    - cab uninstall problem without removing the installed registry entries my dev env: winxp en, vs 2005, winmobile sdk 6 i modified the MapiRule sample program slightly to make my test, basically I separate the sample MapiRule.cpp into 2 files: one to deal with the COM factory, the other to handle DLLMain and the 4 exported DLL functions. I generated a new CLSID too. I created a cab project for my modified sms filter, added corresponding registry entries and packed the compiled dll without error. So far, everything works quite well except only one thing abnormal. My modified version was installed on the winmobile 6 professional device emulator successfully and catched the zzz'ed smses as intended like a champ, but it just can't be uninstalled cleanly! The program directory is removed, but the added registry entries remained in the system registry! I checked the sdk sample program and found the uninstallation removed its added registry entries cleanly. So I have 2 questions: 1. Why do we have to add the program registries in both the .inf file (using cab project registrz editor) and also hard code the adding operation in the .cpp file (insert in DllRegisterServer() and remove in DllUnregisterServer()) Aren't these two duplicate 2. Back to my modified program, I didn't really touch the 4 exported DLL functions including DllRegisterServer() and DllUnregisterServer() except a new class id, could you infer any possible reasons that my .cab can't be removed cleanly on a device emulator I have no physical device around so i only tested on the device emulator. However, the outcome should not be different. Tag: Smart Devices General Remotely triggering events on device Smart Device Development

    - Deploment Path for debugging How can I setup the deployment path for debugging, such that it is independed for each user, i.e. the particular setting must not be in the *.vcproj as this is under source control and nobody should be forced to check out a project just to change the deployment path I am using VS 2005 and want to deploy onto a Smart Device with CE 6.0.

    - Square-Screen support and still have Device Orientation Awareness ?! Hi there! I am trying to port an elder MFC C++ Application to Visual Studio 2005. In the process of doing this i added Device Orientation Awareness and DPI Awareness.. This all works fine, but now the catch is, square devices won't work anymore. I naturally had to add a horizontal and vertical layout for every single dialog form. I really don't want to have another layout for square devices and in most cases the number of controls on the layout won't fit on a square device anyhow. So i was wondering, whether there is an easy way to say: If square device, enable a horizontal or vertical scrollbar. As long as the program was not Device Orientation Aware and DPI Aware i got that scrollbar automatically. Now it's gone, but i would need it back only for square devices. Is there a way to enforce it, or do does the benefit of horizontal layouts come on the costs of square-devices Regards, Tobias Tag: Smart Devices General Remotely triggering events on device Smart Device Development

    - low level key handling for WinCE 5.0? I am using WinCE 5.0 programming in C# and am trying to do the following things: * Catch all key press events for my entire application (multiple Windows forms) in one place * Use one of the physical keys of my handheld device to raise a key event using the virtual key codes that do NOT correspond to regular keyboard keys, i.e. "VK key ranges reserved for specific original equipment manufacturer use: 2A, DBE4, E6, and E9F5" As I understand it * The MessageWindow .NET class does not work because it only catches events generated inside my program and this does not include the keyboard or the physical handheld keys (which are mapped to the keyboard). * I cannot use SetWindowsHookEx to catch low level keyboard events (WH_KEYBOARD_LL) because this is not available in WinCE (it works on a Windows Mobile 5.0 emulator but does not work on my desired WinCE 5.0 handheld which is not Windows Mobile) * The simple .NET key events i.e. S ystem.Windows.Forms. Key(Press)EventHandler can only be used to send key events to the active form (as opposed to the entire applicataion) and KeyPress does not appear to catch key events for virtual key codes that do not correspond to regular keyboard keys but KeyUp and KeyDown do catch them The only solution I can think of is to create a common base class for all of my forms and set KeyPreview property on all of my forms to True and catch all of the key events that way using KeyUp and KeyDown. Is there a better solution I would prefer to catch all of the key events in one place as in the low level keyboard events Tag: Smart Devices General Remotely triggering events on device Smart Device Development

    - Creating a new connection in Connection Manager Hi all, We have a scenario in a project here where we would like to be able to programatically add new connections to various APNs within an application on a WM5 device. I have taken a good look around and can find quite a few ways of connecting to existing connections (which we already do in this application) but cant seem to find a way of adding a new connection. If anyone could give me a starting point to look at or has done anything similar we would be extremely appreciative.

