    - Documentation on dropped features in WinMo? Hi, I don't want to sound like whining, but a few days into the developement of WinMo app, I find the most frustrating thing is the lack of documentation on features that were supported in Win32 but dropped in WinMo. For example, owner draw combo boxes and list boxes (hmmmm... not sure, but seems to be so). I can't seem to find it but I believe there's got to be a document telling me which features were dropped from Win32. Can anyone help? Thanks. Tag: Internet connection Tag: 122726

    - Backing up Geotrust Code Signing Certs I signed up with Geotrust last year to do M2M code signing, and all was well for a while. Then just recently, I tried to do another code signing and found that the Administrative Cert (the one known only by Geotrust) was no longer on my computer. I was unable to download the Cert again from Geotrust until I had contacted them and explained my situation. Then then enabled another download for me. I must have done a system restore at some point and accidentally gotten rid of that Geotrust Cert. But that got me thinking, why not back up the Cert? Well, I tried, but I found that the Geotrust Administrative Ceritificate is marked so that the private part of the key is not exportable. But I would need the private part of the key too in order to re-import that Cert. Is there any way of protecting against a system crash? Or am I forever at the mercy of Geotrust to rescue me if I loose my Cert? Robert Scott Ypsilanti, Michigan Tag: Internet connection Tag: 122718

    - Remove particular call from non answered calls list Hi all, I've just implemented a simple filter to block some imcoming calls from a specified caller ID. After the unwanted call is intercepted, blocked and dropped (using lineDrop() function), a new "call no responded" item appears in the list of all the missing calls. Is there a way to avoid this? What I mean is if there is a way to avoid to insert this specific call in the list of all the missing ones, or alternatively to remove from the list. I would like the user doesn't understand he received a call from a certain number... Thanks you in advance Marco Tag: Internet connection Tag: 122692

    - Always on pattern ? Hi, In one of our applications, we have a long process that can take up to 10 minutes. During this time, I don't want the device to enter sleep mode.

    - doreandersample has been called but nothing Hi: I was not experience with dshow filter. I had register the dshow filter which inheritates from CBaseRenderer,and the code is from Gary Daniel The only thing I know that is if I want to get the sample from the camera,then implement the code of Dorendersample function. as I know dorendersamle will be called automatically when the graph from pause to run. I have add the following code to the dorendersample function to test: if(pMediaSample==NULL) return S_FALSE; else { pMediaSample->GetPointer(&pbData); int l =pMediaSample->GetActualDataLength(); int *m_pCopyBuffer = new int[l]; if(pbData!=NULL) { pMediaSample->GetMediaType(&mt); m_pCopyBuffer[0]=2; FILE *fp; fopen("\\618.txt","w"); fwrite(m_pCopyBuffer,1,1,fp); fclose(fp); return S_OK; } else return S_FALSE; } after the graph run, I can get a 618.txt in my folder.but when I open the .txt there is nothing. the reason of the code above is that I want to test if I get the pointer. I want to use CopyMemory(buffer,pbData,l), then I can use the data in buffer to do some image processing works. is there something wrong? and I have add the code to the CGraphManager::CreateCaptureGraphInternal in the CameraCapture.sln CHK( pFilterGraph->AddFilter( gr,L"SampleGrabber")); CHK( m_pCaptureGraphBuilder->RenderStream( &PIN_CATEGORY_STILL, &MEDIATYPE_Video, m_pVideoCaptureFilter, NULL, gr )); IEnumPins *pEnum = NULL; IPin *pPin = 0; AM_MEDIA_TYPE pmt; m_pVideoCaptureFilter->EnumPins(&pEnum); while (pEnum->Next(1, &pPin, NULL) == S_OK) { PIN_DIRECTION ThisPinDir; pPin->QueryDirection(&ThisPinDir); if (ThisPinDir == PINDIR_OUTPUT) { IPin *pTmp = 0; hr = pPin->ConnectedTo(&pTmp); if (SUCCEEDED(hr)) { pTmp->Release(); pPin->ConnectionMediaType(&pmt); } } } I can get the mediatype: major type:Video, subtype:RGB565,formattype:video_info and fix size with 38400 and 50688 38400=160*120*2 50688 = 176*144*2 is there anyone could give me some advise.

    - Decoding WMV on Windows CE 5.0 Hi, I've read a bunch of other posts, confirming my observation that on Windows CE 5.0 we only have an MP3 Decoder DMO and WMV *Encoder* DMO. This goes in hand with my inability to load WMV files with IGraphBuilder::RenderFile. So, my questions are: 1. My final goal is to decode a single (thumbnail) frame from a video file (which WMP supports). Is there a WMP API to do it? 2. Surprisingly I could load AVI files with IGraphBuilder::RenderFile, even though AVI files don't have a DMO, so maybe I can construct a WMV pipeline as well by using some component manually? -- (If I could, then writing an output filter to dump frames to image files would be easy.) Thanks. P.S. In the Windows CE Multimedia Blog, I've seen references to "WMVideo & MPEG4 Decoder DMO" but I'm guessing this is something new with Windows CE 6.0. Tag: Internet connection Tag: 122667

    - Behaviour of SetTimer I call SetTimer from my application to create a timer, which calls a callback function when it elapses. However I have discovered that the callback function is only evoked when either my application is the active thread, or when the active thread is changed (such as when a new program is opened, or a program is closed). When my program is running in the background and another thread is active, the callback function of the timer is not evoked, even after the timed has elapsed. Is there any way around this problem?

