Not all colors have names. Exclamation mark.
There are about 140 colors that have names and over 16 million colors that doesn't have a name.
But if you like, you can sit down and name them all. I'll help you with the first:
#000000 Black
#000001 BlackWithAnInvisibleHintOfBlue
#000100 BlackWithAnInvisibleHintOfGreen
#010000 BlackWithAnInvisibleHintOfRed
#000101 BlackWithAnInvisibleHintOfCyan
#010001 BlackWithAnInvisibleHintOfMagenta
#010100 BlackWithAnInvisibleHintOfBrown
#010101 BlackWithAnInvisibleHintOfGray
#000002 BlackWithASlightlyLessInvisibleHintOfBlue
#000200 BlackWithASlightlyLessInvisibleHintOfGreen
#020000 BlackWithASlightlyLessInvisibleHintOfRed
Now it's only 16777205 more to go. Good luck and have a happy life time inventing color names...

Colours are made up of 3 components (R,G,B) which can range in value from 0 to 255
255,0,0 Is called Red
254,0,0 has no name
etc
0,255,0 is called green
etc
etc
In html a colour can be represented as Hexadecimal, which is just the r,g & b numbers converted to hexadecimal. Search for how to convert decimal to hexadecimal - it is very easy.

hi guys,
im using c#.. how can i get the hostname of a client pc from the server appliction in my network? i have no problem getting the IP address but i can't get the hostname... tnx in advance..

I think the GetHostbyAddress() method can help you.
the followed code is copyed from msdn:
try
{
IPAddress hostIPAddress = IPAddress.Parse(IpAddressString);
IPHostEntry hostInfo = Dns.GetHostByAddress(hostIPAddress);
// Get the IP address list that resolves to the host names contained in
// the Alias property.
IPAddress[] address = hostInfo.AddressList;
// Get the alias names of the addresses in the IP address list.
String[] alias = hostInfo.Aliases;
Console.WriteLine("Host name : " + hostInfo.HostName);
Console.WriteLine("\nAliases :");
for(int index=0; index < alias.Length; index++) {
Console.WriteLine(alias[index]);
}
Console.WriteLine("\nIP address list : ");
for(int index=0; index < address.Length; index++) {
Console.WriteLine(address[index]);
}
}
catch(SocketException e)
{
Console.WriteLine("SocketException caught!!!");
Console.WriteLine("Source : " + e.Source);
Console.WriteLine("Message : " + e.Message);
}
catch(FormatException e)
{
Console.WriteLine("FormatException caught!!!");
Console.WriteLine("Source : " + e.Source);
Console.WriteLine("Message : " + e.Message);
}
catch(ArgumentNullException e)
{
Console.WriteLine("ArgumentNullException caught!!!");
Console.WriteLine("Source : " + e.Source);
Console.WriteLine("Message : " + e.Message);
}
catch(Exception e)
{
Console.WriteLine("Exception caught!!!");
Console.WriteLine("Source : " + e.Source);
Console.WriteLine("Message : " + e.Message);
}
Just do it!

Hello everyone,
I have a DataGridView in a windows form with three columns:
Column1 is TipoComboBoxColumn
Column2 is QuantidadeColumn
Column3 is SementeComboBoxColumn
I need the SementeComboBoxColumn to display values according to the value I select in the TipoComboBoxColumn.
How do I go about accomplishing that? The code below works in part, BUT when I'm editing the value of SementeComboBoxColumn, the other values for the other rows in this column disappear. This is driving nuts!
private void tabBAdetDataGridView_CellClick(object sender, DataGridViewCellEventArgs e)
{
if (tabBAdetDataGridView.Columns[e.ColumnIndex].Name == "EspecieComboBoxColumn")
{
this.tabSementesTableAdapter.FillByTipo(this.sascrDataSet.tabSementes, tabBAdetDataGridView.Rows[e.RowIndex].Cells["TipoComboBoxColumn"].Value.ToString());
this.EspecieComboBoxColumn.DataSource = this.tabSementesBindingSource;
this.EspecieComboBoxColumn.DisplayMember = "Semente";
}
else
{
this.tabSementesTableAdapter.Fill(this.sascrDataSet.tabSementes);
this.EspecieComboBoxColumn.DataSource = this.tabSementesBindingSource;
this.EspecieComboBoxColumn.DisplayMember = "Semente";
}
}
Thanks in advance,

Hello everyone,
Here's the scenario: I have three windows forms (frmMain, frmClients, frmOrders).
There's a button on frmClients that opens frmOrders.
Now, the question is: What's the code on frmClients to define that the frmOrders' MDIParent is frmMain?
Thank you very much for your time and help,
JC Carmo.
|
|
|
|
|
hi,if you declare frmOrder's MDiparent as frmmain,
then you cannot show frmOrder just like that.
you have to show the mdiparent of the formorder and then show formorder.
the code inside the button will be like
Order frm = new Order ();
FrmMain frmMain = new FrmMain();
frmMain.Show();
frm.MdiParent = frmMain;
frm.Show();
but infrmmain, the IsMDIContainer property should be set to true.
try this.
all the best.

Hi,
u can simply write
frmOrders.MDIParent = this.MDIParent;
Hope that works for u

I am having trouble finding anything on this topic. I have a System.Windows.Forms.WebBrowser control on my windows form. In it there are some links. When the user clicks a link I want it to fire an event back in the windows form. Any help on how to do this would be appreciated.
Thanks

I'm creating a program that I need the context menu to show up automatically on load. I tried contextMenuStrip1.Show(this, 5, 5);, but it hides right away. Is there anyway that I can make it stay open until the mouse moves away from it or clicks away?

try this
ContextMenu menu = new ContextMenu();
MenuItem item = new MenuItem("test");
menu.MenuItems.Add(item);
menu.Show(this,new Point(10,10));

Looks like that works for ContextMenu, but not for ContextMenuStrip. Any ideas?

Ok My problem is i don't know how to make a form modal. I know how to show them modelessly with Show() but as far as displaying them as modal im lost.

.ShowDialog() is what you're looking for. You can even get a return value (DialogResult) if you set it up right.
