修改软件的ico图片方法

VC++[MFC]

// 第一个参数是将要替换图标的exe文件路径，第二个参数是替换的ico文件路径
void ReplaceExeIco(LPCTSTR lpszApp, LPCTSTR lpszIco)
{
 try
 {
  CFile file;
  file.Open(lpszIco, CFile::modeRead);
  LONG lOffset = 0;
  DWORD dwSize = 0;
  DWORD dwBytes = 0;
  CONST BYTE bGroupIcoSize = 0x18;
  BYTE* lpGroupIco = new BYTE[bGroupIcoSize];
  memset(lpGroupIco, 0, bGroupIcoSize);
  file.Read(lpGroupIco, 0x06);
  file.Read(lpGroupIco+0x08, 0x0C);
  memcpy(&dwSize, lpGroupIco+0x10, sizeof(DWORD));
  file.Read(&lOffset, sizeof(lOffset));
  BYTE* lpRes = new BYTE[dwSize];
  memset(lpRes, 0, dwSize);
  file.Seek(lOffset, CFile::begin);
  file.Read(lpRes, dwSize);

HANDLE hApp = BeginUpdateResource(lpszApp, NULL);
  UpdateResource(hApp, RT_GROUP_ICON, MAKEINTRESOURCE(1), 0, lpGroupIco, bGroupIcoSize);
  UpdateResource(hApp, RT_ICON, MAKEINTRESOURCE(1), 0, lpRes, dwSize);

  EndUpdateResource(hApp, FALSE);

  delete[] lpRes;
  delete[] lpGroupIco;
  file.Close();
 }
 catch (...)
 {
 
 }
}

//调用方法很简单，例如下面这样就可以了

ReplaceExeIco(_T("F:\\11.exe"), _T("F:\\11.ico"));
