how can i change default gateway address programatically

[sohnadilwala]

Good day to all pros:

i am facing a scenario where i need to change the default
gateway address of my local computer which is part of a
LAN. I want to create a VB/VC++ program by which when i
want to change my Gateway address all i need to do is run
the program and press the button.

is there any API or any function which can be used to
change the default gateway address?

Please Help

Thanks in advance
