Moving text

i m working on mp3 player n i wish to move the name of the song (only name and not location) scrolling, just as in winamp. can neone help?? please!!

VB Code:

'add:
'label1 as label
'timer1 as timer
 
Const Song As String = "In Extremo - Erdbeermond"
 
Private Sub Form_Load()
  ScrollName (Song)
  Timer1.Interval = 100
  Timer1.Enabled = 1
End Sub
 
Function ScrollName(Name As String) As String
Static N As String
  If Name <> "" Then N = Left(Name & Emp(40), 40) 'enter a songname
  
  N = Right(N, Len(N) - 1) & Left(N, 1) 'move first char to back
  ScrollName = N
End Function
 
Private Sub Timer1_Timer()
  Label1.Caption = ScrollName("")
End Sub
 
Function Emp(Length As Integer) As String
  For i = o To Length
    Emp = Emp & " "
  Next i
End Function

Put a timer on your form and...

VB Code:

Option Explicit
 
Private Sub Form_Load()
 
    Timer1.Interval = 250
End Sub
 
Private Sub Timer1_Timer()
 
    Label1.Caption = Right$(Label1.Caption, Len(Label1.Caption) - 1) & Left$(Label1.Caption, 1)
    
End Sub

hey i tried the codes and it worked fine but it is also showing the whole location of the file.

E.G. c:\my documents\aabb\xyz.txt

this whole string is scrolling n i need only "xyz.txt" to scroll.

plz help

VB Code:

Function FileName(Path As String) As String
  Dim P As Long
  P = InStrRev(Path, "\")               'find the position of the last \
  FileName = Right(Path, Len(Path) - P) 'cut off and return the part after the last \
End Function
 
FileName = Right(Path, Len(Path) - InStrRev(Path, "\")) 'in one line

Search around for string manipulation.

just expanding on Martins code.

VB Code:

Dim str1 As String, str2 As String
 
str1 = Left$(Label1.Caption, InStrRev(Label1.Caption, "\"))
str2 = Right$(Label1.Caption, Len(Label1.Caption) - Len(str1))
 
Label1.Caption = str1 & Right$(str2, Len(str2) - 1) & Left$(str2, 1)

casey.

Of course if you want a more complicated solution leave it to me to provide it.
This method scrolls more smoothly, one pixel at a time, rather than one character at a time.

On your form put a
picturebox (Picture1)
Label (Label1)
Timer (Timer1)
Set index of label control to zero

VB Code:

Option Explicit
 
Private Sub Form_Load()
'set up text display
 
    Label1(0).AutoSize = True
    Load Label1(1)
    Label1(1).Visible = True
    Picture1.Height = Label1(0).Height + 60
    Picture1.ScaleMode = vbPixels
 
End Sub
 
Private Sub Command1_Click()
 'text we want to display
 SetText "Hello World - C Programmer's Group"
 'set scroll speed
 Timer1.Interval = 20
End Sub
 
Private Sub Timer1_Timer()
    ScrollText
End Sub
 
'use this routine to set the display text
Sub SetText(StrText As String)
    Label1(0) = StrText & Space(10)
    Label1(1) = Label1(0)
    Label1(0).Left = 0
    Label1(1).Left = Label1(0).Width
End Sub
 
'Here is where we do all the work
Public Sub ScrollText() 
 Static i As Integer
 Dim k As Integer
 k = i Xor 1 'other label
 'move the label left by one pixel
 Label1(i).Left = Label1(i).Left - 1
 'other label follows like a train
 Label1(k).Left = Label1(i).Left + Label1(i).Width
 'if engine is off screen, then make it caboose
 If Label1(k).Left = 0 Then i = k
 
End Sub

If you get too much flicker with this, then we can get even more complicated.

Cool :thumb: I came up with a way that flickered something awful. This method is much better! :thumb:
