visual studio 2012 - How keep the memory clear in the C# applications (DataTable dispose)? -


Is the best way to set up a DataTable and clear all the RAM memory related to the C # application? I have a simple code using {vDT} {vDT} using {DataTable vDTsec = New DataTable ()): 

  Private Zero Form 1_load (Object Sender, EventAgds E) {Datatale vDT = New DataTable ()). Columns.Add ('A'); VDT.Columns.Add ("B"); VDT.Columns.Add ("B_1"); VDTsec.Columns.Add ('A'); VDTsec.Columns.Add ("B"); VDTsec.Columns.Add ("e"); (Int x = 1; x & lt; = 1000000; x ++) {vDT.Rows.Add (New object [] {x, "B" + x.ToString (), "C" + x.ToString ()}); VDTsec.Rows.Add (new object [] {x, "B" + x.ToString (), "E" + x.ToString ()}); } VDT.Dispose (); VDTsec.Dispose (); } Gc. Compiler (); GC.WaitForFullGCApproach (100); GC.WaitForPendingFinalizers (); }

If I place a breakpoint before creating millions of rows then the application size is ~ 4MB:

after the construction of the lines, there has been a huge increase in memory (~ 428 MB):

Despite the disposal of both tables, the memory continues in 428MB:

First of all, you do not necessarily want to know about that number It should be seen in the Task Manager. This means that the garbage collector has not yet collected the memory (or the OS is caching the memory), and if the OS does not need it, then GC will collect it a little Late can wait.

The only compelling reason for better control of memory usage (beyond sensible object management) in your application is to improve the performance characteristics of your program. The way you do this, by using it, which basically means, instead of destroying and rebuilding objects, you make them once, and then use them again, so GC never Does not collect, but only use it if you have finished all other techniques to improve performance.

sqlite3 - UPDATE a table from the SELECT of another one -

I have the first table article where some data is missing. In the table, articles_tmp I have a part of the missing data. So I want to update the articles. Where the path path is data in articles_tmp.path where the path is not zero . With SQLite , it does not work: update article SET path = (SELECT at.path FROM Articles_tmp as AS, WHERE at.article_id = a.id and a.asp, the text is in the form and not on. It has been transmitted) where the path is null MS Access Along with, it works fine: Update Articles Join the Inner Articles at articles_tmp articles.id = articles_tmp.id SETP articles.path = articles_tmp.path Can anyone help? Sin CE SQL Server Syntax, which I provided, was not working, here this solution With whom I have come. A little modification of your original query, but with my "correlation" suggestion added. There is a SQL Bella for this: Here is the code: update article SET path = (SELECT path from articles_tmp AS T WHERE t.id

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ

javascript - Render HTML after each iteration in loop -

I'm trying to gradually increase the font size of text on a web page. The code works in my place, although the new HTML / CSS does not render after every iteration of the loop and when all this is done, then display only the text of 100 px size. To see the text as if it is slowly zooming, I need to do this JavaScript is down because it is being used from a different file here is what I have ... < Pre> & lt; P class = "game-title" style = "font-size: 50px" & gt; Test & lt; / P & gt; Function sleep (milliseconds) {var start = new date (). GetTime (); For (var i = 0; i & lt; 1e7; i ++) {if ((new date). GetTime () - start) & gt; Milliseconds {break; CSS ('font-size', 'parseInt ($ (' game-title '). CSS (' font-size ')) + 1 + "pixels"); } While (parasont ($ ('# text'). Css ('font-size')) & lt; = 100) {sleep (1000); IncreaseSize (); Using CSS: Use of jQuery (sample):
