Things that worked before rev. 1184

[Stoner]

I now am trying to do this also, and it appears even Atoms sample code is breaking.

buf = MemoryBlock( 4, true ) gives an No matching overload found error.

yet

buf = MemoryBlock()

l = buf:getSize() yields an error Trying to use unregistered class.

 

As I can not ever use getSize() on a MemoryBlock I have no idea whether file.loadFileAsData( buf )  is working.  It returns a true but I am unable to use buf:getSize() to test the return size.

 

Help.

Ahhh a reminder, on it.

Ok so it should work now (without the size parameter i just added that), here is an example (the MemoryBlock constructor from an array of bytes is also just added, but you can create it other ways)

mb1 = MemoryBlock ({0x01, 0x02, 0x03, 0x04})
mb2 = MemoryBlock ({0xa1, 0xa2, 0xa3, 0xa4}) -- The first two constructors take an array of bytes
mb3 = MemoryBlock ("b1 b2 b3 b4") -- This is a constructor that takes a string

mb1:insert(mb2,2) -- this should work now
console ("mb1:"..mb1:toHexString(1))

mb3:insert(mb2, 1, 1) -- this method is new, it will be available in the next nightly
console ("mb3:"..mb3:toHexString(1))

Output will be:

mb1:01 02 a1 a2 a3 a4 03 04
mb3:b1 a1 b2 b3 b4

[atom]

mb1 = MemoryBlock() -- this is available now
mb2 = MemoryBlock(4,true) -- this is available now
mb3 = MemoryBlock(mb2) -- this is available now
mb4 = MemoryBlock ("ab cd") -- this is new
mb5 = MemoryBlock ({0xab, 0xac}) -- this is new

A new nightly will have all the constructors.

Okay, thanks, but still missed the Trying to use unregistered class error on MB:getSize() of a MemoryBlock.

OK try 1267 now if you already downloaded it, please download it again.

No still a problem Atom.  Here is what I am doing and I need to get from start to finish and actually send some data.  You will need to create a valid File(“ValidSysEx.syx”) called lastFile.

 

data = MemoryBlock()
len = lastFile:getSize()
if lastFile:existsAsFile() and len > 2 then
if lastFile:loadFileAsData( data ) and len == data:getSize() then
if data:getByte(0) == 0xf0 and data:getByte( len-1 ) == 0xf7 then
midi = CtrlrMidiMessage( data )
panel:sendMidiMessageNow(midi)
utils.infoWindow(“Send SysEx File successful!”, “File sent: “..lastFile:getFullPathName())
else
utils.warnWindow(“Send SysEx File failed!”, “File was not SysEx file: “..lastFile:getFullPathName())
end
else
utils.warnWindow(“Send SysEx File failed!”, “File did not load correctly: “..lastFile:getFullPathName())
end
else
utils.warnWindow(“Send SysEx File failed!”, “File was too small: “..lastFile:getFullPathName())
end

I can confirm that if I remove the compare on the length above I will get a midi message and it’s type will return as 5, which is correct but midi:getSize will return 0 (zero) which should be 7 in my case and no midi data will be sent.

I’m posting a fix right now.

Hi atom,
found this old post…

Retested mb2 = MemoryBlock(4,true) from above
and I get errors (5.3.201)

ERROR: No matching overload found, candidates:
void __init(luabind::argument const&,String const&)
void __init(luabind::argument const&,luabind::object const&)
void __init(luabind::argument const&,JMemoryBlock const&)
void __init(luabind::argument const&,custom [unsigned __int64] const,bool)
void __init(luabind::argument const&)

Thx to have a look!
