Re: Moving list view items up or down. [modified] - C# Discussion Boards

15-Apr-07 2:24

This is probably very simple but im having trouble getting my head around it.

Ive tried making a temporary list view item which stores the selected list view item,
Then move the selected list view item + 1 up one,
Then the selected list view item + 1 = the temporary,
But i keep getting errors.

Can anyone help me?

Here is my code, im not sure if im even tackling this problem correctly.

<br />
        private void listView1_KeyDown(object sender, KeyEventArgs e)<br />
        {<br />
            if (e.KeyValue == 40)<br />
            {<br />
                ListViewItem temp = new ListViewItem();<br />
                ListViewItem temp2 = new ListViewItem();<br />
                for (int i = 0; i < listView1.SelectedIndices.Count; i++)<br />
                {<br />
                    if(listView1.SelectedItems[i].Index + 1 <= listView1.Items.Count)<br />
                    {<br />
                        //store next item in list<br />
                        temp = listView1.Items[listView1.SelectedItems[i].Index + 1];<br />
                        //store currently selected item<br />
                        temp2 = listView1.Items[listView1.SelectedItems[i].Index];<br />
<br />
                        //swap positions<br />
                        listView1.Items[listView1.SelectedItems[i].Index + 1] = temp2;<br />
                        listView1.Items[listView1.SelectedItems[i].Index] = temp;<br />
                    }<br />
                }<br />
            }<br />
        }<br />

Hi,

there is a bug: if the last listview item is selected (the one with index=count-1),
then temp will refer to the one with index=count, which exceeds the array.

there probably is a second bug: if items 2 and 3 are selected, then maybe
first 2 and 3 get swapped, then 3 and 4 get swapped, which might not be what
was intended.

index       0 1 2 3 4 5
So original A B C D E F
becomes     A B D C E F
then        A B D E C F

Also I am not sure the items in SelectedItems are in numerical
order, in selection order, or random order.

Furthermore, there is no need to create new ListViewItems (temp, temp2).

Hope this helps

Smile | :)

How c# app connect to sql server on another pc in local network?

16-Apr-07 3:08

Since this is not a question, I will only give a piece of advice:

- try to formulate a good, detailed and complete description of what you
want to achieve before you start implementing something
(e.g. what is swapping meant to do when three things are selected ?)
- then implement, test and debug it
- if stuck in a very specific thing, read the documentation, search Google or
codeproject, possibly launch a question here
- if stuck in general, publish all the above plus detailed description of the
behavior you observed and what it is you dont like about it.

I use below conection string, but there's appear error in remote connection.
On same pc connection is OK.

mConnection = new SqlConnection(@"data source=servername\sqlexpress;" +
"database=databasename;" +
"UID=user;PWD=pass;");

Error mesage is:

An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)

Server Authentication is SQL Server and Windows Authentication mode.
Allow remote connections to this server is set.

What may cause this mistake?

Thanks.

Hi,

Your problem is that SQLExpress server by default has Named Pipes and TCP/IP protocol disabled. In order to connect to SQLExpress on different networked PC you should enable at least one of this protocols and restart your SQLExpress service under:

SQL Server Configuration Manager :: ... Network Configuration :: Protocols for ... :: Named Pipes and (or) TCP/IP.

Also it could be (but not necessary) required to setup client protocols on client PC.
Some other settings may be required on your firewalls and ...

After that, it should works.

That would explain it. That method is only available in framwork 2.
