    - Development environments Hi all, I am a newbie on Pocket PC programming. I have been doing quite a bit of research recently and have a few questions. I was going to write in .NET (probably C#) as I have good knowledge of this in an ASP.NET environment. However, reading vaious forums suggests that this is quite slow compared to native code using Visual C++ (eVC++) I have downloaded eVC++ and after about 4 days, managed to get a working hello world app running. (Things missing, hardly any getting started guides on the net and other stuff... I downloaded MANY MBs of different software to get it going.) So, here is what I want to do. I am concerned about the speed, hence the reason I am looking at eVC, but as I don't have any background experience in C++, will probably struggle to get anywhere. eMbedded Visual Tools comes with visual basic as well as C++. Would VB built with eVB also be faster than .NET? Are there any eVC programming tutorials around that will help me to get to grips with the language? (for example, step by step to creating some simple applications, the step by step being suitable for a newbie. I have yet to find anything.) Can eVC and eVB easily communicate with .NET webservices? Ultimately, I will also want to communicate directly with the inbuilt phone hardware / software, such as communicating with the RIL and getting the IMEI information. I know that .NET cannot connect to the RIL properly. Parts of the app I want to build could be done in .NET, others in C++. Is there easy ways of communicating, for example, if I were to write a C++ app that contacted the RIL, could I get the C# app to talk to my C++ app to get the information? I will probably have many more questions, but these will help me to make an informed decision as to which way I should go. Aside from these, your advice would probably be useful. -- Best regards, Dave Colliver. http://www.AshfieldFOCUS.com ~~ http://www.FOCUSPortals.com - Local franchises available Tag: Audio Recorder C# Tag: 125800

    - Dialog suddenly become maximized. Why? I have MFC based project, which run on HP iPAQ PDA under Windows Mobile 5. I've created custom message box modal dialog for my application with child style. The dialog has variable number of custom buttons, some of which are hidden. The m_bFullScreen variable always set to FALSE. I have very strange behavior. Sometimes when I click on button (or any other area of dialog) , the dialog become maximized. In this case its corresponded OnButton handler is not even called. The second click on the same button closes the dialog. Can anyone comment on this very strange behavior of the dialog?

    - How to get a command bar in my today item's dialog Hi group I've already written some small apps, some with quite a number of dialogs and they all got their own menu. Now I'm working on a today plugin which has an own options dialog. My problem: I set it up to show the dialog when I tap on its area on the today screen. But then the dialog has no command bar, thus no SIP as well. But when I open the dialog through Settings->Today->Items there is such a bar with a SIP. Could you please tell me what I'm doing wrong? I'd like to get a commandbar which provides a SIP to enter settings. Following is an excerpt from my options dialog procedure. I use the same code in my other apps (that is, in dialogs that are opened within the apps), where it works. Is there something evidently wrong here? case WM_INITDIALOG: SHINITDLGINFO shidi; shidi.dwMask=SHIDIM_FLAGS; shidi.hDlg=hDlg; // hDlg comes from function interface shidi.dwFlags=SHIDIF_DONEBUTTON | SHIDIF_SIZEDLGFULLSCREEN; SHInitDialog(&shidi); hwndCB=CreateRpCommandBar(hDlg,IDM_OPTIONS); hMenu=(HMENU)SendMessage(hwndCB,SHCMBM_GETMENU,(WPARAM)0,(LPARAM)0); break; hwndCB and hMenu are defined within the function as a static HWND and HMENU, respectively. The menu resource IDM_OPTIONS exists, of course ;-) The only difference I can think of is that in my other apps I have an own main window which already brings along a commandbar in which the dialog's menu is placed, whereas a today item's "main window" is embedded in the today screen and therefore doesn't have that bar. I'd apreciate any helpful answers. -- Gruß | Greetings | Qapla' Quoting can be so easy: http://www.netmeister.org/news/learn2quote.html Tag: Audio Recorder C# Tag: 125789

    - Microsoft Mobile Internet Toolkit Hi, I'm starting to use ASP.NET mobile controls, and I read that I should download the Microsoft Mobile Internet Toolkit (http://www.microsoft.com/downloads/details.aspx?familyid=ae597f21-b8e4-416e-a28f-b124f41f9768&displaylang=en). When I started running the setup it said that it might overwrite existing files, and since the date on the download page was Jan 2002, I'm worried that it will overwrite things like .NET Compact Framework or WM5 or PPC2003 SDK files. Does anyone know if the Internet Toolkit is included in later downloads, or if there is a later safer version to install, or what files may be overwritten? Any info would be greatly appreciated. Thanks for any help, Steve Tag: Audio Recorder C# Tag: 125788

