link value

[knoware]

There is probably a very simple answer to this, but how do you pass a value using the link command??

Not sure what you want. There's a "setkey()" method.

#handle SETKEY(stringExpr$) - Set the link's event key to stringExpr$

If this isn't helpful, can you describe your problem in more detail?

If you mean pass a value to a sub, then see setkey() in wiki building blocks entry under 'Link'.

Hmmm!
Maybe I'm not understanding how to do this.!!
I have a list if items displayed on the screen in a table.
About 20 items per page and each has an item number and description and other stuff.
Each item has a link to [Add], [Chg], [Del] and a couple others. Depending on what row you click the link, I need to pass that information.
So for example if you click the [Del] link next to item number 20,
I need to pass item number 20 back.

I tried several things but I must have the wrong syntax.
How exactly do I do it???

Thanks for the help..

Does this snippet of code help?

link #del,"[del]",delIt
#del setkey(20)

wait

sub delIt key
print key
'code to delete entry
end sub

Check out the Rowindex variable at runbasic.wikispaces.com/Runtime+Variables, it might do what you want.

You can use one sub to handle variable link values:

    [tryagain]
    link #one, "One", linker
        #one setkey("One")
    html " "
    link #two, "Two", linker
        #two setkey("Two")
    html " "
    link #quit, "Quit", linker
        #quit setkey("All done!")
    print
    wait

    sub linker key$
        print key$
        if key$ = "#quit" then end
    end sub

I'd have three handler subs, one for each common link -- Add, Change, Del. Then get the rowIndex, convert it to a string, put it in setKey. In Del, you pick up the key$, convert back to an integer, and feed it into your Delete row command. Same basic approach in the Add and Change subs.

You say the list is in a table. Are you creating the table with HTML?

If you are creating the table with a Run BASIC "Table" statement, only one column in the table can contain links.

The RowID mentioned in other responses is valid for RB Table elements, but not for elements in a table you format yourself with HTML. If you are using a "Table" statement, there's a RowID example here:

runbasic.wikispaces.com/Table#tocTable8

I asked for the RowID during beta testing and I find it to be very handy... thanks, Carl!

If you are creating the table yourself with HTML and making multiple elements in a "row" into links, the SETKEY() mentioned in some responses will help.

Can you please post some code? It's nearly impossible to help, otherwise.

Borrowing from Jerry's lead... How about this?

global x$
Dim x$(3)
x$(0) = "Andy"
x$(1) = "Roxy"
x$(2) = "Kerovia"
x$(3) = "Aglaope"

[start]
Call Main

Sub Main
  cnt = 0

  html "<table style=""border: 1px solid; padding: 2px;""><tbody>"

  for y = 0 to 1
    html "<tr>"
    for z = 0 to 1
      html "<td style=""border: 1px solid; mardin: 2px; padding: 2px;"">"
      link #link, x$(cnt), ShowName
      #link setkey(x$(cnt))
      html "</td>"
      cnt = cnt + 1
    next z
    html "</tr>"
  next y

  html "</tbody></table>"
  wait
End Sub

Sub ShowName nam$
  cls
  print nam$
  Call Main
End Sub
