如果程序不使用UNICODE字符集,我们可以直接将std::string的c_str()方法返回的const char*转换为LPCSTR。 2. 编写代码实现std::string到std::wstring的转换(如果需要) cpp #include <string> #include <windows.h> std::wstring StringToWString(const std::string& str) { int len = Mult...
简介:错误 不存在从 “std::string“ 到“LPCSTR“ 的适当转换函数 遇到这样的问题需要将std:string类型转为LPCSTR类型。 标准库的std::string转换成LPCSTR很简单:直接调用c_str()即可。例: std::string a="abc"; LPCSTR str = a.c_str(); 还有一种情况是wstring 标准库还有一个wstring,代表宽字符的string...
这是一个LPCSTR(指向常量string的长指针) --这意味着它是指向以0结尾的字符串的指针。W表示宽字符串(...
You need to use z.c_str() - and also you may need to use tstring rather than string (since you're using LPCTSTR rather than LPCSTR). Dave Thursday, March 22, 2012 8:40 AM On 22/03/2012 09:11, hardyz wrote: i have a string z="hi how are you"; and LPCTSTR xyz; now i wa...

I want to get a LPSTR out of a string that I have created - this is to be used in a "createprocess" function which apparently dosn't like to use LPCSTR. The code that I have looks like a long hand way of doing it. This does seem to work but is there a better way of doing ...

1. LPCTSTR 实际上就是字符串，不过是会根据当前的字符集进行自适应：如果是ANSI的话，LPCTSTR = const char* ，如果是Unicode的话，LPCTSTR = const wchar_t*。其实这是windows下的命名方式，你把它的名字拆开了看就很清晰：LP：长指针，C：const，T：自适应，STR：字符串。类似的还有LPCSTR、LPSTR...
