMgr) works perfectly as it has been setup to call my uninstaller via the AppMgr INI file, and so things get tidied up on the desktop side as well as the device side. However, if I (or one of my customers) decide to remove my app using the Remove button in the Add or Remove Programs on the Control Panel, the removal process fails. I assume at this point the uninstaller has no knowledge that the app was installed on the device via AppMgr and so the removal from the device does not happen. How can I prevent either i) the app from appearing on the Add or Remove Programs list in Control Panel or ii) prevent the Remove button from being operational on the Add or Remove Programs list and give a reminder to use the ActiveSync Remove button instead? I will be interested to know how others have got around this one when using MSI deployment. Regards, Neville Lang Tag: CF2.0 book recommendations? Tag: 64215

    - need to build limited browser as custom shell Hi, I have a pretty straightforward project for Windows CE. It would be a custom shell, launching a restricted browser, which would open up the default home page, allow forward and back buttons, but not let the user type in their own URLs. In other words, users would be forced to stay on the default website and any links from there. I'm deciding how to get started on this. It appears that the IE browser is available as an ActiveX control, but not as managed C# code. I've heard that OpenNetCF has a managed code browser control. Basically, I'm just looking for some direction here before I start down a path. My choices appear to be: 1) C# OpenNetCF 2) C# IE through interop/ActiveX 3) C++/ActiveX native solution I'm not crazy about the idea of interop, which seems like a square peg in a square hole... I don't know much about the OpenNetCF control. I'm an experienced C++ programmer, but I'm developing a taste for C# in a big way. Any advice, information or mistake corrections in my assumptions would be appreaciated. Thanks in advance Tag: CF2.0 book recommendations? Tag: 64207

    - WCELoad - Confirm file replace message I am working with the .Net Compact Framework, Windows CE 4.2 and VS .NET 2003 I have a situation where I need to silently install a cab file on the CE device, I cannot rely on the user pressing any yes/no buttons, so I have created the cab so that there are no read-only files etc. I install the cab by copying it onto the device and then remotely calling wceload.exe, using the OpenNetCF.Desktop.Communication.RAPI class, and giving it command line argument of /noaskdest "test.cab". Every now and then, and I cannot seem to nail the pattern, I receive a "Confirm file replace" message with Yes, Yes to All, No and No to All buttons. If I click Yes to All, I don't receive the message when I attempt to install the cab again, if I click No to All, I do, as you would expect. I have attempted to use /noui, but that doesn't help at all. I have attempted changing the fAskOptions value under the HKLM\Software\Apps\Microsoft Application Installer key, to no avail. I have exported the registry, both before and after an install and compared the two and there nothing out of the ordinary is changed. I have exported the filesystem information, again, before and after an install and compared the two and, again, nothing is out of the ordinary. I would appreciate any ideas as to why this is occurring. Tag: CF2.0 book recommendations? Tag: 64199

    - Architecture Question Hi, I am still fairly new to developing apps for the ppc but I'm working o this app and came across an interesting question. The short story is: the app needs to access about 5,000 data records t be of any use. I have the option of using a webservice to provide th data to the ppc (through some sort of filtering mechanism) or spawnin a separate thread and downloading the data into a SQL CE databas (which takes between 5 and 10 mins) and then providing a filterin mechanism. If I choose the webservice, this obviously requires a constan connection - which apparently from the resources I've seen most of th ppc devices have that built in. That might make this the best option. The only reason I'm considering downloading the data to SQL CE is jus in case the user doesnt have a valid internet connection, the app coul still be utilized. Is this a legitimate concern? Or is the industry standard thinking th devices should always have an internet connection?

