SYNTAX
send_message(hwin, msg, wparam, lparam)
post_message(hwin, msg, wparam, lparam)
These advanced functions are for the purpose of sending standard Windows messages to C programs, and are therefore not relevant to programmers who develop only in Sculptor. They have no effect if executed on UNIX and Linux versions of Sculptor.
hwin |
The handle to a window returned by the Windows CreateWindow() function. The handle could be supplied in a file or in a shared memory segment. This value can be saved in an i4 field. |
MSG |
A Windows API message code. These are defined by Microsoft and have the prefix WM_. |
wparam |
An i2 value as required by the particular message code. |
lparam |
An i4 value as required by the particular message code. |
The return value from send_message() is an i4 value specifying the result of the message processing. It varies according to the message sent.
The return value from post_message() is non-zero if successful or zero if it fails. The function only fails if an argument is not valid. A precise error code is available in Windows.
See the documentation for these functions in the Windows API for more information.
