c++ - Dealing with MFC form 'text' as char type or regular string type -

while modifying mfc form written others, visual studio 2012, encountered problem.

in form, there input box takes entire path of file. ex) c:\folder1\test_file.wav , in code, this->tb_path->text contains this.

first problem cannot find method deal this->tb_path->text char* or char type array use methods in string.h

in status quo, code uses

system:: string ^filename = this->tb_path->text + "_re";

to modify text, hampers various modifications of file path. how can solve problem?

try

system::string ^filename = gcnew system::string(this->tb_path->text + "_re");  

or may be

system::string ^filename = gcnew system::string(this->tb_path->text + _t("_re")); 

it seems me not doing required allocation in memory gcnew, garbage inside string uninitialized memory.
