    - VS.Net 2003 and CF SP3 Hardware : Symbol PPT 8800 running CE .NET 4.1 I have a written an application for the above mentioned device and have noticed that some of the problems I was experiencing have been resolved in SP3. When I install SP3 onto the device my application will no longer run, I am getting Could not load type System.Windows.Forms.DialogResult from assembly System.Windows.Forms, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=B77A5C561934E089. When I try to debug the app, i get various exceptions being thrown from Typeload to XMLDocument. These exceptions are thrown as soon as the app is launched, which does help me to determine what is raising them. Any ideas?

    - Custom commandbar/toolbar Hi everyone I am currently working on a project where one of the requirements is to have a toolbar but all the buttons in the toolbar must be big dump your finger on type of buttons like in Tom Tom navigator, the buttons will be made up of a 32x32 picture plus text. So what I am looking to be able to do is create a toolbar that could be docked at the bottom of the screen but would also be able to have a custom button to bring up the input panel or change the input method like the normal toolbar. If I was to have the standard toolbar at the bottom of the screen and just position my toolbar on top of that it would take up to much real estate. Is what I am looking to do possible? I found a post on Google groups from 2003 by Alex Yakhnin about a commandbar control he was developing but I can not find anymore information about it. I would appreciate any help/adivce on this matter. Thanks Dan Tag: Is there any example show how to use USB device under Compact Framework Tag: 49742

    - Audio Capture on Pocket PC 2003 Hi, I would like to capture audio, encode it, and stream it from one Ipaq to another (pocket pc 2003). I have 3 questions relative to this problem. 1) I could not find any information about Audio Capture in my MSDN. What is the simplest way to get the audio samples ? (i am working in C#, CF 1.0 SP3) 2) Is it possible to encode the audio samples using microsoft APIs ? if not, do you know any third party APIs I should consider? 3) Do you think it would be a benefit to upgrade to .NET VS 2005 and Compact Framework 2.0 Beta when it comes out next week ? I heard CF2.0 supports a few functions of directX, that could be useful for audio capture? Thanks a lot!

    - Killing process Hi, I just created my first vb.net pocket pc application - that consists of a main dialog and an additional dialog that is defined globally like this: Dim x as New MyTestDialog As the dialog's constructor takes a lot of time to do all that is necessary, it is called only one time when the process starts - and I just call ShowDialog any time I need to display it to the user. But, when the application is closed by the user - the process somehow seems to remain active (as e.g. the executable is not deletable, the Form_load handler of the main form is not called again,...). I tried to Dispose() the additional form - but nethertheless the problem remains. As the .net compact framework does not contain a Process class - can anyone tell me how I can just kill myself (my own process)?

    - replacement for C++ function 'modf' hi, I was using the following function in a C++ program. I am now "porting" it to C# and I can not find an equivalent to: modf function. As described below. double modf ( double x , double * ipart ); Split floating-point value into fractional and integer parts. Breaks x in two parts: the integer (stored in location pointed by ipart) and the fraction (return value).

    - Does InputPanel work properly on windowce.net devices ? hi all, I noticed that InputPanel is throwing a NotSupportedException on the emulator but not on the device. However I noticed that a general method that I used on Pocket PC witch resize the scrollbar according to the InputPanel state, isn't working properly. And since i m not able yet to debug on the device (troubleshooting), I wanted to ask if there are well known problems about using the InputPanel with windowce.net Anyway, the reason why i want to use an input panel is because on one of the screens, there are textboxes on the bottom of the form that are being hidden by the keybaord, when the keyboard pops up. Is there a solution for that (other than changing the design of course ? -) ) thx *** Sent via Developersdex http://www.developersdex.com *** Tag: Is there any example show how to use USB device under Compact Framework Tag: 49699

    - Changing AssemblyVersion causes TypeLoadException Dear all, I uses VB.net to create an application for WinCE 4.2. I've a "abc.dll" assemblyVersion 1.0, and a "app.exe". Initially, I've compiled my app.exe with abc.dll (version 1.0). Later, I've fixed some bugs in my abc.dll and I changed the version to 2.0. I've then copied and pasted my abc.dll into my WinCE 4.2's application folder; but when I run my app.exe I got prompted with TypeLoadException error. Can anyone please advice how I can fix this while still letting me to use AssemblyVersion to maintain my versioning scheme?

