1、首先，在ScintillaWnd.h头文件中添加如下代码

HMODULE m_hSciLexerDll;

如下图：

2、在ScintillaWnd.cpp源文件的构造函数和析构函数中添加如下代码

ScintillaWnd::ScintillaWnd(){	m_hSciLexerDll = NULL;	m_hSciLexerDll = LoadLibrary(_T("SciLexer.dll"));	if (NULL == m_hSciLexerDll)	{		AfxMessageBox(_T("LoadLibrary SciLexer.dll failure..."));	}}

这是构造函数

ScintillaWnd::~ScintillaWnd(){	if (NULL != m_hWnd)	{		DestroyWindow();	}	if (m_hSciLexerDll != NULL)	{		FreeLibrary(m_hSciLexerDll);	}}

这是析构函数

3、为窗口类创建Create函数

打开类向导，选择“ScintillaWnd”类，找到“虚函数”，找到“Create”函数，点击“添加函数”。

Create函数

添加完“Create”函数，会自动生成一些代码，这些代码不需要改动，保持原样就好。

4、为窗口类添加Init()函数，先在ScintillaWnd.h中添加下面的代码

virtual void Init();

点击图中“小灯泡”，会提示你在ScintillaWnd.cpp文件中创建Init()函数，点击创建。

在创建的Init()函数中添加如下代码

void ScintillaWnd::Init(){	// clear all text styles	SendMessage(SCI_CLEARDOCUMENTSTYLE, 0, 0);	// set the number of styling bits to 7 - the asp/html views need a lot of styling - default is 5	// If you leave the default you will see twiggle lines instead of ASP code	SendMessage(SCI_SETSTYLEBITS, 7, 0);	// set the display for indetation guides to on - this displays virtical dotted lines from the beginning of	// a code block to the end of the block	SendMessage(SCI_SETINDENTATIONGUIDES, TRUE, 0);	// set tabwidth to 4	SendMessage(SCI_SETTABWIDTH, 4, 0);	// set indention to 4	SendMessage(SCI_SETINDENT, 4, 0);	// set the caret blinking time to 400 milliseconds	SendMessage(SCI_SETCARETPERIOD, 400, 0);	// display fold margins	SetFold();	// hide SelectionMargin	SendMessage(SCI_SETMARGINWIDTHN, 1, 0);	// set markersymbol for marker type 0 - bookmark	SendMessage(SCI_MARKERDEFINE, 0, SC_MARK_CIRCLE);	// set the forground color for some styles	SendMessage(SCI_STYLESETFORE, 0, RGB(0, 0, 0));	SendMessage(SCI_STYLESETFORE, 2, RGB(0, 64, 0));	SendMessage(SCI_STYLESETFORE, 5, RGB(0, 0, 255));	SendMessage(SCI_STYLESETFORE, 6, RGB(200, 20, 0));	SendMessage(SCI_STYLESETFORE, 9, RGB(0, 0, 255));	SendMessage(SCI_STYLESETFORE, 10, RGB(255, 0, 64));	SendMessage(SCI_STYLESETFORE, 11, RGB(0, 0, 0));	// set the backgroundcolor of brace highlights	SendMessage(SCI_STYLESETBACK, STYLE_BRACELIGHT, RGB(0, 255, 0));	// set end of line mode to CRLF	SendMessage(SCI_CONVERTEOLS, 2, 0);	SendMessage(SCI_SETEOLMODE, 2, 0);	// SendMessage(SCI_SETVIEWEOL, TRUE, 0);	//显示当前行的淡黄色背景	SendMessage(SCI_SETCARETLINEVISIBLE, TRUE, 0);	SendMessage(SCI_SETCARETLINEBACK, RGB(255, 255, 0), 0);	SendMessage(SCI_SETCARETLINEBACKALPHA, 100, 0);}

注意：要在ScintillaWnd.h头文件中包含Scintilla.h和SciLexer.h头文件

为窗口类添加InitScintillaEdit函数，在ScintillaWnd.h中添加下面的代码

void InitScintillaEdit(int nSize, const TCHAR* face);

用同样的方法，在ScintillaWnd.cpp文件中创建InitScintillaEdit函数

在创建的InitScintillaEdit函数添加如下代码

void ScintillaWnd::InitScintillaEdit(int nSize, const TCHAR * face){	setCppSyntax();	Init();	SetDefaultColorFont(nSize, face);	UpdateLineNumberWidth();}

为窗口类添加SetDefaultColorFont函数

void SetDefaultColorFont(int nSize, const TCHAR* face);

在创建的SetDefaultColorFont函数添加如下代码

void ScintillaWnd::SetDefaultColorFont(int nSize, const TCHAR * face){	SendMessage(SCI_SETSELFORE, TRUE, RGB(255, 255, 255));	//选中行的颜色	SendMessage(SCI_SETSELBACK, TRUE, RGB(10, 36, 106));	//默认文本颜色	SendMessage(SCI_STYLESETFORE, STYLE_DEFAULT, RGB(0x00, 0x00, 0x00));	SendMessage(SCI_STYLESETBACK, STYLE_DEFAULT, RGB(0xff, 0xff, 0xff));	SendMessage(SCI_STYLESETSIZE, STYLE_DEFAULT, nSize);	SendMessage(SCI_STYLESETFONT, STYLE_DEFAULT, reinterpret_cast<LPARAM>(face));}

为窗口类添加SetFold函数

void SetFold(BOOL bFold = TRUE);

