copied!<p>I'm developing an application in C++ for Windows 7, that sets up a TFTP server to communicate to an embedded device. The device is supposed to be connected directly to the Ethernet port, and it expects a TFTP server on 192.168.1.19 static address.</p> <p>To simplify user experience, I want the following scenario:</p> <ul> <li>present a list of all network connections registered in the system to the user (same list as in "Control Panel\Network and Internet\Network Connections")</li> <li>allow to choose one connection</li> <li>memorize its IPv4 configuration</li> <li>set IPv4 configuration to 192.168.1.19 and 255.255.255.0</li> <li>after TFTP job done, restore original IPv4 configuration</li> </ul> <p>The problem I encountered is a mix of the following:</p> <ul> <li>when no Ethernet cable plugged, neither of GetAdaptersInfo, GetInterfaceInfo, GetAdaptersAddresses list the connection I'm interested in;</li> <li>even if I get that connection, I'm not sure which API to use to set DHCP on/off, static IP, network mask.</li> <li>I tried using netsh, and it works fine, but I don't want to run it from my app, because I don't want to deal with non-English characters in the connection names.</li> </ul> <p>Suggestions welcome, Thanks!</p> <p>===== edit #1</p> <p>Tried WMI query "Select * From Win32_NetworkAdapter Where NetConnectionID = 'Local Area Connection'" -- no IP address in the feedback, although I can see it in the Control Panel connection properties.</p> <p>Queries involving Win32_NetworkConnection don't return anything at all.</p>
