The .NET Color struct provides these instance properties: A, R, G, and B. You can use the last three to get the values you need.

That depends on how you want to convert it. The alpha channel (A) contains transparency information.
If you don't use transparency you could just drop that information. If there is transparency information you should draw the image on a solid background so that you get an image without transparency.
An ARGB value is a 32 bit value. You can mask off the top 8 bits to get the 24 bit value for the RGB channels:
int rgb = argb & 0x00ffffff;
---
b { font-weight: normal; }

I have created a listview in my C# form and when i add an item through my code I change the background color of my cells/rows. However, when i scroll over them at runtime the color defaults back to white and then they stay white. I have different tab pages in my form. If I switch to a different tab page and then come back the colors will be back where they were until they are selected or scrolled over again. Is this simply a glitch in VS? I have no idea how to fix it. When I enter items into the listview I am using the following code.
ListViewItem li = new ListViewItem(le.TimeStamp.ToString());
//Allows us to use different fonts, backgroud colors, etc. for individual items within a row on the
//list view and for entire rows themselves
li.UseItemStyleForSubItems = false;
string mt = "";
//depending on the type of message that is being logged to the case tab a color indicator is chosen
//to be displayed in the "Indicator" column
switch(le.MessageType)
{
//display a green indicator bar and a message for "Informational"
case "Informational":
{
mt = "Informational";
li.SubItems.Add(mt);
li.SubItems.Add("");
li.SubItems.Add(le.Message);
li.SubItems[2].BackColor = Color.Green;
CaseLogListView.Items.Add(li);
break;
}

Hi,
I've written a program which stores user data for websites. I would like the user to be able to fill in forms automatically on a webpage based on the data in my program.
I see two possibilities, but don't know if either of the two would work.
1) Drag the relevant text from a textbox in the desktop app to the webform into the relevant field. I can't get the textbox to let me drag the text, though.
2) Automatically insert the text into the webform field which has the focus, whenever the user clicks on a button in the app. Wouldn't know how to approach this one...
Does anyone have any ideas?
Thanks.

Hi
If there is not any button control on winform then forms key press event is fires But if we place button control on winform then focus directly goes to button and keypress event of the form does not get fired.What can be the reason. It can be easily replicated by just writing any code in keypress event of windows form there should not be any control on the form then its keypress will be fired, now just place a button control u will see form's key pressed is not getting fired.
It seems focus issue.Can anyone advice.

In Windows applications, if there is ANY control on a form that CAN receive the focus it does, and the form does not. You are correct, it is a focus issue, and it was designed that way.
HTH explain it anyway. 
|
|
|
|
|
Set the Form's KeyPreview property to true, and it's KeyPress event will fire before the active control's KeyPress.

static class in C# can accept serialization attribute.
like
[Serializable]
static class MyStatic
{
static MyStatic()
{
}
}
compiler will not give error.
But my question is can i serialize static class.if so how i can do?

You can't serialize a class, only an instance. An instance of that class would be serializable, but that is quite useless, as you can't create an instance of the class.
I'm not sure if it's an oversight in the design that a static class can be serializable, or if it's intentional. It shouldn't cause any problem anyway.

I don't think the AttributeUsage attribute provides a way to specify that an attribute can be applied only to non-static classes. That's probably why Serializable can be applied to any class.

You could start by looking up System.Xml.XmlDocument.

Try
Dim ObjXmlDoc As New XmlDataDocument
ObjXmlDoc.Load("file.xml")
Dim objNodeList As XmlNodeList = ObjXmlDoc.GetElementsByTagName (strNodeName)
Dim strValue As String = objNodeList(0).InnerText
Catch ex As Exception
' whatever
End Try

I have used NDoc to create the MSDN format help files for my code, and I saved the file it created,but there is a problem. How can I view the file if I don't have the NDoc?I mean is it possible to view the file on a system which NDoc hasn't been setup on it?Or is it possible to save it with another extension, rather than .ndoc?
Thanks in advance.

The .ndoc file is just something specific to NDoc. It doesn't have your documentation in it. You have to compile the NDoc documentation. It will build either a .chm or a whole directory full of html, depending on your settings (which are stored in the .ndoc file).
