Introduction to toolbar development of IE Toolbar plug-in

Http://www.codeproject.com/KB/shell/ietoolbartutorial.aspx
This tutorial assumes that you already know how to program in C ++ and know
Some information about ATL and COM. To work through this tutorial, you will need
The following installed on your development machine:
1. Visual C ++ 6 installed

2. rbdeskband ATL object wizard (Version
2.0): http://www.codeproject.com/KB/atl/rbdeskband.aspx
3. csf-wimpl ATL
Object Wizard: http://www.codeproject.com/KB/atl/rbcwindowimpl.aspx

Reference: articles that teach you how to develop IE Plug-In toolbar for free are rare. Fortunately, I found an article in codeproject. However, it took a day to write a Google
Search toolbar.

If you download the Internet Explorer Toolbar (bandwidth band)
The source code of tutorial cannot be compiled, so it is not surprising that I am stuck in these places. Let's talk about the compilation problems.

1. compilation problems
　

If you encounter the following problems, the version of commctrl. H is low. We can use tbstyle_ex_mixedbuttons instead.
Tbstyle_ex_drawddarrows. Delete the other three items and change them to tbstyle_button | tbstyle_autosize. This problem is solved.

Error c2065: 'tbstyle _ ex_mixedbuttons ': Undeclared identifier
Error
C2065: 'btns _ click': Undeclared identifier
Error c2065: 'btns _ autosize ':
Undeclared identifier
Error c2065: 'btns _ showtext': Undeclared identifier

If you encounter the following problems, delete the/D _ atl_min_crt in the project file (DSP.

If you re-compile a new project to Implement IE
If toolbar is used, pay attention to the following two points.

1. Pay attention to the Message ing sequence of cmftoolbar. Chain_msg_map_member must be in front of wm_create.

Begin_msg_map (ctoolbarwnd)
Chain_msg_map_member (m_editwnd)

Message_handler (wm_create, oncreate)
...
End_msg_map ()

2. Pay attention to the Message ing sequence of creflectionwnd. Wm_create must be prior to chain_msg_map_member.

Begin_msg_map (creflectwnd)
Message_handler (wm_create, oncreate)

Chain_msg_map_member (m_toolbarwnd)
End_msg_map ()
3. Google Search
Toolbar

Codeproject has very detailed development steps, which will not be repeated here. The purpose of this section is to implement
Search function. Create a colimasbar project and a ccolimasbar class. The IE plugin interface is as follows:

Public
Ccomobjectrootex <ccomsinglethreadmodel>,
Public
Ccomcoclass <ccolimasbar, & clsid_colimasbar>,
Public ideskband,

Public iinputobject,
Public iobjectwithsite,
Public
Idispatchimpl <icolimasbar, & iid_icolimasbar, & libid_iebaselib>

Create ceditwnd class, input bar control, inherit

Public cwindowimpl <ceditwnd>

Create the creflectwnd class, transfer the message space, and inherit

Public cwindowimpl <ceditwnd>

Create ctoolbarwnd class, Toolbar Control, inherit

Public cwindowimpl <ceditwnd>

Modify the title of a toolbar:

Const wchar title_ccolimasbar [] = l "google ";

Modify the title of a button:

Tchar * pcaption = _ T ("search! ");

Added the Google search processing function getvalue for the button click event.

Void
Ctoolbarwnd: getvalue ()
{
// If we have a web browser pointer then try
To navigate to Google site to retrieve search
If (m_pbrowser)
{

Variant vempty;
Variantinit (& vempty );

M_pbrowser-> stop ();
_ Bstr_t bssite;
// If the user has
Entered URL then append them to the Edit
If
(M_editwnd.getwindowtextlength ())
{
Wchar * BSTR = NULL;

M_editwnd.getwindowtext (& BSTR );

Uint I =
Widechartomultibyte (cp_utf8, 0, BSTR,-1, null, 0, null, null); // double-byte Conversion
Char
* Strb = new char [I];
Widechartomultibyte
(Cp_utf8, 0, BSTR,-1, strb, I, null, null); // convert to ASCII
Uint Len = I;
Char *
TMP = new char [Len * 3];
TMP [0] = '/0 ';

For (I = 0; I <len-1; I ++)

{
Byte J = (unsigned char) strb [I]; sprintf (TMP, "% S % x", TMP, J );
// Convert to hexadecimal.

}

Bssite =
L "http://www.google.com/search? Hl = ZH-CN & Q = ";
// Google search string

Bssite + = TMP;
Bssite + =
"& RLS = com. Microsoft: En-US & Ie = utf8 & OE = utf8 ";

Sysfreestring (BSTR );
Delete [] strb;
}
Else

Bssite = "http://www.google.com /";
// Have the webrowser navigate
To the site URL requested depending on user input.

M_pbrowser-> navigate (bssite, & vempty,
& Vempty );
}
}
