- 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: .NET Compact Framework Full Duplex Audio Player Smart Device Development

- 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: .NET Compact Framework Full Duplex Audio Player 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: .NET Compact Framework Full Duplex Audio Player 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.

- Remotely triggering events on device 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.

- Gadget behavior on spaces vs live.com? Strange. I just checked out couple gadgets of my own that do the same thing to break the cache and they work just fine up on Spaces. I tested both the generic proxy and the RSS proxy and saw no difference. The only difference is that my gadgets pull apart the RSS feeds using XPaths while yours uses Start.Parser.RssParseResponse, so perhaps the caching is happening in the parser. Try some simple alert()-style debugging. In OnFeedReceived, do an alert(response.responseXML.documentElement.text); and copy the output for several refreshes (you can ctrl+c on the alert() message box). Save the output into different files and run a diff on them (using a tool like windiff, if you have it). If they're different but you're still getting the same output as if it's cached then something's going on in Start.Parser.RssParseResponse and it's time to look into parsing on your own :). Here's a link to the w3c.org XPath spec . That's a little dry reading but it covers XPath syntax fairly well. You can also lookup the selectNodes() and selectSingleNode() methods for the javascript XML document as those are the functions you'll use to apply XPaths (the former returns an array of nodes that match the XPath, the latter returns only the first matching node). Here's an example of code to parse an RSS feed using XPaths. var items = response.responseXML.documentElement.selectNodes( "//rss/channel/item" ); if (items != null && items.length > 0) { m_videoItems = new Array(items.length); var len = Math.min(items.length, 25); for ( var i = 0; i < len; i++) { var link = items[ i ].selectSingleNode( "link" ).text; var guid = link.substring(link.indexOf( "vid=" ) + 4); var imgSrc = items[ i ].selectSingleNode( "media:content/media:thumbnail" ).attributes.getNamedItem( "url" ).value; var title = items[ i ].selectSingleNode( "title" ).text; } } Tag: .NET Compact Framework Full Duplex Audio Player 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: .NET Compact Framework Full Duplex Audio Player 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. Is that the longer term plan (it's ok to guess :-) Plus, as well as a JSON serializer/deseriler, an object statemanager and a nice wrapper over the GET/POST calls, what would I lose if we don't use the client side library Is the longer term strategy to keep the Astoria client/service as some that should be always be used together or is it ok to 'go naked' on the client and just use the service side wrangling David Tag: .NET Compact Framework Full Duplex Audio Player Smart Device Development

Also, I noticed that the speaker repeats what I record from the beginning, its like a loop expect the noise.
So maybe the problem is in the FifoStream
