User32.dll的TranslateMessage（）API引发exception。 当我尝试使用windbg命令中的！analyze -v来分析exception时，我得到以下信息。 任何人都可以帮助我解码错误

问题是固定的。 错误发生在SetWindowLongPtr（）中。 这是SetWindowLong（）的64位变量，虽然函数被改变了，但是它的值仍然被long变量捕获，改成LONG_PTR修复了这个问题。 现在地址不会被截断，相应的用户程序被调用。
感谢大家的帮助:)
像上面提到的其他人一样 – 首先要做的是获得正确的符号。
微软公开它的Windows二进制文件的公开符号。 这将更好地了解发生了什么问题。
现在，看看你已经共享的！分析输出和TranslateMessage的签名。
BOOL WINAPI TranslateMessage( _In_ const MSG *lpMsg );
我最好的猜测是你没有验证lpMsg是一个真正的输入。 你能粘贴输入传递？
一般来说，已经出现一段时间的经验法则公共API已经得到了很好的测试。 所以，如果出现问题，检查我们的程序是通过什么输入是一个好主意:)
