File Type Finder

Post subject:  File Type Finder
I made a program that reads files in a folder and puts them into an array...:

code:

var streamNumber : int
var size, attribute, fileTime : int
var fullFileName, fileLength : string := ""
var Semicolon : int := 0
var fileNum := 1

var Folder : string := "New Folder"

proc LoadFile
    fileLength := ""
    streamNumber := Dir.Open (Folder)

    assert streamNumber > 0

    loop
        Dir.GetLong (streamNumber, fullFileName, size, attribute, fileTime)
        exit when fullFileName = ""
        fileLength := fileLength + fullFileName + ";"
    end loop

    Dir.Close (streamNumber)
end LoadFile

LoadFile

for i : 1 .. length (fileLength)
    if fileLength (i) = ";" and fileLength (i + 1) not= chr (46) then
        fullFileName := fileLength (i + 1 .. *)
        exit
    end if
end for

for i : 1 .. length (fileLength)
    if i < length (fileLength) then
        if fileLength (i) = ";" and fileLength (i + 1) not= chr (46) then
            Semicolon := Semicolon + 1
        end if
    end if
end for

put "Files Found: ", Semicolon
put "-------------------------"

var fileNames : array 1 .. Semicolon of string
var fileName : array 1 .. Semicolon of string

for i : 1 .. Semicolon
    fileNames (i) := ""
    fileName (i) := ""
end for

for a : 1 .. length (fullFileName)
    if fullFileName (a) = ";" then           % Next File
        fileNum += 1
    else
        fileName (fileNum) += fullFileName (a)
    end if
end for

for i : 1 .. Semicolon
    put fileName (i)
end for


anyway I could make that shorter?

Here is an update, this finds .exe files... you could change that to any other file types of course if your going to make a paint program that allows to only view one file type... It's very useful..
Just make the a folder called "New Folder" in the same folder that you save this.. and make a bunch of file types.. and some .exe files, when you run it he'll read all the file names and add them into an array, from that array it reads all the file names and picks out .exe files...

code:

var streamNumber : int
var size, attribute, fileTime : int
var fullFileName, fileLength : string := ""
var Semicolon : int := 0
var fileNum := 1
var exeFound := 0

var Folder : string := "New Folder"

proc LoadFile
    fileLength := ""
    streamNumber := Dir.Open (Folder)

    assert streamNumber > 0

    loop
        Dir.GetLong (streamNumber, fullFileName, size, attribute, fileTime)
        exit when fullFileName = ""
        fileLength := fileLength + fullFileName + ";"
    end loop

    Dir.Close (streamNumber)
end LoadFile

LoadFile

for i : 1 .. length (fileLength)
    if fileLength (i) = ";" and fileLength (i + 1) not= chr (46) then
        fullFileName := fileLength (i + 1 .. *)
        exit
    end if
end for

for i : 1 .. length (fileLength)
    if i < length (fileLength) then
        if fileLength (i) = ";" and fileLength (i + 1) not= chr (46) then
            Semicolon := Semicolon + 1
        end if
    end if
end for

put "Files Found: ", Semicolon
put "-------------------------"

var fileName : array 1 .. Semicolon of string
var fileType : array 1 .. Semicolon of string

for i : 1 .. Semicolon
    fileName (i) := ""
end for

for i : 1 .. Semicolon
    fileType (i) := ""
end for


for a : 1 .. length (fullFileName)
    if fullFileName (a) = ";" then           % Next File
        fileNum += 1
    else
        fileName (fileNum) += fullFileName (a)
    end if
end for

put Semicolon

for b : 1 .. Semicolon
    for a : 1 .. length (fileName (b))
        if fileName (b) (a) = "." then    % Next File
            fileType (b) := fileName (b) (a .. *)
        end if
    end for
end for

for i : 1 .. Semicolon
    put fileName (i)
end for
put "-----------"

for i : 1 .. Semicolon
    if fileType (i) = ".exe" then
        exeFound := exeFound + 1
    end if
end for

put ".exe Files Found: ",exeFound


again if you find a way to shorten this please share..

Ok... I ran it but I got an error...

dynamic array upper bound is less than lower bound

I take it that only happens if no files are found right?... well you should really fix that


ummm... this is a little shorter.... but its only part of it... paste it over everything from put "Files Found:",Semicolon to the end


code:
put "Files Found: ", Semicolon
put "-------------------------"

var fileName, fileType : array 1 .. Semicolon of string
 

for i : 1 .. Semicolon
    fileName (i) := ""
    fileType (i) := ""
end for


for a : 1 .. length (fullFileName)
    if fullFileName (a) = ";" then           % Next File
        fileNum += 1
    else
        fileName (fileNum) += fullFileName (a)
    end if
end for

put Semicolon

for b : 1 .. Semicolon
    for a : 1 .. length (fileName (b))
        if fileName (b) (a) = "." then    % Next File
            fileType (b) := fileName (b) (a .. *)
        end if
    end for
    put fileName (b)
        if fileType (b) = ".exe" then
        exeFound := exeFound + 1
    end if

end for
put "-----------"
put ".exe Files Found: ",exeFound
