![]() If your application relies on consistent behavior regardless of the operating system, you can force the SendKeys class to use the new implementation by adding the following application setting to your app.config file. Additionally, when the SendKeys class uses the new implementation, the SendWait method will not wait for messages to be processed when they are sent to another process. As a result, the SendKeys class may behave differently on different operating systems. The SendKeys class tries to use the previous implementation first, and if that fails, uses the new implementation. The updated implementation is still susceptible to timing issues, but is slightly faster and may require changes to the workarounds. The SendKeys class is susceptible to timing issues, which some developers have had to work around. The enhanced security of Windows Vista (known as User Account Control or UAC) prevents the previous implementation from working as expected. NET Framework 3.0 to enable its use in applications that run on Windows Vista. The SendKeys class has been updated for the. To specify one of these characters, enclose it within braces ( means press H 10 times. The plus sign (+), caret (^), percent sign (%), tilde (~), and parentheses () have special meanings to SendKeys. To represent the letters A, B, and C, specify the parameter as "ABC". To represent more than one character, append each additional character to the one preceding it. For example, to represent the letter A, pass in the string "A" to the method. To specify a single keyboard character, use the character itself. To wait for any processes started by the keystroke, use SendWait.Įach key is represented by one or more characters. To send a keystroke to a class and immediately continue with the flow of your program, use Send. Use SendKeys to send keystrokes and keystroke combinations to the active application. ' Send the enter key since the tab stop of Button1 is 0, this Private Sub Form1_DoubleClick(ByVal sender As Object, _īyVal e As System.EventArgs) Handles MyBase.DoubleClick ' Use the SendKeys.Send method to raise the Button1 click event Private Sub Button1_Click(ByVal sender As System.Object, _īyVal e As System.EventArgs) Handles Button1.Click ' Clicking Button1 causes a message box to appear.

When the example is running, double-click the form to trigger the button's click event. The button control's TabIndex property should be set to 0. Ensure the click events are associated with their event-handling methods in this example. To run the example, paste the following code in a form called Form1 containing a button called Button1. The following code example demonstrates how to use the Send method. ![]()
