CURRENT WORK ITEM - PREVIEW ONLY
The MSHTML option setting MiscFlags sets a few aspects of behaviour, mostly for when MSHTML provides HTML editing services.
| Key | HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Settings |
| Value | MiscFlags |
| Type | REG_BINARY (4 bytes) or REG_DWORD |
| Default | zero (as dword) |
The key shown in the table is only where MSHTML looks for the value ordinarily. If the document host specifies an option key (through the GetOptionKeyPath method of the IDocHostUIHandler interface), then the value is sought instead from the Settings subkey of the option key. If the document host specifies an override key (through the GetOverrideKeyPath method of the IDocHostUIHandler2 interface), then if the value is given in the Settings subkey of the override key, it has precedence.
The value is read either as a dword or as 4 bytes of binary data, and is interpreted as bit flags:
| 0x01 | do not show aligned site tags |
| 0x02 | do not show script tags |
| 0x04 | do not show comment tags |
| 0x08 | do not show style tags |
| 0x10 | do not show area tags |
| 0x20 | do not show unknown tags |
| 0x40 | do not show miscellaneous tags |
| 0x80 | do not show zero border at design time |
| 0x0100 | do not activate normal OLE controls |
| 0x0200 | do not activate design-time controls |
| 0x0400 | do not activate Java applets |
| 0x0800 | do not show BR tags |
The 0x01, 0x04, 0x08, 0x10, 0x20, 0x40 and 0x0800 flags assume an editing context. If any is set before MSHTML has yet prepared an editing context for the document, then a coding error causes MSHTML to dereference a null pointer. These flags look like they may be unusable.
