CueProvider is a tiny class that lets you set a cue banner (the grey prompt text that automatically disappears when you begin to type) in a
How to use CueProvider
CueProvider is easy to use, and has just two methods - one to set a
TextBox's cue text, the other to clear it. To set the cue text, call
SetCue(); to clear it, call
ClearCue(). These calls are best placed in your form's
CueProvider.SetCue (theTextBox, theCueText);
How it works
CueProvider works by sending the
EM_SETCUEBANNER message. The message is sent using the
SendMessage() Win32 API. More information on the
EM_SETCUEBANNER message can be found on this MSDN page.
As you can see, there's nothing overly complicated in this class. I put
CueBanner together in a few minutes, and wanted to share it with the CodeProject community in the hope it could help give our desktop apps a bit of UI "polish".
