Displaying duration of a directx object.

I'm trying to create my own controls for a directx object that will show a video, specifically a trackbar so the user can slide it along and the video will fast forward or reverse along with it.

I'm taking this one step at a time and the first thing I want to do is show the duration of the loaded video, but I'm having a little difficulty. I've created a string object and i'm using the Following:

GetDuration( "Direct Show" )

Which I assume will get the length of the video loaded in, but I can't get the text object to display the duration. I tried using the following:

val(GetDuration( "Direct Show" ))

But it gives an error: "Mixed string and numbers". How to I get the string object to display the duration? Or are there any other objects that would allow me to display the duration? Any help appreciated.

str$(GetDuration("Direct Show")) i'd imagine

Val() is for converting a string to a value.

Str$() is for converting a value to a string.

Already tried that :)

Get the error "Please enter a numeric expression".

xyzzy has to be right :/

Are you sure you are setting the alterable string and not the paragraph number?

Str$(GetDuration( "Direct Show" ))
This works fine for me.. just tried it!

I wonder why it's giving me the error when I 'Check current expression'.

Did you try it without the str$()?
The number of the paragraph would be a value not a string.

Ahh, thanks Jamie, now I see it's asking for a paragraph, I assumed it was just displaying text. Do I have to set an alterable string / value somewhere and read that in?
