Conditional Compilation

[Jeff_Stone]

Does Lianja allow for conditional compilation with #DEFINE, #IFDEF and #IFNDEF?

We've got some VFP code to display messages to users that will not work with Lianja. So, we're trying to alter our display function based on use of #IFNDEF #ELSE #ENDIF. We defined LIANJACODE as 1. This shows up in the console during as execution as 1 in response to ? LIANJACODE. When the display function code is called:

#IFNDEF LIANJACODE
if mssg = " "
chose597.FrmChose597.LProcessMsg.Visible = .f.
else
chose597.frmchose597.LProcessMsg.visible = .T.
chose597.frmchose597.LProcessMsg.caption = mssg
endif
#ELSE
xlabel = lianja.getelementbyID("Main597_Pg.Genl_Parms.lproc essmsg")
xlabel.caption = mssg
xlabel.refresh
#ENDIF

we get the following error message which shouldn't be compiled or executed:
Wed May 29 12:01:28 2013
**** Lianja error ****
chose597.FrmChose597.LProcessMsg.Visible = .f.
^
Unrecognized command

If conditional compilation is not possible, we'll code differently.

Lianja supports conditional compilation. How did you define LIANJACODE?

There are several other ways to conditionally execute code:

if varType( isLianja() ) = 'L'
// Lianja specific code
else
// VFP specific code
endif

What type of messages are you wanting to display to the user exactly? There is a lot of built-in functionality that does that.

Lianja.showMessage("Processing data please wait...", 200)
...
Lianja.hideMessage()

Hi Barry,

We defined LIANJACODE:
#DEFINE LIANJACODE 1

We knew how to work around Lianja if #DEFINE, #IFDEF, etc functionality did not exist in Lianja but just wanted to know Lianja also supported this functionality with #INCLUDE files.

Fwiw, one of our applications displays messages to users via a Status textbox. This particular application is very simple from a UI perspective but does a lot of number crunching on a million+ mortgages that take quite a bit of time. The Status messages allow the users to work on other things while the application is processing.

Regards,

Jeff
