The off-line converter shown before was a code prototype.
From a design perspective one also needs to worry about what happens when
the user resizes the control. By default, a background image will be of fixed size.
Docking the background image will keep a larger one in place, showing more or less as
a function of the size requested but the controls themselves still need to
be placed unto something, like a layout panel.
The on-line converter below will not shrink smaller than the size of the browser on the bottom.
I have also placed the combo Boxes and buttons in a table, and they move as a block.
From a coding perspective, I have used the model from the You Tube tutorial cited
below.
One needs to be careful that the currencies requested will be recognized. Google
is the back-end here and a Canadian dollar is a CAD and a US dollar a USD etc...
