...it's me...eRiCk

 it's been a long time since my last post i will try to blog again in my journey the journey paths will be in: Blazor, IIS, Crystal Report, SAP Business One, ClickOnce, Nuget, SQL Server Query. most will be using MS tech of course until then

Hi, Long time no post, i will try to post again since i came out searching a typical solution over and over again :D Now i'm gonna post about session. Since i got this from other link so here it is So I started looking into the IIS settings and came to know that i missed two things to change : Application pool’s Idle Time-out (minutes) Session state  – State server’s Time-out (seconds) Once I have changed above settings than after Session timeout worked. So after that I have made one checklist that can help us to validate Session timeout settings, here i am sharing it with you as well so that you will also get some benefits from it : Application Pool  – Advanced Settings Menu – Process Model – Idle Time-out (minutes) Sites –  Session State  – Cookie Settings – Time-out (minutes) If you are using  State Server  or  SQL Server  to manage your session (instead of InProcess), Here is the steps to follow :    ...

In previous months, i have opportunity to play along with MVC after a while using EF Code First and MVC 5. So today the snippet about creating DropdownList from object List rather than List of SelectListItem let's say u have this Company Class [Key] public int CompanyId { get; set; } public string Name { get; set; } public string Code { get; set; } and u want to display dropdown list based on Code as Text and Id as Value in the View u create a SelectList based on that field @Html.LabelFor(model => model.Brand.Company, htmlAttributes: new { @class = "control-label col-md-2" }) @Html.DropDownList("selectedCompany", Model.Companies.Select(_ => new SelectListItem { Text = _.Code, Value = _.CompanyId.ToString(), Selected = _.CompanyId.ToString() == Model.Brand.Company.CompanyId.ToString() }) ) the Model is a simple ViewModel that have Brands and Brand object sorry for the format, can not make it right :D

i just starting to play along with SSIS and SSAS and i came up with this trick to show wether my data has been populate into staging or data warehouse table so here is the script EXEC sp_MSForEachTable " DECLARE @count AS INT SET @count=0 SELECT @count = ISNULL(SUM(1), 0) FROM ? PRINT ""?: "" + CONVERT(VARCHAR, @Count) , @whereand = "ORDER BY 1" "  until then

hi all, just remember to post this useful tips -- disable all constraints EXEC sp_msforeachtable "ALTER TABLE ? NOCHECK CONSTRAINT all" -- delete data in all tables EXEC sp_MSForEachTable "DELETE FROM ?" -- enable all constraints exec sp_msforeachtable "ALTER TABLE ? WITH CHECK CHECK CONSTRAINT all" --if some of the tables have identity columns we may want to reseed them EXEC sp_MSforeachtable "DBCC CHECKIDENT ( '?', RESEED, 0)" see u then

usually i will using temporary table to build dynamic query to compare the value for two indentical database between two servers but few weeks ago i know undocumented sp_msforeachtable stored procedure and gain some advantage for using it exec sp_MSforeachtable  @command1 = ' IF EXISTS( SELECT top 1 * FROM [server2].db_name.? EXCEPT  SELECT top 1 * FROM ?   ) PRINT ''?'' ' just make sure u use "." in first syntax because sp_msforeachtable return "dbo.table_name" for parameters reference please see this link see u

it can :D u have to publish it to iis i think, not testing when publish it using ftp just add this line "C:\Program Files\Internet Explorer\iexplore.exe" http://yoururltoapplication/applicationname .application just make sure u put the red word at behind until then

currently there are needs to add some shortcut based on ClickOnce Application that being deployed, it's obvious we can't create it manually because of the installation path here is some remedy :D, u need to add reference to System.Deployment, System.IO,  System.Reflection  if (ApplicationDeployment.IsNetworkDeployed) { string publisherName = ((AssemblyCompanyAttribute)Attribute.GetCustomAttribute(Assembly.GetExecutingAssembly(), typeof(AssemblyCompanyAttribute), false)).Company; string productName = System.Reflection.Assembly.GetExecutingAssembly().GetName().Name; string startupPath = Environment.GetFolderPath(Environment.SpecialFolder.Startup); startupPath = Path.Combine(startupPath, productName) + ".appref-ms"; if (!File.Exists(startupPath)) { string allProgramsPath = Environment.GetFolderPath(Environment.SpecialFolder.Programs); string shortcutPath = Path.Combine(allProgramsPath, publisherName); shortcutPath = Path.Combine...

