VC implementation of Bulk Delete the specified file method _c language

The example described in this article mainly realizes the deletion of a file at a specified location under a letter, which can be txt, doc, JPEG, and so on, as long as the selected format, and then define a good letter, you can delete all the specified types of files. Once again, please confirm before deleting, and cannot be recovered after deletion.
The following are the main core codes, and other code readers can add them themselves.

Shfileinfo Shinfo;
memset (&shinfo,0,sizeof (shfileinfo)); Himagelist himage = (himagelist) shgetfileinfo ("c:\\", 0,&shinfo, sizeof (shfileinfo), Shgfi_sysiconindex |
Shgfi_smallicon); 
M_imagelist.attach (Himage);
M_comboex.setimagelist (&m_imagelist);
M_comboex.resetcontent ();
Char pchdrives[128] = {0};
char* pchdrive; GetLogicalDriveStrings (sizeof (pchdrives), pchdrives);
Enumerate disk characters pchdrive = pchdrives;
int nitem = 0;
 while (*pchdrive) {Comboboxexitem CBI;
 CString Cstext; Cbi.mask = cbeif_image| Cbeif_indent|
   cbeif_overlay| cbeif_selectedimage|
 Cbeif_text; Shfileinfo Shinfo;
 Define file information int nicon; Shgetfileinfo (pchdrive, 0, &shinfo, sizeof (shinfo), shgfi_icon| Shgfi_smallicon);
 Get system file Icon Nicon = Shinfo.iicon;

 Cbi.iimage = Nicon;
 Cbi.iselectedimage = Nicon;
 Cbi.ioverlay = 0; 
 Cbi.iindent = (0 & 0x03); M_comboex.insertitem (&CBI); Inserting Data Nitem++;
 Pchdrive + = strlen (pchdrive) + 1; return TRUE; Return TRUE unless your set the focus to a control} void Cdeletedlg::onsyscommand (UINT NID, LPARAM LPARAM) {if (NID

  GetFileName (); int index = str.
  Reversefind ('. '); if (str. Right (str. GetLength ()-index) = = name) {DeleteFile (findfile.
  GetFilePath ()); } else if (FindFile.
 Isdots ()) {continue; else if (findfile. Isdirectory ())//If this is the directory {delfile (findfile). GetFilePath (), name);//Recursive lookup}} void Cdeletedlg::onbutdelete () {//Todo:add your control notification handler code
 Here CString Path,name;
 M_comboex.getwindowtext (path);
 M_exname.getwindowtext (name);/Get File extension delfile (path,name); MessageBox ("The specified type of file has been deleted!") ");
}

This eliminates the form part of the code, the VC development friends should be able to understand.
