Re: Multiple selection causing application crash

Jean:

It was a call to the command SCI_GETSELTEXT() that I did not suspect to 
occur in a piece of code executed every 500 ms to update a value in the 
app's status bar.
I could not tell why this command crashed when called with multiple 
selection. Could it be related to the buffer size? I can post code if you 
wish.


   A too-small buffer will overflow and potentially cause trouble. The size 
required should be calculated first by calling SCI_GETSELTEXT with a NULL 
argument, then a new buffer allocated of the correct size which is then 
used for getting the actual value. There may be a +1 that is needed for the 
NUL byte terminator - this was changed at some point but allocating too 
much is safer.
