I've just started playing with c# and created a simple control which inherits the textbox control.
I can hide all properties relating to multilines as the control will never do this, by overriding the property and setting [Browsable(false)].
My question is, is there a way to also stop intellisense picking up these hidden properties, eg
usrTextBox.AcceptsTab cannot be seen on the properties page but can be pickup up within the body of the code using usrTextBox.?????
Thanks

Is it possible to tell if a control is being designed by the windows form designer? As i will need to render it differently in that situation.

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
/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;
}
}
}
