$menuOpen.Image = ::Extract('shell32.dll', 4, $true) The MenuItem is then added as a DropDownItem under the ‘File’ Main menu item. Shortcut Keys are defined and the text added. The numeric is the icon number used to reference it. The icon is added using the IconExtractor. I then add the first (Top Level) ToolStripMenuItem, ‘File’, to the Main Menu Items list. ToolsStrip is the base class for MenuStrip and StatusStrip, see the Control Architecture document. To build the Menu I first add the ToolStrip then the MenuStrip control to the Main Form. I setup the Main Form defining the Menu and Icon and centering in the screen. Private static extern int ExtractIconEx(string sFile, int iIndex, out IntPtr piLargeVersion, out IntPtr piSmallVersion, int -TypeDefinition $code -ReferencedAssemblies System.Drawing Return Icon.FromHandle(largeIcon ? large : small) Public static Icon Extract(string file, int number, bool largeIcon)ĮxtractIconEx(file, number, out large, out small, 1) After loading the assembly, you have a new Method to extract icons from DLL’s called IconExtractor. Without a direct call from PowerShell, I used the below code comes from the PowerShell Forum in the TechNet Script Center ( ). The rest of the icons I pull out of shell32.dll, one of many Windows system files which contain icons. From this I used the Information icon on the About menu item. There are a few icons that can be used in the SystemIcon Class. $iconPS = ::ExtractAssociatedIcon((Get-Command powershell).Path) First, for the icon on the main form I used the embedded icon from the PowerShell executable calling the method. These can acquired in a variety of ways, three of which I used here. I use icons on the menu items, main form and the About form. The objects used in the main form are defined. The below image is FormsMenu running on a desktop with a High Contrast theme so show how the WinForm elements follow the OS desktop theme when setting EnableVisualStyles. All the controls used in the script will utilize the desktop theme.Īdd-Type -AssemblyName This setting allows the Form to use the colors, fonts and other visual elements that form an operating system theme. Net assemblies and set EnableVisualStyles. Also a toolbar with buttons representing menu options and a status bar on the bottom. This script presents a WinForms Form layout with standard features including a pull-down menu supporting sub-menus, shortcut keys and icons. But sometimes you need a Form laid out with the ‘Standard” Windows menu system. To use Menustrip in the form, we have to drag the Menustrip from the toolbox and drop it to the form.Most of the scripts I have written for this blog have custom interfaces for that script. Microsoft Visual Studio groups the MenuStrip Control in the toolbox under the Menus & Toolbars group. Adding Menu and Menu Items to MenuStrip Control Then we will provide some simple handler for it. In this example, we will create the above shown C# Windows Form with Menu and Menu items in the C# MenuStrip Control. For Example, in the above picture, we can see one such sub-Menu with two Menu items in it. If a Menu item is linked with one more Menu, then the resulting Menu is called as Sub-Menu. Menu items are hooked up to a command handler, and when the user clicks the Menu item, the corresponding handler gets called. Say for example in the above picture, the Exit and Just for Demo are Menu items. In the above example form we add only File Menu to it. The below screenshot shows our example:Ī Menu bar dot net calls it as a Menu strip can hold multiple Menus. Similarly, the ToolStrip control allows us to add one or more Tool Bar buttons in it. A menu strip allows us to add Menu and Menu allows us to add Menu Items. In this Example, we will explore the C# MenuStrip and ContextMenuStrip Controls.Īll the strip controls accommodate some other UI elements in it. Dot net has three great strip controls, namely MenuStrip, StatusStrip and ToolStrip. About this MenuStrip Control ExampleĪ Strip is a nearly thin slice of an object.
