    - How to get character set category of mail body on CrossBow I write a mail reader application to show message to user on CorssBow. And I use PR_BODY_A and PR_BODY_HTML_A property of MAPI to retrieve mail body. My application is running smoothly in the past, however I found it has some problem on newly CrossBow version. MAPI will translate mail body into UTF-8 format automatically in the past. But it don't work now, I has to translate character set by myself, but I don't know how to get the character set of body? Please give me some suggestion. Tag: InvalidCastException Tag: 120502

    - Autoupdate/Liveupdate I'm currently writing a PocketPC application with C# and SQL Compact 2005 that requires autoupdate/liveupdate functionality. My thinking right now is that I would like the app to be updated when the user cradles their PocketPC. Somehow ActiveSync would sync up the application and the database via updates downloaded from our servers (running SQL Server 2005 + WinServer 2003) to the users host PC. Unfortunately I've never done anything like this before and am not really sure where to start. I would imagine I would need some sort of WinXP app to facilitate this update via ActiveSync? Thanks for any help. Tag: InvalidCastException Tag: 120500

    - Unable to create new subscription Hi, all, I'm using SQL Server 2005 Developer Edition and Pocket PC Phone emulator, anonymous access. My program has been working (replicating/synchronizing) perfectly one day and next day would just crash. I've been at it for this past two months and the same thing happens: it will work just fine...next day it gives me the "request to IIS" error. I've given Firewall exceptions to the SQL Server, SQL Server Agent and browser instances. I've configured the SQL Server Surface Area. Done the read/write permissions for IUSR_* account for the virtual web folder and snapshot folders. What else haven't I done? Ah, yes... haven't slept at all! Right now, everything I do gives me this error: "A request to send data to computer running IIS has failed..." which means I can't do anything and I need to make a presentation of this thing sometime next week. (And, oh, yes..it was working perfectly last night when I turned off my computer!) Should I just tell clients not to use Pocket PCs for field work to enter data? I know I'd get this done sometime today... and I know it's going to randomly crash on me again. And I know I won't be able to sleep again tonight...Sigh. Has Microsoft found the answer why this is happening? Anybody? Marilyn Tag: InvalidCastException Tag: 120489

    - Beginning PocketPC Database Development Hi, I'm looking for resources to get me started developing a database app for the Pocket PC (Windows Mobile 5.0) I would be developing using the CF 2.0, probably utilising a SQL Server DB as the backend. But that's about as far as I've got! Before being hit with a myriad of options, for example: SQL Server CE on the Pocket PC - how does this sync with the main SQL Server DB running on the server? Can I use SQL Express? What are the data access components available to me? Is ADO still a valid technology in this environment? What about ActiveSync? How do you get it to synchronise data with your database? As you can see, I'm very much a novice to this environment, and would really appreciate a few pointers to get me started.

    - SHLoadImageFile problems. Alternative? I have a routine that loads images onto the screen of my Pocket PC. Some files have been converted to bitmaps so that they could be embedded into the resource file, but most of these are JPEG files that reside on the disk in a special folder. For the embedded bitmaps, I use LoadBitmap with the MAKEINTRESOURCE macro. For JPEG files on disk, SHLoadImageFile loads images from paths stored in a CStringList. After images are loaded, StretchBlt is used to paint the images to the screen. Both techniques succeed and produce no errors; however, I am finding that calls to SHLoadImageFile consistently destroys other components. First, I had a CRect object that stored the GetWindowRect results from the same procedure that I called SHLoadImageFile. The dimensions of CRect went from defined endpoints to random numbers after the call to SHLoadImageFile. I solved this problem by moving my CRect object outside of my image loading class and passing the value into it. Now, after I call the method that includes the SHLoadImageFile, the files in the CStringList are being whipped out - and the CStringList is not even in the same class as the SHLoadImageFile routine. Has anyone else had any problems with SHLoadImageFile? Is there an alternative to loading JPEG images? I am coding with eVC4. Thanks for the help, Joe Tag: InvalidCastException Tag: 120474

    - More Bluetooth anomalies I wonder if any of you experienced BT guys can shed any light on this ... I have given up on the Vodafone v1640 because it doesn't actually work, as I suspected. The BT problems are unique to that machine. I have told them but they are not listening. I have given up on Symbian because the development system doesn't actually work. I have told them but they are not listening. I have laid my hands on a MS stack BT device (a datalogic Jet) which DOES work, however it's configuration utility for BT is strange, even though it's CE5. There doesn't seem to be any way it will let you publish the serial over BT service, even though it works fine with incoming. It appears to use COM5 for both incoming and outgoing serial comms. Is this common, or should I look for (yet) another device? TIA Unc Tag: InvalidCastException Tag: 120473

I got it working with the CameraCaptureDialog but this interface is too complicated for the users of the application. I understood that if I want my own interface I need to use DirectShow or use C++ and use the API. I'm not a C++ programmer and I never worked with or used DirectShow.

