void PropertyChange(
BSTR szProperty,
);
Notifies an application that the PutProperty method has changed the value of a property.
See also IWebBrowser2::GetProperty, IWebBrowser2::PutProperty
void StatusTextChange(
[in] BSTR bstrText
);
Notifies an application that the text of the status bar associated with the WebBrowser control has changed.
void TitleChange(
[in] BSTR Text
);
Notifies an application if the title of a document in the WebBrowser control becomes available or changes.
Because the title might change while an HTML page is downloading, the URL of the document is set as the title. After the title specified in the HTML page, if there is one, is parsed, the title is changed to reflect the actual title.

This section defines enumerations used with the WebBrowser interfaces.
typedef enum BrowserNavConstants {
navOpenInNewWindow = 0x1,
navNoHistory = 0x2,
navNoReadFromCache = 0x4,
navNoWriteToCache = 0x8
navAllowAutosearch = 0x10,
navBrowserBar = 0x20
} BrowserNavConstants;
Contains values used by the IWebBrowser2::Navigate and IWebBrowser2::Navigate2 methods.
Values
| navOpenInNewWindow | Open the resource or file in a new window. |
| navNoHistory | Do not add the resource or file to the history list. The new page replaces the current page in the list. |
| navNoReadFromCache | Not used. |
| navNoWriteToCache | Not used. |
| navAllowAutosearch | If the navigation fails, the autosearch functionality will attempt to navigate common root domains (.com, .edu, and so on). If this still fails, the URL will be passed to a search engine. |
| navBrowserBar | Causes the current Explorer Bar to navigate to the given item, if possible. |

typedef enum CommandStateChangeConstants {
CSC_UPDATECOMMANDS = 0xFFFFFFFF,
CSC_NAVIGATEFORWARD = 0x00000001,
CSC_NAVIGATEBACK = 0x00000002
} CommandStateChangeConstants;
Contains values used by the DWebBrowserEvents2::CommandStateChange event.
Values
| CSC_UPDATECOMMANDS | The enabled state of a toolbar button might have changed. |
| CSC_NAVIGATEFORWARD | The enabled state of the Forward button has changed. |
| CSC_NAVIGATEBACK | The enabled state of the Back button has changed. |
typedef enum tagREADYSTATE{
READYSTATE_UNINITIALIZED = 0,
READYSTATE_LOADING = 1,
READYSTATE_LOADED = 2,
READYSTATE_INTERACTIVE = 3,
READYSTATE_COMPLETE = 4
} READYSTATE;
Contains values that indicate what state an object is in. This is used with the ReadyState property and the IWebBrowser2::get_ReadyState method.
Values
| READYSTATE_UNINITIALIZED | The default initialization state. |
| READYSTATE_LOADING | The object is currently loading its properties. |
| READYSTATE_LOADED | The object has been initialized. |
| READYSTATE_INTERACTIVE | The object is interactive, but not all of its data is available. |
| READYSTATE_COMPLETE | The object has received all of its data. |
typedef enum RefreshConstants {
REFRESH_NORMAL = 0,
REFRESH_IFEXPIRED = 1,
REFRESH_CONTINUE = 2,
REFRESH_COMPLETELY = 3
} RefreshConstants;
Contains values used with the Refresh2 and IWebBrowser2::Refresh2 methods.
The "pragma:nocache" header tells the server not to return a cached copy but to ensure that the information is as fresh as possible. Browsers typically send this header when the user selects Refresh, but the header can cause problems for some servers.
Values
| REFRESH_NORMAL | Perform a lightweight refresh that does not include sending the HTTP "pragma:nocache" header to the server. |
| REFRESH_IFEXPIRED | Perform a lightweight refresh if the page has expired. |
| REFRESH_CONTINUE | For internal use only; do not use. |
| REFRESH_COMPLETELY | Perform a full refresh that includes sending a "pragma:nocache" header to the server (HTTP URLs only). |
