Bug 86785

Description Tiberiu Caprita 2005-02-27 14:24:27 EST

A file Class may have specific Icons for every file, Windows then requiring in 
Registry a set as DefaultIcon=%1 . In such case, Program.findProgram(ext) 
doesn't get the Icon.
Sample:
this= Program  (id=33)
  command= ""C:\\Internet Explorer\\iexplore.exe" %1"
  iconName= ""%1""
  name= "HTML-Dokument"


Details (about .exe please see also Bug 61023):
I am interested in getting Icons of a file extensions (regardless if is a 
File which you can open or not), as it they are shown in Explorer. 

From how is written Program.getImageData() it is clear that is supposed
Program.iconName to be something as <FileName[,Nr]>

Program.getProgram() fills iconName with HKCR\<Class>\\DefaultIcon value.
Problem occurs when the file classes have Icon Handlers (see 
http://msdn.microsoft.com/library/default.asp?url=/library/en-
us/shellcc/platform/shell/programmersguide/shell_int/shell_int_extending/extensi
onhandlers/iconhandlers.asp
) and therefore DefaultIcon=%1 (to me is the case of .html) or by example when 
there is no DefaultIcon (.exe).
Then sure that getImageData() runs with wrong Input param.

Sometimes SWT Program doesn't find the default Action of a extension file 
(maybe even doesn't exist) -".dll" by example, so that Icon detection maybe 
would be better separate from Program instance.

In order to get Image Files, it is interesting to see if that ones couldn't be 
obtained with OleGetIconOfClass/OleGetIconOfFile (then will be nice to have 
these fct. in swt.dll).
