You could look for the OnSessionEnd Message by over riding WinProc. Then programticly cause the application to close.

Hope this helps....

Thanks for that, seems like a possible solution but....

I've been looking at an example for overriding the WinProc and it seems
easy enough. The message ID is stored in the .Msg property.

Is there somewhere that lists all of the different windows messages and their equivelant .Msg values?

Cheers

All of the windows messages are stored in the Windows SDK Header files.

Here is a link

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/sysinfo/base/wm_endsession.asp[^]

Here is the one you need

it is located in WinUser.h

private const int WM_ENDSESSION = 0x0016

Hope this helps...

hi,

I am executing a select() method agnest a data table. I got result as DataRow[]. Here i got collection of datarow.
My question is how can i create a table from this DataRow[] without executing all unwanted iteration(iterating through individual datarow or something).

Specifically : How can i create a table from a DataRow collection. Confused | :confused:

Hi
If the result is the type of 'DataRowsCollection' then you can directly assign it to DataTable's Rows property.
If it is a collection of DataRows then you have to iterate one by one

hi,

I think you didn't understood my question. See i don't want to iterate through any row hell. Do you have any other solution for this ?

Hi Sreejith

There is no other way.But we can minimize the work in iteration.

SqlConnection con=new SqlConnection(@"Data Source=YOURSERVER\INSTANCENAME;Initial Catalog=Northwind;UID=sa; PWD=sa;");

con.Open();

SqlDataAdapter adpt=new SqlDataAdapter("select OrderID,CustomerID,EmployeeID from orders",con);

DataTable dt1=new DataTable();

adpt.Fill(dt1);

DataRow[] dr=dt1.Select("customerid='vinet'");

DataTable dt2=new DataTable();

for(int i=0;i<dr.GetLength(0);i++)
{

dt2.ImportRow(dr[i]);

}

int a=dt2.Rows.Count;

------------------------------------

try this.

multiple selection in datagrid

hi,

What is your real requirement ?. We can select more than one record in a datagrid. Select() method is used to select a perticular row. And Unselect() method doing the reverse of Select(). you can check whether a perticular row is selected or not by using IsSelected() method. I recommand you to read the DataGrid Class description in MSDN.;)

Hello Sreejit,

I have used DataGrid_MouseUp() event and then used DataGrid.CurrentRowIndex to get the current row.

private void DataGrid_MouseUp(object sender, System.Windows.Forms.MouseEventArgs e)<br />
		{<br />
int i = DataGrid.CurrentRowIndex;<br />
}

But how can I get multiple rows index if I have selected multiple rows.
like this>>

private void DataGrid_MouseUp(object sender, System.Windows.Forms.MouseEventArgs e)<br />
		{<br />
 for (int i = 0; i <= DataGrid.CurrentRowIndexes:confused:; i++)<br />
      {<br />
      int j = DataGrid.CurrentRowIndexes[i];<br />
          }<br />
}

//For collecting the index of selected records
ArrayList Ar=new ArrayList();

private void DataGrid_MouseUp(object sender, System.Windows.Forms.MouseEventArgs e)
{
for (int i = 0; i <= DataGrid.CurrentRowIndexes; i++)
{
/*this line will help you to deside whether row is selected or not. If yes then it will return a bool value. Else will return a false value.*/

if(DataGrid.IsSelected(i)

Ar.Add(DataGrid.CurrentRowIndexes[i].ToString());
else
continue;
}
}

So finally you will get all index of selected row in your ArrayList.

Remaing is upto you to design based on your requirement.;)

How to detect "play some particular .wav file" event?

RodionMrt19-Sep-04 15:09

19-Sep-04 15:09

Hi, I wonder if it is possible to detect somehow (from C# app) when the Windows plays some specific .wav file?
What I wanna do is to "subscribe" for that event and do my job when some specific .wav file gets played.
Any ideas?

thanks!

You're most likely going to be able to do this simply by a mechanism that watches if a file is read, as opposed to played specifically.

I got it to copy, my question is that why it still looses format.

Storing Info:
IDataObject d = Clipboard.GetDataObject();
//d.SetData(DataFormats.Rtf, true, richTextBox1.Text);
// d.SetData(DataFormats.Rtf, richTextBox1.Rtf);
Clipboard.SetText(richTextBox1.Text, TextDataFormat.Rtf);

Retriving info:
foreach (Word.Shape bkMark in aDoc.Shapes)
{
if (bkMark.TextFrame.TextRange.Text.Contains("heading"))
{

// bkMark.TextFrame.TextRange.Paste();
bkMark.TextFrame.TextRange.Text = Clipboard.GetText(TextDataFormat.Rtf).ToString();
//Clipboard.GetDataObject().GetData(DataFormats.Text).ToString();
//
//

}

}

bkMark.TextFrame.TextRange.Text contains plain text by definition, if you want formatted text you'll have to use clipboard pasting.
To have control over what will actually get pasted you'll have to specify that you want RTF. IIRC there's a PasteSpecial (or something similar) where you can tell Word what format to paste.

Winforms: ListView: getting the label edit control

peterchen19-Sep-04 9:10

Hi,

I have a list view control with Label Edit Style.

When the user presses a key while an item is selected, Editing should start immediately.
I catch the KeyPress notification and enter edit mode, but I also have to set the edit's contents (or send the simulate the key event).

For that, I think I need the Edit control itself. Is this possible?
