    - CE Query Analyzer Please Help! Hi, I am having a frustrating problem with SQL CE query analyzer. I cannot add a NOT NULL column to an existing table, using either the GUI or an SQL statement "ALTER TABLE Sites ADD status bit NOT NULL". I tried the same with all my existing tables, and with different data types, and no luck. I can only add these columns when I originally design the table. All my tables have PKs and are empty. Is this a bug or is it supposed to operate this way? I really don't want to re-create all my tables just to add one non-nullable column to each. Any help would be GREATLY appreciated.

    - Symbol PDT 8100 Cold boot. Hi all, I am trying to persist .NET Compact Framework(a cab file), two other third party softwares on a Symbol PDT 8100/Windows Mobile 2003 across cold boots. My problem is that the Flash File System(\Application and \Platform folders) on the device is way less than what I need. I have added a compact flash card to the device. Copied all three cab files(.NET CF and two third party softwares) to the compact flash card. Wrote a .CPY file which would tell the Operating System to copy the CAB files from Compact Flash card to "\Windows\Startup". This is not working. How can I persist three softwares across cold boots if the space on the Flash File System is less and the Compact Flash card method does not work? Can I somehow increase the memory for the Flash File System? Any ideas would be much Appreciated. Thanks in Advance, KriS. If at all the Tag: How to Determine whether a pocket pc is VGA mode or not.

    - Help! Is something fundamentally wrong with this? Hi All, I created a new ActiveX project, implemented IObjectSafety, and then tried to create a modeless dialog in the ActiveX control's InitInstance. Then, I made a web page that embeds it and then open the web-page: It <seems> to work at first, but then weird problems arise. When the device is cradled/uncradled, Pocket IE shuts down. Not only that, but certain Pocket PC's lose their cookies too! Also, if ShowWindow( SW_SHOW ) is not used after creation, then Pocket IE hangs up, and the control terminates unexpectedly. I need the dialog to be modeless so I can use it to hold state information, and only appear when necessary. I have a win32 version that runs just fine on the desktop machine. Is there something fundamentally wrong with doing this? Thank You! Bryan Palmer Software Engineer TORO - EICON Tag: How to Determine whether a pocket pc is VGA mode or not. Tag: 91681

    - Using RDP / Terminal Server with CE.NET L.S., I have been trying to write a Terminal Server Client-application for Mobile 2003 using Visual Studio.Net. In VB.NET for desktop, I can use the MsRDPClient-control through which I can start a session, and use Virtual Channels. However, for a Pocket PC, the compact framework doesn't seem to be able to implement the same control (an OCX), because the compact framework doesn't accept COM. Nevertheless, the Microsoft website suggests that use of the MSTsCax.dll with the compact framework is possible. eg: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wcerdp/html/cerefimstscaxeventsinterface.asp But, no clue as to how to import or register this control. Simply adding is not enough. Does anybody know how do this? Or does anybody know for a fact that it is not possible? Much obliged, Joris Broeren Tag: How to Determine whether a pocket pc is VGA mode or not. Tag: 91676

    - How to change IMM mode with external keyboard? Hello. My customers have pocketpc 2003 korean version and 3rd party external keyboard. But problem exists. Because customers use korean language, they may have to change IMM input mode-korean or english input mode. On the screen, there is toggle button. But I can't find the any external keyboard input for that - somthing like kor/eng toggle button. For windows, there is kor/eng toggle button, and it works. If adequate keyboard driver which is provided by MS is selected, we can change the input mode by pressing "Shift + Space". For the external keyboard, there is no kor/eng button, so I'd like to emulate the button using something like "Shift+Space" or any other key. I also tested kor/eng button in my PC keyboard using PPC emulator, and it doesn't work. I must find the way for customers...so I've tried to make some program. At the first time, I think about keyboard hooking and luckily there is hidden function in PocketPC 2003. And I wrote down the code below. ----------------------------------------------------- hLibrary = LoadLibrary(L"coredll.dll"); if(hLibrary == NULL) { return 0; } else { m_pfSetWindowsHook = (SetWindowsHookExW)GetProcAddress(hLibrary, L"SetWindowsHookExW"); if(m_pfSetWindowsHook == NULL) { return 0; } else { HHOOK gHook = m_pfSetWindowsHook(WH_KEYBOARD_LL, (HOOKPROC) MainWndProc, hInstance, 0); } } ------------------------------------------------------- The hooking seems to works but not perfectly. Because I can get the keyboard messages but the wparam and lparam value is fixed and meaningless. How to get the keyboard information precisely? And I'd like know how to toggle the IMM input mode. For my experience, the IMM input mode is set for the applications respectively. How to change the IMM for the currently activated program, not the helper program(what I want to make). I think Pocket PC 2003 OS must support the kor/eng toggle key. If you know any work-around such as using hot-key or others, please let me know that. Thank you.

