You can't do this natively in .NET, you will have to rely on third party SDKs.
Possibly consult the Windows Media Player SDK, Direct X SDK, or google for a SDK.

Good Day,
I have a ListView and I want to display a message box when an item is added.
Is there an EVENT that is being triggered when an item is added into the ListView?
Thanks!
|
|
|
|
|
No there is no event for that.
But it can be done. For example derive from the ListView and define an IBindingList[^]member to create a data bound listview. After that respond to the IBindingList.ListChanged event.
Also there is an article here[^] that discuses something similar.
Hope it helps!

Hi there,
is there a table control can be used in C# form in order to contain data I put during run time ( not data base table)
I need the table to organize the output ( which is some calculations performed by the application,
I read somewhere that there is a table control but must be added and referenced (dll), but I do not how!! 
help is appreciated
thanks in advance
There is always something to learn

[edit: misread table control for tab control]
Their is a table control which can either be a listview with detail view or the grid control. They are both included in the standard System.Windows.Forms namespace.

Hello all,
We are going to start a migration project, i,e from C++ to C#, i do not have any idea on C++ absoultely, there would be many problems while converting pointers, Multiple inheritance in C++ and etc, could anyone help me in providing some information about the issues in converting the C++ code to C# code?

if you want to have a clean result of the C# version, i don't think it can be done the way you have imagined, by converting the pointer, multiple inheritance and so on.
you have to understand first the whole idea what is in the program you want to convert in C++ version, and then redesign it in C# version. but unfortunately for you, you have to understand first the C++ version.

How can you possibly undertake this work if you don't understand C++? Do you seriously expect to gain an understanding of such a complex language from a single forum post?

We produce a product which assists with this (named very creatively as 'C++ to C# Converter'), however as the others have noted it is futile to attempt this if you don't already have a very good grasp of C++. A converter helps with the grunt work, but the most complex aspects of conversion are the areas that often need some manual adjustments and if you don't know C++ you'll have great difficulty ensuring that the original functionality is preserved. Also, some C++ code simply cannot be converted to C#.

I'm reading a text file using a stream read and my code goes like this
<br />
FileStream file = new FileStream("c:/data/theData.txt", FileMode.Open, FileAccess.Read);<br />
StreamReader streamReader = new StreamReader(file);<br />
<br />
String line = streamReader.ReadLine();<br />
<br />
while (line != "")<br />
{<br />
if (line.Equals("<data>"))<br />
{<br />
.....
}<br />
<br />
line = streamReader.ReadLine();<br />
}</data>
the problem is that whenever i run my program, this error occurs on runtime:
"Object reference not set to an instance of an object" and it's pointing at the
"if(line.Equals(""))"... what's wrong? i used to do this in java and it works..

Why are you checking it both ways ? What happens if you step through the code ? Why are you using .Equals ?
File.ReadAllLines is the easiest way to get your file as an array of strings.

As the documentatio states:
"
Return Value
The next line from the input stream, or a null reference (Nothing in Visual Basic) if the end of the input stream is reached.
"
Ordinarily, reading through a text file and doing something with the non-empty lines would be written as:
String line ;
while ( ( line = streamReader.ReadLine() ) != null )
{
if ( line.Length == 0 ) continue ;
.....
}

Thank you this time it worked... I wonder why that first guy who replied keeps on asking why I do this and do that, why does he care?, it's MY PROGRAM.. and I WANT IT THIISS WAYYY... nobody can stop my creativity

Thanks.
Silvyster wrote: keeps on asking why
Because you should be able to read the documentation to determine what the problem is.
Silvyster wrote: it's MY PROGRAM.. and I WANT IT THIISS WAYYY
But your way didn't work very well, did it?

yeah the documentation is like a lot of pages and I believe this website makes things for programmers to learn easier and better. yeah my program didn't work but at least the way you modified it, makes sense. I mean THAT other guy is already giving me alternatives, BUT I dont want alternatives, I want SOLUTIONS

hi, if I use the following code, even if I saved the txt file to Ansi codepage instead of UTF8, the StreamReader sr always gets UTF8 encoding and thus returns [239][187][191] which is UTFS-8 ByteOrderMark value. Ansi or other encodings than UTFS-8 w/BOM should not have those values. Can anyone please help me how to correct this to return correct current encoding of a file?
using System;
using System.IO;
using System.Text;
class Test
{
public static void Main()
{
string path = @"d:\work\ansi.txt";
try
{
if (File.Exists(path))
{
}
using (StreamReader sr = new StreamReader(path, true))
{
byte[] byteordermark;
while (sr.Peek() >= 0)
{
Console.Write((char)sr.Read());
}
byteordermark = sr.CurrentEncoding.GetPreamble();
ShowArray(byteordermark);
}
}
catch (Exception e)
{
Console.WriteLine("The process failed: {0}", e.ToString());
}
}
public static void ShowArray(Array theArray)
{
foreach (Object o in theArray)
{
Console.Write("[{0}]", o);
}
Console.WriteLine();
}
}

I am looking for some suggestions. What I am trying to do is basically update a form every X milliseconds. The example I am working with at the moment is an attempt to report the current mouse position in a text box in a form. I am actually looking for two responses. All of this is mainly for the sake of learning something new, so the details are not really what is important.
Here's an example of what I am doing now:
<br />
while (someCondition)<br />
{<br />
UpdateCursorPosition();<br />
Thread.Sleep(30);<br />
}<br />
Where "UpdateCursorPosition" could as well be "DoStuff".
The problem as you can imagine is that the form would always be unresponsive to user input (for obvious reasons). How can I do this right, so that the window is responsive, and I get a continuous update? As I said, the details are not that important, just the concept.
On a side note (the second question) , is there a way to get an "OnMouseMove" event for the desktop?

You can capture the mouse, and hten you'll get mouse events even when the mouse leaves your form.
You can set a timer and use the method that it calls to check the mouse position.
