Android Question [Solved]Problem about filehandler library.

[Olaan]

I need create excel file via creating csv file ,but I have some error code. How to solved it?

P.S. I have to use non-b4xpages coding strategy.

Unknown type: contentchooser<br />Are you missing a library reference?

Unknown type: b4xset<br />Are you missing a library reference?

You are missing these library references
1.FileProvider
2.B4XCollections
3.SQL

I still have error message as belows
[Quate]
B4A Version: 13.30
Parsing code. Error
Error parsing program.
Error description: Undeclared variable 'b4xpages' is used before it was assigned any value.
Error occurred on line: 82 (FileHandler)
Dim Activity As Activity = B4XPages.GetNativeParent(B4XPages.MainPage)
[/Quate]

I think about FileHandler library is not supported both of Non-B4XPage and B4XPages likes this

Where you get the problematic code from?

Where you get the problematic code from

If you mean that non-b4xpage andB4XPages supported, I've tried for testing both of them.

 

[aeric]

Can you point which example you are using?

In MyLib , I will code both of them as belows when I create a project by using non-b4xpage, it will be supported , on another hand, when I create a project by using b4xpages, it will be supported, as well. (refer to the same library)So I think filehandler lib lacked this.

Try
    'using  B4XPages  code
 

Catch
     'using  Not B4XPagescode


End Try

B4XPages is the way to go.
Don't waste your time on the default template.

SaveAs - Let the user select a target folder + list of other related methods

In TextEditor example.There is Filehandler.bas file,and Filehandler.b4xlib is additional lib.

The example is B4XPages project.
Filehandler is a class file.

Don't mix B4XPages with non-B4Xpages project if you are not sure what you are doing.

Don't add a reference to B4XPages library if this is not a B4XPages project.

So I did it only mylib for myself.