    - PPC vSP You would think there would be some GUI consistency I am trying to build an application which behaves as similarly as possible on SP & PPC. Microsoft suggest that you use common code where possible. I create a simple spinner as in this example. http://msdn2.microsoft.com/en-us/library/aa457782.aspx#example_spinboxcontrol It works fine cycling through the items on VK_LEFT/VK_RIGHT and tabbing on VK_DOWN Have I been able to get the same functionality on a PPC ? No way. If anyone has been able to do so I would appreciate a code snippet (native win32). Thanks PS I think *they* thought that anyone with a touch screen device will only want to use the touchscreen. But this is NOT the case. It is often more convenient to use the keybaord/Nav controls as shortcuts. Tag: Audio Recorder C# Tag: 125787

    - error 0x80070002 mobile development - camera Hi, I am using Visual Studio 2005 with win 5 PC Pocket and Smartphone Emulators. 1. The CeCamera C api code sample in the emulators gives the error: "An unknown error: 0x80070002 occurred". I have no idea how to fix it. The SHCameraCapture function returns an "E_ACCESSDENIED" or "The system cannot find the file specified".

Can I use for example the videocap sample for both pcpocket and smartphone.? I tested with the emulators, it goes... But in the readme of the sample is specified that it requires pc pocket sdk. I can't go further with the development. Please help. Thanks. PS. I posted this question also to the msdn forum, smart devices development (mative c api development).

    - MoveWindow causes problems under WM50 MoveWindow API causes the "A problem has occurred with gwes.exe" error for me under the both PPC WM50 Emulator and real device. At the same time the MoveWindow changes the target window size as it should to and it looks like everything works ok except of the gwes error popped. The parameters passed to the MoveWindow looks like correct. Below is a cut from source code: ------------------------------------------------------------------------------------------- SHMENUBARINFO mbi; RECT rc, rcMenuBar; // Create the window const TCHAR* name = _T("Dummy"); hwndMainFrame = CreateWindow((const TCHAR*)mainFrameClass.classAtom, name, //WS_CAPTION | WS_SYSMENU | WS_THICKFRAME | WS_MINIMIZEBOX, WS_SYSMENU, CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, NULL, NULL, mainFrameClass.instance, this); if (!hwndMainFrame) { throw rdr::SystemException("unable to create MainClient window instance", GetLastError()); } memset(&mbi, 0, sizeof(SHMENUBARINFO)); mbi.cbSize = sizeof(SHMENUBARINFO); mbi.hwndParent = hwndMainFrame; mbi.nToolBarId = IDR_MENU; mbi.hInstRes = ::GetModuleHandle(NULL); if (!::SHCreateMenuBar(&mbi)) { throw rdr::SystemException("unable to create menu bar", GetLastError()); } m_hMenu = mbi.hwndMB; ::ShowWindow(m_hMenu, SW_HIDE); ::ShowWindow(hwndMainFrame, SW_HIDE); GetWindowRect(hwndMainFrame, &rc); GetWindowRect(m_hMenu, &rcMenuBar); rc.bottom -= (rcMenuBar.bottom - rcMenuBar.top); // The following MoveWindow caused the gwes error !!!!!!!!!!!!!!!!!!!! ::MoveWindow(hwndMainFrame, rc.left, rc.top, rc.right - rc.left, rc.bottom - rc.top, FALSE) ------------------------------------------------------------------------------------------ Once the MoveWindow is commented out everything works with no errors. Visual Studio Debugger doesn't stop when the error is popping. The Application Verifier gives nothing regarding the error. Is there any way to fix the problem, please? Many thanks.

