progressbar1.progress ............does not work

if i write it as = x ................error
if i leave it alone also error ??
in site documentation...it sets or gets the progress value

 

[IslamQabel]

i want just simple example or tutorial to be familiar with the library

 

[IslamQabel]

how to change the color and insert an image instead of the default tube background?

 

[Jeffrey Cameron]

The default progress bar will only render the "system default" appearance for the progress bar. If you want something more complex you will need to make your own control/view.

For an example of how to do something such as that, see this thread: LED bar VU meter

there some commands in default libaray, like
SetBackgroundImage (Bitmap As android.graphics.Bitmap) As BitmapDrawable
SetColorAnimated (Duration As Int, FromColor As Int, ToColor As Int)

are these commands not working?

you probably did not understand , you have a version too old and many keyword do not exist.
Sleep Animated etc ...

You should buy a newer version (now 8.30+) to use the potential of B4A


If you want to use an older version of older libraries with few functions
Use the bold as you did

i understand that i am using an old version, but i am just trying to build a quick solution with my very limited old version but soon i will buy the newest one

But i will ask if the new version will deal with my old codes or will cause some conflict as happens before with version V5 when i was compiling codes written by V4.3 and some error messages displayed.....so that issue make me hesitating if i upgrade to the V 8.3 , i am afraid that new version displays errors

anyway thanks for help

With the new version you can use the latest examples and then you can update your code and get assistance.

Anyway if you use the native ProgressBar, even if less powerful, but it also works in the dated versions of B4A.
If you need an advanced ProgressBar then you must necessarily use a more recent version.

Here is a thread about changing color of the standard progress bar which probably should work with older versions of B4A too.
Anyway, you really should upgrade.

You could always make a very simple progressbar with a label and filling it up with for example the | character in the loop.
