    - ImageList & Toolbar crashes Hi, I just made a simple smartdeviceapplication with a toolbar, consisting of a zoom in button and a zoom out button. That's all. I dragged an ImageList to the Form and add the images I created to the ImageList. Then I dragged a toolbar control to the Form and added the imageList to the Toolbar (That's how it's explained in the book .Net CF Core Reference from Microsoft Press). I created 2 buttons for the toolbar, referencing them to index 0 and index 1 of the imageList for the icons. It builds perfectly. But when I run in on my device (HP hx4700): " SmartDeviceApplication3.exe Exception MISC::HandleAr+0x5b ImageCollection::Add+0x2e Form1::InitializeComponent+0x89 Form1::ctor+0xc Form1::Main+0xa " When I remove the connection between the imagelist and the toolbar it works (but offcourse the buttons of the toolbars don't have icons). I Tried both .gif and .bmp but that shouldn't matter normally What could the problem be? Thx! Tag: How to automatically connect through VPN Tag: 58639

    - How to build different interfaces I need, according to the user's own settings and PDA knowing to build different interfaces, that is, a experienced user can see forms with tabs but a user with no experience in PDA using, would see the application with very simple forms, for example with big buttons and so on. Then, what is the best approach to achieve this goal of different interfaces? Add controls at runtime (tabs for the advanced user and buttons for the newbie user) or have different built forms and show/hide them depending on the user? I've not tried but second approach seems to be more effective and faster I understand. And as far as I'm concerned, adding controls at runtime can be a tedious task when many controls have to be placed I think and it's more difficult to develop. Any idea or similar experience will be greatly appreciated. Thanks very much in advance. Tag: How to automatically connect through VPN Tag: 58636

    - What .cab file for Windows Mobile 2003 SE is needed? When implementing the CF solution I've build using CF and OpenNETCF in my iPAQ (Windows Mobile 2003), the following .cab file is copied everytime: OpenNETCF.SDF.ppc3.armv4.cab Now, I must tell some users with Windows Mobile 2003 SE software to install OpenNETCF's SDF. Do they need the same .cab file for this different operating system? I understand that by clicking this .cab file from PPC, Smart Device Framework should be installed for this users. Thanks in advance. Tag: How to automatically connect through VPN Tag: 58633

    - SQL Server CE vs. DataTable Is there any benefit of using SQL Server CE for data storage rather than simply using a dataset? I'm simply getting some data from a SQL Server and will be using this data to verify data that will be scanned with the wireless scanner. I'm thinking that since I do not care if the data is lost if the program is terminated, then I do not need to keep it in SQL Server CE and can easily use a dataset. Is this an OK way of doing this?

    - incoming call not displayed when application running in a smartphone Hi, I've struggling a few days with a bizarr situation. I've a cf smartphone application, that stablish a tcp connection trough a GPRS connection with a TCP Server. When the application is running if an incomming call is received is not displayed in the smartphone, and the caller is receiving the calling tone. I do not know what is wrong ? What i can do to avoid missing the incoming calls ? Some info related to the implementation: 1) TCP implementation using Async Sockets (BeginConnect, BeginReceive, BeginSend etc) 2) All the UI calls ( basically some textboxs) are updated using a ControlInvoker class called from the callback methods. 3) Events are received each 3 seconds, server sends a packet each 3 seconds, and the result is displayed in a few textboxs. 4) The connection is stablished when application is started and is closed when the application is terminated. Advices will be much appreciated Thanks Tiago Tag: How to automatically connect through VPN Tag: 58626

    - Problem with Memory Leak I think and PictureBox I'm using CF 1.1 and am using a picturebox control to implement virtual scrolling. That is, when the person presses the arrows, I replace the Image in the control. I've got 20 or so images I swap in and out with code like the following: Rectangle srcRect = pageLetArray[currentRow, currentCol].localRectangle; Image newImage = Crop(fullYPImage, destRect, srcRect); pb.Image = newImage; After pressing the up and down about 10 or 15 times, I get an out of memory error. I'm thinking the gc should take care of this when I do the pb.Image = newImage but it doesn't seem to be doing it quickly enough. thanks, Peter Kellner http://peterkellner.net Tag: How to automatically connect through VPN Tag: 58625

