Answer 2

If I recall correctly you want to open an excel file and then auto launch xml editor?
A way is to add a option the the contect menu when rightclicking on the xls file.
Use register for this:
HKEY_CLASSES_ROOT.xls\shell\
create a key (Default) and value something like "Open excel and xml editor"
create a folder "command" and a key (Default) with value "path to your exe" "%L" in that folder.
Then in your app catch the param (which holds the xls)
and then do something like this:
system(<var holding the xls name>);
system(<path to xml editor>):

Answer 3

You could use ShellExecute. It will automatically start program which associated with certain extension, or you could select program manually.
