![]() Once you have your cursors in place, you can type as usual and your changes will apply to each cursor location. Ctrl+Alt+Up: Add a new cursor above your current one.Ctrl+Alt+Down: Add a new cursor below your current one.Alt+Click: Place a new cursor where you click.Here are the important shortcuts in Visual Studio Code (on Windows): Visual Studio Code is my go-to editor nowadays, and it comes with multiple cursor support out of the box. It sounds like more trouble than it’s worth, but once you learn the shortcuts, it becomes natural. Multiple cursors is exactly what it sounds like: it lets you place more than one cursor in your editor so you can edit multiple locations at the same time. Now I use it every day, and I keep finding new ways to speed up otherwise tedious tasks. I had seen it before when digging through editor settings, but I had never bothered to actually try it until recently. Today, I have shown a few interesting tricks on what you can do with the simple Mouse Cursor.Programming using multiple cursors had always been a mystery to me. With a combination of these functions, you will be able to constrain your mouse pointer, and then restore it. Me.Cursor = New Cursor()Ĭursor.Position = New Point(Me.Left, Me.Top)Ĭursor.Clip = New Rectangle(Me.Left, Me.Top, _ ' and set its clipping rectangle to the form. ' set the Current cursor, move the cursor's Position, Public Sub RestoreCursor(ByRef ThisForm As _ Private Shared Function ClipCursor(ByVal _ ![]() This means that it will be impossible to move the mouse pointer outside the form’s bounds. In the next example, I will show you how you can constrain a cursor to only the form’s borders. Shows the cursor Constraining a Cursor’s Position Private Shared Function ShowCursor(ByVal bShow _ All you need is the ShowCursor Function that is created in the following example: _ ![]() Hiding and showing the cursor is quite easy. Inside the click event for the button, I specify where the cursor is and call the CreateCursor function to set the new cursor. A filename is sent as a parameter, and, if the filename is not valid, an error will be thrown. The CreateCursor function creates a cursor with the help of the LoadCursorFromFile API function. Throw New ApplicationException("Could not _Īdd the following code behind a button’s click event: Private Sub Button2_Click(sender As Object, _įileName = Path.Combine(Application.StartupPath, _ "user32.dll" Alias "LoadCursorFromFileW" _Īdd the next Function: Private Shared Function CreateCursor(ByVal _ We need to make use of the specific methods inside the specific Windows DLL files to do some nice stuff with the Windows Cursor.Īdd the namespaces necessary for the Windows API as well as to be able to read files: Imports Īdd the LoadCursorFromFile API Function: Private Declare Unicode Function LoadCursorFromFile Lib _ The methods of the programs are locked away in these files, and these methods make your applications work. These files are dynamically linked with the Operating System to run the program associated with it. The Windows system, or any system for that matter, is made up of a bunch of files, called DLLs amongst others. Then, you get the functions that run in the background, which you usually do not have to care about: keeping track of memory usage, obtaining a list of running programs. You have to remember that, in running Windows, you are indirectly executing code exposed by the Windows Operating System.Ī simple action, such as opening a file, executes the desired functionality needed for the file to be run. Any good program exposes some sort of API that can be used in other applications. The term API means Application Programming Interface. This technology is known as the Windows API. A common way to add more cursors is with Ctrl+Alt+Down or Ctrl+Alt+Up that insert cursors below or above. Each cursor operates independently based on the context it sits in. You can add secondary cursors (rendered thinner) with Alt+Click. VS Code supports multiple cursors for fast simultaneous edits. The Windows APIīefore going into depth about the cursor object, I need to speak about some of the background technology used. Multiple selections (multi-cursor) in vs code. The cursor functions enable applications to create, load, display, animate, move, confine, and destroy cursors. When the user moves the mouse, the system moves the cursor accordingly. In the remainder of this overview, the term mouse refers to any pointing device. CursorsĪccording to MSDN, a cursor is a small picture whose location on the screen is controlled by a pointing device, such as a mouse, pen, or trackball. Today, I would like to talk about the Cursor object and how you can utilize it properly from your Visual Basic program.
