Searching for a file using FindFirstFile() ?

I know salem has discussed this before, but I am using LCC-Win32 at the moment and need to find out how to search the entire hard drive for sol.exe (solitare).

Here's a snippit of code that works with my compiler:

Code:

---

int findSolitaire(void)
{
 WIN32_FIND_DATA solitaire;
 FindFirstFile("sol.exe",&solitaire);
 MessageBox(NULL,solitaire.cFileName,solitaire.cFileName,0);
 return 0;
}

---

This only works if solitaire is in THE SAME DIRECTORY as the running program. Please post an example of one that searches the entire hard drive.

PS: chdir() doesn't work in my compiler (LCC is C-Only, so C++ functions don't work)

I was wondering the same question before, but you might try this:


WIN32_FIND_DATA solitaire;

FindFirstFile ("C:\*.*\sol.exe", &solitaire);

I'm not sure it works, but you can try it.

yeah but if that works I still wont get the full path. Oh - and it doesn't work.

I didn't see that part. Well, you can try GetFullPathName(), but I don't know how to use it. Look for it at MSDN. It shows the parameters for it.

Helpful, but you still need to have found the file before GetFullPathName is of any use.

FindFirstFile() returns directories aswell as files. The file attribute (dwFileAttributes) returned in the WIN32_FIND_DATA struct will contain the FILE_ATTRIBUTE_DIRECTORY flag. When you encounter a directory you could recursively call your file searching function with the directory that you've found appended to your existing path.

Please give an example, I'm dumb :(.

I've not done alot of testing (and it is a quick hack), but this appears to work -

Code:

---

#include <stdio.h>
#include <string.h>
#include <windows.h>

void find(char* path,char* file)
{
        static int found =0;
        HANDLE fh;
        WIN32_FIND_DATA wfd;
        int i=0;
        int j=0;
        fh=FindFirstFile(path,&wfd);
        if(fh)
        {
                if(strcmp(wfd.cFileName,file)==0)
                {
                        path[strlen(path)-3]='\0';
                        strcat(path,file);
                        FindClose(fh);
                        return;
                }
                else
                {
                        while(FindNextFile(fh,&wfd) && found ==0)
                        {                               
                                if(strcmp(wfd.cFileName,file)==0)
                                {
                                        path[strlen(path)-3]='\0';
                                        strcat(path,file);
                                        FindClose(fh);
                                        found =1;
                                        return;
                                }
                                if(wfd.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY &&
                                        strcmp(wfd.cFileName,"..")!=0 && strcmp(wfd.cFileName,".")!=0)
                                {
                                        path[strlen(path)-3]='\0';
                                        strcat(path,wfd.cFileName);
                                        strcat(path,"\\*.*");
                                        find(path,file);
                                }
                        }
                       
                        if(found==0)
                                {
                                for(i=strlen(path)-1;i>0;i--)
                                {
                                        if(j==1 && path[i]=='\\')
                                        {
                                                path[i]='\0';
                                                strcat(path,"\\*.*");
                                                break;
                                        }
                                        if(path[i]=='\\')
                                                j=1;
                                }
                        }
                }
                FindClose(fh);
        }
               


}

int main()
{
        TCHAR path[512] = "C:\\*.*";
        find(path,"notepad.exe");
        printf("%s\n",path);
 
        return 0;
}
