Hi,

i'm building application wich uses processor ID for license purposes. Now i'm rewriting some code from C# to C++ Cry | :((

and I was wondering how to get processor serial num in C++ . Now I've found some examples, which return empty 0 serial number in C++ (on my computer), because "the feature is not enabled (on my MB probobly)" . However, when I try to get processor ID in C# using

ManagementObjectSearcher proc_info = new ManagementObjectSearcher("SELECT ProcessorID FROM Win32_Processor");

it does return a value. Does anybody know what is that value representing ?

Intel used to maintain an application note (# 485) that says it all;
assuming they still do (and not just provide a tool to run on a PC)
you should Google for it.

It refers to some assembly code, so you would probably need to create
a C/C++ dll and P/Invoke it.

Smile | :)

That's not really a good idea. I know in all of my machines around here, the ProcId is turned off. It returns 0 in all cases. Can your licensing scheme handle that possibility?

After some research on this topic, i've changed my mind and instead of processorID , I'm using manufacturer and processor type specifications, which are not unique, but on combination with some other id's create "enough" unique identifier Smile | :)

. I hope

thanx for reply

That's the trick. You have to grab a bunch of data from all over the place and combine it to get a uniqueness that you can use. Each piece, in and of itself, might not be unique for a certain sampling of machines, but bits and pieces from all over a machine can't be the same everywhere, statistically anyway.

You have to look at all kinds of stuff like Processor type, RAM data, hard drive and serial numbers, network card MAC's, volume serial numbers, machine SID's, admin account SID's, ..., the list goes on and one.

But, the problem you run into is that your algorithm must be able to withstand changes in the hardware and still return a valid ID.

Sorry, I as a customer do not like that; my machines evolve, and I want to know
beforehand whether my next change will break some of my programs. And anyhow,
I want to continue to use the software I bought on one machine, whatever
happens to that machine; even after a full replacement. Without hassle.

If you have fixed the roof, then added a room to your house, would you like your front door to suddenly remain shut when you repaint the kitchen ?

The one software protection scheme that seems acceptable to me is a hardware
key (today that would be a USB device, plus a backup) that can hold a large
number of keys, so you pass the device's serial numbers to the SW vendors,
and get personalized keys in return.

You're preaching to the choir here! I can't stand Microsoft's little scheme any more than you, and I did mention the drawbacks in my post. It's up to him to figure out a way to do it without screwing the customer if they make a change to the machine.

I really hate protection schemes to begin with. Granted, we need to protect our income, but it's a blurry line between the cost of protection and the margin of profit.

hello forum, well here i m in problem of generating table of content(which is msword feature to generate indexes).

What i have done till know is i generated 2 styles in c# code and apply to word document generated.

Now whats my problem is i have to add these styles to my table of contents ADD method, which requires parameter "ADDEDSTYLE' if new style is to be applied.
i m attaching the code for addingStyle
Word.TableOfContents sty;

object StyleMain = "Main";
object StyleSubMain = "SubMain";
short lev1 = 1;
short lev2 = 2;
sty.HeadingStyles.Add(ref StyleMain, lev1);
sty.HeadingStyles.Add(ref StyleSubMain, lev2);
object stylee = sty;
myWordDoc.TablesOfContents.Add(myWordApp.Selection.Range, ref missing, ref missing, ref missing, ref missing, ref missing, ref RightAlignPageNumbers, ref missing, ref stylee, ref UseHyperlinks, ref missing, ref UseOutlineLevels);

DataBinding of enum property from COM library

Hi all
I have problem, what seems like a bug in C#

I need to bind an property of COM object with enum type to ComboBox.

examp:

<br />
   <br />
        public class CBItem<br />
        {<br />
            public CBItem(ComLib.TypeEnum Type, string Name)<br />
            {<br />
                _type = Type;<br />
                _name = Name;<br />
            }<br />
<br />
            ComLib.TypeEnum _type;<br />
            string _name;<br />
<br />
<br />
            public ComLib.TypeEnum Type { get { return _type; } }<br />
<br />
            public string Name { get { return _name; } }<br />
        }<br />
<br />
...............................<br />
<br />
           this.comboBox1.DataSource = new List<CBItem>(new CBItem[] {<br />
                new CBItem(ComLib.TypeEnum.enOne, "One"), <br />
                new CBItem(ComLib.TypeEnum.enTwo, "Two")<br />
           });<br />
<br />
           this.comboBox1.DisplayedMember = "Name";<br />
           this.comboBox1.ValueMember = "Type";<br />
<br />
           /*<br />
               myComObject is com object <br />
               have properties:<br />
             <br />
               ComLib.TypeEnum Type<br />
               string Name <br />
           */<br />
            //Now bind this property to SelectedValue of comboBox]<br />
            this.comboBox1.DataBindings.Add("SelectedValue", myComObject , "Type");<br />
            //Get exception [Can't bind Type property!!!!!]<br />
            //But if i bind another property alll work fine<br />
            this.comboBox1.DataBindings.Add("SelectedValue", myComObject , "Name");<br />
<br />
<br />

