Hi,

You can follow below steps to access the string field from "mwArray" structure:

• mwString GetFieldName(int index) : This method returns the string by passing the index of the string field in your strucutre
• Convert above "mwString" to character pointer like below :

 const char* strPtr = (const char*)mwStr

• Now convert above character pointer to string using "string" function in C++. For example

string fieldString(strPtr); // where strPtr is your character pointer

Now, you can perform the desired operations on created string.

Refer the below documentation link on "mwArray" for more information:

I hope this helps!
