MFC patchwork SQL statement methods
Sql_insert. Format (_t ("INSERT into UserInfo (name) values (\ '%s\ ');"), name);
std::string s= CStringA (Sql_insert);
const char *ch = S.C_STR ();

MFC gets other page control methods
cmcfstudentdlg* pWnd = (cmcfstudentdlg*) GetParent ();
CListCtrl *plist= (CListCtrl *) Pwnd->getdlgitem (IDC_LIST1);
UpdateData (TRUE);

Traverse Map
Map<cstring,sockaddr_in>::iterator it;
it = Person.begin ();
while (It! = Person.end ())
{
it + +;
M_combo. AddString (It->first);
}

Split string
int main (void)
{
Char str[] = "2015-3-22,abcd,efg,hij,klmn,opq,rst,uvw,xyz,tao";/* The original string to be delimited */
Char seg[] = ","; /* Delimiter here is a comma comma, delimiter can be specified for you, such as semicolon, space, etc. */

constructor function:
The function name is the same as the class name, and the constructor is used to initialize the parameters directly by default when calling the class, even if the constructor is not written, the system will default to you a constructor (there are virtual members in the class, there are constructors for the base class in the class, static members have constructors)

When constructing a class, if the passed in parameter is the same as the parameter name of the argument in the class, the parameter in the specified class is used This->x

C + + can accept multiple inheritance
Class A:public B,public c{}

Virtual functions
virtual void Breath ()
{ }
C + + at compile time does not bind breath, will be called at the time of the specific call that method, if not declared, will be at compile time binding method. Add virtual to C + + to implement polymorphism, add virtual to the base class method, override the function in the derived class, and the runtime will invoke the appropriate method based on the actual type of the object.

Pure virtual function
virtual void Breathe () =0
The method is not implemented, just a declaration. When a derived class inherits, it is necessary to implement a pure virtual function, otherwise the derived class can only be used as an abstract class and cannot be instantiated

Overwrite and hide
Overwrite: function name is same, parameter is same, function is virtual function. When you create an instance object, you bind the virtual function to a function in the Power class
Hidden: A function is not a virtual function and is hidden as long as the function name is the same or the parameter is the same. To implement a hidden function base class name in a derived class:: Function name (parameter)
Overloads of a function occur in the same class.

int a=3;
int &b=a;
int c=5;
B=c;
At this point A and B values are 5, and A's value represents the value of B.
int a=3;
int *b=&a;
At this point B is the storage address of a, that is, the pointer, and then change the value of B is to change the value of the pointer, a value will not change.

Resolve header file Duplicate definition
Add the following statement in the Animal.h
#ifndef Animal_h_h
#define Animal_h_h

static sockaddr_in addrsrv = Person[strcbtext];

HWND hwnd = (HWND) FindWindow (NULL, window name);//Get window handle based on window name caption
c***dialog* pwnd= (c***dialog*) c***dialog::fromhandle (hWnd); Object pointer to get dialog box by handle
Pwnd->xxx (); Call C***dialog in the function xxx ();
HWND hwnd = Pwnd->getsafehwnd (); Gets the handle to the control

Edit Control
Get pointer
Pboxone = (cedit*) GetDlgItem (IDC_EDIT1);
Assign value
Pboxone-> SetWindowText (_t ("FOO"));
Take value
pboxone-> GetWindowText (str);

C + + global variables
The. h file adds
extern CString Tomessage;
The. cpp file adds
CString Strcbtext;
Other file references under the same item are added
. h files and extern CString strcbtext; declaring variables

Gets the value of the popup box selected
function sub () {
var s = ';
var obj = document.getelementsbyname (' User ');
for (var i = 0; i < obj.length; i++) {
if (obj[i].checked)

}
var Name = $ ("#" + s). Parent (). Next (). text ();
var Phone = $ ("#" + s). Parent (). Next (). Next (). text ();
document.getElementById ("TUser"). Value = Name;
}

JS Gets the selected value of the Select tag
var obj = document.getelementbyidx_x ("Testselect"); Location ID
var index = Obj.selectedindex; Check Index
var text = Obj.options[index].text; Select text
var value = Obj.options[index].value; Checked values
Get selected Select value in jquery

The first way
$ (' #testSelect option:selected '). text ();//Selected texts
$ (' #testSelect option:selected '). Val ();//Selected value
$ ("#testSelect"). Get (0). selectedindex;//Index

