| [3811] | 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 if CBS_OWNERDRAWFIXED && !CBS_HASSTRINGS and sending CB_ADDSTRING with
|
|---|
| 8 | attached item data (i.e. PERFMON sends 0,1,2,3,4 and PM treats this item data
|
|---|
| 9 | as pointers)
|
|---|
| 10 | - Crash in PMWINX if the app isn't PM
|
|---|
| 11 | - Open32 isn't sending WM_NCCREATE msgs
|
|---|
| 12 | - HK_CBT hook not supported
|
|---|
| 13 | - HK_GETMESSAGE hook crashes in PMWINX
|
|---|
| 14 | - UpdateWindow sends a WM_ERASEBKGRND when it shouldn't
|
|---|
| 15 | - Open32 doesn't send a WM_ERASEBKGND when a window is activated
|
|---|
| 16 | - HeapCreate with dwMaximumSize == 0 seems to reserve only 64 kb memory
|
|---|
| 17 | instead of 'unlimited'. Makes Win32 heaps impossible to use.
|
|---|
| 18 | - CreateDialogParamA can have a dlgproc set to NULL -> PMWINX crash
|
|---|
| 19 | - GetObject doesn't return the pointer to the bitmap data (always 0)
|
|---|
| 20 | - GetFileType returns FILE_TYPE_UNKNOWN for file handles
|
|---|
| 21 | - WriteFile with nrbytes = 0 should SetEndOfFile Open32 does not. (Notepad95)
|
|---|
| 22 | - GetDeviceCaps -> NT returns -1 when using 16 bits colors, NOT 65536!
|
|---|
| 23 | - File handles returned by _lopen & _lcreate are 32 bits; Windows returns
|
|---|
| 24 | handles with only the least significant 16 bits filled.
|
|---|
| 25 | - Wrong calling convention for Win32 apis (_System instead of _stdcall or for
|
|---|
| 26 | some apis _cdecl)
|
|---|
| 27 | - Wrong calling convention for callback handlers (_System instead of _stdcall)
|
|---|
| 28 | - Wrong calling convention for hook handlers (_System instead of _stdcall)
|
|---|
| 29 | - RegOpenKeyEx doesn't set the HKEY pointer (5th argument) to zero when an
|
|---|
| 30 | error occurs. Some applications depend on this to do error checking.
|
|---|
| 31 | - RegSetValueA crashes in pmwinx.dll if the size parameter is 0 and the string
|
|---|
| 32 | is very large.
|
|---|
| 33 | - CreateDIBSection does not flip bitmaps is vertical or horizonal size is
|
|---|
| 34 | negative.
|
|---|
| 35 | - Default window message handlers (i.e. DefWindowProcA) don't properly support
|
|---|
| 36 | some messages (i.e. WM_CTLCOLOR*)
|
|---|
| 37 | - GetSystemMetrics far from complete
|
|---|
| 38 | - SystemParametersInfoA incomplete
|
|---|
| 39 | - GetWindowLong returns 0xffff for GWL_ID. This should be 0xffffffff.
|
|---|
| 40 | - Open32 doesn't send any WM_PARENTNOTIFY messages
|
|---|
| 41 | - Open32 doesn't send WM_SETCURSOR or WM_MOUSEACTIVATE to parent windows
|
|---|
| 42 | - CS_SAVEBITS: window movements are slow, many repaints
|
|---|
| 43 | - SetROP2 with R2_XORPEN doesn't work. Example:
|
|---|
| 44 | hOldPen = SelectObject (hdc, GetStockObject (BLACK_PEN));
|
|---|
| 45 | oldRop = SetROP2 (hdc, R2_XORPEN);
|
|---|
| 46 | MoveToEx (hdc, x, rect.top, NULL);
|
|---|
| 47 | LineTo (hdc, x, rect.bottom);
|
|---|
| 48 | SetROP2 (hdc, oldRop);
|
|---|
| 49 | SelectObject (hdc, hOldPen);
|
|---|
| 50 | - FillRect uses the wrong color sometimes; see menu code (MENU_DrawMenuItem)
|
|---|
| 51 | - Wrong return values for GetDIBits & SetDIBitsToDevice
|
|---|
| 52 | (nr of scan lines copied; not true/false)
|
|---|
| 53 | - SetDIBitsToDevice can't handle compressed bitmaps (presumably all other
|
|---|
| 54 | bitmap apis as well)
|
|---|
| [4600] | 55 | - Workaround added for bugs in Open32's SetDIBits; messes up colors for 1 bpp bitmaps
|
|---|
| 56 | (reversing scanlines and calling SetBitmapBits works, but only if the all scanlines are updated!)
|
|---|
| [3811] | 57 |
|
|---|
| 58 | Limitations:
|
|---|
| 59 | - No support for COMCTL32 controls.
|
|---|
| 60 | - Many Win32 apis not included.
|
|---|
| 61 | - Many apis have extensions in Win9x & NT 4 that are not supported.
|
|---|
| 62 | - No support for Win9x & NT 4 extended dialog styles.
|
|---|
| 63 | - Profile apis don't use ini files.
|
|---|
| 64 |
|
|---|
| 65 | General problem:
|
|---|
| 66 | - Can't extend Open32 easily without knowledge of internals
|
|---|
