B4JSnippetCRC

CRC32

This might be useful to someone - and perhaps there''s a better way?? I knocked this out a while back because I needed to calculate a reliable CRC32. I got the algorithm from somewhere online but I''ve since lost the link :( I wrote it as a class (but it can easily be converted to a code module). Just initialize the class and then call Calc() - passing in the byte array. It will return an INT which is the CRC32. Note: the code is quick when run in Release but in Debug it can run quite slow (depending on the size of the array that the CRC32 is being calculated for) I should also mention that this works equally as well with B4A - not sure about B4i/R as yet. Maybe someone could comment if it works ok for those two IDEs ;)

B4JLibraryTabPane

MultiRow TabPane

Here''s something I needed and thought I''d share. Based on a FlowPane and A StackPane (minimal wraps for these and ToggleGroup are included in the source code). Implemented as a customview, buttons can be at the Top or Bottom.
