Thanks Christian. Since 'r' is going to be modified by the algorithm,
shouldn't the entry be "ByRef r As MemoryBlock"? Also, am I using the
correct identifier for this type of function (accept 3 memoryblocks,
modify the contents of the 3rd) when I use "REALNoImplementation"?
Let me see if I understand how this *should* work:
The change above works and my ModularExp() method nows autocompletes in
the IDE editor - however, the helper text does not show up in the IDE's
status bar.
When I run my code in a pushbutton's action event - a simple creation:
Dim m1 As New MemoryBlock(64*2) // 64 shorts
Dim m2 As New MemoryBlock(64*2)
Dim r As New MemoryBlock(64*2)
Dim x As Integer
For x = 0 to 63
m1.UShort(x * 2) = &hffff
m2.UShort(x * 2) = &h0000 // just to make sure
r.UShort(x * 2) = &h0000
Next
m2.UShort(0) = &h5 // run the reduction loop 5 times
ModularExp(m1, m2, r)
I get a hard crash. My first thought was that I needed to pass result
as ByRef (the contents of result() are changed to contain the result),
but I get the same error.
If I take the Plugin back to a standalone tool, the compiled app runs
with no errors.
Any thoughts or guidance on how to troubleshoot / debug this?
Tim
