create variable and assign sequential values using ilogic inventor

Hello!

I'm trying to do this operation below using ilogic inventor, but it doesn't work. Basically create the variables F1, F2, F3 and F4 and then assign the values 1, 2, 3 and 4 or 0. Any help is welcome.

i = 0
While i<4
	i = i + 1
	oxyfuel= "oxyfuel_F" & i
	If Feature.IsActive(oxyfuel) Then
		"F" & i = i
	Else
		"F" & i = 0
	End If
End While

MessageBox.Show("CF" & F1 & F2 & F3 & F4, "Part name")

Hi @luis_sanderKNSGP. I am not sure what all you were trying to achieve there, but below is my interpretation of what you wanted to achieve. You can not 'declare' or 'define' a variable by concatenating its name together like a String. The result of that is just a String, not a variable for representing a value. So, I 'declared' those F# variables before the loop, then set their values within the loop, so that the message outside the loop will recognize them.

Dim i As Integer = 0 Dim F1, F2, F3, F4 As Integer While i <= 4 i += 1 Dim oxyfuel As String = "oxyfuel_F" & i If Feature.IsActive(oxyfuel) Then If i = 1 Then F1 = i ElseIf i = 2 Then F2 = i ElseIf 1 = 3 Then F3 = i ElseIf i = 4 Then F4 = i End If Else If i = 1 Then F1 = 0 ElseIf i = 2 Then F2 = 0 ElseIf 1 = 3 Then F3 = 0 ElseIf i = 4 Then F4 = 0 End If End If End While MessageBox.Show("CF" & F1 & F2 & F3 & F4, "Part name")

Hi WCrihfield, thank you so much.

This code performs what I need. However, the idea was to "create" the F1, F2... Fn. For example, if it were necessary to use "n" numbers of "F." Depending on the condition, this "F" should store the value of i or 0.

OK. Well, since we can't do that with actual variables, we could likely achieve similar functionality with some sort of collection type object, such as an Array of Integer, or List(Of Integer), or similar. Both of those vb.net based collection types start at zero though, not one, like most types of collections based in vb.net. On the flip side, most collection types that are defined within the Inventor API or iLogic API start at one, instead of zero, to make them more 'natural' feeling to work with.

Below is another example you can play around with. It is using a simple Array of Integers, with zero as the starting value. That way, we do not even need the 'Else' side of the If statement. Then, within the loop, and within the If statement, it specified the element within the Array by the current value of 'i' minus one, since the array starts at zero, and changes the value of that element to the current value of 'i'. After the iteration, we can either just use that Array variable directly within your message, or we can extract the individual Array values to static variables first, then use those variables within the message. Just another thought to reduce required code while maintaining similar functionality.

Dim i As Integer = 0 Dim oResults() As Integer = {0,0,0,0} While i <= 4 i += 1 Dim oxyfuel As String = "oxyfuel_F" & i If Feature.IsActive(oxyfuel) Then 'i-1, because Array's start at zero, not one oResults(i - 1) = i End If End While MessageBox.Show("CF" & oResults(0) & oResults(1) & oResults(2) & oResults(3), "Part name")
