    - Sound Problem Same situation here, but even more dire. I have Creative Audigy 2 ZS Notebook. After upgrading to Vista Business, I had sound. However, when I started up my laptop the second time, my laptop recognizes the sound card as a "phantom component". IT DOESN'T SHOW THE CARD AS INSTALLED!!! Weird thing is, D#ll had it intergrated in the laptop. If the new upcoming driver doesn't work, I might roll back to XP Pro. If push comes to shove, ya might have to do that too. Peace!

    - How to transform a Byte[] object containing ink (ISF) to a Byte[] readable by Crystal Report with .NET 2.0? So it seems like your goal to have an image of your ink that will show up on the reports. Is that correct You can render the ink to a bitmap in memory and save that to byte array representing the desired image format (jpg, png, etc.). You could store this alongside with the byte array for ISF (which you will still need for roundtrip purposes). Here is a code snippet that shows how to render ink to a bitmap and persist that as a byte array in jpg format. Code Snippet Bitmap inkBitmap; Rectangle inkrect = _inkOverlay.Ink.GetBoundingBox(); Point bottomRight = new Point(inkrect.Right, inkrect.Bottom); using (Graphics g = this.CreateGraphics()) { _inkOverlay.Renderer.InkSpaceToPixel(g, ref bottomRight); inkBitmap = new Bitmap(bottomRight.X, bottomRight.Y, g); } using (Graphics g = Graphics.FromImage(inkBitmap)) { g.Clear(this.BackColor); _inkOverlay.Renderer.Draw(g, _inkOverlay.Ink.Strokes); } MemoryStream bitmapStream = new MemoryStream(); ; inkBitmap.Save(bitmapStream, ImageFormat.Jpeg); byte[] imageByteArrayToSave = bitmapStream.ToArray(); Side note: If you are running on Vista, you can also use the new overload of the Renderer.Draw() method that takes a bitmap reference directly. This will result in a higher quality bitmap. In that case the second 'using()' block would be replaced with a single line '_inkOverlay.Renderer.Draw(inkBitmap, _inkOverlay.Ink.Strokes);'.

    - FreeCoTaskMem (Memory Access Exception) in Vista, fine in XP .NET 2 Thanks guys, Both very useful, I will bare in mind with regard to Vista Compatibility. "The FreeCoTaskMem(pDib) call inside the try block is unecessary since you're calling it again in the finally block" Sorry that was simply a remnant of moving the dealocation around, the point was that the call to FreeCoTaskMem in the try block throws an exception, I simply moved it forward from the finally block to test that and left it in my pasted code. " Good thing Vista errors since it exposes bugs in your code" you are totally correct, the intptr.size is sloppy, guess I must have been thinking 32, 64 (perhaps I was drinking and coding that night!) the worst thing is that has been running seemingly well, and most certainly un detected on XP systems for a long, long while now, and I guess that within that light the tighter sensitivity and control on Vista can only be a good thing. Thankyou all. Tag: DirectShow Development WM ASF Writer memory leak? Software Development for Windows Vista

    - Is ISampleGrabberCB::BufferCB is called only on Motion Detection? Hi, I am writing a small "Capture from WebCam" application and I have notices that if my webcam is facing some surface (w/o movement) the BufferCB is not called in my callback. Also, when I rapidly move it around, the BufferCB is called. Is this correct that BufferCB is called only if the frames are changing (like in Motion Detection) Please give me more details. Also, Is there a way to capture something from a script, if yes - please tell me the interfaces available to scripting lanuages. BTW, I have tried WIA, but it doesn't work on my machine (even the scanner and camera wizard) cannot capture anything. Thank You, Vlad. Tag: DirectShow Development WM ASF Writer memory leak?

    - Application won't elevate with manifest It works now I applied a clean Windows Vista install and recompiled the install to include the manifest. I am now prompted for an administrator password. Looks like it was a cache issue. Unfortunately I haven't found a way to embed the manifest. The application is written and compiled in VisualBasic 6.0 and I can't find a way to embed it a manifest.

    - InkCanvas selection adorner Hi Boris, it is actually easier than that. You can re-use the existing lasso functionality of the InkCanvasEditingMode.Select mode. Then, in the SelectionChanged event, you can get a reference to the selected strokes (and/or elements). Now clear the selection (to get rid of the standard adorner) and then bring up your custom adorner. I have put together a sample app that demonstrates this with a simple, custom adorner that allows rotation of selected ink. I will put it up on http://wpf.netfx3.com/ once I have the permission to post there. I'll post again with the actual link to the sample.

