Changing label text programmatically

[William Hunter]

I am trying to change label text programmatically. The label has been declared in Globals and initiated in Activity_Create. The code for the text change is in another sub. I have been able to make similar text changes with buttons, but can’t seem to do this with labels.

Any help would be appreciated. :sign0085:

To change the text of a label:

Label1.Text = "Some Text"

Maybe there's something else in your code, but without seeing it is just a guessing game.

It's the same as with Buttons.
Label1.Text = somestringvariable or
Label1.Text = "some text".
If the label is defined in a layout file you must NOT initialize it in Activity_Create !
Otherwise you are initiating a new instance and have no acces to the one difined in the layout file.

Best regards.

To change the label text it is just

lb.Text = "One"

this can be done in the labels activity but not from another module.

Thank you all for your response. Klaus correctly identified my error. I had initialized in Activity_Create. :signOops: All is now well.

why do i then get this as error:

Error description: Undeclared variable 'Label1' is used before it was assigned any value.

You don't give enough information !
Where and how do you define Label1 ?
- in a layout file ?
- in the code ?
Do you Dim Label1 As Label in the Globals routine ?

Best regards.

Hi, if I would like to have certain output (which is a combination of variables and text) from the label such as : 'result.Text = "Your annual return in % is: " annualReturn " and your investment will be returned in "years" years."'.
How do I correctly concatenate the variables' value with the text?? Help is appreciated

Are you meaning this?

result.Text = "Your annual return in % is: " & annualReturn &" and your investment will be returned in " &years &" years."'.
