Yeah... I`ve used the CONCAT$ before, I just didn`t think of using it here.
And boy is that a pain in the arse! I`m remembering how crude Basic is...

I`ve said here many times, it takes 10 lines of Visual Basic for 1 of Bash.
Bash script`s intimidating as you start learning it, but it`s very powerful.!
But BaCon will compile! Too bad there isn`t a real converter for script to C.

P.S. Hey GatorDog, should I post a pic. of my app. here for all to see?

A BaCon-HUG GUI front end for pDebThing, a Debian package downloader.
I wrote another GUI in gtkDialog, they both use the same Bash script backend.
I could have written more of the backend code in BaCon Basic,
. but it just calls shell commands anyway, so I didn`t write much of it in BaCon.

This is a good example of the type of GUI`s I talk about, with no backend code.
This way the backend and frontend ( GUI ) code is separate and replaceable.
Here there is one set of backend code and two sets of frontend code I wrote.
More GUIs could be written in Perl or Python, and the backend C or whatever.

Both GUIs look the same as they both use GTK widgets.

# The first pic. is the main tab panel of the Debian downloader.
The left ListBox shows the groups of packages.
Click a group and it`s list of packages shows in the right ListBox.
The right ListBox shows the packages in the selected group.
Click a package and it`s description info. shows on the second tab panel.

# The second pic. is the second tab panel that shows the description info.

Looking neat and clean

GatorDog; Trying to get the GUI to show all the info.
Here`s one part for the first listbox, the second`s the same.
The var. TMP$ is set above and the files exist. What`s wrong?

[GatorDog]

Terry,
I think your file I/O code itself is OK.

I'm guessing that for the top code snippet that you're getting a blank List?
I'll bet you a Little Debbies Chocolate Snack Cookie that "main.list" has
a final newline (NL$) character. NL$ is the default seperator when reading
in a text file. So, the final NL$ is seperating the text before it from the "nothing" (ie. null)
after it. So the final thing the TEXT(lstGRPS_,TXT$) is a null character.
Guess what that does. It clears the list box.

If you want to skip blank lines, you can put this in the WHILE loop
IF CHOP$(TXT$) = "" THEN CONTINUE
That will just skip processing that line and go read in the next line.
If you want the blank line, then substitute in a space for that list line.
IF CHOP$(TXT$) = "" THEN TMP$ = " "

An edit widget is cleared the same way, TEXT(Edit_widget_, "").
But your code there is adding a NL$ to each line so I don't think that's a problem there.

ed. Snack Cookie vs. Snake Cookie

Hey GatorDog; Look above at the corrected first listBox, I`m sure that`s right...
The listboxes are still empty...

I see that the CHOP line is removing blank lines.
And you`re right... All 3 lists have a trailing blank line or more.
All 3 files are there for this testing, and are there sometimes during operation.

I assume the info. editBox handles null lines, other wise it couldn`t show them.

### Q: Would this work also: IF TXT$ <> "" THEN TEXT(lstGRPS_,TXT$)
It gives a compile error: Cause: expected expression before token ","

[GatorDog]

sunburnt,
I don't spot anything yet that looks out of place, but I may be looking through
the wrong section of my tri-focals

If you'd like to, either upload your code and the sample files your working with
or PM them, and I'll take a look.

Hey GatorDog; Well your code was needed as always, of course.
But in the final code error it was just my stupid code holding it up.

Posted the pics. of the working GUI displaying Debian packages and info.
I had to widen the GUI to get rid of the hoz. scroll bar, I`ve seen this before.
What`s weird is that the text isn`t anywhere near the edge of the listBox.

# Same Q: This should work also: IF TXT$ <> "" THEN TEXT(lstGRPS_,TXT$)
It gives a compile error: Cause: expected expression before token ","

When I get help with mtPaint, I`ll come back and clean up the pics.
The code`s very long, but when it`s fully functional I`ll post the BaCon file.

# Note: I think I`ll try editBoxes instead of the 2 listBoxes.
..... The listBoxes waste space between the lines, not very efficient.

Thanks again buddy... Terry

Gui starts and quits, didn`t change anything big, added a Combo.
I stared at it for several hours, so post it and sleep.

# A compiled Bacon gui`s fairly portable I think... Should work on most Linuxes?

So if you get a few minutes to stare at it GatorDog...

[GatorDog]

sunburnt,

1. Try setting a Var$ to the CONCAT$( path/filename.... and then use
OPEN VAR$ .
I think that is causing the crash.

2. You have two CLOSE FILE's in a row, but I think main problem is #1.

3. I put in a filedialog to getcha' a filename. I used a button to call it but
you'll probably want to call it from the program.

-----
I put all of the "OPEN FILE AS..." inside of a SUB since I don't have those
files on my system. It's just a cheap trick way of commenting them out

Hey GatorDog

Im trying to get your first example compile to test it

this tell me I have to recompile no big deal
