OpenAs_RunDLL vs. SHOpenWithDialog

[katayama_hirofumi_mz]

Hello, everyone!

I'm trying to implement Folder Options. It needs the "Open With" dialog. After investigation, I found the possible candidates are OpenAs_RunDLL and SHOpenWithDialog functions.

SHOpenWithDialog
https://msdn.microsoft.com/en-us/librar ... 62234.aspx

SHOpenWithDialog is Vista+, so Windows Server 2003 doesn't have implementation of SHOpenWithDialog function. However ReactOS have a limited SHOpenWithDialog implementation.

On the other hand, OpenAs_RunDLL is not documented. ReactOS doesn't no implementation of OpenAs_RunDLL.

To implement Folder Options, we have to use either OpenAs_RunDLL or SHOpenWithDialog function. I cannot analyse it deaply. I can use API Monitor for my analysis, but cannot use OllyDbg yet.

What should we do?

Can we "steal" it from Wine maybe?

No. There is no SHOpenWithDialog nor OpenAs_RunDLLW implementations in Wine.

If we use SHOpenWithDialog for ReactOS Folder Options, then its API would target Vista+ and we have to test SHOpenWithDialog against Vista+. We cannot test SHOpenWithDialog in win2k3.
