Hi Guys and Gals.
I have never in my life before worked with Windows Services. I have an urgent project where I must create a Windows Service to Export data from a DB to another DB every 5 min. If anyone could give me guidance on this it will be greatly appreciated. I just dont know where to start or go about doing this.
Please help.
Regards,
Elizma

Hi Elizma,
I think first you need to make some test application in window services with timer. Two many article posted on web you can go through via google or you can find below link:

After that if you have any problem then you can discuss with us.

Hi guys.
I am struggling in one point whether the values in an xml document can be converted in to a Generic List<t>. ie. when i will read an xml document, it will return a List<t>.I am converting the xml to a Generic List<t> because i have go through 3 tier architecture.
If possible please give me some Urls(sites) where i can get some idea.

Why do you need a list for 3 tier architecture? This is by no means a requirement of good n-tier design.

Hello everyone,
With a C# made software, I create an Excel file with many sheets. Everything
goes well until I tried to remove PageBreaks.
I can add them but I can't delete them so I still have the automatic one
appearing there ...
I tried a lot of things such as:
Range AutoVPageBreaks=ExcelWorksheet1.VPagesBreaks[1].Location;<br />
AutoVPageBreaks.PageBreaks=XlPageBreaks.XlPageBreakNone;
or
VPageBreak VPB1= ExcelWorksheet1.VPagesBreaks[1];<br />
VPB1.Delete();
--> This one raised an error
I also tried to add before ResetPageBreaks() or DisplayPageBreaks=false but
nothing worked ... I still have the automatic pagebreaks ...
Does someone know howw to remove those pagebreaks? Do I need to set the
sheet to printpreview? If so, how? (I tried but that raised an error)
I hope you can help me.
Thank you.

My ListBox Contents are in the form
index. itemName
1. Jack
2. Jane
3. Joe
4. Bill
5. Tim
6. Sid
On removing say Jane I need to get the index of others in proper numerical order. Now ListBox Control only allows me access to the currently selectedItem via its selectedItem property but I need access to all the Items so that I can change them...
Any Advice...
Thanks
Please excuse if this is a very basic question. I'm pretty new to C#.
After Removal the above should become
1. Jack
2. Joe
3. Bill
4. tim
5. Sid

If you iterate through the Items collection, you get the zero based index of the item.

Yes I can do that as
IEnumerator enm = this.list.Items.GetEnumerator();
int i = 0;
//Get to The Desired Location
for(i = 0; i < index; i ++ )
{
enm.MoveNext();
}
//Here I can Get Individual Items
for(i = index; i < list.Items.Count; i ++)
{
String entry = enm.Current.ToString();
String newData = doSomething(entry);
// Now Here I Need to Set the Changed Data to ith Position in the List
// cannot Do enm.Current = newData as Current is a readonly Property of IEnumerator
}
Any More Advice...

I'm sorry, but I'm not sure what you are trying to achieve here. This has gone beyond the scope of your original query. Perhaps you could elaborate a bit.

Sorry about confusing anybody. Here is what I want
My Playlist is displayed in ListBox named list
with contents
1. SongABc
2. Song Dev
3. Vid34
4. Clip5
5. ABC and so on
I need to delete an item from that
for that I'm doing
this.list.Items.RemoveAt(index);
Now I need to update the IndexNumber of each entry in the Playlist so that after deleting "Vid34"
My list shows
1. SongABc
2. Song Dev
3. Clip5
4. ABC and so on
I can READ ALL items of list as
IEnumerator enm = this.list.Items.GetEnumerator();
int i = 0;
for(i = 0; i < index; i ++ )
enm.MoveNext();
//Now I'm at the place where I Delete the Entry
//all the Following Items need to update their Numerical Index Decremented by one
for(i = index; i < list.Items.Count; i ++)
{
String entry = enm.Current.ToString();
String newVal = getNewVal(entry); // Strip Index Value so that "4. Clip5 becomes just Clip5"
//Here I need to set the Current Entry with new Val something like
this.list.itemAt(i) = newVal; // But no such method exists
neither can I do
enm.Current = newVal; // Because it is a readonly property
}
I can clear my playlist and readd everything but that would be waste of resources

Aah. I see what you're getting at. Well, the simple way to do it would be to use list.Items[i] = newVal; in the loop. You can simplify the logic quite a lot:
for (int i = 0; i < list.Items.Count; i++)
{
string entry = enm.Current.ToString();
list.Items[i] = getNewVal(entry);
}

Nope, not at all. Don't put yourself down - at least you had a go before posting. There are too many who would just have asked without trying anything themself.

Use the Items collection of your ListBox to modify the contents of the list.

Hi,
there is a different and better way to achieve a numbered list: ListBox (and ComboBox) support
"OwnerDraw" mode, which means you paint the items yourself in any way you like, instead
of their string value being shown as is. So what you could do is add a DrawItem handler
that does a Graphics.DrawString(itemIndex.ToString()+". "+item.ToString());
Doing this will automatically show the text with its number, whatever happens to the list.
You would have to get the itemIndex from DrawItemEventArgs.Index, and item from
myListBox.Items[itemIndex].

am trying to develop one aplication to read a particular node in an xml file. but somewhere i goes wrong and not working.......
plz help me to find out the error.....
In the following xml file i want to find out the last name.
This is the xml
<?xml version="1.0" encoding="UTF-8" ?>
<family>
<name gender="male">
<firstname>Tom</firstname>
<lastname>Smith</lastname>
</name>
</family>
and the code is --------
FileStream fs = new FileStream("D:\\Myfolder\\gender.xml", FileMode.Open, FileAccess.Read, FileShare.ReadWrite);
xmldoc.Load(fs);
XmlNodeList xmlnode = xmldoc.GetElementsByTagName("name");
for (int a = 0; a < xmlnode.Count; a++)
{
if (xmlnode[a].Attributes[0].Value == "gender")
// match your attributes
{ //codes
lblcnt.Text=a.ToString();
String firstNameValue = reader.ReadElementString("gender");
Lblmsg.Text=" FirstName: "+firstNameValue;
}
I tried this one also=======
XmlTextReader reader = new XmlTextReader ("D:\\Myfolder\\gender.xml");
XmlDocument xmldoc = new XmlDocument();
XmlTextReader reader = new XmlTextReader ("C:\\gender.xml");
try
{
while (!reader.EOF)
{
reader.Read();
if(reader.IsStartElement() )
{
reader.Read();
xmldoc.SelectSingleNode("family/name/firstname");
XmlNode xmlnode1=xmldoc.GetElementsByTagName("firstname");
String firstNameValue = reader.ReadElementString("firstname");
xmldoc.SelectSingleNode("lastname");
String lastNameValue = reader.ReadElementString("lastname");
Lblmsg.Text=" FirstName: "+firstNameValue + " LastName: " + lastNameValue;
}
}
reader.Close();
}
catch (Exception err )
{
Lblmsg.Text="Error: " + err.ToString();
}

This is a disaster

This would work if
a - you loaded your xml into xmldoc, and
b - you grabbed the return value from the call

I think this will help U
DataSet ds = new DataSet();
ds.ReadXml(Server.MapPath("gender.xml"));
DataTable dt = ds.Tables["family"];
DataRow dr;
for (int i = 0; dt.Rows.Count > i; i++)
{
dr = dt.Rows[i];
String firstNameValue = dr["firstname"].ToString();
String lastNameValue =dr["lastname"].ToString();
Lblmsg.Text=" FirstName: "+firstNameValue + " LastName: " + lastNameValue;
}
