I get a "stream does not exist" error.

I haven't tried running the code, but could it be that 'A_FILE' on the last line should be 'A_FILE$'?

I think Jay mentioned that once it's defined as a string then the dollar sign may be optional.

I'll try it though since that was the syntax method I used mostly during school.

** Nope. The software does the same even with the dollar sign.

** When using FILETYPE(...), is the value returned 1,0,-1?
I'm getting conflicting documentation.

To be honest it almost impossible to read formatted like that (are the semi-colons Blitz comments?).

What is the code actually meant to do?

Here's the edited code for better reading.
-->

The code reads from two files adds the contents and then writes the information back to a file.

DNA:

Seeking back to start on end-of-file should work exactly as you intended:

-->
stream test 2011-01-24 1c.bb

I see only '2' other thingies that are 'missing' in the code that you posted.
First, the handler for the "." and ".." folder items (which you catch using a filetype check).
Secondly, the check for non-existing files (which is not caught using the same filetype check).

-->
folder entry test 2011-01-24 1c.bb

I have not previously encountered Blitz bugs with file streams (only network streams ^^), so I'm quite sure the problem can be easily traced in your code.
Perhaps if you post some more code, it'll become clearer what's causing the problem.
Perhaps dealing with how handles are closed (and opened), and how files are created, written to, or perhaps deleted, while possibly still being in a loop.

The above 2 programs show various file and folder handling mechanisms that I did not see in your code which I hope you find beneficial

shroom_monk: One of the things I love most about Blitz is that after initial declaration of a variable (e.g. A_FILE$), Blitz no longer demands a identifier's type specification
Similarly: Dim MyArray.MyStruct( .. ) and Global Integer% where % is Blitz's default, which can be omitted entirely

That's not a good thing! That just encourages sloppy coding!

|edit| *LoL*
A lot of new replies while I was typing! |edit|


DNA: Do you close the 2nd file (F2) somewhere else in the code?
I don't see it being closed in this code (CloseFile).
I also do not see the folder being closed (CloseDir).

These functions you posted are good Teasy. Are there any for font smoothing in B2D?

yes, there are many, dna
my favorite is my 'textoutline' function, which is kinda slow, but u have full freedom of color choice every frame etc.
and it works the same as Blitz's Text function, with some added parameters for colors.

i've posted my rendering library here:
http://socoder.net/index.php?snippet=25553
which contains that function.

i'll demonstrate its usage in this program:
-->
textoutline demo - the truth is in here 1a.bb

i also created a 'cache text' function
which wraps this in a memory inefficient (^^) system
to maximize the speed.

instead, i recommend the 'lazypro lib' featurette:
the cachedraw library

which works like this:
-->
the rendering happens in a localized way
and completely independently so.
and the cache is only updated
if your specified parameters change.

-->
cachedraw 1b.bb

a real font smoothing function
is for example my 'font shaper live'
also featured in my game called terra colony.

originally written in 2003,
and suited especially
for making fixed-width fonts look great!

this code includes demonstration:
-->
Font Shaper Live 1b.bb

and finally, something really fancy (yet simple),
a dynamic font bitmapper (on the fly)
which takes any fixed or variable width font
and scales and colorizes it to your liking
with 'lazylib' style interface.

code includes demonstration:
-->
flyfontlib 1e.bb

enjoy!

Are some of these written in BMax?
I get a memory access violation

** I got most of these to run except for the vari font lib which still gives me a memory access violation.

These work but all have jaggies much worse than the normal B2D loadfont at any size.

The problem I was having entailed having jaggies only around the edge.

nope, none for blitzmax.
do u get the error with debug mode turned on?
if so, where does the error occur?

I got the font to display but it is not pretty like your terra colony.
Perhaps something I'm not setting?
