CPUINFO.EXE
Download (20k) free DLL and VB source here!
This sample
project demos how to obtain CPU information from Intel CPUs by
using the CPUInf package available on the Intel Website. I have
translated the original C declarations into a reusable VB module
called CPUInf32.bas. If you want to examine the original C header
files or source code you should download the
Intel CPUInf
developer package here.
[VERSION HISTORY]
1/25/99
Now suports Pentium II Celeron A CPUs! - Added one line to a
SelectCase statement. This shows how easy it is to add support
for future processors too!
9/25/98
Because of feedback from a couple of intrepid VB'ers, I
discovered that the original CPUINFO.EXE had two functions which
were not reliable in all cases. I had originally tried to work
around the incompatibilities in the Intel CPUinf32.dll as an
exercise, but because of the problems I have decided to modify
and recompile the C DLL to be more "VB-friendly".
Because of this, and in order to avoid version problems with the
Intel DLL, I have renamed the C DLL to vbCPUInf.dll. This new
package should be faster and more reliable under VB and features
the following expanded CPU benchmarking functions:
cpunormspeed()
cpurawspeed()
vbcpuspeed()
Techniques demonstrated in this
project
--------------------------------------- |
-Calling
functions in a 3rd party DLL function library
-Working with register-level "packed bitfields"
-Handling a 64bit integer by using a currency type to
receive thevalue and then using RTLMoveMemory() to
transfer it to 2 long types |
Useful functions in CPUInf32.bas
-------------------------------- |
