Size limit for CC's?

[Jan Hoelterling]

I have a single CC called XPControls.CC containing custom classes for every
stock form object class. Each of these classes may have additional methods,
for example, I added an "enable" and "disable" method to every object
(rather than setting enabled = true/false). My main purpose is to control
visual behaviour in one place

When adding a single line today, I started getting unexplicable "variable
THIS not defined" pointing to:
CLASS XPToolbtn(oParent) of XPImage(oParent) custom
needless to say, oParent is a valid object reference.

As soon as I remove the line, everything works ok again. The offending line
is in my "enable" method for a grid:
function enable
this.enabled = true
this.colornormal = "WindowText/Window"
this.colorhighlight = "Windowtext/0xFFFFCC" ** This line causes the
problem
return

I then tried to remove a rarely used class (XPShape) from this CC, and I was
able to add the line
this.colorhighlight = "Windowtext/0xFFFFCC"
again, without any problems.

So, it seems to me that I must have somehow exceeded some size limit within
this CC. Why doesn't the compiler produce some error message rather than
causing problems in the execution later, with the error pointing to another
piece of code? For the compiler to produce code that looses "THIS" seems
pretty crucial.

Thanks in advance for your help.

Just wondering how big this file is - how many bytes, how many lines?

The file is 73340 bytes, which includes ample comments.

Including all comments, there are 2498 lines (which doesn't seem that much,
I definitely have files larger than that)

Executable lines (from the compiler) are 1827

Jan,

How many classes and how many methods do they have?

[Jan Hoelterling]

The file has 53 classes and 97 functions (accross all classes).

Jan,

OK, that's not a terribly large number.

[Jan Hoelterling]

The max line length is 1024, if I am not mistaken - and I am nowhere near
that anywhere.

Thanks for the suggestion, though.

HI Jan,

Sounds like there is a line some where that exceeds the max line. Check to
see if you do not have extremely long lines, especially those with the
continuation character. Cant remember what the limit is for a line in dbase

Can you simulate this error by removing your endclass statement ?

If, as I suspect, the answer is yes then the string passed for compiling is
being truncated at some stage

..... as you suspected.

I will give that a try

Without knowing the size of your file. its difficult to say. Once sure way
of testing this theory is to remove anotherline or two rather than a whole
class somewhere else in the cc. Most of the times this error is indicative
of a line size limitation.

Please see my reply to Bruce - the file really isn't that big.

Have you tried a different piece of code in this line position? Perhaps
this.gridLineWidth = 2
How about a different colour, like "white/red"?

Are there any LOOP statements in your code that control passes through
when you run the offending process?
