 # Create a multi-instance tool window
-You can program a tool window so that multiple instances of it can be open simultaneously. By default, tool windows can have only one instance open.  
-  
- When you use a multi-instance tool window, you can show several related sources of information at the same time. For example, you could put a multi-line <xref:System.Windows.Forms.TextBox> control in a multi-instance tool window so that several code snippets are simultaneously available during a programming session. Also, for example, you could put a <xref:System.Windows.Forms.DataGrid> control and a drop-down list box in a multi-instance tool window so that several real-time data sources can be tracked simultaneously.  
-  
-## Create a basic (single-instance) tool window  
-  
-1.  Create a project named **MultiInstanceToolWindow** using the VSIX template, and add a custom tool window item template named **MIToolWindow**.

-## Make a tool window multi-instance  
-  
-1.  Open the *MIToolWindowPackage.cs* file and find the `ProvideToolWindow` attribute. and the `MultiInstances=true` parameter, as shown in the following example:  
-  
-    ```csharp  
-    [PackageRegistration(UseManagedResourcesOnly = true)]  
-        [InstalledProductRegistration("#110", "#112", "1.0", IconResourceID = 400)] // Info on this package for Help/About  
-        [ProvideMenuResource("Menus.ctmenu", 1)]  
-        [ProvideToolWindow(typeof(MultiInstanceToolWindow.MIToolWindow), MultiInstances = true)]  
-        [Guid(MIToolWindowPackage.PackageGuidString)]  
-        public sealed class MIToolWindowPackage : Package  
-    {. . .}  
-    ```  
-  
-2.  In the *MIToolWindowCommand.cs* file, find the `ShowToolWindos()` method. In this method, call the <xref:Microsoft.VisualStudio.Shell.Package.FindToolWindow%2A> method and set its `create` flag to `false` so that it will iterate through existing tool window instances until an available `id` is found.  
-  
-3.  To create a tool window instance, call the <xref:Microsoft.VisualStudio.Shell.Package.FindToolWindow%2A> method and set its `id` to an available value and its `create` flag to `true`.  
-  
-     By default, the value of the `id` parameter of the <xref:Microsoft.VisualStudio.Shell.Package.FindToolWindow%2A> method is `0`. This value makes a single-instance tool window. For more than one instance to be hosted, every instance must have its own unique `id`.  
-  
-4.  Call the <xref:Microsoft.VisualStudio.Shell.Interop.IVsWindowFrame.Show%2A> method on the <xref:Microsoft.VisualStudio.Shell.Interop.IVsWindowFrame> object that is returned by the <xref:Microsoft.VisualStudio.Shell.ToolWindowPane.Frame%2A> property of the tool window instance.  
-  
-5.  By default, the `ShowToolWindow` method that is created by the tool window item template creates a single-instance tool window. The following example shows how to modify the `ShowToolWindow` method to create multiple instances.  
-  
-    ```csharp  
-    private void ShowToolWindow(object sender, EventArgs e)  
-    {  
-        for (int i = 0; i < 10; i++)  
-        {  
-            ToolWindowPane window = this.package.FindToolWindow(typeof(MIToolWindow), i, false);  
-            if (window == null)  
-            {  
-                // Create the window with the first free ID.   
-                window = (ToolWindowPane)this.package.FindToolWindow(typeof(MIToolWindow), i, true);  
-                if ((null == window) || (null == window.Frame))  
-                {  
-                    throw new NotSupportedException("Cannot create tool window");  
-                }  
-  
-            IVsWindowFrame windowFrame = (IVsWindowFrame)window.Frame;  
-            Microsoft.VisualStudio.ErrorHandler.ThrowOnFailure(windowFrame.Show());  
-            break;  
-            }  
-        }  
-    }  
-    ```
