Man I SUCK Today!!!!! Select Case Statment

What's wrong with this? I'm trying to set column widths in a listview!

VB Code:

Private Sub CmdSaveExit_Click()
 
Select Case Checked
Case ckFilename.Value = Checked
    Kamo2.ListView1.ColumnHeaders(1).Width = 4000
Case ckFilesize.Value = Checked
    Kamo2.ListView1.ColumnHeaders(7).Width = 1301.1
Case ckArtist.Value = Checked
    Kamo2.ListView1.ColumnHeaders(2).Width = 3200.31
Case ckSongname.Value = Checked
    Kamo2.ListView1.ColumnHeaders(3).Width = 3200.31
Case ckAlbum.Value = Checked
    Kamo2.ListView1.ColumnHeaders(4).Width = 2700.28
Case ckTrack.Value = Checked
    Kamo2.ListView1.ColumnHeaders(5).Width = 899.71
Case ckFrequency.Value = Checked
    Kamo2.ListView1.ColumnHeaders(8).Width = 1440
Case ckBitrate.Value = Checked
    Kamo2.ListView1.ColumnHeaders(9).Width = 899.71
Case ckLength.Value = Checked
    Kamo2.ListView1.ColumnHeaders(10).Width = 1301.1
Case ckGenre.Value = Checked
    Kamo2.ListView1.ColumnHeaders(6).Width = 1440
End Select
 
Select Case Unchecked
Case ckFilename.Value = Unchecked
    Kamo2.ListView1.ColumnHeaders(1).Width = 0
Case ckFilesize.Value = Unchecked
    Kamo2.ListView1.ColumnHeaders(7).Width = 0
Case ckArtist.Value = Unchecked
    Kamo2.ListView1.ColumnHeaders(2).Width = 0
Case ckSongname.Value = Unchecked
    Kamo2.ListView1.ColumnHeaders(3).Width = 0
Case ckAlbum.Value = Unchecked
    Kamo2.ListView1.ColumnHeaders(4).Width = 0
Case ckTrack.Value = Unchecked
    Kamo2.ListView1.ColumnHeaders(5).Width = 0
Case ckFrequency.Value = Unchecked
    Kamo2.ListView1.ColumnHeaders(8).Width = 0
Case ckBitrate.Value = Unchecked
    Kamo2.ListView1.ColumnHeaders(9).Width = 0
Case ckLength.Value = Unchecked
    Kamo2.ListView1.ColumnHeaders(10).Width = 0
Case ckGenre.Value = Unchecked
    Kamo2.ListView1.ColumnHeaders(6).Width = 0
End Select
 
Unload Me
End Sub

I also tried: Select Case True & Select Case False w/ no luck!
Any help appreciated.

try this.

Select Case True
Case (checkbox1.value=checked)
msgbox "1"
case (checkbox2.value=checked)
msgbox "2"
End Select

It works, but only for the first checkbox that is selected. It changes the listview columnwidth. Here's what I'm try to avoid by using a Select Case statement:

VB Code:

If ckFilename.value = Checked Then
    'set columnwidth to certain size
Else
   'set columnwidth to 0
End if
etc..

I have to do this for like 9 checkboxes and I don't want 9 IF..THEN...ELSE statements. I don't see what's wrong with my Select Case code though.

Any suggestions appreciated.

That's the idea behind the Select Case structure. Only one branch will execute, that's all.

:)

Is there a better way then 9 IF Then statements? Maybe a control array or something here?

Looking at what you are trying to do, I would say it would be near impossible to avoid checking each value.

try making your ckboxs an array of controls then cycl thru them with

Dim ckbox as CheckBox
Set ckbox as ckArray

for each ckbox in ckarray

if ckarray(ckbox.index).value=vbchecked then
'whatever you want
end if


next ckbox


Hope this helps

oh yea , correlate the index of column headers with the index of the checkboxs. Then you can shove the select case structure inside of the if statement. By the way the case you are looking at is the index of the checkbox

Assuming that u are only using vbchecked and vbunchecked (ie not vbgray) then u can dispense with If Then and Select Case altogether. Simply multiply the width by the checkbox value

VB Code:

eg
With Kamo2.ListView1
    .ColumnHeaders(1).Width = 4000 * ckFileName.Value    
    .ColumnHeaders(7).Width = 1301.1 * ckFilesize.Value
    .ColumnHeaders(2).Width = 3200.31 * ckArtist.Value
 
'etc
'etc
 
End With

Also looks a lot nicer eh? :p You could also pass values, indexes to function etc... I am not sure about your use of fixed values in widths as this usually causes problems in diff screen sizes. Maybe use percentages?

like bam said, but a little more detailed:

- make a chkBox(1 to 10) array
- store the used column width in the chkBox.Tag property, so the User can dynamically resize the column if he wants

VB Code:

Private Sub Form_Load
 
chkBox(1).Tag = 4000 'Filename
chkBox(2).Tag = 3200 'Artist
chkBox(3).Tag = 3200 'Songname
chkBox(4).Tag = 2700 'Album
chkBox(5).Tag = 900 'Track
chkBox(6).Tag = 1440 'Genre
chkBox(7).Tag = 1300 'Filesize
chkBox(8).Tag = 1440 'Frequency
chkBox(9).Tag = 900 'Bitrate
chkBox(10).Tag = 1300 'Length
 
End Sub
 
 
 
 
Private Sub CmdSaveExit_Click
 
Dim i As Long
 
For i = chkBox.Lbound to chkBox.Ubound
    If chkBox(i).value = Checked Then
        'set columnwidth to certain size
        Kamo2.ListView1.ColumnHeaders(i).Width = chkBox(i).Tag
    Else
       'set columnwidth to 0
        Kamo2.ListView1.ColumnHeaders(i).Width = 0
    End if
Next i
 
End Sub

HTH
Felix

why not put a tag on each of the checkboxes then add some code to the click event

VB Code:

Private Sub Check1_Click()
Dim nwidth As Long
 
nwidth = Val(Me.Check1.Tag)
 
End Sub

i like felix's solution, didn't think about the tag prop
