Get IP Address

[OhioJoe]

In VO I used the following to get the computer's IP address:

Code: Select all

_DLL FUNCTION GetIPAddress(cHost AS STRING) AS STRING PASCAL:VO28INET.GetIPAddress

Which of course created the following error after conversion to XSharp

Code: Select all

Unable to load DLL 'VO28INET': The specified module could not be found. (Exception from HRESULT: 0x8007007E)

Does anyone know of an XSharp equivalent ? I figured I'd ask first before cutting and pasting someone else's C# code

Thank you

Hi Joe,
you can find an anwer here:
https://stackoverflow.com/questions/132 ... name-to-ip
But you could instead add the VOInternetClasses.DLL to your application and use that.

Hi Joje,

in my X# app i use this:

LOCAL hostName:=System.Net.Dns.GetHostName() AS STRING
LOCAL cIP:= System.Net.Dns.GetHostByName(hostName).AddressList[1].ToString() AS STRING

Hi Juray,
the second line provokes here: warning VN3030: GetHostByName is obsoleted for this type, please use GetHostEntry instead. http://go.microsoft.com/fwlink/?linkid=14202

I tried to use this, and it works , only difference ist, for "ByName" i get an IP4, with "Entry" an IP 6 address back.

Hi Karl,

I used it in one of the first of my XSharp application. Despite the warning, the program worked OK, so I did not solve it

Karl,

> warning VN3030

Are you using Vulcan?

Robert,
ups - yes, silly me hasn't noticed - this test app was really old

Changed it to X#/VO, swapped references, added VOInternetClasses.dll, compiles fine, albeit with the corresponding XS0618 warning - and it fails at runtime, because it can't find the latter (V 2.6.0.0), even when it is copied into bin.
Why?

[OhioJoe]

The following function compiles without warnings.

Code: Select all

FUNCTION XGetIPAddress(  ) AS STRING STRICT 
	LOCAL cHostName := System.Net.Dns.gethostname() AS STRING
	LOCAL cIP       := System.Net.Dns.gethostbyname(cHostName).AddressList[1].ToString() AS STRING
	RETURN cIP    // returns  192.168 ....

Thanks, Juraj. And Wolfgang and Fabrice and Robert.

That AddressList member is an array, which means it could return several IP addresses. I tested it here and it returned only one. But perhaps a more complete solution would be to loop AddressList and potentially return several IPs.

This dll depends on VOWin32APILibrary.dll and XSHarp.code.dll and XSharp.RT.dll, have you included those as well?

Yes, i have. Even made a new X# runtime app, added VOSDK classes, Win32Api and VoInternet, copiles flawless, but fails, now with wrong format...
