VC++2012为什么我用CREATEWINDOW创建的EDIT控件只能输入数字，其它都不可以

《Windows程序设计》这本书很好，C+API+VCRC文件由VC维护，我们只需要在VC界面插入资源，某些特殊情况下，也可以自己用记事本打开RC文件进行修改。1.创建主窗口,myclassname是自己用WNDCLASS注册的类名//参数依次是:类名-窗口标题-窗口样式-x-y-width-height-父窗口-菜单ID-实例句柄-CREATESTURCT指针hwnd=CreateWindow(TEXT("myclassname"),TEXT("未命名"),WS_OVERLAPPEDWINDOW,CW_USEDEFAULT,CW_USEDEFAULT,CW_USEDEFAULT,CW_USEDEFAULT,NULL,NULL,hInstance,NULL);2.创建子窗口：必须有WS_CHILD样式，必须指定父窗口//editstaticbuttonlistbox是系统预先定义好的类名//对button指定不同的样式，可有单选按钮、多选按钮、复选框等等形式//对static指定不同的样式，可显示矩形区域、静态文字、加载图标、位图等CreateWindow(TEXT("edit"),TEXT("ES_LEFT"),WS_CHILD|WS_VISIBLE|WS_VSCROLL|ES_MULTILINE|ES_LEFT,0,0,cxChar*20,2*cyChar,hwnd,(HMENU)12,hInst,NULL);CreateWindow(TEXT("button"),TEXT("GROUPBOX"),WS_CHILD|WS_VISIBLE|BS_GROUPBOX,0,3*cyChar,60,4*cyChar,hwnd,(HMENU)0,hInst,NULL);CreateWindow(TEXT("button"),TEXT("RADIOBUTTON"),WS_CHILD|WS_VISIBLE|BS_RADIOBUTTON,0,8*cyChar,60,cyChar,hwnd,(HMENU)1,hInst,NULL);CreateWindow(TEXT("button"),TEXT("AUTORADIOBUTTON"),WS_CHILD|WS_VISIBLE|BS_AUTORADIOBUTTON,0,10*cyChar,60,cyChar,hwnd,(HMENU)2,hInst,NULL);CreateWindow(TEXT("button"),TEXT("AUTOCHECKBOX"),WS_CHILD|WS_VISIBLE|BS_AUTOCHECKBOX,0,12*cyChar,12*cxChar,cyChar,hwnd,(HMENU)3,hInst,NULL);CreateWindow(TEXT("button"),TEXT("CHECKBOX"),WS_CHILD|WS_VISIBLE|BS_CHECKBOX,0,14*cyChar,12*cxChar,cyChar,hwnd,(HMENU)4,hInst,NULL);CreateWindow(TEXT("button"),TEXT("3STATE"),WS_CHILD|WS_VISIBLE|BS_3STATE,0,16*cyChar,12*cxChar,cyChar,hwnd,(HMENU)5,hInst,NULL);CreateWindow(TEXT("button"),TEXT("AUTO3STATE"),WS_CHILD|WS_VISIBLE|BS_AUTO3STATE,0,18*cyChar,12*cxChar,cyChar,hwnd,(HMENU)6,hInst,NULL);CreateWindow(TEXT("button"),TEXT("PUSHBUTTON"),WS_CHILD|WS_VISIBLE|BS_PUSHBUTTON,0,20*cyChar,12*cxChar,cyChar,hwnd,(HMENU)7,hInst,NULL);CreateWindow(TEXT("button"),TEXT("DEFPUSHBUTTON"),WS_CHILD|WS_VISIBLE|BS_DEFPUSHBUTTON,0,22*cyChar,12*cxChar,cyChar,hwnd,(HMENU)8,hInst,NULL);CreateWindow(TEXT("static"),TEXT("SS_LEFT"),WS_CHILD|WS_VISIBLE|ES_AUTOHSCROLL|SS_LEFT,0,24*cyChar,12*cxChar,cyChar,hwnd,(HMENU)9,hInst,NULL);CreateWindow(TEXT("static"),TEXT("SS_BLACKRECT"),WS_CHILD|WS_VISIBLE|ES_AUTOHSCROLL|SS_BLACKRECT,0,26*cyChar,12*cxChar,cyChar,hwnd,(HMENU)10,hInst,NULL);CreateWindow(TEXT("static"),TEXT("SS_BLACKFRAME"),WS_CHILD|WS_VISIBLE|ES_AUTOHSCROLL|SS_BLACKFRAME,0,28*cyChar,12*cxChar,cyChar,hwnd,(HMENU)11,hInst,NULL);

设置了属性only num，去掉数字属性就可以了
