"If" not firing, what am i missing?

[MichaelTJ]

for i = 0 to 8
If "Label" & (((i * 2) + i) + 2) & ".Text" = "M" Then


according to the "Global variables" panel bottom center, the value of Label2.text and Label5.text are both equal to "M" however, the above "If" does not fire

i assume i am staring right past something obvious

"&" is a string concatenation operator, you want "AND"

 

[MichaelTJ]

using "AND" in place of "&" causes "Cannot parse: Label as bollean"
i so wish the "If" statement to evaluate the "Label2.Text" and "Label5.text" labels

 

[MichaelTJ]

perhaps not possible?

i thought i had done something like this previously but upon checking discovered that i had not..... perhaps cone cannot assemble the label"Label5.text" so that it can be evaluated as i have attempted to do.... i'd love to be contradicted on this

You can't access a view name through a string like that, you'll need to store the Label references in an array of Labels

Dim LabelArr() As Label

You can add them when creating them in code, or if created in the designer, like this:

LabelArr=Array As Label(Label0,Label1,Label2,Label3)

then you can do:

If LabelArr(((i * 2) + i) + 2).Text = "M" Then

If you need to reference views with a string then you should use a Map:

Dim MapOfViews
...
MapOfViews.Initalize
MapOfViews.Put("Button1", Button1)
MapOfViews.Put("Label1", Label1)

...
Dim lbl As Label = MapOfViews("Label" & 1)

A Map, very clever. That's another good thing about b4a, never say never! you get lots of choices.
