孙鑫《vc++教程》代码在vs2005中无法运行
里面的源代码直接运行没有错误。。
但我把源代码复制。然后新建win32控制台程序-windows程序-空项目
确无法编译：

[解决办法]
代码在VC6中没问题.
因为它的代码没有按可编译为UNICODE版本的方式写,而VS2005默认是UNICODE编码的.所以所有使用到字串的地方都会出错.
方法1:修改VS2005的设置
方法2:修改代码.字串前加TEXT宏.如
hwnd=CreateWindow(TEXT( "Weixin2003 "),
TEXT( "北京维新科学技术培训中心 "),WS_OVERLAPPEDWINDOW,
0,0,600,400,NULL,NULL,hInstance,NULL);
WinMain改为_tWinMain等.
[解决办法]
选择你的工程－》属性－》常规－》设置为不使用unicode