    - Software protection/Device Serial Number can it be spoofed ? Hi all We have spent around 18 months developing software for a PPC and an add-on piece of hardware. We would like to be able to 'hire out' the solution without a member of office staff. Having invested so much time and effort in developing the software and add-on hardware with the maufacturer. We want to make it 'impossible' for someone to simple copy the software and buy the hardware ! I was thinking of combining several things to make it all but impossible to run on another device. A registry entry, machine serial number and possibly a hidden file. Ultimateley what ever I do someone can just do a full backup to an SD card and load it onto the same model PPC. My main point is that is it 'easy' for someone to change a given device's serial number ? or spoof it so the program thinks it's running on the original machine ? Is it copied into the registry for IOCTL_HAL_GET_DEVICEID to read ? Thanks in advance for any assistance Andrew Kennard Tag: How to Determine whether a pocket pc is VGA mode or not. Tag: 91666

    - Using COM port on HP iPAQ 1710. I want to make a program for my Pocket PC that can send/recive data(512B) to/from a MCU through the COM1 port (serial port). I am using Microsoft eMbedded Visual C++ 4.0 with Microsoft Pocket PC 2003 SDK (emulator) to make the program on the PPC. I am also making the program om the MCU, so I conroll both programs. Here is what I want the program on the Pocet PC to do: -Open the COM port -Send data to MCU -Recive data from MCU -Close COM port Do you think that it is ok to only use the Rx and Tx lines? Does anyone know what RS232 Standard the HP use, and what voltage it operate with. I don't want to use hardware handshaking. I thinking of making a rutine in the program to check that the data is sent/received correct. Is this possible? Is there any trap I can go into? I am thankful for all kind of tip and help!

I had installed eVC4.00 + sp2/3 + PPC SDK 2003, and made some apps for my DELL PDA. But last week My computer was updated from net. Then I could not build my apps since then. Then I removeds and reinstalled eVC4.00 + sp2/3 + PPC SDK 2003 several times. The result is the same. I can't find WCE PPC 2003 App / WCE PPC 2003 MFC App in the File->New->Projects Tab, and my old apps can't be successfully compiled. But with WS2003 I can still use the PPC2003 emulator.

    - IR and UART Hello, I am working on an IR remote but I have a few questions about the hardware involved and IR (raw) in general. My understanding of the UART is this: o All serial data goes through the UART. There is no way around this since it is the last step before actually sending the data out through the serial port. o The UART will automatically append start, stop and parity bits when sending and remove them on incoming data. This is invisible to the user and causes no problems assuming both sender and receiver use UART. o The data in transit is not the actual bit representation of the data but is in fact the data plus the UART bits. â?¢ Does all IR data go through the UART? I assume it does since itâ??s a serial device but I am not sure. â?¢ Can I get around the UART either by disabling it or just bypassing it all together? I do not want it to â??helpâ?? me in any way. I want to send out a specific byte without any UART bits. â?¢ If I am receiving an IR code from a remote the data received is not the actual data sent. This is due to two things: (1) the UART has already handled the data and removed the bits it thought were start, stop and parity; and (2) if the UART is waiting for a start bit and one never comes, then the UART will continue waiting for a start bit and ignore the data it receives. This is my general conception of how the UART works. I know this is probably flawed in a few areas but thatâ??s why I am posting here. Please correct me and share any good resources that would help me get a better understanding of how IR communications work. Now, hereâ??re some general IR questions and ones related to the remote. I am using VITOâ??s Oscilloscope to view the IR code from the remote as well as viewing any bytes I send. â?¢ One finding is that if I send 0x0B VITO receives 0xF6 o FIRE BYTE: 0x0B = 00001011 = |____|Â¯|_|Â¯Â¯| o SENT BYTE: 0xF6 = 11110110 = |Â¯Â¯Â¯Â¯|_|Â¯|__| â?¢ I saw something along these lines in an IrDA doc as well. Does anyone have any information on creating an IR remote? I know devices without a CIR LED arenâ??t designed to function as such but I still would like any input you can provide. However, the first step is understanding the UART and how the data is handled. Thank you, Kyle Tag: How to Determine whether a pocket pc is VGA mode or not. Tag: 91654

