So that is what the @ is for 
Thank you for your answer, but I have to admit that I screwed up, and the file actually doesn't exist 
I am working with some testdata, and someone placed an error there (possibly on purpose?) 
That is a lot of hours wasted... 
the difference_:

Good day
I am trying to serialize/deserialize a class (for the first time), and the serialization works fine, but as soon as I try to deserialize it, it gives me the exception:
System.Reflection.TargetInvocationException was unhandled
Message="Exception has been thrown by the target of an invocation."
Source="mscorlib"
InnerException: System.Runtime.Serialization.SerializationException
Message="Member '' was not found."
Source="mscorlib"
at Trainer.BoostedClassifier..ctor(SerializationInfo info, StreamingContext context)
The class I'm serializing contains a List<int> type, could this be the source of the error?
I would appreciate any ideas to what this exception might be hinting at. (let me know if more info is needed)

Sorry, I forgot to mention why my heading is called serializing an inherited class;
My class I am serializing also contains a list of my own object type (List<Object>), but the objects themselves are inherited instantiations.
In other words, I'm serializing:
MainClass <-- being serialized. Which contains,
List<Object> <-- where an the objects are of type,
InhertiedObj : Object
If that makes any sense?
I would post the code, but it is unfortunately very long.

Hi,
I have a form that gets data from DB,
i created an event when the form deactivate the current form gets this.Hide() and a new form is open.
my problem if how i can reopen the first window?
if i write-
FirstWindow frmFirst = new FirstWindow();
frmFirst.Show();
a new form is open, but not the first form (the one that i turn to Hide()).
How can i solve this????

You will have to either
1) Keep a reference to the original form and pass it to the new form when you create it, and before you hid the original.
or
2) hook into an event from the second form to the original form which causes the original to re-display itself.
The second is better practice as it doesn't require form2 to know anything outside itself - it just throws an "I'm done" event.
Niether is too complex, the second is a few extra lines of code.

answer:
main Form
this.Hide();
MiniForm frmMini = new MiniForm( sender);
frmMini.Show();
frmMini.TopMost = true;
SubForm:
private void MainForm_Deactivate(object sender, EventArgs e)
{
this.Hide();
MiniForm frmMini = new MiniForm( sender);
frmMini.Show();
frmMini.TopMost = true;
}
private void MiniForm_Click(object sender, EventArgs e)
{
this.Close();
frmMain.Show();
}

So whats the problem?
In the button click event, get the info from the selected cell of the grid, and put it in the text box.
Which bit are you having difficulty with? What have you tried?

Write a button click event handler, hooked to your button.
In the handler, write the code to:
1) Find the selected cell in your grid.
2) Get the text from the cell.
3) Put the text into your TextBox.
At least two of these are simple, one-line-of-code-at-the-most bits of software.
What have you tried?

OriginalGriff is Correct, if you want to edit the gridview in ASP.net, you must enable the appropriate properties that will show you the edit,Delete and update per row and if you click on Edit,you do not need to write a code to do that, ASP.NET already will do it for you. The Values will be Presented in a Textbox , and in edit more for you to edit and the Update and Cancel Button will be available options for you.

Hard to tell without seeing the code. Could you post relevant code here?
|

in form1 this code
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
Form2 gv = new Form2();
dd();
this.Hide();
}
private void dd()
{
Form2 ss = new Form2();
ss.Show();
}
sorry i can not write the design of form 1 part but it an user control that represent a .avi video
thanks very much

I believe Form1 is your start-up form. When Application.Run(new Form1()) is executed, it sets the Form1's visibility to true. This happens after your call to this.Hide() in Form1's constructor. This is the reason why first form is still visible.
Are you looking to implement a splash-screen? If yes, this is not the correct method. Try the following points
- Show the Form1 before the call to
Application.Run - Keep a timer on Form1 with interval as 3secs and when timer ticks, unload the form.
- Instantiate Form2 and start message loop on that.
Application.Run(new Form2()).

HelloNaveenth ,
Thanks for the help.
Can u tell me how to implement Pause and play form the same location
If i pause and then i click play it should play form there only .
I tried with that play method but it is playing from the Start.
Regards,
Phani

I am not sure. Here is what MSDN[^] says
The play method begins playback of the current media item, or resumes playback of a paused item.
|
|
|
|
|
MemoryStream stream = new MemoryStream(); VisitorPhoto1.Image.Save(stream, System.Drawing.Imaging.ImageFormat.Jpeg);
byte[] pic = stream.ToArray();
error on second line......... pls help me thanks in advance
