    - 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". I'm new at win 5 development, on a dell computer I installed on Win XP Home ed.SP2 < Activesync 4.1, .Net Compact Framework 2.0, VS 2005 prof.-try, win 5 - Pocket PC, Smartphone) The C# sample gives an 'System.InvalidOperationException' occurred in Microsoft.WindowsMobile.Forms.dll. 2. 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). I hope that here it will be faster responsed. Tag: Beam or Share Application Tag: 125780

    - 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.

    - OpenNETCF GPS Hi, I'm using opennetcf to try and connect my GPS. When I run the following code, I get the Opening message, then right after get the stopped. I never get a running message. I'm sure I'm using the right port and baud rate. I've tried 3rd party GPS software on my device to verify it does work. Just curious if anyone sees anything wrong with this code. Thanks so much using OpenNETCF.IO.Serial.GPS; private void button1_Click(object sender, EventArgs e) { gps.GpsSentence += new OpenNETCF.IO.Serial.GPS.GPS.GpsSentenceEventHandler(gps_GpsSentence); gps.GpsCommState += new OpenNETCF.IO.Serial.GPS.GPS.GpsCommStateEventHandler(gps_GpsCommState); OpenNETCF.IO.Serial.BaudRates br = OpenNETCF.IO.Serial.BaudRates.CBR_9600; gps.BaudRate = br; gps.ComPort = "COM4:"; gps.MinBaudRate = br; gps.MaxBaudRate = br; //gps.AutoDiscovery = true; gps.Start(); } private void gps_GpsCommState(object sender, GpsCommStateEventArgs e) { switch (e.State) { case OpenNETCF.IO.Serial.GPS.States.Opening: MessageBox.Show("GPS Opening"); break; case OpenNETCF.IO.Serial.GPS.States.Running: MessageBox.Show("GPS Started"); break; case OpenNETCF.IO.Serial.GPS.States.Stopped: MessageBox.Show("GPS Stop"); break; case OpenNETCF.IO.Serial.GPS.States.Stopping: MessageBox.Show("GPS Stopping"); break; } } Tag: Beam or Share Application Tag: 125767

    - 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.

    - Multiple forms (advanced programming, I think) Hello! I am developing an application for Pocket PC 2003 with Visual Studio 2005, C #, Compact Framework 2.0 and SQL Server CE. Well, this application needs to use different forms to display the contents of the database. In addition, these contents vary depending on what is retrieved from the database. My problem is a problem of efficiency in the execution of the application. I looked through the internet and I have not found much about this topic. Does anyone I might indicate a book about advanced programming for mobile applications? If there is a book and a web address or article or whatever, I do not care. Thanks!

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!

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).

For instance, I can set an outbound port to a remote device and send data through it (via the proper COM port in my C++ app). However, when discovering the sevices on this PPC, SPP is not reported. That means that a remote application trying to connect via SPP by first determining whether SPP is supported will not work. And that's the problem, because the Pocket PC does support SPP. It only doesn't let others know about it. Does anyone know of some setting (registry flag, API) that would force the MS BT stack to advertise SPP along the other profile it supports?

    - Canceling a download via HttpWebRequest Hi all, I have some code running on the Pocket PC (w/CF v2.0) that grabs a file (about 20 MB) from the server using HttpWebRequest. I want to give to user the possibility to cancel the download (the download method is running in another thread which is aborted when the user cancels). From what I understand, to close everything gracefully requires calling Abort() on the HttpWebRequest object and/or Close() on the WebResponse object. Failure to do so will interfere in the subsequent attempts to download the file. But here goes, calling either of the methods seems to hang the device, but in fact I think there is some cleanup going on in the backgroup. BUT, from a user point of view, it changes nothing. Is there a bug in the CF because the same code works A1 on the desktop. Has anybody been able to work around this, or am I simply missing something? Thanks. Here's a lean version of the code: private void DownloadFile() { HttpWebRequest request = null; WebResponse response = null; Stream stream = null; FileStream fs = null; try { request = (HttpWebRequest)WebRequest.Create(_remoteFileUrl); request.KeepAlive = false; response = request.GetResponse(); stream = response.GetResponseStream(); string localFilePath = Path.GetTempPath() + Path.GetFileName(_remoteFileUrl); fs = new FileStream(localFilePath, FileMode.Create); int total = 0; byte[] buffer = new byte[0x1000]; while (true) { int currentRead = stream.Read(buffer, 0, buffer.Length); total += currentRead; fs.Write(buffer, 0, currentRead); if (currentRead == 0) { break; } } } finally { fs.Close(); response.Close(); request.Abort(); } } Tag: Beam or Share Application Tag: 125602

    - RAPI being block buy Windows mobile Security model? Hi all, I have written a C# application that is to be used to commission(install and setup) Symbol HHT (Windows mobile devices) with drivers, Wifi network setting, phone settings and software. I have got the application doing all the basics like coping files, deleting files, editing the registry and running processes all using the OpenNETCF.RAPI.Communication wrapper. But the security seems to be blocking me at every turn. It all works as long as I am not using any System folders(Windows, Application) or protected Registry Keys (LocalMachine\Drivers) The problem is that these are the exact places that I need to be executing these things in order to set the devices up. The problem with doing the commissioning manually is that we often need to setup more that 1000 at a time. And doing this manually can take weeks.

The simplest method for this is to call \windows\beam.exe and pass it the
full path of your application file. This will bring up the standard beam
dialog and allow you to send via Bluetooth or IrDA.

I don't know of any mechanism to allow you to build a .cab file on the
device. If you mark your cab file as read-only when you install it it will
not be deleted so you could then find the file on the system and beam it on
to another device. I'm not sure if the file attributes are carried across
when you do this though.
