.net - How to use the mutex code in a C# program? -


I have gone through the code of mutex, but this is giving me errors:

Public override disposal (bool disposing); There is no suitable method for disposal

This component is being started on startup, so I have commented on that part, but the main error I am facing is the Design View Part Is on:

Designer code can not be processed on line 26: throw new NotImplementedException; The code is generated by the code designer within the 'InitializeComponent' and should not be manually modified. Please remove any changes and try to open the designer again.

I can not see form.cs [design] how can I fix it?

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 second instance of // is running, then the Mutex constructor will block, and then throw an exception if the other permission is closed. 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); If you are actually trying to override "settlement", the method is a thing of the cover - this is  dissection ,  is not dissection . C # is case-sensitive. 
 
 For the rest of the problems, it is difficult to say because you have not really given enough information about what you are doing. If you want to start by telling us about your situation, it will help. What have you done, of course? Where does the mute come in?

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...
