Главное, что я понял

Главное, что я понял — это то, что в человеке заложено огромное количество сил и энергии. Если мы несем ответственность за свою жизнь, то мы эти силы направляем на вполне позитивные, правильные вещи — бизнес, карьера, построение качественной личной жизни. Если же мы предпочитаем пассивное времяпровождение — то нам остается интернет, ТВ, пиво и прочие прелести потребительского образа недожизни. Каждому — свое.

Но силы есть у всех.

microsoft.biztalk.interop.ssoclient error

I was trying to configure biztalk 2013 sftp adapter and was getting this error in EventLog
Reason: "System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.BizTalk.Interop.SSOClient, Version=7.0.2300.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.
It turns out that there is no BizTalk Interop SSOClient in the GAC

 
C:\Windows\system32>gacutil -l | find "Microsoft.BizTalk.Interop.SSOClient" 
  Microsoft.BizTalk.Interop.SSOClient, Version=5.0.1.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35, processorArchitecture=MSIL 
  Microsoft.BizTalk.Interop.SSOClient, Version=3.0.1.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35 

I resolved this problem by finding ESSO on Biztalk DVD and manually upgrade SSO and this resolved the problem :

 
C:\Windows\system32>gacutil -l | find "Microsoft.BizTalk.Interop.SSOClient" 
  Microsoft.BizTalk.Interop.SSOClient, Version=7.0.2300.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35, processorArchitecture=MSIL 

select count from all tables in database

SELECT table_name, row_count FROM #counts ORDER BY table_name, row_count DESC 

t-sql unit testing

Here is simple t-sql unit testing approach by writing sql script that will do all testing work.
I like this solution the most because it's very flexible and doesn't require additional installations on sql server.


Also I think the best way to write sql unit tests is to make them independent from data.And validate logic but not data.
Such unit tests can be run on development or qa and even production environment.

 
--Unit Test example  
--SETUP 
declare @ActualData varchar(10) , @ExpectedResult varchar(10) 
 
-- RUN 
SET @ActualData ='a' 
Set @ExpectedResult ='b' 
 
--  VALIDATE 
IF @ActualData!= @ExpectedResult 
        RAISERROR('>> Unit Test FAILED: Returned data doen''t match expected: %s instead of %s ', 11, 0, @ActualData ,@ExpectedResult  ) 

Also there are another sql unit test frameworks .

html.radiobuttonfor onclick for tracking change event

here is example how to use onclick event for tracking changes in radio button group.

 
	@Html.LabelFor(m => m.BoolProperty) 
	@Html.RadioButtonFor(m => m.BoolProperty, true, new {  onclick= "onPropertyChanged(true);" }) 
	@StringResources.Submitted 
	@Html.RadioButtonFor(m => m.BoolProperty, false, new { onclick = "onPropertyChanged(false);" }) 
	@StringResources.Fulfillment 

so when radio button control will be changed , onPropertyChanged javascript function will be called passing value of radio button as argument.

c# datetime beginning of day

This extension adds EndOfDay StartOfDay methods to DateTime so it's possible to call
DateFrom.Value.StartOfDay() or dateTo.Value.EndOfDay()

 
using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Text; 
namespace AwesomeExtensions 
{ 
 
        public static class Extension 
        { 
                public static DateTime EndOfDay(this DateTime date) 
                { 
                        return new DateTime(date.Year, date.Month, date.Day, 23, 59, 59, 999);

accessed from a thread other than the thread it was created on.

