VBScript Send Method
last modified April 9, 2025
The Send method in VBScript is part of the WScript.Shell object. It simulates keystrokes by sending them to the active window. This method is commonly used for automation tasks and interacting with applications. It can send individual keys or combinations with modifiers like Ctrl or Alt.
Send is powerful but requires careful use as it affects the active window. It’s often used with AppActivate to target specific windows. This tutorial covers Send with practical examples to demonstrate its usage in various scenarios.
Send Method Overview
The Send method takes a string parameter representing keystrokes to send. Special keys are represented by codes in curly braces (e.g., {ENTER}). The method sends keystrokes to the window that currently has focus. It’s available through the WScript.Shell object in VBScript.
Key features include support for modifier keys (Ctrl, Alt, Shift) and special keys. The method doesn’t wait for the target application to process the keys. Understanding Send helps create automation scripts for repetitive tasks.
Basic Keystroke Simulation
This example demonstrates the simplest use of Send to type text. It shows how to send basic alphanumeric characters to the active window. The script types “Hello World” followed by an Enter key press.
basic_send.vbs
Set WshShell = WScript.CreateObject(“WScript.Shell”) WshShell.Send “Hello World” WshShell.Send “{ENTER}”
Set WshShell = Nothing
The script creates a WScript.Shell object and calls Send twice. First it sends the text “Hello World”, then the Enter key. The {ENTER} special code represents the Enter key. This simulates typing and pressing Enter.
Using Modifier Keys
This example shows how to send key combinations with modifier keys like Ctrl and Alt. It demonstrates the syntax for combining modifiers with other keys. The script sends Ctrl+C (copy) and Alt+F4 (close window) commands.
modifier_keys.vbs
Set WshShell = WScript.CreateObject(“WScript.Shell”) WshShell.Send “^c” ’ Ctrl+C WScript.Sleep 1000 ’ Wait 1 second WshShell.Send “%{F4}” ’ Alt+F4
Set WshShell = Nothing
The script uses ^ for Ctrl and % for Alt in the key combinations. The sleep command adds a delay between actions. Special characters must be enclosed in braces. This shows how to automate common keyboard shortcuts in scripts.
Sending Special Keys
Send can simulate pressing special keys like function keys, arrows, or navigation keys. This example demonstrates sending various special keys. The script sends Tab, Arrow keys, and function keys to navigate interfaces.
special_keys.vbs
Set WshShell = WScript.CreateObject(“WScript.Shell”) WshShell.Send “{TAB}” WshShell.Send “{RIGHT}” WshShell.Send “{F5}” WshShell.Send “{PGDN}”
Set WshShell = Nothing
Each special key is enclosed in curly braces with its name. TAB moves focus, RIGHT moves cursor right, F5 refreshes, and PGDN scrolls down. This shows how to automate navigation without mouse interaction in applications.
Targeting Specific Applications
This example combines Send with AppActivate to target a specific application window. It demonstrates proper window targeting before sending keys. The script activates Notepad before sending text.
target_app.vbs
Set WshShell = WScript.CreateObject(“WScript.Shell”) WshShell.Run “notepad” WScript.Sleep 500 ’ Wait for Notepad to launch WshShell.AppActivate “Notepad” WshShell.Send “Automated text entry” WshShell.Send “{ENTER}Second line”
Set WshShell = Nothing
The script launches Notepad, waits briefly, then activates its window. After activation, it sends text and Enter key. AppActivate ensures keys go to the correct window. This pattern is essential for reliable automation.
Complex Automation Sequence
This example shows a more complex automation sequence using multiple Send calls with delays. It demonstrates typing, navigation, and key combinations in sequence. The script automates a simple data entry task.
complex_sequence.vbs
Set WshShell = WScript.CreateObject(“WScript.Shell”) WshShell.Run “notepad” WScript.Sleep 1000 WshShell.AppActivate “Notepad”
WshShell.Send “Name: John Doe{TAB}” WScript.Sleep 200 WshShell.Send “Age: 30{TAB}” WScript.Sleep 200 WshShell.Send “^s” ’ Ctrl+S to save WScript.Sleep 500 WshShell.Send “user_data.txt{ENTER}”
Set WshShell = Nothing
The script fills a form-like interface in Notepad with field navigation. It uses TAB to move between fields and includes delays for reliability. Finally, it saves the file with Ctrl+S. This shows realistic automation with timing considerations.
