FileFindFirstFile multiple extension

[hot202]

is there anyway to use FileFindFirstFile with multiple extension so i can use it to find say .jpg and .bmp?

[Tvern]

I don't think you can. However if you just make it return any file it's easy to then check for multiple extentions with StringRegExp().

[hot202]

so i would do a IF in the while loop? to see if its a .bmp or a .jpg?

[Tvern]

Yeah and then you can just Continueloop if the extention doesn't match.

i cant seem to get it working

$search = FileFindFirstFile($nm_dir & '\' & $event_value & "\" & "*.*")
                        If $search = -1 Then
                            MsgBox(0, "Error", "No files/directories matched the search pattern")
                            Exit
                        EndIf
                        While 1
                            $file = FileFindNextFile($search)
                            If @error Then ExitLoop
                            $ConstR = StringRegExpReplace($file, "^.*\\", "")
                            $test = StringMid($ConstR, StringInStr($ConstR, ".") + StringLen("."))
                            Switch $test
                                Case "bmp"
                                    MsgBox(1,"test",$file & ".bmp")
                                Case "jpg"
                                    MsgBox(1,"test",$file & ".jpg")
                            EndSwitch
                        WEnd
                        FileClose($search)

Try one of the following with the return from FileFindNextFile():

StringRegExp($file, ".*(bmp|jpg)\z") ;Returns 1 if *.bmp, or *.jpg. Returns 0 if not.
StringRight($file,4) ;Returns the last 4 characters of the filename for use with your switch. (add a period to your comparrison strings though)

You might want to double check to make sure you don't get a possitive on a folder it it has .jpg, or .bmp at the end. (daft I know)

Breakdown of the pattern:

".*(bmp|jpg)\z"
1: .            ;match any character
2: *            ;repeat 1 zero, or more times
3: (bmp|jpg)    ;match bmp Or JPG (I'm not sure how or knows what's part of the statements so I put brackets around it just to be sure. Seems to work without)
4: \z           ;match at end of file only.

thank man

i wasnt sure about using StringRight($file,4) incase the extension is more then 3 but there aint any in windows are there.

There are plenty of longer extensions (docx, xlsx, java, etc), but as long as you don't want those extentions to return a match that doesn't matter.

edit:

If you want to return the full extention regardless of length you can use:

$pos = StringInStr($file, ".", 0, -1) ;search for last period
If $pos Then ;file has an extention
    $test = StringRight($file, StringLen($file) - $pos) ;get the extention
Else
    $test = "" ;create a blank string if the file has no extention
EndIf

Note that this doesn't return the leading "." as it's not needed anymore.
