Can a Windows dll retrieve its own filename?
提问by Blorgbeard is out
A Windows exe file has access to the command string which invoked it, including its path and filename. eg. C:\MyApp\MyApp.exe --help.
Windows exe 文件可以访问调用它的命令字符串，包括其路径和文件名。例如。C:\MyApp\MyApp.exe --help.
But this is not so for a dll invoked via LoadLibrary. Does anyone know of a way for a dll to find out what its path and filename is?
但是对于通过LoadLibrary. 有谁知道 dll 找出它的路径和文件名的方法？
Specifically I'm interested in a Delphi solution, but I suspect that the answer would be pretty much the same for any language.
具体来说，我对 Delphi 解决方案感兴趣，但我怀疑对于任何语言，答案都几乎相同。

I think you're looking for GetModuleFileName.
我认为您正在寻找 GetModuleFileName。

If you are working on a DLL and are interested in the filename of the
DLL rather than the filename of the application, then you can use this function:
}
function GetModuleName: string;
var
szFileName: array[0..MAX_PATH] of Char;
begin
FillChar(szFileName, SizeOf(szFileName), #0);
GetModuleFileName(hInstance, szFileName, MAX_PATH);
Result := szFileName;
end;
Untested though, been some time since I worked with Delphi :)
未经测试，自从我使用 Delphi 以来已经有一段时间了:)
