 - Bluetooth GPS Hi I'm trying to receive data from a Fortuna BTGPS. I've written a class that reads from the serial port(COM5 on Qtek2020) P/Invoking the coredll. Now, every time i call ReadFile function it reads 0 bytes... I've also tried OpenNetCf serial class but I have the same problem, no data is read. Maybe some permission? I'm really losing my mind...

 - Encryption in XML file I am encrypting string values and storing them in an XML file using the Crypto class in the MSDN Signature sample and the DataSet class to read/write XML. Which encoding method should I use (Unicode, UTF8?) to convert strings to byte arrays? The Crypto class uses byte arrays for encrypting and decrypting. Tag: TEA encryption? Tag: 35380

 - MissingMethodException when creating, disposing and destroying a lot of forms, or when allocating/deallocationg memory Hi: I'm working in an application that runs in C# (.Net CF, Pocket PC 2002, Windows CE 3.0), and loads a lot of forms into memory (for performance reasons). After loading all these forms, this application tryes to call a method in a not-shipped DLL (some DLL shipped with our application). This call is made using the DllImport directive. When the call is made, we receive a MissingMethodException error. Never ever give up - we decide to create an small application (in C#), and two DLL's in native C++ (using embedded C++ 3.0) - one that uses MFC, and the other pure. When the MFC DLL is compiled in Debug mode, we get an error when we try to use some method on that DLL after creating a set of eight forms or/and allocating 8 MB of RAM, for example. The non-MFC DLL very rarelly generates some error. But this happened one or two times. When compiled in Release mode, it's possible to call the MFC DLL in a much more stable way. Anyway, I'm not confident with this solution. I believe that I have a problem, that is resumed on this: 1. When allocating and deallocating a lot of recourses, garbage collector does not collect anything; 2. After that, I can't call a big DLL (always) or, sometimes, call even a little one. All these problems seems to have the same reason: Garbage Collector is not making his part of the job. Even when I force the GC to run (using the GC.Collect() and GC.WaitForPendingFinalizers(), and then a GC.Collect() again, the problem occours. But I can't get the problem when I use the VirtualAlloc Windows API to alloc a big set of data (and this API is deterministic - when the VirtualFree is called, all memory is deallocated - with the exception of a few bytes - when the cicle is run again, all bytes are freed). My question is: how can I really ensure that a resource allocated in the .Net platform is really deallocated when I want? Is there any trick, any secret, am I doing something wrong? I'm working on this for hours, have STFW and can't find nothing usefull - I found a funny document at http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dncenet/html/advmemmgmt.asp that explain some limitations on Pocket PC 2002 architeture.

 - Data storage solution advice sought... Ok, here's my scenario: -I am creating an application that will work with data extensively -The data storage solution will come pre-populated with a large amount of data from me, (about 1 or 2 MB's worth) -the user is free to modify, and add data. In fact the 'adding of data' is expected. I would expect the big users to add 1 to 5 more megabytes worth of data, although I don't want to place any real limit on the user. I could see someone with a storage card wth a 100MB db if they store images in the database, as it will allow. -Replicating with a SQL Server will not be offered as an option as this is for consumer, not commercial use. -the ability to back-up the db will be required in some form (xml dump, copy db file to host machine, etc...) - I have considered, but have not committed to, developing a desktop version of teh app for easier input. I am loathe to do this however and, as such, rate the possibility as low. -the data stored in the database is relational - I would like to password protect and encrypt the database. I don't want anyone using the data I am going to seed the database with. I see several options: SQl Server CE 2.0 (which is what I am using now in my development), XML files, Pocket Access, SQL Server 2005 Mobile. SQL Server CE 2.0: PROS: fastest solution? I'm comfortable with it. Database can be locked down and encrypted. relational database. CONS: my main concern is the size of the DB dlls, the fact that only one database can be opened at a time, and the lack of a clear backup strategy since my customers will not have SQL server desktop version to replicate to :) XML Files: PROS: no storage overhead. CONS: just seems messy. In addition, I have to deal with image storage and relational data. Just doesn't seem right to me to use XML files in this case. Pocket Access - PROS: I understand that I can use ActiveSync wupport to backup the database. Can I merge a desktop Access database with the Pocket Access data? CONS: No CF support. I just can't seem to find much about Pocket Access. I find articles on how to access data - but how is the database created in the first place? How do I construct a Pocket Access DB? I have a schema already created in SQL Server and I have data already stored in it. How do I get this schema and data into a Pocket Access DB? SQL Server 2005 Mobile - PROs: ? CONS: still in beta (but should be out by the time I am ready to release). Doesn't seem to solve many of the problems I have with SQL Server CE 2.0. It does, however, allow more than one connection to the DB at a time - at least, so I have been told. My question, after all of that, is so I have my facts straight? and what would others recommend? BTW, I am not that concerned over the SQL Server CE overhead. I reckon that anyone who will purchase my program will have no problem acquiring a storage card upon which to place their data (I know that this doesn't directly address the sql dlls). I just think that in the end, it will all even out... for the market segment that would be interested in my product. So I'm thinking that this "con" probably isn't a deal-breaker for me. I'm more concerned about what data backup solution I will be able to provide my users, especially if they are storing their db file on a storage card and not in their 'My Documents' folder.

