Create Libs in GB32?

[Roger Cabo]

Hi,

I never created a lib in gb32... shame on me..  
Is there a small example how to create my own command like:  PHP_ScriptExtractor()


// This I would do in gb32..
Dim A$()
PHP_ScriptExtractor(a$(), int1% , stringly$, anytype())

Type anyType
 intx As Integer
 inty As Integer
 ints As String*50
EndType

Global anyType(0) As anyType

Function PHP_ScriptExtractor(ByRef a$(), int1%, stringly$, ByRef mytype() As anyType) As Bool Naked
 ...
EndFunction


Are there any restrictions I should generally take care about?

Further I would love to have my own MessageBox with the form, and would that work as well?
I like to display all chars from 0 to 255 in my MessageBox. And the special chars as Dec tokens, not Hex.

Thank you..

How to create LG32 libraries and most of the limitations are covered in the English help file.

Generally you can not use Data/Read constructs, you need to be careful using Global variables and you can not handle OCX Events directly inside a library...and there is more.

Also, to make a library, simply put an $Export line containing the function(s) you want to be usable by other programs.

It is covered in more detail within the help file, however.

 Would it possible to load a library inside a library ?

[dragonjim]

Yes, it is possible to do s, although you need to ensure there are no name conflicts.

Most of the time it works fine, but, sometimes, it doesn't and there may not a logical reason why not.

[dragonjim]

Oh yes, and remember that all functions you want to be available need to be exported, including those within the library inside the library.

I encourage you Roger.
I was hesitant at first to try to create a GFA-BASIC 32 library or .lg32 file.  I am glad I did.
I think you will turn to making more and more libraries as you go along.
As dragonjim says there are limitations and hoops to jump through before you can get them working but it is worth the effort.

One trick I use to quickly go from Lib code to Main code is "App-2" * to load the second file in the recently opened file list. That way you can quickly load the library program, edit changes, Ctrl-s (saves), Ctrl-e <Enter> compiles, App-2 closes current and opens the main program, try out your code then back to the Lib with: App-2, you're back in the Lib code to edit again and so on...

* The App key is the one that looks like a mouse cursor on a menu drop-down. Hold down App and press 2 and you should load the next program in the recent used program list.

Nice tip. Is that something you have posted before?

I think it is worth adding to the help file.

I think it was something that was part of a GLL 'GFA Helper Shortcuts Demo' from a long time ago (in a galaxy far far away...).

Sub Gfa_App_1   ' Load MRU file #1  (Key just before right control key)
 '
 ' Load specified Most Recently Used file in the MRU list...
 '
 '
 ' First, save this file if has been changed i.e.: Dirty...
 '
 If Gfa_Dirty Then Gfa_Save
 
 '
 ' Load the # 1 file  in the MRU list...
 '
 Gfa_LoadMRU 1
EndSub

Sub Gfa_App_2   ' Load MRU file #2
 '
 ' Load specified Most Recently Used file in the MRU list...
 '
 '
 ' First, save this file if has been changed i.e.: Dirty...
 '
 If Gfa_Dirty Then Gfa_Save
 
 '
 ' Load the # 2 file  in the MRU list...
 '
 Gfa_LoadMRU 2
 
EndSub

I split my screen vertically into 2 parts. left, org code and right anything to compare with. Using a 42" 16:9
left windows or right window click && F5.

Don't know if gb32 pre cache the loaded libs into ram, but i think not.

[dragonjim]

Gb32 loads the library either when the program is opened or the $Library line is added to the listing. I haven't tried removing the $Library line and then adding it again. That may work. Otherwise, you have to close and then reopen the calling program to reload the Library.
