show example

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

hresult getbrowserversion(lpdword pdwmajor, lpdword pdwminor)
{
    hinstance   hbrowser;

    if(isbadwriteptr(pdwmajor, sizeof(dword)) ||
       isbadwriteptr(pdwminor, sizeof(dword)))
           return e_invalidarg;

    *pdwmajor = 0;
    *pdwminor = 0;

    //load the dll.
    hbrowser = loadlibrary(text("shdocvw.dll"));
	
    if (hbrowser == null)
    {
       //error loading module -- fail as securely as possible
       return;
    }

    if(hbrowser)
    {
        hresult hr = s_ok;
        dllgetversionproc pdllgetversion;

        // you must get this function explicitly.
        pdllgetversion = (dllgetversionproc)getprocaddress(hbrowser, text("dllgetversion"));

        if(pdllgetversion)
        {
            dllversioninfo dvi;
            zeromemory(&dvi, sizeof(dvi));
            dvi.cbsize = sizeof(dvi);
			
            hr = (*pdllgetversion)(&dvi);

            if(succeeded(hr))
            {
                *pdwmajor = dvi.dwmajorversion;
                *pdwminor = dvi.dwminorversion;
            }
        }
        else
        {
            // if getprocaddress failed, there is a problem with the dll.
            hr = e_fail;
        }

        freelibrary(hbrowser);

        return hr;
    }

    return e_fail;
}

downloading a version of internet explorer for redistribution

the ieak enables the application developer to have complete control over the redistribution of internet explorer. in some cases, however, the minimal installation package may be sufficient for an application's needs.

to download a minimal installation of internet explorer for redistribution, perform the following steps:

1. run ie6setup.exe and select install minimal or customize your browser.
2. click advanced, select download only to download just the minimal components to your system, and click ok to exit the dialog box.
3. click next.
4. specify the location where the files should be downloaded. otherwise, the files will be downloaded to the windows update setup files folder.
5. select a platform for installation, either windows 98, microsoft windows nt? or windows 2000.

the files are then downloaded to the local computer in the directory specified in step 4.

the following command line will install the internet explorer 6 minimal installation package in quiet mode, suppressing prompts as files are extracted.

ie6setup.exe /q /m:0

for more information about other installation options, refer to the documentation provided with the ieak.
