FindResource不；尽管资源确实存在，但找不到资源

我的手指受伤了。我正在尝试使用WinApi（FindResource）从我的exe加载资源。我已经成功地使用WinApi创建了一个字符串资源，并通过PE explorer、resource Hacker和Hex Editor验证了它们的存在。

我不能通过FindResource找到它们。函数结束，返回一些指针并将LastError设置为0。但是指针b指向无效内存。我尝试用4种不同的方式导入FindResource，结果都是一样的（b1、b2、b3、b4表示每个声明的b）。我发现我需要先加载库，让FindResource找到"一些东西"（a1=a2是两个相同的模块句柄，加载后将精确地指向内存中exe的开头，只是用不同的函数获取）。

我认为a（a=a1=a2）和b必须位于相同的内存空间中（偏移到模块开始？）。但是b和a的差值总是一样的16568。在十六进制编辑器中，我看到我的字符串大约偏移8000，并且在每次创建资源后都会有所不同。我知道可能出了什么问题，但我不确定：

• MAKELANGID(0, 0)~我知道0和0代表中性，我在哪里读到可能有关于*.mui文件的内容
• 资源创造创造了破碎的资源？事实上，两个资源编辑器在显示我的资源时都没有问题
• 进口申报可能是错误的，但我已经尝试了很多可能性，这些都是最好的
• 资源需要打开/锁定/什么

如何成功找到资源？我的代码中有错误吗

我知道互联网上有很多关于FindResource的帖子，我读过很多，但没有一个能解决这个问题。
