Hi,
I tried to use App.ExeName to locate the current executable.
This function exists in Jabaco, but returns an empty string.

Any idea how to find my own executable?
I'd like to know the path to open a configuration file in the same directory.

Greetings

Quoted

I'd like to know the path to open a configuration file in the same directory.

Why don't you just open it like this:

	Jabaco Source
1	Dim file as vbfilehandler = open "yourfile"

Just open "yourfile" and it's okay. No need of EXEName.
And App.Path works
To open it (second way) do this:

	Jabaco Source
1	Dim file2 as vbfilehandler = open app.path + "" + "yourfile"

Hi,
App.Path points to the current working directory which was true when starting the application.
This is not necessarily the directory of the executable.
Example: I start my Jabaco IDE via a desktop icon. This determines the current working directory to be somewhere on my desktop.
Far away from the Jabaco project directory.

But you are right: When you compile an exe file and start it using the exe's directory, App.Path works as expected.

Opening a file without specifying the path, leads to the same situation:
The file is assumed to be in the current working directory.

One workaround would be to start the exe in the directory of the configuration file.
But this is not really flexible for using Jabaco executables from CMD skripts.

Greetings!

Hi,

i found something - maybe it's interesting:

Jabaco Source

Public AppPath As String
 
Public Sub Form_Load()
   AppPath = GetAppPath
   MsgBox AppPath
End Sub 
Public Function GetAppPath() As String
   Dim appURL As URL
   appURL = getClass.getResource(".")
   Dim s As String = appURL.getPath
   GetAppPath = Replace(s, "%20", " ")
End Function

in fact it returns the folder that jabaco creates in the temp-directory.

greetings

works onlu in IDE for me

I tested this code and it works perfectly here (though changing "URL" with "url" in line 8 ) when i launch the app in jabaco IDE.
But, if i compile the program, it gives the error reported below.
Any ideas about why?

Try the following:

Jabaco Source

Option Explicit

Public AppPath As String
 
Public Sub Form_Load()
   AppPath = GetAppPath()
   MsgBox AppPath
End Sub 

Public Function GetAppPath() As String
   Dim classPath As String = System.getProperty("java.class.path")
   Dim pathSeparator As String = System.getProperty("path.separator")
   Dim fileSeparator As String = System.getProperty("file.separator")
   Dim cp() As String 
   Dim s As String 
   
   cp = Split(classPath, pathSeparator)
   
   s = cp(0)
   If Right(s, 8) = ".exe.jar" Then
      cp = Split(s, fileSeparator)
      
      s = Left(s, Len(s) - Len(cp(UBound(cp))) - 1)
   End If
   GetAppPath = s
End Function

Thank you very much!
It somehow works, even if under IDE it returns the program working folder, compiled as JAR, it shows the complete file.jar file path and compiled as .EXE it gives a \temp folder path....
It's a shame ther is not an easy, direct way to geth the program folder path!

App.EXEName does not return paths in VB6, just a simple name. For "C:\blahblah\Project1.exe" for example it returns "Project1" alone.

App.Path is supposed to return the path to the compiled EXE w/o the "\" as in "C:\blahlah" alone. However it is broken in Jabaco and returns the current directory. This is very sad.

Speaking of that, the ChDir statement is completely missing in Jabaco.
