Did you notice the EventReceiver() method in the sample project I sent you? It's handling the EC_COMPLETE message.

Hi David,
Thanks for the info....I didn't notice that.
Now I have one doubt..I am able to figure out when the video play has finished. But at the completion of the video file, I am going to stop the time and reset the progress bar position to 0. Neither the timer is stopped nor the progress bar. Timer keeps on running and progress bar also keeps on stepping up.
Can u please help me how to stop the timer and progress bar.
Regards,
Mbatra

If you are using pretty much the same code as in the sample, it looks like you can simply add KillTimer(hOwner, MY_TIMEREVENT); to the DoStop() function.

Hi,
I am using DirectShow to Capture / Play / Stop a video. After capturing a video, when user clicks on the play video button, Video plays fine... But I want to display the progress bar along with the video which will show the user how much video portion is left to play. I also want to display the time along with progress bar, which will take the total duration of the video and will show the user how much time is left.
Anybody have any idea or suggestion for the above mentioned.
It will be very helpful if you can provide me the sample code for the same scenario.
Regards,
Mbatra

Using your own IP address with that client is unlikely to work since you probably do not have a daytime listener on port 13. As to your server code, you need to explain where it fails and what errors you see.

Hi. I'm getting bind error for the server's code.

Try using something other than one of the well known ports: 5001 for example.

Seems like I cann't create a socket either with bind or Create with a parameter other than NULL
when do I get WSAEADDRNOTAVAIL
If I create a socket with Either Bind or Create with a NULL parameter for Create or Bind
ANd then I use GetSockame I get NULL for the IP address
IS this a strange occurence

a little background first I am writting a front end to the Hercules MainFrame Emulator this MFC C++ app
I also have a MVS started task communicating with this MFC C++ app when I first bought the Lap top
and moved in my code it worked the its a quad core lap top that I bought in August
Since then my machine has slowed and I am getting the timeouts
I Tried using Socket and Bind to Create the socket as opposed to just using the create
but in case it does take the IP address I use 192.168.1.4 which I think is the IP address of the laptop
I tried 192.168.1.111 as that is the ip address of my laptop 192.168.1.4 is routed to 192.168.1.111
I have a a loop in My CWinApp:: initinstance creating 4 socket threads

HI
Hope this is better
As I said I bought my quad core laptop in August and my code was running faster
as of now my connections time out
One of my questions is how come when I do a GetSockName after a Successful Bind
code is in The Dervied CWinThread SockCleintThread::Initinstance
The ip address in he SOCKADDR structure is 0 ?

How do you invoke the C++ compiler (command line, please)?
You have to g++ (instead of gcc), see, for instance here[^].
Veni, vidi, vici.

I am using CC - command for compiling, What is the command for g++
|

You are using the C compiler.
g++ is the command for invoking the C++ compiler, e.g.
g++ myapp.cpp -o myapp
If you are using a makefile, set CC=g++.

No you won't. Just show us the first few lines of your source (where your #include statements are), and the lines that are producing the errors.

#include <cstdlib>
#include <iostream>

Plenty of errors are coming, i couldn't figure it out.
But my question is same program is running in other compilers but why it is not running in g++.
Might be there is a small bug.

Manoj7390 wrote: Plenty of errors are coming, i couldn't figure it out.
Like I said, show us the line of code and the error message; the first two or three should be enough.
Manoj7390 wrote: Might be there is a small bug.
Most unlikely, it is much more likely that the compiler cannot find one of the include files, or there is some other setting specific to g++ that you need to add. I do not have a Linux system so cannot test this.

Hi. I have written the program for turbo encoder, for every single bit, it gives three bits as output and I am storing it as a integer. Now the problem is how to concatenate these bits in the integer form.
for example...
int u = 1; int p = 0; int q = 1;
Answer = 101;
|
|
|
|
|
int Answer = (u << 2) | (p << 1) | q

I cannot use shifting here, because i am considering bits in the integer form. if i shift, data will change know.
Suggest any other way to store bits in C/C++
|
|
|
|
|
As stated, your sentence makes no sense. Please elaborate.
Veni, vidi, vici.
|
|
|
|

I am implementing turbo encoder, I will give some data as a input and i am converting it into the binary, since i don't know how to store and which data type for binary values, i have stored those binary values as integers only. Now i need to concatenate three bits at a time, I need only 1's and 0's not the integer values. If i shift these values i will get more than 1.

|

Manoj7390 wrote: If i shift these values i will get more than 1
Of course.
Now look at decimal case:
if you 'concatenate' the digits 1,5,7 then you get the number 157 that is no more in the 0-9 range.
An alternative would be using strings, that is, you concatenate the character representations of the digits into a string ('1'', '5', '7' => "157").
You may apply exactly the same argument to binary (that is base 2) digits: if you concatenate 1,0,0 you get the number 101, that is decimal 5, no more in the 0-1 range. The string concatenation method would give you "101".
You may find interesting the std::bitset[^] class.
However it does not prevent you from gaining a proper understanding of numerical bases (see, for instance, Numeral System at Wikipedia[^]) and how numbers are stored in computers.

This has nothing to do with C/C++, it's how computers work. If you will not use the shift operators to store the three bits together then you cannot store them.
Use the best guess

int Answer = u * 4 + p * 2 + q

Which the compiler will almost certainly optimise into shift operations.

possibly. but that extends the definition of "you" quite a bit.
int Answer = u + u + u + u + p + p + q;

you originally wrote "If you will not use the shift operators to store the three bits together then you cannot store them."
that's the "you".
i think it's reasonable to differentiate between what the programmer writes and what the compiler does.

Sorry, but I don't understand what point you are trying to make.

though richard solutions is best.. i am suggesting simpler approach for this in my college days
int result = i*100 + j *10 + k;
Jokes apart! are you looking for it's integer equivalent. i.e. say you have bits like this i=1,j=0,k=0 for which decimal equivalent is 4 ( binary of 100 = 4 i.e. 22 + 0 + 0 )

No i dont need the decimal value of binary. I need to that as it is as 1's and 0's.
if i have u=1; p=0; q=1;
Then i need result = {u,p,q} = "101" (its neither decimal '5' nor decimal 'one hundred one')
Just i need to concatenate bits.
or else help me how to store binary values and which is the data type for that.

if you looking for string value as i understand by double quote used by you, you can use sprintf or sprintf_s.
now if you want to store the binary value resulting from you operation (as you mentioned they are only 3 bit coming), you can use char datatype (1 byte) and store the decimal equivalent of it there, internally it store its binary equivalent only,
for say you got 101 which decimal equivalent is 5 and when you store same in char variable, it binary representation would be
00000100

But i need to concatenate the bits which are in different variables. how to concatenate those.. Since i cannot use shift operator here because of binary.

What on earth are you talking about? I have shown you exactly how to concatenate these fields into a three bit value. If you really cannot understand that simple operation then I don't think you are going to get very far with this project.