    - Porting a WinXP-DLL to WinCe Hello, I need to send data via USB host port on my Acer N30 with a program running on the PDA (no PC connected). I found libusb on http://libusb-win32.sourceforge.net for generic USB access. A C#-Wrapper is available. The libusb puts a libusb0.dll in Windows/System32 on my desktop PC, while the C#-Wrapper is in the Framework directory. Before I spend hours testing, I assume that using the very same libusb0.dll doesn't work on the ARM-CPU of the PocketPC because it's hardware dependent and the C#-Wrapper isn't. Do I need to re-compile libusb? Which Compiler can do that? I have Visual Studio 2005, but cannot find any other CPU-Option than x86 and x64. Can eMbedded Visual Tools do that?

    - Signing corporate applications .. problem again Hi, According one of my previous post, I have to add certificates to stores in the device using an autorun.exe. using this autorun.exe, I added a custom corporate certificate in the Root, CA, SPC, Unpriviledge and Priviledge stores (not sure if all are required). Later in the execution of the autorun.exe process, I run wceload.exe /silent /noaskdest /delete 0 "mycabfile.cab" in order to deploy the app. This cab file is signed with the certificate that is added in the stores. However, when the wceload.exe command is ran, nothing happen and the ExitCode result of this execution is 0x80070005. If I manually execute the cab file, I get the warning prompt about the not-known publisher. If I accept to install the cab file here, and I run the autorun.exe again, the file installs this time, the exit code is 0 (ok). Theses clues let me think that even if my certificate is in the correct stores, it is still not recognized correctly... Does anyone have an idea how can I correct this ?

    - C# Callback for RegistryNotifyCallback not working I have implemented a P/Invoke call in C# to RegistryNotifyCallback. Currently, the handle from the function is returning and the call seems to be successful, but the callback function is never firing. I have almost certainly made a mistake somewhere along the line and am hoping that someone can assist. The import is the following: [DllImport("aygshell.dll", EntryPoint = "RegistryNotifyCallback")] private static extern IntPtr CERegistryNotifyCallback (IntPtr hKey, string pszSubKey, string pszValueName, REGISTRYNOTIFYCALLBACK pfnRegistryNotifyCallback, uint dwUserData, ref NOTIFICATIONCONDITION pCondition, ref IntPtr phNotify); Some of the necessary items are: private const long TEMP_LONG = -2147483646; private IntPtr SN_PHONERADIOOFF_ROOT = new IntPtr(TEMP_LONG); private string SN_PHONERADIOOFF_PATH = ""; private string SN_PHONERADIOOFF_VALUE = "test"; public static REGISTRYNOTIFYCALLBACK Callback; I am aware that I may have set up the SN_PHONERADIOOFF_ROOT incorrectly, but I cannot find an example anywhere to confirm what I have done above. The call itself is the following: Callback = new REGISTRYNOTIFYCALLBACK(ConnectionCallback); NOTIFICATIONCONDITION nc = new NOTIFICATIONCONDITION(); // Create the notification hResult = CERegistryNotifyCallback(SN_PHONERADIOOFF_ROOT, SN_PHONERADIOOFF_PATH, SN_PHONERADIOOFF_VALUE, Callback, 0, ref nc, ref hNotify); if (hResult.ToInt64() != S_OK || hNotify == IntPtr.Zero) { MessageBox.Show("Error creating callback: hResult = " + hResult.ToString() + " hNotify = " + hNotify.ToString()); return; } The hResult is returning 0 and the hNotify is being set, but the callback never occurs. The rest of the stuff should be ok. If anyone can confirm or correct the above information, I would be grateful. I actually want it to monitor the connection state (and I do know where to find that) but I figured I would start by setting a test DWORD variable in the registry and see if I could get it to work with that.

    - Windows Mobile and MAPI We use MAPI to read inboxes on email services configured in Windows Messaging. This works fine for POP3 mailboxes, but when attempting to use it with the "Outlook E-mail" service, the IMAPISession- >OpenMsgStore call fails. Has anyone come across anything similar.

    - How the built-in word completion works? Hi all, I am developing a program that does something depending on a character just before the caret. For example, if letter 'a' is before the caret, it should display a list of "About", "After", "Assume" etc. The program I am writing is a keyboard hook, so it is intended to process with any edit control in any application. Now I have a difficulty about getting the character. I am using EM_GETSEL to get the position of the caret, but there is no message for me to get the character. I only have the index of the character, so I have to get all text from it by using WM_GETTEXT, but it is not a good idea if they contain very many letters. I just want to get a special small range of the letters for not consuming much memory and cpu time. I found that the built-in word completion works smoothly for this thing, so there must be some other way to do the same thing, but I don't know how it works. Can anybody help me with my problems? Thanks in advance. Tag: Internet connection Tag: 122585
