How many more times do you need to have this explained to you before you realise that you are totally out of your depth on this? You have had lots of suggestions as to what you need to do but you obviously don't have the basic knowledge to implement them. I would suggest that you get hold of some books on basic C++ and Windows Programming and work through the sample code to get the understanding and skills you need to solve this problem.
Reposting the same question every day is just getting you more confused.

hey everybody
I want to implement file transmisstion between two client peer in
different LAN.
they get each Extranet IP and Port through http server(when they visit a
site like www.codeproject.com i will return other Extranet IP and Port)
when CLientA get ClienB Extranet Ip And Port ClientA will connect To ClinetB
in the same time ClientB Will Bind To Local Port and begin listen
my problem that can the connect oK ?，I have tested is fail but i want to know
why failed can someone tell me why
thanks

Hi,
Sounds like an excellent project. When will you have it completed?

Hi jeansea,
Your question is very difficult for us to understand. Please improve the question and we can help you. You need to be very specific about the problem you are trying to solve.

I have created a Windows service in VC6 and wanted to know how can I implement a WndProc to handle Windows Messages inside the same.

You want to get the message of which window(s)?
i cannot understand.

Standard Windows Messages like WM_COMMAND,WM_TIMER and so on
|
|
|
|

From your words, i felt that you need to get some specific messages generated by any window globally.
if so then, it sound a different intention with it
well you have to hook WINDOWS messages globally using SetWindowHookEx with WH_CALLWNDPROC as hook id [^]

A service runs in the background, so where are these WM_COMMAND's coming from? You won;t have a menu, or a dialog box...
I think you need to go back to your basics - a service communicates with other programs using various interprocess communcations.

I know that but ... The purpose I wanted to know that is I wanted to either abort shutdown or delay the time so that I can run some cleanup scripts just before the system gets shutdown.

Hi,
I want to know that can i store output from readdir() function in an array. I have a c program
#include <dirent.h>
#include <stdio.h>
int main(void)
{
DIR *d;
struct dirent *dir;
d=opendir("C:\\");
printf("Directories in C:\\ \n");
while((dir=readdir(d))!=NULL)
{
printf("%s\n",dir->d_name);
}
closedir(d);
return(0);
}
Instead of printing directories in output i want to store that result in an array.can it is possible?
|
|
|
|
|
Sure. Just you strcpy_s instead of printf to store it in an array.

Hey Superman_,
thanks for this.Now if i write
#include <dirent.h>
#include <stdio.h>
int main(void)
{
char array[1024];
DIR *d;
struct dirent *dir;
d=opendir("C:\\");
printf("Directories in C:\\ \n");
while((dir=readdir(d))!=NULL)
{
strcpy_s(array,dir->d_name);
}
closedir(d);
return(0);
}
will it works?actually at this time i can n't check the code.can you please help me?

No, you are writing all your strings into one string, so you will keep only the last one. The problem you have is that you don't know upfront how many directories you will get, so you don't know how large you have to make your array. You could choose the brute force and use an array which is large enough (e.g. char array[1024][1024]: max 1024 directories of max 1024 characters). And then in your while loop you keep an index of where to store the current directory name (simply increment it each time).
Is it a C or C++ project ? Because if it is C++, I strongly suggest you to use stl containers (std::list for instance) and std::string, this will avoid to create an array with a fixed size upfront.

hey Cédric Moonen,
yes.it is C++ project.can you please give me the whole correct code ?

ravi 12 wrote: can you please give me the whole correct code ?
No because that wouldn't serve any purpose. Instead, I'll point you to some good articles about STL, you can check this section[^] on codeproject.
Of course, that will require some time to learn but it is definitively something that you will use a lot in the future, so the time investement will pay back later.
I suggest you document yourself about std::string and std::list, that's what you will need for this project. Don't forget that google is your friend and you can search for tutorials on the net.

He seems to have lots of time considering he spent 11 days figuring out that he's unable to use FindFirstFile()/FindNextFile(). See his previous posts.

unsigned long i;
short s;
signed char c;
i = (s<<15) + (c <<9);
How will type conversion take place in this case?
Is it that:
1. s will remain short(2 bytes) thus shifting the LSB into the MSB and remaining bits turn 0; c is promoted to short then left-shift 9 performed. The final R-value is promoted to unsigned long and saved into i.
or
2. s and c both get converted to unsigned long before performing the shift operation (thus we do not lose any of the left-shifted bits)
or something else happens.
I tried it in VS6.0 and the result seem to indicate that in both s and c I did not lose any bit upon left-shifting as if s and c acted as if they were a 4-byte data type (long or int)

All shifts take place in a register.
The registers are 32-bit in a 32-bit OS.
So even though the shift overflows the variable, it will still remain in the register.
That's the reason you don't loose any bits.
