To start with include namespaces
Now declare these variables
Now declare win32 function ShowWindow
The above function accepts 2 parameters hWnd is handle of a window whose state we needs to be modified and nCmdShow contains integer value which denotes state. Here are the list of available states
Now the main problem is how to get handle of a particular window. Its simple
Process[] processRunning = Process.GetProcesses();
This will return array of all the processes. After this you can use foreach loop to iterate through each process in the array.
Note Remember that it will just Hide the notepad process and not kill it. You need to be killing all the notepad.exe's running in the background through task manager. If you even wish to kill the process use
inside the if block.
Code: CSharp
using System.Diagnostics; // For prcesss related information
using System.Runtime.InteropServices; // For DLL importing
Code: CSharp
private const int SW_HIDE = 0;
Code: CSharp
[DllImport("User32")]
private static extern int ShowWindow(int hwnd, int nCmdShow);
Code:
SW_HIDE 0 SW_SHOWNORMAL 1 SW_NORMAL 1 SW_SHOWMINIMIZED 2 SW_SHOWMAXIMIZED 3 SW_MAXIMIZE 3 SW_SHOWNOACTIVATE 4 SW_SHOW 5 SW_MINIMIZE 6 SW_SHOWMINNOACTIVE 7 SW_SHOWNA 8 SW_RESTORE 9 SW_SHOWDEFAULT 10 SW_FORCEMINIMIZE 11 SW_MAX 11
Process[] processRunning = Process.GetProcesses();
This will return array of all the processes. After this you can use foreach loop to iterate through each process in the array.
Code: CSharp
int hWnd;
Process[] processRunning = Process.GetProcesses();
foreach (Process pr in processRunning)
{
if (pr.ProcessName == "notepad")
{
hWnd = pr.MainWindowHandle.ToInt32();
ShowWindow(hWnd, SW_HIDE);
}
}
Code: CSharp
pr.Kill();
