Android Question Must use DOEVENTS...

[Rusty]

I am using Reflection to measure a label text width.
If I don't put in a Doevents, (see below), the returned value is random or "previous" value from prior calls.
Is there a better (non-Doevents) way to get this to work consistently?
Thanks,
Rusty

The code is as below.

'MAIN inline code, Label1 is loaded in a .bal layout
    Type CameraSize (Width As Int, Height As Int)
...
            Label1.Text = "yes"
            Label1.TextSize = 14
            DoEvents                                       '<---<<< without this, it returns either "random" or previous values
            Dim tmpSize As CameraSize = Fn.GetLBLTextInfo(Label1)

'gets the text size of a label
'returns CameraSize (ENM) width and height type structure
Sub GetLBLTextInfo(lbl As Label) As CameraSize
    Dim tmpSize As CameraSize
    tmpSize.Initialize
    Dim TMS2 As Reflector
    lbl.Width = -2
    lbl.Height = -2
    TMS2.Target = lbl
    tmpSize.Width = TMS2.RunMethod("getWidth")
    tmpSize.Height = TMS2.RunMethod("getHeight")
    Return tmpSize
End Sub

Have you tried to use this?

Sleep(0)

Thanks for the suggestion, but Sleep(0) doesn't work.
In fact, without an error (I tried Try/Catch) it exits my routine immediately and does not continue past that line.
(In my code snippet in post #1 the Doevents is changed to Sleep(0) and no line below the Doevents ever fires...)

That's the expected behavior when you call Sleep or Wait For.

It will however resume shortly after.

Post the complete code with Sleep and I'll help you fix it.
