    - Problem out of memory Hi, I'm working on Pocket PC 2002 and have an application which is displaying a message : "Out of memory". That's the os which is displaying this message. I want just to know if someone has an idea of that problem ? I think that the problem comes from a procedure in the program : the application is calling every second a dll which in order to display the life time percent of battery. Thanks for any information about that problem. Tag: What problems do you face programming for mobile platforms? Tag: 98119

    - XML parser Hi, I need an XML parser. Don't need it to be validating. Do I have to use the XML parser that's built in into pocket internet explorer (PIE)? How do I use it? samples? COM interfaces are unnecessarily difficult to use. Maybe some stable bugree light PocketPC and SmartPhone class out there? Has to be pure API, not MFC or WTL.

    - custom CBitmap class In an effort to make it easier for me to work with bitmaps, without MFC or ATL, I created this class. Nothing spectacular, but I'm wondering if this leaks memory or needs improvement. The thing I find most ugly in writing classes to use with native code, is the HINSTANCE required for many functions.. getting this HINSTANCE seems to be done by storing this in a global variable and refencing it. I store it in HINSTANCE g_hInst; This isn't very portable, because my classes then need to reference to this by defining extern HINSTANCE g_hInst; Shouldn't there be a way to get the instance handle through some API's instead ? Anyway, most important is to make sure this class is usable and doesn't leak any memory.

    - WSPStringToAddress problem in LSP Hi all I have a LSP in PPC. It seems that "WSPStringToAddress" function is always failing because its getting an URL. But this function doesn't resolve URLs. It just converts dot format numeric address to socket address format. What can I do in LSP to avoid this failure? Actually my real problem is, For some reason "the connection arrow icon at the top of the device is always broken even though ANY medium is connected and working fine and the LSP gets all the traffic properly". I went thru all the calls and this is one call that always failed. I am not sure this is the one causing the problem but atleast if I make this fucntion right, who knows, connection icons might be OK :-) I really appreciate any help.

    - finding executable directory Hi, i am using the following to return the path to my executable: Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().GetModules()[0].FullyQualifiedName); the problem is, this is always return //Program Files/<AppFolder> It doesn't appear to be driven off where the executable is located, but rather, what settings you use in VS for Project Properties->Device->Output path Folder. so when i am testing/debugging, it is returning the wrong directory, since my executable is located in /bin/release at that time. any ideas what is going on here or how to solve?

    - Killing Notification dialogues Hi, i have an app i wrote which can intercept the hardware keys and do something. One of the "something" i would like to do is close dialogues when a certain key is pressed. How can i do this? By "dialogues", i mean modal forms AND those bubble notifications on the taskbar. i know how to find a window by it's class, and i know how to send a WM_CLOSE message. i also have a key handler class that can handle the hardware keys "globally" (meaning it doesn't matter what app i am in, i detect when a key is pressed)... my problem is, i can't seem to detect when one of those lil taskbar bubble notification dialogue appears and i cant seem to "find" them. I assume when the show up, the have the focus, since if i am typing and they appear, i have to click back to where i was to continue typing. However, GetActiveWindow does not return a valid Ptr/Handle when they pop up. I also cannot find them because i do not know the Window Class for these notification dialogues and i am currently not able to get Remote Spy going on my machine for some reason. any assistance would be greatly appreciated Tag: What problems do you face programming for mobile platforms?

    - Is there maximum packet size for GPRS transmission? Hi, I just wrote an application for PocketPC 2003, or to be exact, my newly bought Mini O2. There is a TcpClient on the O2, while server application on a PC. If run using WiFi adapter connecting to its public IP (Server on PC), it works.... without any flaw... except initial connection is abit slow like 2 seconds compare to direct private LAN WiFi. And it work..... The problem arise when I am using GPRS. I found while receiving the packet half way, the functions terminated and was catched with errors. So I am interested to know if there is any untold maximum packet size for GPRS? If so, I will re-write some sub logic to transmit my data by multiple of smaller blocks. If you are curious, my original packets are relatively small, around 3kb~12kb.... It is why I did not write the code to send via multiple small blocks. And it prove to work on WiFi. So it must be something to do with GPRS.... Hope some GPRS gurus here can give some lights..... Thanks for reading... Tag: What problems do you face programming for mobile platforms? Tag: 98085

    - AudioVOx RTM8000 und RTM8000D Hi, we uses the AudioVOX RTM8000 CF Card (GPRS/GSM) Now we want to uses a "data only sim card". Thats a card we can use to make gprs connections but no phone calls. Can we use this with the AudioVox RTM8000 Card. We know that there is also a RTM8000D where D stand for "Data ONLY" With the RTM8000D there are no functions for phone only for GPRS ... so this shloud work together BUT we want to uses the RTM8000 with a "data only sim card" ... OK we know that we can't make a call because of the "data only sim card" but thats OK for us. The question is: Do we have to my a "full" sim card (phone with gprs) or can we also use a "data only sim card" together with the RTM8000 card ???