    - CeGetFileTime "Access Denied" on Pocket PC 2002, but okay on WM5 I am writing a Pocket PC installer (in Visual Studio 2005) which is working really well in Windows Mobile 5, but when I used the installer to target a Pocket PC 2002 device, RAPI's CeGetFileTime returned 0 (signaling an error) which CeGetLastError says was a code 5 error (Access Denied). I tried waiting in the debugger before letting CeGetFileTime execute, but it didn't change anything. I've been opening, writing, and closing files over the RAPI connection. What access could I lack that CeFetFileTime needs? Any suggestions would be appreciated... -Mike http://pnmx.com/ Tag: InvalidCastException Tag: 120372

    - Setup.exe install problem on WM6 device (but CAB install works) i have a (signed) CAB file that installs without any problem or warning on the WM6 Standard emulators (i.e. Smartphone). This CAB file uses the following line in the Platform section of the .inf file: PlatformMax=5.9 which indicates that it should support all devices up to WinCE 5.9 (WM6 is 5.2). indeed it also install fine on WM5 Smartphones. But when I install this CAB file via a desktop Setup.exe file, i get the following error on the desktop: "APPLICATION XXX does not support the connected device type. Application Manager will make the application available for installation when a supported device type is connected". This very same setup.exe file has no problem installing this CAB on a WM5 device or emulator. Since the CAB file is compatible with WM6 Smartphones, why would the setup file refise to install it on the WM6 Smartphone emulator? i can provide the setup file if someone is interested.

    - WM6 CAB Installer ignores PlatformMax? it seems that the WM6 CAB Installer ignores PlatformMax in the Platform section of CabWiz .inf files (used by the /platform option of cabwiz.exe). see http://msdn2.microsoft.com/en-us/library/aa924318.aspx i have a CAB with PlatformMax=5.9 , and it installs with no warning on the WM6 Pocket PC emulator. is that a known bug / feature? this, i think, could make it much harder to have a setup installer with two CAB's, one for WM5 and one for WM6, in case thise would be necessary.

    - 3G and GPRS I'm looking for a way to determine the network type I'm using. I need to distinguish between a 3G network (UTMS) and a normal GPRS connection. I've tried to lineGetGPRSClass, but I get the same value for both networks. I've also tried to call RasGetLinkStatistics, but dwBps is 28800 for a 3G network. I'm using Windows Mobile 5. Thanks in advance. Tag: InvalidCastException Tag: 120356

    - Bluetooth COM Port - TX/RX My device uses COM5 for incoming data and COM6 for outgoing data. To establish a serial connection using CreateFile, do I need to call CreateFile using READ_ONLY for COM5 (incoming) and call CreateFile again using WRITE_ONLY for COM6? EX: hReadPort = CreateFile(_T("COM5:"), READ_ONLY, ...); hWritePort = CreateFile(_T("COM6:"), WRITE_ONLY, ...); Also, for serial connection tools, do I need to call them for each port? SetCommState(hReadPort, ...); SetCommState(hWritePort, ...); SetupComm(hReadPort, ...); SetupComm(hWritePort, ...); SetCommTimeouts(hReadPort, ...); SetCommTimeouts(hWritePort, ...); My port doesn't want to talk to me, and I'm thinking this might be my problem. Could someone correct me or confirm what I'm thinking? Thanks for the help, Joe Tag: InvalidCastException Tag: 120354

    - Volume reduction on Incomming call Windows Mobile reduces the volume of any playing sounds on the device when an incomming call arrives, even if the ringtone is set to none. Is there a workaround for this default behaviour. My application needs play a voice alert on incoming calls. This will work as a ringtone and so the normal ringtone is set to none. But the application plays the sound in too low volume that it is bearly audible. Any solutions/suggestions ? Tag: InvalidCastException Tag: 120347

    - WMDC & RAPI.DLL Hello, my application use the rapi.dll and works fine under XP/AS. My pseudo-code for testing: void test() { CeRapiInit(); CeRapiUninit(); } Under XP/AS works fine. If drop the device from cable and reconnect the device then i can call my testfunction and it works fine. Under Vista/WMDC want run this function only one. The secound call get a error C00...005 (!) in line of CeRapiUninit. Ok, now i remove this line and test again. At XP/AS works fine, but all CeXXX function failed on reconnect. Solution: i call CeRapiUninit -> CeRapiInit -> CeXXX -> works fine. At Vista, i do the same, but all CeXXX function failed ! CeRapiUninit do nothing !(???). My second problem are, how can i register my sync-dll at WMDC ? ( made with VC6.0 ). The registry-keys are different for AS/WMDC ...*arg* :-( Do i need VS2005 and WM SDK 6 for create a Vista/WMDC sync-dll ? Regards, Martin sorry for my little bit english.

    - Windows mobile 6 migration issue Hi, I have created a simple program, which zooms the screen using Stretchblt function. It worked fine with Windows mobile 5 device. But When I tried to test it in Windows mobile 6 device, it is not working as intended. Stretchblt function is not working properly. It is not zooming the screen. Please let me know if i need to do something to make it work in WM6. The code is as given below. iZoomLevel = 2; m_MemDc.CreateCompatibleDC(pDC); //Create bitmap object m_hOldBitMap = (HBITMAP)m_bmpScreen.CreateCompatibleBitmap( pDC,iZoomLevel*m_iWidth,iZoomLevel*m_iHeight); SelectObject(m_MemDc,m_bmpScreen); //Stretch the image and paint it on the screen m_MemDc.BitBlt(0,0,iZoomLevel*m_iWidth,iZoomLevel*m_iHeight,pDC,0,0- m_iCaptionHeight,SRCCOPY); pDC->StretchBlt(0,0,iZoomLevel*m_iWidth, iZoomLevel*m_iHeight, &m_MemDc, 0,0 ,m_iWidth,m_iHeight,SRCCOPY); I am using WM5 SDK only.

Hi.

lNr is an integer column in table Lestur.
Why is this OK:
SqlCeCommand cmd =
new SqlCeCommand("SELECT Count(*) FROM Lestur", Conn);
Int32 nCount = (Int32)cmd.ExecuteScalar();

but this:
SqlCeCommand cmd =
new SqlCeCommand("SELECT MAX(lNr) FROM Lestur", Conn);
Int32 nMax = (Int32)cmd.ExecuteScalar();

returns InvalidCastException?

Regards,
Gudni
