i couldn't find a directx forum...and as i am programming it with managed c++, i posted it here!

Oh, OK 
Most posts in this forum are not to do with MC++. Why did you use MC++ ?
What are you using to play videos ? DirectX ? Windows Media Player ?

i am planing to use the vmr9 from directshow
|

Don't. The latest version of DirectShow is full of bugs. I've written an article on CP, listing the ones I've found, other people seem to keep adding them.
I ended up rewriting my app to use Windows Media Player.

i need to do video mixing....so i dont have much possibilitys!
so, how would you sync videos over multiple machines??
|
|
|
|

Dunno. I synched them across multiple instances of WMP on the one machine by setting up a timer that checked if they were more than a given distance appart, then I reset the position of the player that wasn't playing audio. Doing it across multiple machines presents problems with that approach, if the machines are all also playing the audio.

only one machine would be playing audio! so thats no problem!
i thought of it too, to sync them manualy with a timer! but i have no idea how this will work over network! what latency does an winsock connection produce on a local network?
if it is that high that it causes problems, how to measure the latency so i can compensate??

ps: i was not planning to use manged dx...cause the video/audio part of it sucks!! i would use the interop way to access the vmr9

I doubt the latency would be noticable, but you could send info about when the reading was taken, then the only problem you have is syncing the machines clocks.

hmmmm....another possibility could be to sync the audio cards of the machines digitaly (via spdif) and to make the audiocard the reference clock for video!! that way video should be always in perfect sync!
what do you think??

Sounds good to me

Hello everybody!
I have a question. Anybody knows why managed function calls faster in MC++ rather than unmanaged function (defined with #pragma umanaged)? The differences is about 4 times slower.
Thanks for your answers!

If you are compiling a managed application, any unmanaged code, is handled by the Interop Marshaler. It makes a number of additional operations to make the coding of the application appear seamless. Actually, it creates data buffers and loads your data, copying the data to other buffers and casting to compatible .NET types. I'm simplifying a little. But, it's much slower, especially if you have alot of data to transfer.

I am having a service which is running under default system account. From within the service i am trying to get the file version of a file which is available in the network path (say the path is "\\xyz\C$\Winnt\System32\calc.exe") using GetFileVersionInfo() function.
The function fails since the service is running in the SYSTEM account and i had connected to the remote host ("\\xyz\C$") as ADMINISTRATOR.
Please help me with some other way of obtaining the file version for a remote file from the service.

Can someone please supply me with the
string fromat to get rid of a leading zero.
String str = S"0.4";
String::Format({0????}, str); (or whatever)
to result in S".4"
Thanks much!

OK -- I solved my own problem...
I got the follow two to work
Single sgl = 0.4;
Console::WriteLine(sgl.ToString(".0"));
String* str = String::Format("{0}", sgl.ToString(".0"));
Console::WriteLine(str);
But could not get any form of String::Format Method
of the form {index[,alignment][:formatString]} to work.
(See String.Format Method .NET Framework Class Library documation)
String* tens = String::Format("{0:.0}", sgl.ToString());

*sigh* I need to create a standard disclaimer to post in this forum. 99% of the questions posted here have nothing to do with managed C++, and this is no exception.
And because you posted anonymously, you probably won't get an email telling you this, and so the question will go on to be unanswered.

Can anyone explain to me a method by which a system could dynamically store an array (or even better a vector) of objects, with this allocation being triggered by a GLUT library function like glutMotionFunc(foo);
thanks

I meet some problem when I compiled this code:
double x1=
float x=float(6426.81125084);
TRACE("\n%f",x);
The result was: 6426.811035, was it incorrect???????
But when I used:
float x=float(6.81125084);
TRACE("\n%f",x);
The result was: 6.811251, was it correct??????Thanks.

Where is the float being turned into a double ?
Sorry dude, floating point math is not exact. Fixed point is, but you need to impliment that yourself.

How do I send a keyboard event to my application?
I want to control the cursor position in a
numericUpDown (or domainUpDown) control. (I
have thought to do so with a keyboard event.
Perhaps there is a better way.)