    - TAPI Support in Ppc [The following query is also posted on microsoft.public.pocketpc] Hello Experts, Forgive me for asking such a generic query, this more of an implementation issue. We're currently under planning stage to develop TAPI components for both PocketPC and PC. We've also observed TAPI's availability in two versions i.e. 2.x and 3.x. This is leading us to a confusion of, which one to use!? One of the decision factors can be, which one is more used/supported, both in terms technical and system compatibilities? So, it is very important to know about TAPI's support for PocketPC; 2.x or 3.x? I hope my english isn't too bad or I can re-phrase the query set to get more explanation :) Any comments/suggestion will be helpful for me.

    - Undocumented DLLs / Decompilation Is there any way to use a DLL which you do not have the API for? I have an iPAQ and the camera / consumer ir dll files on the rom (without an API). How hard would it be to work out the function calls / required parameters / return values in such a case? (like, is it impossible?) Would looking at the strings in the DLL file help? Would a disassembler/decompiler help? Are there any for pocket pc's (there are some for win32 and .net but I haven't been able to find one for ppc). Any pointers in the right direction would be appreciated. Tag: What problems do you face programming for mobile platforms? Tag: 98069

    - moving Bitmap between managed and unmanaged code I am trying to move a Bitmap between managed and unmanaged code, so that I can use the Imaging API. The latter is a series of COM interfaces, so I am trying to use it from a dll written in C++. At the moment, I am trying to have the Imaging API create a thumbnail, and display it in managed code. What I have done is: 1. Create a Bitmap in managed code (C#) 2. Use Bitmap.GetHBitmap to get the Bitmap handle 3. Pass the Bitmap handle to a dll procedure 4. In the dll procedure, a. Load the bitmap into a Memory DC b. Use IImage->Draw to draw the thumbnail (previously created in the IImage) to the Memory DC c. Then clean up and return to the calling C# code 5. Display the Bitmap in response to the Paint event in the C# code What happens is, a black bitmap is displayed. No doubt my understanding of how all this should work is in some way flawed, but this P/Invoke stuff is confusing, and I'd appreciate any assistance. I've included some of the code below. C#: [DllImport("dplib.dll")] public static extern void testProc(IntPtr bptr); Bitmap bmp; public ThumbViewer() { InitializeComponent(); bmp= new Bitmap(100, 100); testProc(bmp.GetHbitmap()); } C++: extern "C" __declspec(dllexport) void WINAPI testProc(HBITMAP hBmp) { IImage *pImage; . . . HDC hMemDC= CreateCompatibleDC(NULL); HBITMAP hOldBmp= static_cast<HBITMAP>(SelectObject(hMemDC, hBmp)); RECT r; r.left=0;r.top=0;r.right=100;r.bottom=100; pImage->Draw(hMemDC,&r,NULL); Tag: What problems do you face programming for mobile platforms?

    - Confusion over GetOpenFileName All, I can get the File Open dialog to come up, showing the filter that I want, etc. And I see several files to select from. However, I'm not sure why I can only "Cancel" this dialog; I cannot click on a file to open it! In other words, the call to GetOpenFileName never returns. Why is there no OK button to select?

I want to update the icon on the tray (when the buble isnt visible), every thime I called the SHNotificationUpdate() with the correct flags it will not update it, I have to remove and then add the notification back again. 3. What is the LPARAM in the SHNOTIFICATIONDATA struc good for? In the struct I can setup the LPARAM, but why? When I get WM_COMMAND for clicking on a button, it does not have the same LPARAM as I set in the struct. 4. I got an app that need to display a notification that is always accessible. ie, the icon should always reside on the tray. (Clicking on it will show the bubble). I got everything thing setup, I got my three buttons in the bubble, I got a wnd sink listener for the notification struct that listens on WM_COMMAND. The buttons that are in the bubble will close the bubble, but the notification icon (in the tray) disappears as well. Why does it disappear, and what do I do to stop it? My bubble HTML looks like this: tmp += L"<input type=button name='cmd:1' value='Cancel 1'>"; tmp += L"<input type=button name='cmd:2' value='Cancel 2'>"; tmp += L"<input type=button name='cmd:55' value='Cancel 55'>"; When I click on button 1, the icon and bubble will disappear. When I click on button 2, the icon will not disappear, the bubble still disappears as it should BUT I dont get any WM_COMMAND. (Only one WM_NOTIFY, probably because the wnd is closed). When I click on button 55, the icon and bubble will disappear. My struct for adding it: bubbleData.csDuration = -1; bubbleData.npPriority = SHNP_INFORM ; bubbleData.hicon = bubbleIcon; bubbleData.grfFlags = SHNF_STRAIGHTTOTRAY | SHNF_SILENT; bubbleData.clsid = bubbleGuid; bubbleData.hwndSink = validHwnd; bubbleData.pszHTML = bubbleContent; bubbleData.pszTitle = L"title"; bubbleData.lParam = BUBBLE_LPARAM; bubbleData.cbStruct = sizeof(SHNOTIFICATIONDATA); Loads of questions, but I really need some help as I spent too much time on it already.

