[RESOLVED] CopyMemory Shift Array one position

[Jonney]

I've not used VB6 in a while but...

It looks to me like you are just copying the safearray pointers rather than the data.

If any of these are lost as a result of the copymemory call (eg. #999) I think you will get a leak. Manually deallocate any of these before the call to copymemory (Erase m_CellRows(999)).

The copymemory call from the example will also create a second reference to array #2. After the call I think the original needs to be deallocated using copymemory or similar to avoid the garbage collection running twice on the same object (something like CopyMemory ByVal VarPtr(m_CellRows(2)), 0, 4)

Thank you,Milk. It needs CopyMemory ByVal VarPtr(m_CellRows(2)), 0, 4 to do garbage clean. After I put this, the data looks OK. Without this, the data got mad even though no crash.

Thanks Bonnie West.
