I have made a visual basic 2008 express program which uses the windows media component to make my own version of media player. i can start and stop media, select which file i want to play but i cannot find a way to change which visualisation is being shown. does anybody know how to change visualisations programatically?

Thanks in advance,
Jon

Try exploring the IntelliSense lists to see if there are any object members you can change.

I assume by that you mean the lists that appear while you type code (Sorry i am quite new to this) if so then i have tried already and cannot seem to see anything that referenced to Visualizations and i cannot seem to find anything on the net about this.

Thanks for you prompt reply,

Jon

Here is the MSDN link for creating and rendering custom visualizations. All you should need is the rendering section I would think:)
Custom Visualization Programming Reference

That seems to be the stuff i am looking for.

Sorry for being really thick but i cannot work out how to get to these things

e.g.

the render method.

I can set play states easily e.g. Player.Ctlcontrols.stop() but i cannot seem to find the render option anywhere.

Thanks for all your help so far.

OK forget my last post. I am getting somewhere, but have hit a wall and i think its something silly.

The code i have is

Dim Vis As IWMPEffectsCtrl
Label1.Text = Vis.CurrentEffect

But it gives an error message: Variable Vis has been used buefore it has been assigned a value.

what do i need to add?

Vis needs to be instantiated in OOP. Try this:

[HIGHLIGHT=vb]Dim Vis As New IWMPEffectsCtrl()
Label1.Text = Vis.CurrentEffect[/HIGHLIGHT]

Thanks for all your help so far.

OK i tried that change (added 'New') but this time i get:

"'New' Cannot be used on an interface"

Any suggestions?
