    - Any good 3rd party mobile grids out there? I'm curious if anyone has any strong recommendations for a 3rd party grid. I've read on the ComponentOne Flexgrid for mobile devices and it appears to have more than it's fair share of issues. Any others??

    - 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: Using C++ code developed in WinCE 4 in C# application in VS2003 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: Using C++ code developed in WinCE 4 in C# application in VS2003 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!

    - Setup.dll and CEAppMgr If I want to use a setup.dll to customize my installation, do I need to use the process described in http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnppcgen/html/netcfdeployment.asp? I.e., if I'm using setup.dll, is it true that I can't do it deploying the CAB directly to the device, but rather that I must use CEAppMgr?

    - 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?

    - 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: Using C++ code developed in WinCE 4 in C# application in VS2003 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: Using C++ code developed in WinCE 4 in C# application in VS2003 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: Using C++ code developed in WinCE 4 in C# application in VS2003 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: Using C++ code developed in WinCE 4 in C# application in VS2003 Tag: 64195

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: Using C++ code developed in WinCE 4 in C# application in VS2003 Tag: 64104

    - 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?

    - .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: Using C++ code developed in WinCE 4 in C# application in VS2003 Tag: 64081

    - Memory leak with container controls Hello, I have a form with a button, the button opens another form using showdialog. The second form contains a panel which contains a tabcontrol wich contains on each of its tabs a bunch of labels. After closing the second form, I call dispose and even ask for garbage collection, but even this way the memory is not freed. This is the code that opens the form: Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim formu As New Form2 formu.ShowDialog() formu.Dispose() formu = Nothing GC.Collect() End Sub I don't know if it's a known bug and if there's any solution to this problem. I tried upgrading from compact framework 1 sp3 to 2.0, but it's still the same. Thanks a lot JoaquÃn Raya Tag: Using C++ code developed in WinCE 4 in C# application in VS2003 Tag: 64066

    - How to get a WM5 device's O/S Version in a call without using RAPI? Hi all, Currently, I have an app compiled in VS2003 that I want to also be able to run on WM5 devices for my customers. My custom installer uses MSI and RAPI calls for installation of my app. Currently, before I transfer the correct CAB for the device, I do a RAPI call to get the device's operating system version. This app has been designed for PPC 2002 and WM2003 including Second Edition, and therefore you need to know which CAB to install. I have found my app runs well on a WM5 device as I have it running on my Dell Axim X51v but I need to be able to know the device's operating system version for WM5 devices so I know what CAB version to download. The problem I am having is that some Pocket PC Phone Edition with WM5 , like the i-mate JasJar, seem to make RAPI unavailable. Does anyone have another idea / method of determining the i-mate JasJar's o/s version without using RAPI? BTW, this is to be my last patch update of my app under VS2003 and want it to deploy it onto WM5 devices since my customers are wanting this requirement. The next release of my app, after this patch update, will be a major update and will be compiled with VS2005 and use CF2, but for the interim period, I need to be able to use my current VS2003 compiled code on all WM5 devices.

    - WebBrowser control - CF 2, C#. Full screen? I added a web browser control into my project yesterday. I want to use it to present Flash content, full-screen. It seems that no matter what settings I choose, the WebBrowser will not ever let the Flash movie fill the PDA screen. The movie was published at 240x320 resolution. The HTML says it is that size. I've tried publishing it larger, and manually editing the HTML to make the Flash file appear larger. In the HTML I added this css to make the html file margin free <style type="text/css">  </style> The WebBrowser is set to full screen, but I have also tested it larger than full screen. I have experimented with the various publishing options available in Flash. I've tried numerous other things (scale settings for instance) without success. Nothing I have tried will get the Flash movie to fill the screen. Is this a known bug? Or am I doing something wrong? Anyone know of a workaround?

    - Hosting Native Windows Control on CE .Net I have went through the following article by Peter Foot Microsoft Embedded MVP In The Hand Ltd Title : Hosting a Native Windows Control within a Microsoft=AE .NET Compact Framework Forms Control URL : http://msdn.microsoft.com/library/default.asp?url=3D/library/en-us/dnnetcom= p/html/HostingANativeWindowsControl.asp Great article since I have been scouring the Internet on how to port Windows COM / ActiveX control to be used in CF .Net platform and this is the only usefull article I have found. The article also show how to do this using OpenNetCF which save time since I don't have to implement a lot of thing myself. However there is one critical part that I cannot understand. Regarding how window message passing is used to implement/wrap property, method and event. For instance, let say I have a native window ATL control with the following interface source code: __interface IAtlTest : public IDispatch { [id(1), helpstring("method GetVersion")] HRESULT GetVersion([out,retval] BSTR* version); [propget, id(2), helpstring("property Author")] HRESULT Author([out, retval] BSTR* pVal); [propput, id(2), helpstring("property Author")] HRESULT Author([in] BSTR newVal); }; In order to access this method and property I need to create 3 method that send message using Win32Window.SendMessage(handle, message_id, wParam, lParam) My question is 1=2E What should mesage_id parameter be? Can I find it somewhere in my atl control source code? 2=2E If I have an ATL control dll file without source code. Is there a way to know this message_id without any documentation from the dll developer? Your feedback are appreciated.

    - Reading colors from .config file I want to have an entry like this in my .exe.config file: <AppSettings> <add key="EmergencyFormColor" value="Color.Red" /> <add key="MainFormColor" value="Color.AliceBlue" /> </AppSettings> I'm able to read this parameters from code with OpenNETCF.Configuration namespace but I obtain string datatype. In order to assign the BackColor property of the form, I need the type to be System.Drawing.Color but I can't find a way to convert the value! Another option: Instead of Color.Red, write 12,12,12, that is, RGB values. But by code I would have to split the string in three parts, and convert the values into integer in order to use Color.FromARGB(int R, int G, int B). Do you see any direct converion or way I can do this easily? I want the user to be able to change application's color easily. Thanks.

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.

Thanks in advance
Victor
