Resource

[Droopy]

Code updated For 5.20+

With this functions you can include files, and use it with purebasic functions like CatchImage / CatchSound or extract included file .

Create a file with RC extension and include it as RC_DATA Resource type
Path can be absolute or relative
Exemple :

REG RCData "C:\WINDOWS\REGEDIT.EXE"
SON RCData "son.wav"
IMAGE RCData "image.bmp"

Code: Select all

;/ SaveResourceAs(Name.s,File.s) Save the resource as a file
;/ GetResourcePointer(Name.s) is usefull with PureBasic CatchXXX functions (CatchImage / CatchSound ... )

ProcedureDLL SaveResourceAs(Name.s,File.s)
  
  ; (Use GetModuleHandle_ if you want to specify another file)
  
  HandleResource= FindResource_(0,@Name,#RT_RCDATA)
  If HandleResource
    HandleGlobalMemoryBlock=LoadResource_(0,HandleResource)
    PointerFirstByteOfTheResource=LockResource_(HandleGlobalMemoryBlock)
    
    ; Get size of the resource
    Size= SizeofResource_(Handle,HandleResource)
    
    ; Save the file
    FileId=OpenFile(#PB_Any,File)
    If FileId
      WriteData(FileId,HandleGlobalMemoryBlock,Size)
      CloseFile(FileId)
    EndIf
    
    ; Test if the file is written
    If FileSize(File)=Size
      ProcedureReturn 1
    EndIf
  EndIf
  
EndProcedure

ProcedureDLL GetResourcePointer(Name.s)
  
  ; (Use GetModuleHandle_ if you want to specify another file)
  
  HandleResource= FindResource_(0,@Name,#RT_RCDATA)
  If HandleResource
    HandleGlobalMemoryBlock=LoadResource_(0,HandleResource)
    PointerFirstByteOfTheResource=LockResource_(HandleGlobalMemoryBlock)
    
    ProcedureReturn HandleGlobalMemoryBlock
  EndIf
EndProcedure

ProcedureDLL GetResourceSize(Name.s)
  
  ; (Use GetModuleHandle_ if you want to specify another file)
  
  HandleResource= FindResource_(0,@Name,#RT_RCDATA)
  If HandleResource
    HandleGlobalMemoryBlock=LoadResource_(0,HandleResource)
    PointerFirstByteOfTheResource=LockResource_(HandleGlobalMemoryBlock)
    
    ; Return the size of the resource
    Size= SizeofResource_(Handle,HandleResource)
    ProcedureReturn Size
  EndIf
  
EndProcedure

I've already made good use of this.

Thanks for sharing Droopy.

For images, you can also use LoadBitmap() API.

Put this on your .RC file:

Code: Select all

MY_IMAGE IMAGE "myimage.bmp"

And then you can get the image handle in your PB source.

Code: Select all

H_instance=GetModuleHandle_(0)
IMG_Sfondo=LoadBitmap_(H_instance,"MY_IMAGE")

You can use IMG_Sfondo with usual gfx PB commands. Please notice that IMG_Sfondo is the handle, not the internal ID that PureBasic can assign (unless you use #PB_ANY). For example:

Code: Select all

IMG_Sfondo=CatchImage(#PB_ANY,?myimagelabel)

could you do a little more explanation on this? what to use and an example? i'd like to see more of this...

Thanks Seldon for the info

I've put together few "PB alike" functions.

Code: Select all

Procedure GetRCPointer(Name.s) 
 H_resource_ID=FindResource_(0,@Name,#RT_RCDATA) 
 If H_resource_ID
  H_global_memory_block=LoadResource_(0,H_resource_ID) 
  If H_global_memory_block
   H_resource_pointer=LockResource_(H_global_memory_block) 
   If H_resource_pointer
    ProcedureReturn(H_resource_pointer) 
   EndIf
  EndIf
 EndIf 
EndProcedure

Procedure GetRCSize(Name.s)
 H_resource_ID=FindResource_(0,@Name,#RT_RCDATA) 
 If H_resource_ID
  size=SizeofResource_(0,H_resource_ID) 
  ProcedureReturn(size)
 EndIf 
EndProcedure

Procedure CatchImageRC(ImageID,Name.s)
 resource_pointer=GetRCPointer(Name)
 If resource_pointer
  IMG_tmp=CatchImage(ImageID,resource_pointer) 
  ProcedureReturn(IMG_tmp)
 EndIf
EndProcedure

Procedure CatchSpriteRC(ImageID,Name.s,Mode)
; 'Mode' parameter can be '0'
 resource_pointer=GetRCPointer(Name)
 If resource_pointer
  IMG_tmp=CatchSprite(ImageID,resource_pointer,Mode) 
  ProcedureReturn(IMG_tmp)
 EndIf
EndProcedure

Procedure CatchSoundRC(SoundID,Name.s,Length)
; Specify 'Length' parameter if using OGG
 resource_pointer=GetRCPointer(Name)
 If resource_pointer
  SND_tmp=CatchSound(SoundID,resource_pointer,Length) 
  ProcedureReturn(SND_tmp)
 EndIf
EndProcedure

Droopy: You're welcome. Thank you! BTW, I think LoadBitmap() API does more or less what we do manually (i.e. it calls FindResource(), then LoadResource(), etc... ) , though it's handy for 2d images especially for icons or images inside gadgets (it can't be used for sprites as they need to pass from CatchSprite() ).
