如果想得到windows中我的電腦或者近端分享等系統表徵圖可以有如下解決辦法。
方案一
用表徵圖提取軟體從c:/winnt/system32/SHELL32.dll或者C:/WINNT/Explorer.exe中提取出來然後加入到自己的程式中（路徑隨作業系統和安裝目錄不同而變化）這種方法的缺點是不同的作業系統的系統表徵圖有一些變化，比如說2003和2000的系統表徵圖就有很大變化，如果你提取的是2000的表徵圖，應用程式如果在2003下運行可能看起來有一些彆扭。
方案二
同樣是利用c:/winnt/system32/SHELL32檔案來提取，但是這次是利用註冊表和windows的函數來完成。代碼如下：
HICON CTestDlg::GetShellIcon(int nIndex)
{
HICON hIcon=NULL;
HKEY hkeyShellIcons;
//開啟註冊表，讀相應的表徵圖項目
if(RegOpenKeyEx(HKEY_LOCAL_MACHINE,"SOFTWARE//Microsoft//Windows//CurrentVersion//Explorer//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,&hIcon,1);
return hIcon;
}
這種方法克服了第一種方法使用不靈活的缺點但是代碼量比較大。（index目錄在最後列出）
方案三
利用shell函數SHGetSpecialFolderLocation和SHGetFileInfo。代碼如下：
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);
這時候shinfo中的icon和hicon儲存了得到的icon的值。
這種方法既有靈活性，代碼量也比較少，推薦使用。在SHGetSpecialFolderLocation中的第二個參數是想得到的圖片的CSIDL值。

【附表2：CSIDL Values】
A number of folders are used frequently by applications, but may not have the same name or location on any given system. 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 mapped to an equivalent %VariableName% environment variable. CSIDLs are more reliable, however, and should be used if possible.
-
CSIDL_ADMINTOOLS
-
Version 5.0. File system directory that is used to store administrative tools for an individual user. The Microsoft Management Console will save customized consoles to this directory, and it will roam with the user.
