Find the full path of a file for accessing to it (database)

Getting Started

I’ve to find the exact path of a file (database) saved into a network drive (in User/Library/Application Support) so that i can access to that database.
Using this code:

[code]Var f As New FolderItem
f = FolderItem.ShowOpenFileDialog("???")

If f.URLPath <> “” Then
MessageBox(f.URLPath)
Else
MessageBox(“The URLPath is null”)
End If[/code]

I cannot see the Library directory (i’m on a Mac)
How to achieve that ?
Btw why when f is nil the app crashes ?

Btw why when f is nil the app crashes ?
Read the LR to learn about howto avoid that (FolderItem).

You will also find in the same page an answer for your main question (look around SaveInfo).

Hi @Fabrizio Cesare

In this line of code: If f.URLPath <> "" Then you are accessing the URLPath property without checking before If the variable f stores a valid object reference; that is, you’re assuming here that f got a proper FolderItem object from the previous line… but it may not be the case.

For example, you can rewrite it as follows:

[code]Try

Var f As New FolderItem

f = FolderItem.ShowOpenFileDialog("????")

If f <> nil and f.URLPath <> “” Then MessageBox(f.URLPath)

Catch e as IOException
MessageBox e.message
End Try[/code]

In order to access the user Application Support folder, you can try something like this:

Var f as FolderItem = SpecialFolder.ApplicationData.Child("YourFileName")

…and to access the shared Application Support Folder, then you can use something like this:

Var f as FolderItem = SpecialFolder. SharedApplicationData.child("YourFileName")

This is some information you can find here.