 - Debug web app project always build and deploy smart device applica Hi, I have a solution that contains both a web app project and a smart device app project (window application, not a class project). However, after I set my web app project as a start up project and a web page inside as a start up page, and I hit F5, it always build and deploy my smart device app project. But If I right-click the web app project and click debug > start new instance. It works fine and debug only the web app as usual. I have tried create a new web app and new smart device app in a new solution. This still remain the same. Not being able to F5 is quite annoying at the time of debugging the web app. I just wonder if anyone can give me some help. Is there some settings that I missed or is there somethings that I can do to solve this issue? By the way I am using VS.NET 2003 Enterprise on XP Professional. Thanks a lot, Eric Tag: TEA encryption?

 - ContextMenu - reproducible crash, CF 1.0 SP2 To Microsoft CF team and list, I have previously posted information on this topic but I now want to open another thread here after I have worked on this problem for a few days now and want to share some information. I have CF 1.0 SP2 and have been trying to get a ContextMenu working without success. I keep getting a System.ArgumentException error. What I am trying to achieve is to have a ToolBarButton set for a PushButton style raise a ContextMenu when tapped. This part works as expected. As background, I chose to use a ToolBarButton with PushButton style and a separate ContextMenu instead of a ToolBarButton with the DropDownMenu style set because I have found that for some Pocket PCs running PPC 2002 this latter combination causes the Pocket PC to freeze after a couple of taps on the menu. Having a ToolBarButton set as a PushButton and using a separate ContextMenu overcomes the freeze problem on those Pocket PCs. However, I also have various conditions in my app where I want to display different menu items in the ContextMenu. When such a condition is encountered in my app, I call a method and simply run ContextMenu.MenuItems.Clear() and then begin using the Add() method to add the new set of menu items. Theoretically, this should work every time, but it does not. I have now proven beyond doubt that a second call to my method that first "clears" the MenuItems collection then "adds" the new ones will crash the system IF the ContextMenu has not yet been displayed. After much testing, it seems that the ContextMenu needs to be displayed first each time after you Clear() then Add() a new set of menu items to avoid the error message. Displaying the context menu at the wrong time so a user can dismiss it just to rebuild the next set of menu items is pretty ugly. This is the only workaround I can find. Does anybody know of a way to programmatically dismiss the ContextMenu in order to provide this workaround? For anyone interested, I can send you my VS .NET 2003 solution files that will demonstrate this problem. Does anyone have any other method of building different menu items for a ContextMenu? Does anyone know if CF 1.0 SP3 Beta or even CF 2.0 Beta fixes this problem? Regards, Neville Lang Tag: TEA encryption? Tag: 35334

