Hi

I have a requirement where I will need upto 150 N-Up dataObjects eg 1 - 150 columns to be available at runtime

so that I can switch to the appropriate DataObject based on a selection by the end user.

I know I could do this by Hand which I dont really want to do.

I could write a script / program to generate the DataObject syntax (based on an existing DataObject) for each one required and save in a file appropriately .

There may be a better way?

Does anyone know how ?

You may create the datawindows at runtime using datawindows Create function.

Thanks I presume you mean something like



String ls_dwsyn, ls_errors

ls_dwsyn = LibraryExport("c:\pb\dwTemp.pbl", &

    "d_emp", ExportDataWindow!)



 



//////MANIPULATE the syntax to achieve the desired N-UP's on dataobject​ with some type of



///// search and replace / insert of syntax



 ///// And then

dw_1.Create(ls_dwsyn, ls_errors)

There are many options, e.g. library export, store the syntax in the database or build it in your code.