    - Problems with Rs232 under Netcf I am using the Rs232 approach outlined in the Mdsn article "Use P/Invoke to Develop a .NET Base Class Library for Serial Device Communications" to connect to an Rs232 device from a WinCe device. I made modifications, some suggested on this forum. It does connect with the device but occassionaly it stops communicating. A simplier App that uses the OpenNetCf Port works reliably. Since I am migrating a fairly large App from desktop to WinCe I would rather not change their code more then necessary. The following are the code snippets that open, write to and read from the Rs232 line. Could you suggest what I might be doing wrong? Note that I did remove the overlap from the desktop approach. hPort = Win32Com.CreateFile("COM1:", 0x80000000|0x40000000, 0, IntPtr.Zero,Win32Com.OPEN_EXISTING,0, IntPtr.Zero); if (Win32Com.WriteFile(hPort, tosend, (uint)writeCount, out sent, ptrUWO)) {writeCount -= (int)sent; } else {if (Marshal.GetLastWin32Error() != Win32Com.ERROR_IO_PENDING) ThrowException("Send failed"); } if (!Win32Com.ReadFile(hPort, buf, 1, out gotbytes, unmanagedOv)) {int x = Marshal.GetLastWin32Error(); throw new CommPortException("IO Error [004]"); } -- John Olbert Tag: CF2.0 book recommendations?

    - Pocket PC App Performance Enhancement We are developing a bulky Pocket PC 2003 Application using .NET CF in VB.NET as a Windows App - The resulting App is very slow when it comes to Loading and Unloading of Forms and Display of GUI elements inside TabPages. Kindly throw some light on the following - 1. Whats the maximum number of Controls that can be added to a Form 2. How to speed up the following - Form.Show() Form.Hide() Form.Close() Form.New() Is any kind of buffering is possible for Show() and Hide() ? We are already not calling Close() function for forms as it bogs down the app. Links on performance optimization for .NET PDA applications would be great! Many Thanks!

    - Scrolling panel - initially displays already scrolled I added a panel to my form - panel1. In that I added 4 more. Each of these has some buttons in it. I set panel1 to autoScroll = true. When I display my form, the panel is already scrolled almost to the bottom. I tried setting panel1.AutoScrollPosition and panel1.AutoScrollPosition.Y but they don;t seem to have any effect. Any suggestions about what I missed? Steve Tag: CF2.0 book recommendations? Tag: 64138

    - CAB file auto-extraction In have a CAB file which contains other CAB files. On a WM2003 device the full CAB file is deployed to a Pocket PC, exploded, then the other CAB files within that CAB file are also exploded (via a third party application). If I deploy that same CAB file to a WM5.0 device, the first CAB is exploded, but the subsequent files are not. Is there anything in the first INF file that I could add to ensure all the other CAB files are also exploded? Thanks Tag: CF2.0 book recommendations? Tag: 64119

    - How to deploy two projects in same solution individually? In VS2003 I've got a Solution that contains two Projects; both projects have separate Output file folders, have different Assembly Names, etc. When I build the CAB file of the solution I update each INF file to specify different paths and application names. However when I deploy both cab files to the Pocket PC, the first installs ok. Then when the second cab file is installed, it says "ApplicationX is already installed. Do you want to reinstall?". Obviously I don't as it will uninstall the first install! Does anyone know how or where I should be specifiying unique application names so both cab files can get installed correctly?

    - Intermittent problem when calling Socket.Available I have an intermittent problem where calling Socket.Available to see if there is any available data results in a SocketException with the message "An operation was attempted on something that is not a socket". Once the socket gets in this state it is no longer usable. This code is shared between a compact framework and desktop version of our app, and I've not experienced this on the desktop version. Has anyone else seen this before and can offer any suggestions as to how to overcome it? I'm thinking of detecting this particular exception and treating the socket as 'invalid', and signaling a disconnection event so the consumer knows the socket connection needs to be re-established, but that seems very kludgy to me. As a secondary question, I am currently taking the approach that I call Socket.Available before calling Socket.Read to ensure I don't have the receive thread entering a blocked state while I wait for data to appear via the socket. I'd love to be able to use a blocking read approach, but my inexperience with inter-thread communications on the CF has encouraged me to go with my current approach. In particular what I'm unsure of is how to fire an event from the socket reading/writing thread but have it run in the context of the thread which is consuming my socket class (which manages the socket thread). I think I'd be able to achieve close to what I want by using another thread who's sole purpose is to monitor the socket thread for events (by using WaitForMultipleObjects, so multiple events can be monitored), but this seems a little convoluted and messy to me. And even then, any delegate being fired from this event monitoring thread would be running in its context rather than the thread which originally created my socket class. What is the best approach to handle this? -- Cheers, David Clegg dclegg@gmail.com http://cc.borland.com/Author.aspx?ID=72299 QualityCentral.

