Hi,
I am working on a project in which I use DirectShow to Play / Pause / Stop the video. I am using progress bar which increments along with the video. Now I want to use Slider bar instead of the progress bar which should increment along with the video. Also user should be able to control the video using slider (move forward / backward). I had used timers in which I am incrementing the progress bar.
How to use Sliders so that while video is playing, slider should increment along with the video showing the progress of the video.
Anybody have any idea or any sample code for the same.?
Regards,
Mbatra

Have you looked at the CSliderCtrl members? I'm seeing SetRange() and SetPos(), both of which look like they'd be part of the solution.

Hi David,
Thanks for the reply.
These functions we can use to update the position of the slider. I
want to make the slider synchronize with the timer and the duration of the video. At any time when user drags the slider forward or backward, the playing video should also move forward or backward and timer value should also be changed.
You can say, I want the functionality similar to YouTube, playing a video and user can move forward or backward. Accordingly the video and the timer changes their values.
Do you have any sample code for the same.?
Regards,
Mbatra

That article I referenced you to earlier shows how to use the IMediaSeeking::SetPositions() method. You'll call this method when handling the TRBN_THUMBPOSCHANGING message.

you can follow this logic
- get total video length in seconds
- create slider based on resulting time
- handle sliderctrl message http://msdn.microsoft.com/en-us/library/ekx9yz55(v=vs.80).aspx[^]
- move your video time line appropriately

Hi,
I have followed the similar points. At point No.3, I want to forward the video in proportion to the slider value. But issue is how to get IMediaSeeking interface reference to the running video. So that I can set the position of the next seek frame.

In that DirectShow example I referenced you to (several times now), look at the PlayerClass::Initialise() method. It shows how to get references to three different interfaces, IMediaSeeking included.

Hi.. I have implemented ECC algorithm in C++ and it is working fine with g++ compiler... I need to apply this program to network simulator - 3. Complier of NS-3 is "./waf", there it is not building and it is giving countless errors mainly regarding "ostream".
there is a line regarding ostream in my header function....---
// ostream handler
template<int T>
friend ostream& operator<<(ostream& os, const FiniteFieldElement<T>& g)
{
return os << g.i_;
}

In the main program i am calling another header function called "FiniteFieldElement.h" function. In that function i have used --
// ostream handler
template<int T>
friend ostream& operator<<(ostream& os, const FiniteFieldElement<T>& g)
{
return os << g.i_;
}
I am calling this function and using "ostream" in so many places in main function. I am getting the errors like..
/usr/include/c++/4.6/ostream:493:5: note: template<class _chart,="" class="" _traits=""> std::basic_ostream<_CharT, _Traits>& std::operator<<(std::basic_ostream<_CharT, _Traits>&, const _CharT*)

I think it is not the problem with the code, because i am getting the output with g++ compiler. Now i am using ./waf compiler for NS-3, where i am facing problem. I am not sure ostream is supported by NS-3 because there they use NS_LOG_UNCOND("message") instead of "cout".
I am getting errors where i have used ostream. What do you mean by "ostream" and is it compiler dependent.

I don't mean anything by it, it is part of the standard C++ library. Also, I have no idea what ./waf compiler for NS-3 is, or what features it supports.

Hi,
I have a application developed in VC++(MFC).Its a MDI application.I am very new to Unit testing. So i need to use a Unit testing framework\tool for it's unit testing.
Kindly any one please suggest any Unti testing tool and also if you have any demo of that suggested Tool's implementation for MFC code, Then it will be easier to catch easier . If that testing tool is a Free like GoogleTest(gtest) then it'll be more prefarable.
I searched a lot, but i didn't get idea as per my requirement(exspecially for MFC code unittesting).So need help.Please suggest.
Thanks

Thanks _Superman 
Hoping this CPPUNIT will support all typeof VC++ App[MFC ,Win32]including COM,DCOM .
In future if i get any more docmunets related to MFC untitestng i'll update here. Again hoping the same from you too.

Hi
I am getting the above mentioned error in all my .cpp files I don't see any where I am using DAO classes
maybe they are some how included in stdafx,h yes I am compiling as 64 bit code
Thanks

Search your project files for afxdao.h and remove the include statements.

Well we certainly can't without a lot more information. You need to look at where this message is produced and try to find out how it is including such references.

Well it's pretty clear that afxdao.h is being pulled into your compilations for some reason, so you need to examine your project to find out why. As a first step, try a Clean & Rebuild to see if that clears it.
