Ok, so this is just a simple SWF (Flash) Player.
Insert 1 Shockwave Flash Object, 1 Button and 1 OpenFileDialog
*Note:* To get shockwave flash object go to choose toolbox items, COM components, Shockwave flash object

In OpenFileDialog Properties insert this code into Filter(makes sure only SWF files can be played)
Double click and insert this code into Button1(Selects SWF File)
Code:
Try
OpenFileDialog1.ShowDialog()
AxShockwaveFlash1.Movie = OpenFileDialog1.FileName
Catch ex As Exception
End Try
Eventually i will show you how to make a trainer for any SWF(flash) game through axshockwaveflash
