which control are you using to display the video!

Hi,
I am using a picture control to display the video, play , pause and stop buttons on the dialog box to play/pause/stop the video. Play/Pause functionality has been implemented using DirectShow.
I am not able to start the timer from the time when user has paused the video. Timer should start incrementing from where it was stopped when user pressed the pause button.
Regards,
Mbatra

This is all laid out in that article I linked you to earlier. When the timer is fired, DoTimerStuff() is called. That function checks to see if the audio file is playing. If not, nothing happens (i.e., the progress bar is not updated).

Hi,
Thanks for the reply.
I have done the progress bar stop and continue.....but now Issue is with Timer. I am able to stop the timer when user presses the Pause button........Next when user presses the Play button, the timer is not updated.....it remains at that position only.
I have again started the timer when user presses Play button, but it does not increment, it remains at the position where it was stopped.
Any idea how to update the timer with the Pause and Play buttons.
Regards,
Mbatra

Hi,
I want to know whether opcode can give me the messages besides triangle. As mesh which is defined in the opcode is consist of triangles, but most of my model is constructed using polygons, so before my collision qurey, I have to transform the polygons to triangles, but i want to know wether i could know which polygon the triangles detected are belong to. if the anwser is yes, how can i get the message?

Hello, as i want to use the OPCODE to perform collision detection,but according to the user manual, i can only get the vertex and normals that overlapped,so i want to know wether i can get the message about which polygon the vertex belong to. because that will be a important reason for me to decide wether use the OPCODE to perform my collision detection.

OPCODE is developed for collision detection in computer graphics, do you have the experience on it. And as I have no, and I am surveying about which manners can meet my request.

I had got the resource from this address, and i also have read the mannual about the OPCODE, but as I want to learn some details about the OPCODE, I found it was difficult. And i had got the two projects "opcode" and "CDTestFramework" from that address. because i had not found the information about how to get which polygon the detected triangle is belong to in the user mannual. i hoped to find my anwser in the two projects above, but I find it was difficult to read the code in the two projects. if you had some experience about using OPCODE, i really wished you could give some suggestion about how to read the two projects. And as one of my request is two get the polygons, so if you know, can you tell me is there any manners i can get the polygons. If the answer is NO, i think I have to think about take us of other detection manners.
Thanks and Best Wishes.

you might get better results if you ask this in the Algorithms or Graphics forums. this is a C/C++ forum, and your question doesn't seem to have anything to do with C/C++.

Hi all,
I have a program that calls magnification.lib in windows 7, windows 8.
(I'm calling #include magnification.h)
But we know this library doesn't exist in windows XP.
How can I ignore this library when opening the application in windows XP?
|

Create function pointers in a header file for all the magnification APIs that you're going to use.
Check the OS version and if Vista or above, call LoadLibrary on Magnification.dll .
After this call GetProcAddress on the function to initialize the function pointer.
So the header file could look like this -
typedef BOOL (*PFN_MAG_INITIALIZE)(void);
From the main program, you could have a call to some function called InitMagnification .
In the InitMagnification function, do the dynamic loading after checking the OS version.
PFN_MAG_INITIALIZE MagInitialize = NULL;
if (osVersion >= "VISTA")
{
HMODULE hmod = LoadLibrary(_T("Magnification.dll"));
MagInitialize = GetProcAddress(hmod, "MagInitialize");
}
In the source where this function is called, do the checking as follows -
if (MagInitialize)
{
MagInitalize();
}
I have omitted error checking, which you have to do.

Thank you very much. After posting this question, I did exactly what you told me to do. Thank you again

Thank you. I performed an explicitly link to my DLL.

As an alternative, you could use delay load dll. In this case you do not need to change the code you have already written (related to statically linking to the library), all you need to do is just do not call chunk of codes related to magnification at all. Saves you a lot of annoying LoadLibrary/GetProcAddress calls.
However, it looks like you have already implemented it. So, just learn about this, so that you could use in future

Thank you for introducing me this.
I found this way is more interesting than using LoadLibrary, but I still prefer to the old method, because it helps me to compile the program even on Windows XP

Hi,
I am using DirectShow to play, pause audio / video files. Now I want to implement mute functionality for any audio / video file. Is this possible using DirectShow or I have to use any other method.?
I want to make sound off from a currently playing video file, When user clicks on the sound button, audio should not be heard.
Any help will be appreciated.
Regards,
Mbatra

So do you want to pause the playing of the audio file, or just mute the speakers (while the audio file continues to play)?

Hi,
I just want to mute the speakers while audio file continues to play.
Similar to mute functionality, don't want to pause the audio file. it should continue playing while we mute the sound from the speakers.

Hi,
I have created a property sheet and it contains 3 pages. I want to disable any of the page based on some condition.
Is there any method of disabling pages in a property sheet.?
Any help will be appreciated.

Can't you use the EnableWindow(BOOL) method? Supplying TRUE to enable and FALSE to disable. See here[^]
