Normally it's not possible to paste text from Windows clipboard to a textbox of a Java Applet. But it works to send single chars by WM_CHAR messages. That's what ClpSendChar does. When it starts it grabs the text from the Windows clipboard and then it sends the text char by char using WM_CHAR messages to the active text control. When you start ClpSendChar the cursor must be in the target. That's why you cannot start it thru the Windows Start menu because it doesn't activate the program that was active before. But you can create a link to ClpSendChar and define a hotkey there like Ctrl+Alt+V. Then you can use Ctrl+Alt+V to paste text from Clipboard to a Java Applet
