Code: Select all

Have fun with it. Improve on it, Steal from it. Do as you wish.
I know its not much but wanted to give back something for all the help I have received:
; I named the executable "PBfingerprinter" But call it what you want.

[EDIT] 08/28/24 -- NEW and improved with big THANKS to HeXOR for the tip that led to the addition of these two lines enabling "SendTo" context menu selection to fingerprint files:

fingername$ = ProgramParameter()
fingerUpdate = #True

[TIP] do Winkey + R and type shell:sendto
Press enter and add a shortcut pointing to your PBfingerprinter program.
Now you can right ckick any file, select [Send To] > [PBfingerprinter]
and get the fingerrprint value for your send to file
Very handy if you download a lot of ISO files.

[EDIT] 08/29/24 -- I cleaned up the "Be Prepared To Wait" comment.
[EDIT] 09/12/24 -- "Be prepared to wait" comment augmented by Values determined in the Select CPU section. Maybe someone can suggest better means of adjustment.

[EDIT] 09/17/24 app was opening showing immediate error, so I changed this line:

Code: Select all

  fingerUpdate = #True

TO THIS:

Code: Select all

  If fingername$
    fingerUpdate = #True
  EndIf

[Randy Walker]

The one thing it is really missing is ability to use in the "sendto" context menu. I know I would have to put a shortcut in the sendto folder but I assume the compiled app would need to be able to accept parameters. I've tested using a shortcut in the sendto folder but does not work from the "sendto" context menu.

[SOLVED] 08/28/24 -- Thanks to HeXOR for his tip about programparameter() I was able to get SendTo working as hoped.

[normeus]

I set this one for one file to keep it simple, but you can do multiple files and also you might not want to display the GUI if the program is run by sending files to it. to test without creating an EXE go to Compiler->Compiler Options->Compile/run (tab) and add a filename to "Executable Commandline:"

Code: Select all

 If CountProgramParameters()=1  ; if there is one file exactly get the info
   File$ = ProgramParameter()
   path$ = GetPathPart(File$)
   filename$ = GetFilePart(File$)
   comandline=1
EndIf
If File$<>""
   ;load the info into the rest of the program
   
EndIf
If OpenWindow(0, 200, 200, 395, 260, "PureBasic Window", #PB_Window_SystemMenu | #PB_Window_MinimizeGadget | #PB_Window_MaximizeGadget)
   
   
     TextGadget(0,10,10,75,200,"Full Filename")
     StringGadget(1, 85, 10, 225, 25, File$)
     StringGadget(2, 85, 40, 225, 25, path$)
     StringGadget(3, 85, 70, 225, 25, filename$)

  Repeat
    Event = WaitWindowEvent()

    If Event = #PB_Event_CloseWindow  ; If the user has pressed on the close button
      Quit = 1
    EndIf

  Until Quit = 1
  
EndIf

End   ; All the opened windows are closed automatically by PureBasic

go to Compiler->Compiler Options->Compile/run (tab) and add a filename to "Executable Commandline:"

I didn't know it could be used like that. There were times when I needed this. Testing any tools for PureBasic requires this command line

Protection from wrong choice

Code: Select all

Global StandardFile$
StandardFile$ = GetPathPart(ProgramFilename())    ; set initial file+path to display
; StandardFile$ = GetTemporaryDirectory()    ; set initial file+path to display
; StandardFile$ = GetFilePart(ProgramFilename())    ; set initial file+path to display
; StandardFile$ ="file.iso"    ; set initial file+path to display
; StandardFile$ = ProgramFilename()    ; set initial file+path to display
; StandardFile$ = ""    ; set initial file+path to display

Procedure.s FileSelection()
	ProcedureReturn OpenFileRequester("Please choose file for test", StandardFile$, "All files (*.*)|*.*", 0)
EndProcedure

fingername$ = ProgramParameter()
If Not Asc(fingername$) Or FileSize(fingername$) < 0
	fingerName$ = FileSelection()
	If Not Asc(fingername$) Or FileSize(fingername$) < 0
		End
	EndIf
EndIf

You can write a program something like this. That is, compare two files or an existing hash.

Happy to report that your SHA2 matches an Ubuntu server download, Randy

That's actually why I created the app to begin with. Downloading CentOS ISOs on a regular basis.

[Randy Walker]

The only remaining thing that bothers me about PBfingerprinter is this simple line:

Code: Select all

If FileSize(fingerName$) > 200000000

It should be regulated by processor speed as well as file size. And maybe also whether the file is onboard SSD or external USB drive, etc, but have no idea how to sample that info from inside PB.

Oh, but that is funny!

Instead of SendTo, you can add an item to the Explorer menu through the registry. Here is a program to add a menu item. I also have a program that adds itself to the registry, or removes it if necessary. Look for the line IsUserAnAdmin_, this is the import code.

Can't do it. I never touch my registry unless highly needed AND no other option.

[EDIT] -- -9/16/24 -- changed behavior on Esc key. Formerly would only hide the app window and leave it running in the background, totally undesirable behavior as a standalone. Original code was designed to operate in my main project so hiding the window was appropriate. Now as a standalone in the updated code above, Esc key will close the app.
