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 StringToW
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...
LPCTSTR is just a typedef that changes to LPCSTR if you don't #define UNICODE, or it could be LPCWSTR if you #define UNICODE. My first guess here is that you have never heard about this before, and I'll tell you what I always tell people trying to program for Windows: Understand how...

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...

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 ...
// For the `const char*` data type (`LPCSTR`); *restr = SysAllocStringByteLen(stlstr.c_str(), stlstr.size()); // More suitable for OLECHAR *restr = SysAllocString(stlwstr.c_str()); OLECHAR 取决于目标平台,但通常是 wchar_t。 根据您的代码,最短的代码片段可能只需要: *restr...
