Hi!
You'd have to use the SelectionColor property for that. For example, something like this should work:
richTextBox1.Select(startOfMessage, 0);
richTextBox1.SelectionColor = Color.Red;
richTextBox1.SelectedText = "Message from User 1" + Environment.Newline;
richTextBox1.SelectionColor = Color.Blue;
richTextBox1.SelectedText = "Second message from User 2" + Environment.Newline;

How is it possible to maintain and share hashtables inside a webservice?
For example: a webservice adds data to hashtables. The hashtable data has to be shared between each application that calls the webservice.
p.s. I am trying to avoid creating files for each hashtable.
Thanks

i think by declaring ur hashtable as static will solve ur problem.

It does NOT because I am using static at present.
Thanks

A web service is (typically) stateless. This is the behaviour that you are seeing.

hi all,
i am filling the data into CheckedListBox in PageLoadEvent,
and here i wanted to manipulate the selected/deselected values in itemCheckEvent BUT I AM Failing to do so, its givining Null Ref exception,,
see here, i am filling the checkedlistbox in the pageloadEvent,
and wat i need to do is, i need select/deselect the values of checkboxes
if i select i need to add to backend file,
if i de-select i need to remove from backend file.
for that i have choosen item_click event, but its giving null ref exception in the pageload itself coz i am adding values in pageload and also using the below code to catch select&deselect
private void checkedListBox1_ItemCheck(object sender, ItemCheckEventArgs e)
{
if (e.NewValue == CheckState.Unchecked)
{
lstChcked.Items.Remove(chklstMultipleMdfyTbl.SelectedItem.ToString());
}
else if (e.NewValue == CheckState.Checked)
{
lstChcked.Items.Add(chklstMultipleMdfyTbl.SelectedItem.ToString());
}
}
reply,,thnx in advance

I already told you that you should not register your event handler to the ItemCheck event until you loaded your data into the CheckedListBox i.e. register it in the Page_Load event handler after you're done with loading the data. I also told you how to register (by hand) and where you should find the original event registration (most probably added by the designer). What more do you need?

i am very sorry to bother u Again and Again,
but finally once plz look at my code once, so that i feel u can understand my problem.
i'm filling my checkelist box in pageload using the below code,,
private void frmCustomizeParams_Load(object sender, EventArgs e)
{
blnItemChk = true;
TestingBoard.XMLTasks GetLasersProperties = new TestingBoard.XMLTasks();
string[] LaserChecking = new string[xmltask.GetLaserPropCount("tabular", "property")];
bool[] chkedList = new bool[xmltask.GetLaserPropCount("tabular", "property")];
LaserChecking = GetLasersProperties.GetLaserProp("tabular", "property");
chkedList = GetAllLaserPropchk("tabular", "property");
for (int i = 0; i < LaserChecking.Length; i++)
{
chklstMultipleMdfyTbl.Items.Add(LaserChecking[i], chkedList[i]);
if (chkedList[i])
{
lstChcked.Items.Add(LaserChecking[i]);
}
}
}
}
Here is the ItemCheck Event Handler to Handle the Check/Unchecked Events of itemCheck Event Hanlder, here i am taking a listbox and want to fill selected/deselected values.
here is my Item_Check Event of CheckedListBox
private void checkedListBox1_ItemCheck(object sender, ItemCheckEventArgs e)
{
if (!blnItemChk)
{
}
else
{
if (e.NewValue == CheckState.Unchecked)
{
lstChcked.Items.Remove(chklstMultipleMdfyTbl.SelectedItem.ToString());
}
else if (e.NewValue == CheckState.Checked)
{
lstChcked.Items.Add(chklstMultipleMdfyTbl.SelectedItem.ToString());
}
}
}
Compiler is giving the below exception
{"Object reference not set to an instance of an object."}
Thnx alot for ur kind response till now,
very very sorry to bother u bye byes

I've taken a look at your code and I fully understand your problem. Maybe you should take a closer look at my answers and try to realize them.

Change your Class1 to:
public class Class1
{
public int valInt;
public string valStr = string.Empty;
}
|
|
|
|
|
Yes,
the solution for this simple example is that but..... if i can't modify the class ...
|
|
|
|

Then XML serialization is not the way to go since it serializes only the public fields and properties.

One thing you must understand is that the Xml generated by the serializer in question must be able to distinguish between null and a blank string. As your string type is nullable (where the int is not) the Xml generated produces no node when it is null and an empty node when there is a blank string.
So, basically what you want is neither practical nor possible unless you can change the class definition to set the string to String.Empty
The only other option is to write your own Xml Serializer and loose the ability to distinguish between a blank string and a null string.

3/2/2007
2/3/2007
8/3/2007
2/4/2007
2/5/2007
5/5/2007
Now want to access minimum date from it :
SELECT MIN(accessdate)
FROM tblsummary
i shud get : 5/2/2007(as minimum),
But i m getting : 2/3/2007(as it is just comparing 2<5 ie date, but not month which is 2<3)
Same is happening for max(accessdate) too.
How can i rectify it,it wud b pleasure if some1 can help.
Thank You in adv.

SELECT MIN(CONVERT(varchar, DateCreated, 111)) FROM tblsummary
|
|
|
|
|
SELECT MIN(CONVERT(varchar, DateCreated, 111)) FROM tblsummary
error in query analyzer:
Invalid Columnname 'DateCreated'.
'accessdate' column in 'tblsummary'table has 'datetime' datatype.
Did u understand my problem in last post?
My query is not checking month.
Does 'datetime' datatype takes data in database as 'mm/dd/yyyy'?
I inserted data as 'dd/mm/yyyy'.

Please don't use txtspk. This is a forum, not a text message.
Store the dates as dates, not as text. Otherwise you have to convert each value to date in the query to get the aggregate to compare them as dates.

date is stored in database in only one way. u have to fatch date as u want in any format.
y'r prob solved with above posted ans. query .

datetime datatype stores data in mm/dd/yyyy format.
now its working.
thank you.
