| 1 | A list of Open32 bugs (under construction):
|
|---|
| 2 |
|
|---|
| 3 | - Key mapping problem. Cursor key messages (WM_KEYUP/DOWN) contain the wrong
|
|---|
| 4 | OEM scancode (should be the same as the numeric keypad arrow keys)
|
|---|
| 5 | Make that: extended key mappings are totally messed up
|
|---|
| 6 | - No support for CBS_OWNERDRAWFIXED or CBS_OWNERDRAWVARIABLE styles (COMBOBOX)
|
|---|
| 7 | - Crash in PMWINX if the app isn't PM
|
|---|
| 8 | - Open32 isn't sending WM_NCCREATE msgs
|
|---|
| 9 | - HK_CBT hook not supported
|
|---|
| 10 | - HK_GETMESSAGE hook crashes in PMWINX
|
|---|
| 11 | - UpdateWindow sends a WM_ERASEBKGRND when it shouldn't
|
|---|
| 12 | - Open32 doesn't send a WM_ERASEBKGND when a window is activated
|
|---|
| 13 | - HeapCreate with dwMaximumSize == 0 seems to reserve only 64 kb memory
|
|---|
| 14 | instead of 'unlimited'. Makes Win32 heaps impossible to use.
|
|---|
| 15 | - CreateDialogParamA can have a dlgproc set to NULL -> PMWINX crash
|
|---|
| 16 | - GetObject doesn't return the pointer to the bitmap data (always 0)
|
|---|
| 17 | - GetFileType returns FILE_TYPE_UNKNOWN for file handles
|
|---|
| 18 | - WriteFile with nrbytes = 0 should SetEndOfFile Open32 does not. (Notepad95)
|
|---|
| 19 | - GetDeviceCaps -> NT returns -1 when using 16 bits colors, NOT 65536!
|
|---|
| 20 | - File handles returned by _lopen & _lcreate are 32 bits; Windows returns
|
|---|
| 21 | handles with only the least significant 16 bits filled.
|
|---|
| 22 | - Wrong calling convention for Win32 apis (_System instead of _stdcall or for
|
|---|
| 23 | some apis _cdecl)
|
|---|
| 24 | - Wrong calling convention for callback handlers (_System instead of _stdcall)
|
|---|
| 25 | - Wrong calling convention for hook handlers (_System instead of _stdcall)
|
|---|
| 26 | - RegOpenKeyEx doesn't set the HKEY pointer (5th argument) to zero when an
|
|---|
| 27 | error occurs. Some applications depend on this to do error checking.
|
|---|
| 28 | - RegSetValueA crashes in pmwinx.dll if the size parameter is 0 and the string
|
|---|
| 29 | is very large.
|
|---|
| 30 | - CreateDIBSection does not flip bitmaps is vertical or horizonal size is
|
|---|
| 31 | negative.
|
|---|
| 32 | - Default window message handlers (i.e. DefWindowProcA) don't properly support
|
|---|
| 33 | some messages (i.e. WM_CTLCOLOR*)
|
|---|
| 34 | - GetSystemMetrics far from complete
|
|---|
| 35 | - SystemParametersInfoA incomplete
|
|---|
| 36 |
|
|---|
| 37 | Limitations:
|
|---|
| 38 | - No support for COMCTL32 controls.
|
|---|
| 39 | - Many Win32 apis not included.
|
|---|
| 40 | - Many apis have extensions in Win9x & NT 4 that are not supported.
|
|---|
| 41 | - No support for Win9x & NT 4 extended dialog styles.
|
|---|
| 42 | - Profile apis don't use ini files.
|
|---|
| 43 |
|
|---|
| 44 | General problem:
|
|---|
| 45 | - Can't extend Open32 easily without knowledge of internals
|
|---|
