|Summary||0003497: Memory leak in JvDriveCtrls|
|Description||JvDriveCtrls uses the function SHGetFileInfo, in some instances with the SHGFI_LARGEICON, SHGFI_SMALLICON, SHGFI_ICON which returns an icon handle in the hICON member of the SHFILEINFO structure.|
It is not being freed -- this causes a system crash when using JvDriveCtrls to build a list of files/directories on a drive with a very large number of files present.
The info below is taken from http://msdn.microsoft.com/library/default.asp?url=/library/en-us/shellcc/platform/shell/reference/functions/shgetfileinfo.asp
"If SHGetFileInfo returns an icon handle in the hIcon member of the SHFILEINFO structure pointed to by psfi, you are responsible for freeing it with DestroyIcon when you no longer need it."
|Tags||No tags attached.|
Yes, but we use it with the SHGFI_SYSICONINDEX flag, which, to me, means that the Icon is shared and as such should not be destroyed.
However, it may happen that SHGFI_SYSICONINDEX is not always used, in which case there is a potential memory leak.
||Ok, SHGFI_ICON was set in three different places, where it should not have been. This is now fixed.|
