    Hi there!
    Can anyone tell me the way to handle array as data source for NtkTbrowse object?
    Any tutorials or sample code?
    Thanks Chris

    in my opinion, the arrayrdd support that comes with the NTKADORDD contribution is the best option.
    e.g.
     
// Create a new dbf in memory using dbCreate() 
   aStruct := { ;
                { "NAME"     , "C", 40, 0 } ,;
                { "ADDRESS"  , "C", 40, 0 } ,;
                { "BIRTHDAY" , "D",  8, 0 } ,;
                { "AGE"      , "N",  3, 0 }  ;
              }
   dbCreate( "arrtest.dbf", aStruct, "ARRAYRDD" )

// Open it and browse records
   USE arrtest.dbf VIA "ARRAYRDD" NEW ALIAS dataSrc
   @ nTop,nLeft TO nBottom,nRight CREATE BROWSE oB ;
                        WITH DBAREA dataSrc INTO hWnd

    Morning Wilson
    Thanks for the Tip - didn't even know this was possible!
    So I eagerly tried to create a quick TestApp with this code but got linkage errors when building the program.

    Oh, I forgot to mention: I didn't find arrayrdd.prg in C:\wntk4hrb\Contrib\AdoNtkRdd\ as you told me but in the C:\xharbour\source\rdd\usrrdd\rdds sub-dir. :wink:
