Hi, here is my code.

I'm using b4a version 9.50 with Net Library 1.8 in default folder.

FTP.Upload multiple files:
For i =0 To Qty-1
            
            Cursor1.Position=i   
            
        
            FileName=Cursor1.GetString("VoiceMessageFileName")
        
            If FileName<>"" Then
        
                If File.Exists(File.DirRootExternal,FileName) Then
            
                    RecordID=Cursor1.GetInt("ID")                   
                    Dim sf As Object =FTP.UploadFile(File.DirRootExternal, FileName, False, FileName)
                                        
                    Wait For (sf) FTP_UploadCompleted (ServerPath As String, Success As Boolean)
                    If Success Then
                        Log("VM file was uploaded successfully")
                    Else
                        Log("Error uploading VM file")
                    End If
                    
                End If
            End If
            
        Next
Here is my compilation error

If I use this code

FTP.Upload multiple files without wait:
For i =0 To Qty-1
            
            Cursor1.Position=i   
            
        
            FileName=Cursor1.GetString("VoiceMessageFileName")
        
            If FileName<>"" Then
        
                If File.Exists(File.DirRootExternal,FileName) Then
            
                    RecordID=Cursor1.GetInt("ID")                   
                    'Dim sf As Object =FTP.UploadFile(File.DirRootExternal, FileName, False, FileName)
                                        
                    'Wait For (sf) FTP_UploadCompleted (ServerPath As String, Success As Boolean)
                    'If Success Then
                    '    Log("VM file was uploaded successfully")
                    'Else
                    '    Log("Error uploading VM file")
                    'End If
                    
                    FTP.UploadFile(File.DirRootExternal, FileName, False, FileName)
                    Sleep(4000)
                    
                End If
            End If
            
        Next
compilation works fine without error.


Please advise.

Thanks

Problem solved.
I removed Net library jar/xml files from default library folder and put them into additional library folder.

But they were in default library folder since I installed b4a on my computer.


Correction.

Net library files that were installed with b4a 9.5

Net.jar 219261 12/04/2019 13.37
Net.xml 28984 12/04/2019 13.37

Net library files that were downloaded as Net.zip file from this web site

Net.jar 220835 10/04/2018 13:03
Net.xml 28984 10/03/2018 10:09

The weird thing is that if I replaced Net library files that were installed along with b4a 9.5 with files from Net zip files in additional library folder compilation works fine.
If I use original files in additional library folder that were installed along with b4a 9.5 - I'm getting error.

And b4a library panel shows Net library version as 1.8
