Populating listview

I guess this will be fairly tricky(maybe not) so i'm hoping somebody knows of a tutorial or pre-made code for populating a listview from a text list.

My text list data has 2 delimiters "|" and "," and is of the form

path filename|filesize,path filename|filesize etc

example being c:\file1.exe|34502,c:\file2.exe|31233..etc.

Well my task is to read any length of list, as in the example, and display in a suitable way.

I sorted most of this out apart from one thing, how to you extract part of a string that lies inbetween 2 different delimiters?

like ,file1.exe|32123,file2.exe|432432,

So i need the split to start at the "," and stop at the "|" so as to extract the file size .

I need a kinda reverse Mid that allows characters delims.

Split first on "," you'll get an array from that, say arrFirst(). To assign the pair into separate columns in the listview, loop through arrFirst, split each line on "|" and assign the result to .Text = arrSecond(0) .SubItem(1) = arrSecond(1)

I keep on getting runtime error 9, out of subscript, i think whats happeneing is its running through the loop one more time than it should, hard to explain but i can't seem to fit a condition in to stop the loop at a certain length.

Anybody know of any code that would fit this situation, it has to be able to parse a string with 2 delims and populate the listview with the filename in one columm and the respective filesize in the other.


my string is in the form,

VB Code:

....test.exe|6327,text2.exe|4776,test3.exe....and on|

Do you have to put them in columns? Can you just put them as subitems of listview items and use HitTest to get their values?

Use Replace first

c:\file1.exe|34502,c:\file2.exe|31233..etc.

Replace either the | with , or vice versa so the delimter is the same. Then Split it into an Array.

And step through the loop in 2s instead of the default 1 ;)

I got it, thanks.

One more thing, the scrollbar doesn't appear in the listview when the list exceeds the height. I am using this(below), to auto resize the listview and treeview if that makes a difference,

VB Code:

Public Sub Form_Resize()
 
     lvFiles.Width = Me.Width
    lvFiles.Height = Me.Height
    TvTreeView.Height = Me.Height
 
End Sub

In fact it doesnt appear even if i don't resize. :confused:

Anybody know how to get the vertical and idealy horizontal scrollbar to appear in my listview, it doesn't by default and there doesn't seem to be an option to add one in the properties ?

:confused:

I am really curious...never seen the listview do this - is it possible for you to upload your project?

If your Listview and Treeview controls are side by side on the Form, then the width of the Listview should take into account the width of the Treeview.

I think the listview is extending off the form, the scrollbars are offscreen.

This assumes the Treeview is on the left side and Listview is on the right.

VB Code:

Public Sub Form_Resize()
    If WindowState <> vbMinimized then
        If Me.ScaleWidth > tvTreeview.Width + 100 'otherwise an error if the form is resized smaller than the width of the treeview
           lvFiles.Width = Me.ScaleWidth - tvTreeview.Width
        End If 
        lvFiles.Height = Me.ScaleHeight
       TvTreeView.Height = Me.ScaleHeight  
    End If 
End Sub

Use the ScaleWidth and ScaleHeight properties of the Form instead. They represent the client area of the form. I.E. they do not include the title bar , borders, menus etc..

Ok thanks thats what i thought might be happening but i've just taken the form resize out and still no scrollbar, shouldn't the scrollbar appear automatically ?
