LPSTR在MSDN英文解释:Pointer to a null-terminal string of 8-bit Windows(ANSI) characters.LPSTR在MSDN中文解释:'L'代表Long,'P'代表Pointer(指针),'STR'表示String。 CString转换成LPSTR 1.1 方法一: 1CString strFileName;2LPSTR lpStr =strFileName.GetBuffer();3strFileName.ReleaseBuffer(); 1.2 方法二...
CString、LPSTR、std::string、LPCSTR之间的转换 LPSTR WideChar2MBCS(constCString& strCS ) { constUINT wLen = strCS.GetLength() + 1; UINT aLen = WideCharToMultiByte(CP_ACP,0,strCS,wLen,NULL,0,NULL,NULL); LPSTR lpa =newchar[aLen]; WideCharToMultiByte(CP_ACP,0,strCS,wLen,lpa,aLen,NULL,NUL...
调用c_str()以从一个std::string获取一个const char *（LPCSTR）。一切都在名义上：LPSTR-指向字符串...
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、LPTSTR、LPWSTR等等，你按照上面的方法拆开看就很清楚。2. std::string。这是C++标准库中的字符串类。是C++语言标准的一部分。提供对字符串的封装。用起来还算...

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 ...

str.c_str()给您一个const char *，这是LPCSTR（常量STRing的长指针）-表示它是指向0终止字符串的...
其实从pdb文件大小就看出来了:CString 所要求的动态链接库比STL string大太多了。 二。执行效率 CString: int WINAPI WinMain(HINSTANCE hInstance,HINSTANCE,LPSTR lpCmdLine,int nShowCmd) { char* buf; buf=new char[128]; CString s; DWORD start,end; ...
