1. passing from a const string to a non const one 2. passing from an ANSI/MBCS string to a generic TCHAR based one I think the safest way to do that is just using CA2T, as David already suggested. Giovanni Tuesday, October 19, 2010 6:51 AM Thanks it is ok..中文...

路径改成 char*后,将string类型转化为char*. 提示string类型直接赋值给char* 错误: error C2440: '=' : cannot convert from 'const char *' to 'char *' 更正方法: 将char* 定义为 const char* 即可. 代码: string imbagFilePath="G:\\WorkSpace\\FileOperation\\fluor1_AjaxOrange_078.imbag"; ...
你传入strcmp的第一个参数是char**类型，所以报错。在第一个参数前再加上*即可编译通过。
可以知道LPCSTR代表了const char *类型，它是一个指向以'\0'结尾的8位（单字节）ANSI字符数组的常量指针，而const wchar_t *类型是一个指向'\0'结尾的16位（双字节）Unicode字符数组的常量指针.在VS2013编译器中直接输入的字符串常量（如“abc”）默认是以const char *的格式（即ANSI编码）储存的...
确定赋值给变量a，a是int类型吗？你这个报错是把一个int类型值赋值给一个char *指针。