I have a way to avoid this problem by wrapping of COM object like this:

<br />
  <br />
  public class ComWrap<br />
  {<br />
     public ComWrap(ComLib.ComObj ComObj)<br />
     {<br />
         _comObj = ComObj;<br />
     }<br />
<br />
     public ComLib.TypeEnum Type { get {return comObj.Type }}<br />
     <br />
     ComObj _comObj;<br />
<br />
  }<br />
<br />
................<br />
<br />
//This work fine<br />
ComWrap cw = new ComWrap(myComObject);<br />
this.comboBox1.DataBindings.Add("SelectedValue", cw, "Type");<br />
<br />
<br />
<br />

There is more elegant way to awoid this pertrub (with out using of auxiliar wrapper)?
and may be someone can point out why this occur.

hello all currently iam working on the project robotic arm and iam using hitec servo-422 and atmel 8051 microtroller and max 232 and i want to program it in C# to control the robotic arm to pick one object and put it another iam new in C# and i dont have any idea wht do to do please help any one ..could any one provide with any open source,links ..it will be really great and thnx in advance and also i need help wht design pattern i should use.

Why are you expecting the control of a robot to be an appropriate first project ? If you have experience in another language, you should use that, and if you don't, then you probably don't have much hope.

faysie wrote:

I doubt there's a pattern which is going to provide a panacea to your task. It's not typical for a pattern ( unless it's MVC, which is not a GoF pattern ), to define the nature of an entire project.

hey thnx for the reply but new ..means with hardware.. iam in website development already more doesnt mean i dont knw .. Cool | :cool:

..well its more like this but have to code in C# http://www.mavrinac.com/projects/robot/[^] regards therz always hope

Christian Graus19-Apr-07 23:30

19-Apr-07 23:30

Oh, OK. Well, you need to work out how to communicate with your hardware. If the robot uses the serial port. C# 2005 has classes to communicate with that port, so once you work out what you need to send, it shouldn't be too hard.

faysie19-Apr-07 23:43

19-Apr-07 23:43

yes it does work on a serial port ok ....iam getting it but its all kinda mixed up i mean wht will be to exact proecdure to follow to program microcontroller in c# or to program servo motors ..? iam usin rs232 which i serial..can u help me with the exact steps..

Christian Graus19-Apr-07 23:50

19-Apr-07 23:50

I doubt you can program the microcontroller in C#. I'd imagine that would be C or C++.

C# would likely be useful only for writing code on the PC end.

faysie19-Apr-07 23:54

19-Apr-07 23:54

ok now i get it .......so i will be using c++ or c for serial progromming for communicating with the hardware ......u mean microcontroller .with tht servo motors .......is there any ..open source or link which can help

Christian Graus20-Apr-07 1:44

20-Apr-07 1:44

I mean, if you need to program the device, it will probably be C. For a Windows program that controls the robot from the PC, C# will work fine.

No, I've never done this. What about the article you linked to ?

faysie20-Apr-07 4:35

20-Apr-07 4:35

ok tht article i was asking about any article on serial programming is it avaliabe ...anywhere which can be help full tutorial i mean ...cuz tht previous website i mailed the process was exactly like tht ..progammable robotic arm site..

i did some work using an OOPIC controller which connected to my PC via rs232.

Essentially the code was built in 2 parts. there was a stack of code written in OOPIC language and deployed on the controller board. This took care of things like making sure the servos didn't turn too far and the rates at which they moved when commanded. It also had a list of actions that it should carry out and some messages it could send back to the PC.

A winforms app sat on the desktop and sent messages down the wire to the controller.

The user might select straight on from a list of options in a combobox and select 50% on a slider to determine the speed.

The app then sent a message of 1 128 down the serial cable.

The program on the controller knew that 1 meant left and right motors equal and used the next number to be the speed in this case 128/255 of full power.

I guess that's a pattern of a sort. Keep the hardware logic on the controller at the hardware end and the more abstract concepts(go forward, turn slowly, spin on spot) on the computer.

I think serial things have improved in 2k5, i remember 2003 was a bit of a pain for serial coms.
