我有日期和时间的DatePicker和TimePicker.现在我想将选定的日期和时间更改为毫秒.我怎样才能做到这一点？？？

例如,我选择了日期2-5-2012,时间是20:43

现在我有这个日期时间转换成毫秒像

DateTimeInMilliseconds =1234567890

我有一个存储过程

ALTER PROC TESTLOGIN
    @UserName varchar(50),
    @password varchar(50)
As
Begin
    declare @return int;

    set @return  = (SELECT COUNT(*) 
                    FROM CPUser 
                    WHERE UserName = @UserName 
                    AND Password = @password);

    return @return;
End

并在c#

SqlConnection con = db.con;
SqlCommand cmd = new SqlCommand("TESTLOGIN", con);
cmd.CommandType = CommandType.StoredProcedure;

SqlParameter parm = new SqlParameter("@return", SqlDbType.Int);
parm.Direction = ParameterDirection.ReturnValue;

cmd.Parameters.Add(parm);
cmd.Parameters.Add(new SqlParameter("@UserName", txtUserName.Text.ToString().Trim()));
cmd.Parameters.Add(new SqlParameter("@password", txtPassword.Text.ToString().Trim()));

cmd.ExecuteNonQuery();
con.Close();

int id = Convert.ToInt32(parm.Value);

但它总是返回0.请帮我解决这个问题

我正在使用以下代码在数据库中创建多个表.但是,我不明白为什么会出现这个问题.

private static final String TABLE_SMSFilter = "SMSFilter";


public void onCreate(SQLiteDatabase db)
    {
        Log.d("Test", "Control is in Oncreate()");
        String CREATE_SMSSSCHEDULE_TABLE = "CREATE TABLE " + TABLE_SMSSchedule
                + "(" + KEY_ID + " INTEGER PRIMARY KEY autoincrement,"
                + KEY_NUMBER + " TEXT)";

        String CREATE_PROFILE_SCHEDULE_TABLE = "CREATE TABLE "
                + TABLE_ProfileSchedule + "(" + ProfileSchedule_ID
                + " INTEGER PRIMARY KEY autoincrement,"
                + ProfileSchedule_NUMBER + " TEXT, "
                + ProfileSchedule_ProfileMode + " TEXT,"
                + ProfileSchedule_CalendarID + "INTEGER)";

        String CREATE_SMS_FILTER_TABLE = "CREATE TABLE " …

我的SQL查询有问题

我想选择DISTINCT StudentGroups(SG),但查询给了我一些重复

这是我的查询

SELECT      DISTINCT(SG.SGID), en.EnrollmentID, CR.Name AS Course, INS.Name as Instructor,
                S.Session, SG.StartTime, SG.EndTime, EN.CreateDate

    FROM        StudentGroups SG inner JOIN Enrollments EN ON SG.SGID = EN.SGID
                JOIN Courses CR ON SG.CourseID = CR.CourseID
                JOIN Class CL ON SG.ClassID = CL.ClassID
                JOIN Instructors INS ON SG.InstructorID = INS.InstructorID
                JOIN Sessions S ON SG.SessionID = S.SessionID

    WHERE       EN.SGID NOT IN ( SELECT SGID FROM Enrollments
                            WHERE StudentID = 45

更新

此查询为我提供了以下数据

但我不想重复SGID

我正在制作一个短信计划应用程序,它只需要用户的时间,短信和号码,并在给定时间发送短信.我在用PendingIntent.这是我的示例代码.

当用户创建计划时,它只是调用此方法.

private void SendMessages()
    {
        Intent intent = new Intent(this, SMSBroadcastReceiver.class);
        PendingIntent pendingIntent = PendingIntent.getBroadcast(
                this.getApplicationContext(), 234324243, intent, 0);

        AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
        alarmManager.set(AlarmManager.RTC_WAKEUP, Timemilli, pendingIntent);
    }

这是'SMSBroadcastReceiver.java'文件

public class SMSBroadcastReceiver extends BroadcastReceiver
{
    @Override
    public void onReceive(Context context, Intent intent)
    {
        Toast.makeText(context, "SMS Sent !!!!.", Toast.LENGTH_LONG)
                .show();
        // //Sms Sending

        try
        {
            SmsManager smsManager = SmsManager.getDefault();
            for (int i = 0; i < SMSScheduleContactsActivity.SelectedContacts.length; i++)
            {
                smsManager.sendTextMessage(
                        SMSScheduleContactsActivity.SelectedContacts[i], null,
                        AddNewSmsSchedule.Message, null, null);
            }

            Log.d("testllllllllllllllll", "Message …

如何使用c#从asp.net中的sql数据库中检索图像.

