如何将char []打印到消息框？

Question

我想将str2打印到messagebox，但没有打印任何内容。这是代码..

    char str2[256];
    fstream file_op2("C:\\PROGRA~1\\executables\\path.txt",ios::in);
    file_op2.getline(str2, 256);
    file_op2.close();  

    CString mycustompath;
    mycustompath = str2;
    MessageBox(NULL,mycustompath.GetBuffer() , L"read custom path", MB_OK);

Answer 1

尝试：A printf type of MessageBox function which takes variable arguments