    - Winsock API, Emulator and ActiveSync Hi, currently I try to write some network code for Windows Mobile 5 as well as for Windows CE 5 StandardSDK. The problems I have can easily be shown by using the getnameinfo() function from the Winsock2 library. Now the issue is, on the standalone x86 emulator I can use getnameinfo() and it returns me a valid address for an IP. That one uses StandardSDK. The same applies for Windows Mobile 5 on a Dell Axim 51 device. It works fluently. But using the Device Emulator and the Windows Mobile 5 Pocket PC image takes me into big troubles. First I have to admit, I got it even running as long as I avoided ActiveSync by following this tutorial: http://nino.net/blogs/nino/archive/2006/01/20/WM5EmulatorInternetConnectivityWithoutActiveSync.aspx In that case getnameinfo() returned me valid information for each address I tried (internal DNS, global IPs, localhost). But because of certain reasons I have to rely on ActiveSync as this one provides me the opportunity to communicate with the device by using the CeRAPI on the desktop. If I cradle the device I also managed to be able to browse the web and intranet pages. So for the internet explorer name resolution was no problem. But using the winsock API failed. The error code was 11001 or 11004 in most cases, varying arbitrary. It seems like ActiveSync lacks functionality for stuff like this So is there a way to be able to have both in harmony winsock as well as ActiveSync I took a look at the DMA Channel communication sample code by the Device Emulator and considered writing my own RAPI implementation, but as even the small example fails on WM5, I'd be happy with another solution. Thank you for your help in advance. MK. P.S.: I think I forgot to mention that the code worked on the device when cradled and synced with ActiveSync. My guess is, that it is related to the "Advanced Network functionality" option provided by the device. Tag: Smart Devices General Remotely triggering events on device Smart Device Development

If you want to load what I have so far and see what I mean, the manifest can be found at http://www.incendy.com/MyRSS/rssgadget3.xml Basically the css is very different and also the function that rebuilds the list does not really work on Spaces and you have to manually refresh the page to get the new feed. Just curious if others have experienced this and have advice on what I should be doing differently. The function getfeed gets called but the content seems to be cached on Spaces where it works fine on live.com! Tag: Smart Devices General Remotely triggering events on device Smart Device Development

    - Dynamically Populating ComboBox or Select Option Hi all, Is it possible to populate a ComboBox or Select element via script after the page has loaded I want to have a drop-down with a dynamic list of items in my settingsUI, but can't seem to add items or options to boxes. Also, I am trying to do this with vbscript. It would be best if I could repopulate the drop-down on drop-open (onbeforeactivate ), so that it was always up to date, but if there is a way to at least add a dynamic list once on or before load that would work too. I have tried various approaches to the Select element, mostly similar to the technique here: http://www.microsoft.com/technet/scriptcenter/resources/qanda/aug05/hey0815.mspx Like with the ComboBox below, scripts running in my Windows Sidebar gadget just quit when I attempt to selectName.add newOptionElement I have attempted to work with the ComboBox also, as described here: http://www.microsoft.com/technet/scriptcenter/topics/activex/combobox.mspx I have used ComboBoxes before in other situations, so I think I have the syntax and everything right, but the scripts just quit at ComboBox1.addItem "Sample" or any variation thereof. I can probably find another method of making these options available to users of my gadget, but a ComboBox would be the best solution. Can Windows Sidebar gadgets have dynamically populated select-lists, and if so, how can I do it Thanks! Tag: Smart Devices General Remotely triggering events on device Smart Device Development

