如何阻止 GetOpen文件名加载 DLL

Question

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*.json"
   "All*.*";
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();

我正在使用带有SSD的Core i7，这需要8秒以上的时间来显示文件。 当我查看调试输出窗口时，

如何阻止 GetOpenFile name 加载 DLL，如 directx、git、turtoise git、groove、onedrive。 有这么多，它们需要很长时间加载，并且不需要仅查看一堆文件名。

Answer 1

我正在寻找的真正答案是在VS 2012中调用CoCreateInstance期间加载符号缓慢

基本上排除在工具/选项/调试/符号中的加载中 dll查找所有显示找不到或打开 pdb 文件的 dll 并将它们添加到列表中
