Creating Internet Program in VC++ :-
Including a web browser in VC++. Creating your own web browser in VC++ is easy, because the Microsoft internet explorer which is the foundation application of the info-viewer in VC++ can be used as a control in our program.
To display the Microsoft home page in our web browser we need to add a new Microsoft web browser control to our program, creating a member object for it & we use its navigate() method.
To display the Microsoft home page in our web browser we need to add a new Microsoft web browser control to our program, creating a member object for it & we use its navigate() method.
Steps are :->
- Create a new dialog-based program called "browser".
- Select Project -> Add Project -> Components and control. This opens the VC++ components and control gallery.
- Now double click the entry marked registered ActiveX controls to open the list of ActiveX controls in your system.
- Select the Microsoft web browser control and then click on Insert button.
- VC++ asks you what class you want for this new control, accept the default suggestion! CwebBrowser. This adds the web browser control to the dialog editors toolbox.
- Open the main dialog window in dialog editor.
- Drag the browser control which appears at the bottom in the toolbox to the dialog window under design. This gives the browser control the ID : IDC-EXPLORER.
- Using class wizard, connect a member variable to the browser control, naming that variable m-browser.
- Add a button with caption Browse: to the dialog window and connect an event handler method OnButton1() to that button.
- When the user clicks the Browse button we can navigate our web browser to www.microsoft.com. For this, we use the web browser control method Navigate() ( in which, the last four parameters are flags that we set to 0 ).
Void CBrowser Dlg : : OnButton1()
{
m_browser.Navigate ( " http:\\ www.microsoft.com ",0,0,0,0 )
}
Run the program.