    - How to enable/disable body onclick to avoid body drag when dragging div object I am trying to create gadget where I want to do div object swapping by mouse drag n drop. I managed to get this work in IE. When I run it as sidebar gadget, I found an issue with the gadget body event where I don't want it to get dragged when I try to drag my div object. One work around is to disable or set document.body.onclick = "javascript.event.returnValue = false". The problem with this approach is that I don't have ability to undock my gadget by dragging the body anymore. I have to enable it. My question is how to enable back the body onclick once you disable it. Anyone has a better solution for this type of problem I tried to look from the vista stock gadget code but could not make sense out of it how it does this. With vista stock gadget basically there is a region of body that is draggable and some other portion is not draggable. My guess is that it defines some div region where the draggable send the onclick event back to the body but the other is not. How do we do this The following is the code: Code Snippet <script> ... function BodyDrag(enabled) { document.body.onclick = "Javascript.event.returnValue = " + enabled; } </script> </head> <body onLoad="onLoad()"> <DIV id="bar1" class="bar" unselectable="on" style="background-image:url(divbar1.png)" onMouseOver="BodyDrag('false');" onMouseOut="BodyDrag('true');"></DIV> <DIV id="bar2" class="bar" unselectable="on" style="background-image:url(divbar2.png)" onMouseOver="BodyDrag(false);" onMouseOut="BodyDrag(true);"></DIV> <DIV id="bar3" class="bar" unselectable="on" style="background-image:url(divbar3.png)" onMouseOver="BodyDrag(false);" onMouseOut="BodyDrag(true);"></DIV> <DIV ID="floater" style="visibility:hidden;position:absolute; background-image:url(floater.png)"></DIV> <DIV ID="txt"></DIV> </body> </html> Tag: Smart Devices General Remotely triggering events on device Smart Device Development

    - Astoria.Client futures? On a quick look it seems as if the client library doesn't require WCF, i.e. .NET 3.0.+, with just plain 2.0 System.Net.HttpWebResponse/Resquest(!) used.

    - Disable start-button to get into kiosk Hello, I know that I am not the first asking the question about running a PDA in kiosk mode. What I did by now is to disable the taskbar by running the following line of code [DllImport("coredll.dll")] public static extern int ShowWindow(int hwnd, int nTaskShow); The goals was to disable the start-button by hiding the taskbar. This didn't work out (otherwise I would not write this post...) Then I found something about the SHFullScreen command and the way to use the SHFS_HIDESTARTICON parameter. This command was compiling and I could test it on the PDA however the start-button still was there and if you hit it quit often in a short timespan the whole PDA software crashed. So I might have done something wrong. So I wonder - has the SHFullScreen command the ability to disable the start-button and if so can you give me a few lines of code, please. I checked out the whole forum and I couldn't find someting that worked out well for me - also nothing on the OpenNETCF Forum. So if you pls drop a few lines of code for me I'd be very grateful.

Avi G.

Hi,

I would like to develop a Windows Mobile application that will need to synchronize with a server in near real time (up to 1 second).

The device is connected to the network.

I taught about using a constant TCP/IP link between the device and the server but I heard that there might be some problems with that:

- It consumes the battery.

- The IP of the device might change.

Does anyone has experience with that

The second approach is that the server will somehow activate a trigger in the device and the device will open open a connection to the server, is this possible

Thanks,

Avi Golan.

Re: Smart Devices General Remotely triggering events on device

Ilya Tumanov

The second approach and the first one are exactly the same: first one "activates a trigger" via network and TCP/IP. If you have some other phisical connection you can use that connection and ��activate a trigger�� somehow . If not then you simply have no choice but to use TCP/IP.

Whatever IP can change or not depends on networking setup. You can use static IP so it would never change if you're in charge of netweorking.

As to power constantly running device consumes even more than networking.
