Hi,
I noticed that if I assigned a different Event Name from the default (say ImageView14), it does not load the image. When run, it will prompt a message to initialise.

Does not work...
Img14.Bitmap = LoadBitmap(File.DirAssets,"s" & tmpImage1 & ".png")

Works...
ImageView14.Bitmap = LoadBitmap(File.DirAssets,"s" & tmpImage1 & ".png")

I also noticed that the filename has to be lowercase. Below statement will not work if I specify filename as "S"...

ImageView14.Bitmap = LoadBitmap(File.DirAssets,"S" & nI & ".png")

I have to change the filename to "s" and rename the actual image filename accordingly.

I remembered accessing my sql database file as well. Initially I set it to Project.db but it doesn't load. But when I renamed my db file as project.db and load it accordingly, it works.

Anyone else experienced this symptom?

That's normal. You change the EventName not the view's name.
To change parameters, like a Bitmap, you must use the view's name.

Changing the EventName is useful when you want to wire events of several views to a same routine.
You can have a look here: http://www.b4x.com/forum/beta/6518-addevent-sender-etc.html
