【问题描述】:
我不知道为什么我不能使用 LoadLibrary 加载我的 dll“接口”。加载依赖项时似乎失败了,但我不知道为什么。
代码如下:
AfxMessageBox(L"before load library");
HMODULE interfacDll = LoadLibrary(TEXT("C:\\QA\\Pcdlrn\\Win32\\Release\\INTERFAC.DLL"));
if (!interfacDll)
DWORD dw = GetLastError(); // returns 0xc1 (193)
AfxMessageBox(L"after load library");
这是 gflags (x86) 的加载程序快照的输出:

我应该提到我使用的是 64 位 Windows,但我所有的可执行代码都针对 x86 (c#) 或 win32 (c++)。
我该如何解决这个问题?
任何建议将不胜感激。 非常感谢。

【问题讨论】:
-
这样称呼
GetLastError()是没有意义的。仅在函数失败时检查GetLastError()。 -
LoadLibrary 不会返回
HINSTANCE,并且在调用 GetLastError 之前您不会检查它是否失败。如果首先满足两个条件,您只能使用 GetLastError:1) 函数必须在文档中明确说明您可以使用 GetLastError 检索错误详细信息,以及 2) 函数必须实际失败,或者没有相关或有意义的信息让 GetLastError 返回。 -
错误 193 是 ERROR_BAD_EXE_FORMAT,很可能意味着文件已损坏,或者它是您正在加载到 64 位进程的 32 位 DLL,反之亦然。
-
@markf78 “这是重现问题的示例代码。” 与此处要求的minimal reproducible example 相差甚远。
-
Dependency walker 甚至显示错误来源:Error: Modules with different CPU types were found