    - keybd_event wont fire KeyDown event for VK_Return keycode on textbox? Hi all, I am working with C# CF2 on windows mobile 5 phone edition on a Symbol MC70 device. For some reason the KeyDown Event doesn't fire when you use the keybd_event to send the VK_Return= 0x0D. If I use the hard keyboard Return I get. KeyDown KeyPress KeyUp KeyUp If I use the soft keyboard Return or keybd_event and VK_Return I get. KeyPress KeyUp If I use any of the three above methods (Soft keyboard, Hard keyboard or keybd_event) to input Numbers, letters or even Delete then I get. KeyDown KeyPress KeyUp Which is what I would have expected from all of these scenarios. I have tried setting the Textbox allow returns property and it had no effect. I have also tried setting the form key preview property to see if that would make any difference. This is the only post I have been able to find that even resembles my problem, it is for the desktyop and it is the richtextcontrol, but I don't really understand what the resolution to the problem was. http://www.thescripts.com/forum/thread249414.html I really need to be able to send the VK_Return using keybd_event and have it fire the Key Down event. Any idea on how this can be done? I have already tried moving my code that is running in the KeyDown to the KeyUp but this has not been an acceptable solution to the problem as it introduces to many bugs. I have attached the code I have used for testing to the bottom of this post I create all the controls dynamically so all that you need to do to test is start a new single form project and past all this code over the top of your form class code. The way to test is uncomment lines from the textBox1_GotFocus event.

    - Custom Today item not showing up in Today settings (very weird) Hi all, I've developed a WM5+ custom Today screen item, using Visual Studio 2005 and the WM6 SDK. The problem is that some people report of being unable to find my custom item in their Today settings. It simply doesn't show up in the list at all. They have already checked the registry references put there by the CAB installer (which I also made) and these are correct. To debug that, i've made another tester app that tries to load the DLL file (using LoadLibrary, so no static reference) but EVEN this tester app fails to load altogether, with a generic "untrusted app or component not found" error. The two files (tester exe and dll) were started as simple projects, no MFC, ATL or other dependencies. The joke is that other people report that my custom item is working flawlessly!

I tried creating a recurring appointment (on desktop Outlook), which occurs every Thursday (1 Nov, 8 Nov, 15 Nov...) I then changed the time of the 8 Nov one (selected "Open this occurrence") to 7 Nov. So the appointment now occurs on 1 Nov, 7 Nov, 15 Nov... However, when I check it using OutlookSession.Appointment.Items[x].RecurrencePattern.GetOccurrence(date), The appointment looks like it still occurs on the 1st, 8th and 15th. GetOccurrence(7 nov) returns null. How do I get the new (modified) occurrences of the appointment? Is there a better way than using GetOccurrence() for each day in the year? Thank you in advance.

But this did not work for me either. I have found some other threads, but with no solution. The one solution I can think of is to detect BTH stack in the device and call appropriate functions. Is this possible? If so, how one can do it? During the search I found some solutions how to turn wifi on/off via SetDevicePower function. Can this approach be used for BTH?

However, when I run the same code on the M700, I get "an unknown error occurred" with no detail when I call "cameraCapture.ShowDialog()" Any help would be appreciated. Thanks Mike Tag: Audio Recorder C# Tag: 125634

    - BUG Report: MFC's ON_WM_WININICHANGE() causes incorrect actions on I don't know if Microsoft's people are watching this thread or not, but anyway ... Symptom: If the derived class CMainFrame maps the WM_WININICHANGE message, the software-based input panel (SIP) would be activated (pulled up) after a dialog box closes and focus returns to the main frame. Environment: Windows Mobile 6 Classic Emulator, Visual Studio 2005, Windows XP Professional Steps: 1. Create a new MFC application for smart devices. SDK: "Pocket PC 2003"; Application Type: "Single document with DocList". 2. In the message map of CMainFrame, add a line "ON_WM_WININICHANGE()" 3. Define and declare the function: void CMainFrame::OnWinIniChange(LPCTSTR psz) { CFrameWnd::OnWinIniChange(psz); } 4. Now run this application under WinMo Emulator. 5. Call up the About dialog box, while it's showing on screen, activate (pull up) the SIP. 6. OK the dialog box and back to frame window. At this time, you will see the SIP is deactivated (hidden), this is correct. 7. Call up the About dialog box again, you will see the SIP is still deactivated. Don't do anything, just OK it. Result: After you're back to the main window, the SIP is activated (pulled up). Expected Result: After you're back to the main window, the SIP remains in the deactivated (hidden) state. ---------------- This post is a suggestion for Microsoft, and Microsoft responds to the suggestions with the most votes.
