added callback support to RAR_Unpack()

Works great here, thanks for sharing

added callback-support to RAR_Unpack(), see first posting.

Small Example:

Code: Select all

XIncludeFile "unRAR_Include.pbi"

Procedure RAR_Callback(msg, UserData, P1, P2)

  Select msg
    Case #UCM_NEEDPASSWORD
      Debug "Password needed"
      Debug "--------------"
      ProcedureReturn -1
  EndSelect
  Debug P1
  Debug P2
  Debug "--------------"
EndProcedure

Define File.s = OpenFileRequester("", "", "RAR-Archiv (*.rar)|*.rar", 0)
Define Path.s = PathRequester("Select Destinationpath", "")

If File
  RAR_Unpack(File, Path, "", @RAR_Callback())
EndIf

Thanks THOMAS

But i have a little problem
#UCM_NEEDPASSWORD

Posted: **Sun Jan 29, 2012 9:18 pm**

This constant is defined in the updated source in the first post.
For using read the documentation included in the download of unrar.dll!

Greetings - Thomas

// edit
better example:

Code: Select all

XIncludeFile "unRAR_Include.pbi"

Procedure RAR_Callback(msg, UserData, P1, P2)

  Select msg
    Case #UCM_NEEDPASSWORD
      Protected PWD.s = InputRequester("", "Password needed", "")
      If PWD
        PokeS(P1, PWD, -1, #PB_Ascii)
      Else
        ProcedureReturn -1
      EndIf
    
    Case #UCM_CHANGEVOLUME
      Select P2
        Case #RAR_VOL_ASK
          MessageRequester("", PeekS(P1, -1, #PB_Ascii) + #LF$ + "is missing", #MB_ICONERROR)
          ProcedureReturn -1
        Case #RAR_VOL_NOTIFY
          ProcedureReturn 0
      EndSelect
    Case #UCM_PROCESSDATA
      ; Process unpacked data
      ; for more information read the documentation "RARCallback.htm"
  EndSelect

EndProcedure

Define File.s = OpenFileRequester("", "", "RAR-Archiv (*.rar)|*.rar", 0)
Define Path.s = PathRequester("Select Destinationpath", "")

If File
  RAR_Unpack(File, Path, "", @RAR_Callback())
EndIf

Works like a charm, thanks again for all your greats works

Posted: **Sun Apr 29, 2012 5:44 pm**

ts-soft !! this is just great !

but (I always have some but, I'm sorry

), I have a problem with the use

here it is :

I'm developing a software (free of charge) to view image which are contained in *.zip or in *.cbr or *.cbz
These last two are in reality *.rar

Actually with the help of your MiniZip include I managed to add the zip support in my software (many many thanks for that ^^. And now I think of it, I will immediately add the credit of zip support ! (I forgot -_- ))

So now I've focus on the rar support. But the problem is : with the Zip lib, reading one file in the zip, extracting it in the memory, and using it with CatchImage() for exemple, was possible.
For now, with the unrar code, it's not possible

Or maybe I didn't understand something in the help ?

Do you think it's possible to use these lib with a function like that :
*memory_pointer = RAR_CatchFile(file.s, file_name.s)

I don't know, the documentation is not the best and my english is bad.

Posted: **Sun Apr 29, 2012 10:27 pm**

well ^^

I've done a little self ass-kicking, and here is my little contribution :

Code: Select all

Procedure __Callback_RAR(msg, UserData, P1, P2)
	
	Select msg
    Case #UCM_NEEDPASSWORD
      Protected PWD.s = InputRequester("", "Password needed", "")
      If PWD
        PokeS(P1, PWD, -1, #PB_Ascii)
      Else
        ProcedureReturn -1
      EndIf
   
    Case #UCM_CHANGEVOLUME
      Select P2
        Case #RAR_VOL_ASK
          MessageRequester("", PeekS(P1, -1, #PB_Ascii) + #LF$ + "is missing", #MB_ICONERROR)
          ProcedureReturn -1
        Case #RAR_VOL_NOTIFY
          ProcedureReturn 0
      EndSelect
      
    Case #UCM_PROCESSDATA
      ; Process unpacked data
      ; for more information read the documentation "RARCallback.htm"
      
      CopyMemory(P1, PeekI(UserData), P2)
      PokeI(UserData, PeekI(UserData) + P2)
      
      
  EndSelect

EndProcedure

Procedure.i RAR_CatchFile(rarfile.s, FileNumber.l, password.s = "")
	Protected hRAR, *mem.i, *mem_1.i, res, a
	Protected rarheader.RARHeaderDataEx
	Protected raropen.RAROpenArchiveDataEx
	
	CompilerIf #PB_Compiler_Unicode
		raropen\ArcNameW = @rarfile
	CompilerElse
		raropen\ArcName = @rarfile
	CompilerEndIf
	
	raropen\OpenMode = #RAR_OM_EXTRACT
	raropen\Callback = @__Callback_RAR()
	raropen\UserData = @*mem_1
	
	
	hRAR = RAROpenArchiveEx(@raropen)
	
	If hRAR = 0 : ProcedureReturn 0 : EndIf
	
	RARSetPassword(hRAR, password)
	
	For a = 1 To FileNumber - 1
		If RARReadHeaderEx(hRAR, @rarheader) = #ERAR_END_ARCHIVE : ProcedureReturn 0 : EndIf
		
		CompilerIf #PB_Compiler_Unicode
			RARProcessFileW(hRAR, #RAR_SKIP, #NULL$, #NULL$)
		CompilerElse
			RARProcessFile(hRAR, #RAR_SKIP, #NULL$, #NULL$)
		CompilerEndIf
	Next
	
	If RARReadHeaderEx(hRAR, @rarheader) : ProcedureReturn 0 : EndIf
	If rarheader\FileAttr & #FILE_ATTRIBUTE_DIRECTORY : ProcedureReturn 0 : EndIf ; on ne peux extraire en mémoire un répertoire
	
	*mem = AllocateMemory(rarheader\UnpSize)
	
	If *mem = 0 : ProcedureReturn 0 : EndIf
	
	*mem_1 = *mem
	
	CompilerIf #PB_Compiler_Unicode
		res = RARProcessFileW(hRAR, #RAR_TEST, #NULL$, #NULL$)
	CompilerElse
		res = RARProcessFile(hRAR, #RAR_TEST, #NULL$, #NULL$)
	CompilerEndIf
	
	If res
		FreeMemory(*mem)
		
		ProcedureReturn 0
	EndIf
	
	RARCloseArchive(hRAR)
	
	ProcedureReturn *mem
EndProcedure

Add the procedure to your code to work, I have made an exemple, but it need an include of my own to work nicely (it quickly display the image in a rar file, without unpacking them on the disk !)

Thanks to that I'm able to finish a long awaited feature in my project

Thanks again Ts !
