    - Build error after upgrade project CF2.0 to CF3.5 Hello, I have upgraded a windows mobile solution to VS2008 and CF3.5. Everything was fine but the build fails with the following error message: Error 132 genasm.exe(1) : error There was an error initializing . Could not load file or assembly 'Microsoft.WindowsCE.Forms, Version=2.0.0.0, Culture=neutral, PublicKeyToken=969db8053d3322ac' or one of its dependencies. Das System kann die angegebene Datei nicht finden. The assemblies are created anyway and if I copy them to my device the program is running stable. I am using 3rd party assemblies that are referencing explicitely to CF2.0 but at runtime this seems to be no problem. Can anyone tell me if it's possible to ignore or fix that error?

    - The Device ID length Hi, I am using pInvoke of KernelIoControl in the coredll to obtain the unique Device ID. After reading up on the Device ID it appears to be stored in 16 bytes. I have an older PocketPC 2003 (HP iPAQ), and the Device ID is quite short, it looks like this (i changed some of the characters) 0f25213c-1d0f-4109-0900-0050bf2000f Now I am running the code on a newer device (HP iPAQ 214), and the Device ID is a lot longer, it looks like this (i changed some of the characters) 50006f00-6300-6b00-6500-74005000470000004960485042523232306f323433333800 So, I'm wondering, what would be the maximum size in characters the Device ID can be? Would it be 128 characters? Thanks for any info, D Tag: ResultsetView Tag: 88274

    - Ping, HTTP Request, and ActiveSync OpenNET CF Ping function works great to detect whether I can get a label to a network printer to print or not. Used to use the HttpRequest trick but the Ping kinda does two chores at one time - network connectivity and individual network device availability. What I need is someway to figure out whether I'm connected via ActiveSync since this will block the Ping packets and lead me to believe I can't print when in fact I can print. So I need a way to check to make sure i don't have an acive ActiveSync connection before I try to Ping. Anyone know of a good way? I've searched the group archives but hoped there was a way lately.

    - Are IntPtr also potentially unsafe in case of exceptions in .NetCF or Hi, i recently red a blog entry (http://blogs.msdn.com/bclteam/archive/ 2005/03/16/396900.aspx) which stated that the use of IntPtr's holding a reference to unmanaged resources could be dangerous in case of object finalization and exceptions. As I understood it the handle finalizer thread (it seems that there is one and I can not change this) could run the objects finalizer, maybe clean up the unmanaged resources (I do this in finanizers) and make the IntPtr invalid. All this could happen while one is actually in a unmanaged method and could lead to problems. Since I use a lot of P/Invoke calls and do stuff on the unamanged side I looked for solutions. A solution is the use of SafeHandles - unfortunately this class/interface is not available in .Net CF. So can't this problem occur in the compact framework or do I have to use another solution (of which I do not know)? It seems that this issue is critical if one uses P/Invokes in objects that are not kept outside the local scope and in case of exceptions. What do you think about this? Thank you in advance, Tom Tag: ResultsetView Tag: 88255

    - Wcf on PDA Problems Good morning/afternoon, I am using WCF with the generated files from NETCFSVCUTILL to communicate with the PC. Now i have found a few problems which i cant seem to solve and are hoping that you guys could help. 1) To test the speed of the connection i made a while loop and got it to send a to the PC from the PDA. But what i found is that it was only sending 4 messages a sec.. which to me seem slow. I might be wrong. 2) when ever a message is sent to the PC the .net compact frame work throws an System.UriFormatException . There is no Uri's in my code. This is the message i get: System.UriFormatException occurred Message="Invalid URI: The hostname could not be parsed." StackTrace: at System.Uri.CreateThis(String uri, Boolean dontEscape, UriKind uriKind) at System.Uri..ctor(String uriString) at System.Net.WebProxy.CreateProxyUri(String Address) at System.Net.WebProxy..ctor(String Address, Boolean BypassOnLocal) at System.Net.HttpWebRequest.SubmitRequest() at System.Net.HttpWebRequest.finishGetResponse() at System.Net.HttpWebRequest.GetResponse() at System.ServiceModel.Channels.HttpChannelFactory.HttpRequestChannel.HttpChannelRequest.WaitForReply(TimeSpan timeout) at System.ServiceModel.Channels.RequestChannel.Request(Message message, TimeSpan timeout) at System.ServiceModel.Channels.RequestChannel.Request(Message message) at Microsoft.Tools.ServiceModel.CFClientBase`1.getReply(Message msg) at Microsoft.Tools.ServiceModel.CFClientBase`1.Invoke[TREQUEST,TRESPONSE](CFInvokeInfo info, PollRequest request) at TruTest.ExternalCommunication.ClientCode.TrutestCommnicationClient.Poll(PollRequest request) at TruTest.ExternalCommunication.ClientCode.TrutestCommnicationClient.Poll(DeviceInfo address, Int32 itemCountToRemove) at TruTest.ExternalCommunication.Service.SmartDeviceService.PollServer(Object obj) at System.Threading.ThreadPool.WorkItem.doWork(Object o) at System.Threading.Timer.ring() i am using the DNS.resolve ("PPP_PEER") to get the host address im sending the message to. Even enter the IP address of the computer this error gets thrown, but the message to get passed from the PDA to the Computer. I think the channel cinnection is been reset each time the Exception is thrown 3) the computers i am on are using proxy. Now to allow the pda and computers to talk to each other i have to physical turn off the proxy in IE. IF i dont, i geta proxy (407) Access denied, even tho im telling it to bypass for local addresses. well i hope some one can help with these problems. Thanks in advances Tag: ResultsetView Tag: 88253

