source: trunk/dll/defview.c@ 1780

Last change on this file since 1780 was 1780, checked in by Gregg Young, 11 years ago

Fixed errors found by cppcheck. Most had the potential to cause difficult to reproduce traps. Also fixed retry code for failure to create an archive work directory and the failure of the mailto code to drop trailing >.

11 20 Nov 03 SHL ShowMultimedia: try to convince fmplay to not play exes (Gregg Young)
12 14 Jul 06 SHL Use Runtime_Error
13 18 Mar 07 GKY Fixed misindentifycation of nonmultimedia files by ShowMultiMedia
14 18 Mar 07 GKY Open mp3, ogg & flac files with OS2 object default since fm2play fails
15 21 Apr 07 GKY Find FM2Utils by path or utils directory
16 09 Jun 07 SHL ShowMultimedia: Initialize hwnd so that OpenObject might work
17 20 Aug 07 GKY Move #pragma alloc_text to end for OpenWatcom compat
18 20 Dec 07 GKY Open jpg files with OS2 object default since image.exe fails
19 29 Feb 08 GKY Refactor global command line variables to notebook.h
20 25 Aug 08 GKY Check TMP directory space warn if lee than 5 MiB prevent archiver from opening if
21 less than 10 KiB (It hangs and can't be closed)
22 05 Jan 09 GKY Use TestBinary so that text viewer isn't used for hex files by default
23 08 Mar 09 GKY Additional strings move to PCSZs
24 15 Nov 09 GKY Add check for attempt to open zero byte file and reorder file type checks
25 to place exes before MMPM check (avoids MMPM trying to play them)
26 15 Nov 09 GKY Work around MMIO's falure to identify MPG files as media
27 12 Dec 09 GKY Remove code that opened files to check if they were media types
28 It was redundant.
29 12 Dec 09 GKY Pass .WPI files to PM for default handling.
30 02 Jan 12 GKY Completely rework ShowMultimedia to only test and try to open files with known multimedia extensions
31 This fixes some traps in GBM.DLL and PMCTLS.DLL; mmioIdentifyFile appears to pretty much be broken.
32 28 Jun 14 GKY Fix errors identified with CPPCheck
