    - Video capture with preview for windows mobile 5.0 Hi, I am encountering a problem while developing an application for windows mobile ver 5.0 which capture video and take still pictures with live preview. Environment for the application: 1. We have developed a DLL in VC++ which use direct show filters graphs to capture video. The dll have 4 functions as follows: // hWnd is the handle for a message window and handlePanel is handle for a panel (container) which shall show the priview of recording) 1. InitializeGraph ( IntPtr hWnd, IntPtr handlePanel) // Capture still image and store into local folder 2. CaptureStill(); // Start record Video 3. StartCaptureVideo(); // Stop record video 4. StopCaptureVideo() 2. On the other side we have a C# application which shall call the DLL (using DllImport method) funtions. The application is working perfectly for taking still image and recording video without live preview. But when we added the code for showing preview the application hangs. Following is the code which initialize capture graph in dll. [color=red]Red marked lines are code for showing preview.[/color] // initialize capture graph HRESULT CGraphManager::CreateCaptureGraphInternal() { HRESULT hr = S_OK; CComVariant varCamName; CPropertyBag PropBag; OAEVENT oaEvent; WCHAR wzDeviceName[ MAX_PATH + 1 ]; CComPtr<IMediaEvent> pMediaEvent; CComPtr<IGraphBuilder> pFilterGraph; CComPtr<IBaseFilter> pVideoEncoder; CComPtr<IBaseFilter> pASFMultiplexer; CComPtr<IFileSinkFilter> pFileSinkFilter; CComPtr<IPersistPropertyBag> pPropertyBag; CComPtr<IDMOWrapperFilter> pWrapperFilter; CComPtr<IBaseFilter> pImageSinkFilter; CComPtr<IVideoWindow> pVideoWindow; IMediaControl *pControl = NULL; RECT rect; // // Create the capture graph builder and register the filtergraph manager. // CHK( m_pCaptureGraphBuilder.CoCreateInstance( CLSID_CaptureGraphBuilder )); CHK( pFilterGraph.CoCreateInstance( CLSID_FilterGraph )); CHK( m_pCaptureGraphBuilder->SetFiltergraph( pFilterGraph )); // // Create and initialize the video capture filter // CHK( m_pVideoCaptureFilter.CoCreateInstance( CLSID_VideoCapture )); CHK( m_pVideoCaptureFilter.QueryInterface( &pPropertyBag )); // We are loading the driver CAM1 in the video capture filter.

    - eVB Barcode Scanner Focus Distance I need to make a small tweek to the eVB code I have inherited from my predecessor that will adjust the focus distance on our Symbol PDT8146 2d Imager Scanners. The Imager Demo app that comes with the device has a combo box with these options available so I know that I can perform this modification in either eVB or eC++, but I'm not sure where to go now. Effectively, I would like something like this: If MyReader.ReaderParameters.ReaderType = Symbol.Barcode.READER_TYPE.READER_TYPE_IMAGER Then MyReader.ReaderParameters.ReaderSpecific.ImagerSpecific.FocusPosition = Symbol.Barcode.FOCUS_POSITION.FOCUS_POSITION_NEAR End If I have pored over the ScanControl documentation to no avail and sought help from Symbol, but they cannot provide very much support for this dated application.

    - Windows Mobile 5, GPRS: How to DISABLE the "Cannot connect" popup/ balloon/message ? Hi all I developed a WinMobile 5-based application that needs to open a GPRS-connection to make a webservice-call (1x every hour). By applying a "registry-hack" I managed to suppress the "Connect to GPRS..."-popup... BUT I was not able to prevent the "Cannot connect"-popup notification window, that is automatically shown by the winmobile-device when there is no avail. GSM/GPRS-signal. My questions: 1) Is there a registry-entry that can be modified to suppress the "Cannot connect"-popup? 2) Is there a way to disable/suppress the "Cannot connect"-popup by using the API? 3) I read on the web, that the only way to suppres the "Cannot connect"-popup is to *kill* the window programmatically AFTER it has been shown by the winmobile-OS... PLEASE somebody@microsoft... tell me that this is not true (;->). Thanks for your help ! Regards, MH Tag: what if Installer has requirements? Tag: 127410

