问题描述
使用消息窗口创建DLL时回头，我曾经有段时间正确地将wcex.lpszClassName加载为带引号的字符串.
一段时间以来，它一直是带引号的字符串wcex.lpszClassName =(LPCTSTR)"MyMessageWindow"，但是现在我将敏感"字符串编码为base64，并且再次加载wcex.lpszClassName会导致出现未创建的窗口的麻烦.
下面的结果导致一个空的wcex.lpszClassName，其中Dec()是Base64解码器，它接受std :: string并返回这种类型.
Dec("TXlNZXNzYWdlV2luZG93").c_str();
也是这样:
reinterpret_cast<(LPCTSTR)>(Dec("TXlNZXNzYWdlV2luZG93").c_str());
其他所有情况都会导致编译器类型转换错误. Dec()解码器
有效，并且确实返回"MyMessageWindow".
可能是什么问题?
:
Way back when creating my DLL with a message window I had the devil of a time properly loading the wcex.lpszClassName with anything but a quoted string.
It''s been a quoted string wcex.lpszClassName = (LPCTSTR)"MyMessageWindow" for some time but now I am encoding "sensitive" strings to base64 and loading wcex.lpszClassName is trouble again resulting in an uncreated window.
The following results in a empty wcex.lpszClassName, Where Dec() is the Base64 decoder that accepts std::string and returns such a type as well.
Dec("TXlNZXNzYWdlV2luZG93").c_str();
So does this:
reinterpret_cast<(LPCTSTR)>(Dec("TXlNZXNzYWdlV2luZG93").c_str());
Everything else causes a compiler type conversion error. The Dec() decoder
works and is indeed returning "MyMessageWindow".
What might be wrong?

推荐答案
std::string sClass = Dec("TXlNZXNzYWdlV2luZG93");
wcex.lpszClassName = sClass.c_str();
RegisterClassEx( &wcex );
