下面四个错误怎么更改?

error C2664: “FindFirstFileW”: 不能将参数 1 从“LPSTR”转换为“LPCWSTR”

       与指向的类型无关；转换要求 reinterpret_cast、C 样式转换或函数样式转换

error C2664: “strcmp”: 不能将参数 1 从“WCHAR [260]”转换为“const char *”

       与指向的类型无关；转换要求 reinterpret_cast、C 样式转换或函数样式转换

error C2664: “strcmp”: 不能将参数 1 从“WCHAR [260]”转换为“const char *”

error C2664: “strcat”: 不能将参数 2 从“WCHAR [260]”转换为“const char *”
