Same result when run as limited or with admin rights.
Code: Select all
Debug FileSize("C:\Windows\System32\mblctr.exe") ; -1

That file doesn't exists in \SysWoW64. Try with the x64 PB Compiler, it should work okay then.
Using 32Bit App, to see 64bit system32, use instead
Debug FileSize("C:\Windows\
sysnative\mblctr.exe")

Issue confirmed here on Windows 7 x64 with PB 5.21 LTS x86.
The code works here correctly though with PB 5.21 LTS x64.

Not a bug really.

No Bug, only virtualisation
Code: Select all
Define.s File = "C:\Windows\System32\mblctr.exe"
CompilerIf #PB_Compiler_Processor = #PB_Processor_x86
File = "c:\Windows\Sysnative\mblctr.exe"
CompilerEndIf
Debug FileSize(File)

But that produces an exe for only one processor type. Do
I have to compile two versions of my app from now on?
And it's not a good enough solution, anyway, because that's
just ONE file. Does my app have to conditionally compile a
whole folder of Windows files to ensure they look right on
any given PC? It's a horrible way to "fix" the problem.
And when my users start saying "what's this SysNative all
about", I then have support issues where I have to explain
that what they see in the "Properties" box isn't true at all.
Ah, damn I hate Windows sometimes. Don't know why I'm
still coding for it. POS operating system.

If your 32-Bit program run on a 64-Bit OS, you have to use sysnative dir, it is the same with some registry keys.
The redirection is a windows feature
, not a PB Bug

As a possible solution, is it safe to just search/replace the
"System32" part of the string with "SysNative" if FileSize()
returns -1, then? Seems a lot simpler and the user won't
know it was done that way to present the correct size.
Like this:
Code: Select all
f$="C:\Windows\System32\mblctr.exe"
s=FileSize(f$)
If s=-1
s=FileSize(ReplaceString(f$,"\System32\","\SysNative\"))
EndIf
Debug s

Check if the sysnative dir exists, if exist, use it!
On a 32-Bit OS you wouldn't found this dir.

Not that simple. It doesn't "exist" on my 64-bit Windows.
Can't view it in Explorer or with the "dir" DOS command.
And yes, I'm viewing all files/folders/nothing hidden/etc.

It's a pseudo directory for 32App on 64bit OS, using Filesize and determining if the folder exists won't work. Use one of many ways already mentioned on the forums.

Use a 32-Bit FileManager (Total Commander recommend).
Windows-Explorer is bad for none DAUs

Filesize() is used heavily in some projects. Having said that, .. speed is important. This extra stage would be undesired.

I know! That's why it sucks to have to do the check.
But if you DON'T check, then you're going to have bugs,
just as I showed in my first post. You can't trust FileSize.

What's your case scenario for your project? Code be different based on your needs. Is it important for your 32App to see 64bit versions of files?
