checking textbox string

[derez]

Hi
I am puzzled by an inconsistency between the device and the desktop.
I attach a small program to demonstrae it.
when pressing the button, I check a textbox text if it is empty and if yes - put minus, else plus:

If textbox1.Text = "" Then textbox1.Text = "-" Else textbox1.Text = "+"

when run on desktop it works, on the device I always get +

Hm ... your code works fine on my wm5 device ...
Are you sure you haven't got a space as a default value for the textbox on the device?

I've checked it also and it works fine.

[agraham]

Fine for me also!

[derez]

Must be something wrong in my installed Basic4ppc.
I was confronted with the problem in an application that I work on, and built this small program to check it, and in both the same problem.

Anyway, I went around it with a flag instead of checking the textbox.

Thanks to all of you.

Hi,

What about StrLength(textbox1.Text)?

[derez]

Dzt

Of course this looks as a nice go-around, but amazingly it doesn't work.
I modified the test program, the sequence that should be written in the textbox is "-+++" using either button.
This is ok on the desktop but on the device - nothing is written !
I checked it on another MIO350 - the same result.

I don't see this problem when I test it.
Please add:
Msgbox(StrLength(textbox1.Text))
before the condition statement and check the initial value.

Very strange.
Try also at App_Start or somewhere else textbox1.text = ""

Erel - Your guess was right, the length is 1 !
I checked by ASC() and it is 0 (zero)

dzt - what you suggested did not change the situation

I checked the same code on a control button instead of textbox - it works fine.
