How to Force vertical scroll in GuiCtrlCreateListView

[ToyleY]

Is it possible to force a vertical scroll bar in GuiCtrlCreateListView?

I have tried $WS_VSCROLL (general style) but the scroll bar does not show up (if list is too short)

The line below does not show a scroll bar?

GuiCtrlCreateListView("Date|time", 127, 69, 400, 228, $WS_VSCROLL)

And ideas please?

Windows scroll bars don't appear unless there is something to scroll, otherwise you would have a bar which you couldn't move so what would be the point of showing it.

Thanks but .....

There is $LBS_DISABLENOSCROLL Shows a disabled vertical scroll bar for the list box when the box does not contain enough items to scroll. If you do not specify this style, the scroll bar is hidden when the list box does not contain enough items.

It's a right mess if I can't force a vertical scroll bar.

That's interesting, I didn't know about that.

LBS_DISABLENOSCROLL (Windows Version 3.1 or Later)

The LBS_DISABLENOSCROLL style causes the list box to disable any scroll bar that is not needed because the current contents fit the list box. Normally, when a list box scroll bar is not needed, it is hidden. The LBS_DISABLENOSCROLL style must be used in conjunction with the WS_VSCROLL or WS_HSCROLL style.

So it should do what you want. I tried it and didn't get the disabled scroll bar. Have you got an example where it shows?

$LBS_DISABLENOSCROLL does not work with GuiCtrlCreateListView

I've given up with it. I'm now using $LVM_SETCOLUMNWIDTH, with a test of how many are in the list (so I can set the columns to ether the full extent or shorter, to accommodate a vertical scroll bar [when it appears] -- so I don't get an unwanted horizontal scroll bar and/or messed up grid lines).

It's a lot of work for a simple thing.

Ta anyways.

If you just want to redraw the listview to get rid of the messed up grid lines then you can do this

DllCall("user32.dll", "int", "InvalidateRect", "hwnd", GUICtrlGetHandle($ListView), "int", 0, "int", 1)

It might be simpler if it works for your script.

LBS_DISABLENOSCROLL => LB = ListBox not LV = ListView

Not interchangeable
