HKEY hKey;
struct HKEY__*RootKey;
TCHAR *SubKey;
DWORD dwType=REG_SZ;
DWORD dwLength=256;
TCHAR *ValueName;
LPBYTE SetContent_S;
RootKey=HKEY_CURRENT_USER;
SubKey="Control Panel\\Desktop\\WindowMetrics";
char content[256];
ValueName="Shell Icon Size";
RegOpenKeyEx(RootKey,SubKey,0,KEY_READ,&hKey);
RegQueryValueEx(hKey,ValueName,NULL,&dwType,(unsigned char *)content,&dwLength);
RegCloseKey(hKey);
RootKey=HKEY_CURRENT_USER;
SubKey="Control Panel\\Desktop\\WindowMetrics";
ValueName="Shell Icon Size";
SetContent_S=LPBYTE("24");
RegOpenKeyEx(RootKey,SubKey,0,KEY_WRITE,&hKey);
RegSetValueEx(hKey,ValueName,NULL,REG_SZ,SetContent_S,CString(SetContent_S).GetLength());
RegCloseKey(hKey);
SendMessageTimeout(HWND_BROADCAST,WM_SETTINGCHANGE, SPI_SETNONCLIENTMETRICS,0,SMTO_ABORTIFHUNG,5000,NULL);
SetContent_S=LPBYTE(content);
RegOpenKeyEx(RootKey,SubKey,0,KEY_WRITE,&hKey);
RegSetValueEx(hKey,ValueName,NULL,REG_SZ,SetContent_S,CString(SetContent_S).GetLength());
RegCloseKey(hKey);
SendMessageTimeout(HWND_BROADCAST,WM_SETTINGCHANGE, SPI_SETNONCLIENTMETRICS,0,SMTO_ABORTIFHUNG,5000,NULL);