    - Newbie: MissingMethodException error with managed/unmanaged C++ Hello, I realize that MS doesn't support managed C++ on CF, but I was wondering if anyone could help a newbie out.... On the WinCE .NET Emulator, I'm running a simple C# form that calls a method inside a managed C++ class. That method uses new and delete to create and destroy an unmanaged C++ object: Code snippet in my C# form: try { Test.Managed.f(); } catch (Exception e) { MessageBox.Show(e.Message); } C++ code: namespace Test { class Unmanaged { public: Unmanaged() {} }; public __gc class Managed { public: static void f() { // This code causes a MissingMethodException in my form. Unmanaged* um = new Unmanaged(); delete um; // This code runs fine. // Unmanaged um; } }; } If I use the new/delete code in Managed.f(), I get a MissingMethodException at the function call in my C# form code. I can't even step into Managed.f() in the debugger. However, if I comment out the new/delete snippet, and instead use the code below it to create an unmanaged object on the stack, the code runs fine - no errors. I want to be able to use new and delete on a pointer - what am I missing? Any thoughts?

    - Transfering text file to workstation from PDA I have built an app in C# that runs on a PDA. This application through its course builds a text file that I must later transfer to the host computer for processing by another windows application. I know that I can do this through activesync, however, because the file could become quite large I have setup the program to store it on the storage card instead of in main memory. Specifically I would like to take the file stored on the storage card into the c:\temp folder on the main host computer if possible. At this point I would setting for getting it anywhere but if its possible I'd like to specify specifically where the file will be located. Can anyone point me in the right direction for accomplishing this task? Thanks, glenn Tag: Is there any example show how to use USB device under Compact Framework Tag: 39461

    - XmlTextReader - how do I know the name of my variable I am trying to write a simple serializer/deserializer for a set of objects/classes that I have. When I deserialize I'd like to write the actual variable name to my XML file but I don't know how to determine this at run-time. I know the standard XmlSerializer must do this because it writes the variable name and not the class. Any ideas?

    - Counting milliseconds on PPC Is there a good way to (reliably) retrieve time on Pocket PC with resolution of milliseconds? I am implementing a stopwatch using the CF, and I have tried the following: (1) System.DateTime.Now and GetSystemTime (in coredll.dll) These always return zero for milliseconds. (2) System.Environment.TickCount and GetTickCount (in coredll.dll) These give milliseconds, but API documentation indicates that they are accurate only to within 0.5 sec. Also, counting stops when the device is turned off, which is unacceptable for my application. (3) QueryPerformanceCounter (in coredll.dll) Implementation of this one is OEM-specific, and it appears to me that most manufacturers are not implementing it. Any advice will be appreciated.

So always the main form will be working in the background. After closing the second form, the first form automatically gets displayed, since i am not hiding it. Suppose I have opened the second form. So in the Memory-->Running Programs List, two applicaions with the same name are displayed.(becuase of the two opened forms). Is it a standard way?

    - Bug/restriction in RAPI Some background...We develop an application that runs on desktop computers that may or may not have ActiveSync installed. If it does, and the user also has our Pocket PC version of the application, then we provide a way for users to transfer our specific type of data file backwards and forwards between PC and Pocket PC. Works perfectly with the RAPI code in Opennetcf so long as the user has Activesync loaded on the PC. It doesn;t have to be running, and we can detect that, it just has to be loaded! RAPI requires ActiveSync to facilitate the interprocessor communication (which makes perfect sense), but we have a lot of our users who don't have a Pocket PC, and consequently won't require or use our interface...BUT...they still have access to the forms in our application that initiate and handle this file transfer. When a user enters this part of the application, the first thing we try to do is a Dim myRAPI as new RAPI statement, and our users who do not have ActiveSync may still, inadvertently, enter this part of the program. We just want to be able to detect that ActiveSync is not running or that the 'link' is not functioning and if they try to do anything, just tell them that (as we do with folks who have ActiveSync installed, but perhaps not running, or where the Pocket PC is not in the cradle). The problem is that the 'Dim' statement causes a hard and untrappable crash in the standard RAPI .dll that we use. Is there a way in VB to detect if ActiveSync is present and installed on the PC, BEFORE making any RAPI calls, declarations, etc...? Is there, for example, a particula file that is present when ActiveSync installed that we could test for? We have tried adding a bunch of try...catches, but in VB we don't know how to catch the 'inescapable exception' that gets thrown up when calling RAPI when ActiveSync is not present... Grateful thanks in advance for any thoughts, comments or ideas... Glyn Meek Tag: Is there any example show how to use USB device under Compact Framework Tag: 39375

