notecard read help needed

Hello everyone,

I have tried different times to read 2 or 3 lines from a notecard, by using some simple scripts and examples i found, but i can same it to get it working.

I need a kind a script that reads line one (name), 2 and 3, to see if that person is 'on the list' so to speak, anybody that could help me out.

I have some experiecence with scripting but not a lot

thanks

marc

You will have to use this function to get the number of lines the Notecard contains :
http://wiki.secondlife.com/wiki/LlGetNumberOfNotecardLines

Then get each line using this function :
http://wiki.secondlife.com/wiki/LlGetNotecardLine

Here's a small example :

integer nLines = llGetNumberOfNotecardLines("My Notecard") // has to be in the object's inventory
integer i;

for (i = 0; i < nLines; i++)
{
     string lText = llGetNotecardLine("My Notecard", i);
     llSay(0, "Line #" + (string)i + " : " + lText);
}

This script has to be in the same Object as the Notecard.
I hope that helped

The following is an example of how to read a notecard:
http://lslwiki.org/index.php/LlGetNotecardLine

The following has been modified from the preceding article to include declarations of the global variables:

string gName="the name of your notecard";
integer gLine;
integer gQueryID;
default { 

   state_entry() {
       gQueryID = llGetNotecardLine(gName, gLine);    // request first line
   }
   dataserver(key query_id, string data) {
       if (query_id == gQueryID) {
           if (data != EOF) {    // not at the end of the notecard
               llSay(0, (string)gLine+": "+data);    // output the line
               ++gLine;                // increase line count
               gQueryID = llGetNotecardLine(gName, gLine);    // request next line
           }
       }
   }
}

You need to compare the query_id with gQueryID because the dataserver is responsible for returning all kinds of data, so the query_id is used to correlate the dataserver's response with your query.

True but he only needs this if you're doing other dataserver things. If you're only using it to read notecards, don't bother with the overhead of remembering & checking it.

To Mechant Boucher.. Uhh.. Might want to test your script out some more..

string gName="test";
integer gLine;
integer gQueryID;
default {

state_entry() {
gQueryID = llGetNotecardLine(gName, gLine); // request first line
}
dataserver(key query_id, string data) {
if (query_id == gQueryID) {
if (data != EOF) { // not at the end of the notecard
llSay(0, (string)gLine+": "+data); // output the line
++gLine; // increase line count
gQueryID = llGetNotecardLine(gName, gLine); // request next line
}
}
}
}

this script is given me a type mismatch error, by looking to other scripts i changed the
integer gQueryID; line into key gQueryID;
script is not giving me a error anymore, but also it does not say the lines in given in the notecard, it does nothing, the script is was working on, give me alway the oct code instead of the ascii text

where is my fault then ?? i don't understand at all
thanks for any help given

The correction you made is correct and it shoudl function.
Check that the script is still set to run as a compilation error will sometimes unset the check box.

Further investigation has shown this to have been a problem with the notecard.
If you use any characters above 127 then any llGetNotecardLine will return a null string.
The same problem will happen if your notecard has previously had any embedded objects, i.e. land marks or tetures, added to it.
