Can you use Windows APIs?
If so, check out FindFirstFile, FindNextFile, FindClose for directory traversal.
The C runtime has equivelant functions but they aren't ANSI compatible.

I'll keep this brief. My app has a member variable of type CStringList called m_channelList. I wish to add new CStrings via a dialogue box. This is how I've been trying to do it:
CWinApp* AFXAPI AfxGetApp();
AFXAPI->m_channelList.AddTail ( szNewChannelName );
But my compiler doesn't like it. I get the following error:
error C2143: syntax error : missing ';' before '__stdcall'
Is there a better way? Or at least an explaination why this error is occuring?
|

AFXAPI is defined by MFC as follows
#ifndef AFXAPI
#define AFXAPI __stdcall
#endif
hence it is an unlucky name for your variable. Use instead
CWinApp* myApp AfxGetApp();
myApp->m_channelList.AddTail ( szNewChannelName );

Well, it never fails that I would do something like that. Thanks.
I have another problem now though. When I use
CWinApp* myApp = AfxGetApp();
I get 'm_channelList' : is not a member of 'CWinApp' (which it obviously isn't), but if I use
CMyApp* myApp = AfxGetApp();
I get cannot convert from 'class CWinApp *' to 'class CMyApp *'.

Since your App it's actually a CMyApp (I guess you have, somewhere in you project, the following line: class CMyApp : public CWinApp), you can safely use the following cast:
CMyApp * myApp = (CMyApp*)AfxGetApp();
and the compiler will not complain anymore.

That worked perfectly, thanks! (And yes, my app class really is called CMyApp. LOL)

What I find is useful when I store info in MyApp is to add:
to MyApp.h
CMyApp* GetMyApp();
and for some common functions or global settings (if req'd)
void CommonAppFunction(something);
and to MyApp.cpp
CMyApp* GetMyApp()
{
return &theApp;
}
void CommonAppFunction(something)
{
return theApp.CommonAppFunction(something);
}
This enables you to write in any file that includes MyApp.h
GetMyApp()->DoSomething();
or
CommonAppFunction(something);
and saves all the casting etc.

You need to declare a CWinApp* variable, what you have there is a function prototype.
CWinApp* pApp = AfxGetApp();

Yeah, I picked up that little mistake when the compiler started throwing unexpected tokens at me LOL!

can anyone explain how to use tcp in C++ I've looked at a million sites and a million tutorials and every single one doesn't work.

What do you mean? Doesn't socket solve your questions? There are plenty good articles around socket here in CodeProject.

Good thing you came here then! There's plenty of articles available here and I bet most, if not
all, of them work
As mentioned, sockets is the easiest way to get started with TCP.

I've looked at many tutorials on this site. and none of them work(-_-") all the examples give compile errors

Hello everyone,
i am writing a program uses shared memory with semaphores and i use fork() mechanism for child process.
My program will run until the user hits ctrl+C.
But when it is hit, i must stop the child process, detach and deallocate the shared memory and then exit. How can i achieve this?
i tried signal and defined a handler function but i cannot pass any other necessary arguments to it. It takes only one int signum. Do u have any suggestions?
Thanks in advance.

How to make the edit control look like the format( : : : ) eg-> 12:15:03
There should be possibility of editing values but those colons should remain permanent.
any answers are appreciated.

Are you trying to store or present Time? Are you using MFC?
Why don't you use Date Time picker. Setting properties can display exactly such a control. If you need CString, it's as simple as using methods of the control(eg. str.Format("%02d:%02d:%02d", myTime.GetHour(), myTime.GetMin...); ). The control has also a Format function. If you are not going to show Time, then you can derive a new class from CEdit and overload it's painting function.
//This is not a signature
while (I'm_alive) {
cout<<"I Love Programming";

hi iam making a program to implement pwd command under unix environment.. but the result is always segmentation fault, i think my code is alright, can you give me a solution? thanks
#include<stdio.h>
#include<sys stat.h="">
#include<sys types.h="">
#include<pwd.h>
#include<dirent.h>
#include<grp.h>
#include<stdlib.h>
#include<string.h>
int main()
{
struct dirent *ds = 0;
DIR *dirp = 0;
struct stat sbuf;
char pathname[1024];
char *dirname;
struct passwd *pw;
struct group *gr;
dirname = ".";
dirp = opendir(dirname);
if(dirp)
{
strcpy(pathname,dirname);
strcat(pathname,"/");
strcat(pathname,ds->d_name);
lstat(pathname,&sbuf);
pw = getpwuid(sbuf.st_uid);
gr = getpwuid(sbuf.st_gid);
printf("%-8s \n",pw->pw_dir);
}
return(0);
}

You missed the forum (this is not Linux related).
Anyway I'll try to help you.
You forgot to allocate memory for ds variable. This may cause troubles to strcat(pathname,ds->d_name);.
Hope that helps

btw, what's a pwd command?
Press: 1500 to 2,200 messages in just 6 days? How's that possible sir?

From Linux man:
Pwd
Print the full filename of the current working directory.
