2 problems in ComDlg32

[Borje Hagsten]

I like to lift out the OpenFileDialog function from COMDLG32.INC and
do own stunts there, different depending on app'. Then, no problem to
let a global var store the returned nFilterIndex member, etc. Another
advantage - one can also decide filter index on opening.

Know you already know all this stuff, but in case you still want to
see, and for eventual lurkers - in my editor control sample I lift out
those functions for desired index selection, etc.

It also shows proper way to handle Save dialog in 32-bit Windows. Save
dialog must never have dual file prefixes per filter index, because then file
will end up with double file ends (like PBedit's mycode.bas.inc, for example)

See http://www.tolken99.com/edm32.zip (117KB)

Oh yes - Should think the limit is the limit of what a combo box can handle,
so should be possible to use as many as one needs (would be fun to release a
good text editor with 32000 file types to chose from - all in random order..

Eh, what was the question again (typical me - answer, but don't read question)
The OpenFileDialog function can be modified to own needs. No problems to add
a BYREF FilterIndex member to it, but best is to lift out function and do own
version inside code, something like:

FUNCTION MyOpenFileDialog (BYVAL hWnd AS DWORD, _           ' parent window
                           BYVAL Caption AS STRING, _       ' caption
                           Filespec AS STRING, _            ' filename
                           BYVAL InitialDir AS STRING, _    ' start directory
                           BYVAL Filter AS STRING, _        ' filename filter
                           BYVAL DefExtension AS STRING, _  ' default extension
                         FilterIndex AS DWORD              '<- NOTE: added!
                           Flags AS DWORD ) AS LONG         ' flags
 
'..
'..
  FUNCTION = GetOpenFilename(ofn)
 
  FilterIndex = ofn.nFilterIndex
'..

In GetOpenFileName?
Filterindex is returned in OPENFILENAME structure

lpStrFilter has no published limitation on size.

Or are you talking about the OpenFileDialog function PB wrote as a wrapper for GetOpenFileName? If this, just modify it.

1) Already mentioned, can the selected filterindex be returned? (byref)
2) I use quite a lot of filter entries, the asciiz is limmited, i copied this code and adapted it.
The filter is now~2k
Can this be increased, i like to use the PB stuff instead.

Thanks,
