Status bar? What status bar?

Are you talking about the System Tray on the Task Bar?

(live/real time processing) and view (the captured
video and the video after processing)
-------------------------------------------------------
EXAMPLE:

filter the RESULTANT FRAME using median filter

all this will be applied for each fame in real

If you are using C++ ,then you may ask it there at its forum,if you are using .NET ,then I believe that the Managed DX SDK[^]will help.

There are some Diffrence :
Title bar is the one that Holdes the title of the window ,and holdes the Close button,The menu is that holdes File,Edit,etc...
So if you want that MENU so you can make a custom one to stand with the Borderless form.

Hello,

I'm trying to differentiate between left and right buttons in my DoubleClick handler for a ListView. The EventArgs argument contains no info, and I couldn't find anything in help.

Any ideas?

Try using a flag in the Click event NOT DoubleClick,and in it know what button has been pressed and then manage this flag.

No, that won't work. The Click event has the same information as DoubleClick: none. I ended up using MouseDown, which contains in its event arguments both the button and the number of clicks (to detect a double click). But thanks anyway! Smile | :)

Don't worry. I was trying to avoid messing with the double click time and all that to tell double-clicks apart from single-clicks, and that's why I didn't want to use MouseDown. But conveniently MouseEventArgs contains a very useful Clicks property Big Grin | :-D

Re: simple ping class request( non console)

If you followed thie link from the last answer you got, that code works fine. It more than likely has to be modified to work exactly how you want it and return the information you want.

You're not looking for "100% working correctly", the code in the example works.

You're looking for "100% working the way I want it to". Modify the code correctly, and it will.

In brief...I've a MDI application with this MDI childs(at the moment all MDI childs are closed):
1)MDIFORM (MDI container)
2)FORM1 (MDI form child)
3)FORM2 (MDI form child)
I press a menu on MDIFORM that opens FORM1.

In FORM1 there is a texbox.
On keyPress event of textbox I write in a MSAccess table what I'm writing in the textbox.
On Load event of FORM1 I open FORM2 where is a datagrid.
The code is:

public class FORM1: System.Windows.Forms.Form
{
private FORM2 form2=null;
private void FORM1_Load(object sender, System.EventArgs e)
{
if (this.form2==null)
{
this.form2=new FORM2();
this.form2.MdiParent=this.MdiParent;
}
this.form2.Show();
}
private void InsertString(object sender, System.Windows.Forms.KeyPressEventArgs e)
{
// -- INSERT DB
}
}

In FORM2 I've a datagrid where I show results written before in last MSAccess table.The code is this:

public class FORM2 : System.Windows.Forms.Form
{
private System.ComponentModel.Container components = null;
private System.Windows.Forms.DataGrid dataPreResult;

public FORM2()
{
InitializeComponent();
}

protected override void Dispose( bool disposing )
{
if( disposing )
{
if(components != null)
{
components.Dispose();
}
}
base.Dispose( disposing );
}

#region Windows Form Designer generated code
private void InitializeComponent()
{
this.dataPreResult = new System.Windows.Forms.DataGrid();
((System.ComponentModel.ISupportInitialize)(this.dataPreResult)).BeginInit();
this.SuspendLayout();
//
// dataPreResult
//
this.dataPreResult.AllowSorting = false;
this.dataPreResult.BorderStyle = System.Windows.Forms.BorderStyle.FixedSingle;
this.dataPreResult.DataMember = "";
this.dataPreResult.Dock = System.Windows.Forms.DockStyle.Fill;
this.dataPreResult.Font = new System.Drawing.Font("Verdana", 8.25F, System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Point, ((System.Byte)(0)));
this.dataPreResult.HeaderForeColor = System.Drawing.SystemColors.ControlText;
this.dataPreResult.Location = new System.Drawing.Point(0, 0);
this.dataPreResult.Name = "dataPreResult";
this.dataPreResult.ReadOnly = true;
this.dataPreResult.RowHeaderWidth = 10;
this.dataPreResult.Size = new System.Drawing.Size(232, 613);
this.dataPreResult.TabIndex = 0;
//
// FORM2
//
this.AutoScaleBaseSize = new System.Drawing.Size(5, 13);
this.ClientSize = new System.Drawing.Size(232, 613);
this.Controls.Add(this.dataPreResult);
this.Location = new System.Drawing.Point(600, 10);
this.MaximizeBox = false;
this.MinimizeBox = false;
this.Name = "FORM2";
this.ShowInTaskbar = false;
this.StartPosition = System.Windows.Forms.FormStartPosition.Manual;
this.Load += new System.EventHandler(this.StringPreResult_Load);
((System.ComponentModel.ISupportInitialize)(this.dataPreResult)).EndInit();
this.ResumeLayout(false);
}
#endregion

public void StringPreResult_Load(object sender, System.EventArgs e)
{
ReadResults();
}

public void ReadResults()
{
OleDbDataAdapter da = new OleDbDataAdapter();
OleDbConnection con =new OleDbConnection();
OleDbCommand cmd = new OleDbCommand();
DataTable dt =new DataTable();
dt.Clear();
con.ConnectionString=<connectionstring>;
con.Open();
cmd.Connection = con;
cmd.CommandText = "SELECT * FROM TABLE";

da.SelectCommand = cmd;
da.Fill(dt);

dataPreResult.SetDataBinding(dt,"");

cmd.Cancel();
con.Close();
}

}

So now, my problems is: how can update datagrid in FORM2 from FORM1 when I call keypress event on FORM1 textbox(InsertString in example code)?

Thanks for any help!!! Big Grin | :-D

Uh...What you need to do is maybe set a timer in form 2 to refresh the data in the datagrid..
I have an app that I do something similar in, and all you need to do is call ReadResults() and do dataPreResult.Invalidate() (to make sure that it gets redrawn) every so often..I'm not 100% sure on that, but it should work.

Here's the relevant code:

Timer updateDataGrid = new Timer(); // add this to your object declarations<br />
<br />
public FORM2()<br />
{<br />
	InitializeComponent();<br />
	updateDataGrid.Interval = 60*1000;<br />
	updateDataGrid.Tick += new EventHandler(doUpdate);<br />
	updateDataGrid.Start(); // add the above 3 lines in the constructor to set the interval, the 				    handler for the timer firing and to start it. updating every minute 					    seems like a good time, but you can change that<br />
}<br />
<br />
private void doUpdate(object sender, EventArgs e)<br />
{<br />
	ReadResults();<br />
	dataPreResult.Invalidate();<br />
}