    - How to get the current users email address from outlook on PPC We have a PPC app that generates reports and sends them out through email. We are using Alex Yakhnin's code (http://blog.opennetcf.org/ayakhnin/CategoryView.aspx?category=Send%20Email) to send email with attachments given the SMTP server. I am supplying the FROM and TO email addresses to this code. The thing is you can always specifiy someone else's email address other than the device owner in the FROM field. I would like to know if there is a way to find out the email address of the device user from Pocket Outlook so that I can populate the from field automatically without the user entering it. Any help would be appreciated. Venkat Polisetti Tag: Is there any example show how to use USB device under Compact Framework Tag: 39371

    - ListBox - How to detect a vertical scroll movement? Hi all, In CF, if a ListBox has more items in its datasource than it can display, it automatically shows a vertical scroll bar. I have a need to detect when the scroll bar has been clicked by the user, either stepped by one using the arrow or stepped by a page-full, causing the list to change. There does not seem to be any standard ListBox events in CF that let me know when the list has changed when using the scroll bar. Is there any way I can detect when either the scroll bar has been clicked or the ListBox listing has changed?

    - SE problems with storage card removal and open files I just bought a new Axim x50v and tested my application on it - spent some time to fix the disappearing toolbar icons and other minor problems. However I can not find any information regarding the following problem: 1. I open a file located on a storage card using System.IO.FileStream. 2. Remove the storage card 3. Any operation on the stream (e.g. Seek or ReadByte) will hang the program - the program never gets the control after calling Seek or ReadByte On my older (2002) device the above will throw an exception (which is the expected behavior). Here is the sample code I run (just adjust the path - use any file you want): try { System.IO.FileStream s = new System.IO.FileStream(@"\SD Card\Test.tst", System.IO.FileMode.Open, System.IO.FileAccess.Read, System.IO.FileShare.Read, 15000, false); MessageBox.Show("remove the card now"); s.ReadByte(); //or call -> s.Seek(1, System.IO.SeekOrigin.Begin); MessageBox.Show("never comes here"); } catch { MessageBox.Show("never comes here either"); } Tag: Is there any example show how to use USB device under Compact Framework Tag: 39365

    - Inconvenience using Mailto I sometimes use "Mailto:" to generate or start emails for users. All works well except when running the command, it will first open internet explorer, then it will open the mail client to create the email. I want to know why does it opens the explorer first...other ppl's such operations don't show the explorer, why should mine? Here is how I run the command, I start the "iexplore" process with the commend line like "Mailto:sampleaddress@sampledomain.com" any help appreciated.

    - volonteers wanted Hi, I have a ruggidized handheld, that came with our landsurveying equipment, running WinCe.net 4.2. The manufactor does not support writing additional software. I want to explore if it is possible to write my own data collecting routines. Normaly I should do this in Delphi but Delphi does not support CF. I've tried some demo's from NSBasic, Creativity Corp, & SywareCe, but some didn't run on my device, while others that do run don't give me full control on form layout or input-checking. I'm looking for some people that will write some simple code (an edit , some buttons, dropdown, radiobox) in MS VB to check if I can get it running on the device, this way I can check what I 'll need and what it will cost me to write my own apllications. Hardware specs: The device is a "TSCe" = Trimble Survey Controller running Windows CE.net 4.2 which is an embedded OS from Trimble & TDS (Tripod Data Systems) Intel StrongARM SA-1110, 206MHz proc 64MB low-power SDRAM 64MB non-volatile flash disk 1/4 VGA color LCD touch screen (Horizontal layout 320x240) 57 key tactile keyboard (full num & alfanum) integrated speaker & microphone multi output port (rs232 & usb) Any volunteers ? Maybe someone who wants to point my nose in the write direction? any help appreciated, Kind regards, Tag: Is there any example show how to use USB device under Compact Framework Tag: 39355

You've basically asked us "I have a tool. Give me instructions on how to
use it." Without knowing what tool you have, we've got no way to know.
What kind of USB device? A USB keyboard? It's no different than the SIP,
just handle keystrokes. A USB mouse? Handle mouse events? Serial Adapter?
Use a COM port with the virtual COM driver. A mass storage device? Use the
IO namespace just like any other file. A camera? If it has a CE driver, it
probably has an API you can P/Invoke.
