Why bother, there are some classes built into .NET to do this for you. I think anyway, never bothered much with help.
Formula 1 - Short for "F1 Racing" - named after the standard "help" key in Windows, it's a sport where participants desperately search through software help files trying to find actual documentation. It's tedious and somewhat cruel, most matches ending in a draw as no participant is able to find anything helpful. - Shog9

I want to find out if an excel file (Let us say "c:\ABCD.xls")is currently open.
I am using c# and Excel Interop.
Thanks

Try to open the file exclusively. If an exception is returned, it's in use.

i have a listview in my program and whenever the item is checked or unchecked i want certain things to happen. how can i accomplish this without the item checked event handler taking over every time i add an item to the listview?

Those statements contradict each other. Unless you mean that the CheckChanged or what ever it's called event is being fired when you add an item to the list view?

ok say i have a list of items in the listview, when i either check or uncheck them i want certain things to happen. but if i add an item to the listview, it fires the event handler as if i checked or unchecked an existing item and i want to block it from doing that.

How about when you add an item to the list view use the "Tag" property to indicate that it's just been added and thus ignore it later in the code:
private void AddItemToList()
{
ListViewItem lvi = new ListViewItem("New Item");
lvi.Tag = "ItemJustAdded";
this.listView.Items.Add(lvi);
}
private void listView_ItemChecked(object sender, ItemCheckedEventArgs e)
{
if (e.Item.Tag == "ItemJustAdded")
return;
}

You'dthen need to clear the tag either in the handler, or in the add method otherwise checks will be permanantly nonfunctional in new items.

Put your code in the ItemCheck event handler, rather than ItemChecked. ItemCheck does not fire when an item is added.

I think you need to use RichTextBox control. Using RichTextBox, you can set different font for the text
|
|
|
|

You can create a new font with English &Tamil And use it Or you can use RichTextBox.
Thnaks.

So, you want to delay the sending of emails until a determine time?

I dont think you mean to say that you need only 1 connection until all the mails you want to send are handed over ? If this is the case then you might be unhappy that there is no setting which can persist the connection. ( though i havent checked it myself, it is my perception )

yes i meant that.
.send() is a blocking call.
i need to send mails at one go with one connection, this is to get rid of Timeout wait in .Send() which takes place for each Mail that i need to send and if there are too many then its that much of wait for my application,

If it's a problem, why not send it in another thread?

Do they all have the same content?
|
|
|
|

no ,
notifications are per action like Task Created,User registed etc..
if they are same is there way to do bulk send?
thanks,
