hi,

how do I get the trackbar to display the playing time when opening a mediafile, and when starting to play, to update the trackbar to the playing position.

Hellfire, try this:

Trackbar1.Position := MediaPlayer1.Position

Good luck with your project!

P.S. You may also have to set the start and end positions (min/max) of the trackbar to correspond with how many "frames", etc are in the media file.

Not the solution you were looking for? Getting a personalized solution is easy.

Ask the Experts
side note: MediaPlayer1.Position is a a time value. Depending on what time values you want (minutes, seconds, etc) you will have to do some time juggling to get the trackbar to sync with the mediaplayer. Also, use a TTimer (about 1 sec) apart to set the trackbar position.

If you just need to indicate what track it's on, use MediaPlayer1.Trackposition.

I have decided to use a progressbar, Now this is used different then Trackbar so could you please explain how to use this, when searching in help it says to look at StepIt, but when I click on the example button I get an error saying not found, so help!!
and also, when mediaplayer is open how do I close it? I tried
If MediaPlayer1 := open then Mediaplayer1.close; but it didn't work. it is the first time I use MediaPlayer and a progressbar.
thanks.
Hellfire, what type of media are you playing with the media player? .WAV files? CDs? Curious because the routines are a little different for each.

The StepIt method is used as follows:
ProgressBar1.StepIt;

It's just a convienient way to increment the progress bar. Each call to StepIt will increment the progress bar the amount of the Step property.

to Stop the Mediaplayer issue Mediaplayer1.Stop

to actually make it "go away" (hide it, but leave it available) issue Mediaplayer1.Visible := False;

regards,
Pegasus

with the Mediaplayer1.stop I know how to call it, but how do I check if MediaPlayer1.open is true and if so then to close it.
and also vice versa.

The idea was to make a general mediaplayer, so that it would play all supported files. (I use the autoselect for mediatype)

And how to use that progressbar?
if I open a file, I should set the min tracktime as 0 and the max tracktime as 100 for the progressbar, and when starting to play to increment the progressbar, probably with a timer.
But I have no idea how to make this, could you give a small example??
Thanks
