File.Find Filters

[yhb]

Is it posibble to use a filter for File.Find ? like if I want to find only (*aa.pdf, *.bb.pdf, *cc.pdf) instead of using a wildcard like below?

File.Find(tFolder, "*.*", false, false, nil, nil);

Thanks much... :

Something like *.file?*.lulz

Don't think that works.

its possible but youd have to use regex in lua or use my free dll RegXmATCH. I was working on a similar type of project some time ago to create a custom compression application and needed to filter the file types.

Filename
(string) The name of the file that you want to search for. You can use the * and ? wildcards in this field to search for files that match a specific pattern.

You can use wildcards, no need for a DLL.

hi yhb

hi yhb and all. i write some func maybe these can help you :

Global Functions:

function DelimitedStringToTable(DelimitedString, Delimiter)
	tbReturn = {};
	local strWorking;
	local nPos = nil;
	local strData;
	local nTableIndex = 1;
	local nDelimiterLength = String.Length(Delimiter);
	
	if(nDelimiterLength < 1)then
		tbReturn[nTableIndex] = DelimitedString;
		return tbReturn;
	end
	
	strWorking = DelimitedString;
	nPos = String.Find(strWorking,Delimiter);
	while(nPos ~= -1)do
		strData = String.Left(strWorking,nPos-1);
		tbReturn[nTableIndex] = strData;
		nTableIndex = nTableIndex + 1;
		local nLength = String.Length(strWorking);
		strWorking = String.Right(strWorking,nLength - (nPos + (nDelimiterLength-1)));
		nPos = String.Find(strWorking,Delimiter);
	end
	if(strWorking ~= "")then
		tbReturn[nTableIndex] = strWorking;
	end
	
	return tbReturn;
end


function FilesFind (files, drives)

a = 0
my_table = DelimitedStringToTable(files, "|")
fix = DelimitedStringToTable(drives, "|")
allfolder_files = {}

for count,drive in fix do
   
   for index,file in my_table do
    foundfile = File.Find(drive, file, true, false, nil, nil);

     if (foundfile ~= nil) then 
      
      for f,g in foundfile do
       a=a+1
       Table.Insert(allfolder_files, a, g);
      end
     
     end
   
   end

end

	return allfolder_files
end

for call this func you must write files with | for first parameter an Folders with | for Second parameter. for example :

tbl = FilesFind ("*.pdf*|*.exe*|*.bmp*|*a.avi", "g:\\pdfs|f:")

for a,b in tbl do
	ListBox.AddItem("ListBox1", b, "")
end

in this examp search *.pdf* and *.exe* and *.bmp* and *a.avi in g:\pdfs and f:\

Enjoy.

I think it's just *.file,*.fileext2 or *.ext|*.lol

hey shadow i found the only reason i needed to use regex was for to filter multiple file extensions for the same type of file and perform an action based upon it. [mainly for imagelist]

Like when u have spanned rar files such as .rar, .r01, .r02, ect

Hey PEM, Thank you so much.... it works GREAT. Exactly what I'm looking for. I appreciate this a lot.

Thank you again..
