Hi,
when multiple monitors all contribute to a single desktop, they have their own position in the coordinate system of the desktop; the first monitor typically has its top left corner at (0,0); the others can be anywhere (you can drag them in the Display Properties dialog).
Have a look at the Screen class to determine the exact coordinates.
Then launch your app(s) and move their main window; the Process class gives you the MainWindowHandle; you then can send a move message (using P/Invoke) with the appropriate parameters.

Hi Luc,
Thank you for your answer.
This can be a solution, If I use pptview.exe to show the ppt as a process than I can do this. I hope I can tun multiply pptview.exe.
Let's say the display is done. But how can I redirect the sound output of a Process to a specified sound device (ppt-s can contain sounds usually played on the primary sound device). This is not good because I would like to show ppt-s on different screens with its own speakers.
Can I do anything with the sound?
I know this is a hard question but four PC cost much more money than one.

Hi all,
I'm doing a program that saves customer details to the database and I'm using NHibernate. I'm very new in it and I'm getting help from the net. I have a problem compiling the mapping file, I get the following error:
"Could not compile the mapping document: Customer.hbm.xml"
I don't have an idea of what I did wrong. Please, if you know what I missed or did wrong, I'd really appreciate your help/advice. Thanks.
Here is my class:
using System;
using System.Collections.Generic;
using System.Text;
using NHibernate;
using NHibernate.Cfg;
namespace NHibernate_Demo
{
class Program
{
static void Main(string[] args)
{
// Loads the NHibernate Types to prepare for Serialization
Configuration cfg = new Configuration();
cfg.Configure();
//cfg.AddAssembly(typeof(NHibernate_Demo.Customer).Assembly);
//cfg.AddClass(typeof(Customer));
cfg.AddFile("Customer.hbm.xml");
//Opens a session to NHiberbate to allow us to work with objects
ISessionFactory sessionsF = cfg.BuildSessionFactory();
//let ISessiionFactory open connection
ISession sessionS = sessionsF.OpenSession();
ITransaction transaction = sessionS.BeginTransaction();
{
Customer customer = (Customer)
sessionS.Load(typeof(Customer), "ALFKI");
// Show the Contact Name of the Customer
//MessageBox.Show(customer.ContactName);
sessionS.Close();
}
}
}
}
I get an error at this line:
cfg.AddFile("Customer.hbm.xml");
Thanks.

Hi,
Look at Splicer[^]. I am not sure if it lets you watermark videos with images, but it does allow you to watermark with text.

I an having some trouble with removing duplicate entries from an xml file.
I am using mostly Linq to XML and C# to build the list.So I would like a Linq to Xml aproach further too.
Example(before):
<SYNSET>
<ID>new_id</ID>
<SYNONYM>
<LITERAL>word1<SENSE>II.♦</SENSE></LITERAL>
</SYNONYM>
<DEF> definition1 </DEF>
</SYNSET>
<SYNSET>
<ID>new_id</ID>
<SYNONYM>
<LITERAL>word2<SENSE>I</SENSE></LITERAL>
</SYNONYM>
<DEF> definition2 </DEF>
</SYNSET>
<SYNSET>
<ID>new_id</ID>
<SYNONYM>
<LITERAL>word1<SENSE>II.♦</SENSE></LITERAL>
</SYNONYM>
<DEF> definition1 </DEF>
</SYNSET>
After it should be:
<SYNSET>
<ID>new_id</ID>
<SYNONYM>
<LITERAL>word1<SENSE>II.♦</SENSE></LITERAL>
</SYNONYM>
<DEF> definition1 </DEF>
</SYNSET>
<SYNSET>
<ID>new_id</ID>
<SYNONYM>
<LITERAL>word2<SENSE>I</SENSE></LITERAL>
</SYNONYM>
<DEF> definition2 </DEF>
</SYNSET>
The xml database should have around 100k entries like this, so I need a fast method to remove duplicates. Thanks in advance

Probably be best to use a hash table...
have a look at the Dictionary[^] class.
Then read you xml file.
Loop all the entries.
Build a string[^] of all entry values.
Create a hash[^] of that string.
Check if the hash value is in the dictionary (with its Contains function)
If its not there then add it to the dictionary then export the entry row to the new xml file.
End of loop.
If you skip the hash step and simply add the built string then it will use more memory but the process speed may be faster. You will have to test and decide yourself.

I dont think it will really work. As I said to you the xml database has around 100.000 entries. What I wanna do is check if an entry appears 2 times in that database and remove the duplicates. I read the dictionary class a bit, not really what I am looking for.
|
|
|
|
|
Well I have used the same process to remove duplicate lines from a text file (100MB+) so I know it will work.
How do you expect to check if a line is a duplicate? you have to check each line against all other lines in the file right?
you could skip the dictionary part and check all lines in the new file each time you read one in from the original file. That would certainly improve memory consumption but your processing time would greatly be reduced.

|
|
so the method works for not adding duplicates in a file? And how do you remove it the duplicate in the file.
|
|
|
|
|
Yeah, but that is how you will need to do it. You cant just duplicates from a file, unfortunately there is not a function such as File.RemoveDuplicates();
Of course you could read a whole xml file into a datatable and then remove duplicates and re-write it back to the file but you don't want to have to load all the data into memory at once.
So the best way is to create a reader for you xml file. Then read it one entry at the time and concatenate all the values into one string.
Then you either use some sort of collection to store unique entries which you can use to check for duplicates. Or you can write straight to a new file and just check that file for duplicates each time. if a duplicate is found in which ever method you choose then you simply ignore that entry and read the next entry. Then you have either a file will unique entries, or you have a collection of unique entries which you can then write to a new file.
Fairly straight forward concept really.

that worked out good for me..thank you...
The code:<pre>
XElement duplicate = XElement.Load("wnrom2.xml");
StringBuilder build = new StringBuilder();
Dictionary<string, string> dict = new Dictionary<string, string>();
foreach (XElement dup in duplicate.Descendants("SYNSET"))
{
build.Append(dup.ToString());
}
dict.Add("a", build.ToString());
if (dict.ContainsValue(synsets.Descendants("SYNSET").Last().ToString()) == false)
{
synsets.Save("wnrom.xml");
synsets.Save("wnrom2.xml");
}
</pre>

Hi,
I have a list view with 5 columns and 4 items in that listView.
When i click on a row ( item) of that listViewi want the whole row to be highlighted blue , and if i select another row, what that it to be selected as well.
So basically i want it to look like the whole row is selected not just the first column item.
here is what i tried :
private void listView1_Click(object sender, EventArgs e)<br />
{<br />
for (int i = 0; i < listView1.Items.Count; i++)<br />
{<br />
if (listView1.Items[i].Selected == true)<br />
{<br />
listView1.Items[i].BackColor = Color.Blue;<br />
}<br />
}<br />
}
BUT this works after I change the selection of the row! for example i select row 1 , and when i select row 2 , then row 1 is highlited . Why guys?
Any suggestions please?
Regards,
Alex

That's unnecessary, use listView1.Items.SelectedIndex.
Then to apply the color change use listView1.Refresh();.
