hi,
I need to find a way to get a list of all of the files in the current folder, so i thought i could have my program execute the 'dir' command into the command prompt and then parse what is returened.
would anyone have any ideas on how I could execute the 'dir' command from my program?

i found that system("dir"); works well.
You can call an external program with the system() function:
#include <stdlib.h>
system("DIR");But that's probably not what you want since you need the output. In that case, you need to create a pipe either through the Win32 API, or with a compiler extension if supported. For example, on Visual C++ .NET you would use SetCurrentDirectory to change the current working directory to the one you want, then _popen to create a pipe to the DIR program. After that it's just a matter of reading the FILE pointer returned by _popen just like any other stream:
#include <stdio.h>
#include <windows.h>
int main(void)
{
FILE *fp;
SetCurrentDirectory("C:\\");
fp = _popen("DIR", "r");
if (fp != NULL) {
char buffer[BUFSIZ];
while (fgets(buffer, sizeof buffer, fp) != NULL)
fputs(buffer, stdout);
}
return 0;
}thanks, but the following works good enough
void listDatFiles()
{
cout <<endl << "All .dat files in this folder are as followed:" << endl << "-----------------------" <<endl;
system("dir *.dat /B /O N");
