c# - Will this safely delete my record? -

January 15, 2015

I hate these three tables, there are many relationships in two tables and as such it generates a third of the table.

I used Linq- To-SQL and .dbml files, I've dragged all the folders to the graphic surface there.

Here I am using an area to safely remove Remember that documents are connected to a region, so I can not delete it and leave the document hanging.

  ScansDataContext db = new ScansDataContext (); /// & lt; Summary & gt; Deletes Area Objects from Database with All Associations in the /// Database. /// & lt; / Summary & gt; /// & lt; Ultimate name = "area" & gt; To save the area object & lt; / Param & gt; Public Zero Removal (Area Areas) {db.DocumentAreaRelations.DeleteAllSubmit (field.Documentary Array Reference); Db.Areas.DeleteOnSubmit (field); Db.SubmitChanges (System.Data.Linq.ConflictMode.FailOnFirstConflict); }      
  Believing that you still have to implement relationships There are obstacles in the database. It seems that I should be good to go. If you do not have the keys to the database, then you have to add them.  
 You want to delete all the relationships first, second the actual unit and  submit ()  wrap everything in a local transaction so that it is a unit of work.

Unable to get a fresh ASP.NET MVC project running with Visual Studio
2008 -



    This is a very basic question. I'm asking this silly about this, but I'm stuck something else and hopefully That something here can save me some time. So I open VS2008, to download the new ASP.NET MVC web application and click OK I want to prepare a test project. I debug my new MVC project to hit F5 then I enable the debugging to the web. I choose to modify the config file. It goes where I get a page load error.   Firefox can not establish a connection to the server on the local host: 57323.   Do I have to do something special for Vista? Or I should do something with IIS   Thanks for helping a noob   6/30/2009 update   OK, I think that I VS2008 may need to be reinstalled with the ASP.NET Development Server port. I have tried to do everything that I have suggested. I've marked Default.aspx as the start page. I tried to open it in Firefox / IE 8 / and Chrome. I tried to uninstall / reinstall ASP.NET MVC, which was not working. I tried telnetting with Putin with a local ho...






delphi - Mouseover hint for TChart series value -



    I am using a TChart in Delphi 7, and I want to display charts sometime. I am using the following code to set the chain value to a database query:    chart1.FreeAllSeries; Chart1.SeriesList.Clear; Chart1.AddSeries (TBarSeries.Create (self)); TBarSeries (chart1.Series [0]) BarStyle :. = BsRectGradient; Stop starting with Query 1; Executed; While EOF does not start chart1.Series [0]. Add (field 'flags' ('sum_actual_days'), Field Astrstring ('contract_no')); the upcoming; End; End;    Each time (value) is now showing both the label below the bar and in a yellow rectangle above the bar.   Rather than repeating the amount of label twice, I have some additional information from the query that I would like to show above the bar rather than the label (or, preferably, as a mouseover signal). Can it be done with TChart? And how ...?      This can be done with a TChart using the onMouseMeave event of the chart. Something like this should start with you:    Process TForm...






sql - Incorrect syntax near the keyword 'table' -



    I'm getting this error what I'm doing is trying to get data from a table and a db and Keep it in another DB and table. The tables are not exactly the same, I am using a FETCH cursor, so I get the first line from the DB1 table and then keep each column value in the declared variable. Then I run an assembly statement in db2 table and get the next value. All of these are working properly because it runs properly, but in the end I get this error,   Wrong syntax near the keyword 'table'.   In the entire transaction details, an attempt / catch with the error of expression in the Cat block, apart from this, I do not know what is the reason for it.   Here is the code    added to prevent additional result set at SET NOCOUNT - Interfering with the SELECT statement. Set nosenate on; TRY begin transaction sets ITENDITY column off --TURN identity_insert [dB] start [dbo] [TEST] all CONSTRAINTS table --TURN [dB] change [dbo] [TEST] NOCHECK barrier All -....
