<div>
the EnableDHCP flag is a registry REG_DWORD below 
 
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\{xxxxxxxx-yyyy-zzzz-aaaa-bbbbbbbbbbbb}\Parameters\Tcpip 
 
where xxxxxxxx-yyyy-zzzz-aaaa-bbbbbbbbbbbb is the GUID of the LAN connection. 
 
you find the GUID below 
 
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Network 
 
note, the GUID would not change as long as you don't add/remove network adapters or their connections.

Dear expert, 
 
I need to use Win APIs to set value for EnableDHCP flag. 
But it seems I can not find the API to do this. 
So, is there any API for doing this? Please help me to find this. 
 
Note: until now, I can use Win API to set value for IPAddress , DefaultGateway and SubnetMask. 
 
Regards.

C is a general-purpose, imperative computer programming language, supporting structured programming, lexical variable scope and recursion, while a static type system prevents many unintended operations. By design, C provides constructs that map efficiently to typical machine instructions, so it has found lasting use in applications that had formerly been coded in assembly language, including operating systems as well as various application software for computers ranging from supercomputers to embedded systems. It is distinct from C++ (which has its roots in C) and C#, and many later languages have borrowed directly or indirectly from C.

C++ is an intermediate-level general-purpose programming language, not to be confused with C or C#. It was developed as a set of extensions to the C programming language to improve type-safety and add support for automatic resource management, object-orientation, generic programming, and exception handling, among other features.

Visual Basic .NET (VB.NET) is an object-oriented programming language implemented on the .NET framework, but also supported on other platforms such as Mono and Silverlight. Microsoft launched VB.NET as the successor to the Visual Basic language. Though it is similar in syntax to  Visual Basic pre-2002, it is not the same technology,
