Android Question Edittext Box Question

[Gavin O'Connor]

Hi All,

I am trying to bring up a Message Box and halt the program if no data is entered into an Edittext Box

Currently I am using:

Sub Button1_Click
   
    If EditText1.Text = " " Then
    Msgbox ("Please Enter a Serial Number", "360" )
    End If

    File.WriteString(File.DirDefaultExternal, EditText1.Text & ".txt" ,  txtLog.Text)
    Msgbox ("Info Saved", "360")
   
    End Sub

In the Old VB6 Days I could use the following:

If Len(edittextbox1.Text) = 0 Then
Msgbox ("Please Enter a Serial Number", "360" )
Exit Sub
End If

Any ideas on how we can do this?

If EditText1.Text = " " Then
Msgbox ("Please Enter a Serial Number", "360" )
End If

If EditText1.Text.Length = 0  Then
    Msgbox ("Please Enter a Serial Number", "360" )
    Return
End If

Sub Button1_Click
  
    If EditText1.Text.Trim= "" Then
        Msgbox ("Please Enter a Serial Number and Click Ok", "360" )
    Else
        File.WriteString(File.DirDefaultExternal, EditText1.Text & ".txt" ,  txtLog.Text)
        ToastMessageShow ("Info Saved", False)
    End If
      
End Sub

Thanks! - Worked like a Dream!

Tip: use MsgboxAsync instead of Msgbox. It is always better and especially inside the Click event. The modal version (Msgbox) can cause a hard crash in some cases.
