A function for obtaining the purebasic path (Windows & Linux)

Thank for Freak & Gnozal

Hi,

Nice example and thanks for sharing.

Also, the purebasic path should be given in environment variables if pb is correctly installed on linux.

Code: Select all

Procedure.s PB_GetPBFolder()
  CompilerSelect #PB_Compiler_OS
    CompilerCase #PB_OS_Windows
    ;{
      Protected hKey1.l, Type.l, Res.l, Folder.s, lpbData.l, cbData.l, WindowsVersion.l
      cbData = (#MAX_PATH * 2) + 2
      lpbData = AllocateMemory(cbData)
      Folder=""
      hKey1=0
      Type=0
      Res=-1
      Select OSVersion()
        Case #PB_OS_Windows_95, #PB_OS_Windows_98, #PB_OS_Windows_ME;{
          Debug "Detected OS : Windows 95/98/ME"
          Res=RegOpenKeyEx_(#HKEY_LOCAL_MACHINE, "Software\Classes\PureBasic.exe\shell\open\command", 0, #KEY_ALL_ACCESS, @hKey1)
        ;}
        Case #PB_OS_Windows_NT3_51, #PB_OS_Windows_NT_4, #PB_OS_Windows_2000, #PB_OS_Windows_XP, #PB_OS_Windows_Server_2003;{
          Debug "Detected OS : Windows NT/2000/XP"
          Res=RegOpenKeyEx_(#HKEY_CLASSES_ROOT, "Applications\PureBasic.exe\shell\open\command", 0, #KEY_ALL_ACCESS, @hKey1)
        ;}
        Default;{ Win Vista / Server 2008
          Debug "Detected OS : Windows Vista/Server 2008"
          Res=RegOpenKeyEx_(#HKEY_CURRENT_USER, "Software\Classes\PureBasic.exe\shell\open\command", 0, #KEY_ALL_ACCESS , @hKey1)
        ;}
      EndSelect
      If Res = #ERROR_SUCCESS And hKey1
        If RegQueryValueEx_(hKey1, "", 0, @Type, lpbData, @cbData)=#ERROR_SUCCESS
          Folder = PeekS(lpbData)
          Folder = GetPathPart(StringField(Folder,2,Chr(34)))
        EndIf
        RegCloseKey_(hKey1)
      EndIf
      If lpbData
        FreeMemory(lpbData)
        lpbData=0
      EndIf
      ProcedureReturn Folder
    ;}
    CompilerCase #PB_OS_Linux
    ;{
    ProcedureReturn GetEnvironmentVariable ( "PUREBASIC_HOME" )
    ;}
  CompilerEndSelect
EndProcedure

Debug  PB_GetPBFolder()

Best regards

I improved the first code thanks to Hroudtwolf.

I don't understand the difference with

Code: Select all

Debug #PB_Compiler_Home

:roll:

#PB_Compiler_Home will give the path on your system, but in an another computer, the constant will be the same but may be not the folder of Purebasic.

This does not work with a fresh install of 4.20+. #HKEY_CLASSES_ROOT has been retired due to compatibility issues from insufficient privileges across user accounts. Only use _CLASSES on anything Windows 9x.
