    - What is Atomic Sector Writes? This from MS documentation: TFAT requires the underlying block structure to support atomic sector writes. The flash driver and most CF card hardware provide atomic sector write operations. In cases where the block driver is not atomic, TFAT cannot guarantee transaction safety.

Until now, all pockets with all kind of GPS antennes worked (Bluetooth, CF, built-in). A client has bought a Mio A701 with built-in GPS antenna, and we are not able to get it working.

    - Icon on menu as legend I want to make a legend for a map by creating a menu item legend. That would have all categories of layers (geography, restaurants, ...) of the map. Each category can then expand showing all individual layers of the category (Cathedral, ...). I know how to create the menu part. But can I also use icons for the legend items (a blue square could stand next to "Water" for example). This would be necessary for both the categories and the individual layers. eVC4 (MFC) on PocketPC 2003 SE Tag: how to call a C function in vb.net compact framework Tag: 109503

    - Media player 10 ActiveX controller in PocketPC 2003 SE application Hi all, I'm trying to create an application for an iPAQ that uses PocketPC 2003 SE. The application should use the ActiveX controller provided by Windows Media Player 10 SDK. I've installed the WMP SDK, the PPC2003SE SDK and eVC++ 4.0 SP4. I've followed the instructions on http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wmplay10/mmp_sdk/embeddingtheplayercontrolinanmfcproject.asp. The wmp ActiveX controller isn't found in the "Add to project > Components and controls..." dialog, so I use the "Add control" button to locate and add the wmp.dll from c:\windows\system32. Is this correct? I've got a suspicion that the control added should be the wmp.ocx, but when trying to add that one, I get an error message saying "Failed to find desktop version of control in registry. Please verify that this control has been successfully registered on the desktop." How do I register the wmp ocx so that eVC++ finds it? Do I need to reinstall the WMP 10 SDK? However, after adding the .dll file to the project, a WMP icon appears in the toolbox of eVC++ and I'm able to add it to my form and assign buttons etc to it. But when deploying the application to my Pocket PC, the WMP component isn't there and the buttons have no effect. Is this because I use the .dll instead of the .ocx? Any ideas on how to get this thing working? Best regards, Fredrik Boström Tag: how to call a C function in vb.net compact framework Tag: 109500

    - Synchronize Mail After multiple posts I am still no further: I am trying to synchronize email from a POP3 account programatically. In 2003 SE this uses the messaging app. People have suggested simulating a send/receive. I have done this but this is unreliable as after connecting, the menu item becomes Disconnect and so one must disconnect and the Connect. Since the Disconnect may take time it is difficult to determine when to start the Connect. Other suggestions are to pass parameters to tmail but no one seems to know what these parameters are. I would prefer to use the mailtrns.dll transport as this seems to give the most control, but I seem to be instantiating the callback incorrectly. Does anyone know how to do this. I have tried to do this as follows: I get the ONESTOPFACTORYFUNC and can call the IMAILSYNCHANDLER without a problem. I cannot seem to get my callback to work. The callback calls the correct methods within the class that I create (I can stop it in the debugger inside the calls )but throws an exception "Datatype Misalign" on return. If I omit the Addref method from my callback it calls Progess and I can see that the incoming parameters are also incorrect. I assume that the way I create this class therefore is incorrect. I simply instantiate the callback using new ... - Should I be doing something else as it seems the parameters are not passed in the way the class is expecting them. My callback class looks something like this (just the first few lines included for brevity) public: CMailSyncCallBack(); ~CMailSyncCallBack(); HRESULT STDMETHODCALLTYPE QueryInterface (REFIID rif, LPVOID* ppobj); ULONG STDMETHODCALLTYPE AddRef(); ULONG STDMETHODCALLTYPE Release(); MAPIMETHOD(RequestSync)( LPCWSTR pszProfile, DWORD cbCookie, LPBYTE pbCookie ) ; etc.... I instantiate the class and then call initialize like this: CMailSyncCallBack *ms = new CMailSyncCallBack(); hr = pIMailSyncHandler->Initialize((IMailSyncCallBack *)ms, _T("POP3"),pMsgStore); Should I be doing this some other way as clearly the parametes are not being passed correctly.