在创建的SetFold函数添加如下代码

void ScintillaWnd::SetFold(BOOL bFold){	if (bFold)	{		// source folding section		// tell the lexer that we want folding information - the lexer supplies "folding levels"		SendMessage(SCI_SETPROPERTY, (WPARAM) "fold", (LPARAM)"1");		SendMessage(SCI_SETPROPERTY, (WPARAM) "fold.html", (LPARAM)"1");		SendMessage(SCI_SETPROPERTY, (WPARAM) "fold.html.preprocessor", (LPARAM)"1");		SendMessage(SCI_SETPROPERTY, (WPARAM) "fold.comment", (LPARAM)"1");		SendMessage(SCI_SETPROPERTY, (WPARAM) "fold.at.else", (LPARAM)"1");		SendMessage(SCI_SETPROPERTY, (WPARAM) "fold.flags", (LPARAM)"1");		SendMessage(SCI_SETPROPERTY, (WPARAM) "fold.preprocessor", (LPARAM)"1");		SendMessage(SCI_SETPROPERTY, (WPARAM) "styling.within.preprocessor", (LPARAM)"1");		SetMarginWidthN(2, 16); //SendMessage( SCI_SETMARGINWIDTHN, 2, 16 ); // FoldMargin		SendMessage(SCI_SETMARGINTYPEN, 2, SC_MARGIN_SYMBOL);//页边类型		SendMessage(SCI_SETMARGINMASKN, 2, SC_MASK_FOLDERS); //页边掩码		SendMessage(SCI_SETMARGINWIDTHN, 2, 16); //页边宽度		SendMessage(SCI_SETMARGINSENSITIVEN, 2, TRUE); //响应鼠标消息		// 折叠标签样式		SendMessage(SCI_MARKERDEFINE, SC_MARKNUM_FOLDER, SC_MARK_CIRCLEPLUS);		SendMessage(SCI_MARKERDEFINE, SC_MARKNUM_FOLDEROPEN, SC_MARK_CIRCLEMINUS);		SendMessage(SCI_MARKERDEFINE, SC_MARKNUM_FOLDEREND, SC_MARK_CIRCLEPLUSCONNECTED);		SendMessage(SCI_MARKERDEFINE, SC_MARKNUM_FOLDEROPENMID, SC_MARK_CIRCLEMINUSCONNECTED);		SendMessage(SCI_MARKERDEFINE, SC_MARKNUM_FOLDERMIDTAIL, SC_MARK_TCORNERCURVE);		SendMessage(SCI_MARKERDEFINE, SC_MARKNUM_FOLDERSUB, SC_MARK_VLINE);		SendMessage(SCI_MARKERDEFINE, SC_MARKNUM_FOLDERTAIL, SC_MARK_LCORNERCURVE);		// 折叠标签线颜色		SendMessage(SCI_MARKERSETBACK, SC_MARKNUM_FOLDERSUB, 0xff0000); //蓝色		SendMessage(SCI_MARKERSETBACK, SC_MARKNUM_FOLDERMIDTAIL, 0xff0000);		SendMessage(SCI_MARKERSETBACK, SC_MARKNUM_FOLDERTAIL, 0xff0000);		SendMessage(SCI_SETFOLDFLAGS, 16 | 4, 0); //如果折叠就在折叠行的上下各画一条横线	}	else	{		SetMarginWidthN(2, 0); //SendMessage( SCI_SETMARGINWIDTHN, 2, 0 ); // FoldMargin	}}

为窗口类添加ToggleFold函数

void ToggleFold(long line);

在创建的SetFold函数添加如下代码

void ScintillaWnd::ToggleFold(long line){	SendMessage(SCI_TOGGLEFOLD, static_cast<WPARAM>(line), 0);}

为窗口类添加GetMarginWidthN函数

int GetMarginWidthN(int margin);

在创建的GetMarginWidthN函数添加如下代码

int ScintillaWnd::GetMarginWidthN(int margin){	return SendMessage(SCI_GETMARGINWIDTHN, static_cast<WPARAM>(margin), 0);}

为窗口类添加SetMarginWidthN函数

void SetMarginWidthN(int margin, int mask);

在创建的SetMarginWidthN函数添加如下代码

void ScintillaWnd::SetMarginWidthN(int margin, int mask){	SendMessage(SCI_SETMARGINWIDTHN, static_cast<WPARAM>(margin), static_cast<LPARAM>(mask));}

为窗口类添加UpdateLineNumberWidth函数

void UpdateLineNumberWidth(void);

在创建的UpdateLineNumberWidth函数添加如下代码

void ScintillaWnd::UpdateLineNumberWidth(void){	//start 显示行号	long iLineMarginWidthNow;	long iLineMarginWidthFit;	long iLineNum = SendMessage(SCI_GETLINECOUNT, 0, 0);	long iLineNumCount = 1;	while (iLineNum != 0)	{		++iLineNumCount;		iLineNum /= 10;	}	iLineMarginWidthNow = SendMessage(SCI_GETMARGINWIDTHN, 0, 0);	long charWidth = SendMessage(SCI_TEXTWIDTH, STYLE_LINENUMBER, (LPARAM)("9"));	iLineMarginWidthFit = charWidth * iLineNumCount;	if (iLineMarginWidthNow != iLineMarginWidthFit)	{		SendMessage(SCI_SETMARGINWIDTHN, 0, iLineMarginWidthFit);	}	//end of 显示行号}

为窗口类添加LineFromPosition函数

long LineFromPosition(long pos);

在创建的LineFromPosition函数添加如下代码

long ScintillaWnd::LineFromPosition(long pos){	return SendMessage(SCI_LINEFROMPOSITION, static_cast<WPARAM>(pos), 0);}

ScintillaWnd窗口类的大部分代码已经添加完成，后续还要添加一些代码，下一章会讲在CCppEditorDlg类中添加代码，给CCppEditorDlg类添加完代码后，项目就可以编译运行了，但这只是一个简单的版本，我还会添加功能，到时候再为大家讲解。
