Hi I am facing this problem in Visual Studio 2005 using VB-2005 and native unmanaged c++ dll which in turn uses libxml2. * "Attempted to read or write protected memory. This is often an indication that other memory has been corrupted. "*
I will try to explain the problem in a simplistic approach as its difficult to paste the coding bits because its a bit elaborative out there. VB-2005 --> MyDLL.dll <-- libxml2 I am calling exported functions from MyDLL.dll into my VB application and all seems to be working fine until I started getting the above error under a certain condition. Say if all my exported functions are in a.cpp which I call, I have also declared certain global variables like int d_winnerModels; float d_Prob; xmlNodePtr gramCur; set<long> currentGrammarModels; . . . which gets populated during some initialisation calls to a.cpp In a file b.cpp I am using certain global variables using extern statement like, extern int d_winnerModels; extern float d_Prob; extern xmlNodePtr gramCur; extern set<long> currentGrammarModels; My other global variables like vectors, sets, integers etc seem to work fine but for the above libxml related variable (gramCur) I am getting the above error. Has anyone got a clue of what extra care needs to be taken or is it some complier optimisation issue for third part dll's. I am running everything in debug mode so I guess all optimisations are automatically switched off... Any help/ thought will be greatly appreciated Sid
