HI all

i want to use structure inside the class

The way i did is

C#

testStruct.h

class testStruct
{


public:  struct msvq_param {         /* Multistage VQ parameters */
             int num_stages;
             int *num_levels;
             int *num_bits;
             int dimension;
             int num_best;
             int *indices;
             char *fname_cb;
             double *cb;
         };

};

C#

and in thetestStruct.cpp
i create object of class

testStruct testStructObj;


where ever structure is used i apply   testStructObj.msvq_param

but its not working properly

kindly guide how to use structure inside header file in side the class

and then by creating its object i can use its any where by adding header file
in that .cpp file

plz Help

You probably want to allocate a member of that structure in your class, for example by:

class testStruct
{
public:  
    struct msvq_param {         /* Multistage VQ parameters */
             int num_stages;
             int *num_levels;
             int *num_bits;
             int dimension;
             int num_best;
             int *indices;
             char *fname_cb;
             double *cb;
         } m_param;
};

Then you can access that member by (example)

testStructObj.m_param.stages = ...

Or your just want to access the structure definition. Then you would have to write:

testStruct::msvq_param   myParam;

Solution 2

Quote:
testStructObj.msvq_param

or rather correctly

Quote:
testStructObj::msvq_param

is a way to access the declaration of msvq_param

To utilize this structure, you should have a variable for this structure, which you can have as a protected/private member of your class
