Hey Gary,

You should be able to get at least 2gb,
even more depending on the partition type and OS,
a compiler could impose some limit.

This one use a 778,371,072 bytes file with no problem.
Could you describe how you did it?

Code:

' MyBigRes.rc...
' #include "resource.h"
' 123 RCDATA  "Some742gbFile.iso" //778,371,072 bytes file

#COMPILE EXE '#CC 5.07#
#DIM ALL
#INCLUDE "Win32Api.inc"
#RESOURCE "MyBigRes.pbr"
'_____________________________________________________________________________

FUNCTION PBMAIN() AS LONG
 LOCAL hInst           AS DWORD
 LOCAL hRes            AS DWORD
 LOCAL hData           AS DWORD
 LOCAL pData           AS DWORD
 LOCAL sData           AS STRING

 hInst = GetModuleHandle("")
 hRes  = FindResource(hInst, "#123", BYVAL %RT_RCDATA)
 IF hRes THEN
   hData    = LoadResource(hInst, hRes)
   IF hData THEN
     pData = LockResource(hData)
     IF pData THEN
       STDOUT FORMAT$(SizeofResource(hInst, hRes), "0,")
     END IF
   END IF
 END IF

 PRINT : PRINT "Type or click..." : MOUSE ON : MOUSE 3, UP : WAITKEY$

END FUNCTION

[QUOTE=Pierre Bellisle;n771044]Hey Gary,

a compiler could impose some limit.

This one use a 778,371,072 bytes file with no problem.

Your code apparently uses an external resource compiler to geberate your .pbr file.

I suspect Gary is using
#RESOURCE RCDATA ........

I just built a 1,000,000 byte executable using #BLOAT ( just displays a Msgbox)

Then complied another file with

#RESOURCE RCDATA BigExe "BigExe.exe"

It worked fine.

Edit: Oops, that was only 1,000,000 bytes. Let me try again!

**Stuart McLachlan** · 22 Mar 2018, 06:51 PM

Tried twice with a 1GB file and gave up after PB sat using 25% CPU resources for over half an hour each time.

No error though.

**Michael Mattias** · 22 Mar 2018, 07:33 PM

was trying to put a 785MB file into an EXE as a resource,

Why? Do you really need to do that? (I don't know but I just want to be sure you have thought about it).

Ok, maybe helpful...

1. Split the resource into, say, three or more chunks and assemble at runtime.

2. Make the resource either a RES or PBR file; do NOT use the inline resource definition statement, instead you will compile in the *.RES or *.PBR file. Note this is the way Pierre got this to work in Post #2 (Note also: Under PB now all resources have to be in the same format (RES or PBR), but we all know how to do that anyway).

3. Use a third-party tool to compile a *.RES and then use a third-party linker to link that *.RES into your EXE.

Hi Pierre,

I did this, where bigfile.zip is 785MB ...

Code:

#Resource RcData, 1000, "bigfile.zip"

And, Stuart,
Yes, I finally got the compiler to start cranking ... but it chugged along for quite a while before stopping/crashing with no error message.

And, MCM,
I've no problem going to another approach, but would like to know why #Resource approach doesn't work and perhaps know what the actual limitation is.

**Pierre Bellisle** · 22 Mar 2018, 09:25 PM

Gary,

You are using Windows 10, try to compile under Windows 7 if possible, if it works then it is a PowerBASIC / Windows 10 issue.

I'm sure that if you use an external .rc file under any OS, it will work all-wight and the ~2gb limit will prevail .

My test which I abandoned after 1/2 an hour or so, was under Win 7.

**Bob Carver** · 23 Mar 2018, 01:20 AM

I tested it with a 1.5GB iso file. PBWin 10.03 reads the entire file into memory in ~2MB chunks, and then exits with

Error 478 in c:\Test\PB\test.bas(4:001): Resource file error
Line 4: #RESOURCE RcData, 123, "H:\os\6001.18000.080118-1840_x86fre_Server_en-
us-KRMSFRE_EN_DVD.iso"

It didn't take half an hour for me though, took 90 seconds. A 550MB file actually produced an exe, but required 1.2GB of memory, in 42 seconds.

Since it reads the specified file completely into memory, PBWin would seem to need to be able to allocate 2x the size of the file + have space for all the Windows dlls and whatever else in the 2GB of address space as (my version at least) isn't LargeAddressAware.

I'm obviously guessing, but there's probably no hard maximum file size where the compiler outright rejects your rcdata files, but implementation wise, it seems to roughly be around 900MB-ish depending on how much code is generated, what other resources there are, etc.

**Gary Beene** · 23 Mar 2018, 08:11 AM

Hmm.... it's been a while since I created a PBR file. So, I loaded this one-line .RC file and compiled it (BigFile.zip is 785MB) ...

Code:

123  RCDATA  "BigFile.zip"

and, with the compiler set to "Create a .PBR file when compiling a .RC files", the compiler created a 785MB RES file, but a PBR file of only 100 bytes. I don't think that's how it's supposed to work!

From Help ...

When the "Create a .PBR when compiling .RC files" option on the compiler options tab is selected the IDE will also produce a .PBR file from the .RES file. This is achieved in one simple step: simply load the .RC file into the IDE and select Compile.

