File list. Recursively searching folders.

[Sidar]

Like I said before, the method had no problem finding my file in a SUBFOLDER. Even now that seems to stop working even though I didn't change anything.

sorry but you are not getting the point.

filelist only owns this files.

Code: Select all

 
u32 max=filelist->getFileCount();
(u32 i=0; i<max; i++)
{
    cout<<filelist->getFileName(i).c_str()<<endl; 
}
 

it is obvious that if file list has following files

folder/a.png
folder/b.png
folder/c.png

it is not able to find

folder/folder/a.png

because since you are concatenating filenames you are exactly trying to search for files that are not in filelist. As already sad your problem is that filelist->Findfile
was returning -1. I just pointed you because findfile was returning -1.

If you want really to find "folder/folder/a.png" you should find someway to add that file to the filelist (initializing correctly the file list could be a way, you can add later all paths i thnik also) or to use another filelist, because filelist is not automagically updating its content. It's just a list (of files but nothing more than a list).

so the first thing you need to see is what files are inside filelist. You will know this way if the problem is the filelist or something else

Yeah I figured that much.

This is hopeless I'm working on this far too long. All I really wanted is to look for a file in a given path and all it's subfolders.
But I can't figure it out.

I guess I have to try a different approach.
thanks anyways.


Edit:

Removed the Irrlicht filelist and just went with the windows API.

Code: Select all

irr::video::ITexture * TextureManager::findInPath(irr::io::path path,irr::io::path filename){
 
        irr::video::ITexture * t = NULL;
        irr::io::path dir(path);
        dir.append("*");
        WIN32_FIND_DATA file;
        HANDLE search_handle=FindFirstFile(LPCTSTR(dir.c_str()),&file);
 
        
        if (search_handle)
        {
 
                do
                {
                        irr::io::path resultPath;
                        if (file.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY)
                        {
                                
                                //Skip any reference to current or parent folder. Else inf-loop imminent
                                if(file.cFileName[0] == '.'){
                                        continue;
                                }
                                        t = findInPath(path+file.cFileName + "/",filename);
                                        if(t) return t;
                        }
                        else
                        {
                                
                                irr::io::path sfile(file.cFileName);
 
                                std::cout << sfile.c_str();
 
                                if(sfile.equals_ignore_case(filename) == true)
                                {
 
                                        resultPath = path + filename;   
                                        t = driver->getTexture(resultPath);
                                        return t;
                                }
                        }
 
                }while(FindNextFile(search_handle,&file));
 
                FindClose(search_handle);
 
        }
        return t;
};

This works.
Now if only I could find a way to sort the items on files first.

I tried changing work directory before my solution, it gave all sort of problems with other objects trying to find files.
Of course it's just me not fully grasping everything in C++ and such.

Here is slightly better "solution" with the win32 api.

Code: Select all

irr::video::ITexture * TextureManager::findInPath(irr::io::path path,irr::io::path filename){
 
        irr::video::ITexture * t = NULL;
        irr::io::path dir(path);
        dir.append("*");
 
        irr::io::path currDir(path);
        currDir.append(filename.c_str());
 
        WIN32_FIND_DATA file;
        HANDLE search_handle=FindFirstFile(LPCTSTR(dir.c_str()),&file);
        irr::io::path resultPath;
 
        if(GetFileAttributes(LPCTSTR(currDir.c_str())) != 0xFFFFFFFF)
        {
                resultPath = path + filename;   
                t = driver->getTexture(resultPath);
                return t;
        }
 
        else if (searchRecursively == true && search_handle)
        {
                do
                {
                        
                        if (file.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY)
                        {
                                
                                //Skip any reference to current or parent folder. Else inf-loop imminent
                                if(file.cFileName[0] == '.')
                                {
                                        continue;
                                }
                                        t = findInPath(path+file.cFileName + "/",filename);
                                        if(t) return t;
                        }
                
                }while(FindNextFile(search_handle,&file));
 
                FindClose(search_handle);
 
        }
        return t;
};

It first checks if the file im looking for exists in the folder, then it continues iterating over every folder and calls itself again.

Thanks for the help though. But for now this will suffice =D
