File Search Path

Anonymous — Thu, 08 Dec 2011 12:14:23 GMT

Hi,

I'm looking for some code that allows me to find files the same way AutoCAD does, by searching in the folders specified in the Support File Search Path.

Thanx,

Marc

Hi,

not tried, just searched through the object-catalog in vs ... and found:

Public MustOverride Function FindFile(fileName As String, database As Autodesk.AutoCAD.DatabaseServices.Database, hint As Autodesk.AutoCAD.DatabaseServices.FindFileHint) As String
Member von Autodesk.AutoCAD.DatabaseServices.HostApplicationServices

Sounds like that may be what you are searching for.

The other way would be using LISP (findfile "myFileName.ext")

HTH, - alfred -

1. get the AcadSearchPath:

           AcadPreferences acadPrefs = (AcadPreferences)Application.Preferences;
            string supportPath = acadPrefs.Files.SupportPath;
    //supportPath="path1;path2;path3..."

2.parse that string into an array of non empty pathnames

string[] searchPaths = supportPath.Split(new char[] { ';' }, StringSplitOptions.RemoveEmptyEntries).ToArray<string>();

3. sample 1 search for A folder

string menuPath = searchPaths .Where(name => name.ToUpper().Contains("TheFolderName")).First<string>();

Now the search for files

4. create the FindFile (overloaded) methodes, using the above searchPaths as a default

       public string AcadFindFile(string fileToFind)
        {

            AcadPreferences acadPrefs = (AcadPreferences)Application.Preferences;
            string[] pathsToSearchIn = acadPrefs.Files.SupportPath.Split(new char[] { ';' }, StringSplitOptions.RemoveEmptyEntries).ToArray<string>();

            return AcadFindFile(fileToFind, pathsToSearchIn);
        }

        public string AcadFindFile(string fileToFind, string[] pathsToSearchIn)
        {
            string fileFound = "";

                        if (Path.IsPathRooted(fileToFind))
            {
                if (File.Exists(fileToFind))
                    return fileToFind;

                fileToFind=Path.GetFileName(fileToFind);
            }

            var initialFolderList = pathsToSearchIn.ToArray<string>();
            var existingFolderList = initialFolderList.Where(path => new DirectoryInfo(path).Exists);
            foreach (var path in existingFolderList)
            {
                string fileFound2 = path..GetFiles(dir, fileToFind).First<string>();
            }
            var allfileList = existingFolderList.Select(dir => Directory.GetFiles(dir,fileToFind).First<string>());
            var matchingfileList=allfileList.Where(x => x.ToString().ToLower().Contains(fileToFind.ToLower()));
            var firstfile=matchingfileList.ToArray()[0];

            var dirQuery = pathsToSearchIn.Where(dir => Directory.Exists(dir))
                .Select(dir => Directory.GetFiles(dir).Where(x => x.ToLower().Contains(fileToFind.ToLower())));
            //var filesQuery = InitialFolderList.Where(dir=> File.Exists(dir));

            return fileFound;
        }

5. usage of the AcadFindFile methodes

string theFile = AcadFindFile("lib_G-H_B.dwg");

if (theFile.Length>0 )
ed.WriteMessage("\n{0}", theFile);

you'll need the following:

using System;
using System.IO;
using System.Collections.Generic;
using System.Linq;
using System.Text;

using Autodesk.AutoCAD;
using Autodesk.AutoCAD.Interop;
using Autodesk.AutoCAD.ApplicationServices;
using Autodesk.AutoCAD.Runtime;
using Autodesk.AutoCAD.DatabaseServices;
using Autodesk.AutoCAD.EditorInput;
using Autodesk.AutoCAD.Geometry;

Thank you for this input, but do you have the VB code too?

Some extra info;

The goal for my code is, I need to eccess a textfile for read that is stored in one of the folders that are defined in the search paths.

Hi,

>> but do you have the VB code too?

What source code do you need more than the 3 answers above gave you? First you search the file, then (if it's found) you open it .... what is missing?
