struggling with VISTA 64-bit

[Greg Lyon]

Which true compiler you know (except VISUAL STUDIO) that offers already such feature?

C Compilers
  Pelle's C
  GCC

Assemblers
  PoAsm (comes with Pelle's C)
  GoAsm

Who has ever done pointer marshalling with Pb9?

I have no idea how to do this myself.

[Petr Schreiber]

Hi Patrice,

maybe wrong idea, but what about using QUADS (64bit opposing to 32bit DWORD) to store pointer?
I guess this alone would not be sufficient, but could be part of the right path?

Maybe using something like:

Code Select Expand


%TARGET_BITS = 32

#IF %TARGET_BITS = 32
  MACRO wHANDLE = DWORD
  MACRO NAKEDPOINTER = DWORD
#ELSE
  MACRO wHANDLE = QUAD
  MACRO NAKEDPOINTER = QUAD
#ENDIF


... could be good practise? Don't know...

Petr,

Unfortunatly this couldn't be as simple as this.

I have checked several 64-bit application(s) with 32-bit DLL(s) and i always get an error message telling me that this couldn't be done.

The macros are useful when you have to compile the same source with a 32 bit or 64 bit compiler, but a 32 bit application can't use 64 bits DLLs and 64 bit applications can't use 32 bit DLLs.

32 bit applications can use 64 bit COM out of process servers and 64 bit applications can use 32 bit out of process servers, but with in-process servers you will have the same problem that with standard DLLs.

Yes "le serpent se mord la queue" (snake is biting his tail), i wouldn't have to wait too long before PB-64 is coming out, or i'll have no other choice than moving all my code to C, fortunatly i wrote it in pure SDK.

For those, like me, who do not know exaclty what a "thunking mechanism" means,
here is the begining of an answer:

I did further test on VISTA 64-bit, and i encountered a strange problem with the old GDI StretchBlt API that sometimes failed without any error with 32-bit bitmap (looks like an Alpha channel problem), while using the Alphablend API (in the same situation) always works fine.

@Patrice,
I guess you are on the wrong road.

In Vista 64 or not, applications can only sent messages to Applications when they have the same rights.

Just start your application "as Admin" and see what happens.
I the same way you may have trouble to read colour-values from windows, which are from higher-righted processes.

This is part of the new UAC-Safety-System

Well, i think I am (already) aware of this 

Added:
I have used the VISTA 32-bit since almost two years in administrator mode, and with the UAC being turned off.

Read the whole thread about the issues between 32-bit and 64-bit. Search also on Google for mixing X64 with 32-bit applications.

[Theo Gottwald]

ok, was just a guess. I think i should try next time first :-).

[Patrice Terrier]

Other VISTA 64 issue(s), i have encountered:

1 - I am unable to remove the small arrow overlay from the desktop shorcuts.
2 - I am unable to print (with my wi-fi HP Photosmart C 6180) from IE7, while it does just fine with FireFox.

Note: I didn't had these problems with VISTA 32-bit

Do we need a 64 bit compiler?

[Patrice Terrier]

Theo,

YES, we need a 64-bit compiler to work with those Windows OS runing in X64 mode(XP, 2005, VISTA and now Windows 7).

Added:
So far, i do not need "bells and whistles", if this could help to produce it faster

[Patrice Terrier]

I just downloaded and installed the C# VS2008 Express Edition, to try it with my PowerBASIC GDImage.dll.

Unfortunatly it doesn't work with it, because i am on VISTA x64 and the VS2008 generates x64 code instead of x32, and so far i didn't find how to configure the Express Edition to generate a 32x target solution.

If you know how to setup the VS2008 Express Edition to target the x32 platform, i would be glad to learn about it.
