【问题描述】：
我正在使用 GetOpenFilename 来获取一些文件名
const int BUFFER_SIZE = 8192;
char* filenames = new char[BUFFER_SIZE];
filenames[0] = 0;
OPENFILENAME ofn;
ZeroMemory(&ofn, sizeof(ofn));
ofn.lStructSize = sizeof(ofn);
ofn.hwndOwner = ::GetActiveWindow();
ofn.lpstrFile = filenames;
ofn.nMaxFile = BUFFER_SIZE;
ofn.lpstrFilter =
"Quotes\0*.json\0"
"All\0*.*\0";
ofn.lpstrCustomFilter = NULL;
ofn.nMaxCustFilter = 0;
ofn.nFilterIndex = 1;
ofn.lpstrFileTitle = NULL;
ofn.nMaxFileTitle = 0;
ofn.lpstrTitle = "Web File Import";
ofn.lpstrInitialDir = "T:\\WebPending";
ofn.Flags = OFN_ENABLESIZING | OFN_ALLOWMULTISELECT | OFN_EXPLORER | OFN_FILEMUSTEXIST | OFN_HIDEREADONLY | OFN_PATHMUSTEXIST | OFN_ENABLEHOOK;
ofn.lpstrDefExt = "json";
ofn.lpfnHook = DDWebImport::Hook;
bool rv = ::GetOpenFileName(&ofn);
// Check the error if you have copied this code to another dialog and it returns immediately without popping up a form
DWORD err = CommDlgExtendedError();
我使用的是带有 SSD 的 core i7，这需要 8 多秒才能显示文件。当我查看调试输出窗口时，

如何阻止 GetOpenFilename 加载 DLL，例如 directx、git、tortoise git、groove、onedrive。有这么多，它们需要很长时间才能加载，并且不是仅仅查看一堆文件名所必需的。
【问题讨论】：
-
您无法控制 shell 在调用函数时决定需要加载哪些 DLL。 DirectX、Git 和其他工具的加载很可能与对话框可以选择显示的缩略图预览或图标覆盖有关（特别是在 Tortoise Git 的情况下，如果它类似于 Tortoise SVN）。
-
郑重声明，我不是反对您的问题的人。我刚刚发表了评论。
-
是否可以只显示文件名而不显示任何图标？在一天结束时，我只对选择一堆文件感兴趣。它不必显示任何图标。
-
Windows 不知道 用户 将决定做什么。他们可以将视图更改为小/中/大图标、列表、详细信息或缩略图预览。
-
它很慢，因为你安装了所有这些外壳扩展和集成。如果你想加快速度，你需要停止这样做。
