    - Serial communication questions I managed to open a RAW IR port on ipaq 3950, it works on and even manage to control my HITACHI TV with it, however there are some quirks: 1. the output signal i am sending seems (on a digital scope) to have some unexpected data along with the signal, i think its from the flow-control or buffer sizes, what is the right way to open a port without(!) flow control at all? 2. i am trying to "listen" to incomming ir signals, with success but the timing of the thread seems to vary from time to time, like the ipaq is spanning to a different process and then returns, this means the timing is not accurate at all, how can i use a thread that has ALL cpu power? i tried some time critical threads but with no luck. thanks for the future replies ;-) -- Liran www.com-n-sense.com Tag: technical question about ppc Tag: 71184

    - How to use wireless to debug my app? I'm getting quite frustrated. I've been developing an app for iPaq using the cradle and USB for debugging. Slow as it is it works. Now, since my app requires serial port access, I need to move my debugging to via wireless so I can have my serial port cable hooked up. However, I am lost as to how to set this up. I've read on Google where many people highly recommend this setup but can't find any info on exactly how to make it work. As of right now my iPAQ can detect and "connect" to the wireless lan but can't see the Internet. I'm not sure if it can see the PC and, even if it could, I have no clue as to how to start a debug session in eVC over the wireless link to run my app on the iPAQ. Can some post a HOWTO link or give me some step-by-step directions, please? I'd be forever grateful. Feel free to dumb it down - I'm a PocketPC newbie. I'm using eVC 4, ActiveSync 3.7.1, PocketPC 4.20.1081 on WinXP on an iPAQ 4155. Thanks, Chris Tag: technical question about ppc Tag: 71178

    - Pocket PPC 2003 CD I have upgraded my viewsonic from pocketpc 2002 to pocketpc2003. When I tried to read my e-books with the reader, I got the message that Microsoft Reader could no longer access the book. I downloaded the version 2.2 from Microsoft and now I can read my e-books again. Seems to me that the new Microsoft Reader that comes with PocketPC2003 does not contain the latest MS Reader. Has anybody else upgraded from pocket pc 2002 to pocket 2003 and can not read e-books? Lamar Tag: technical question about ppc Tag: 71175

    - WMP control for PIE can't play secure WMA on PPC2003 I am developing a WMA player to play secure WMA's on PocketPC using eVC3.0 & the Windows Media Player for Pocket PC Software Development Kit. I am able to use the WMP control for PocketIE to play regular as well as secure WMA's( transfered to PPC2002 using desktop WMP9) on PPC2002. The player is also able to play regular WMA's on PPC2003. My problem is the player cannot play secure WMA's on PPC2003. When using this WMA player on the new iPaq h1935 running PocketPC2003 w/WMP9, I notice the following: 1. I can still transfer secure WMA's onto the device w/desktop WMP9. It creates a DRMv1PM file at the root of the device, or the root of the Storage Card(SD Card). 2. I can also transfer using a WMDM app. It also creates a DRMv1PM file. 3. The PPC2003's WMP9 is able to play the secure WMA transfered via 1 & 2.. 4. The MS sample app from the "Windows Media Player for Pocket PC Software Development Kit "does not play the secure WMA's anymore. It says "Windows Media Player cannot play this file because the file cannot be found or the file type is not valid. Verify that the network and proxy settings are correct...." I have noticed that quite a few postings in this and other newsgroup: 1. There was issue about PIE unable to display content using the WMP control in PPC2003. 2. There was problems playing legally purchased WMA's. I assume these are secure WMA's. My questions are: 1. Are there any ways to get the WMP control to play secure WMA's on PPC2003? Is there any sample/documentation about this issue? 2. When can we have an updated WMP control that works on PPC2003? So far everything else seems to work fine on PPC2003 with the current WMP control SDK except the WMA's w/ DRM. Thanks! Joseph Serenade Systems, Inc Tag: technical question about ppc Tag: 71169

