undocumented Shell32.dll calls

Author	Message
Tim Webbe #1 / 3	undocumented Shell32.dll calls In December 1998's copy of ".EXE" Dave Jewell give us an insight into the undocumented API calls in Shell32.dll. While I appreciate that you shouldn't use undocumented APis due to the possibility of them not being supported in future, I thought I'd give them a go. Now the article was written with Pascal programmers in mind but "it shouldn't be too hard to convert these calls to VB or C" As an example I tried to access the suggested "PickIconDlg" call. In the article Dave tells us this has the ordinal Number of 62. now I assume this is Hex, but I can't see ordinal D62 or H3E. Anyway I tried to convert his code and came up with the following. '----------------- Declare Function PickIconDlg Lib "shell32.dll" (howner As Long, ByVal sfile As String, max As Integer, ByVal iindex As Integer) As Boolean '----------------- not worrying for the moment about whether I've got the types of the parameters correct , of more pressing concern is that when called,. VB5 produced "can't find dll entry point pickicondlg in shell32.dll" what am I doing wrong? I even tried using pickicondlgA in vague desperation... please help! its got me going.... -- Tim Webber

Neila Ness #2 / 3	undocumented Shell32.dll calls Perhaps, Public Declare Function PickIconDlg Lib _ "shell32" Alias "#62" _ (ByVal szPath As String) As Long Never tried it, con't think I wanna mess around with undocumented API calls except when I am bored after 12 beers and have totally backed up my system ;-) Neila Quote: >In December 1998's copy of ".EXE" Dave Jewell give us an insight into the >undocumented API calls in Shell32.dll.