The second way
$ ("#tesetSelect"). Find ("option:selected"). Text ();//Selected
.... val ();
..... get (0). SelectedIndex;

Pop-up box is not useful
Scriptmanager.registerstartupscript (this, this.) GetType (), "", "alert (' Insufficient account balance ');", true);
Hide an element in the background
Scriptmanager.registerstartupscript (this, this.) GetType (), "", "$ (function () {$ (\". qbm-notice\ "). css (\" display\ ", \" None\ ");})", true);

The database does not recognize Chinese characters, and when setting up the connection string, add: Charset=utf8

How to use objects such as ASP. Request,server in your custom class:
namespace (you may need to add a reference to the project before referencing it in the class)
Using System.Web.SessionState;
httpcontext.current.session["Totalpage"]. ToString ();
httpcontext.current.request.querystring["CID"]. ToString ();

Use of Ajax

The interface must refer to Jquery.min.js
<script type= "Text/javascript" >
function Sub () {
$ (document). Click (function (e) {
var name=$ (E.target). Parent (). Prev (). Prev (). Prev (). Prev (). Prev (). Prev (). Prev (). text ();
var p = $ (e.target). attr ("id");
var p = ' U ';
var params = ' {IP: ' ' + P + ' "} ';
var params = ' {name1: ' + name + ', phone1: ' + Phone + ' '} ';
$.ajax ({
Type: "Post",
URL: "Phone.aspx/submit",
Data:params,
ContentType: "Application/json;charset=utf-8",
DataType: "JSON",
Success:function E () {
Shanchu.remove ();
Alert ("Operation succeeded! ");
},
Error:function () {alert ("Llll");}
});
// })
}
</script>

The values returned by the background are split
Success:function e (msg) {
var Name = document.getElementById ("Stuname");
var STRs = Msg.d.split (";"); Character segmentation
for (var i = 0; i < strs.length; i++) {
if (strs[i]! = "") {
name.innerhtml + = ' <li class=\ "Flex bd-lis\" ><section class=\ "Iconfont icon-yuanxingweixuanzhong bd-a\" > </section><section class=\ "bd-b\" ></section><section class=\ "bd-c\" > ' + strs[i].toString () + ' </section><section class=\ ' bd-d iconfont icon-xiangyou1\ ' ></section></li> ';
}
}
},
Error:function () {alert ("Llll");}

Background

[System.Web.Services.WebMethod ()]
public static void Submit (String IP)
{

}

Gets the ID of the current click event element:
$ (". BL"). Click (function (e) {
Window.location.href = "noticedetil.aspx?id=" + $ (This). attr ("ID");
})

Pre-load Modify page

$ (function () {
var detile= ' <%=NoticeDeilStr%> ';
var STRs = Detile.split (";");
$ ("#NoticeType"). Append (Strs[0]);
$ ("#NoticeTitle"). html (strs[1]);
$ ("#StartTime"). html (strs[2]);
$ ("#OverTime"). html (strs[3]);
$ ("#StopTime"). html (strs[4]);
$ ("#NoticeContent"). html (strs[5]);
})

When you need information for more than one table, you don't have to make multiple queries, and you can put the data together using left-right or inner joins.
Select T1.id,t2.id as pp,t1.phone as TT from ((SELECT * from ' user ' where id= ' ee ') t1 the left JOIN (SELECT * from ' user ' wher E Roleid = ' 1 ') t2 on T1.classid=t2.classid)

Pass the Click object:

Onclick= "Sub (This)"

Receive: function Sub (obj) {
var p = $ (obj). Prev (). attr ("id");
}

Ajax button Jump, you can only use the Button property, do not use the submit

Write to Foreground JS

StringBuilder sb = new StringBuilder ();
Sb. Append ("<script src=\" js/jquery-weui.js\ "></script>;");
Clientscript.registerstartupscript (this. GetType (), "Loadpicscript", sb. ToString ());

Apple returns without reloading JS

<input type= "hidden" id= "refreshed" value= "no" >

if ((/iphone|ipod|ipad.*os 5/gi). Test (navigator.appversion)) {

Server control add Foreground JS event

BUTTON1.ATTRIBUTES.ADD ("OnClick", "Return Load ()");
function returns True to continue the background click event
function returns false only the foreground JS event is executed
