Thread: Lb_dir

Hi all;

Okay i have set a list box to read all the files and navigate through directorys. But all i want to do is navigate the directories and only display *.avi files.

When i do this
SendMessage (FilesLST, LB_DIR, DIR,
(LPARAM) TEXT ("*.avi")) ;

only drives come up, so i have to use *.* and list everthing iside the dir. Any advise? thanks heaps.

BOOL IsFileWithExt(char *file,char *ext)
{
int i=0;
char ex[5]="";
for(i=(int)strlen(file);i>0;i++)
{
if(file[i]!='.')
sprintf(ex,"%s%c",ex,file[i]);
else
break;
}
strcpy(ext,strrev(ext));
if(!strcmpi(ext,ex))
return TRUE;
else
return FALSE;
return FALSE;
}

void EnumFiles(HWND listbox,char *directory,char *ext,BOOL subdirs,BOOL showfullpath,BOOL byext,BOOL showdirs)
//listbox - handle to listbox windows
//directory - path to search in
//ext - extension (exe or *) - used only with byext=TRUE
//subdirs - look in subdirs too
//showfullpath - enter the full path in the listbox or only the file name
//byext - ignore files not matching extension
//showdirs - insert the directories in the listbox , not only files

{

here's a snippet from a MP3 player I made a while ago...

Code:

	char pathname[255]={0};
	struct _finddata_t fileinfo;
	long findhandle;
				GetDlgItemText(hwnd, IDC_FOLDER, pathname, 255);
				strcat(pathname,"*.mp3");

				findhandle = _findfirst(pathname,&fileinfo);

				if (findhandle==-1)
				{
					MessageBox(NULL, "Directory Not Found", "Error", MB_OK);
					return FALSE;
				}
				SendMessage(hwndList, LB_ADDSTRING, 0, (LPARAM)fileinfo.name);
				while(_findnext(findhandle,&fileinfo)==0)
				{
					SendMessage(hwndList, LB_ADDSTRING, 0, (LPARAM)fileinfo.name);
				}

It's a lot better than using LB_DIR because it gives the full filename, not just the DOS version.
