A Multiple Document Interface (MDI) programs can display multiple child windows inside them. This is in contrast to single document interface (SDI) applications, which can manipulate only one document at a time. Visual Studio Environment is an example of Multiple Document Interface (MDI) and notepad is an example of an SDI application. MDI applications often have a Window menu item with submenus for switching between windows or documents. ![]() Create a new C# project, then you will get a default form Form. Then add two mnore forms in the project (Form. Form 3) . Create a Menu on your form and call these two forms on menu click event. Click here to see how to create a Menu on your form How to Menu Control C#. Killing Processes From a Windows Form Application in C#Introduction. This article provides a simple example of how to use the System. Diagnostics. Process library to display a list of running processes, and to select and kill processes by their process name and ID. It would not be a major trick to display additional information about the process using the same library or to kill processes by their ID or name alone rather than their name and ID but in this example, process names and IDs are used for display purposes and the purpose of killing a running process. Figure 1: Listing and Killing Processes by Process Name and IDGetting Started. There is a single solution included with this download, the solution contains a Win Forms project called . If you open the attached project into Visual Studio 2. Figure 2: Solution Explorer. Code: The Main Form. The main form contains all of the user interface elements necessary to display and update the list of currently running processes found on the user's machine. It also contains a button handler which will kill a process by the process name. You can also kill a process by its ID but in terms of readability, if the user is selecting the process, the process name is going to make a lot more sense to them than will the process ID. The class begins with the normal and default imports: using System; using System. Collections. Generic; using System. Component. Model; using System. Data; using System. Drawing; using System. Linq; using System. Text; using System. Windows. Forms; The constructor calls a method called . At the end of the function, a status message is updated to display the current number of found processes. Since you can have multiple processes with the same name, it was necessary to add in the ID along with the name in order to make some distinction between multiple instances of a single application, else, we would end up killing all running instances of the application which may or may not be desirable depending upon what you are doing. If you do want to kill off all running instances of an application, disregard the ID and kill all running processes with the same process name. In the kill button click event handler; we again loop through all of the running processes and we take the selected item from the process/ID list, and parse it into a string containing the process name and an integer value containing the ID. If the current process (in the loop) matches on both the process name and process ID, the process is killed. At the end, the handler calls the update method used to repopulate the listbox such that is displays the current list of active processes and their IDs.///< summary> /// Kill the process selected in the process name /// and ID listbox ///< /summary> ///< param name=. One could also kill all instances of a particular process by killing all processes that match on name without giving any consideration to the process ID. The approach shown allows for singling out specific instances of a process and killing it without taking down all other matching processes.
