    - System.Diagnostics.Process TermWaiter.WaitForTerm(); We are using .Net CF 2.0. We want to start the device clock application using Process.Start and when the clock is closed/exitted, we want to carry out some operations. We have used the following code for the same: private void btnAdjustSystemTime_Click(object sender, EventArgs e) { System.Diagnostics.Process proc = new System.Diagnostics.Process(); proc.StartInfo.FileName = "Clock.exe"; proc.EnableRaisingEvents = true; proc.Exited += new EventHandler(clockProc_Exited); proc.Start(); } void clockProc_Exited(object sender, EventArgs e) { //do something here } Once, while executing the above code got a NullReferenceException with only one line in the StackTrace: TermWaiter.WaitForTerm(); After the exception, the application just shut down. Could not recreate this exception. Can anyone help me to find out the cause for the exception and its solution? Tag: Symbol device Tag: 88115

    - Manage in unmanaged easier or unmanaged in managed I need to use managed and unmanaged code. I have two option, using managed class from native C++ code or using native C++ from managed code. Which is easier? I came across ManWrap tools that is better than /clr switch Have few question, please help 1. Is ManWrap (RegExWrap.dll) tools used only to wrap managed class in native C++ classes instead of wrapping native code for managed class usage. Or both. 2. When i install catwork, what is the difference between ManWrap-vs2005-cli and ManWrap-vs2005? which folder should i install? Tag: Symbol device Tag: 88110

    - VS.NET 2008 bug? How to restore Smart Device project templates? This happened before, I tried everything to solve it, but failed. I reinstalled Windows to solve it. Steps 0) OS : Vista x64 1) Install VS.NET 2008 (with Smart Device Development support) 2) Install Windows Mobile 5.0 SDK (if it is not installed, Korean image for WM 5.0 won't install) 3) Uninstall Windows Mobile 5.0 SDK 4) Now, all the smart device project templates are gone. There's no item in the "Target platform" list. Unsuccessful solutions (I mean, none of these worked) 1) Repair VS.NET 2008 2) Go to Add/Remove features of VS.NET 2008, remove Smart Device support, reboot (still all the compact framework packages are shown in the Control Panel > Add or Remove applications) , go to Add/Remove again, add Smart Device support 3) Manually delete all the comact framework related packages, then reinstall them by add Smart Device support at the Add/Remmove of VS.NET 2008 4)Uninstall VS.NET 2008 then reinstall VS.NET 2008 Is there anyway to restore the Smart Device project templates?

    - drawing directly onto picturebox Hi Im making a signature capture and have been looking at examples, got it working ok but i have a problem im captureing all the points so i can redraw the image at will which i have code for in the paint event of a picture box if i try to redraw the image every time there is a new point in the image then it works but starts to slow down the point taking and the image drawing starts to flicker after the first few points. if i dont refresh the image untill the mouse up event it works flawlessly but it is not very good usability for soneone trying to sign the screen as they have to lift the pen to see there progress i have made an application in a normal win32 app and this code solves my problem Dim oldX As Integer Dim oldY As Integer Private Sub PictureBox1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles PictureBox1.MouseDown oldX = e.X oldY = e.Y End Sub Private Sub PictureBox1_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles PictureBox1.MouseMove If Not e.Button = Windows.Forms.MouseButtons.Left Then Exit Sub Dim g As Graphics = PictureBox1.CreateGraphics g.DrawLine(Pens.Black, oldX, oldY, e.X, e.Y) oldX = e.X oldY = e.Y End Sub but when i try the same in a compact framework app i get a not supported exception.