    - eVB Run Time and deployment I have created an application with eVB 3.0 and created a setup package with Application Install Wizard. I copied the whole CD1 folder to Pocket PC. On Pocket PC, I clicked on the file TestApp.Arm 1100 (4K) v3.00.CAB and the application was installed. When I tried to run the application, I got the message that the application requires MS eVB Runtime to install. What are the eVB runtime files? I can see Pvbform2.dll, Pvbhost2.dll and vbscript.dll in the Windows folder from my PC when Pocket PC is connected to my PC. I am totally new to Pocket PC development. How can an eVB application be deployed to Pocket PC. Thank you for any advice. Tag: technical question about ppc Tag: 71162

    - Copying files to emulator Hi, I am using EVC3 to develop my app, but I am slowly going crazy copying files to the emulator using the Windows CE remote file viewer. I need 30 small data files copied across each time I test my app, but the remote file viewer only allows one file to be copied at a time, one cannot select multiple files. This must be the most braindead piece of software ever written. There does not seem to be a command line tool capable of copying files to the emulator, if there was, life would be simple. Someone suggested that I could add the files to my project, and they would be copied to the emulator automatically with my exe, however try as I may, I cannot figure out how to do this. PLEASE, somone tell me how I can get my data files copied to the emulator, before I go absolutely crazy!! Thanks, Allen Tag: technical question about ppc Tag: 71110

    - CryptoAPI and PPC Signature Application I am using VS .Net 2003 to develop an VB.net Pocket PC application which encrypts connection string information for a SQL Server Database. I have copied the Crypto Class code from the Pocket PC Signiture Application Sample into my project (http://msdn.microsoft.com/mobility/understanding/articles/ default.aspx?pull=/library/en- us/dnnetcomp/html/ppcsignatureapp.asp). I can not get the text I send it, to be decrypted. I error out with an 'unhandled exception'. One thing I notice is that I get different hProv, hHash, and hKey values when running the CryptoSvc2.Decrypt function versus the CryptoSvc1.Encrypt function (this may be correct, I don't know). The following is my code: Dim EncryptString As String Dim DecryptString As String Dim CodedArray() As Byte Dim EncryptArray As Byte() Dim DecryptArray As Byte() Dim CryptoSvc1 As New PEdgeCF.Security.Crypto CodedArray = System.Text.Encoding.ASCII.GetBytes("AnyText") EncryptArray = CryptoSvc1.Encrypt("123456789", CodedArray) EncryptString = System.Text.Encoding.ASCII.GetChars _ (EncryptArray) MsgBox("Encrypted Data: " & EncryptString) Dim CryptoSvc2 As New PEdgeCF.Security.Crypto CodedArray = System.Text.Encoding.ASCII.GetBytes _ (EncryptString) DecryptArray = CryptoSvc2.Decrypt("123456789", CodedArray) DecryptString = System.Text.Encoding.ASCII.GetChars _ (DecryptArray) MsgBox("Decrypted Data: " & DecryptString) Any help would be greatly appreciated!! .

    - PocketPC and Windows CE.NET Hi, I'm an experienced developer, but on standard PC's I am interested to start developing for Pocket PC, but I have some issues I need to clarify. I'll appreciate any answer to my questions 1. What is the difference between PocketPC 2003-2003 and Windows CE.NET? Is it a different OS? Or just the name for Compact NET Framework for PPC? 2. What is the difference between embedded Visual Tools 3.0 and 4.0? 3. What is the best way to go for developing PPC applications? Using eVC/eVB or using Compact Net Framework? 4. Is Compact Net Framework available for old PPC (PPC2002, PPC2000, Windows CE OS)? 5. I'm interested to buy a PPC to test the applications on it, but first I might be interested to test them under an emulator. Is any emulator available? Where can download it? I want to be able to test the application on my development PC before deploying them on PPC. Any other suggestions and links to web pages providing startup information for developers about PPC will be greatly appreciated. Happy New Year to all of you!

Dear Sir,

I have never used this means before, but found the name of the newsgroup
under windowsmobile newsgroups. So I thought maybe someone there can help me
out. I'm looking for a place where I can find technical information being a
little more deeper than the average ppc2000 user. For instance, I would like
to know if it is possible to auto-synchronize a folder on my ppc- SD-Card
through ActiveSync (or any other tool). So that my main memory doesn't have
to be used. Or, If I want to get all my appointment from Calendar
automatically backed-up, I keep getting the message 'backup Region is full'.
Can anyone help me to find answers on these and similar questions?
