Only own class private members i.e. a method (private or not) in a class is able to access private members of the same class through a reference (of the same class).

It's pretty much the same. It's just that the namespaces in VB6 coincide with projects i.e. in a project you have only one namespace which is named exactly like your project.

This is a cool piece of technology you have here.

MOVSD is like MOVSB but works on dwords. Both "move" data from ESI to EDI -- there are no registers involved except ECX which is decremented by one i.e. for MOVSD the initial ECX is number of...

Besides MOVSB there are MOSVW (16-bit word transfers) and MOSVD (32-bit dword transfers) but yet faster would be to use MOVDQA i.e. SSE instruction to load 128-bit registers which can be done in...

Btw, it's a one time edit in your .vbp file. (You don't have to "remember" about it once it's edited.)

You don't need an add-in for this if you are willing to one time manually edit your .vbp file and copy/paste these two lines of undocumented LinkSwitches.

First, you have to learn how to work with byte-arrays in crypto. Your "238dbd3bd53ee4c53c505ca2b56e1756e622aa0c" is a *string* literal -- so called hex dump of a byte-array. You need helper functions...

It was a certain Win 10 update which *revealed* the problem.

I mean the dormant issue must have been there all along but did not cause any issues with previous OS versions.

Usually it's when you append to an dynamic array you just check size and resize if needed and then assign last element If lSize > UBound(arr) Then ReDim Preserve arr(0 To lSize * 2) End If :...

Try to follow this with


ReDim Preserve u(0 To 10) As MyUdt
u(0).i = 42

Second line assignment fails with resized UDT arrays but works ok with arrays of scalar (primitive) types.
