[Gambas-user] failure on Startup of Gambas on Linux Mint Debian Edition 2

2016-03-14 Thread KKing 
I've just had to set up a new unit and am using Linux Mint Debian 
Edition 2 usuing 32bit MATE,

If I install Gambas via the LMDE2 Package Manager it installs gambas 
v3.5.4-2+b1

But when i try to start Gambas from the menu, I get a window

This application has raised an unexpected error and must abort.
[13] null object
Setting.WriteWindow.385

I uninstalled (completely remove option) gambas via the Package Manager.

Then I downloaded source from gambas site for v3.8.4

installed the dependencies mentioned on the wiki for debian, plus two 
more for qt4 opengl and qt4 webkit. I still had qt5 Opengl and qt5 
webkit listed as disabled  do I need them to use Gambas if the Qt4 
is resolved?

I couldn't see Qt5 libraries on the LMDE2 Package Manager?

If I try to start gambase from terminal, I get window.

This application has raised an unexpected error and must abort.
[20] Bad argument
Settings.WriteWindow.388

and in the terminal window there is
Project.Main.356

  - - - - - - -
Anything obvious I can try? Or what would be next debugging step to 
establish issue.

ta, I did contemplate the GetChildren methods.
Due to time pressures, and a very specific need, I resorted to modifying 
the xml file via string manipulation.

If I ever need to revisit I may look to do it better, either within my 
code or extending the component.
Would XPath fit within the gb.xml component, or would you imagine a 
gb.xml.xpath component?

I possibly encountered similar issue(s).
I was working with text in a SQLite db that contained things like the 
degrees symbol and superscript characters. Populating Gambas textBoxes 
and textAreas from the db and updating the db with these characters was 
no issue. But when went to save the same content to a text file I was 
get those characters being prefixed with a "Â", e.g. "³" instead of 
just "³".

I ended up using the following, which worked for me for my issue.

   Try sTextArea = Conv$(taDescription.Text, "UTF-8", "WINDOWS-1253")
   If Error Then
 Message(Error.Text)
   Endif

I've got around my problem for now by totally doing the changes I need 
via string manipulation.

I'll try to find time to test on another unit and or compile current 
Gambas version from source.

[Gambas-user] XmlDocument.Open(filename) gives NULL

2016-02-16 Thread KKing 
I'm using Gambas 3.5.4 on Linux Mint

I want to use XmlDocument but can't seem to load an existing xml 
document file.

It errors on loads and just gives error text of "Null object"

I can open and read the same file via XmlReader, but I want to work with 
the whole document via DOM.

Is this likely to be something in the version of 3.5.4 that I'm using, 
that if I take trouble to compile newer version from source will resolve?

Or am I misunderstanding usage of the XmlDocument?


Below is a simplified version I tested with, and hit same issues.

simple test xml file:  myTest.xml
  = = = = =

 1

  = = = = =

tPathAndFilename = "/home/user1/test/myTest.xml"

Try xDoc.Open(tPathAndFilename)
 If Error Then
 Debug Error.Text
 Endif
