function SendMessage(const AMessage: TJwString; const ACaption: TJwString; const uType: DWORD; const ATimeOut: DWORD): DWORD;

Parameters	Description
const AMessage: TJwString	string that contains the message to be displayed.
const ACaption: TJwString	string that contains the dialog box title.
const uType: DWORD	Specifies the contents and behavior of the message box. This value is typically MB_OK. For a complete list of values, see the uType parameter of the MessageBox function.
const ATimeOut: DWORD	Specifies the time, in seconds, that the SendMessage function waits for the user's response. If the user does not respond within the time-out interval, the pResponse parameter returns IDTIMEOUT. If the Timeout parameter is zero, WTSSendMessage will wait indefinitely for the user to respond.

SendMessage returns the user's response, which can be one of the following values:

Value	Meaning
IDABORT	Abort button was selected.
IDCANCEL	Cancel button was selected.
IDIGNORE)	Ignore button was selected.
IDNO	No button was selected.
IDRETRY	Retry button was selected.
IDYES	Yes button was selected.
IDASYNC	The bWait parameter was FALSE, so the function returned without waiting for a response.
IDTIMEOUT	The bWait parameter was TRUE and the time-out interval elapsed.

If the function fails you can use GetLastError to get extended error information

Remarks If you don't need to wait for the user's response you can use the PostMessage function

The SendMessage function displays a message box on the client desktop.
