Hi all,
I want to develop an level output meter like an 8 band equalizer. I saw some implementations to show a waveform, but this is not what I want. In the end the control should work like the winamp level meter. Has anybody an idea how to start?
Thanx!

I'will try to make it more clear. I developed a little tool for organizing and playing mp3 albums and files. To play the files I'm currently using the media player control. All that I want is to visualize the currently played mp3 in an 8-band level meter.
I'm using Visual Studio Express 2005.
Need more information?

It's called a "spectrum analyzer". This is actually going to be quite difficult to do. You can only use the data that is currently going through the audio mixer to feed the analyzer. Reading the MP3 file directly will do you no good because you can't tell where the current sound is in the file.
You can find an example of this here[^], but I'll warn you, it's not for the beginner.
You can also find more about them on Google, here[^] or even find libraries that can do this for you.

What do you want to do ? Showing them is fairly easy, if you embed IE in your app, it will do it. Creating them requires a third party library.

How r u making the listview control in the editing form?

A ListView isn't databindable, so that'll make this quite a bit more difficult. Why are you using ListView control? Why not a DataGridView?
It's possible to implement your own bindable version of the control, though. You can find an example here[^]. Warning! It's not something for beginners!

Hi Vuyiswamb
Try server side validation control, use date validation control, and use the "control to validate" property.
Hope it will help ![Rose | [Rose]](https://www.codeproject.com/script/Forums/Images/rose.gif)

Hi Vuyiswamb
Go through your toolbox there is a validation control
section, in that u get a date validation control, use that control...OR if you don't know how to use the control then just go through the MSDN and take help abt the validation control.

dear prasad..
i think this is wht u want...
add the OLE component from the toolbox in to the form. it will ask you the object type. select the Microsoft Word Document from the list...
Private Sub Command1_Click()
OLE1.SourceDoc = "Complete path of your word file"
OLE1.Action = 1
OLE1.SetFocus
SendKeys "{ENTER}"
End Sub
try this...
