how do i get the cpu speed?

thanx in advance

Just ComputerName to your computer name.

any other ways to do it?

IROY55, can you please explain what is "WinMgmts" and how it works? I never came accross something like that before..:confused:

For more detaied explanation visit MS sites:
http://msdn.microsoft.com/library/de..._processor.asp
http://msdn.microsoft.com/library/de...ng_a_class.asp

but how can you find the speed without using that piece of code. There are other ways or not???

I remember in the old days where I acquire a piece of
QBasic code(that's rite! MS-DOS stuffs), which, it has a DoLoop,
and in the loop it keeps on incrementing a variable(or perhaps
some sort of calculation, I forgot), and after about 5 seconds,
the results are divided by 5 seconds and voila u got the CPU
speed. It's quite accurate, though.

I've also made such thing, but in VB6 and with a nice meter.

This is really sounds silly: DOS is not multitsaking OS, so you may probably calculate somewhat CPU speed, on the other hand Windows is a multitasking OS (or at least pretends to be). Calculating your CPU speed using this method will give you different results depending on how much Resources/CPU/Memory usage, etc.

Jian,

can you describe what you are talking about...

I tried the loop and then divided it by 5 (for 5 seconds) and I get a return of 53195.4 . Now how does that translate to processor of 850 Meg?? ( my PC is a 850)

:confused:


Code:

Dim StartTime
Dim X As Long

X = 0
StartTime = Time
Do Until DateDiff("s", StartTime, Time) >= 5
X = X + 1
DoEvents
Loop
Debug.Print X / 5

Well, if you download the Microsoft SDK, then this answer might
work (though I haven't looked):

Outside of the suggestion listed above in this thread, I don't
think VB can natively retrieve the CPU speed. The way I've
always learned to do it is through a calculation in assembly
(which you could do inline in C/C++ I'm sure).

Pillejunior,

There are several posts on the forum dealing with this subject. I recently made a dll that will get any info I need of a computer.

The bottom line is, if you have a Win9x platform, you can not get the CPU speed unless you create a C++ dll and use some assembly code. I found a dll out there that will give you just the cpu speed. Here is the link

The WMI stuff seems to only work on the an NT platform and mainly 2000 and later.

You can get the speed by using the following code on a Win200/XP machine to retrieve the speed from the registry.

VB Code:

Private Const KEY_CREATE_LINK = &H20
Private Const KEY_CREATE_SUB_KEY = &H4
Private Const KEY_ENUMERATE_SUB_KEYS = &H8
Private Const KEY_EVENT = &H1     '  Event contains key event record
Private Const KEY_NOTIFY = &H10
Private Const KEY_QUERY_VALUE = &H1
Private Const KEY_SET_VALUE = &H2
Private Const READ_CONTROL = &H20000
Private Const SYNCHRONIZE = &H100000
Private Const STANDARD_RIGHTS_READ = (READ_CONTROL)
Private Const STANDARD_RIGHTS_ALL = &H1F0000
Private Const STANDARD_RIGHTS_WRITE = (READ_CONTROL)
Private Const KEY_WRITE = ((STANDARD_RIGHTS_WRITE Or KEY_SET_VALUE Or KEY_CREATE_SUB_KEY) And (Not SYNCHRONIZE))
Private Const KEY_ALL_ACCESS = ((STANDARD_RIGHTS_ALL Or KEY_QUERY_VALUE Or _
                              KEY_SET_VALUE Or KEY_CREATE_SUB_KEY Or _
                              KEY_ENUMERATE_SUB_KEYS Or KEY_NOTIFY Or _
                              KEY_CREATE_LINK) And (Not SYNCHRONIZE))
Private Const KEY_READ = ((STANDARD_RIGHTS_READ Or KEY_QUERY_VALUE Or KEY_ENUMERATE_SUB_KEYS Or KEY_NOTIFY) And (Not SYNCHRONIZE))
Private Const KEY_EXECUTE = ((KEY_READ) And (Not SYNCHRONIZE))
 
Private Const HKEY_LOCAL_MACHINE = &H80000002
 
Private Declare Function RegQueryValueEx Lib "advapi32.dll" Alias "RegQueryValueExA" _
  (ByVal hKey As Long, ByVal lpValueName As String, ByVal lpReserved As Long, _
  lpType As Long, lpData As Any, lpcbData As Long) As Long
Private Declare Function RegOpenKeyEx Lib "advapi32.dll" Alias "RegOpenKeyExA" _
  (ByVal hKey As Long, ByVal lpSubKey As String, ByVal ulOptions As Long, _
  ByVal samDesired As Long, phkResult As Long) As Long
Private Declare Function RegCloseKey Lib "advapi32.dll" (ByVal hKey As Long) As Long
 
Public Function ProcessorSpeed() As String
 
' If we are on a WinNT Platform, we can do this
 
    Dim lValue As Long
    Dim GroupHandle As Long
    Dim Section As String
    
    Section = "HARDWARE\DESCRIPTION\System\CentralProcessor\0"
    
    ' Open the Registry Key
    RegOpenKeyEx HKEY_LOCAL_MACHINE, Section, 0&, KEY_READ, GroupHandle
    
    ' Get the value
    RegQueryValueEx GroupHandle, "~Mhz", 0&, 0&, lValue, 4&
  
    ' Close the Registry
    RegCloseKey GroupHandle
    
    'Give it to me
    ProcessorSpeed = lValue & " Mhz"
  
 
End Function

I hope this helps you out.
