• Gurbhajan filecache

  Can anyone tell me something about the filecache I haven't found any detailed example code regarding the filecache. So in what cases do I have to preload files Especially how is this preloading done Do I have to enter something in the manifest or playlist My recommendation is to keep the ACA file and reference it as a resource in the playlist (ApplicationResource for instance). Also, reference it as a resource in your manifest to prevent the application from executing until the resource is loaded in the file cache. Once you do this, you should be able to use the URI to the file within the ACA w/o doing any FileIO copy magic. The reason why I want to copy it is because I am planning to update thi ...Show All

• Ed Santosusso DMOs Operability in Media Foundation ?

  I thought I remembered hearing somewhere that DirectX Media Objects could be directly used by Media Foundation. However reading the current docs for Media Foundataion Transforms ( http://windowssdk.msdn.microsoft.com/en-us/library/ms703138.aspx ), it sounds as if you can implement IMediaObject on an object that implements IMFTransform but one cannot directly use DMOs in Media Foundation. Is this correct Thanks! Scott Hi Scott, You're right: The Media Foundation pipeline is prepared to handle Media Foundation Transforms (MFTs), not DMOs. And you're also right that if you write a wrapper for the DMO that you want to use that translates IMFTransform calls to IMediaObject calls, you should be good t ...Show All

• Marleen What is the best way to implement the UI for author mode

  Hi, I found it's rather painful to build the UI for author mode, especially when I need to align the controls, or many fancy stuffs. Currently, I am using the method that I think the most simple one that I know: p_elSource.innerHTML = "<table style='width:100%'><tr><td>Url</td><td style='width:100%'><input id='myInput' value=''></td><tr></table>"; var myInput = document.getElementById('myInput'); Above is the simple one but there is a problem here: getElementById is not a good approach as some people mention (especially when add 2 same gadget on the web page). And I also encountered some problem in sizing. Can you share your experience to build a robust UI but less painful Th ...Show All

• gregg100 Question about style:opacity behavior

  Hi, According to chapter 7.6.3.3.2.41 of specification, style:opacity is applied to content elements. Exact description is the following: “The opacity property is used to determine how to blend the background color and marks of areas produced by an element with the current composite rendering.” HDiSim (ver. 061005-0100) doesn’t apply style:opacity to text – text is always opaque. At the same time opacity is applied to style:border . Should style:opacity be applied to text element in the following example Should style:opacity be applied to border What about " marks of areas ", what does it mean < div id =" Div1 " style:backgroundColor =" blue " style:opacity =" 0.2 " style:x =&qu ...Show All

• Tilfried Weissenberger SideBar Gadget and <object /> Tags

  I assume that SIdebar is using a mini-IE7 window to display themselves, but I can't seem to get an <object /> tag to work in my gadget. Any idea why that wouldn't work Before I spin my wheels understanding what is happening, I wanted to make sure that there wasn't a security prohibition to using an <object /> or a <embed /> tag. WPF/E is just a subset of WPF that's cross-platform/cross-browser. Running them though an IFrame does work. Referencing external files will not work. Quoting Brian from the Sidebar Dev team: " Samples that access external files will not be able to access those files. This includes images referenced in the XAML and XAML files, even inside the gadget package. This is not a securit ...Show All

• Ajay Suri Determining 64-bit OS

  I have an app which reads from the registry to look for some registry keys written by a 32-bit app. When run on 64bit windows, the registry entries are under Wow6432Node. How do I determine if the user is running 64-bit windows. Thanks Dan Check the "PROCESSOR_ARCHITECTURE" environment variable. If it's not "x86" it's 64 bit. I think the valid values are "AMD64", "x64" and "IA64" (obviously not relevant to Vista) You can do an IsWow64Process api call to see. typedef BOOL (WINAPI *LPFN_ISWOW64PROCESS) (HANDLE, PBOOL); BOOL IsWow64() { BOOL bIsWow64 = FALSE; // assume 32 bit // can't call IsWow64Pro ...Show All

• BubbaHasty Using gadget from a 3rd party place.