    - ARM DSP Instructions in Windows Mobile 5.0 Hi, I am working on Windows Mobile Pocket PC 5.0 Emulator.I am working on Visual Studio 2005 . We are converting inline assembly to separate assembly functions and meanwhile we encountered an exception at SMULWB instruction. I got information from internet that WindowsCE doesnt support ARMv5 instructions only ARMv4.Is this true ? I found that there are ARM DSP-enhanced Intrinsic Functions like _SmulAddWLo_SW_SL are available. 1) But when i use the function in .c files,its building fine but while running in emulator throwing the following error Undefined Instruction: Thread=97529938 Proc=814c6e30 'mp3_encoder.exe' AKY=00002001 PC=00056800(mp3_encoder.exe+0x00046800) RA=00056860(mp3_encoder.exe+0x00046860) BVA=1c17f6fc FSR=00000405 Unhandled exception at 0x00056800 in mp3_encoder.exe: 0xC000001D: Illegal Instruction. The program '[57b4bc2a] mp3_encoder.exe' has exited with code 1067 (0x42b). 2) But when i use the function in .asm or .s files,its throwing linker error like " Unresolved external Symbol" what might be the problem ? 3) But when CLZ (which is a ARMv5 instruction) is replaced with _CountLeadingZeros intrinsic in assembly file(.s and .asm ),its building and running fine. i havenot seen anywhere any discussion regarding the topic in the internet. Hope experts can help me ? If nobody has faced the situation,hope Microsoft guys will look into this topic as the subject hasnot been addressed till now.

    - Problem in Using Javascript in Windows Mobile IE Hi All, We are creating some webpages for Windows Mobile using JSP. We need to capture the KeyDown events for Function keys. We were trying to achieve this with JavaScript/JScript. We were able to do this in Desktop IE. But the same code is not working in the pocket IE. The device we are using is MC70 by Symbol. We would like to know 1. If KeyDown event is supported in any version of Window Mobile IE ? 2. If yes, how can we capture it on web page ? Sample code which I used for F1 key is attached below. as stated above its working in Desktop but not in Windows mobile. <HTML> <HEAD> </HEAD> <BODY onKeyDown="alert('KeyDown: '+ window.event.keyCode)"> Version: 1.1 </BODY> </HTML> When we tried with the onload event in the body , it is working in the mobile as well. Basically, our requirement is to navigate to some other page, when the user press any Function keys. Any pointers or suggestions to achive this functionality ? Is there any document available, which describes about the supported javascript functions in PocketIE ? Thanks in advance Anoop Mob : +61 432 421 195 Tag: what if Installer has requirements?

    - Winsock Sendto() affecting receive data Hi, We have a voip application running on Win Mobile 6.0. We are sending /receiving packets of 160 bytes (20ms) . We have been having an issue with the receive data when we are simultaneously sending on the same socket. If we comment out the sendto() function the receive data is ok otherwise with the sendto() in we lose a few frames, this results in lost audio at the earpiece. we have done a lot of tests to prove the audio is fine. Simply commenting out sendto() cures the problem so we are wondering if sendto() can affect the receive data over a socket. We have set the socket to be non blocking but have noticed using QueryPerformanceCounter that sendto() is taking 5-10ms to complete. Can sendto() block in certain conditions even on a nonblocking socket? Tag: what if Installer has requirements? Tag: 127372

    - Connection Manager and Network Timeouts Hello there, I'm trying to create a persistent connection application on Windows Mobile 6. I intend for this application to use mobile radios (GPRS) to communicate with remote servers using Connection Manager for long periods of time (days). However, there appears to be a problem with my connection manager code. It appears to me that we are either getting killed by the network, or the device is timing out the session. I can't figure out which. Is there a particular set of calls to Connection Manager that need to be made to a) make a persistent connection that last days? (should I use always_on?) b) register to be notified if a connection is terminated either by Windows Mobile or the network? c) What is the event that I should be capturing to re-establish a killed connection manager handle? Right now we are attempting "Get Connection Status" before making network calls, but it doesn't seem to be working quite right. Any help appreciated! Tag: what if Installer has requirements?

    - Correct provisioning of SDK certs on WM6 for service to autostart I have a couple of Windows services that need to be signed with the priviliged certs in order to auto-start when the device boots up. I am currently using the SDK certs for development but am having problems with WM6 in that the services won't auto-start. All is fine for WM5 so I know the registry entries are ok. I have also tested a plain service sample that doesn't do anything useful and that doesn't load either on WM6. If I use the MS Security Configuration manager to provision the certs to the device then it all works but it doesn't if I just copy the two .cer files over and manually install them. Also doesn't work if I do the same with the .pfx files or copying the tool.cab file over and installing that. I know I don't have this problem with WM5.0 because I tried it on a Treo 750 before I upgraded it to WM6 so something has changed with security in WM6. As a workaround I have an app in the Startup folder that starts my services but I shouldn't have to do this. How can I find out exactly what the MS security configuration manager is doing to provision the SDK certs on the device? It doesn't seem to be just copying the tool.cab over to the device.

