'-------------------------------------------------------------------------------
' Wishes :
' Use this routine, and if you make it better, please mail me your new release.
' Best regards
' -------------------------------------------------------------------------------------------
' Returns a value of variant type
'
' WildCards (*?) available in file and directory names
'
' Returns a value < 0 : an error occured. Value returned is Err.Number * -1
'
' Tasks :
' Test if a file exists : if FCount("C:\MyPath\TEST.TXT")>0 then...
' Count how much files exist : lngNbOfFiles = FCount("C:\*.TXT")
' Test if a directory exists : if FCount(strPath,vbdirectory)>0 then...
' Test if a hidden directory exists : if FCount(strPath,vbDirectory + vbHidden)>0 then...
' Get Total Size of files in a directory : dblTotalSize = FCount("C:\MyPath\*.*",,true) ' vbNormal + vbReadOnly + vbHidden + vbSystem files included
' Get Total Size of .TXT files in a dir : dblTotalSize = FCount("C:\MyPath\*.TXT", vbNormal,,true) ' vbReadOnly + vbHidden + vbSystem files excluded
' Get a string of all filenames in a dir : strMyFiles = FCount("C:\MyPath\*.*",,,true) ' filenames are separated by vbCr
' Get an array with .TXT filenames in a dir : aMyArray = split(FCount("C:\MyPath\*.TXT",,,true), vbCr)
'
' and so on...