    - Why doesn't it throw an exception to connect to an unexisting IP? This has been really troubling me, at least for few days. I tried to solve it myself but I finally gave up and am asking for some advice. What I'm trying to do is rather simple. To communicate between PDA and PC via good old TCP socket. Since I dont' have a PocketPC, I used the emulator that came with VS.NET First, I tried like Dim client As TcpClient = Nothing Try client = New TcpClient() client.Connect("my ip address", 7778) Catch ex As Exception MessageBox.Show(ex.Message) End Try MessageBox.Show(client.Client.Connected) The problem was, even though I'd typed a wrong ip, the message box always showed "True". The connection error only occurred when the internet connection itself was unavailable. Second, Dim mySoc As New Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp) mySoc.BeginConnect(New IPEndPoint(IPAddress.Parse("my ip address"), 7778), AddressOf OnConnect, mySoc) End Sub Sub OnConnect(ByVal result As IAsyncResult) Dim mySoc As Socket = CType(result.AsyncState, Socket) mySoc.EndConnect(result) System.Diagnostics.Debug.WriteLine(mySoc.Connected) System.Diagnostics.Debug.WriteLine(mySoc.RemoteEndPoint.ToString()) End Sub This was the same, it always printed "True" even thouth the IP address was wrong. I've tested this on VS.NET 2008 (WM 5.0 Emulator + Mobile Device Center) and VS.NET 2005 (PPC 2003 emulator + ActiveSync), but the results were the same. All I want is simple text-based message exchanging. But I'm stuck at the very basic stage like checking if the message was sent and received. Is there any sample code that I can refer to? Please give me some advice. Thank you a lot. PS ------- The server side code was like Dim myIP As IPAddress = Nothing For Each i As IPAddress In Dns.GetHostAddresses(Dns.GetHostName()) If i.AddressFamily = AddressFamily.InterNetwork Then myIP = i Exit For End If Next If myIP Is Nothing Then MessageBox.Show("Can't get the IP4 address of this computer.") End If MyListener = New TcpListener(myIP, 7778) MyListener.Start() MyListener.BeginAcceptTcpClient(AddressOf OnClient, MyListener) Tag: Symbol device Tag: 88093

    - WebService access issue on GPRS/3G Hi everyone, I'm trying to build an application that retrieves data from a web service using its data connection (GPRS/3G). I'm testing this application on an HTC P3650 running windows mobile 6, with .NET CF SP2. As long as the device is connected through activesync, or with a WiFi connection, it works fine. However, when the device is connecting through its data connection, it throws a WebException. On the other hand, I can access the webservice through GPRS without a problem using IE. I know the operator restricts data access to avoid traffic other than http. The APN and proxy settings (which are used for this connection but not through wifi) are configured correctly, but I don't know if I should do anything else. Any idea would help, Thanks Tag: Symbol device Tag: 88074

    - Dotfuscator disassociates derived class when base class is linked Hi all, I know this is a fairly old post, but I just came across it and wanted to clarify things a bit. The "renamed referenced metadata defined only in input map file" is used by our Incremental Obfuscation feature. This allows you to obfuscate a class using a library that was previously obfuscated but which you no longer have access to reobfuscate (say when working on an update to a deployed application). This setting tells Dotfuscator to apply the renames from the map file to references found in the input assembly, without needing the original assembly in which the type is defined.

    - Deploy .Net CF as Visual Studio does Hello. Every time a debug is performed into a PPC using Visual Studio 2005, the IDE deploys the .Net CF into de device. Is there any way to write a desktop application that does the same thing? What I've been doing is developing a desktop application that uses RAPI.dll in order to copy the .Net CF CAB and then I run the process "\windows\wceload.exe" to install the cab. But I would like to find some code that does this operation in a transparent way for the user... I think that the best approach is the one implemented by Visual Studio. Thanks.

    - UserControl - size problem in designer Hi, I have problem with using my user controls in designer - desingner ignores my default size of my control and allways creates new controls with size 200 x 200 points. Since desinger does not show content of usercontrols in CF, this makes UserControls quite unusable for me... 1) I create new UserControl class called MyUserControl and sets it's size property e.g. 100 x 50 points. (I checked generated method InitializeCompoment and it seems fine, size is set to 100 x 50) 2) I use this control in new Form. When i drag this MyUserControl on the form, this control is created on this form, but it's size is 200 x 200 instead of 100 x 50. When i do the same in full Framework, it works fine... Is there any workabout how to make this work? Thank for any ideas Tag: Symbol device Tag: 88060

    - How to scroll large drawings/large docs? Hi, I have a "document". My doc can be divided to thousends of lines. Every line can be displayed as a drawing, every line has an OnPaint method. How can be displayed this document??? The height of every line is 75. If each line is reperesented by separate controls the program will be very slow, because thousands of controls must be checked every time wether they are on the screen or not (?). If the whole document is reperesented by one control size limitation seems to be exceeded: the height of my "one and only" control should be more than 75000. System.Windows.Forms can not be resized (or not always can be resized) to this height. The limit is 32767. ( My very large control is on a Panel in this case. I don't know the general way to handle large docs. Please help!!! Frankie Tag: Symbol device Tag: 88056

    - System.Drawing.Graphics.DrawImage seems to be not exact... Hey everybody, I've a little nice problem here. I want to scale a bitmap, everything seems to be OK, but... I sliced that Bitmap in nine (9) parts - 4 corners (unscaled) - top and bottom middlepart (only horizontal scaled) - left and right middlepart (only vertical scaled) - middlepart (horizontal and vertical scaled) The 4 corners has a width and height of 5 px, top and bottom middlepart has a width of scaled bitmap - 10px and a height of 5px, left and right middlepart has a width of 5px and a height of the scaled bitmap - 10px. The middlepart has a width and a height of the scaled bitmap - 10px. So, if I want to scale the new bitmap I think smaller than the original on, everythink seems to be OK, but when want to scale it larger, I got some problems with the top, bottom, left and right middlepart. It looks like that the starting postions of the bitmap parts had relocated by its own or evrythink else. Does anybody of your had the some problems or the is problem between my ears? Thanks a lot...

