 - Determine when Scrollbar is tapped in datagrid control Happy New Year, I can not seem to figure out how to determine when a scroll bar is tapped from within a datagrid control. My problem is that when the user taps a cell I reposition a text box over the cell and allow them to edit its contents. However, when the user taps the scroll bar, my textbox is no longer covering the appropriate cell. I can I determine when the datagrid scrolls so I can hide my textbox or reposition it accordingly? Thanks for any help. Tag: Databases & Pocket PC Development Tag: 71124

 - 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: Databases & Pocket PC Development Tag: 71110

 - GPSboy and the PC2002 emulator HI, I have been trying to use the program GPSboy on the emulator for PC2002. When I hit the Icon, I get an error. It says, "can't find pvbDecl.dll". I found it on my PC ans copied it to the windows file on the emulator using the export function of the remote veiwer. I still have the problem, and when I open the windows file I don't see it on the emulator but it is clearly there on the remote veiwer. (I tested another txt file and it is visible on the emulator.) Why is the emulator not finding the pvbDecl.dll and why won't the emulator make it visible. Thank you such much for your help Pat Tag: Databases & Pocket PC Development Tag: 71107

 - 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!

I created AdviseSink object and use Advise() as follows: m_lpMAPIFolderAdviseSink = new CMAPITableAdviseSink(m_pSession); hr = m_pMsgStore->Advise(0, 0, fnevNewMail | fnevObjectCreated | fnevObjectDeleted | fnevObjectModified | fnevObjectMoved| fnevObjectCopied | fnevStatusObjectModified, m_lpMAPIFolderAdviseSink,&connection); The operation is sucessfull. The problem is that no notification is received when I manually create a new message, copy/delete, etc. If I copy messages using MAPI, for example, m_pOutBoxFolder->CopyMessages(&EntryList, 0, m_pSentItemsFolder, 0, 0, 0); the notofication is received! I suppose the context in which advise sink object run, should be changed, or something. Can anybody help? Thanks. Tag: Databases & Pocket PC Development Tag: 71023

 - exception handling and COM/ATL/RTTI Greetings, I'm trying to port a COM object to PocketPC using Embedded Visual C++ and the PocketPC SDK. The COM object makes ample use of try/catch exception handling. It compiles fine but I get the following link error: StdAfx.obj : error LNK2019: unresolved external symbol "void __stdcall `eh vector destructor iterator'(void *,unsigned int,int,void (__thiscall*)(void *))" (??_M@YGXPAXIHP6EX0@Z@Z) referenced in function "public: void * __thiscall ATL::CComTypeInfoH older::stringdispid::`vector deleting destructor'(unsigned int)" (??_Estringdispid@CComTypeInfoHolder@ATL@@QAEPAXI@Z) After doing some reading I believe this is a problem with RTTI support, yes? I found a patch from Entrek Software that fixes this for ARM but I'd really like to be able to do some work in the emulator. Is there an official fix from Microsoft that includes emulator support, or plans for a fix? Thanks, Mike Stangel Tag: Databases & Pocket PC Development Tag: 71019

 - CAB Files not downloading in Pocket Explorer Hello, I am writing an application for PPC that will need to be distributed remotely. My users have wireless Symbol scanners running Pocket PC 2003. I create the CAB files in .NET and have placed them on a web site. The problem is that when surfing to them with Internet Explorer from the pocket pc devices, they are opened as 'web pages' with garbled text, instead of being downloaded as files which can be installed. What am I doing wrong? Thanks, dave Tag: Databases & Pocket PC Development Tag: 71017

 - problem with pxlcnv.dll i'm developing a general purpose conversion utility for converting between the pocket pc formats and the desktop formats (ie: pocket excel to desktop excel). I've gotten the word conversion to work, but i'm having trouble with the pocket excel to desktop excel. I've tried both the excel 5.0/95 and the excel 97/2000 conversions. Neither are working, but the 5.0 seems to be not working less than the 97. With the 5.0 it is writing all the data correctly, but isn't writing the document summery. With the 97, its just FUBAR's everything, excel isn't even able to repair it much less get any of the necessary data out of it. does anybody have any ideas on this? thanks, edward Tag: Databases & Pocket PC Development Tag: 71016

 - Some news about Windows Mobile 2004? Does anyone have some clues about the new Windows Mobile version aka Pocket PC 2004. - Main features (includes support for VGA screens?) - date of release. I've been told that the 2003 version was a "transition" version ans that the 2004 will be a major version. Still true? Regards Tag: Databases & Pocket PC Development Tag: 71014

 - Retrieve Control Name I am new to developing on the Pocket PC platform. I am using Visual Studio 2003. My problem is that I can not seem to figure out how to retrieve the control's name (id) that I assigned it. I need to retrieve it becuase I am populating a SQL insert statement by looping through the textbox controls and using the textbox name and text. In asp.net I would simply use myTextBox.id. How do I do this in vb.net for the pocket pc? Any help will be appreciated. Thanks in advance. Tag: Databases & Pocket PC Development Tag: 71010

I'm new to Pocket PC development.
Just wondering how to develop a smart device app'n and use
the controls from the data tab on the toolbox (ie to
connect to a database). It seems when I use the smart
device app'n template, none of the data controls are
enabled.
How do you connect to a database?

Eileen,

You have to connect the controls to the data in your code in the current
version of Visual Studio.