    - Radio button background colour - CF 2, C# I made radio buttons with a coloured background, and placed them on a form that was the same colour. The buttons look great, aside from the white square behind the buttons! The square is the same size as the circle of the radio button. I couldn't find a property that would get rid of the white square. What did I miss? Tested on a WM2003 device (Toshiba E750) My solution was to add a white panel and drop the radio buttons onto that ... so the buttons were the same as the white background.

    - SQL Mobile slower than SQL CE 2.0 Based on what I've read about performance improvements in SQL Mobile, I have started down the road to migrate an application from VS 2003/SQL CE 2 to VS 2005/SQL Mobile. So far, however, I am sorely disappointed with the performance of the new platform. In fact, filling a datatable with one of my queries has proved to take over 10 times as long on the new platform. This is such a big difference that I'm sure I must be doing something wrong. I'll post my code and I would appreciate if anyone has any ideas for me. Dim sSQL$ Dim oCmd As New SqlCeCommand Dim oDA As New SqlCeDataAdapter Dim oDT As New Data.DataTable sSQL = "SELECT Questions.ID AS QID..." Try Dim Conn As Data.SqlServerCe.SqlCeConnection = New Data.SqlServerCe.SqlCeConnection("Data Source=\CF Card\DB\DB1.sdf") oCmd.Connection = Conn oCmd.CommandText = sSQL oDA.SelectCommand = oCmd oDA.Fill(oDT) '(I've also tried the new SqlCeResultSet without much better success: Dim rs As SqlCeResultSet = oCmd.ExecuteResultSet(ResultSetOptions.None) ) Catch ex As Exception Throw New Exception("Error" & vbCrLf & vbCrLf & ex.Message) End Try Thanks Tag: CF2.0 book recommendations?

    - validate controls Hi all, I create custom controls with textboxes on it, that need validation. So I created methods like these... void txtName_Validating(object sender, CancelEventArgs e) { // Name is required if (txtName.Text.Trim() == "") { // simulate ErrorProvider txtName.BackColor = Color.Aqua; // what about an error message? MessageBox.Show("Name is required!"); e.Cancel = true; return; } txtName.BackColor = Color.White; } ... and in the Designer set the "Validating" - event to this method! Now when I use these new custom control I want to make sure, that for example on buttonOk-click all my controls get validated. How can I do this? I found examples with a Validate()-method, but I don't have this method on compact framework! Any workaround? Thanks in advance Daniel Tag: CF2.0 book recommendations? Tag: 64096

    - .NETCF 2.0 app abruptly exits without any exception info I'm seeing a weird problem in a .NETCF 2.0 application running on a HP hw6515 (PPC 2003 SE Smartphone edition). Sometimes, the application suddenly exits without (apparently) an exception occuring. The application itself is moderately heavy (uses a few native DLLs) but usually when a problem occurs in one of the DLLs, I get an exception message. In this case, I get nothing. I'm starting to suspect an issue with the .NETCF runtime. Did anyone see something similar? Unfortunately, the problem seems erratic. My app can run for hours without crashing, and sometimes after a few minutes (without touching the device) it will just ... poof! vanish. Any lead on this? Could this be related to a memory shortage on the device? Tag: CF2.0 book recommendations? Tag: 64081

afaik, there aren't any. A couple of us proposed one to MSPress but they
seem to not think it is needed.

If you own a v1 book or are familiar with v1, there are some links to what
is new here (near the bottom):
