Re: When to use Integer and when not to
Show me one example where, in 32-bit code, an integer takes 64 bits. Got it the 'wrong way around' as seems to be 'on purpose' always (and, definitely NOT funny!). What does your confused code have to do with the OP's statement "an Integer is but a 64 bit field of which only 32 bits can be use...

The wording is pretty clear - and he is wrong. There is no "64-bit field", and there is no waste of memory. In 32-bit code, an integer uses 32 bits of memory, fullstop.xlucas wrote:a 64 bit field of which only 32 bits can be used, that is, a waste of memory

Re: When to use Integer and when not to
That's funny - who invented this integer<32> stuff? Why not long<32> or long32 or short<32>? Why is there no ptrsize (which would actually be useful)? Oops, I see that Print sizeof(any ptr), "ptr" works... Print sizeof(short), "short" Print sizeof(integer), "integer" Pr...

Re: When to use Integer and when not to
The problem arose in the moment when somebody decided to call 64-bit variables in 64-bit code "integer", contrary to most other languages. It's a big ugly mess, though - and not only in FB - see this Wikipedia article. And this is just plain wrong:caseih wrote:So perhaps he's correct and we should be urging FB programmers to stop using Integer.
Sorry to be rude, xlucas, but before posting something you should make an effort to understand and prove your case.xlucas wrote:an Integer is but a 64 bit field of which only 32 bits can be used, that is, a waste of memory

Re: When to use Integer and when not to
In most practical aspects, an Integer is but a 64 bit field of which only 32 bits can be used, that is, a waste of memory Is it, really? Dim MyHex1 As integer=&H1234ABCD, MyHex2 As integer=&H12345678, MyHex3 As integer=&H33333333 asm lea eax, [MyHex1] lea edx, [MyHex2] lea ecx, [MyHex3]...

Re: Split 8bit in 4bit
Not everyone. It does occur to me that when putting this into a macro for convenience, since there's no type associated with the macro, the initial masking with &hF0 (or masking to &h0F after the shift) ensures that the macro works with any size of numeric type Show me a type where masking ...

Re: Antivirus hurt by functions pasting text on clipboard - sometimes
The code was for text (ansi) - jj2007 For unicode this is better. Your code works fine, but too much acrobatics for my basic taste. My snippet above works fine, too, if you put 2*Len+2. The point is another one: You tell the compiler "it's unicode" with #Define UNICODE. Fine, so the compi...
