Simple, but did it - didn't thought of it, because Visual Studio won't let you add one in a Winforms-project. Thanks.

Hi, I'm trying to write a Winforms Application, in which one Windows has the sole purpose to host a WPF Control. The window itself is transparent (using the TransparencyKey-Property) and so are parts of the hosted WPF control(Using Background-Color=Transparent). The ElementHost has its BackColorTransparent property set to true. Problem is: The transparent areas of the WPF control are painted in the background color of the winforms-host. The one that should be replaced by transparency (because of the TransparencyKey). Seems like an airspace-problem to me, but I'm not sure about that. How can i achieve true transparency (so i can see the underlying desktop through my WPF Control)? Any help would be appreciated. Michael.

If you can assume that the Adobe Reader is installed on the target machine, you could use a webbrowser-control to display the pdf, if I'm not mistaken. Michael.

Hi, have a look at this: http://www.theserverside.net/tt/articles/showarticle.tss?id=ShellExtensions[^] Aside from that, i heard it's not wise to do shell extensions in managed code - if there is more than one of these installed and the target framework versions are not the same, only one is executed and you can't easily determine which it will be.

Hello, the only program i know that streams "directly" to a desired audio format is the VLC Media Player. The good news is, that it is open source and quite well documented. But... it's unmanaged (of course) and i think you will have to dig through quite a bit of code in order to find something useful. Anyway, try this: http://www.videolan.org/developers/vlc.html[^] Michael.

Hi, i've got a problem regarding the System.windows.forms.webbrowser-control as it won't host certain plugins that run fine in the standard iexplorer. The problem occurs roughly on 50% of the machines, interestingly mainly those with windows vista on it. (Although there are vista-PCs where it runs just fine). Any help would be appreciated, Michael.

Ok, here's a new problem: Filler()(from the link above) is called, while the synthesizer is still filling the stream with data. As you can imagine, this results in a disaster. So I cannot make the stream thread-safe (because can't control the filling end) and even if i could, I would have gasps in my output because the buffer would be filled like this: (1 =data in cycle 1 2=data in cycle 2 0= no data) 11111111111111111100000000000000000 |stream is filled until here 22222222222222222220000000000000000 while it should look like this: 1111111111111111112222222222222222222 Any ideas? Edit: Ok, finally got it - i had to wrap the whole synthesizer-class to make the stream thread-safe, but finally, it works. Thanks @ all.

Thanks a lot, that should do it. I'll try it later.

Hi, I'm writing an application that uses an System.Speech.Synthesis.SpeechSynthesizer to generate some speech. The class has a method to set the output to the default audio device or to another audiostream (System.IO.Stream). But how can I tell it to use just another audio device? I think I might have to get a Stream object of that other device to pass it to the SetOutputToAudioStream() method of the synthesizer, but I have no clue how to do so. Any help would be appreciated. Michael.

Hi, I'm just confused. I am trying to implement video playback in a 2D-World using D3D. The best would be to have the video on a D3D-surface, so i chose VMR9 in renderless mode to do the dirty work :/. But i have come to a point where i'm just running against a wall: Although i'm doing quite the same as in the VMR9-Renderless sample, the program crashs while calling RenderFile(). Has anyone a working solution, which he could share?
