B4J Question DirAssets under Windows 11

[johnmie]

Just bought a new computer with Windows 11 on it. Now my app does not seem to recognize DirAssets any more:

    MainForm.Show
    Dim PagesManager As B4XPagesManager
    PagesManager.Initialize(MainForm)
    Log("URI = "&File.GetUri(File.DirAssets, "")&"  Urfolder = "&Z.urfolder)
    MainForm.Icon = fx.LoadImage(Z.urfolder, "Vicon.png") 'File.DirAssets

The log shows: URI = file:/C:/Drive_E/!!B4X/!!Quasi/QuasiList28/B4J/Files/ Urfolder = file:/C:/Drive_E/!!B4X/!!Quasi/QuasiList28/B4J/Files/
File Vicon.png exists in Explorer under: C:\Drive_E\!!B4X\!!Quasi\QuasiList28\B4J\Files

And the program crashes with:

Error occurred on line: 18 (Main)
java.io.FileNotFoundException: file:\C:\Drive_E\!!B4X\!!Quasi\QuasiList28\B4J\Files\Vicon.png (The filename, directory name, or volume label syntax is incorrect)

Is there a problem with the volume label syntax or do I need to download/install another Java version?

Your help is greatly appreciated. Thank you,

How is Z defined? If I load

MainForm.Icon = fx.LoadImage(File.DirAssets, "Vicon.png") 'File.DirAssets

It works as expected and the form icon is set (also under Windows11). Even tested it with the special characters (!!) in the folder names. So I suspect Z instead of File.DirAssets.

Try in release mode.

 

[johnmie]

tried it, but result still negative.

Have you just tried:

fx.LoadImage(File.DirAssets, "Vicon.png")

or

Z.urfolder = File.DirAssets
fx.LoadImage(Z.urfolder, "Vicon.png")

Log(File.DirAssets) = "AssetsDir", <> "file:/C:/...."

 

[Erel]

File.DirAssets has nothing to do with the windows version.
Make sure that the file case is correct.

In Release mode File.DirAssets points into the compiled jar.

Just bought a new computer with Windows 11 on it. Now my app does not seem to recognize DirAssets any more:

    MainForm.Show
    Dim PagesManager As B4XPagesManager
    PagesManager.Initialize(MainForm)
    Log("URI = "&File.GetUri(File.DirAssets, "")&"  Urfolder = "&Z.urfolder)
    MainForm.Icon = fx.LoadImage(Z.urfolder, "Vicon.png") 'File.DirAssets

The log shows: URI = file:/C:/Drive_E/!!B4X/!!Quasi/QuasiList28/B4J/Files/ Urfolder = file:/C:/Drive_E/!!B4X/!!Quasi/QuasiList28/B4J/Files/
File Vicon.png exists in Explorer under: C:\Drive_E\!!B4X\!!Quasi\QuasiList28\B4J\Files

I am sure your app was running in debug mode.

File.GetUri(File.DirAssets, "")

1. It is a wrong usage, you should give a filename existed instead of "", or you will get a warning File is missing and app will crash in release mode

MainForm.Icon = fx.LoadImage(Z.urfolder, "Vicon.png") 'File.DirAssets

2. You can't use "!" as folder name in DirAssets, as Erel said It will become part of jar file.

 

[johnmie]

I know File.DirAssets works also under Windows 11, but I needed to find the absolute location to be able to communicate with other parts of the program, so here is my workaround (after removing leading !! from directory names):

    UrFolder = File.GetUri(File.DirAssets,"Vicon.png")
    Log("File.DirAssets first. = "&UrFolder)
    UrFolder = UrFolder.SubString2(0,UrFolder.lastindexof("/"))
    UrFolder = UrFolder.Replace("/","\")
    UrFolder = UrFolder.SubString(UrFolder.IndexOf("\")+1)
    Log("File.DirAssets abs. = "&UrFolder)

And this is the log result:
File.DirAssets first. = file:/C:/_E/B4X/Quasi/Quasi_25/B4J/Files/Vicon.png
File.DirAssets abs. = C:\_E\B4X\Quasi\Quasi_25\B4J\Files

I'm sure there are more elegant ways.

 

[Erel]

This is only the case in debug mode. In release mode the files are inside the jar.
