Re: How to use this class Chandrasekharan P6-Jul-09 19:40 Chandrasekharan P 6-Jul-09 19:40  you can do the following, 1. Add the class in to your solution explorer 2. Put the .h file in the program folder. 3. #include "SpreadSheet.h" where you want to call it 4. Create an instance of the class where you want to access it something like CSpreadSheet SpreadSheet; Use the instance to call the functions from the class. Hope it helps Re: How to use this class Davitor6-Jul-09 19:59 Davitor 6-Jul-09 19:59  thanks for reply. When i use these step 1. Add the class in to your solution explorer 2. Put the .h file in the program folder. 3. #include "SpreadSheet.h" where you want to call it then i am getting error fatal error C1083: Cannot open include file: 'SpreadSheet.h': No such file or directory so where i did wrong. Re: How to use this class Chandrasekharan P6-Jul-09 20:05 Chandrasekharan P 6-Jul-09 20:05  Use #include "CSpreadSheet.h" It should work.

The problem is the following. i have a class that i want to export, there are two private variables in the class, one of them is a struct. the variables are initialized in the constructor. In my ap, i created a object of my class and then delete it. Looks pretty straight forward, however, when deleting the object i get a error message "Debug Error". If i don't initialize the variables, delete is ok. if i memset the struct variable,i get a "scaler deleting destructor" error. Anyone got any idea why the dll behaves like this? ----------------------------------------AP------------------------------------ CIPCamDll *a = new CIPCamDll(); delete a; ---------------------------------------.h-------------------------------------- #ifdef IPCAMDLL_EXPORTS #define IPCAMDLL_API __declspec(dllexport) #else #define IPCAMDLL_API __declspec(dllimport) #endif typedef struct s { int abcd; }s; class IPCAMDLL_API CIPCamDll { public: CIPCamDll(void); CIPCamDll(char* para_address); ~CIPCamDll(void); private: int session_id; s m_t; }; -------------------------------------------------------------------------------- --------------------------.cpp--------------------------------------------------- CIPCamDll::CIPCamDll() { session_id = 13; return; } CIPCamDll::CIPCamDll(char* para_address) { return; } CIPCamDll::~CIPCamDll() { return; } ------------------------------------------------.cpp------------------------------- Re: problem in deleting dll class object.(scalar deleting destructor) CPallini6-Jul-09 20:58 CPallini 6-Jul-09 20:58  Where is the memset?

And i dont think you can create the windows GUI directly with a VGA using tc3.0 Windows actually works on wrapper code written on VC++ over the lower layer driver and C++ code. Yes you can create those but it will take a lot of effort. i.e you have a write wrapper What does this mean? FISH7866-Jul-09 15:16 FISH786 6-Jul-09 15:16  What does this message mean in a debug mode?

Re: What does this mean? FISH7866-Jul-09 19:20 FISH786 6-Jul-09 19:20  Yes I did. Re: What does this mean? Adam Roderick J6-Jul-09 19:46 Adam Roderick J 6-Jul-09 19:46  Use of invalid pointer. Pointer which is deleted most probably so once you delete a pointer intialize it to zero.
