Thanks Mike
While I was aware of the optional parameters feature of LC commands I have
never used it I so was unfamiliar with the syntax. The penny had never dropped
that the parameter list for a command is just an array, so evidently you can
actually send an array instead of a comma delimited list
Which means that you can send FindIndex a single parameter pKeyPairsA which is
an array with alternating colName,searchStr values
Setting up such an array is not particularly convenient for coding however. My
workaround had been to use a custom function hack
function myFindIndex pDataGrid, pKeyPairs
— pKeyPairs is a comma delimited list such as
“colname1,str1,colname2,str2,..”
replace comma with quote & comma & quote in pKeyPairs
put “dispatch FindIndex to” && pDataGrid && “with” && quote & pKeyPairs &
quote into tCommandStr
do tCommandstr
put the result into tFoundIndex
...
A much more elegant (if probably no faster) solution is
function myFindIndex pDataGrid, pKeyPairs
— pKeyPairs is a comma delimited list such as
“colname1,str1,colname2,str2,..”
set the columnDelimiter to comma
split pKeyPairs by column
dispatch “FindIndex" to pDataGrid with pKeyPairs
put the result into tFoundIndex
...
BTW, where did you find the source code for DataGrid handlers? I now see how
one could write a FindIndices function to return all indices rather than just
the first found … or even a general WHERE search :-)
