VC_Edit_Control_VC中Edit Control控件的⽤法
简介摘要：; } 1.设置edit只读属性⽅法⼀：m_edit1.SetReadOnly(TRUE); ⽅法⼆：::SendMessage(m _edit1.m_hWnd,
EM_SETREADONLY, TRUE, 0); 2.判断edit中光标状态并得到选中内容(richedit同样适⽤)
; }
1.设置[she zhi]edit只读[zhi du]属性[shu xing][zhi du shu xing]
⽅法[fang fa]⼀：m_edit1.SetReadOnly(TRUE);
⽅法[fang fa]⼆：::SendMessage(m_edit1.m_hWnd, EM_SETREADONLY, TRUE, 0);
2.判断edit中光标[guang biao]状态[zhuang tai]并得到选中内容(richedit同样适⽤)
int nStart, nEnd;
CString strTemp;
m_edit1.GetSel(nStart, nEnd);
if(nStart == nEnd)
｛
strTemp.Format(_T(" 光标[guang biao]在%d" ), nStart);
AfxMessageBox(strTemp);
｝
else
｛
//得到edit选中的内容
m_edit1.GetWindowText(strTemp);
strTemp = strTemp.Mid(nStart) - strTemp.Mid(nEnd);
AfxMessageBox(strTemp);
｝
注：GetSel后，如果nStart和nEnd，表明光标[guang biao]处于某个位置[wei zhi]（直观来看就是光标[guang biao]在闪动）；如果nStart和nEnd不相等，表明⽤户[yong hu]在edit中选中了⼀段内容。
3.在edit最后添加字符[zi fu]串[zi fu chuan]
CString str;
m_edit1.SetSel(-1, -1);
m_edit1.ReplaceSel(str);
4.随输⼊[shu ru]⾃动滚动到最后⼀⾏(richedit同样适⽤)
⽅法[fang fa]⼀：（摘⾃msdn）
// The pointer to my edit.
extern CEdit* pmyEdit;
int nFirstVisible = pmyEdit-> GetFirstVisibleLine();
// Scroll the edit control so that the first visible line
// is the first line of text.
if (nFirstVisible > 0)
｛
pmyEdit-> LineScroll(-nFirstVisible, 0);
｝
⽅法[fang fa]⼆：m_richedit.PostMessage(WM_VSCROLL, SB_BOTTOM, 0);
5.如何限制edit输⼊[shu ru]指定字符[zi fu]
可以从CEdit派⽣[pai sheng]⼀个类，添加WM_CHAR消息[xiao xi]映射[ying she]。下⾯⼀个例⼦实现了限定输⼊[shu ru]16进制字符[zi fu]的功能。
void CMyHexEdit::OnChar(UINT nChar, UINT nRepCnt, UINT nFlags)
｛
if ( (nChar > = 0 && nChar < = 9) ||
(nChar > = a & & nChar < = f) ||
(nChar > = A && nChar < = F) ||
nChar == VK_BACK ||
nChar == VK_DELETE) //msdn的virtual key
｛
CEdit::OnChar(nChar, nRepCnt, nFlags);
｝
｝
6.如何使⽤richedit
添加AfxInitRichEdit();
CxxxApp::InitInstance()
｛
AfxInitRichEdit();
.............
｝
AfxInitRichEdit()功能：装载RichEdit 1.0 Control (RICHED32.DLL).
7.如何使⽤richedit2.0 or richedit3.0
使⽤原因：由于RichEdit2.0A⾃动为宽字符[zi fu]（WideChar），所以它可以解决中⽂[zhong wen]乱码以及⼀些汉字问题[wen ti]
⽅法[fang fa]⼀：（msdn上的做法，适⽤于[yong yu]⽤www.doczj/doc/55cda82e453610661ed9f4f5.html 及以后版本创建的⼯程）
To update rich edit controls in existing Visual C++ applications t o version 2.0,
open the .RC file as text, change the class name of each rich e dit control from " RICHEDIT" to " RichEdit20a" .
Then replace the call to AfxInitRichEdit with AfxInitRichEdit2.
⽅法[fang fa]⼆：以对话框[dui hua kuang]为例：
(1) 增加⼀全局变量[bian liang][quan ju bian liang] HMODULE hMod;
(2) 在CxxxApp::InitInstance()中添加⼀句hMod = LoadLibrary(_T(" rich ed20.dll" ));
在CxxxApp::ExitInstance()中添加⼀句FreeLibrary(hMod);
(3) 在对话框[dui hua kuang]上放⼀个richedit，⽂本[wen ben]⽅式打开.rc⽂件[wen jian]修改[xiu gai]该richedit控件的类名" RICHEDIT" to " RichEdit20a" .
(4) 在对话框[dui hua kuang]头⽂件[wen jian]添加CRichEditCtrl m_ richedit;
在OnInitDialog中添加m_richedit.SubclassDlgItem(IDC_RICHEDI T1, this);
8.改变richedit指定区域[qu yu]的颜⾊及字体[zi ti]
CHARFORMAT cf;
ZeroMemory(&cf, sizeof(CHARFORMAT));控件的使用
cf.cbSize = sizeof(CHARFORMAT);
cf.dwMask = CFM_BOLD | CFM_COLOR | CFM_FACE |
CFM_ITALIC | CFM_SIZE | CFM_UND ERLINE;
cf.dwEffects = 0;
cf.yHeight = 12*12; //⽂字[wen zi]⾼度
strcpy(cf.szFaceName ,_T(" ⾪书" )); //设置[she zhi]字体[zi ti]
m_richedit1.SetSel(1, 5); //设置[she zhi]处理区域[qu yu]
m_richedit1.SetSelectionCharFormat(cf);
9.设置[she zhi]⾏间距（只适⽤于[yong yu]richedit2.0）
PARAFORMAT2 pf;
pf2.cbSize = sizeof(PARAFORMAT2);
pf2.dwMask = PFM_LINESPACING | PFM_SPACEAFTER;
pf2.dyLineSpacing = 200;
pf2.bLineSpacingRule = 4;
m_richedit.SetParaFormat(pf2);

20. 在Edit中回车时，会退出[tui chu]对话框[dui hua kuang]
选中Edit的风格Want Return。
MSDN的解释[jie shi]如下：
ES_WANTRETURN Specifies that a carriage return be inserted when the user pres ses the ENTER key while entering text into a multiple-line edit control in a dialog b ox. Without this style, pressing the ENTER key has the same effect as pressing the dialog boxs default pushbutton. This style has no effect on a single-line edit contro l.

如何在RichEdit中实现上标下标
正⽂：
近来有好多朋友问如何在RichEdit中实现上标下标，查了好多资料都没到。今天⽆意间在Delphi区闲逛，看到⼀份实现上下标的⽂章，于是整理成CB语⾔的贴出来。
以下代码已测试通过。在Form中放置⼀个RichEdit，两个Button，完整代码如下：
