Re: What is equivalent to SELF when a form object's "variable or expression" is an object attribute?

It’s not so much that the pointer is not needed, but that it isn’t available so we have to figure out other ways to work around that fact when pointers would be more useful and allow you to write less brittle code. Having to specify almost the same text for the name as for the expression, or

Re: What is equivalent to SELF when a form object's "variable or expression" is an object attribute?

This was annoying the first time I ran into it, but overall hasn’t really caused any serious problems for generic programming. If you name the object with the expression, you can use something like: Form[Object Get name(Object current)]:=x If you need to set properties on a form object

In the debugger, look at your “emp” entity. It will show you the fields *and* relations. Just use the name it shows for the relation, I.e. $text:=$emp.Text and then access fields on $text like any other entity, or you can access the related one field directly.

I am printing a listbox on a form which just has a detail section (i.e. Print Form). The listbox is printing, but variable sized according to the arrays, and I’d like fixed size with empty rows. There isn’t much documentation on printing listboxes, there’s no “Print variable frame” checkbox

Since noticing the 4D function "Is field number valid”, making it easy to detect deleted fields, I thought field numbers would not be reused. It turns out this is not the case. A bit of testing reveals that 4D does not even clear the data when deleting a field, and still references data by

There is likely a bit of overhead in LEP, plus the overhead of launching processes, which is going to add up when used in a loop like that. For this particular case, your fastest option is probably to build a C_OBJECT with the filenames as keys and the file paths as values, and in your loop
