filelistbox integral height

[UKDavid]

Is there any way to turn OFF integral height on a filelistbox?

Because it is on the control size 'jumps' when the form is resized, which looks poor...

Thanks in advance!

I don't understand, sorry.
What is the integral height? When does it jump?

Can you elaborate more please UKDavid. When I put a FileListBox on my Form and resize the form, I don't see anything weird ¿

The FileListBox, much like the Listbox only resizes to specific sizes based upon the font size of the control in question so it does not automatically show the upper half of an entry whilst hiding the bottom part of the text under the 3d border of the control. This is the integral height the OP is talking about and while the standard listbox has this property (t/f), the FileListBox does not have this property.

As for solving this, use a standard listbox and populate it from a hidden FileListBox or...

Option Explicit

Private Const LB_ADDFILE = &H196
Private Const LB_DIR = &H18D

Private Const DDL_ARCHIVE = &H20
Private Const DDL_HIDDEN = &H2
Private Const DDL_READONLY = &H1
Private Const DDL_DRIVES = &H4000
Private Const DDL_DIRECTORY = &H10
Private Const DDL_EXCLUSIVE = &H8000

Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Any) As Long

Private Sub Command1_Click()
SendMessage List1.hwnd, LB_DIR, DDL_EXCLUSIVE Or DDL_ARCHIVE Or DDL_HIDDEN Or DDL_READONLY, ByVal "E:\*.*"
End Sub

Good Luck

Brilliant stuff vb5prgrmr!

[UKDavid]

vb5prgrmr's explanation is exactly what I meant

Thanks all for looking and especially to vb5prgrmr for his solution.

[vb5prgrmr]

Thanks to the both of you, but now if you don't mind Dave (Good Morning Dave ), could you please use the thread tools and mark this thread as resolved.



Thanks once again

Very good. I didn't know about that integral height. Only I'm a little confused...

This is the integral height the OP is talking about and while the standard listbox has this property (t/f), the FileListBox does not have this property.

It must be the other way round, then. FileListBox HAS the integral height and ListBox has NOT. Or did I mistake that?

[vb5prgrmr]

No, I think I got it right. Just add the controls to the form and look at their properties...

Yep! The Listbox control (List1) does have this property listed but the FileListBox (File1) does not have this property listed in the properties list.

Now, how to see this in action...

Add a standard list box, text box, and file list box to a dummy form.

Click on the text box, hold the shift key down, and hold the down arrow key down for a second. You should see the text box change dimensions, specifically its height. (CTRL+Arrow key will move control around on form.).

Now do the same for the list box. You should not be able to change its height this way until you set its integralheight property to false.

Now, once you have resized the list box in this fashion, reset its integralheight to true and you will see that it changes dimension (height) to fit the closest size of x# of entries.

The filelistbox on the other hand does not have this property and to resize this control during runtime, you must either use the mouse or directly enter a value in the height property.


Hope that explains it a little better.



Good Luck

Ok. Understood now. I misunderstood the term "having the integral height property".
As it seems, both List- and FileListBox HAVE the integral height property, only the FileListBox does not expose it, so you can't turn it off.
