hi
i want to create new Measuring Unit from Main units (like : meter,kilo gram,...) by formula, for example i want to create new unit from this formula :
unit1 = (1.25 * Meter) / 100
or
unit2 = ((1.25 * Meter) / 100) + 91
but i don't know how to do, do i need Regex ? if yes, can u give me a useful articles or sources ?
thanks.

I have no idea where you expect to need regex here, do you want to pull numbers out of a string ? Do you want people to type in the formula ? In both those cases, yes, some form of string mashing is required. Is that what you meant ?

Hi! I want to know how can I copy item from one listview to another listview. Thanks ahead

ok..but If I have selected multiple items from the first listview...and then I want to put them all in the second list view...how I need to do that?
|
|
|
|

SelectedItems property returns all the items that are selected. You can iterate over them and copy one by one.

I know, I tried few times, but simply it doesn't want to move from one listview to another, I am trying something like this:
example:
listview2.items.add = listview1.selecteditems;
can you please give me some better way to solve this, it's really important for me...Thx ahead

ok...so this is how I did it, according to your advices:
List<listviewitem> NewList = new List<listviewitem>();
lvFiles.SelectedItems.CopyTo(NewList.ToArray(), 0);
lvAccepted.Items.AddRange(NewList.ToArray());
and I got ArgumentException at the second line:
"Destination array was not long enough. Check destIndex and length, and the array's lower bounds."
Any help??

|
|

Sure,
Here u GO :
List<ListViewItem> arr = new List<ListViewItem>(listView1.SelectedItems.Count);
foreach (ListViewItem LVI in listView1.SelectedItems)
{
arr.Add(LVI.Clone() as ListViewItem);
}
listView2.Items.AddRange(arr.ToArray());
this Works Fine, i've Check It

I have a collection class which wraps a generic List. This collection has two methods say, MoveUp and MoveDown. When MoveUp is called with an item, the supplied item will be moved one location down in the collection. There are events available for these operations.
I have a custom control which wraps ListBox. This control has subscribed for the events in my collection class. So when there is MoveUp or MoveDown in the collection, this control will get notifications.
Now I need to rearrange the listbox items according to the collection items when something moves up or down. I am doing this by removing all listbox items and adding it again which seems to be a bad idea and also it flickers the control.
Is there any better way to do this ?

What about swapping them?
Move up
Object o = lb1.items(lb1.selectedindex -1 )
lb1.items(lb1.selectedindex -1 ) = lb1.items(lb1.selectedindex)
lb1.items(lb1.selectedindex) = o
Obviously needs a bit of tinkering and checking for top/bottom, but you get the gist.

Remove the selected one, and re-insert it one position higher (don't forget to account for being at the top or bottom of the listbox). Also, you can avoid flickering if you turn off updates, remove/insert, and then turn updates back on.

Fair idea. Thanks John

I can't find how to turn off updates. Do you mean to calling SuspendLayout() and ResumeLayout() ?

It's actually BeginUpdate() and EndUpdate()...
