Hello,
I have been trying to code an mp3 player. It will have some features like winamp.
I tried to implement showing, removing and padding the playlist item numbers. Under Winamp Preferences, on the playlist window there is a checkbox captioned "Show playlist item numbers in Playlist Editor". When you check it, it will add numbers and removes when unchecked. Also there is another checkbox captioned "Zero pad item numbers".
Could anyone help me with this?
Thanks.
Since no one has responded to your post, perhaps you should post the code in question. Sometimes members shy away from topics that involve controls that they're not familiar with. However, sometimes the answer to a question may be more of a general coding issue that doesn't require familiarity of a control.Quote:

You haven't had any replies since CDRIVE's because you haven't given us the info he asked for (the code).
We have absolutely no idea how your program works at the moment, so we can't tell you how to make the changes you want.
There are many people who are willing to help, but you have to give us enough information to let us do that.
I think my question is clear enough. But I can re-ask it.
Suppose that, you have a lot of song names in a listbox. When you click the OPTIONS sub-menu, you have a window containing a few options that let you change some settings. There are only two options for the listbox.(2 checkboxes).
checkbox 1
caption: Show playlist item numbers in Playlist
When you tick it, it will add numbers at the beginning of the song names.
checkbox 2
caption:Zero pad item numbers in Playlist
When you tick it(after ticking the first checkbox), it will add some zeroes at the beginning of the numbers, comparing the digits of the numbers.
I think you all played with Winamp's settings. I want to do the same thing that Winamp does. I dont know how to code it.
Thanks.
Never assume that we know how a certain program works, as we don't all use the same programs you do, or the same versions of those programs (in this case your explanation of what you want is good, so it doesn't matter).
More importantly, don't assume that we have any knowledge at all about your program - in your first post there wasn't even any indication that you were using a ListBox, which at least gives us something to work from.
To add numbers in front of all items in a ListBox, you can use code like this:
To zero pad the numbers use the Format function, eg:Code:Dim lngLoop as Long
For lngLoop = 0 to List1.ListCount - 1
List1.List(lngLoop) = CStr(lngLoop + 1) & " - " & List1.List(lngLoop)
Next lngLoop
That pads to a fixed two digits, which may not be enough for all the items in your list - to automatically use the right amount of digits you need to detect the length, and build the padding string to that length, eg:Code:List1.List(lngLoop) = Format(lngLoop + 1, "00") & " - " & List1.List(lngLoop)
To remove the numbers use the InStr function to find the separator (" - "), and use the result of that to get the Right of the string.Code:List1.List(lngLoop) = Format(lngLoop + 1, String(Len(List1.ListCount),"0")) & " - " & List1.List(lngLoop)
try this:
Code:Private Sub Check1_Click()
Dim i As Integer
Dim number As String
number = "1256"
For i = 0 To List2.ListCount - 1
With List2
.List(i) = number & .List(i)
End With
number = number & i
Next i
End Sub
Private Sub Check2_Click()
Dim x As Integer
Dim i As Integer
Dim ListItem As String
For i = 0 To List2.ListCount - 1
With List2
ListItem = .List(i)
For x = 1 To Len(ListItem) 'we go through the string char by char
If IsNumeric(Mid(ListItem, x, 1)) Then 'we check if char is numeric
.List(i) = "0" & .List(i)
End If
Next x
End With
Next i
End Sub
