Problem with Windows Media Player ActiveX control in VBA Powerpoint

it's me and my projects for school again. This time I wanted to insert a video into PowerPoint using file path via WMP ActiveX, so I drew one as follows: (uiMode set to "none")

When the slide show starts, I transfer all data from an Excel file to the presentation, including the paths to the video. Then I hide the WMP with Slide85.WMP.uiMode = "invisible".

When the time comes, I want the WMP to appear at the original size that i drawn and the linked video to play, so I used these codes:

Slide85.WMP_TT.uiMode = "none"
Slide85.WMP_TT.URL = "C:\inetpub\wwwroot\TT2.mp4"
Slide85.WMP_TT.Controls.Play

Already muted the video by changing the settings in the Properties tab.

Then the result came out like this:

The video still plays, but only with sound, which is impossible because I muted the control. No visual images is shown from the video, and the control's dimensions changes too.

As of now I cannot think of any causes to this problem. Please help me, I'd be very grateful.

As mentioned on this Microsoft help page, you have to set height and width parameters in code for the player to reserve the space when triggering uiMode="invisible": Player.uiMode

As an alternative, you can draw the size as you have done, then use VBA to hide or show it on the slide with code like this:

Sub HideWMP()
    Dim oSlide As Slide
    Dim oShape As Shape
    For Each oSlide In ActivePresentation.Slides
        For Each oShape In oSlide.Shapes
            If oShape.Type = msoOLEControlObject Then
                oShape.Visible = msoTrue
            End If
        Next oShape
    Next oSlide
End Sub
