Registration: regsvr32 shdocvw. dll
WebBrowser is a VB Control made by the IE kernel,
WebBrowser. Document is the automatic Object returned for the active Document. You can reference Microsoft HTML Object Library to view detailed attributes and methods.

The following illustration assumes that there is a WebBrowser control named Web1 in the form.
■ Method ==================================
▲Goback is equivalent to IE's "back" button, so that you can return
▲Goforward is equivalent to IE's "Forward" button, which enables you to move forward an item in the Current History List
▲Gohome is equivalent to the "Homepage" button of IE and connects to the user's default homepage.
▲Gosearch is equivalent to IE's "Search" button and connects to the user's default search page
▲Navigate connects to the specified URL and displays the webpage
▲Does Navigate2 play the same role as Navigate?
▲Refresh Refresh the current page
▲Refresh2 is the same as above, but the refresh level can be specified. The value of the specified refresh level comes from the RefreshConstants enumeration table,
This table is defined in ExDisp. h. Different values can be specified as follows:
REFRESH_NORMAL: Do not send HTTP pragma: no-cache hair to the server
REFRESH_IFEXPIRED can be refreshed only after the webpage expires.
REFRESH_CONTINUE is only used internally. Do not use in MSDN! Do not use
REFRESH_COMPLETELY sends requests containing the pragma: no-cache header to the server
▲Stop is equivalent to the "Stop" button of IE to Stop loading of the current page and its content.
■ Attributes ======================================================
▲Document is the automatic object returned for the active Document. If HTML is currently being displayed in Web1, the Document provides
The access path to the DHTML Object Model. The following is a detailed introduction.
▲Toplevelcontainer returns a Boolean value indicating whether IE is the top-level container of the Web1 control. true is returned if it is true.
▲Type: return the Type of the object loaded by the Web1 control. For example:
If the .doc file is used, Microsoft Word Document is returned.
▲Locationname returns a string containing the name of the currently displayed resource in Web1,
If the resource is a webpage, It is the title of the webpage;
If it is a file or folder, It is the name of the file or folder.
▲Locationurl: the URL of the resource currently being displayed in Web1 is returned.
▲Busy returns a Boolean value, indicating whether Web1 is currently loading the URL. If true is returned
You can use the stop method to cancel the ongoing access operation.
▲If the Object is set, a SHDocVwCtl. WebBrowser_V1 Object indicating the webpage is returned. See the following.
▲Menubar
▲Statusbar
▲Toolbar
▲Visible
▲
■ Event ============================================
▲Beforenavigate2: triggered before the navigation occurs (before the webpage is opened), not triggered during refresh
▲Commandstatechange is triggered when the command activation status changes. It indicates when to activate or disable the Back and Forward menu items or buttons.
▲Documentcomplete: when the entire document is completed, it is not triggered when the page is refreshed.
▲Downloadbegin: this event is triggered when a download operation has started and refreshed.
▲Downloadcomplete triggered when a download operation is completed, refresh can also trigger this event
▲Triggered after NavigateComplete2 is complete and not triggered during refresh
▲Newwindow2 triggered before a new window pops up
You can set the ppDisp parameter in this event to display the object on the new webpage without the NewWindow event of SHDocVwCtl. WebBrowser_V1.
▲Onfullscreen is triggered when the FullScreen attribute changes. This event uses an input parameter of VARIENT_BOOL to indicate that IE is full.
Display Mode (VARIENT_TRUE) or normal display mode (VARIENT_FALSE)
▲Onmenubar is triggered when the MenuBar attribute is changed. It indicates that the parameter is of the VARIENT_BOOL type.
VARIANT_TRUE visible, VARIANT _ FALSE hidden
▲Onquit: whether the user closes the browser or the developer calls the Quit method, it will trigger when IE exits.
▲Onstatusbar is triggered when the StatusBar attribute is changed, indicating whether the status bar is visible.
▲Ontoolbar is triggered when the ToolBar attribute is changed to indicate whether the ToolBar is visible.
▲Triggered when OnVisible attribute is changed
▲Triggered when the status information of the StatusTextChange control changes.
▲Titlechange is triggered when the webpage title changes. The Text parameter is the new title, and the Web1.LocationName attribute is the old title.
■ SHDocVwCtl. WebBrowser_V1 object ======================
Add Private WithEvents Web_V1 As SHDocVwCtl. WebBrowser_V1 to the form declaration section.
Add: Set Web_V1 = Web1.Object to Form_Load.
In this way, Web_V1 will have the following events:
▲Newwindow is triggered before a new window is displayed.
If ppDisp is set as a New Display object in webdesknewwindow2, this event will not occur.
★Example 1: a pop-up page is displayed in the new window of the self-developed program:
Dim nForm As New formmain' FormMain is your form with the Web1 Control
Processed = true' to prevent the control from calling the IE pop-up window
NForm. Show
NForm. Web1.Navigate URL
★Example 2: display the webpage in the same window:
Processed = true' to prevent the control from calling the IE pop-up window
Web1.Navigate URL
■
■ Web1.Document object (HTMLDocument object) ======================
▲All (1) set, All tag objects included in the html document loaded to Web1: HTMLAreaElement
The index start point of the Set object is 0, and the total number is All. length.
You can use indexes to access objects, such as All (1)
You can also use the Html Header element name to access the object, for example, All ("body ")
All (0) is generally its own outerHTML. You can return the document code (view the source file) as follows ):
Text1.Text = Web1.Document. All (0). outerhtml
However, the previous statement is not reliable. Some codes starting with a Web page are not The All () set has most attributes of the HTMLAreaElement object, and some elements have special attributes.
Note that the sourceIndex attribute of an element is the number of the object in the Document. All () set.
