Each has their own strengths and weaknesses.

That mean it is depend on the application going to develop, isn't it?

I tried this once here.

Thanks. But I think it is better to go with SQL. Do you use such any...

Hello everyone...
Good day to you....
Is there any way to dynamically mask a group of bits to retrieve certain values from them?
0000 0000 0000 0000 0000 0000 0000 0001 0000 0000 0111 0010 0001
MSB LSB
There are a total of 52 bits .
Now there is a variable say "x" depending on which I should divide this bits to calculate two values.
I am using shift operators and masking to get this job done.
Suppose x is 20
0000 0000 0111 0010 0001 would give me the first value and
0000 0000 0000 0000 0000 0000 0000 0001 would give me the second value.
I am able to do it only for a predefined value for x i.e only for 20.
I have to mask these 52 bits in such a way that I am able to get the answer for the varying vlaues of x.
Is there a way to do this anyway.
Please help me if anyone knows to do this.
Thanks

u mean, you want to return first x bits in value 1 and remaining 52-x bits in value 2 right?

Yes you are correct..
If you could let me know how to do it.
thank you

give me few minutes iam working on it.
and is your variable a 64 bit integer?

and here is what you require.
UINT64 value,value1,value2,maskval;
maskval=0xfffffffffffffff;//assigning the 8 byte integer to all 1s.
maskval=maskval<<x;<i>//x is the number of bits you want to mask.
maskval=~maskval;//toggling the bits from 0 to 1 and vice versa.
value1=value&maskval;
value2=value>>x;

Thank you very much for your help.
I ll be obliged if you could illustrate me with the example which I have mentioned on my question.
0000 0000 0000 0000 0000 0000 0000 0001 0000 0000 0111 0010 0001

Try coding it and giving a few values to X while debugging or printing them in the screen to know if adapt to your needs

why not, definitely.
value=0000 0000 0000 0000 0000 0000 0000 0001 0000 0000 0111 0010 0001
first, you will define a maskval with all 1s.
1111 1111 1111 1111 ........upto 64 bits.
then, shift the bits left, x many number of times.
for example, if x is 6, the lsb portion of ur maskval looks like this
1111 1111 1100 0000
if you not this value,
1 s become 0s and 0 s become 1s. something like this
0000 .......0000 0000 0011 1111.
now if you and this maskval with ur original val, then
first 6 bits will get filtered into value1.
to get value 2 right shift ur actual value by x bits.
thats it.

hi,
I have a server and client application, which are running on different machines and communicating each other thru sockets. Its using TCP sockets, for which i am using Win32 APIs(WSAStartup, socket, bind, send etc.). I am sending text data from client to server periodically, at a rate of 50 ms. When i run both client and server in one machine, the sending and receival are proper. But when i run them on different machines, sending and receival are not synchronized. When i display the buffer after a receival operation at the server end, it shows same data appended to itself several times. I guess this problem is bcoz the rate of sending and receival are not the same, or the network delay.
All ur suggestions are most welcome..
Thanks in advance,
SYAMLAL

How are you reading the incoming data exactly ? You need to supply the number of bytes you want to read when you call the recv function. So, in order to read only one message, read only the size of the message. If it is variable, then the best way to do it would be to send the size of the message before the message. You read the size (1, 2 or 4 bytes, depending of the maximum size of your packet) and then you read exactly that number of bytes to get your packet.

Are you using a synchronous or an asynchronous socket?