Looks like another new unit with latest OS having the same problem. Is it normal issue or only applies to specific device like Texlogix Psion?

    - Crash in Remote Performance Monitor when trying to use GC Heap function (.NET CF 3.5) I have a generic WinCE 5.0 system (desktop, shell, etc). When I try to use the Remote Performance Monitor tool that comes with the NETCFv35PowerToys.msi, it crashes when I hit the 'GC Heap' button. To reproduce, I can generate an "out of the box" wizard generated C# app targeting .NET CF 3.5 using VS2008. I change the generated Program.cs file to be: using System; using System.Linq; using System.Collections.Generic; using System.Windows.Forms; using System.IO.Ports; using System.Threading; namespace TestRPMTools // your namespace here... { class Program { static SerialPort m_SerialPort; /// <summary> /// The main entry point for the application. /// </summary> [MTAThread] static void Main() { m_SerialPort = new System.IO.Ports.SerialPort("COM4", 115200, Parity.None, 8, StopBits.One); m_SerialPort.Open(); Application.Run(new Form1()); m_SerialPort.Close(); } } } Now, just run this program on the target (using the RPM tool), and start hitting the GC Heap button. Sometimes it works a few times (close GC Heap window without saving if this works), but after a few times it fails, throwing up a message box with this text: exception code: 0xC0000005 exception address: 0x01d3a39c Reading: 0x00000300 Faulting Module: mscoree3_5.dll Offset: 0x0008a39c Does anyone have a suggestions at all as to how to attack this issue? Is this likely to be a bug in mscoree3_5.dll? Is there something that I need to be sure is in my WinCE nk.bin image? (Right now, .NET CF 3.5 is deployed by VS2008 - it is not built into the nk.bin image. I have pretty up-to-date QFEs in the nk.bin.) Full Disclosure: Also, the above code with the serial port is something that I reduced my program to in order to report this issue. But removing the same code from my larger program where the issue was first discovered doesn't fix the issue, so the above code may be a red herring. The crash may be caused by some unrelated issue.

    - Packaging _setup.xml (for SSL Cert) into WinCE 5.0 CAB using CabWiz? I am attempting to install a SSL Certificate on a WinCE 5.0 mobile device. I have already created the appropriate "_setup.xml" file that contains the SSL Certificate installation information (as shown in several posts/blogs/WinCE32 SDK). Now I am attempting to package _setup.xml (or just it's contents) into a valid WinCE 5.0 CAB file. Using the makecab utility provided in the WinCE32 SDK, as in: "makecab _setup.xml rootcert.cab" does not create a "Valid Windows CE Setup File", as reported by the WinCE device when I attempt to manually install the CAB. Therefore it seems like I must somehow utilize the "cabwiz.exe" program, that also comes with the SDK, to try and package my _setup.xml, but how? I have no "Application" to install so what would I specify in the ".inf" file??? Questions: 1) When running cabwiz.exe (WinCE 5.0 SDK), how do I package my "_setup.xml" using a ".inf" file when there is no application to install? And/Or... 2) How do I determine if "_setup.xml" must be considered as extra information for "_setup.xml", which apparently the file that cabwiz.exe itself creates inside of the new cab file!?? The command-line for cabwiz.exe offers the /prexml or /postxml options when creating a cab file - do I need to use them or do I somehow indicate, within the ".inf" file, that my "_setup.xml" file is input for the cab build? I guess I'm just not sure on how to create the ".inf" file for cabwiz without really having an application to install and then go about the task of indicating to the cab setup, "Oh, by the way, would you mind running this snippet of xml contained in my '_setup.xml' file so the appropriate SSL Cert Info is imported/registered properly?" I really hope I'm not confusing everyone but I could certainly use some clarification on how I can package the SSL Certificate '_setup.xml' (mentioned in several blogs/posts that I've seen for PocketPC and Windows Mobile 5/6) into a valid WinCE 5.0 Cab file that I require for my Symbol/Motorola MC3000 Series WinCE 5.0 mobile device...

    - 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: ResultsetView 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: ResultsetView 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. Anyone got any ideas?? Pete Tag: ResultsetView Tag: 88105

    - 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: ResultsetView Tag: 88093
