Auto Update %ProductVer%

[jassing]

Here's a little code snippet that I use in most of my installers.

Typically; you change the version # in SUF to reflect a new version of your installer.

What if you want this version to auto-update with your main application file?

Put this in an included LUA script file or global functions:

function SetupData.GetInternalFileVersion( cFileName )
	local tFiles = SetupData.GetFileList(ARCHIVE_LIST);
	local cVersion="0.0.0.0";

	if type(tFiles) == "table" then
		local x;
		for x = 1, Table.Count(tFiles) do
			 if String.CompareNoCase(tFiles[x].FileName, cFileName )==0 then
				cVersion = tFiles[x].FileVersion;
				break;
			end
		end
	end
	return cVersion;
end

Now in your "On startup" add this line:

SessionVar.Set("%ProductVer%", SetupData.GetInternalFileVersion("MYAPP.EXE") );

For large installs, this does add a noticable install; but for most; it's quick enough.

How can I do if i build a new version, for example from 1.0 to 2.0, in the ad or remove programs is a new link for the new version but a need to be autoupdated

The same approach that Josh gave here would work. However you should note that, if you reinstall the product using a different version number in the shortcut of the Control Panel, you will be creating a new shortcut instead of overwriting the existing one. For this reason it might be best to suppress the number completely - or you must perform an automatic uninstall before installing the other version. You should avoid stuff like this:

You can also use my FileVersion utility, or tools like Kinook's Visual Build to extract the version number and pass it to Setup Factory as a build constant.