    - How to Register SQLITE DLL on PocketPC A friend is developing the PocketPC side of an application we are jointly working on. I am creating the Desktop side. To be able to exchange data back and forth within this application, we are using SQLITE as the database. It is working GREAT on the desktop side. And my friend is able to make it work GREAT in his development environment on his desktop. But when he sends the application over to his PocketPC, he must register the DHSQLITE.DLL file. Here is the problem. He does not have REGSRVCE.EXE on his PocketPC. Nor can we find it anywhere, where we can obtain/extract it from. We have downloaded and tried the REGSVR.EXE software, and it says it can't find the DLL file he wishes to register, which he has definitely loaded on the PocketPC. Does anyone have any solutions for us, please ? We are both stymied. Thanks in advance. (Or recommend a relational database which WILL run on both platforms, and which we can exchange datafiles between the platforms.... we have tried SQLServer....can't exchange datafiles. we have tried MSAccess.... can't run on PocketPC natively.)

    - Scaling Dynamic Controls for 640x480 Devices Hi All, I am having an issue on when or when not to scale a control that is dynamically added to a hosting User Control when executing on a device with 640x480 screen. Here is what I got... In designer, if a developer defines a property, my code will dynamically add a control to the main hosting control (everything works great; even scaling). I think this works because the control was added during the initialization process which the OS tells it to scale (at this time its a part of the controls collection of the host). Now, the problem is if the developer does not use designer, but uses the LoadForm event to define the property, my control is dynamically added but its not scaled correctly for the 640x480 device. I think this happens because it was added after the hosting control's initialization. Any ideas on how to handle this? I am using Visual Studio 2005 Framework 2.X and such. Thanks in Advance!

    - Precision problem with eVC++ 4.0 Hi, I am having a problem with the CString's Format & the wsprintf command in eVC++ v4.0 when displaying "double" values. I have some "double" values in my database and need to display them to as many decimal places as possible. Some of the values have values of 10 or more decimal places, and .Net can successfully write & read them to my "SQL Server Mobile" database to this precision. The problem is, in eVC++, if I use the %f parameter, it doesn't display enough decimal places (it typically rounds them up/down to just 4 or 5 decimal places). However, if I ask Format/wsprintf to display the values to a large number of decimal places, then it "corrupts" many the values adding .00000000001 to their value. For example: CString str1, str2; double doubleValue = 1.28533; str1.Format(_T("%f"), doubleValue ); str2.Format(_T("%.19f"), doubleValue ); Output: str1 = "1.285330" str2 = "1.2853300000000001000" I do appreciate that floats can't store decimal values exactly (1/3 being the typical example) but I find it strange that my .Net CF app can read & write the values successfully, without adding any 0's at the end (like str1 above) or adding or subtracting a tiny discrepency to their values, but eVC++ fails miserably. The irony is that if I use Microsoft's Query Analyzer to view the values in my table, it displays them perfectly. That "1.28533" value does appear in Query Analyzer as "1.28533", and all other figures appear fine, albeit rounded to about 8 decimal places. Any suggestions...?

    - Only digits in text box Hi, I want to create edit field that accepts only digits. I added ES_NUMBER style during creation. The problem exists concerning Fn key on some HTC and Symbol devices. So you can't enter digits without pressing Fn key. If you don't press Fn you hear beep and nothing is put in the edit field. I tried enabling InputMode functionality it for PPC but it doesn't work. I tried to test using ImmEscape functions to set Number InputMode, but again that work fine with SmartPhone but failed in case of PPC. The another way to do this would be char mapping but again that will be different for different device ( e.g on LW "E" maps to "1" and on Wizard "Q" maps to "1"), then this we have to maintain on device.ini.

    - Deployment Question Here's what I got: I have a User Control that is in its own .dll that optional uses another control that is in another .dll. The problem that I have is when I run my Sample code, I get an error about the control in the 2nd .dll cannot be found. I looked on the device, the .dll is not deployed. How do I get the 2nd .dll to be deployed with the other .dll? I am using VS2005. The User Control references the other control by project references. Everything builds and installs, but the 2nd .dll is not deployed when running the sample code. I know its on the machine, because it shows in the designer. I just need to tell the deployment to a device to always include this 2nd .dll. Thank you in advance for your help! Tag: what if Installer has requirements? Tag: 127294

I've got an app that requires .NET CF 2.0, SQL Mobile 2005, and SQL Client 2.0.

If I place my installer on the local network for our employees to get, how
can I make it so that they also automatically install the requirements?

Should I bundle these requirements into my Installer? They might not need
them!

Bundling the required installers into your installer would probably be the
sure-fire way to make sure they get installed--if they're already on the
device, it won't hurt anything for them to be re-installed. If you decide to
go that direction and you're not familiar with common techniques to launch
other installation packages from within your custom installation package,
reply back, and I (or others) can provide some more help.

Alternatively, of course, you could just put the required installation
packages in the same shared location as your installation package and
instruct users on required installation order.