    - How to record from 'Wave' or 'Stereo Mix' in Vista? Thanks for your answer, Larry. [What APIs did you use for this in XP They should continue to work on Vista.] As I said in earlier post, I used "DirectSoundCapture" to capture that audio stream on the "source-line" selected in Windows record control utility. As you know, DirectSoundCapture buffer can capture the audio stream through the selected mixer line. For example, If "Mic-in" is selected, DirectSoundCapture buffer will capture the audio comes through Mic.-in line. And if "Line-in" is selected, it will capture the audio stream through Lini-in line. Yes, I know this should continue to work on Vista. However, as the title of this thread saying, I could not find the way to record the audio stream on 'Wave' or 'Stereo Mix' line on Vista Actually, "Line-in" and "Mic-in" are real external "ENDPOINT devices" but 'Wave' or 'Stereo Mix' line are NOT. Actually, on XP or earlier versino of Windows, I could select 'Wave' or 'Stereo Mix' line through ::mixerXXXX() APIs. For example, I used ::mixerGetLineInfo(...) API to get MIXERLINE structure. And if the "dwComponentType" member of MIXERLINE structure is MIXERLINE_COMPONENTTYPE_DST_WAVEIN, then I used ::mixerGetLineControls(...) API to get MIXERCONTROL structure. And if the "dwControlType" member of MIXERCONTROL structure is MIXERCONTROL_CONTROLTYPE_MUX, I could select the wanted record source line (i.e., 'Wave' or 'Stereo Mix') by using ::mixerGetControlDetails(...) or ::mixerSetControlDetails(...) APIs. However, the above way using ::mixerXXX APIs makes empty record source line list on Vista. So, as I said, I wrote new code using "Device Topology API" and I could get IAudioInputSelector interface from Mux subunit part. However, this interface also did not give me a solution. IAudioInputSelector interface did not show 'Wave' or 'Stereo Mix' line but it shows only the endpoint devices. Ok, to make a long story to short, the problem is... although DirectSoundCapture buffer can capture the audio stream through the selected record source line, there's no way to select 'Wave' or 'Stereo Mix' record source line which are not real external "endpoint devices" on Vista. [WASAPI has a special Loopback mode that allows a client to capture the post-mix audio stream, that may help as well.] Ok, I'll try writing new code using WASAPI as you said. However, before doing that, could you please confirm that I could capture the audio stream (PCM data) with this API, although there's no 'Wave' or 'Stereo Mix' line in the parts of Device Topologies ( When I first re-wrote the code using 'Device Topology API' for selecting 'Wave' or 'Stereo Mix' record source line on Vista for myself, I though there's no need to change DirectSoundCapture code but I need change only the record line selection code for Vista. However, I failed as I explained. So, if I should use WASAPI instead using 'DirectSoundCapture'+'Device Topologies API', I'd like to get confirmation from you that WASAPI will really sort out my problem or not.)

    - openthreadtoken fails on Windows Vista but not on Windows XP OpenThreadToken will fail if you are not impersonating. If you never call any impersonation APIs, then the process will have a token but individual threads will not. Access checks typically verify access against the current thread token, or the process token if there is no thread token. You should do the same: if OpenThreadToken fails with ERROR_NO_TOKEN, you should call OpenProcessToken(GetCurrentProcess(), ...) instead and use that token.

    - How does the STS encrypt the token? In most of MS samples with federation, the STS signs the SAML token and encrypts the signature part with the RP public key. I think the same set of questions applies to signature. Actually in samples, the IP has the RP key to encrypt the signature. So - how the IP can know which RP key use if the IP issues tokens for multiple RP's - how the IP can retrieve the RP key to encrypt signature and token - etc.... Is the AppliesTo statement can be used to solve the first question Tag: DirectShow Development WM ASF Writer memory leak? Software Development for Windows Vista

    - Please Help! Communication from App to Workflow and visa versa Hi All I have been playing with Workflow for a while now and im still struggle with a major part of it all, communication between the host and the workflow. Most the examples I find wont load properly (they seem to be aimed at the beta version). I have built some simple workflows that do stuff like this. 1, Work flow is started up and parameters passed across. 2, Workflow runs, does some tasks (sends emails, writes to database). Application sits there minding its own business. 3, Workflow waits for user action before starting second phase. 4, User kicks off second phase of the workflow. Button on form calls the even that the workflow needs to carry on. 5, Workflow runs and does more tasks. 6, Workflow finishes and i capture this in the application. What I want to do Is when the workflow finishes the first phase and waits for the next event for there to be some communication that is has finished stage one and requires the user take some action. I have tried using CallExternalMethod but whats the code I need to put into the application to handle that event fireing I hope this makes sense and any help would be great!! Im at my wits end with it all :( Thanks Tag: DirectShow Development WM ASF Writer memory leak? Software Development for Windows Vista

