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.

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?

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;
}
}
}

Excuse-me for my stupid question, In WebForm, I would like to create a button that allow to open html page.(link with parameter ex: qsdf.asp?Text=tete) in the same browser (and other browser). How can I do that?

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 />
}
Note: code was written from memory, it is meant only for a guide

Sorry I tested and you code don't work, I modify your in this manner Response.Write("<javascript>window.open(\"www.codeproject.com\"); ")");
but it is not enough..

I"m curious..
I'm changing settings in my machine.config so my web service runs properly. Problem is .. I can't tell which configuration change is making it work properly. It seems to me like the machine.config file is being cached.
Is it? if so is there a way to prevent it from being cached ?

Hey there,
When using Form.Close and you try to show the form again, it shows without a Titlebar
How do you close a form knowing that you will want to load the form again at a later stage?
|
|
|
|
|
form.Hide() / form.Show()
or
after Close/Dispose, use new Form().
Who is this miscrosoft, and what devilish plans have they for us?

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)
{
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.

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

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.
