Using System.Gadget.Settings

Using System.Gadget.Settings

  Always use readString for strings, otherwise it may return a number instead of a string which may cause type conflicts.
  
  eg. Using read will return the following incorrect types:
  "123" will return the number 123, not the string "123"
  "true" will return the boolean value true, not the string "true"
  
  
  Advantanges of Javascript over VB. Well, you have access to all the HTML trigged values like "event.screenX" for a start. Not to mention having access to the whole HTML structure through getElementByID etc.
  
  In short, Javascript is more suited to web development than VB. You'll still need VB here and there, such as presenting dialogues to users, because MS think they're bad for the user experience (shame they don't apply the same rule to their own software! )

  Some parts of the 'System' APIs that the sidebar exposes will not work correctly from VBScript. These failures, in some cases, are quite difficult to debug. If you absolutely must use VBScript, then I recommend using javascript for most of your code, VBScript for the minimal parts necessary, and don't use the 'System' APIs from VBScript code.

  I see the value in settings.ini

  System.Gadget.Settings.Write "Record", dtmSystemUptimeSecs

  time = System.Gadget.Settings.Read(Record)

  Record.innerText = "Record: " & time

  If I put this then the "Record: " text dissapears, if I comment out the time = line & the time variable then I see the text.

  Do I have to load the settings somehow I don't have a settings.html, I just though you could save values

  How big is large for write string

  Try ReadString:
  
  System.Gadget.Settings.Write "Record", "100"
  sTime = System.Gadget.Settings.ReadString("Record")
  Record.innerText = "Record: " & sTime
  
  If it still doesn't work, you've probably come across the disappearing System.* bug (bug#11 on the known bugs list).
  
  Also try rewriting it as Javascript with an error trap:
  
  try{
  

  System.Gadget.Settings.Write("Record", dtmSystemUptimeSecs);
  sTime = System.Gadget.Settings.ReadString("Record");
  Record.innerText = "Record: " + sTime;
  

  } catch(err) {Record.innerText = err}

  Post the whole code, so I can have a look. This is painful!

  That doesn't seem to work I must be missing something
  

• JIM.H.

  It looks okay to me, does the value get written to the settings.ini file
  
  If it's large, you may well need to use readString/writeString

  OK, the readstring thing didn't work.

  with the JS I get [object Error]

  method names in the gadget API are lower case ('read' and 'write'). If possible, I recommend using javascript instead of vbscript in your gadget code.

  What the advantage of Java over VB

  When should I use readString over read

  Seems fixed now as well

  It's really strange what's going on thanks for your help!!

  Sub Times

  On Error Resume Next

  Set objLocator = CreateObject("WbemScripting.SWbemLocator")

  Set objWMIService = objLocator.ConnectServer(MachineName, "root\cimv2")

  Set colOperatingSystems = objWMIService.ExecQuery("Select * from Win32_OperatingSystem")

  For Each objOS in colOperatingSystems

  dtmBootup = objOS.LastBootUpTime

  dtmLastBootupTime = WMIDateStringToDate(dtmBootup)

  dtmSystemUptimeSecs = DateDiff("s", dtmLastBootUpTime, Now)

  Uptime.innerText = "Uptime: " & SecondsToDateString(dtmSystemUptimeSecs)

  Next

  System.Gadget.Settings.Write "Record", dtmSystemUptimeSecs

  RecordTime = System.Gadget.Settings.Read("Record")

  Record.innerText = "Record: " & RecordTime

  setTimeout "Times()", 30000

  End Sub

  That serves me right for copying the original code! Thanks for pointing that one out Bruce.
  
  So you're code needs to be changed to:
  
  System.Gadget.Settings.write "Record", dtmSystemUptimeSecs
  RecordTime = System.Gadget.Settings.read("Record")

  You've got a typo and a type conflict:
  
  System.Gadget.Settings.Write "Record", dtmSystemUptimeSecs
  time = System.Gadget.Settings.Read("Record")
  Record.innerText = "Record: " & CStr(time)