I know that in ActiveSync debug, the wireless is disabled but I can run other syncing to a server over the lan via the ActiveSync just fine but the ping always returns either a 1 or a 1000 which aren't even IPStatus enumerations..... Any idea as to what's happening here? I'm not a network guru by any means..... Is this pinging only applicable to wireless?

    - Round to nearest Multiple? NumericUpDown Question. Sorry, a bit new at this CF. I'm looking for a function that will allow me round the min from a now() function to the nearest 15. So for example if it's 9:31 I would like it to return 30 i've got TimeID set as a string: TimeId = FormatDateTime(Now(), DateFormat.ShortTime) which is working fine. and using mid or right am able to get the min separated, but the rounding functions seem to just round to whole numbers. I'd be fine with a floor or ceiling command too, so that 9:31 would return either 30 or 45. I'm using a numericupdown to get the user of the form to input time in increments of 15min. And I guess since I'm on the topic is there anyway to make a NumericUpDown control flip? Using my original example. if I'm at 45 and press up I'd like it to revert back to 00. thanks in advance Tag: Symbol device Tag: 87998

Do you know about a good sync for folders ? I saw plenty of it, but i have no time to compare myself, and suppose somebody have allready done this. in an perfect world, it would be open source, so i can maintain myself and have no problem with closed third part.

    - Calling a managed (C#) DLL from unmanaged (C++) code in Windows CE Hi folks, I know that what I want to achieve works in the "big" framework but I also read (on the blog of the developer group of the compact framework itself !) that it should work on Windows CE devices, too. The only problem: up to now I found no explanation or example, *how* it can be achieved to call a managed DLL (CF 2.0) from an unmanaged EXE (eVC 4) on a Windows CE device (Mobile 2003 or Windows CE 5.0). I've already gone most of the way by following some examples for the "big" framework - the only (?) problem left is the registration of the managed DLL on the device so that the EXE cannot find the DLL and its exported methods. Any idea how to register the DLL on the device or how else the DLL could be loaded? Any help or links to tutorials, posts or examples are welcome! TIA, Roland Tag: Symbol device Tag: 87983

    - Application gone after power on I'm having a strange and almost undebuggable program. During my development, my PDA (a Socket SoMo, and previously an HP) is generally sitting in the cradle and it's powered through the night, so when I come back in the morning the application is still running and everything is fine. However, our sales people take out the PDAs now and the product is beginning to sell. Customers and salesfolk are finding that occasionally (once every 50 times or so) when the PDA is powered down, they power it up and find that the application is just not there. No exception or anything. It's just gone. Since the application disables the taskbar and it starts up automatically, this generally means they are sitting at the today screen and can't do anything. As a temporary fix, I will write a secondary application that keeps checking every 5 seconds (or on power up) that the primary application is running and restarts it if it isn't.. but does anyone know how I can try to track this problem, or if it has been seen before. Any help would be appreciated. Taha Tag: Symbol device Tag: 87962

    - Hooking the power button Hi. There are so many strange things that happen when my iPaq is "off" (stand by mode). My application is sometimes logging activity at 00:00 for several seconds. Sometimes it is waked up and keep logging activity for several hours. Lots of strange things. I must avoid this and detect when the system is in stand by and when it is really awake. Any ideas? I thought of the following, and be happy to get your comments: 1. Check the battery drain... I guess it suppose to be really low when we are in stand by even though there's this phantom wakeup. 2. Hook all messages and intercept the power button. I saw an application doing that, but have no idea how to perform it on c#. As far as I remember, the "journalrecordproc" is obslete since somewhere in the 90's (95?). 3. look for a pixel on screen to decide? I wonder if I'll still get the answer from the image memory and there will be no difference at all if I'm awake or some kind of zombie. 4. Pray that future versions will have only 3 modes: on, off and real standby... and wait for these versions... :) Thanks Empi. Tag: Symbol device Tag: 87960

    - Recieve RAW/binary SMS WM6, C#, CF3.5? Hi! Is there any way to intercept incoming SMS'es from a specific number, and read the body as a sequence of bytes/RAW data? I have tried using a MessageInterceptor as described in http://msdn2.microsoft.com/en-us/library/bb932385.aspx but the Body in the recieved messages simply contains a text that tells that the message cannot be viewed. "Innholdet i denne meldingen kan ikke vises" I know that the SMS message, which comes from a server, is binary, i.e not Unicode, and I know how to decode it - I just need to get access to the raw content.

