    - Emulator 2.0 error opening images with mapped COM port I am successully using the WM 5.0 MSF emulator to run TomTom5 (much larger picture than my PDA...). A bit slow and erratic to start (need 5 or 5 tries to start the image), but once started, it works. My question: since everyone says that 2.0 is faster and more stable, I installed it; problem is, it cannot open my images with the COM port once mapped (it opens fresh images with no mapped COM port) - same problem on my laptop, and 2 PCs. Problem both with bluetooth serial port and a wired GPS. Error #1: "Unable to open serial port "COM6" LastError=Access denied." Error #2: "The device emulator coud not start, possiblyif incorrect statup parameters" Any suggestion I would appreciate any help.

I tried to re-install ActiveSync 4.0, but still did not fix it. I tried to install 4.2, but sometimes, it does not work for my X51 which is WM5.0. I think there must be some registry for it, but, don't know where it is. Any input are appreciated. Thanks. Tag: .NET Compact Framework serial port error on power off/on Smart Device Development

    - No automatic resizing on devices with vga display? I developed an application with .NET 2.0 CF (Sp2) and everything works fine on a windows mobile 5 device with a common display size. But on a wm5 device with a vga display (480x640), the size of the buttons and other components is not automatically resized. This leads that the whole application on a device with the bigger display size looks like that everything is moved to the upper right corner. Unfortunately, the size of the fonts is changed - e.g. the text in the buttons is too big for the button. The whole application can't be used anymore. How can I either avoid that the font is automatically resized or how can I force wm5 to resize all the components according to the display size In .NET 1.1 CF this happened automatically without, why does .NET 2.0 behave different Tag: .NET Compact Framework serial port error on power off/on Smart Device Development

    - Tray Icon in C# in WM5 Dear Perarg, I write a sample code for you. Hope that can give you some ideas. I just use Notification control in .net CF v2.0. See: 1. Initialize the notification control as follow: notification1.Text = "demo" ; FileStream IconStream = new FileStream ( ".\\My Documents\\setup.ico" , FileMode .Open, FileAccess .Read); notification1.Icon = new Icon (IconStream, 16, 16); notification1.Caption = "Notification Demo" ; notification1.Critical = false ; notification1.InitialDuration = 0; notification1.Visible = false ; 2. Setup a global variable to indicate if the form is minimized Boolean isMinimized = false ; 3. In the Deactivate event handler of Form if (isMinimized == false ) { notification1.Visible = true ; isMinimized = true ; } 4. In the BalloonChanged event handler of notification if (isMinimized == true ) { if (e.Visible == true ) { isMinimized = false ; this .notification1.Visible = false ; this .Show(); } } Regards, Zero Dai - MSFT Tag: .NET Compact Framework serial port error on power off/on Smart Device Development

    - UPDATE MICROSOFT VISUAL STUDIO 8 There are no fixes available and won't be for a while. Also the fact your application does not work does not necessarily means there's an issue with VS 2005 which is used in many other projects quite successfully. I use VS 2005 almost every day and it sure is ready. As with anything, is has some issues, but nothing average developer can’t handle. Perhaps something's not right with your code which might be known working on some other platform but needs to be ported and changed in order to work on PPC. In most cases you don’t just grab some code, recompile it and run it on a new platform, you need to tweak and fix it before it would work, process known as "porting". Anyway, if you believe you have found a bug in VS 2005, it won’t be fixed unless you’ve reported it. You can do that via product feedback site below. Please make sure to include complete and compliable repro code or full VS 2005 project along with description of expected and actual result as well as all relevant software (VS and OS versions) and hardware (e.g. device make/model) information. http://connect.microsoft.com/Main/content/content.aspx ContentID=2220 I’ve just looked up your other posts and it appears issues you're experiencing have nothing to do with VS.

    - NotSupportedException.....from ascyn webservice call? Sadly .net CF v2 isnt an option right now.... The error I get when i remove all error handling is: An unhandled exception of type 'System.NotSupportedException' occurred in OpenNETCF.Windows.Forms.dll Additional information: NotSupportedException So....some new information.... The opennetcf dll seems to be involved......though I don't know how, given the error occurs during a webservice call, and the dll isnt called or used in the specific class where the error happens, though the classes that call this class have some opennetcf elements, like a linklabel and a groupbox.

    - Function of List Box Than you should place it in the OnOnitDialog of the form where you have the list box on. Visual Studio 2005 does not create that automaticaly for new dialogs. You will have to select the class of the new dialog in class view. right click on it and select properties. Then in the properties you have to go to the overides and add an handler to OnInitDialog. Now you have the OnInitDilaog in your new dialog. There you can place the code. If you have eVC you have to start the class wizard and go to the message map tab. Tere you have to add an handler for WM_INITDIALOG. Tag: .NET Compact Framework serial port error on power off/on Smart Device Development

    - Execution on Emulator and Real Device, and local storage *greetings* 1) i am confused over the behavior of the execution on the emulator and real device. i encountered 2 situations as below : i) In the emulator ,the tab button switches well, but it couldn't switch to the intended page when executing in real device, it couldn't display the intended page. ii) In the emulator a connection to Sql server 2000 to retrieve information failed and showed the error that the sql server does not exist, but in real device i can retrieve the information from database 2) Is the ability of debugging supported in .net cf because the only way for me to execute my application is using ctrl + F5. Other than that, nothing else works. Can anybody suggest to me alternative ways, so that i can debug 3) if i am not mistaken, by using dataset, a copy of the information that i retrieved from the database will be stored on my pocketpc. How does this happen and where is the exact path that the data is stored how do i retrieve the data for later use How do i convert the data that i retrieved into XML file and retrieve from the XML file fyi : im using .NET CF 2003 and sql server 2000 All helps, advises and suggestions i thank in advance.

    - NotSupportedException Hi The easiest way to manage files is to copy them in the File explorer of the device/emulator, by this way you will have just to call it directly, or in the directory "my documents" and the full path in this case will be "\\my documents\\filename.txt" Ilya, do you mean by Comment You can set that from emulator's properties. That is of course not available on real device hence you should not relay on that in your application. the setting File->configur/Shared folder so by this way the directory will be added as an external storage card to the emulator, and just by copying the content of that directory in the storage card of the real device, we will have the same functionality without any problems Regards Hammadi Tag: .NET Compact Framework serial port error on power off/on Smart Device Development

Re: .NET Compact Framework serial port error on power off/on

Bob Schaefer

On a power cycle, the file handle has gone invalid, so the object no longer has valid pointers. The easiest thing to do, is to re-create the port object and then open it. This is what works for me.
