1 I am using visual studio 2010 MFC to build a C++ program. My program calls a DLL that is not apart of the project and it accepts a char*. I have a function that gets a string in a format of LPCTSTR. I have been on google for about two hours now, and no solution found. How...

If your program uses the C++ standard classes (std namespace) then there is a solution using that. There is also a solution using the C runtime and anotehr using the Windows SDK.Wednesday, April 29, 2015 4:32 AMWhat are the differences between these two function CA2W and A2W?
it is a typedef for a const char *. In C, arrays decay into pointers to their first elements, so a char[] decays into a char*. Finally, any type of "pointer to T" (for any type T) can be implicitly converted into a "pointer to const T". Thus, combining these three facts, we...
C表示是一个常量 T表示Win32环境中有一个_T宏 STR表示一个字符串 所以LPCTSTR就是一个指向const对象的指针 2.常量字符串ansi和unicode的区分是由宏_T来决定的。但是用_T("abcd")时, 字符串"abcd"就会根据编译时是否定是_UNICODE来决定是char* 还是 wchar_t*。
在C++中,LPCTSTR是一个宏定义,代表一个指向以零终止的字符串的长指针。它是用于Windows平台API调用中的字符串类型,可以是char或wchar_t类型的指针,具体取决于是否定义了_UNICODE。 在C语言及其Windows编程应用中,LPCTSTR是一个经常遇到的数据类型,具有特定的含义和应用,本文将详细解释LPCTSTR的定义、用途及如何在实际应...
C表示是一个常量,const。 LPTSTR: 如果定义了UNICODE宏则LPTSTR被定义为LPWSTR。typedef LPTSTR LPWSTR; 否则LPTSTR被定义为LPSTR。 typedef LPTSTR LPSTR; 下面列出一些常用的typedefs: 类型MBCS Unicode WCHAR wchar_t wchar_t LPSTR char* char* LPCSTR const char* const char* ...

C就是const,常量(就是常量指针)STR,代表string,字符串的意思 T,应该是_T(),一个宏,比如_T("this is a string"),它和"this is a string"应该同一个作用,只是在移植到不同的系统上的时候兼顾程序的正确性。一般来说,用后者就可以完全满足一般电脑的要求。可以根据不同的str,进行强制...
