Hi. I'm making a copy of puzzle panel, a mini game from mario 64 ds. (https://www.youtube.com/watch?v=eDL-1AjquRA)

I need help understanding why my code won't run properly. The program will run but when I try to click on one of the menu strip items that refer to the level, the program will stop and will highlight

Dim picTileClicked As PictureBox = sender and tell me :

"An unhandled exception of type 'System.InvalidCastException' occurred in puzzle panel.exe

Additional information: Unable to cast object of type 'System.Windows.Forms.ToolStripMenuItem' to type 'System.Windows.Forms.PictureBox'

Here I have displayed the procedures that use sender and e

The beginning of my main event:

VisualBASIC:

Private Sub PictureBox_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles _
        PictureBox1.Click, PictureBox2.Click, PictureBox3.Click, PictureBox4.Click, PictureBox6.Click, _
        PictureBox7.Click, PictureBox8.Click, PictureBox9.Click, PictureBox11.Click, PictureBox12.Click, _
        PictureBox13.Click, PictureBox14.Click, PictureBox16.Click, PictureBox17.Click, PictureBox18.Click, _
        PictureBox19.Click, PictureBox5.Click, PictureBox10.Click, PictureBox15.Click, PictureBox20.Click, _
        PictureBox21.Click, PictureBox22.Click, PictureBox23.Click, PictureBox24.Click, PictureBox25.Click

        Dim picTileClicked As PictureBox = sender                       'refering to the picturebox that is clicked
        Dim TileClicked As Integer = Val(picTileClicked.Tag)         'the tag of the picturebox that is clicked




And this is one of the four sub functions that refer to that event

VisualBASIC:

 Private Sub LevelOneToolStripMenuItem_Click(ByVal sender As Object, ByVal e As EventArgs) Handles LevelOneToolStripMenuItem.Click, PictureBox1.Click, PictureBox2.Click, PictureBox3.Click, PictureBox4.Click, PictureBox6.Click, _
        PictureBox7.Click, PictureBox8.Click, PictureBox9.Click, PictureBox11.Click, PictureBox12.Click, _
        PictureBox13.Click, PictureBox14.Click, PictureBox16.Click, PictureBox17.Click, PictureBox18.Click, _
        PictureBox19.Click, PictureBox5.Click, PictureBox10.Click, PictureBox15.Click, PictureBox20.Click, _
        PictureBox21.Click, PictureBox22.Click, PictureBox23.Click, PictureBox24.Click, PictureBox25.Click

        Call lvlOneOriginal()

        Call PictureBox_Click(sender, e)

        If clicks = 0 Then
            Call noClicks(mistakes, score)
        End If

    End Sub

I don't know what's wrong with my code!?!!? Please help! I need this mark!!!
I have attached the full copy of the code in a linked document below in case it is needed.

The error message seems very clear: a ToolStripMenuItem is not a PictureBox, so you can't make the variable assignment that you are trying to do.
