But whenever i populate the trr programatically the above problem starts.

Some programs implement command parameters, Like my favourite computer game - Crysis - has them and windows media player has them.But how could i implement them in VB.NET..I want to have a component of my program built as a seperate exe - so it can be an Optional component.But of course the seperate exe, on load, needs data passing to it.So i need something like Process.start("Componentname.exe", "/StartDL <Suchandsuchastring>)/StartDL will need to call a function, and the string that it uses will be given to the function to initiate a download?
View 9 RepliesThe following output produces a string with no closing xml tag. m_rFlight.Layout = m_rFlight.Layout + "<G3Grid:Spots>" + Me.gvwSpots.LayoutToString() + "</G3Grid:Spots>"
This following code works correctly
m_rFlight.Layout = m_rFlight.Layout + "<G3Grid:Spots>" + Me.gvwSpots.LayoutToString()
m_rFlight.Layout = m_rFlight.Layout + "</G3Grid:Spots>" 'add closing tag
What's going on here, what's the reason the first example isnt working and the second is?
The gvwSpots.LayoutToString() function returns a string.

Is 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))
codes like(x is variable)
dim k as string="5b5" & x & "85"
I want to know how many times "5" appears in k,

I 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.
I have few columns in a datagridview,out of which one is of type Button and another is of TextBox(which is hidden). When the user clicks on the button in the column , i want to execute the function whose name is written in the corresponding column.

I 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
public function cloneGBox (byval x as integer, byval y as integer) as groupbox
