How Can I Find the Default Browser?

just wondering how i could find the default browser in windows. im runnin xp home fyi.

thanks for any help in advance.

By doing some research, I found that the exe is pointed to by the following registry key:

HKEY_CLASSES_ROOT\http\shell\open\command\default

Searched:
default browser win32

Got the following link:

You can save some leg work by getting AssocQueryString to search the registry for you.

Code:

---

#include <windows.h>
#include <shlwapi.h>
#include <stdio.h>

#if defined (_MSC_VER)
#pragma comment(lib, "shlwapi.lib")
#elif defined (__LCC__)
#pragma lib<shlwapi.lib>
#endif

#define ARRAY_SIZE(arr) (sizeof(arr)/sizeof((arr)[0]))

int main(void)
{
        HRESULT hr;
        TCHAR szExe[MAX_PATH + 100];
        DWORD cchExe = ARRAY_SIZE(szExe);

        if (SUCCEEDED(hr = AssocQueryString(0, ASSOCSTR_EXECUTABLE,
                                            TEXT("http"), TEXT("open"), szExe, &cchExe)))
        {
                printf("Path to default browser is '%s'.\n", szExe);
        }
        else
        {
                printf("Failed with error 0x%08.8x.", hr);
        }

        getchar();
        return 0;
}

Note: In my version of Dev-C++/Mingw, there is an error in shlwapi.h that will cause this code to give incorrect results. Lines 60-63 are:

Code:

---

typedef enum {
    ASSOCSTR_COMMAND,
    ASSOCSTR_EXECUTABLE,
    ASSOCSTR_FRIENDLYDOCNAME,

---

instead of:

Code:

---

typedef enum {
    ASSOCSTR_COMMAND    = 1,
    ASSOCSTR_EXECUTABLE,
    ASSOCSTR_FRIENDLYDOCNAME,
