If you want to get a system icon in your computer or network neighbor, you can have the following solutions. Scenary One Icon Extract Software From C: /Winnt/System32/Shell32.dll or C: /WinNT/EXPLORER.EXE and then adds to its own program (the path varies from the operating system and installation directory) The shortcomings of the method are that the system icons of different operating systems have some changes, such as the system icons of 2003 and 2000, if you extracted 2000 icons, applications can appear in 2003. awkward. Solution 2 is also extracted with the C: / WinNT / System32 / shell32 file, but this time is done using the registry and Windows function. The code is as follows: hicon ctestdlg :: getShellicon (int NINDEX) {Hicon Hicon = NULL; HKEY HKEYSHELLCI
// Open the registry, read the corresponding icon item IF (regopenkeyex (hkey_local_machine, "software // microsoft // windows // currentversion ////// shell i cons", 0, key_read, & hkeyshellicons) == error_success) {char szBuffer [MAX_PATH]; DWORD dwSize = MAX_PATH; char szIndex [4]; sprintf (szIndex, "% d", nIndex); if (RegQueryValueEx (hkeyShellIcons, szIndex, NULL, NULL, (LPBYTE) szBuffer, & dwSize) == ERROR_SUCCESS ) {CString strFile, strIndex; AfxExtractSubString (strFile, szBuffer, 0, ','); AfxExtractSubString (strIndex, szBuffer, 1, ','); ExtractIconEx (strFile, atoi (strIndex), NULL, & hIcon, 1);} RegcloseKey (HKEYSHELLICONS);} if (! HiCon) ExtracticOnex ("shell32.dll", nindex, null, & hic, 1); return hicon;} This method overcomes the first method to use unfained disadvantages but code quantity comparison Big. (Index Directory is listed in the last list) Solution 3 uses the shell function ShgetSpecialFolderLocation and ShgetFileinfo. Code is as follows: LPITEMIDLIST lpItemIDList; SHFILEINFO shinfo; SHGetSpecialFolderLocation (this-> m_hWnd, CSIDL_NETWORK, & lpItemIDList); SHGetFileInfo ((LPCTSTR) lpItemIDList, NULL, & shinfo, sizeof (shinfo), SHGFI_SYSICONINDEX | SHGFI_DISPLAYNAME | SHGFI_ICON | SHGFI_SMALLICON | SHGFI_PIDL); this time The icon and Hicon in Shinfo saves the value of the obtained Icon. This method is both flexible, and the amount of code is relatively small, recommended. The second parameter in the ShgetSpecialFolderLocation is the CSIDL value of the image you want to get.

For Example, The System folder may be "C: / Windows" on one system and "C: / Winnt" on another CSIDL values provide a unique system-independent way to identify these special folders The values supersede the use of environment variables for this purpose A... CSIDL is used in conjunction with one of four Shell functions, SHGetFolderLocation, SHGetFolderPath, SHGetSpecialFolderLocation, and SHGetSpecialFolderPath, to retrieve a special folder's pathname or item ID list (PIDL). If a special folder does not exist, you can force its creation by using The Following Special Csidl:
CSIDL_FLAG_CREATE
Version 5.0
. Combine this CSIDL with any of the CSIDLs listed below to force the creation of the associated folder.The remaining CSIDLs correspond to either file system folders or virtual folders. Where the CSIDL identifies a file system folder, a commonly used path is given as an EXAMPLE. Other paths May be used. Some csidls can be be mapped to an equivalent% Variablename% Environment Variable. Csidls Are More Reliable, However, and Should Be Used if Possible.
