How to get the default web browser path from registry?

Hi,

I'm looking for a source code to find the path of default web browser from the windows registry.

And, I want to know how to change the current URL of the browser which has been already working.

If you know how to do this, please give an answer.

Thanks.

The following code

HKEY hKey;
LPCTSTR lpSubKey = _T("http\\shell\\open\\command");
RegOpenKeyEx(HKEY_CLASSES_ROOT, lpSubKey, 0L, KEY_ALL_ACCESS, &hKey);
char szValue[256];
DWORD dwSize = 256;
RegQueryValueEx(hKey, NULL, NULL, NULL, (LPBYTE)szValue, &dwSize);



will place the executable path of the default browser in szValue.

Achieving remote control of the browser is a huge subject and will depend upon which browser(s) you want to work with. In the case of Internet Explorer, I suggest you look up IWebBrowser2 in the MSDN documentation in order to get started.

HKEY hKey;

// use Command Prompt...regedit.... to view registry

Dude, it's been 12 years.

I agree with GCDEF.