我想从数据库中检索图像文件,然后在标签中显示图像.

我尝试这个代码,但它无法正常工作

ASPX

 <asp:Image ID="Image1" runat="server" ImageUrl="" Height="150px" Width="165px" />

代码背后

 Byte[] bytes = (Byte[])ds.Tables[0].Rows[0]["image"];
 Response.Buffer = true;
 Response.Charset = "";
 Response.Cache.SetCacheability(HttpCacheability.NoCache);
 Response.ContentType = "image/jpg";
 Response.BinaryWrite(bytes);
 Response.Flush();
 Response.End();

如何给出ImageUrl=""这个图像的链接???

我想从android日历中检索最后添加的事件的数据.我正在使用此代码获取最后一个ID.

 public static long getNewEventId(ContentResolver cr, Uri cal_uri)
 {
        Uri local_uri = cal_uri;
        if (cal_uri == null)
        {
            local_uri = Uri.parse("content://com.android.calendar/events");
        }
        Cursor cursor = cr.query(local_uri,
                new String[] { "MAX(_id) as max_id" }, null, null, "_id");
        cursor.moveToFirst();
        long max_val = cursor.getLong(cursor.getColumnIndex("max_id"));
        return max_val + 1;
 }

然后我只需使用以下代码添加一个事件:

Intent intent = new Intent(Intent.ACTION_EDIT);
intent.setType("vnd.android.cursor.item/event");
intent.putExtra("beginTime", SelectedDate);
intent.putExtra("allDay", false);
intent.putExtra("rrule", "FsREQ=DAILY");
intent.putExtra("endTime", SelectedDate + 60 * 60 * 1000);
intent.putExtra("title", "Advance Scheduler Event");
startActivity(intent);

在此之后,我只需使用以下代码检索此事件的数据:

public CalendarData EventDetails(int …

如何填补Object Array内部LINQ Query

这是我的数据模型

public class Test
    {
        public string Link { get; set; }
        public string Title { get; set; }
        public string Description { get; set; }
        public Item[] Items { get; set; }
    }

 public class Item
    {
        public string Title { get; set; }
        public string Link { get; set; }
        public string Guid { get; set; }
        public DateTime PublishDate { get; set; }
        public string Description { get; set; }
    } …

我有一个gridview有以下列

Delete | Name | ContactNo | EmailID | CreateDate |

删除列是自动生成的,我想在右侧移动它

 | Name | ContactNo | EmailID | CreateDate | Delete

我怎样才能做到这一点？？？

我的表格中有一个文本框.JavaScript 当用户在文本框中输入一些值然后按下Enter按钮时,我编写了一个函数来添加一些功能.当我按下Enter按钮时,首先,它执行我的JavaScript功能,但然后它显示验证消息(它提交表单).如何解决这个问题呢

这是我的texbox

<asp:TextBox ID="txt_CopyFrom" runat="server" onkeypress="searchKeyPress(event);" ClientIDMode="Static"></asp:TextBox>

这是我的JavaScript功能

function searchKeyPress(e) {
        if (e.keyCode === 13) {
                .
                .
                .

        }
        return false;
}

我有一个表股票

StockID   ItemID   Quantity   Price

现在我想选择一些像这样的数据

StockID   ItemID   Quantity Price   TotalPrice(Quantity*Price)

我试过这个

ALTER PROC [dbo].[SelectItemStock] 
@Item   int
as
BEGIN
    SELECT  Stock.*, (SELECT Quantity*Price FROM Stock) AS TotalPrice
    FROM    Stock
    WHERE   ItemID = @Item
END

但它给了我错误 Subquery returned more than 1 value.

请帮我解决这个问题

我试图按日期排序我的json数据,但它不起作用.这是我正在尝试的.请纠正我错误的地方

示例代码

var temp = [{
    "id": 17608,
    "title": "abc",
    "start": "2016-03-23 06:13:00.0",
    "backgroundColor": "#000000",
    "borderColor": "#000000",
    "textColor": "#fff"

console.log(temp);

temp.sort(function(a, b) {
