In Part 1 we touched the basic’s, now we will move to the next step.
System Defined Functions: Now the second chapter, we will deal first with some of the system-defined functions in vb. What is this “function” ? 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′
I’ve seen couple of posts in the site where people have like asked the basic questions about VB. For instance, is there a need to declare a variable and what is the use of a module and so on. So this is tutorial is first of the series that I am writing. Now I will go for some bookish definition of VB.

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
Call t.Add("Ads", , IIf(iRemove = t.Count, iRemove, iRemove + 1))
For iCnt = 1 To t.Count
t.Remove (IIf(iRemove + 1 = t.Count, iRemove + 1, iRemove))
For iCnt = 1 To t.Count
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 . 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.
