How big/long is the mp3 file?

If it isn't too big, I'd suggest converting it to a wave file, then using the SoundPlayer class[^] to play it.

Note that the filesize will increase when converting from mp3 to wav.

If you insist on keeping the file as an mp3, have a look at this article:
MP3 Player for Windows 7[^]

hi friends,

i am using xmlclass serailization to read the Xml File

///<Order xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" orderId="1" version="3.1.0" xmlns="http://www.abc.com/schemas/imaging/rps/order/2007/01/" ///>

</order>

XmlTextReader reader = new XmlTextReader(filename);

try

{

XmlSerializer serializer = new XmlSerializer(typeof(Class_name));

Class_object = (Class_name)serializer.Deserialize(reader);

reader.Close();

}

catch (Exception e)

{

reader.Close();

return;

}

it says that "{<Order xmlns='http://www.abc.com/schemas/imaging/rps/order/2007/01/>' was not expected."}"

my class defination is as follows

[XmlRoot("Order")]

public class Class_name

{

[XmlAttribute]

public string orderId;

[XmlAttribute]

public string version;

//default constructor

}

}

Can Anyone help me to resolve this!!

Passing Value From One Form To Another! [modified]

Hi,
I am trying to pass value from one windows form to another in desktop application using C#.
I have created two text boxes on Form1 and a button, on button click I am creating Form2 and From2 contains one button, on this button click I have to pass value from Form2 to Form1 textboxes.

I have created Properties in Form1.

public string Emp
{
get
{
return strEmp;
}
set
{
strEmp = value;
}
}

public string EmpID
{
get
{
return strEmpID;
}
set
{
strEmpID = value;
}
}

And on Form1 button click:

private void button1_Click(object sender, EventArgs e)
{
Form2 fr = new Form2();

this.textBox1.Text = strEmp ;
this.textBox2.Text = strEmpID ;
fr.ShowDialog();
}

On Form2:

private void button1_Click(object sender, EventArgs e)
{
Form1 fr = new Form1();
fr. Emp = "Alex";
fr. EmpID = "1121";
this.Close();
}

This code is not working, Please let me know where I am wrong.

Thanks,

First there is a compilation error at the 2 statements in which you are assigning variables to the textbox as name of the variables differ.

Second, you are setting the values in the text box of first form after calling the showdialog. So, the values can e displayed only after you close the dialog box.

Third, You are creating a new instance of form1 on the click of button on form2. It won't set the values on the initial form.

Repositioning the cursor

Hello,
I am looking for ways to reposition the cursor when I am clicked on the first menu item from a form menu. It should create a jumping effect so the user doesn't have to scroll through the other menus which don't have a child menu.

for example.... one file menu has 4 items. Namely 1, 2, 3, 4 now only item 2 has child menu items. namely 2.1, 2.2, 2.3. I want the cursor to be on 2.1 when the user brings the mouse on 2.

Please let me know how to do that. I am trying the following:

private void toolStripMenuItem2_MouseHover(object sender, EventArgs e)
        {
            toolStripMenuItem2.ShowDropDown();
            Point LocalMousePosition_1 = this.PointToClient(Cursor.Position);
            System.Windows.Forms.Cursor.Position = new Point(500, 500);  //This just repositions the cursor to 500,500 position but not in the net child menu. This is where I am stuck.

            //Point LocalMousePosition_2 = toolStripMenuItem2_1.PointToClient(Cursor.Position);
            MessageBox.Show(LocalMousePosition_1+"Happy New Year to DOTNETSPIDER.COM guys");        
        }

That sounds user-hostile -- I wouldn't use your application if it did that.

Easy now skhan17, no need to get all personal and stuff... hi just posted his opinion...

But here try this:

System.Windows.Forms.Cursor.Position = [MenuItem2.1].PointToClient();

One thing here to remember is, that you CANNOT call this before the [MenuItem2.1] has been shown. Wink | ;)

Hope it works

With great code, comes great complexity, so keep it simple stupid... $Shucks | :-\$ $Shucks | :-\$

well it doesn't let me add that... i have tried that... it says :

Error 1 'System.Windows.Forms.ToolStripMenuItem' does not contain a definition for 'PointToClient' and no extension method 'PointToClient' accepting a first argument of type 'System.Windows.Forms.ToolStripMenuItem' could be found (are you missing a using directive or an assembly reference?)

I am sure that the child menu item has been shown before that.... please help....

Thanks for replying......

Hi,
Handle the DropDownOpening or DropDownOpened event that occurs when your child menu appears. The Location property will get the screen coordinates of the top left corner of the menu. Apply an offset to put the cursor into the centre of the first menu item.

private void MenuItem_DropDownOpening(object sender, EventArgs e) {
  ToolStripMenuItem menu = (ToolStripMenuItem)sender;

  Point p = menu.DropDown.Location;  // screen coords
  Rectangle r = menu.DropDown.Items[0].Bounds;
  p.Offset(r.Width / 2, r.Height / 2);
  Cursor.Position = p;
}

Alan.

THANK YOU SO MUCH..... although I have figured out a manual way.... but this works like a charm....

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
