I want to use a managed classs to modify a string. I send a string from VB.net into a managed c++.net class trhough a funciton call with the string parameter defined as "Sting* stringvar". I have tried numberous ways to modify this string after assigning it to another string variable in the function. Is there any way to do this. I know in VB.net I need to use the string builder class but how do I do it in a managed c++.nete class?
