PB_TOOL_Word and environment variables

[epidemicz]

Ok guys I found some cool code that sparked my interest the other day browsing the forums. You can see exactly it's purpose here: http://www.purebasic.fr/english/viewtop ... =MSDN+HELP.

The code:

Code: Select all

Define.s Word
Word = GetEnvironmentVariable("PB_TOOL_Word")
If Word
  If Right(Word, 1) = "_"
    Word = Left(Word, Len(Word) -1)
  ElseIf Left(Word, 1) = "#"
    Word = Right(Word,Len(Word) -1)
  EndIf
  RunProgram("rundll32.exe","url.dll,FileProtocolHandler http://www.google.de/search?q=site:msdn.microsoft.com+msdn+win32+" + Word + "&btnI=true", "")
EndIf

Now, for demonstration purposes, lets use some more code I found.

This code will display all of the environment variables:

If OpenWindow(0, 0, 0, 640, 520, "Environment Variables", #PB_Window_SystemMenu | #PB_Window_MinimizeGadget | #PB_Window_ScreenCentered)
   If CreateGadgetList(WindowID(0))
      ListIconGadget(0,10,10,621,500,"Variable",200,#PB_ListIcon_GridLines | #PB_ListIcon_FullRowSelect)
   EndIf
   
   AddGadgetColumn(0,1,"Data",400)
   If ExamineEnvironmentVariables()
      While NextEnvironmentVariable()
         AddGadgetItem(0,-1,EnvironmentVariableName()+Chr(10)+EnvironmentVariableValue())
      Wend
   EndIf

  Repeat
    EventID = WaitWindowEvent()

    If EventID = #PB_Event_CloseWindow
      Quit = 1
    EndIf

  Until Quit = 1
  
EndIf

My question:
Why doesn't PB_Tool_Word show up in the list of environment variables? Why aren't any of the other variables in the help file showing up? If these aren't available with ExamineEnvironmentVariables(), then how would we find them? For instance if there was another program we wanted to see their variables, would that be possbile, or do we just have to be told what they are?

PB_TOOL_IDE - Full path and filename of the IDE
PB_TOOL_Compiler - Full path and filename of the Compiler
PB_TOOL_Language - Language currently used in the IDE
PB_TOOL_FileList - A list of all open files in the IDE, separated by Chr(10)

PB_TOOL_Debugger - These variables provide the settings from the Compiler Options
PB_TOOL_InlineASM window for the current source. They are set to "1" if the option
PB_TOOL_Unicode is enabled, and "0" if not.
PB_TOOL_Thread
PB_TOOL_XPSkin
PB_TOOL_OnError

PB_TOOL_SubSystem - content of the "Subsystem" field in the compiler options
PB_TOOL_Executable - same as the %COMPILEFILE token for the commandline
PB_TOOL_Cursor - same as the %CURSOR token for the commandline
PB_TOOL_Selection - same as the %SELECTION token for the commandline
PB_TOOL_Word - same as the %WORD token for the commandline

PB_TOOL_MainWindow - OS handle to the main IDE window

This environment variables a set by the IDE, so only available for processes started by the IDE.
Your program start from explorer!

Wow, I gotcha now. Thanks ts-soft, and thanks for the msdn help tool I use it all the time, saves lots of typing