    - VMR9Allocator in fullscreen Hello, It seems that the same kind of question has already been asked, but there is no answer yet. I am using the Directshow sample VMR9Allocator, and I need to display my application in fullscreen. First I simply tried to maximize the main window size in popup mode; it works but I still have the common tearing of the windowed mode. So I would like to implement the vmr9 renderless fullscreen mode, but I don't know how to proceed, I can't find any information about that. VMR9Allocator is already in renderless mode. Now when creating my device, I changed my D3DPRESENT_PARAMETERS and put Windowed at false ; however in this case it seems that vmr9 reads my video but nothing is diplayed on the screen. I don't know what I am missing. Could somebody help me Thank you for your time and consideration. Tag: DirectShow Development WM ASF Writer memory leak? Software Development for Windows Vista

    - Question about IFileSystemImage Hi, Henry, About the 3rd question, I think I found the solution!! I found that I always used the same IDiscFormat2Data interface pointer... After re-create the IDiscFormat2Data instance, I could burn multi-pass successfully !! Thanks God! So one IDiscFormat2Data instance could be used only "once" for image recording About the 2nd question, I'm trying to figure it out. If you could, please kindly provide the possible functions that might increase the reference count of IFileSystemImage. Great thanks! Tag: DirectShow Development WM ASF Writer memory leak?

    - Merge Modules & Vista Certification (Test Case 23) I was struggling with this issue too. Then I created a "rollback custom action" as opposed to a deferred custom action and sequenced it in the Install>Execute sequence with a value of 2400. This rollback custom action executes only in the event of a rollback and deletes the Microsoft CRT, MFC files that I install in the WinSXS directory via merge modules. My rollback custom action calls a function that deletes a total of six folders containing all the MFC, CRT files that I install. I trigger a rollback by putting a bad file in my install package. If I don't put the bad file and create a good install package to not have a rollback during the install, my application gets installed properly and my MFC, CRT remain in the WinSXS directory.

    - Unable to find a control using UIAutomation We have a new WPF web application which genearates a lot of dynamic controls. One of them is a "TextBlock". I used the UISpy to see the control properties. I was able to see the control only in the Raw tree and not in Contol tree view. I tried using the below code to get the control AutomationElement parent; //Initialized parent element. AutomationElementCollection coll = parent.FindAll(TreeScope.Descendants, Automation.RawViewCondition); coll had 0 elements in it. Then I used the TreeWalker to see if I can get the control, using the below code and I was able to get it. TreeWalker walker = new TreeWalker(Automation.RawViewCondition); AutomationElement e = walker.GetFirstChild(parent); while(e != null) { e = walker.GetNextSibiling(e); } The only property that looks a bit suspisious to me about this control is its AutomationElement property ��IsControlElement�� is false. So my question is, why can't I get the control using FindAll/FindFirst method when I am mentioning it to use the raw view. Is there something wrong I am doing that is making the IsControlElement property of my TextBlock false Smitha Saligrama MSFT Tag: DirectShow Development WM ASF Writer memory leak?

    - How to activitybind with a registerattached property in xoml? How do you express an activitybind in xoml when the path needs to point to a registerattached property I've defined my own CompositeActivity class with one dependencyproperty added using the RegisterAttached method. A little like the PrioritizedInterleaveActivity in Essential WWF. This activity is used in a xoml. It has a single child activity, a Sequence. The sequence has a number of activities. One of the activities needs the actual value of the dependency property attached to the sequence. But how do you express that in xoml "{ActivityBind MySequence,Path=PrioritizedInterleaveActivity.Priority}" does not seems to work. It results in the following error: error 1549: Activity 'PrintLine' validation failed: Path 'PrioritizedInterleave.Priority' used to specify member for 'MySequence' is invalid.

Hi all,

I have tried to build a graph to capture images then save them into a WMV file. I used a SmartTee filter to preview the result and save it to file.

I found that the virtual memory increase stably when I did the following steps;

1. Build graph, and connect the source fillter, SmartTee filter, Render filter, ASF writer.

2. Run the graph.

3. Stop the graph.

4. Remove all filters, then release the graph

5. go to step 1.

If I implemented the steps without adding ASF writer, the virtual memory looked normal.

My system has installed HotFix_839203 that fixs Windows Media Component memory leak. But it still happened.

Does anyone meet such problem
