Hello,
I'm new to C#.NET programming and I have little knowledge on C++. I'm trying to write a project which will convert a decimal number to hex and hex to decimal. I tried "Convert.ToInt" but couldn't get the result.

If anyone would help me about this problem, I would be appreciate it very much.

Thanks!

This should work:

string ToHex(int number)
{
    return number.ToString("X");
}
 
int FromHex(string number)
{
    return int.Parse(number, 
        System.Globalization.NumberStyles.HexNumber);
}

I've got one that I wrote a while ago using straight C++ so I was thinking of porting either it or Tidy - but was hoping someone else had done the legwork before me.

Tooltip like window?

31-Jan-03 3:22

Hi , ive asked this before , but does ANYONE know how to make a borderless window behave like a tooltip?
meaning , it should not steal focus from the app that shows it (grayout the apps caption)

i need to be able to place controls on the 'tooltip' but they dont need to be able to hold focus , just as long as i can click them and the click events work...

currently im doing some nasty wndproc hack , scanning for the wm_ncactivate message , and setting focus back to the parent window... but this causes the parents caption to redraw , so there is some minor flicker (but still annoying)

any idea?

//Roger

If you're using Windows 2000 or higher, you can override the CreateParams property, and add WS_EX_NOACTIVATE to the ExStyle property:

class TooltipForm : Form
{
    ...
    protected const int WS_EX_NOACTIVATE = 0x08000000;
    
    protected override CreateParams CreateParams
    {
        get
        {
            CreateParams cp = base.CreateParams;
            cp.ExStyle |= WS_EX_NOACTIVATE;
            return cp;
        }
    }
}

In your event handler for your Button you can Response.Write your javascript code to load a new window and change the location of your current browser. This gives you a dynamic effect.

js references
window.open, href.location

example:

public void OnClickButton1(object sender, EventArgs e){<br />
  Response.Write("<javascript>window.open("www.codeproject.com");</javascript> );<br />
<br />
}

When using Form.Close and you try to show the form again, it shows without a Titlebar Confused | :confused:

How do you close a form knowing that you will want to load the form again at a later stage?

form.Hide() / form.Show()

Excel automation

Mauricio Ritter30-Jan-03 23:49

Mauricio Ritter

30-Jan-03 23:49

I´m creating an application that does some automation with excel. The problem is that Excel sometimes is busy doing some tasks and can´t respond to my method calls. To solve this I´m using something similar to this;

while(true)
{
  try
  {
      oWorkbook.Range(...);
  }
  catch(System.RunTime.Interop.COMException)
  {
    // wait a littel bit
    System.Threading.Thread.Sleep(100)
  }
  catch(Exception exp)
  {
      throw(exp);
      break;
  }
}

The problem is that I have TONS of this oWorkbook.Range(...); lines... and I don´t want to write this bunch of code to all of them. Does anyone know some alternative way to do this (some kinda template maybe) ? I know I can write a wrapper to do this... but it´ll give me a lot of work... and I´m trying to find a better solution.

Can't get MAC address using ManagementClass

EnkelIk30-Jan-03 21:15

EnkelIk

30-Jan-03 21:15

I've written a small app that retrieves the MAC-address from computors, using ManagementClass, ManagementObjectCollection and so on, eventually ManagementBaseObject.get_Item("MacAddress"); which turns out to work fine for most computors. Lately however I have discovered that for some computors a different series of numbers is retrieved. Looking into it a bit deeper I found that on all computors not one, but serveral items could be found calling get_item("MacAddress"). So my program did work for computors where the real MACaddress was the first to be returned (and apparently this included most computers).

Have I missed something? How can I tell which one is the real MAC address, and what are the other numbers?

Kind regards
/EnkelIk

Below a snippet of my code:
ManagementClass mc;
ManagementObjectCollection moc;
ManagementBaseObject mbo;
ManagementObjectCollection.ManagementObjectEnumerator moe;
string strMAC="",strTmp;

mc = new ManagementClass("Win32_NetworkAdapterConfiguration");
moc = mc.GetInstances(); // Get network adapter instance

moe=moc.GetEnumerator();

//Loop till MAC address found
while(moe.MoveNext())
{
mbo=moe.Current;

if(mbo["IPEnabled"]!=null)
{
Object pObj;

//Get MAC address
pObj=mbo["MacAddress"];
if(pObj!=null)
{
strTmp=pObj.ToString();
strMAC=string.Concat(strMAC,strTmp);

//Remove colon
strMAC=strMAC.Replace(":","");
break;
}
}
}

The answer is often simple when you know it... Debugging more carefully I found that mbo["IPEnabled"] is a System.Boolean -it is either true or false, but never null. Smile | :)
