[Tamas Szekeres]

David,   Would you file a bug report (mapscript C#) with this issue and i will look into it as soon as possible.   Thanks,   Tamas   From: UMN MapServer Users List [mailto:[EMAIL PROTECTED] On Behalf Of David Lowther Sent: Thursday, July 13, 2006 6:13 PM To: MAPSERVER-USERS@LISTS.UMN.EDU Subject: [UMN_MAPSERVER-USERS] Mapscript CSharp (C#) Memory Leak?   Hello All,   I’ve been toying with the mapscript_csharp.dll in VS2005 and cannot even begin to tell you how thrilled I am to have it. Thanks SO much.   I’ve encountered what I think might be a memory leak.   The exception text that I get is below and the entire source code of the application is available at: http://www.coordinatesolutions.com/download/mapservertestvb.zip   I get the exception after choosing ID from the drop down and clicking the map 15 times (why 15, I have no idea). When running the code from VS2005 the exception occurs at different places.   Any ideas?   David Lowther    Coordinate Solutions, Inc. 501 N.E. 15th Street Oklahoma City, OK 73104 405.246.9396 (Voice) 405.227.0781 (Fax) www.coordinatesolutions.com   See the end of this message for details on invoking just-in-time (JIT) debugging instead of this dialog box.   ************** Exception Text ************** System.AccessViolationException: Attempted to read or write protected memory.