**Gary Beene** · 23 Mar 2018, 08:23 AM

But, Help does say that #Resource supports this syntax ...

Code:

#RESOURCE RES, "filespec.RES"

But when I use that syntax with the 785MB RES file that resulted from my compilation as mentioned above, the result is a 77KB EXE file.

**Rodney Hicks** · 23 Mar 2018, 10:08 AM

Gary, could you post all the code from the offending program before any functions or procedures?

**Dave Biggs** · 23 Mar 2018, 11:58 AM

Hi Rod,
This is some test code I used. Runs OK in Windows 7 but I get the same failed .exe when compiled in WIndows 10 as Gary sees..!
(Though my failed .exe is only 13K)

Code:

#Compile Exe
#Dim All
#Include "win32api.inc"
#Resource Res, "RCDataZip.res"

Function MakeFileFromRes(sPath As String, ResId As String) As Long
 Local datasize, filehandle As Long
 Local buffer As String

    buffer   = Resource$(RcData, ResID)
    datasize = Len(buffer)
    ? ResID,,"ResID"+Str$(datasize)

   If datasize > 0 Then
     winbeep 800, 200
      filehandle = FreeFile
      Open spath For  Binary  As filehandle
        Put$ filehandle, buffer
      Close filehandle
      Function = %TRUE
   Else
      Function = %false
   End If
End Function
'------------------/MakeFileFromRes

Function PBMain () As Long
 Local lRes As Long

  lRes = MakeFileFromRes("RCDataExtracted.zip", "RESID")
  ? "Done",,Str$(lRes)

End Function
'------------------/PBMain

#If 0
//rc file contents - saved As RCDataZip.rc

ResId RcData "ResData.zip"     // 835+MB archive. Compiled To .\RCDataZip.res
#EndIf

**Pierre Bellisle** · 23 Mar 2018, 12:18 PM

Hey Gary,
What if you try manually?

REM Create a .res
X:\Basic\PB-Compiler\bin\rc.exe "X:\Basic\Bas\SRC\MyFile.rc"

REM Create a .pbr
X:\Basic\PB-Compiler\bin\pbRes.exe "X:\Basic\Bas\SRC\MyFile.res"

REM In the bas file have
#RESOURCE "MyFile.pbr"

REM Create a .exe
X:\Basic\PB-Compiler\bin\pbWin.exe "X:\Basic\Bas\SRC\MyFile.bas" /L /I"X:\Basic\PB-Compiler\\WinApi"

**Rodney Hicks** · 23 Mar 2018, 04:53 PM

Dave, I don't have a Win 10 system but I couldn't get your code to run on Win 7 with my 435,000+kb file. I did change #RESOURCE RES to #RESOURCE RCDATA, 1000, filename and changed "lRes = MakeFileFromRes("RCDataExtracted.zip", "RESID")" to "lRes = MakeFileFromRes("RCDataExtracted.zip", "#1000")" and it ran like a charm with the #IF block commented out. I get the Error 478 resource file error with your code on my machine.

**Pierre Bellisle** · 23 Mar 2018, 06:49 PM

Using the method above, I did a manual compile under Windows 10.
pbRes failed to create a valid .pbr from a valid 760mb .res file. The result was a 100 bytes file.
Same procedure worked fine under Windows 7 though. [Added: Windows 8.1 worked fine also.]

**Dave Biggs** · 23 Mar 2018, 09:28 PM

Hi Rod,
You need to create a .RC file using the line inside the #IF block. Then compile it with RC.EXE to generate the .RES file.

(Otherwise..)

Error 478 in C:\PBWin10\Samples\RCData\RCDataExe.bas(4:001): Resource file error
Line 4: #Resource Res, "RCDataZip.res"

**Rodney Hicks** · 23 Mar 2018, 10:31 PM

Right, Dave. I've been spoiled, never gave thought to the multi step process.All is good here.

**Dave Biggs** · 23 Mar 2018, 10:53 PM

Did some more testing - using the #Resource RCDATA, RESID, "ResData.zip" method - no pre compiling to RES / external resource file.
In Windows 10 things go awry on my PC when the .zip file exceeds 660MB or so.

Above the limit, a small .exe file (~13k) is written to disk but PBWin.exe sits in memory eating up 25% of my CPU until killed with Task Manager's 'End Task'.

Code:

#Compile Exe
#Dim All
#Include "win32api.inc"
'#Resource Res, "RCDataZip.res"
#RESOURCE RCDATA, RESID, "ResData.zip"

Function MakeFileFromRes(sPath As String, ResId As String) As Long
 Local datasize, filehandle As Long
 Local buffer As String

    buffer   = Resource$(RcData, ResID)
    datasize = Len(buffer)
    ? ResID,,"ResID"+Str$(datasize)

   If datasize > 0 Then
     winbeep 800, 200
      filehandle = FreeFile
      Open spath For  Binary  As filehandle
        Put$ filehandle, buffer
      Close filehandle
      Function = %TRUE
   Else
      Function = %false
   End If
End Function
'------------------/MakeFileFromRes

Function PBMain () As Long
 Local lRes As Long

  lRes = MakeFileFromRes("RCDataExtracted.zip", "RESID")
  ? "Done",,Str$(lRes)

End Function
'------------------/PBMain

That's what I found on Win 7 too.
