Hmm.. looks ok to me. Do you databind before you call the Items.Insert method?
Maybe you could post some more code..?

Yes i binding data. My complete function is
private void BindZOne()
{
using (Common ComObj = new Common())
{
DataSet Ds = ComObj.BindZone();
if (Ds.Tables[0].Rows.Count != 0)
{
ddlZone.DataSource = Ds;
ddlZone.DataTextField = Ds.Tables[0].Columns["ZONE"].ToString();
ddlZone.DataValueField = Ds.Tables[0].Columns["ZONE"].ToString();
DataBind();
ddlZone.Items.Insert(0, "SELECT");
} Ds.Dispose();
}
}

It might just be a typo from your part, but unless you have a method called DataBind that takes care of the databinding part for your drop down list, you should probably call the ddlZone.DataBind() method instead..

Take a look at Unbound items in a bound ComboBox[^].
Alternatively in this[^] thread (scroll down to the bottom and look for a reply from 'BOZ') there is a solution that seems to work.

I'm not sure about C#/WinMo but there's a few Android offerings that may be good for research purposes for you. One of the apps hooks into this[^] I believe.

Google around for "Augmented Reality", a few apps already exists, e.g. Wikitude and Layar. Although they're not games, they might prove an interesting read for you.

Hi
I have a SortedDictionary and I need to find the first key match with the character(s) given. For example, if c has been pressed, I need to get the first word in the SortedDictionary that starts with 'c'. Is that possible?
I've read about
SortedDictionary< TKey, TValue> .First Method and
Enumerable.First< TSource> Generic Method (IEnumerable<TSource>, Func<TSource, Boolean>)
in MSDN, but I can't understand it.
|
|
|
|

I believe the second is telling you that you can write a function that takes the tsource and returns a bool to tell you a match, and pass it to the First method.

In IE, when You type some URL in the address bar, corresponding web page will be displayed on screen.
How to catch this web page data on IE, using c#.

If your IE is a browser control inside your app, you can examine the HTML from there. If it's just IE, you may well be screwed.

Hi,
i am also working in the similar type of problem.
using SHDocVw.InternetExplorer, you can get the DOM object.
from that you can get the entire source...
i am just struggling to get the frame element values in Gamail because it uses some strange format. by all means you can just catch the data from the DOM.
Regards

My project is large, so I can't remember when I last made any changes to this particular form, which used to work.
To bind the my datasets to the datagridviews I have:
bsUsers.DataSource = dsUsers;
bsUsers.DataMember = "UserList";
dgvUsers.DataSource = bsUsers;
bsRoles.DataSource = dsRoles;
bsRoles.DataMember = "RolesList";
dgvRoles.DataSource = bsRoles; The grids display the correct data.
At the start of saving changes I have:
Validate();
BindingContext[dsRoles, "RolesList"].EndCurrentEdit();
BindingContext[dsUsers, "UserList"].EndCurrentEdit(); The last line gives the runtime error "Child list for field UserList cannot be created". The previous line (dsRoles) works.
I have copied and pasted "UserList" just to make sure that there are no invisible spelling mistakes.
In the Watch pane I can't find any property for dsUsers where one can check if "UserList" is still correct.

Are you trying to reinitialize your grids bindings few times?

I want to make a C# calendarin which I want to show all the events( plans, appointments, festivals etc) from a database.The application should be a Windows application.
Would you please list me the possible( some easiest) ways of doing that.
1) Is there any to to select a date and write some text in it?
2)If I am making a custom calendar by inheriting the monthCalendar class, what are the extra things I need to do or learn?
3)Is there any way to bind the monthcalendar or a class inherited from monthecalendar class, in which I associate it to a
source and the events goes to their respective dates?
Any help will be highly appreciated.

I'm not sure what this means, but you can display a date with a textbox underneath, quite plainly

This is a terrible idea. The control is bound to cause you more grief than good

Hell no. Of course not. The control doesn't have any sort of idea of binding dates and events, because it does not do that

Hi,

Regards
Sebastian
P.S.: Please don't shout next time...
|

|
|
|
yes i tired this bt it show 12 hour after 12 am show 1 pm bt i want 13:00.
|
|

|

Okay, now I need more information. What are you doing exactly? Could you post a bit of your code?
|
|
|
|
|
this is my coding
InitializeComponent();
{
timer.Tick += new EventHandler(timer1_Tick);
timer.Interval = (1000) * (1);
timer.Enabled = true;
timer.Start();
}
private void timer1_Tick(object sender, EventArgs e)
{
DateTime dt = DateTime.Now;
Time.Text = dt.ToString("hh:mm:ss");
}
|
|
|
|
|
As said before: You have to use ToString("HH:mm:ss"). The format-string is case-sensitive. Uppercase H means 24-hour format.