    - Compat Framework updates. I have found distributable updates for CF .NET, but I have not found a compatible update for Visual Studio - so while my development PDAs have CF .NET SP3 installed, my version of Visual Studio tells me there is an incompatibility between the version of CF it is using and the one installed on the PDAs. Is there such an update for Visual Studio .NET 2003? If so, I'd be grateful for a link to is, as I have not yet found it. TIA Steve Tag: How to automatically connect through VPN Tag: 58619

    - System.MissingMethodException is driving me crazy Hi I have a VB.NET Pocket PC application that I am developing, and have been encountering this error inconsistently. The solution compiles yet when I try to run (via debugging on the device), sometimes I can step into the method LoadForm, but most of the time it comes up with the exception System.MissingMethodException Public Sub New() MyBase.New() InitializeComponent() LoadForm() End Sub Public Sub LoadForm() 'My form loading code in here End Sub This is driving me crazy, I have spent hours trawling through the net trying to find a solution, but nothing works consistently. Sometimes if I rename the method LoadForm then it will run a few times but then once it encounters an exception once, it will not run again. If anyone has any advice or solution, it would be hugely appreciated. Tag: How to automatically connect through VPN Tag: 58614

    - Is SSL Enough? Hi, All : I have a Pocket PC appl and the appl calls a web service by sending XML data. About securing the data, is it enough if I implement SSL on my web server. I did a search and found that everybody was talking about encrypt the xml data and then send to web service and decrypt the data on the web server side. Are there any reason we have to write our own encryption? I thought SSL is enough or is there any limit for .Net CF? Thanks a lot Tag: How to automatically connect through VPN Tag: 58608

    - DeviceID is a bit long I've noticed that the ID you get with KernelIoControl(IOCTL_HAL_GET_DEVICEID . . .) is a big long. Nothing earth shattering in that news I know. I just wonder when using it for licensing if it is a bit long to expect a customer to type it into a web page along with credit card numbers and so forth. I don't feel secure enough with the Handango method of using the Owner ID. So I've thought about some alternatives, including: A shorter "activation code" that checks the internet for status through a web service. A shorter hash of the DeviceID that can be used to generate a license code. Any ideas? Nathan Tag: How to automatically connect through VPN Tag: 58601

    - Frustration with simple walkthrough I am trying to work my way through this apparently simple walkthrough form Microsoft:- http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vbcon/html/vbwlkwalkthroughaccessingxmldata.asp About half-way through it gives the following instruction:- To add the code to create a new dataset that will receive the XML data 1.. With Form1.vb (VB users) or Form1.cs (C# users) selected in Solution Explorer, click the View Code button in the Solution Explorer toolbar. 2.. In the declarations area, declare a new dataset named authors: ' Visual Basic Dim dsAuthors As New DataSet("authors") // C# DataSet dsAuthors = new DataSet("authors");I am trying to do this as c#, and I have been unable to find out where the 'declaration area' is supposed to be. My web searches have not turned up any sort of defintion for this.I did find this, which looks helpful:-http://www.dotnetmonster.com/Uwe/Forum.aspx/dotnet-csharp/39486/Declaration-AreaThe questioner is clearly doing the same walk-through I am doing and has encountered the same problem ... but the responses that helped him have not helped me.

