Re: Declaring & Variable already declared.. Message

Would something like this work for you:


CompilerIf #PB_Compiler_Processor = #PB_Processor_x86

If Is64bitOS() : Protected *Item = @ItemB.StructB : Else : Protected *Item = @ItemA.StructA : EndIf

CompilerElse
Protected *Item = @ItemA.StructA
CompilerEndIf



If it is memory space that you ...

Re: PB5.20 bug: 'Swap' does not swap pointers

I apologize ahead of time as I know this thread is old but I have two items, one that might help and the second item are some questions:

Here is my suggestion to do this using 64 bit registers and not the FPU:


Macro I_Swap(a,b) ; New Macro
!mov r8 ,qword[a_#a]
!mov r9 ,qword[a_#b]

Re: Bits manipulation

Demivec,

WOW, learn something new everyday!!!!

So..... What did I learn from this?

1. When using ASM the following must be used:
1.a. The nomenclature of '[v.<PB_VAR>] is used for variables defined/used in the main section of code (not in a procedure)
1.b. The nomenclature of '[p_v.<PB_VAR>] is ...

Re: Bits manipulation

Jassing,

The line of code '[p.v_#ByteTarget]' is not defining a constant but the nomenclature for how to use concatenation in a Macro ([p.v_#ByteTarget] turns in to [p.v_<PB Var>] instead of [p.v_ByteTarget]).
This is how you pass a PB variable to in-line assembler when using the ! directive ...

Re: Bits manipulation

First post in a long time!
I have an issue with trying to convert this code to use ASM in different fashion.
Probably due to something stupid I am doing (or not doing) BUT I can't see it.

Given the above code I have been trying to use the alternative calling nomenclature (code example below ...

Re: Bit reversal

From the Flat Assembler doc's:

bswap reverses the byte order of a 32-bit general register: bits 0 through 7 are swapped with bits 24 through 31, and bits 8 through 15 are swapped with bits 16 through 23. This instruction is provided for converting little-endian values to big-endian format and vice ...

Now I might have misunderstood what you wanted (I am not a C programmer) but is this what you are looking for?

Re: Array index out of bounds (array in a structure)

The explaination doesn't make sense.
If it works with a constant then why not a variable as both are defined (and set) before the structure/array is defined.
And why would the ReDim work with a variable and not a Dim?

Also, I found the the issue with my hang and it was not related to this issue ...

Re: Folder archiver (pretty quick)

I actually use a program from IBM called CDP.
The main two features are that it backs up files when they are closed (so when you close a source file, it gets backed up immediately) and does this to two places.
For example, on my laptop, I back up to the local drive (20 versions and use no more than ...

If you haven't already solved this, the following mught be of some help.

The second parameter is the IP address of the MySQL server you are trying to connect to.
