There is not more information, I just want to disable one of the buttons based on some logic. I understand validation but that's not what I'm referring to.
Smal question about IsValid event. I want to do a httpjob to validate. However, this can only work when using Resumablesub in the http sub that I use. This however does not work with the IsValid event because it needs to be a Boolean while B4A asks me to change it to Resumablesub.
All should happen when the dialog is open. Otherwise I have to open and close the dialog all the time when a value is not valid.
Sub Button1_Click
Wait For(Sum(1, 2)) Complete (Result As Int)
Log("result: " & Result)
Log("after sum")
End Sub
Sub Sum(a As Int, b As Int) As ResumableSub
Sleep(100)
Log(a + b)
Return a + b
End Sub