    - Bad Request (Invalid HostName) Hi! I have a website at "http://domainXPTO.net" and I'm triying to access the website in a C#.NET method running in my PDA. I can access the WebService page in "http://domainXPTO.net/service.asmx" several times with direct HTTP calls, following one AND ONLY ONE sucessfull call to any WebMethod. After that, nothing works! All other direct HTTP calls or WebMethod calls return: "Bad Request (Invalid HostName)" I replicated the website environment in my local PC (both IIS website and SQL Server database) and everything works fine. When I deploy it to production in JodoHost... BUMM! I'll try to explain my self by sending the PDA C# code... Heres the C# code -------------------------------------------------------- 01. const string WEB_SERVICE_URL 02. = "http://domainXPTO.net/service.asmx"; 03. public static void Main(string[] args) { 04. try { 05. WebCentral.Service wc = new WebCentral.Service(); 06. wc.Url = WEB_SERVICE_URL; 07. string html; 08. html = Apl.Utils.Net.GetHtml(WEB_SERVICE_URL); 09. html = Apl.Utils.Net.GetHtml(WEB_SERVICE_URL); 10. WebCentral.PdaInfo pi = wc.GetPdaInfo("1234567890"); 11. html = Apl.Utils.Net.GetHtml(WEB_SERVICE_URL); 12. html = Apl.Utils.Net.GetHtml(WEB_SERVICE_URL); 13. } catch (System.Net.WebException ex) { 14. string html2 = Apl.Utils.Net.GetHtml 15. ((HttpWebResponse)ex.Response); 16. } 17. } The code never reaches line 12. The imediate HTTP call (line 11) after the sucessfull WebMethod call (line 10) throws a WebException with the server error 400: Bad Request (Invalid HostName). If I try executing two exact WebMethods in a row, the first is sucessfull and the second blows with the same "(Invalid HostName)". It seems like the server gets busy with the first WebMethod call and then redirects all of the other HTTP calls (text and soap) to a diferent server with another name. Because the request's HTTP header doesn't have the second server "HostName" the HTTP request is denied. Just a wild guess :) Any clues? Just some other infos: 1. If I try this code in a Windows Forms .NET application it seems to works fine, only the PDA version doesn't work. 2. In my local development environment the two versions work fine.

    - Xml Errors In Data Panel Viewer In viewing an Xml file created by DataSet.WriteXml() I get the following error-- "The active schema does not support the element" The error appears as a swiggly red underline with the above text when you place the cursor over it. It appears for every element. The file loads ok into a another DataSet object but you cannot view the data in the Data panel the Xml viewer of Vs2003. The data is corrupted in that view. You can see it in the Xml viewer panel (with the swiggly red underlines). The top of the Xml data file looks like this-- <?xml version="1.0" standalone="yes"?> <NewDataSet xmlns="http://tempuri.org/XMLSchema.xsd"> <InstrumentDescriptor> <DeviceName>Rheodyne Switching Valve</DeviceName> â?¦ If you remove the line <NewDataSet xmlns="http://tempuri.org/XMLSchema.xsd"> and its corresponding closing line the swiggly red lines go away BUT the DataSet will no longer load the file properly. Rows are missing. If I manually edit the line <NewDataSet xmlns="http://tempuri.org/XMLSchema.xsd"> and change the XMLSchema.xsd to the actually schema file the errors go away but again a DataSet object will not properly load the Xml file. There is corruption. The top of the schema file that is used to create this DataSet object looks like this-- <?xml version="1.0" encoding="utf-8" ?> <xs:schema targetNamespace="http://tempuri.org/XMLSchema.xsd" elementFormDefault="qualified" xmlns="http://tempuri.org/XMLSchema.xsd" xmlns:mstns="http://tempuri.org/XMLSchema.xsd" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:msdata="urn:schemas-microsoft-com:xml-msdata"> <xs:element name="UserConfiguration"> â?¦ To verify the situation (since I did not create the App that generates the Xml file from an internal DataSet) I loaded the file as originally presented (with the XMLSchema.xsd) then saved it to a new file. The new file has exactly the same heading information. In other words it comes out of the DataSet this way. Any help would be appreciated since I need to be able to view and edit the data in the Xml file using the Vs2003 Data panel. All this takes place in a WinCE project.

I've just taken delivery of an Imate Jasjar/HTC Universal I have managed to install the Visual Studio 2005 Beta 2 GPS sample/(Windows Mobile 5 SDK).

I set my GPS Program port to GPD1 with a hardware port of COM4 (having first partnered with bluetooth GPS) However when I run the GPS sample, it connects returns a date and time but doesn't give a lat/long.