This happends when you are trying to modify control from another thread.You cannot do this directly it could be done only by invoker.
In order to resolve this situation please do following:
step 1: Create following extension

 
using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Text; 
using System.Windows.Forms; 
 
        public static class Extension 
        { 
                public static void InvokeIfRequired(this Control control, MethodInvoker action) 
                { 
                        if (control.InvokeRequired) 
                        { 
                                control.Invoke(action); 
                        } 
                        else 
                        { 
                                action(); 
                        } 
                } 
        } 

step2.Using developed extension:
Now in other thread instead of calling control directly like :

 
htmlPanel1.Text = resml;  

You have to call it as follows:

 
htmlPanel1.InvokeIfRequired(() =>{ htmlPanel1.Text = resml; }); 

@html.dropdownlistfor onchange

jquery save and restore form data

Here is sample how to store and retrieve form and retrieve data

 
// get all form values into json  
var s2=$('form').values(); 
// restore all forms values back

Here is the function

    
/* function for form saving restoring code */

        var els = $(this).find(':input').get(); 
 
        if (typeof data != 'object') { 
                // return all data

                        } 
                }); 
                return data; 
        } else { 
                $.each(els, function () { 
                        if (this.name && data[this.name] != null) { 
                                //console.log(">" + this.name + " " + data[this.name]); 
                                if (this.type == 'checkbox') {

mvc get html from view

add method below to controller then you will be able to get html from any view by:
this.RenderView("myView");

 
	/// <summary> 
        /// get html from view  
        /// </summary> 
        public string RenderView(string ViewName) 
        { 
            var content = string.Empty; 
            var view = ViewEngines.Engines.FindView(ControllerContext, ViewName, null); 
            using (var writer = new StringWriter()) 
            { 
                var context = new ViewContext(ControllerContext, view.View, ViewData, TempData, writer); 
                view.View.Render(context, writer); 
                writer.Flush(); 
                content = writer.ToString(); 
            } 
            return content; 
        } 

asp.net mvc ajax post model

If model contain variable of class Class1 with properties Property1,Property2.
Submitted parameters must be named:
"Class1.Property1"
"Class1.Property2"

If model has property as List<Record> submitted values must be :
"Class1[0].Property1"
"Class1[0].Property2"
"Class1[1].Property1"
"Class1[1].Property2"
"Class1[2].Property1"
"Class1[2].Property2"

Here are samples of two functions that creates this values dynamically before submitting form.

     
//this function create parameters for sending them over AJAX 
function ConvertJSONIntoPostableHTML() { 
var params = { 
            param1 : 'myvalue', 
        }; 
 
if (Jsonrecord != null) { 
    for (var i = 0; i < Jsonrecord.length; i++) { 
        var rec = Jsonrecord[i]; 
        $.each(Object.keys(rec), function(j, value) { 
            params["Records[" + i + "]." + value] = rec[value]; 
        }); 
    } 
} 
 
return params; 
} 

        
 
//this function add parameters to form , then form can be submitted  
function SelectedNodes(frm) { 
            $(".tslct").remove(); 
            var i = 0; 
                $.each(myJsonCollection, function () { 
                                var obj = "Nodes[" + i + "]."; 
                                addElem(frm, obj + "Id", this.Id); 
                                addElem(frm, obj + "Value", this.Type); 
                                i++; 
                } 
        ); 
} 

jquery add element to form dynamically

 
//function that adds element to form  
function addElem(frm, id, val) { 
                $('<input>').attr({ 
                        type: 'hidden', 
                        id: id, 
                        name: id, 
                        value: val, 
                        class: 'tslct' 
                }).appendTo(frm); 
} 
 
//example of using of this function  
var frm = $(this).closest('form'); 
addElem(frm,  "myId", "myvalue"); 

use of hashtable in javascript

here is an example of usage of hashtable in javascript.For example I want to asociate specific buttonId
with specific grid Id I could create following hashtable:

 
var GridsButtons = { 
'AGroupsListGrid' :'DelA', 
'BGroupsListGrid' :'DelB' 
}; 

Then I could use it in code :

 var buttonid = GridsButtons[gid]; 

asp.net mvc ajax post from javascript

Following example demonstrate how to submit form in asp.net MVC for strict type view based on model:
(view has this instruction oin top:
@model MyModel
):

javascript part:

