Can    ANDALSO be used with   OR


example:      If grpPhysics.Visible = True AndAlso txtPTrainID.Text <> ""    OR   grpTraining.Visible = True AndAlso txtTrain_ID.Text <> "" Then
                              SaveTraining()
                  ELSE IF grpPhysics.Visible = True AndAlso txtPTrainID.Text = ""    OR   grpTraining.Visible = True AndAlso txtTrain_ID.Text = "" Then
                                InsertTraining()
                 End If

Thanks in advance

Hi TimSweet220;

Yes this syntax should work fine.

    Private Sub Button1_Click(ByVal sender As System.Object, _
        ByVal e As System.EventArgs) Handles Button1.Click

        If grpPhysics.Visible = True AndAlso txtPTrainID.Text <> "" Or _
            grpTraining.Visible = True AndAlso txtTrain_ID.Text <> "" Then

           SaveTraining()

        ElseIf grpPhysics.Visible = True AndAlso txtPTrainID.Text = "" Or _
            grpTraining.Visible = True AndAlso txtTrain_ID.Text = "" Then

           InsertTraining()

        End If

    End Sub


You can also remove the = True as below code shows because Visible is a Boolean.

        If grpPhysics.Visible AndAlso txtPTrainID.Text <> "" Or _
            grpTraining.Visible AndAlso txtTrain_ID.Text <> "" Then

           SaveTraining()

        ElseIf grpPhysics.Visible AndAlso txtPTrainID.Text = "" Or _
            grpTraining.Visible AndAlso txtTrain_ID.Text = "" Then

           InsertTraining()

        End If

Works fine for me... here's the code I tested with. You can manipulate the trues/falses to see what happens:

    If False AndAlso True Or True AndAlso True Then
      MessageBox.Show("Yes")
    Else
      MessageBox.Show("No")
    End If

However, I don't really see any reason to use AndAlso in this instance, why not just use And? You might also make use of some parenthesis to make it easier to read.

Just an additional note... if you're going to use AndAlso, why not use OrElse?
