    - Launch the CD burning wizard from code, in Vista I need support for cd burning in my software, so I tried a couple of code samples using IMAPI, but It does not work on every Vista machine I tried. It seems to be a solution to copy the files to burn to the staging area, and then launch the burning wizard. So my question is that how can I lunch the CD burning wizard from C# code in Vista Tag: DirectShow Development Directshow : to create hotspot within video. Software Development for Windows Vista

    - GetSystemMetrics( SM_CXPADDEDBORDER ); Hey! I'm upgrading a Win2K/XP MFC/Win32 (no .NET) application to give it a more modern look and feel when running in Vista. I use Visual Studio 2005 C++ and have the February 2003 Platform SDK loaded. The application uses a CDialogBar derived class with an override added for CalcDynamicLayout() so that the dialog bar will always take up all available vertical or horizontal space in the main frame depending on its orientation. The calculation to figure out how much space is available is off by the new border padding used by the Aero theme so the dialog bar is getting cut off on the right side. If I could just get my hands on the size of that border padding, I could subtract it out and get the correct available size. After digging on MSDN, I found that the GetSystemMetrics() call was updated for Vista, providing a new index, SM_CXPADDEDBORDER, to get that size. Since I have the Feb 2003 SDK loaded, SM_CXPADDEDBORDER isn't defined so I added my own #define to set it to 92, which is the number shown in the documentation on http://msdn2.microsoft.com/en-us/library/ms724385.aspx . The DLL involved is user32.dll. The documentation also states that if the function fails, the return value is 0. My problem is that I'm ALWAYS getting 0, even when running on Vista. I would have thought that the user32.dll supplied with Vista should support this call. Has anyone else run into this Anyone have any clues or suggestions Thanks!

    - IMAPI v1 Shim source code 1. IMAPIv1 does not support DVDs period. Whether it is using the original IMAPIv1 on XP or the shim on top of Vista's IMAPIv2. We assume IMAPIv1 applications were developped without DVD in mind thus introducing DVD underneath them with the shim would be risking regressions in these applications. 2. SetActiveDiscRecorder will validate it can write to the disc by testing if either it is blank or if an import file system succeeds. If both fail, it is not a disc that may be mastered. You should be able to easily do the same in your application. Then for writing using Live File System, you may simply use regular file access api from Win32 api.

    - Workflow Tracking performance issue Thanks for your reply. Actually, I've considered the option of adjusting the tracking profile so that I don't have that much data in the workflow events table. First, I'm not sure I won't need the persist and unloaded track points, they help in tracking what happened to the instance. Second, I have only two instances being tracked in the database, there's an indexed table with 25000 records, and a couple of joins performed over that data, does it have to be so slow What if I have dozens or hundreds of instances being tracked in the database I might change the tracking profile to minimize even more the quantity of data that gets into the database, but how do I track those instances then Tag: DirectShow Development Directshow : to create hotspot within video.

    - wlanapi.h WLAN_BSS_LIST fixed array size I've been developing a tool that implements the Native WiFi API. Upon looking through the wlanapi.h structs, I see that many of them have lists with a fixed size of 1. For example, WLAN_BSS_LIST has wlanBssEntries as: WLAN_BSS_ENTRY wlanBssEntries[1]; If I call WlanGetNetworkBssList, this struct returns with wlanBssEntries being an array of size WLAN_BSS_LIST.dwNumberOfItems. This is as expected. If I return this newly formed struct to a calling function, my calling function receives wlanBssEntries as an array of size one. The sole item in the array is correct, but all of the other items have been cut off and any index into the array beyond that results in garbage. Is there a way to return this struct and obtain the correct value, besides the obvious band-aid of giving wlanBssEntries a hard-coded size Tag: DirectShow Development Directshow : to create hotspot within video.

    - Exit PowerShell Script when a program fails I make multiple calls to a executable in a script file named Script.ps1 (shown in the box below). ./MyProgram.exe parameter1 ./MyProgram.exe parameter2 ./MyProgram.exe parameter3 ./MyProgram.exe parameter4 It continues to exucute the command in line 3 even if the program in line 2 exits with non zero error number. One way to handle this is to test $ after each command. Is there a way I can achice the same without checking it after each command something I would set right at the top saying quit when a program returns non zero status In Korn Shell (KSH) it is "set -e" at the top of the script.

    - Up & Down Key Events Using a COM SideShow Gadget, I am catching right, left, & select key events without any problem using an SCF btn and catching the related SCF_EVENT_NAVIGATION events. But when it comes to getting the up and down key events, I'm not having any luck. There is some interesting wording in the documentation... "The ButtonKey simple type defines the type that contains valid values for the key attribute of the btn element . The valid values are "enter", "back", "left" and "right" representing the set of buttons that can be overridden from the recommended set required to interact with SCF content (the recommended set also includes "menu", "up" and "down", which always have fixed functions). Software on each device maps the physical buttons to the virtual buttons." at http://msdn2.microsoft.com/en-us/library/ms744156.aspx So is there any way to get the "up" and "down" key events as a Gadget Looking Up, Steven Tag: DirectShow Development Directshow : to create hotspot within video.

    - Audio Muted during debugging Maybe this is more of a VS2005 question... VisualStudio 2005 Windows XP SP2 448 MB RAM 1.66 GHz Athlon (mobile) I'm working on a DirectShow prototype that runs fine without the debugger attached.... Debug/Release mode both. I can open the executables from Windows Explorer, and everything works as expected. The application puts three nodes into the timeline (source files in sequence), and then plays them back. However, during debugging, the ActiveMovie audio is muted . All the video is rendered, and then IMediaEvent::waitForCompletion() blocks indefinitely... and won't return. This ONLY happens while the debugger is attached. I can get it to stop happening if I set a breakpoint somewhere before "IMediaControl::Run()" (which runs the FilterGraph). If I set that breakpoint, and then F5 to resume debugging, the audio renders fine. I've quit out, rebooted, and restarted the project. Like I said; I've already checked all the return values from each of the interface-methods that build and setup the graph; I made sure the output pins are rendered--it's just that in Debug mode... if I "let it fly" without a breakpoint, I don't get audio. Another pertinent piece of information: The output window of the debugger seems to fire some C++ exceptions right about the time that "IMediaControl::Run()" is called... but they are handled (I guess inside the loaded .dlls) ....... Any clues as to what might be going on Thank you. Chad Tag: DirectShow Development Directshow : to create hotspot within video. Software Development for Windows Vista

Hi,

I want to make an interactive media player. In that I want to provide facility to create hotspot in file and tracking perticular object around which hotspot is drawn. Also I want to add some metadata in the original video file.I want to do it in mpeg4,windows media format, avi format video files.

I read on microsoft's site that directshow has ability to create interactive media file. Is it possible in directshow if it is possible please help me if anyone can.

Thanks in advance.

Regards,
Chirag.

Re: DirectShow Development Directshow : to create hotspot within video.

Thore Karlsen

You can certainly do this in DirectShow. You'll have to create a transform filter that draws the hotspot over the video. There are a couple of options for the metadata depending on your needs. It's going to be a bit of work, but it's possible. Smile

Thank you for reply.

Can u send me some more details please.

Re: DirectShow Development Directshow : to create hotspot within video.

Thore Karlsen

The best way to get started is by reading the MSDN documentation for DirectShow and learning the basics. Once you know how DirectShow works and can build simple graphs it will be easier to ask more specific questions when you get stuck.
