Well a function is a special type of procedure that returns a value each time it is called. A function is generally used to perform a particular task/s repeatedly when needed. Visual basic provides several built-in functions as part of the programming language, such as MsgBox, Round and so on. We can also create our functions which does a user defined task. We can pass arguments to that function and return a value also based on the parameters. There are 4 types of functions in Visual Basic and they are as follows Continue reading ‘Beginner’s Guide to Visual Basic 6 – Part 2′

So this is tutorial is first of the series that I am writing. Now I will go for some bookish definition of VB.

Updating Items in Collection

I have been working with collections for sometime now, i had always either deleted or added item in the collection but never updated. Today i had a need to do that, when i searched i couldn’t find a direct method to get a item in a collection updated. After some confusing moments i ended up the following code

Dim t As New Collection
Dim iRemove As Integer
Dim iCnt As Integer
 
iRemove = 3
t.Add ("te")
t.Add ("ew")
t.Add ("Ad")
t.Add ("Adtree")
t.Add ("tewww")
MsgBox t(iRemove)
Call t.Add("Ads", , IIf(iRemove = t.Count, iRemove, iRemove + 1))
For iCnt = 1 To t.Count
Debug.Print t(iCnt)
Next
t.Remove (IIf(iRemove + 1 = t.Count, iRemove + 1, iRemove))
MsgBox t(iRemove)
 
For iCnt = 1 To t.Count
Debug.Print t(iCnt)
Next

Nothing too fancy in that code, so far it has worked fine but will wait till i implement it in the main code to celebrate ;-) :D . On another note, i have been reviewing UCertify’s PrepEngine, I must say it’s pretty darn good. Soon, in couple of days, you see a full review of their product in my blog.