  Hi! I have a gadget, that Ii don't want to send to the live gallery, but I'd like to use it on live.com from different machines (home, work). And I don't want to install web server on each of these PCs, and use the gadget from localhost. So i want to put it on a web server I can reach from both places. But when I try to add the gadget manifest's URL on the live.com with my web server's ip I get an error: "checking for autodiscover tag..." and then nothing happens. Yes, I read an explanation for that. (Besides I tried also with IE6, but got the same problem.) But if there is a work-around in the gadget SDK to handle the 'cross-domain limitations of the XmlHttpRequest' , why can't the live.com make the gadget addition in this way ...Show All

• Saeed Ahmad MFT help

  I'm trying to create an MFT for Windows Media Player 11, based on the GrayScale sample in the SDK. The problem is in the ProcessOutput method. I'm unable to "Lock" the input buffer; it works fine on the output buffer. hr = pIn->QueryInterface(IID_IMF2DBuffer, (void**)&pIn2D); if (SUCCEEDED(hr)) { ::OutputDebugString("input buffer: 2D\n"); hr = pIn2D->Lock2D(&pSrc, &lSrcStride); } else if (hr == E_NOINTERFACE) { hr = pIn->Lock(&pSrc, 0, 0); lSrcStride = lStrideIfContiguous; //assert (cb == m_cbImageSize); } The first QI returns E_NOINTERFACE and the attempt to call Lock on pIn results in E_NOTIMPL. If I check the size of the input buffer, it's zero -- is this normal ...Show All

Am I missing something in this process..Please suggest... Thanks Once you've enabled debugging support for IE (see above) and restarted IE (again, see above), there'll be a new menu option called "Script Debugger" under the View menu. Inside the "Script Debugger" submenu, you're given the option to "Open" or "Break at Next Statement". "Open" will prompt you to open a new debugger or attach an existing session.

• Howard Pinsley How to set and call titleEvent and ChapterEvent?

  I followed the spec example (Z.6) and put a titleEndHandler(evt) in my script file. And added EventListener (addEventListener("title_end", titleEndHandler, false) on top of my script file. But after my title play through, the event is not called. I thought the event should automatically fired. Do I need to do anything on the playlist too Also make sure it is a PlaylistApplication -- if it is a title application it will probably be shut down before the end event is fired. The event is automatically fired when you leave the title - either by playing through to the end or jumping into a new title. How are you confirming that your titleEndHandler function isn't being triggered Have you adde ...Show All

• jcnconnect NamedNodeMap Interface ( usage guidelines)

  Hi everbody The DOM Level 2 Spec (page 44) defines NamedNodeMap Interface but it does not give a method to create a NamedNodeMap. So the only use of NamedNodemap is through the Node interface where we have a member variable : NamedNodeMap atributes; ie the attributes belonging to a node can be assumed to be stored in a NamedNodeMap. ------------------- The questions are : 1. Does all the attributes (specified or non-specified(ie those having default values)) belong to a node's NamedNodeMap 2 . The NamedNodeMap Interface has method item() (Refer Page 44 DOM Level 2 Core Specification ). Quoting the spec : The item() returns the indexth item in the map.If index is greater than or equal to number of nodes in the map ,this returns NULL ...Show All

• dev_bih How to output 2 streams into evr

  Hi, all: I know EVR can mix two streams into a single frame. But when I create such topology and call start, I get a error code: MF_E_TOPO_UNSUPPORTED. So I have two questions: 1) How to create such topology about mixing multi-streams into a single evr 2) Due to async programming style, it is hard to find out which step cause error. Is there any way to know the details when I get a error code from the Invoke function Thanks. Although you are correct that the EVR does support multiple streams of input, the Media Foundation pipeline does not support this EVR feature in Vista. Therefore, I'd guess that your error stems from the fact that Media Foundation is trying to connect both of your inputs to the same EVR stream and is get ...Show All

• Nightman28 Can gadget read data from Excel file?