if u plan to check how much your database growth then u might need this script from  Yaniv Etrogi it writes the growth to database so u can check it againts database threshold that u define best of it: all the scripts already provided :D until then

hi, just came across a very good script from Pinal Dave u can see all database information in one place here the script SELECT database_id, CONVERT(VARCHAR(25), DB.name) AS dbName, CONVERT(VARCHAR(10), DATABASEPROPERTYEX(name, 'status')) AS [Status], state_desc, (SELECT COUNT(1) FROM sys.master_files WHERE DB_NAME(database_id) = DB.name AND type_desc = 'rows') AS DataFiles, (SELECT SUM((size*8)/1024) FROM sys.master_files WHERE DB_NAME(database_id) = DB.name AND type_desc = 'rows') AS [Data MB], (SELECT COUNT(1) FROM sys.master_files WHERE DB_NAME(database_id) = DB.name AND type_desc = 'log') AS LogFiles, (SELECT SUM((size*8)/1024) FROM sys.master_files WHERE DB_NAME(database_id) = DB.name AND type_desc = 'log') AS [Log MB], user_access_desc AS [User access], recovery_model_desc AS [Recovery model], CASE compatibility_level WHEN 60 THEN '60 (SQL Server 6.0)' WHEN 65 THEN '65 (SQL Server 6.5)' WHEN 7...

the key is to set minimum requirement version to be exactly like the one u published right now to remove the update popup dialog when starting clickonce program just make sure the version is the same between Publish version and Update the Project properties - Publish until then

hi, just got an error for couple of days when try to return a model contain child record using Entity Framework and DBContext i have this Role class that contain list of User within that Role so when i try to get specific Role along with the User it give me an error "The underlying connection was closed " after searching alot i came up with this great solution disabled proxy creation and lazy loading or  manually in Entity DBContext constructor it run succesfully and can return UserInRole but if i filled up the table then the error comes, so we need to  Preserving Object Reference in WCF  but i came with this very useful  Andrey Chabster Blog  that using custom attribute that needed for the Service contract and Operation contract  until then

hi again,  just came up with this error in Entity Framework  the reason is because my development using SQL2008 express edition but the preproduction using SQL2005 and the solution is fairly simple  Open your EDMX in a file editor (or “open with…” in Visual Studio and select XML Editor). At the top you will find the storage model and it has an attribute ProviderManifestToken. This has should have the value 2008. Change that to 2005, recompile and everything works after trying up for 2 hours :D until then

hi all, found another intresting stuff to post scenario: u change windows computer name and suddenly the query that contains SQL Server link server or anything that currently connect to ur "changed computer" is not working try using this query in SSMS -– Get the current name of the SQL Server instance for later comparison. SELECT @@servername –- Remove server from the list of known remote and linked servers on the local instance of SQL Server. EXEC master.dbo.sp_dropserver ‘[SERVER NAME]‘ –- Define the name of the local instance of SQL Server. EXEC master.dbo.sp_addserver ‘[NEW SERVER NAME]‘, ‘local’ –- Get the new name of the SQL Server instance for comparison. SELECT @@servername after try, u must restart sql server services...then check if the query is working now see u

hi, just want to post something that might be useful DECLARE @a AS TABLE ( autoid INT  , name VARCHAR(20) , parentid INT ) INSERT INTO @a (autoid, name, parentid) SELECT 1, '1', 0 UNION ALL SELECT 2, '1.1', 1 UNION ALL SELECT 3, '1.2', 1 UNION ALL SELECT 4, '1.2.1', 3 UNION ALL SELECT 5, '2.1', 2 UNION ALL SELECT 6, '3.1', 3 UNION ALL SELECT 7, '3.2', 3 /* 1 1 0 2 1.1 1 3 1.2 1 4 1.2.1 3 5 2.1 2 6 3.1 3 7 3.2 3 */ /* Get Parent Records from child '1.2.1' return: 1.2 (parent from '1.2.1') 1 (parent from '1.2') */ ;WITH    employeeMaster       AS ( SELECT   p.autoid ,                     p.parentid ,                     p.[name]            FROM     @a p            WHERE ...

here is the script from my colleague if u want to convert DATETIME data type to SMALLDATETIME because simple CONVERT is not working SELECT CONVERT (SMALLDATETIME, CONVERT (VARCHAR, GETDATE(), 103), 103) until then

my colleague needs a query to seek for all tables in certain Database then use it to display informati on such as: Created Date, Rows in that tables, etc at first i look over sp_spaceused but it end up wrapping query which is hard because undocumented and it failed :( also considerations can be used for SQL 2000 so i google it and found this link , it works for SQL 2000 and above i tweak a bit to meet my requirement but credit goes to  Richard Ding here is the query that i used USE master; GO IF OBJECT_ID(N'dbo.sp_SOS', N'P') IS NOT NULL   DROP PROCEDURE dbo.sp_SOS; GO CREATE PROCEDURE dbo.sp_SOS   @DbName sysname = NULL,   @SchemaName sysname = NULL,   @ObjectName sysname = N'%',   @TopClause nvarchar(20) = NULL,   @ObjectType nvarchar(50) = NULL,   @ShowInternalTable nvarchar(3) = NULL,   @OrderBy nvarchar(100) = NULL,   @UpdateUsage bit = 0 AS /*=============================================================...

i know it's "old" one but sometimes i need to use it so instead i search over and over again, i'll write it down here :D the magic word are (at command prompt) nbtstat -a [ip_address_here] until then
