Hi All,

Our project is build using VC++(MFC) and few files have structures declared, few arrays of integers and char's and they are initialized statically. We have few static member variables initialized with data as below,
char* class::m_psz[] = {
TYPE_20 class::m_Defaults[] = {

And have few typedefs as below,
typedef unsigned char TYPE_20[20];

My requirement is to use Protocol Buffer concept and achieve the above. So How can i write the *.proto file (or the schema) to declare the static array of integers and initialize values to it. And finally i need to generate the *.cs (cshar file) out of it.

Below are my Basic knowladge on PB:
1) I created the classes, used "optional", "repeated" concepts.
2) created the code to declare 2d array.
3) how do I initialize the array at declaration time as it is done in C++?
Below is code of PB schema for 2d array without initialization(at static time)

repeated DefaultsForTYPE_20 m_DefaultsForTYPE_20 = 1;
message DefaultsForTYPE_20{
optional bytes m_DefaultsForTYPE_20 = 1;
but how can i initialize it here?

Please provide me your suggestions.

Thanks in Advance.

your TYPE_20 is some memory with a char array of 20 chars. So you access it this way:

void setDefaults( int v)
for(int i = 0; i < sizeof(TYPE_20); i++ )
m_Defaults[i] = v;//indexed access to the buffer

It is better to initialize data at runtime by calling such function.

Please read the Pointers Usage in C++ and try some code to better understand the inner conecept of C++. It is worth the time by saving you a lot of headaches. ;-)