    - Text to Speech I'm wondering what the latest/greatest options are for WM 2003 with respect to text-to-speech. After some hunting via Deja/Google it seems: - No SAPI support exists, so no generic interface to use and allow third party plug-ins...therefore all TTS support must be targeted at a specific engine/SDK. - A fully Microsoft-based solution only exists with the new Speech Server. ....please correct me if I'm wrong :-) Regardless of the above, I'm curious how the commercially available engines rate. If anyone has some insight/opinions to share I'd greatly appreciate it! Cheers, --- Eric Drumbor "It's bad luck to be superstitious...."

    - Where do I get .Net Compact Framework? I've been following some old threads about database programming with eVC and there are a few references to .NetCF. Presumably this is a module for VS .Net that allows me to build for ppc, and supercedes eVC3 & 4? My .Net2003 DVD makes reference to it but as far as I can see there is nothing installed and no installer. Thanks. Tag: What problems do you face programming for mobile platforms? Tag: 98004

    - dialog based wizard Hi, Using native API, what is best way to create a 'wizard' type application based on dialog box templates? (Wizard is where multiple dialog boxes are displayed in sequential order, which you can switch between using buttons like "Next" and "Previous") Shoudl I create a dialog box, then destroy it and create the next one, or create all of them and handle switching between pages by making dialog boxes visible or invisible.. I do not wish to use property sheets, or tabs, because I want to be smartphone compatible. I think if I create these dialog pages and destroy them, between switches the today screen might flash because there will be an intermediate time where there are no windows visible. Perhaps create next page, then hide previous.. What is the common way (how is it done on smartphone?) Also, my main application window will be a dialog. And dialogs have a windows classname of "Dialog", correct? Is it possible for me to use my own classname to better use "FindWindow" ? Or is it possible for me to create a generic window, which I register myself, with my own classname, and then subclass a dialog box with it or something? Ideas welcome..

    - Mobile Device Application for inventory tracking Hello. I'm working on a project at work that deals with a handheld scanner for inventory tracking. Currently, we use VisualCE 9.0 to build our form. Its very simple, but that's the downside. We'd like to implement some advanced features, which VCE doesn't support. How well do .NET languages run on Mobile Devices? Our scanner is a PocketPC-based model from LXE. Our resources are not infinite, but if it can be justified, our IT department (from India, no less) can begin development on a new application. Here are some of the business requirements: 1. Must be very easy to use with a very short learning curve. 2. Must be very fast, ie no clicking verification windows, tabbing to the next field, but still have validation rules for the fields. 3. Must have a database back-end. A master file must be loaded and records processed from this master. As they are processed, they must be deleted to assure no duplicate work is completed. Typically, there will be upwards of 10,000 records at any given time, with an upper echelon well into the 100,000s. 4. Must be able to integrate with Access. This could be discarded if an additional application could be built that resides on a desktop, but the scanner must be able to communicate with this application. That's why Access seems to be the easy way out. Again, how easy is it to develop PocketPC applications using .NET? I have some C# experience, but can't remember if its an option or not. Thanks in advance, Matt Tag: What problems do you face programming for mobile platforms? Tag: 97991

    - Viewing an external camera on a Pocket PC Hello all, I'm checking to see if this is possible, and if so, where do I go to find out more. I want to take the feed of a security camera, and display it on my handheld. One camera might be a web cam, one might be a standard security camera. What would I need to do to get the picture on my pocket pc? What do I need to get a non-computer based camera to show up on the network? Thanks Dan dweese@caelumtechnology.com Tag: What problems do you face programming for mobile platforms? Tag: 97990
