How to run the mutex code in c#.net on button click event? -


This is my code, which I have in my C #. 3.5 tried to run in the program but I am getting errors, what is the error?

Error CS0115: 'Form 1. Dispute (Boole) ': No suitable method was found for override

This is the code where I got the error: 

  Protected Override Zero Disposing) {If (disposal) {this._userConnectionOption = null; This._poolGroup = null; This.close (); } This.DisposeMe (settlement); Base.Dispose (settlement); }

Actual coding starts from here:

Program.cs: 

  using the system; Using System.Collections.Generic; Using System.Windows.Forms; Using Pu; Namespace WindowsApplication1 {Static class program {{STAThread} static zero Main () {// If this program is already running, set the Focus // for that example and leave it (ProcessUtils.ThisProcessIsAlreadyRunning ()) { // Caption (text property) of main form "Form 1" is ProcessUtils.SetFocusToPreviousInstance ("Form1"); } Other {application.availableviewual style (); Application.SetCompatibleTextRenderingDefault (wrong); Application.Run (New Form 1 ()); }}}}

ProcessUtils.cs: 

  using the system; Using System.Diagnostics; Using System.Threading; Using System.Windows.Forms; Using System.Runtime.InteropServices; Summary Details for Namespace Pu /// Process Utilis Public Static Class ProcessUtils {Private Static Mutex mutex = null; /// If the current process is already running public static bool then determine that this process is an ISL () {// only once, this method is called at startup. Debug Asperts (mutes == free); // created Net 2.0 needs to be incorrect, otherwise, if this is the second instance of //, then this program must be run, the Mutex constructor will block, and then throw an exception if another installation is off. Bool Made New = False; Mute x = new mute x (wrong, application, product name, new created out); Debug Asset (mute x! = Null); Come back! Created new; } [DllImport ("user32.dll", SetLastError = true)) static extern IntPtr FindWindow (string lpClassName, string lpWindowName); [DllImport ("user32.dll") [Return: Marshall AS (Unmanaged Type Bowl)] Static External Bull SetOnged Window (Intupetated HWW); [DllImport ("user32.dll")] Fixed external bull ISI (Indiport HTM); [DllImport ("user32.dll")] Fixed External Ball ShowWindow (IntPtr hWnd, int nCmdShow); Const int SW_RESTORE = 9; [DllImport ("user32.dll")] static extern IntPtr GetLastActivePopup (IntPtr hWnd); [DllImport ("user32.dll")] Static External Balls ISWWNited (Intrapate HWND); /// Set the focus on the previous example of the specified program. Public Static Zero SetFocusToPreviousInstance (string windowcasting) {// Find previous examples of this program. IntPtr hWnd = FindWindow (blank, window caption); // If the previous example of this program was found ... if (hWnd! = Null) {// Is it displaying a popup window? IntPtr hPopupWnd = GetLastActivePopup (hWnd); // If so, set the focus on the popup window otherwise focus on the main window of the program // If (hPopupWnd! = Null & amp; amp; enabled; (hPopupWnd); {hWnd = hPopupWnd; } Setanged Wando (HWND); // If the program has been reduced, restore it. If (ISINCOAC (HWND)) {Shawwondo (HWND, SWYSTTAR); }}}}}

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
