Tip: Understanding Intellisense operation

7 Attachment(s)

Did you know that if you check "Enable object naming conventions" in the App attributes intellisense for objects is displayed as you type "objectname."

The following prefixes to your variable names help the editor to display attributes and methods as you type.

Code:

section section column column field formitem page pagebuilder lbl label lab label chk checkbox col collection cbo combobox cmd commandbutton btn commandbutton cmg commandgroup cnt container cont container cb checkbox ctl control cad cursoradaptor ca cursoradaptor dte dataenvironment edt editbox eb editbox frm form frs formset grd grid grc column grh header hpl hyperlink img image lin line lst listbox lb listbox opt optionbutton opg optiongroup pag page pgf pageframe pg page sep separator shp shape spn spinner txt textbox tmp timer ti timer tbr toolbar web webview wv webview tb textbox db database rs recordset mb menubar mnu menu mi menuitem tre tree tri treeitem spl splitter sld slider prb progressbar dtxt datetextbox dttxt datetimetextbox pf pageframe dttb datetimetextbox dtb datetextbox

You can also declare the variable as a known classname to activate intellisense.

e.g.

Attachment 2569

If you use a variable which is an alias for a cursor intellisense looks it up and displayed the columns.

e.g.

Attachment 2570

If you declare a variable that is the id of a page intellisense is shown.

e.g.

Attachment 2571

Intellisense knows about database tables.

e.g.

Attachment 2573

You can press F1 on a command line of function( to display the documentation for that command or function.

Hi Barry,

Very cool!

VFP used something like that, extensible to custom classes, e,g.:

local loZip as myzip of myzipclass

In that instance,

loZip.

would display the attributes and methods of the class.

I would add that this feature came late in the versions, IIRC. One step at a time (and this is a good one). Not that I program classes nearly as much as I used to, but there are all these legacy VFP classes we will shortly be moving over to Lianja. :)

A great thing, if the function would also work in the console, it would be very helpful because you test a lot here. I can also imagine that it would do well in the debugger.
