VS 2005 Getting Out Of A Function?
Jun 28, 2010Is this a good way of getting out of a function?
If f1.AppendLine(strTextMsg, strText) = True Then
Return True
Exit Function
Else
Return False
Exit Function
End If
This is in code that I'm taking over and finishing and I'm just wondering if I should be skeptical of this logic. The programmer seemed to overly-use "Exit Function" (like right before an exception handler would be called as if he thought if he didn't have it he'd fall right through into the exception handler even when there was no exception).
Personally, I would've just coded: Return(f1.AppendLine(strTextMsg, strText))

VS 2005 Run A Function In The Background?
May 17, 2010I have a datagrid with a list of items. Each item has an url for a picture. For each item I have to download the picture from the url, and then show it in the grid. This takes quite a long time, and freezes my application while running.
Is it possible to do this in the background, while allowing the user to take other actions? For example, scrolling down the list to see the items that have been loaded. Or clicking on an item in the list, which calls another function. Maybe doing something on a different form. And doing this while the list continues to load in the background.

[2005] Is An Obejct Returned By A Function By Ref?
Feb 25, 2009I have a 2 dimensional array of groupboxes that I use to populate a form setup so the first indice is a tab number and the second is the groupbox number.The user can dynamically add tabs to the tabcontrol but I need to add and populate groupboxes to the new tabpage and I can use existing groupbox data in the array for default values.I understand I have to code a deep clone of the source groupbox as it has textboxes in it so I want to add a cloneGBox function that returns a new, populated groupbox when I pass in the x,y indices for the source groupbox in my array.
dim gbx as groupbox = cloneGBox(x,y)
and code cloneGBX as
