GET_URL_LIST with code?

rdrieder

I'm trying to get the list of IP addresses with the GET_URL_LIST function, but I'm not having any luck other than to get the number of URL's in the list. I'm able to use the ADD_URL_ENTRY function with no problem but I'm at a loss as to the correct coding to use. Any suggestions would be appreciated.

Did you create a structure IAW the format shown in the help file?

Show the code.

GET_URL_LIST with code?

Isn't the structure defined in the netlinx.axi file?
Here's the code...

DEFINE_DEVICE

dvMASTER = 0:0:0

dvTP	= 10001:1:0

(***********************************************************)
(*               VARIABLE DEFINITIONS GO BELOW             *)
(***********************************************************)
DEFINE_VARIABLE

	// FROM NETLINX.AXI FILE

//STRUCTURE URL_STRUCT
//{
//  CHAR     Flags;           // Connection Type (normally 1)
//  INTEGER  Port;            // TCP port (normally 1319)
//  CHAR     URL[128];        // string: URL or IP address
//  CHAR     User[20];        // optional account info for ICSPS Added v1.21
//  CHAR     Password[20];    // optional account info for ICSPS Added v1.21
//}

VOLATILE URL_STRUCT UrlList[24]

(***********************************************************)
(*                THE EVENTS GO BELOW                      *)
(***********************************************************)
DEFINE_EVENT

BUTTON_EVENT[dvTP,1]
{
	PUSH:
	{		
		LOCAL_VAR INTEGER i
		
		GET_URL_LIST(dvMASTER,UrlList,0) (* Get ALL URLs *)
		FOR(i=1;i<=LENGTH_ARRAY(UrlList);i++)
		{
			SEND_STRING 0,"UrlList[i].URL"
		}
	}
}

Use the return value of GET_URL_LIST as the FOR loop count instead of using the length (I don?t think it gets set by the function.)

Works, but with compile warnings...

Changed code, tried SINTEGER and SLONG for the LOCAL_VAR cnt, and get compile warnings, but the code does work now. Any ideas?

DEFINE_EVENT

BUTTON_EVENT[dvTP,1]
{
	PUSH:
	{		
		LOCAL_VAR INTEGER i
		LOCAL_VAR INTEGER cnt
		
		cnt = GET_URL_LIST(dvMASTER,UrlList,0) (* Get ALL URLs *)
		FOR(i=1;i<=cnt;i++)
		{
		        SEND_STRING 0,"UrlList[i].URL"
		}
	}
}

Try this:

BUTTON_EVENT[dvTP,1]
{
    PUSH:
    {       
        LOCAL_VAR INTEGER i
        LOCAL_VAR SLONG ret
	LOCAL_VAR INTEGER cnt
       
        ret = GET_URL_LIST(dvMASTER,UrlList,0) (* Get ALL URLs *)
	IF (ret > 0) { //if function does not return an error (-1 or -2) and there are URLs in the list
	   cnt = TYPE_CAST(ret) //thanks for the warning but we're ok
	   FOR(i=1;i<=cnt;i++)
	   {
		   SEND_STRING 0,"UrlList[i].URL"
	   }
	 }
    }
}

You don?t need local_vars unless they?re declared that way for debugging purposes.

rdrieder

Works with TYPE_CAST

Thanks Joe, LOCAL_VARS were used just for debugging. Appreciate your help.

Glad to help. Have fun.
