    You need to provide much more detail about your issue. What data are you starting with and what do you expect the result to be? I don't use VB6 but if the ListView is like the .NET WinForms ListView then it simply displays text, so the control itself is irrelevant. It's simply a case of what data you have and how you want it formatted.

    I'm having trouble understanding the OP's question as well.

    Do you wish to:
    1. Learn how to use the ListView?
    2. Learn how to write a degree symbol?
    3. Learn how to parse some floating-point number into degrees, minutes, seconds?

    The degree symbol is a standard ANSI character. To print it, just put Chr$(176) into wherever you wish to see it. I made a Form1 with a single label on it (Label1), with the label's font large. Here's the Form1 code:

    Code:
    
    Option Explicit
    
    Private Sub Form_Load()
        Me.Label1.Caption = "123" & Chr$(176)
    End Sub
    
    
    And here's the result:

    If you want to learn how to use ListView and/or how to parse a floating-point number into degrees,minutes,seconds, I'll leave that to others. That last one has recently been discussed here (at your request).

    If you're just getting started in VB6...MY recommendation is to NOT use the ListView, but rather some sort of grid control. SO much easier ("I" think).

    Re: Listview display degree, minutes, seconds

    I have problem to show minutes and seconds symbol in listview. I got like this

    Attachment 191210

    Code:
    With ListView1.ColumnHeaders
    
    .Add , , "POINT", Width / 5, lvwColumnLeft
    .Add , , "ANGLE", Width / 5, lvwColumnCenter
    
    End With
    
    a = 0 + 1
    b = a + 1
    
    
    Set List = ListView1.ListItems.Add(, , a)
    List.SubItems(1) = "123" & Chr$(176) & 40 & Chr$(145) & 50 & Chr$(148)
    
    Set List = ListView1.ListItems.Add(, , b)
    List.SubItems(1) = "100" & Chr$(176) & 30 & Chr$(145) & 10 & Chr$(148)

    Re: Listview display degree, minutes, seconds

    Wouldn't Chr$(146) be the "minutes" notation you're looking for, not Chr$(145)?

    Also, those are ANSI characters, but they're the single-close-paren and double-close-paren. In this application, it seems like the older typewriter symbols (') and (") might be better. To get a (') into a string, just surround it by double-quotes. To get a double-quote into a string, you can either use Chr$(34) or """" (four double-quote-marks).

    Just to explain """" a bit, once in a string, a double-double-quote ("") will insert a double-quote into your string. So, in """", the first quote starts the string, the 2nd and 3rd insert a double-quote, and the 4th closes the string. Done this way (as opposed to Chr$(34)) makes it a compiler operation, rather than a runtime operation (with a compiler operation being faster).
