Dir() and wildcards

Experimenting with Dir(). If a file "c:\test.txt" exists, Dir() seems to only partly work:

sFile=dir("c:\test.txt") returns "test.txt" meaning the file's existance was found.

sFile=dir("c:\*.txt") returns blank, when VB would have returned "test.txt" (applying the wildcard.)



Is it possible Jabaco uses a different wildcard character than "*" (asterisk)?

Currently wildcards are not supported. Dir() is currently only a raw implementation. Have a look at its code:
http://code.google.com/p/jabacoframework…System.jsrc#321

But if you download the svn, there is an example program included, where you can browse throw the directorys.

Here a part of it a little bit changed for you. Possible it helps ypu:

This sample raises the question of how to define a genuine Java array in Jabaco code.

"Dim myList" does not specify a variable type. The return value to myFile.listFiles, however, is an array of File.

Is there any proper way in Jabaco to define array variables like "myList" with an explicit variable type?
Out of a similar reason I have not managed to call a Java function out of Jabaco which requires an array of char parameter.
Any ideas?

Greetings!

In VB it would be "Dim myArray() as Byte" (etc), you can redim later to set bounds, but starts as an empty array--I tried this with Jabaco at one point and it seemed to work...