I've also tried to execute CGACUTIL.EXE from a command shell, and it also do nothing - immediatelly the next prompt is shown, nothing displayed. Executing CGACUTIL on the same target, with CE5.0 on it, opens a window displaying "ver=2.0.7045". What can cause this behavior? Thanks Tag: Symbol device Tag: 87958

    - draw partial last item with OpenNETCF.Windows.Forms.ListBox2 Posted this in the OpenNETCF community but didn't get any response so thought I would try here to see if anyone knows. I'm using the ListBox2 for an ownerdrawn list and placing an image and text in the items. The problem I'm running into is if the ListBox2.Height isn't divisible by ItemHeight perfectly then the last item in the list doesn't show and its just a large white box. It seems that NOINTEGRALHEIGHT isn't available on the ListBox2 or I'm not sure how to use it. I would just like the last ListBox2 item visible on the control to draw even if only 3/4 of it is visible. Thanks for any insight into this issue vince Tag: Symbol device Tag: 87956

    - Is there any equivalent of TimeZoneInfo.SupportsDaylightSavingTime in Hi, I am using Win CE 4.2 with .NET CF 3.5. I need to know if my current time zone support Daylight Saving time. .NET 3.5 full framework has TimezoneInfo.SupportsDaylightSavingTime which is not available in Compact Framework. I have a form in my application where user sets date & time. I am pinvoking to SetLocalTime. When ever AutoDST (Automatically adjust clock for daylight saving) check box is not checked under control panel Date/Time, Sytem.DateTime.Now is off by 1 hours while staying DST start/stop date which is expected behavior. I can set AutoDST check using setting registry key but every Timezone does not observes DST so I can't use this solution generically. If I know that the current time zone is observing DST and new date is in range of DST Start/Stop date, I can add 1 hour. Any help would be appreciated.

    - Mysterious behaviour with UserControl and DocumentList during desi I wrote a simple control derived from UserControl which draws a diagonal line. When I drag this control to a form, the control is displayed, the diagonal line is shown in the form designer. When I add a second form to this solution and put a DocumentList control on that second form, the UserControl on the first form doesn't show the line any more during design time. All design time behaviour is gone. Removing the DocumentList control from the second form, all works well. What am I missing? Tag: Symbol device Tag: 87951

    - Memoryleak - garbage collector / WinCe 5.0 / CF 2.0 Hello, IÂ´m programming a C# application on Windows CE 5.0 and CF 2.0. This application should run permanently (24h/7days). I realized that the garbage collector (gc) does not free all the allocated memory. Thus after a while (a few days) an OutOfMemory-exception occurs. I wrote a small test application: In a function I created a form (Form frm = new Form();) which is shown by ShowDialog(). I figured out that after closing this form and leaving the function, some memory fragments wonÂ´t be freed by the gc (>= 4KB). This behavior occurs when member variables (lists, bitmaps,...) are declared in this created form. If I declare this member variables within a function (stack) the memory will be totally freed. As I can see there is a bug in Visual Studio 2005. The object â??componentsâ?? is created, but never used by the designer. The overridden dispose-function in the designer.cs frees all the objects in the componets-object but â?? as I said â?? this object is never beeing used. I customized all overrides of dispose() in the designer.cs: /// <summary> /// Clean up any resources being used. /// </summary> /// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param> protected override void Dispose(bool disposing) { if (disposing && this.Controls != null) { this.components = new System.ComponentModel.Container(); foreach (Control o in this.Controls) components.Add(o); components.Dispose(); } base.Dispose(disposing); } Now, most of the memory is freed but periodically there still remain some fragments in the memory (>=4KB up to 64KB (?)). I also noticed that running this application on a desktop pc with the â??bigâ?? :NET framework â?? no memoryloak persists! Has anyone noticed the same behaviour and/or found a solution for it? Does anyone have experience with applications running round the clock on Windows CE / CF 2.0? Are there bugs in the gc on compact framework? Thanks for your help, best regards Chris Tag: Symbol device Tag: 87941

You want to look into the Resource Coordination Sample that comes with the
Symbol SMDK. If memory servs you are interested in the trigger_Stage2Notify
event. At least that i what I thing I am using to captude the same key on
an MC50 device.
