Question

除了用＆＃34; -silent＆＃34;打开时，我的代码应该会产生错误的错误消息。作为一个命令行选项，但由于某种原因它无论如何产生假消息，但是当我调试它时（我有一些代码注释掉它可以尝试）它表明lpCmdLine正在返回＆＃34 ; -silent＆＃34;但是当在if语句中进行比较时，无论如何都总是如此。这是完整的代码：

lpCmdLine是一个指针，"-silent"也是一个指向内存中某个位置的指针，该字符串存储在编译时。所以，如果你写

if (lpCmdLine != TEXT("-silent")) {...}

这实际上会比较指针，而不是他们指向的文字。

要比较文字，请使用

if (wsccmp(lpCmdLine, L"-silent") == 0)

lpCmdLine不与字符串进行比较