    - Guidance in writing WLAN software for PocketPC Hi! I am planning to write a WLAN software for Pocket PC and Linux. I can program in C and have fairly good knowledge of 802.11 MAC and have read (and got a good understanding of) the standard. I am don't have idea on what is the starting point in gaining the skills needed to write the software. The software finds the SSID's available (and info such as type of network, infrastructure or Ad-hoc), tries to associate/authenticate to a signal based on their security configuration (WEP, WPA-TKIP, 802.1x) and get other information such as signal strength etc. Thanks in advance, BB.

But now I want to see what counter has been clicked.

    - TreeView control - determine which TreeNode was selected w/MouseDo Does anyone have a good way to determine which Node is selected, using Mouse functionality (versus using the TreeView_AfterSelected method)?? I've scene the documentation that states there should be a TreeView.GetNodeAt(Point) method which would allow you to trap the X & Y coordinates of your mouse via the MouseDown() event handler, then create a Point object from those coordinates, then use the GetNodeAt() method to determine if any node falls under that point .... problem is this doesn't seem to be an available method for CF v2.0 apps. What I'm attempting to do is have a context menu dispaly, with relavent choices, but only if the user is directly over an actual node. My problem is the TreeView control allows the context menu to display even though the user is in an empty area of the TreeView object .... no Nodes directly under the stylus. I only want the context menu to display when the user is directly over an actual Node. Thanks -- Stay Mobile Tag: how to call a C function in vb.net compact framework Tag: 109462

    - button-mapping at screen-orientation DMDO_180 Hi all, an observation we did is that hardware-buttons are not re-mapped in the portrait flip mode DMDO_180. On almost all machines we test, buttons are not remapped (so up/down and left/right are actually down/up, right/left). All landscape-modes work fine. If the behaviour would be the same on all it wouldn't be a big problem, but..... now the e-ten M600 uses a landscape-mode button remapping for DMDO_180 !!! So, what's the correct behaviour for a machine ? Undefined ? No remapping ? Or, are they ALL wrong and should they remap ? Does anyone have some more info ?

    - Make viusal studio deploy dll in the pocket pc emulator Hello, I have a Pocket PC project that uses a legacy dll (implemented in C) for communication. I think I have managed to implement all the PInvoke stuff in my C# .net application, so now my main problem is how to debug the code. When I run Debug on my application, Visual Studio loads the Pocket PC 2003 emulator. As soon as the application tries to call methods on the dll, it fails with the error message: "Can't find PInvoke DLL 'legacy.dll'". The problem is that I haven't found any way to deploy the dll on the emulator before starting/debugging my C# application. How is that done? PS. I'm new both to Visual Studio and Pocket PC development, so even though I've search the net and MSDN for solutions, I'm just not familiar enough to msdn and VS terminology to find my own answers just yet. I'd be greatul for any help here. -- Fredrik Jonson Tag: how to call a C function in vb.net compact framework Tag: 109427

    - CHtmlView base class undefined Hallo, excuse the disturbance but I wish to share a little problem here. I wish to write a dialog-based PDA Application with eVC 4.0 that contains a HTML Page. My so called BrowserView class is derived from CHtmlView (done by the wizard) and the head looks like this: // CBrowserView html view #ifndef __AFXEXT_H__ #include <afxext.h> #endif #include <afxhtml.h> class CBrowserView : public CHtmlView { protected: CBrowserView(); // protected constructor used by dynamic creation DECLARE_DYNCREATE(CBrowserView) The nessescary Header "afxhtml.h" for CHtmlView is already included by the wizard. Nevertheless if I compile the shit I get the error c:\entwicklung\test4\browserview.h(20) : error C2504: 'CHtmlView' : base class undefined I cannot figure out where the problem is and hope anyone here can help me.
