Question

我使用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();

我使用带有SSD的核心i7，这需要8秒钟才能显示文件。当我查看调试输出窗口时，

如何阻止GetOpenFilename加载DLL，如directx，git，tortoise git，groove，onedrive。有这么多，他们需要很长时间的加载，并不需要查看一堆文件名。

我正在寻找的真正答案是Slow loading of symbols during call to CoCreateInstance in VS 2012

基本上在工具/选项/调试/符号中排除加载dll 查找所有说无法找到或打开pdb文件的dll并将其添加到列表中