      
<script type="text/javascript"> 
    $(document).ready(function() { 
        $("#GoButton").click(function() { 
            var frm = $(this).closest('form'); 
            var params = frm.serialize(); 
             $.ajax({ 
                                type: 'POST', 
                                url: '@Url.ApplicationAction("MyPostAction", "myController")', 
                                data: params, 
                                cache: false, 
                                success: function (data) {                                     
                                  alert('Completed');  
                                }, 
                                error: function (xhr, data, message) { 
                                    //console.log(data + ": " + message); 
                                }, 
                                dataType: "json" 
                            }); 
            return false; 
        }); 
    }); 
</script> 

on server side model variable will have updated with all values submitted in form and will have following parameters:

 
[HttpPost] 
public ActionResult MyPostAction(MyModel model) 
{ 
 
 return Json("Ok"); 
} 

jquery events with example

Following example demonstrate how to use jQuery events:
To trigger event use this code :

 $document.trigger('Grid_CheckBox_Click',gridId,this); 

Grid_CheckBox_Click is the name of my event.

to Subscribe to event use this code:

 
$(document).bind('Grid_CheckBox_Click', function (e, elem) { 
MyFunction(e); 
}); 

mvc radiobuttonfor example

below is an example of creating mvc radio button control for boolean model myBoolProperty property

 
@Html.LabelFor( m => m.myBoolProperty) 
@Html.RadioButtonFor(m => m.myBoolProperty, true) 
@StringResources.Submitted 
@Html.RadioButtonFor(m => m.myBoolProperty, false) 
@StringResources.Fulfillment 

mercurial server multiple repositories

Уроки

Урок 1 (он же главный): Найдите наикратчайший из способов удовлетворить потребность и не напрягайте пользователей деталями.

Нам через день предлагают добавить ту или иную фишку. Первый вопрос которым мы задаемся — а какому проценту наших пользователей это понадобиться. Если меньше 5% — мы этого делать не будем.

Урок 2 (вообще-то продолжение первого): ненужная большинству функциональность вредна поскольку усложняет понимание.

Вот как мы расправились с некоторыми из сложностей:

1. Программа должна была работать с несколькими проектами/работами. Однако для большинства достаточно создать только один проект выбрав несколько баз для бэкапа. Мы сделали так, что программа сама открывает тот же проект, что и в прошлый раз и соединяется с тем же SQL сервером — так что большинство даже и не задумывается, что можно работать с несколькими проектами.
2. SQL Connection String — до сих пор самая сложная часть для пользователя. При первом запуске мы, не спрашивая пользователя, перебираем самые распространенные Connection String, так что, открыв программу, большинство пользователей уже подключились к серверу и видят список своих баз данных.
3. Посылка писем — чтобы не напрягать пользователей с настройкой SMTP мы по умолчанию посылаем письма через веб-сервис на своем сервере. Для бесплатных пользователей фишка бесплатна на неделю, а потом можно либо купить платную версию либо пользоваться своим Gmail или другим SMTP сервером.
4. Расписание — большинству требуется Full Backup один раз в день. Что и можно сделать на основной форме. Для более продвинутых все настройки спрятаны за кнопкой Settings.

Деньги

Поработав немного, мы сделали первую версию программки. Далее мы поставили ее во все shareware-сайты и оставили комментарии на форумах по этой теме. Понемногу пошли клиенты. Через два месяца после выпуска нас заметила одна большая компания, продукт которой был основан на SQL и его пользователи с небольшими техническими знаниями были сами ответственны за бэкап. Для них мы подходили идеально и они послали всех своих пользователей к нам. Кроме этого они даже взяли на себя заботу по тех поддержке. Деньги потекли рекой.

Основная версия (Standard) стоит сейчас $59. Для тех компаний для которых это не деньги — у нас есть Professional с добавкой AES encryption за $69. Для экономных — Lite (максимум 5 баз данных) за $29. С год назад я прочитал какую-то статью о том, что цены на странице Prices нужно подавать от больших к малым дабы пользователю, испуганному первыми большими цифрами, цифра в середине показалась относительно скромной. Мы подумали: что бы такого выпустить дорогого чтобы пугать пользователей? Так родилась идея Lifetime-версии за $199 (сейчас $149) с бесплатными пожизненными обновлениями. И мы очень удивились когда ее стали бодро покупать!

