How to merge teh lines of two text files?

[Tony Bansten]

Assume I have two text files with multiple (long) lines each.
Now I want to merge them insofar that duplicate parts are eliminated
and the remaining parts are merged. Say I have the following files:

---- file1.txt ----
a aaa
bbbb
cccc
dddd
-------------------

---- file2.txt ----
cccc
dddd
eee
ff fff
-------------------

Then the resulting file should look like:

---- result.txt ---
a aaa
bbbb
cccc
dddd
eee
ff fff
-------------------

How can I code this with VB?

Keep in mind that there can be various combinations.
E.g. file2.txt could contain only a subset of lines:

---- file2b.txt ---
bbbb
cccc
-------------------

Then the result would be the file1.txt

Or - next variant - lines of file2.txt could overlap in front of file1.txt like

---- file2c.txt ---
kkk kkk
zz zzzzzz
a aaa
bbbb
-------------------

Would result in a resultfile

---- result3.txt ----
kkk kkk
zz zzzzzz
a aaa
bbbb
cccc
dddd
---------------------

Again: How can I code such a merge textfiles utility?

The vbscript should later be callable from commandline like

mymergetool.vb file1.txt file2.txt >result.txt

Tony,

Please do direct vbscript questions to VB.Net while you set only a reply in

(Your question is not asking for VB net code even)

Thanks in advance
