Hello,

You might incorporate the built in DIALOG_PICKFILE function into your own reader.
Something like the following might do it.

;-----------
FUNCTION READ_ThisData, File, Group = Group, Cancel = Cancel

Cancel = 0
If N_Elements(File) EQ 0 Then Begin
File = Dialog_PickFile(Group = Group)
; if user cancels then return -1 and set the cancel flag
If File[0] EQ '' Then Begin
Cancel = 1
Return, -1
EndIf
EndIf

.... Your other stuff here to read in the data ...

Return, ThisData

END
;-----------------

The other way to work around this is don't use DIALOG_READ_IMAGE function. Use
the DIALOG_PICKFILE function, then read in the data based upon which type of
format the user chooses. You can use the result of QUERY_IMAGE to determine if
the image is a 'standard' image format according to IDL's definitions.

Good luck,

Ben