    - DataView.RowFilter bug? Hi all, I have really trouble with my WinCE application. My app is constructed as follow: The mainform opens a second form as modal dialog [form2.ShowModelDialog()] In form2 is a datagrid. The datasource for this grid is a static dataset from a consts class. To filter rows I set the rowfilter from the DefaultView of appropriate table.

But when I close the modal dialog and reopen (new instance of form2 !) I get following exception: Eine nicht behandelte Ausnahme des Typs 'System.ObjectDisposedException' ist in System.Windows.Forms.dll aufgetreten. What the hell is going on?!?!

    - Have LocalAlloc and LocalFree to be declared as shared methods? Hi all, I'm using a ping class for a couple of months. Everything worked fine. All class methods were declared as shared (static in c#) methods. Now I want to make the class threadsafe, so I started to remove the shared methods and made a 'normal' class of it, which has to be instantiated. The class is using a couple of API calls, under which LocalAlloc and LocalFree. These 2 functions do only work if declared as shared methods. Why? <System.Runtime.InteropServices.DllImport("coredll")> _ Private Shared Function LocalAlloc(ByVal Flags As Integer, ByVal size As Integer) As System.IntPtr End Function <System.Runtime.InteropServices.DllImport("coredll")> _ Private Shared Function LocalFree(ByVal pMem As System.IntPtr) As System.IntPtr End Function What do I have to change? Would my class be threadsafe if LocalAlloc and LocalFree are declared as shared methods? Keep in mind, my aim is a threadsafe class. I want to avoind using sync objects...

CF and Studio I am looking for C# tutorials that are good for complete novices - I mean no experience of Visual Studio, never mind no experience of C# or .Net Can you recommend any good places to start? A general web search is quite overwhelming, so I would appreciate if anyone here could help steer me towards some of the most appropriate resources.

    - Network Development on CF 1.0 Hi, everyone. =) I'm looking for examples, samples, etc. pertaining to networking between PPC and desktops. The plan is to transfer commands and information over a network between the device and PC to remote control a PC application. Much of the server side and client side code I can figure out on my own, the biggest thing I need help with is creating the connection, building and transmitting the packets, and decoding the packets on the destination. I don't have a book budget right now, so I'm trying to find as much information as I can online. Thanks in advance. =) Flynn --------------- If we can't corrupt the youth of today, the adults of tomorrow won't be any fun. Tag: How to automatically connect through VPN Tag: 58535

    - Setting time in .net 2.0 I am trying to set the time programmatically on my PPC device and as expected, the time zone information is not refreshed. However, when I run the code that forced the refresh in 1.1, it is giving a null reference error. Has anyone run into this and know how to resolve it?

    - Deploying PPC 2000, 2002, and 2003 .NET App I was wondering if anyone can direct me on where to go for information on or how to create a single msi to install a .NET CF 1.0 app on all three PPC 2k, 2k2, and 2k3 platforms. I am using Visual Studio .NET 2003 and have managed to make an installer that copies the cab files and then executes the CeAppMgr.exe, but every time I try and install to a PPC 2k3 device, it says the installtion failed on the device. Any suggestions or directions to information would be helpful. I'm currently trying to create the installation file in Visual Studio 2k5 Beta 2, but if at all possible, I'd prefer to use something that's "relases" status.

    - unhandled exception I wrote an application for our iPaq to do in the field inventory work. Like many projects around here as soon as it was completed people forgot that they needed it.

Hello everyone!

One of my clients wants to use VPN-connections on their handhelds. We
have tried this and it seems to work fine except for one thing: When
using our application, that is written using .NET CF, the VPN does not
automatically connect, but if we use Internet Explorer, Terminal
Services Client or any other networking application, the VPN-connection
is automatically connected. This means that whenever the handheld is
suspended the user has to connect the VPN-connection manually in order
for our application to find the server. How can I make our application
connect automatically?

Regards,
Anders

Is there nobody out there who uses VPN-connected devices together with
your own socket-connected .NET CF-programs?