 - Application Foreground "Timeout" I have a kiosk-type Pocket PC app which has a problem of moving to the background after the device has been powered down with the power button. For short durations of minutes to an hour or two, the app is in the foreground. This only occurs after the device has been off for a relatively long time. (e.g. powered off overnight). I'm sure the app is still running because pressing a programmed HotKey causes the top portion of my app to appear over the title bar. And then tapping that exposed area of my app's screen restores the rest of the app to full view. I've tried using the BringToTop()/SetWindowPos()/ShowWindow() API commands in the form's GotFocus event to no avail. (In VB6, this code keeps the window on top no matter what; similar to a MsgBox with vbSystemModal.) I suspect that it is not my app that goes to the background but rather something in the OS that forces the Start screen to the foreground. This application is used in scientific experiments. In a controlled lab, this might not be such a problem. However, the app, being PDA-based, is also used outside of a lab. Therefore it is imperative that the app never go to the background. (To prevent subjects from running down the battery, and inadvertent or intentional deletion of the app & its data; and to some extent, give the appearance of a dedicated device which helps dissaude theft.)

 - Form Activate - Can it be bypassed? Hi, I have code in the Form_Activate event of my application and as the user needs to switch between many forms, I simply hide them when the user needs to move to another form. At present, I have a global boolean called gbExitNow and set this to true and test for its condition in Form_Activate, in order to bypass the code in Form_Activate when the user switches to another form. I'm sure there is a more efficient or programatically correct way of doing this and was wondering if someone can please provide an alternative method where I can bypass the Form Activate at certain times. E.g. when the user selects "Save & Exit" the save routine is performed, the form_activate is executed before the form is hidden. Thanks in advance for any assistance. Kind Regards, David.

 - Speeding up the drawing of forms and their controls... I was under the impression that there was a way in which I could create a populated control off-screen and then quickly show it (by this I mean that no time is saved in the end, just that the user sees an 'instantaneous' display when it does appear). I have a custom control that I create and initialize off-screen (I just set the draing point to somethign not visible) and then I changed the drawing point to be 1,1, which is where I wnat it. The net result is no apparent increase in performance on the drawing. I still see individual button controls being drawn one after the other. I'm thinking I may be barking up the wrong tree.

 - Detecting mains power Does anyone know of any way of detecting whether a device has mains power or not? I can see power state changes, but can't tell from them whether the device is connected to a decent power supply. (We'd like our app to keep trying to download updates if it's on mains power, but not otherwise.) -- Jon Skeet - <skeet@pobox.com> http://www.pobox.com/~skeet If replying to the group, please do not mail me too Tag: TEA encryption?

 - OpenNETCF: Bug in Process.Kill? I was just having a look at the code for Process.Kill, and it looks somewhat wrong to me. In particular, it calls OpenProcess (0, false, this.Handle) but this.Handle is actually the result of calling OpenProcess in the first place with the process ID. Should the code not just call (after checking for exit etc) TerminateProcess (Handle, 0); ? Why the two levels of OpenProcess? The last parameter of OpenProcess is a DWORD, not a HANDLE, which also suggests there's something wrong. On a different but related matter: have I overlooked something, or does OpenNETCF not currently have a way of enumerating processes? If that's correct, is there any reason for it other than no-one's done it yet? It's definitely possible using Process32First/Process32Next with the results of a CreateToolhelp32Snapshot call. -- Jon Skeet - <skeet@pobox.com> http://www.pobox.com/~skeet If replying to the group, please do not mail me too Tag: TEA encryption?

 - Pocket PC Setup Applications I've built an inf, ini, and cab with cabwiz. Everything compiles and then I create a setup.exe using the EzSetup application. I can run this but after the Readme, Eula, I get an error that there's a problem in the Setup file...... Then i thought, here's a way to to it the .NET way when i read the article Developing and Deploying Pocket PC Setup Applications from Microsoft....Download the code and it doesn't compile and what your suppose to do to connect the pieces is less than intuitive. Is there a recommended article on how to build a PPC setup program? I need to install SQLServerCE cabs, Symbol cab as well as the app cab. I also want to "include" a local database DB.sdf. Any good recommendations? TIA Harry Tag: TEA encryption? Tag: 35180

Hi,

is there any TEA-Encryption source (C#) available? i just have found some

If someone has converted this en/decryption to C# already i would be really
appreciated if i could use this sources too.
