I seem to be having a problem with TEUpdate. When I call TEUpdate with all of the required parameters, nothing happens. According to Macintosh Revealed (okay, not the authoritative source but that's what I've got), a TEUpdate should automatically do a TECalText and then update my text fields. Well after doing this nothing happens. Something else wierd. I set the teLength field of my edit record to the length of the text in the hText field, but both TECalText and TEUpdate set thee teLength field back to the size of the data area pointed to by the Handle which contains the text hText is pointing to! Because of this all of my scrolling calculations are off because every update resets the text length field! Can't calculate how much to scroll when this happens! Actually there is ONE way to get TEUpdate to work. I call TECaltext explicitly before doing the update, but this has the same problem with reseting the length field. TECalText munges it as badly as TEUpdate. Anyone with wizard experience and the TE package? This one is really difficult to handle. :-) Get it? "Handle."

Don't ever do this. TE guarantees that (**te).teLength == GetHandleSize((**te).hText). You should NEVER explicitly change (**te).teLength Also, TEUpdate always works just fine. I use it all the time, including to print (by doing TEUpdates at TEs that have been redirected to point to the printer's grafPort.) -- -- David Phillip Oster - At least the government doesn't make death worse. -- oster@well.sf.ca.us = {backbone}!well!oster

You should NEVER explicitly change (**te).teLength > This is simply not true. IM states very clearly that one may modify the teLength and hText fields. The catch is that you *must* call TECalText() before performing any further operations with the TEHandle. There is a one sentence indication on IM Vol I page 378. There is the reference to TECalText() on page 382. Set the two fields in question, then call TECalText(), then InvalRect(), then TEUpdate() and things should work. tim. ------------------------------------------------------------- Tim Endres | time@ice.com ICE Engineering | uupsi!ice.com!time 8840 Main Street | Whitmore Lake MI. 48189 | (313) 449 8288
