My first program in VB

But u can still tell me what's the use of different procedures; which we get when we click any of the controls?
I mean are they private? or public? Are they excluded from other code?
What if we dont make them?

This feature makes the task of developers easier.If you dont want to write anything inside the created procedure,just leave it or if you still feel annoying delete it.(Try not to double click any of the unnecessary controls in design time).

Since you are a beginner,you may feel this annoying,but once you get involved with visual basic,you'd really love this feature-it saves your time!

Remember visual basic does an event driven programming.

Public Sub Text1_Change()
Static inno As Integer
inno = Text1.Text
End Sub

Public Sub Text2_Change()
Static outno As Integer
outno = Text2.Text
End Sub

Public Sub Command1_Click()

If Option1.Value = True And Option4.Value = True Then
outno = inno
End If

End Sub

But m not sure whether i understand the meaning of event driven programming.

This kind of programming is event driven programming.

also you are declaring the integers whenever you call the text change subs which does not look correct

i think if i understand what you are trying to do you will need to have something like -

Public Sub Command1_Click()

If Option1.Value = True And Option4.Value = True Then
outno = inno
End If
Text2_Change()

End Sub

Why use static variables and declare it inside text box change event?instead you can declare variables generally(outside all events-so that the variables become public to the entire form)

For all the text boxes, options, variables no value is getting displayed other than the message: expression not defined in context for inno and for rest ; out of context..
Why is it so?

Better have a command button so that the user may click it after entering the number in the text box and selecting the conversion type option button. Finally include text2.text=outno in command button's click event.

Okay..just give me some time and i'll design the proj and attach it.

May be because m new in VB, i didnt understand why do i hav to keep it blank the text2 event?
And wats wrong with integer?
I mean earlier i had used string and instead of text i had used text1.text but i was getting a error that i cannot assign it to an array... M not sure wether i got that.

but the problem is i dont know how to attach it here..
anyone knows how??

Moreover i never asked for design..... M just gettin stuck somewhere in my code..

you seem to be accessing inno as an array ie: array(no of item)

if you are trying to select as specific character within the string / integer you will be better using the MID command I think

lol please bear in mind that there may be better ways of doing this and I have not tried to work out the conversion but here is some code to split the string

But now can someone tell me how we use not equal to sign in VB?

I got that to by writting the expression in'( )' and using <> sign; but now m not getting equal to sign.

The compiler is showing error.
Is it the wrong way or sth else..
