c++ - Difference between (++i) and (i++) -

February 15, 2015

In C ++ I think that (++ i) is passed to i < / Code> Because operator needs to be added, but which I do not know:

  Why should  (i ++)  return  i  From the price? 
  Can anyone explain?

The form of ++ i << code> i Can be written in

  prefix_inc (this) code> is back, we can refer to it, however, looks like  i ++  < / P>   postfix_inc (this) {copy of this increase old_th = copy by 1 old old_this}  
  as  old_this  just There is a local variable, the reference is useless  i ++  is complete so logically it is a Should give justice.

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.

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.

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...
