string[] stringArray = {"Hello", "World"};<br />
ListViewItem lvi = new ListViewItem(StringArray);<br />
<br />
if(this.listview1.items.contains(lvi))<br />
{<br />
;
}<br />
else<br />
{<br />
this.listview1.items.add(lvi);<br />
this.listview1.update();<br />
}<br />
Why does this code always run in else block when the same Listview item is added into the listview??

Is it because everytime a new object is created??
What if I want to compare listview items and then add into listviews???`

Because it doesn't. Even if the contents of the two items are the same, they are two different list view items. They just happen to have the same strings in them. You need to search through the strings inside the items, if that is what you mean.

Do u mean to say I need to use the 'SubItem' property..??
Then how do we use listview.contains ?

I'm assuming there's a find method which finds the first item which contains a string, or something like that.

i asked this question here before too but no answer so i m asking again..that i hav a mdi form which displays a mdi-child form on its load event...it contains various functionality..like view the complete detail of the current user of the datagridview...so on opening this view(mdi-child)form it displayed under the mdi-parent form and also shows its menu items like File,Edit,View etc...and also having an edit button..which displays another(mdi-child)form for editing the record..but the problem is this..it is not displaying under mdi-parent form and not showing the mdi-parent's menu item..even it also hides the start menu bar...so please help me how to call a mdi-child form from another mdi-child form

What happens if you create a method on the mdi-parent that opens the edit form? By using this technique the two forms are opened the same way. If you still get the same behavior the problem must be related to how you have set up the two forms.

Well, you need to start experimenting to find the source of the error. Then you can judge if you should try to solve it or try to find another acceptable solution. Just sitting there waiting for answers will get you nowhere.
Another thing you can try is to comment out the line where you set FormBorderStyle.

thanx for suggestion....and telling me the truth

i agree with this.
create your midi forms on the midi parent... always.
if you want to create/call from another midi child, create an event on the midi child, something like "CreateMidiChild", and when the event is triggered the midi parent which will be subscribed to this event can create the new child for you.

What on earth is your question ? What do you mean by service pack ? What do you mean by 'not running' ? Is this even a C# question ?

OK, first of all, when you build an exe, it's NOT called a service pack.
Second, if it doesn't run in vista, you need to work out at what point it fails, and then you can work out why.

Hi,
I am using client server architecture. I want to stop or start some process which is running on Client Machine.
How can I do this?
Regards,
sjs4u

Server should send messages to client. Client should listen on some port for the messages. Client can interpret the messages and start/stop respective processes. Alternatively, you can use remoting, AFAIK.

hi
how can i load 1,000,000 records to access in the fastest way ?
i'll try:
int End = dsView.Tables["BarcodTbl"].Rows.Count;
int i;
for (i = 0; i < End; i++)
{
Cmd.CommandText = "INSERT INTO BarcodTbl(Code,Barcode,numH) VALUES('" + dsView.Tables["BarcodTbl"].Rows[i][0].ToString() + "','" + dsView.Tables["BarcodTbl"].Rows[i][1].ToString() + "','" + dsView.Tables["BarcodTbl"].Rows[i][2].ToString() + "')";
Cmd.ExecuteNonQuery();
}
but it take over 20 minutes
thanks

I am not sure, but try creating insert statements inside the loop and execute it after the loop finishes. So you are opening only one connection and doing bulk insert.

thanks for the help
can i get any sample code for this ?
