Searching Edit component with autocomplete for Directory/Files

[Carlo Barazzetta 112]

I'm searching for an "autocomplete editing" component (showing a list of possibilities) of available directories/filenames based on typed text, for an OpenSource project, so I need an OpenSource component that makes this work...
Any suggestion?
Thanks.

Not a component but a function that adds this functionality to any TEdit:

I've some problems using dzlib with Delphi11:
1) An AV inside TEnumStringFiles.Next
2) don't compile with 64bit platform
Is this version the latest?

Thanks.

Does a TCombobox, with the Items list filled with the available files, not fit your need?

Why implement a custom IEnumStrings class for directories/files?  There is already a pre-made data source provided by the OS for that exact purpose - CLSID_ACListISF, which can be created with CoCreateInstance(), configured via IACList2::SetOptions(), and then passed to IAutoComplete::Init().

Does that one also allow pre-filtering the filenames? e.g. If I only want to select from GX_*.pas files, or those matching *.dbf;*.dat ?

I already had a similar function for filenames and directories without filtering using SHAutoComplete, but the filtering was important for me.

 

(Short answer: I didn't know about this)

Ah.  No, it does not.  In that case, you would indeed need a custom enumerator.
