SUMMARY
=======
This article describes how to print the contents of an HTML document if the HTML
control is embedded in a Visual Basic application by using the WebBrowser
control.
Requirements
------------
The following items describe the recommended hardware, software, network
infrastructure, skills and knowledge, and service packs that you will need.
- Internet Explorer 4.0 or later
- A working knowledge of Visual Basic 6.0 application development for Windows
Embedding a WebBrowser Control in a Visual Basic Form
-----------------------------------------------------
1. Start the Visual Basic 6.0 development environment, and then create a new
Standard EXE project.
2. On the Project menu, click Components. Select the Microsoft Internet Controls
check box, and then click OK to add it to the toolbox.
3. Use the new icon in the toolbox to create a control named WebBrowser1 on
Form1.
4. On the View menu, click Code.
5. Add the following code to the form to load an URL into the browser when the
program starts. The actual URL is not significant in this example; replace it
with any valid URL that you want to use:
Private Sub Form_Load()
WebBrowser1.Navigate2 "http://www.microsoft.com"
End Sub
6. Run the project. The WebBrowser control appears in the form and displays the
Web page that you specified as the first parameter for the Navigate2 method.
Printing from the WebBrowser Control
------------------------------------
1. Add a command button named Command1 to the form.
2. Double-click Command1 to add a click event handler. Edit the code as follows:
Private Sub Command1_Click()
WebBrowser1.ExecWB OLECMDID_PRINT, _
OLECMDEXECOPT_PROMPTUSER, _
0, 0
End Sub
3. Run the project. After the Web page has been loaded, click Command1. A dialog
box appears with printer options. Click the appropriate printer, and then
click OK. The document in the WebBrowser control is printed.
4. If you do not want the dialog box to appear, change the second parameter of
the ExecWB call to OLECMDEXECOPT_DONTPROMPTUSER. This causes the document to
be sent to the printer without further user intervention. However, printing
without prompting the user is not supported on Internet Explorer 5 (see the
"Troubleshooting" section in this article).
Troubleshooting
---------------
If you use the OLECMDEXECOPT_PROMPTUSER option, it is not possible to determine
whether the user clicked OK to print the document or Cancel to cancel printing.
Internet Explorer 4.0 supports both OLECMDEXECOPT_PROMPTUSER and
OLECMDEXECOPT_DONTPROMPTUSER. However, OLECMDID_DONTPROMPTUSER is ignored in
Internet Explorer 5, because printing is considered to be a security issue; a
Web page should not have the ability to start a print job without confirmation
from the user. In Internet Explorer 5.5 and later, the print job is completed
without user confirmation.
