假设我有一个网站,主页上不需要网络套接字,但是在某些其他相对路径(例如'/ new')上需要它.
假设我需要"连接"事件,以便计算登录"主页"页面和"新"页面的用户.
我试图在相对路径中配置socket.io'connection'事件,如:
app.get('/new',
function(req,res) {
io.sockets.on('connection', function (socket) {
.....
}
});
但:
怎么做到呢 ？
我在文本文件(test.txt)中有这个字符串:
BLA BLA BLA
BLA BLA
Found 11 errors and 7 warnings
我执行此命令:
findstr /r "[0-9]+ errors" test.txt
为了得到只是11 errors字符串.
相反,输出是:
Found 11 errors and 7 warnings
有人可以帮忙吗？
我有两个组件,一个使用另一个.
第一个是:"GamePanelComponent" 其中包含html文件:
"my-game-panel-output"tag
第二个是:
import { Component, Input } from '@angular/core';
@Component({
moduleId: module.id,
selector: 'my-game-panel-output',
templateUrl: 'gamepaneloutput.component.html',
styleUrls: [ 'gamepaneloutput.component.css' ]
})
export class GamePanelOutputComponent {
@Input()
message: string;
}
我写了一个测试GamePanelComponent:
import { ComponentFixture, TestBed, async } from '@angular/core/testing';
import { By } from '@angular/platform-browser';
import { DebugElement } from '@angular/core';
import { GamePanelComponent } from './gamepanel.component';
import { GamePanelOutputComponent } from '../gamepaneloutput/gamepaneloutput.component';
describe('GamePanelComponent (inline template)', () => {
let comp: GamePanelComponent;

以下是运行该服务的代码:
oServiceHost = new ServiceHost(typeof(API), new Uri(WebHookURL))
oServiceHost.Open();
正如您在此处所见 - 我WebHookURL在运行时获取服务URL().如上所述,URL协议可以是HTTP或HTTPS.
经过大量的阅读和测试,它归结为这个web.config文件:
<system.serviceModel>

这是我的代码:
private ListView listViewGameResults;
protected View dialogLayout;
protected ArrayList<Game> listGames;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.adresults);
GameResultsLoader gameResultsLoader = new GameResultsLoader();
gameResultsLoader.execute();
}
private class GameResultsLoader extends AsyncTask<Void, Void, Void> {
private GameResultsAdapter adapter;
public GameResultsLoader() {
}
@Override
protected void onPreExecute() {
}
@Override
protected Void doInBackground(Void... params) {
try {
listGames = GameResultsCache.getInstance().getGameResults();
adapter = new GameResultsAdapter(getBaseContext(), listGames);
listViewGameResults = (ListView)findViewById(R.id.listViewGameResults);
}
catch (Exception e) {
// TODO Auto-generated catch block
finish();
} …我想加入两个临时表。
这是我的桌子：
CREATE TABLE #Result ( Process varchar(50), SuccessCount int, FailureCount int)
CREATE TABLE #SuccessResult ( Process varchar(50), SuccessCount int)
CREATE TABLE #FailureResult ( Process varchar(50), FailureCount int)
我的表中有一些数据，这是我的查询：
INSERT INTO #Result (Process, SuccessCount, FailureCount)
SELECT s.Process,s.SuccessCount,f.FailureCount
FROM #SuccessResult s, #FailureResult as f
INNER JOIN #SuccessResult on f.Process = #SuccessResult.Process
我收到此错误：
找不到多部分标识符f.Process
我正在使用Microsoft SQL Server 2008。
我究竟做错了什么 ？
我有一个SQL数据库,我想转换为NoSQL(目前我正在使用RavenDB)
这是我的表格:
跟踪:
ID (PK, bigint, not null)
DeploymentID (FK, int, not null)
AppCode (int, not null)
部署:
DeploymentID (PK, int, not null)
DeploymentVersion (varchar(10), not null)
DeploymentName (nvarchar(max), not null)
应用:
AppID (PK, int, not null)
AppName (nvarchar(max), not null)
目前我的表中有这些行:
跟踪:
ID: 1 , DeploymentID: 1, AppCode: 1
ID: 2 , DeploymentID: 1, AppCode: 2
ID: 3 , DeploymentID: 1, AppCode: 3
ID: 3 , DeploymentID: 2, AppCode: 1
部署:
DeploymentID: 1 , DeploymentVersion: 1.0, DeploymentName: "Test1"
DeploymentID: …我正在尝试在事件处理程序中运行一个小部件.
由于某种原因,在事件处理函数内部不触发窗口小部件.此事件属于List.js,小部件属于paging.js.
var userList = new List('users',options);
userList.on('searchComplete', function () {
$('#testTable').paging({limit:5});
});
$('#testTable').paging({limit:5});
$('#testTable').paging({limit:5}); 搜索完成时该行会被激活 - 但由于某种原因它不会运行.

有帮助吗？
