I'll put this into the next build. Thanks!

I thought the mailing list had blocked my attachment. I just started to use the sc-net Modified event handler, and once in a while, it throws an error telling me that the unmanaged code has overflowed a buffer, and possibly corrupted some memory. I looked into the problem, and it appears to lie within code from ScintillaControl.cs: Specifically, I don't think all of the modification events supply a valid string pointer. Some of them *appear* (I do not know this for sure) to pass a pointer that points to garbage instead. After watching this for a bit, I noticed that the 0x400 (beforeinsert) event mask is the only one that seems to have a (valid) string attached to it!? If this is the case, then there needs to be some code added to test if that bit is indeed set, and then act accordingly.... ie: if(( scn.modificationType & (uint)Enums.ModificationFlags.beforedelete )>0 ) Modified( this, scn.position, scn.modificationType, System.Runtime.InteropServices.Marshal.PtrToStringAuto(scn.text), scn.length, scn.linesAdded, scn.line, scn.foldLevelNow,scn.foldLevelPrev ); else Modified( this, scn.position, scn.modificationType, null, scn.length, scn.linesAdded, scn.line, scn.foldLevelNow,scn.foldLevelPrev ); this should prevent that crash from happening, but it doesn't gurantee that the other variables are valid of course... -- Regards, Greg Dietsche http://www.gregd.org/ <http://www.gregd.org> GForce Programming: http://calc.gregd.org Detached Solutions: http://www.detachedsolutions.com -------------------------------------------------------------------------- ScintillaNET Mailing List: ScintillaNET@xxxxxxxxxxxxx To unsubscribe: Send an email to scintillanet-request@xxxxxxxxxxxxx and put "unsubscribe" (without the quotes) in the Subject line.