    - How can I set timezone info. on PPC? Hi, all. I am trying to set timezone programmatically. First, I get the timezoneinformation through POOM, IPOutlookApp::GetTimezoneInformationFromIndex. By this way, I can get the "TIME_ZONE_INFORMATION" structure filled with timezone info. Next, "SetTimeZoneInformaton()" API is used for setting timezone. But, It is seem that some timezone info missed. If set the timezone GMT+8 Taipei(index : 220) and excute ppc clock on today screen, we can see the GMT+8 Beijing(index : 210). my code like this, ... hr = CoCreateInstance(CLSID_Application, NULL, CLSCTX_INPROC_SERVER, IID_IPOutlookApp, (LPVOID*)&g_polApp); if(FAILED(hr)) return FALSE; hr = g_polApp->Logon(NULL); if(FAILED(hr)) return FALSE; g_polApp->GetTimeZoneInformationFromIndex(220, &tzinfo); g_polApp->SysFreeString(pwszVersion); SetTimeZoneInformation(&tzinfo); g_polApp->Logoff(); g_polApp->Release(); How can I set the all timezoneinformation right? thanks.

I changed to deploy and get the System.NotSupportedException message. I ALSO get the error when I run in debug mode with F5 (not CTRL-F5).

    - Persistent installation I have programmed a pocketpc (HP/iPaq 2210) to operate as a controller for some electronic test equipment. The problem I have is that if the battery goes flat on the iPaq it loses its application. I have the installation stored on the non-volatile memory area, and can re-install, but then the installation erases itself. Can I get the installation to NOT erase itself after installation, or can I run the application from the non-volatile area? Can someone give me a pointer here?

    - COMM Ports on Windows Mobile 2003 Second Edition Hi all, I have an HP4700 running on Windows Mobile 2003 Second Edition. I am running a couple tests on my COM ports and I currently have the following information that I get from the registry: Port Registry Path Description COM1 Drivers/BuiltIn/Serial "Serial Cable on COM1:" COM2 Drivers/BuiltIn/Serial_FIR "Infrared Port" COM3 Drivers/BuiltIn/IrComm "Infrared Port" COM4 Drivers/Buildin/Serial_BTUR COM5 Drivers/BuiltIn/Serial5 "Bluetooth Serial Port COM5:" COM8 Drivers/BuiltIn/Serial8 "Bluetooth Serial Port COM8:" COM9 Drivers/BuiltIn/SerialUSB "Serial on USB" When I run the test with Bluetooth enabled, ports COM2 and COM4 fail. Why would these ports fail if Bluetooth uses COM5 and COM8? When I run the test with Bluetooth disabled, ports COM2, COM5 and COM8 fail. If port COM5 and COM8 are Bluetooth and Bluetooth is disabled, how can they fail saying that they are in use? Do I have the wrong mapping for the ports? Any help is appreciated. Thanks in advance. -- Anderson Tag: How to Determine whether a pocket pc is VGA mode or not. Tag: 91581

    - Header File compile time problems Hello, I am using EVC4 with the pocketpc 2003 SDK. When I try to compile a set of c files that I have added to the Source Files for a workspace that I have set up, I get a lot of errors in the include files that came with the pocketPC 2003 SDK. Im assuming that I have not set up the project or EVC4 correctly. I have tried creating the project as a WCE ppc 2003 application, targeted for the WCE ARMV4 and win32 emulator, as an empty project, simple windows CE application and a typical hello world application. Compiling the Typical Hello World app worked fine, before I added my C files. Here are some examples of the errors/warnings I get, any pointers anyone has would be greatly appreciated, I have not used VC/VS or EVC before. Thanks!

Hi there,
I am trying to find the screen resolution of the pocket pc, it works
fine with GetSystemMetrics() API for Non-VGA mode but For VGA mode it
displays the same resolution as Non-VGA. Is there a way to know whether
a pocket pc is in VGA mode or Non-VGA mode.

Any Reply is welcome .

Hi,

While an application is not HDPI aware, all API calls will return QDPI
values (240 * 320).
Add in your application HI_RES_AWARE resource.
For the more information see
