Note
This documentation is intended for .NET Framework developers who want to use the managed UI Automation classes defined in the xref:System.Windows.Automation namespace. For the latest information about UI Automation, see Windows Automation API: UI Automation.
This topic contains example code that demonstrates how to use Microsoft UI Automation to insert text into a single-line text box. An alternate method is provided for multi-line and rich text controls where UI Automation is not applicable. For comparison purposes, the example also demonstrates how to use Win32 methods to accomplish the same results.
The following example steps through a sequence of text controls in a target application. Each text control is tested to see if a xref:System.Windows.Automation.ValuePattern object can be obtained from it using the xref:System.Windows.Automation.AutomationElement.TryGetCurrentPattern%2A method. If the text control does support xref:System.Windows.Automation.ValuePattern, the xref:System.Windows.Automation.ValuePattern.SetValue%2A method is used to insert a user-defined string into the text control. Otherwise, the xref:System.Windows.Forms.SendKeys.SendWait%2A?displayProperty=nameWithType method is used.