Потом товарищ подкинул другую идею, которая принесла тысячи долларов. В добавок к продуктам мы продаем за небольшие деньги еще и Extended Support (тем, кто его купил — особое внимание при поддержке) и бесплатное обновление на 1 год (по умолчанию — 1 месяц). Дополнительные усилия близки к 0, а деньги понемногу капают…

Урок 3 — дайте пользователю заплатить столько, сколько он хочет и может.

Пиратство и жадность

С первых дней существования мы решили тратить только минимум времени на борьбу с пиратством. В программе зашит алгоритм на проверку лицензионного ключа который несложно взломать. Идея такова: если человек запускает keygen для взлома — он вряд ли заплатил бы за программу без этого. А так — будет пользоваться и, возможно, когда остепенится, тогда и почувствует потребность заплатить.
Многие устанавливают ключик на несколько машин — мы просто посылаем вежливые письма с напоминанием, что это неправильно. Компании в цивилизованных странах стараются договоренности соблюдать и покупают недостающие лицензии. С менее цивилизованными мы могли бы справиться добавив активацию, но это усложнило бы жизнь для большинства честных клиентов. И опять же: нами пользуются и это уже хорошо.

Урок 4 — концентрируйтесь на продукте, а не на защите. Пират сегодня — клиент завтра.

Большинству вполне хватает бесплатной версии в которой можно делать то же самое, что и в стандартной, только с ограничением в две базы данных. Благодарный народ даже пожертвования предлагает. Да мы и рады: когда потребности вырастут, тогда и заплатят, а заодно боремся с бесплатными самоделками.
Недавно мы добавили бэкапы в Amazon S3, Google Drive и Dropbox. Сначала было желание брать дополнительные деньги. Но решили не напрягать пользователей и просто добавить к существующим версиям. Будет больше пользователей — значит и доходы вырастут.

Урок 5 — довольные клиенты важнее сиюминутного наполнения карманов.

py2exe mechanize

I've got problem with including mechanize into py2exe package.
I resolved this problem by

1. uninstalling packages by running easy_install with -m key

         easy_install -m  mechanize
         easy_install -m MultiPartPostHandler        
        

1. physically removing .eggs files from python2.X/site-packages/MYPACKAGE.egg

1. installing packages with -Z key

        easy_install.exe -Z mechanize 
        easy_install.exe -Z MultiPartPostHandler

reset sa password sql 2008

How to recover SA password on Microsoft SQL Server 2008 R2

When you are using MS SQL Server in mixed mode, it is very important that you know your SA password.

There can be different reasons you lost the password

• Person who installed the SQL Server knows the password but has left the building.
• You did not write down the password in your password file
• Password file is lost
• …

Steps to recover the SA password

• Start SQL Server Configuration Manager
  

• Stop the SQL services
  

• Edit the properties of the SQL Service
  

• Change the startup parameters of the SQL service by adding a –m; in front of the existing parameters
  

  

• Start the SQL services. These are now running in Single User Mode.
• Start CMD on tthe SQL server
• Start the SQLCMD command. Now you will see following screen
  

• Now we create a new user. Enter following commands
  • CREATE LOGIN recovery WITH PASSWORD = ‘TopSecret 1′ (Remember SQL server has default strong password policy
  • Go
    • Now this user is created
• Now we grant the user a SYSADMIN roles using the same SQLCMD window.
  • sp_addsrvrolemember ‘recovery’, ‘sysadmin’
  • go
• Stop the SQL service again
• Change the SQL service properties back to the default settings
  

• Start the SQL service again and use the new created login (recovery in my example)
• Go via the security panel to the properties and change the password of the SA account.
  

• Now write down the new SA password.
