The following sample code shows how to set the object data for the object with an ID of WP_SAMPLE, to have the specified title and use the specified help panel:
HOBJECT hObj; BOOL rc; { hobj = WinQueryObject( "<WP_SAMPLE>" ); if (hObj != NULLHANDLE) { /* WinQueryObject of WP_SAMPLE was successful */ rc = WinSetObjectData(hObj, "TITLE="Sample Object; HELPPANEL=SAMPLEHELP_ID"); if (rc) { /* Object data is set */ } else { /* WinSetObjectData failed */ } } }
