VS 2005 Getting Out Of A Function?

Jun 28, 2010

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))

VS 2005 Run A Function In The Background?

May 17, 2010

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.

VS 2005 - Function Based On Timer?

Feb 9, 2010

I can't seem to get one of my functions to work based on a timer. Every tick of the timer, I'm trying to call a function which will start periodically taking screen shots until the 'Finish' button is pressed. However, I've run into numerous errors and wondered if anyone could give me any insight or suggestions. Here is what I have so far.

[Code]...

One of the errors included "Public Sub RunAC() does not have the same signature as delegate". This might be really obvious, I'm a recent Computer Programmer / Analyst graduate with intermediate VB.net experience.

[2005] Is An Obejct Returned By A Function By Ref?

Feb 25, 2009

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

VS 2005 Function Return Types And Error Conditions

Jun 8, 2012

Lets say I click a button on a form that calls a function in a data access class. This function inserts a record into a table in a database. The function returns an integer value for the record id of the newly inserted record. Now lets say the insert failed (syntax error, timeout, whatever). I can return a zero to the calling routine to indicate the failure, but not the error message. So in general, what's the most appropriate way to handle getting information back to a calling routine when the return parameter data type doesn't allow it?

VS 2005 Tree View Full Path Function Gives Invalid String

Oct 3, 2009

I thought I was done with the tree view control until i realised that my tree view control was behaving differently when it came to sub nodes . I have attached my treeview pic and also a sample tree view.

(-)D:
|_config.msi
|_netfile.sys

[Code]....

Since I clicked on subfolder1 i was expecting the msgbox to display D:Folder1Subfolder1 but unfortunately the msg box doesnto even have the name of the node i clicked on but when i use selectednode.text I get the correct node text. Anyways why isnt my full path working. I then tried manually designing the entire scenario using tree node editor and the code which i mentioned above works. But whenever i populate the trr programatically the above problem starts.
