Did you put files in their appropriate folders?

i put only here

you have to put the png file in the "res" folder
and you must declare MIDlets in the project before you attempt to compile it

@ComputerJy

you mean all midlet?

You only have 1 midlet which is the class that extends MIDlet (indearcalc)

I've attached a zip file that contains the project folder, copy it into the wtk\apps and open it from the KToolbar.

Take a look at the settings, if you have other questions don't be shy to ask

it is possible to change the name instead of (indearcalc) ?

br
:)

It's doable, you'll need to change the class name and the filename, then change it from the settings

Hi, i already done it..

i tried compiling this code but no success? could you make also sample for this?

Instead of creating a new midlet app I added this MIDlet to the previous MIDlet suite.

how did you do that? ;) i tried to install it on my phone it works perpectly.. on Master Code can we put also a ticker banner?

thanks

br

You can't keep doing this forever. You must learn how to modify the settings, and it's very easy to add a ticker
