Windows, C++ | Bing Backgrounds Getter
Get Bing Wallpaper. It's a program written by C++, it will automatically download and set wallpaper for you!
Wallpapers, Bing…
Have you ever tried to download wallpapers from www.bing.com? Have you ever dreamed of a fantastic background but feel bored with download wallpapers by hands! It’s a program written by C++, it will automatically download and set wallpaper for you!
How does it works
It will download a XML file contains the API of www.bing.com, and then, I use tinyxml to parse the file to obtain the full URL-path of the daily wallpaper. Finally, the wallpaper will be download and set as the background.
Details
Platform:
- Windows 7
- Visual Studio 2019(Preview)
- Old damn computer & sh*t mouse & dusty keyboard
What’s the local of the wallpaper? After Googling, I get this: “https://www.bing.com/HPImageArchive.aspx?format=xml&idx=0&n=1&mkt=en-US”. That’s important, the full URL is contained in this file. Take a look at the label <image><url></url></image>, it’s the part of the full path, just cat "www.bing.com" with it, you will obtain the full path.
So, we should download the XML and try to parse it. We require URLDownloadToFile() to download remote files:

string xml_url = "https://cn.bing.com/HPImageArchive.aspx?format=xml&idx=0&n=1";
size_t len = xml_url.length();
int nmlen = MultiByteToWideChar(CP_ACP, 0, xml_url.c_str(), len + 1, NULL, 0);
wchar_t* buffer = new wchar_t[nmlen];
MultiByteToWideChar(CP_ACP, 0, xml_url.c_str(), len + 1, buffer, nmlen);
HRESULT hr = URLDownloadToFile(NULL, buffer, _T("C:\\Program Files\\The0d0re C00per\\Bing Backgrouds\\XML\\INDEX.xml"), 0, NULL);
if (hr == S_OK)
{
cout << "Download XML -----------------> DONE" << endl;
get_pic_url();
}
else
{
std::cout << "Xml download failed!Please check whether the network connection is normal!" << std::endl;
MessageBoxA(NULL, "Xml download failed!Please check whether the network connection is normal!", "WARNING!", MB_OK);
}
Next, the program should know where <image><url></url></image> is and what’s in this label. I use tinyxml to make it (more about tinyxml).

if (doc.LoadFile(xmlFile))
{
cout << "Load file -----------------> DONE" << endl;

else
{

}
TiXmlElement* images = doc.RootElement();
TiXmlElement* image = images->FirstChildElement("image");
string WebPicturedomain = "http://www.bing.com";
string WebPictureUrl = "";
if (image != NULL)
WebPictureUrl = image->FirstChildElement("url")->GetText();
string WebPictureFullpath = WebPicturedomain + WebPictureUrl;
cout << "Today Wallpaper Url Successful analysis!" << std::endl;
cout << "The address is:" << std::endl;
cout << WebPictureFullpath << std::endl;
URLDownloadToFile() again to download the wallpaper…

Finally, it’s time to set wallpaper as the background!!! I wrote a function:
