VB produced IE-- own browser Author: Money can Building
Do you do your browser? Have you made a mistake? Don't say like IE like IE, it is a small Opera, and most ordinary people don't do it. But if you have a VB5.0 professional version in your machine, then things will be better, do you want to try it? Well, the protagonist of the Let's Go! Program is an ActiveX control: WebBrowser. Of course, in the default state, there is nothing in the toolbox of VB. We have to manually join, the method is: Right-click the toolbox, select "Parts ..." in the shortcut menu, make sure to select in the pop-up dialog box "Control" tab, find Microsoft Internet Controls, hook in the small box in front, then determine. At this point, you will find that there are more than two small icons in the toolbox, of which the controls of the Earth icon are exactly the WebBrowser we need. Since many people are not very familiar with the WebBrowser control, VB's help has not been related to it (anyway I have not found), so it is necessary to introduce its properties, methods, and events, limited to space, we only involve it in the program. : Property: LocationURL Returns the control to the URL of the web page. Method: NaviGate Transfer to the specified URL or open the specified HTML file. Event: 1. Downloadbegin Downloads Time Time Time Time. 2. DownloadComplete downloads to trigger when done, terminate or fail. 3. The ProgressChange WebBrowser control tracks the process of downloading and triggers this event regularly. Its syntax is: SUB WebBrowser_ProgressChange (Byval ProgressMax as long). Progress variable yuan is the total amount of data that has been downloaded, and ProgressMax is the total amount of data to be downloaded. 4. Titlechange Current Document Title When the title is triggered except for WebBrowser controls, the program also needs a label control: Label1; a ComboBox control: Combo1, used to display the URL address; a StatusBar control: statusbar1; a progressbar control: Progressbar1, used to display the download progress (STATUSBAR controls and ProgressBar controls are members of the ActiveX Control Microsoft Windows Common Controls5.0, the method of adding the toolbox with the WebBrowser control, with the attribute value of these controls with default.
