;----------------------------------------------------------------------------------------------
; Function: FileOpen
; Display standard OpenSaveDialogue
;
; Parameters:
; HWND - Parent's Handle
; Filter - Specify Filter as with FileSelectFile
; for use of multiple Filter seperate them with |
; defaultFilter - Selects default Filter from above List
; IniDir - Specify Initialisation Directory
; chosen Directory will be set as WorkingDir in
; A_WorkingDir
; DialogTitle - Dialogue Title
; defaulltExt - Extension to append when none given
; flags - Flags for Dialogue
; when no supplied
; OFN_FILEMUSTEXIST - OFN_HIDEREADONLY - OFN_ENABLEXPLORER
; are used as default
;
; Returns:
; Selected FileName or Emtpy when cancelled
;
; Remarks:
; When OFN_ALLOWMULTISELECT flag is set, be sure to set OFN_ENABLEXPLORER flag,
; too. Without it the Old-Style FileOpen Dialogue appears and handling multiple
; fileNames might be different and wont work as expected
; See http://msdn2.microsoft.com/en-us/library/ms646839.aspx for details
