Hi,
There is no problem for printing your ArrayyList values by following.
ArrayList arr = new ArrayList();
arr.Add("Manoj");
arr.Add(4);
arr.Add(4.5);
for (int i = 0; i < arr.Count; i++)
lblResult.Text += arr[i];

you can use ToString for primitive types like int ,double,string,... but in some cases ToString does not return the data we expect (like classes we define by our self) so in those cases you can override the ToString() method.
foreach(object obj in arr)
Console.WriteLine(obj.ToString());
hope the post would be useful

In addition to the ToString() method suggested above, you can also use GetType() on any object which returns an object of type Type. This object has all the information you could ever need on what types are inside your arraylist.

I think you should use an object then add it to your arraylist.
such as You can create an object:
myObject obj =new myObject();
obj.Title="Manoj";
obj.Age=4;
obj.Weight=4.5;
//Add to arraylist
ArrayList arr = new ArrayList();
arr.Add(obj);
//Get from arraylist
for(int i = 0; i < arr.Count; i++)
{
myObject obj = arr[i] as myObject;
Console.Write(obj.Title);
....
}
Hope that help you

Hi,
I need to add some custom tweaks to the regular windows radio button and check box. Basically, i need to tamper with the colours throughout the different events (roll over, disabled,selected...) and cater for the size of the control as well as the distance between the control and its text. I am inheriting my control from the usual System.Windows.Forms.RadioButtton/CheckBox. Can you please give me a tutorial or example that i can follow to achieve this?
Thanks beforehand.
Yours truly,
Krugger

You should write your own controls which inherit from the controls you mentioned and extend their functionality. Perhaps you will need to override OnPaint event

Yes, this is indeed what i need to do. The thing is that i am totally new to Windows controls and do not know how to work this around. Can you plz give me a tutorial or an example i can follow?
Thanks

Hey guys (and girls :->),
My project contains a few win-forms having the FormBorder property set to None. I created a title bar using a Panel containing a few buttons and a label for the window title. When such a form is shown using the ShowDialog method, the window will obviously not blink when the user tries to click outside the dialog window, what 'normal' win-forms including a title-bar do. Now I know there's a possibility to catch such an event using Windows Messages or something anyway... I'm not familiar with Windows Messages. Anyone with usefull hints to get me started??

I am trying to Insert Foreach statement
OleDbadpSource.Fill(dsSource, "Contacts");
string CNN = "id";
foreach (DataRow row in dsSource.Tables["Contacts$"].Rows)
{
OleDbcmdSource.CommandText = "INSERT INTO Address";
Items.Add(row["id"]); //I get an error "No overload for method 'Add' takes '1' arguments"
}
|
|
|
|
|
It means the Add method does not contain an Add() method which allows 1 argument.
What is the type of Items, I cannot find a declaration in your code... Maybe you need to add a few arguments in order to get it working...

Thanks for your prompt reply. I debugged that problem. Now the code works. However, the goal to create a foreach statement was to insert data from the dataset to the table in the SQL Server. Which has not yet taken place.
If you or anybody can help me with that. It will be very much appreciated.

Erhm, that's quite something your asking us. There are loads of ways to insert data into a database from any application. The first huge question is your application structure. If you use a neat n-tier app, your database are coded in a seperate project. However to get you going we'll implement the quickest way to insert data in your database, but keep in mind, though the code works, it's might not be a 'best practice' way to implement the functionality.
To implement a quick way to insert data into your database, create a SQL Insert statement. Therefore you need a stringbuilder which is the quickest for string manipulation.
StringBuilder sbInsert = new StringBuilder();
sbInsert.Append("INSERT INTO ");
sbInsert.Append("DatabaseTableName (");
sbInsert.Append("field, field, field, field"); // <-- Those fields are your database table column names
sbInsert.Append(") VALUES (");
sbInsert.Append("'Value 1',"); // <-- This the value in your database for the first field
sbInsert.Append("'Value 2',"); // <-- This the value in your database for the second field
sbInsert.Append("'Value 3',"); // <-- This the value in your database for the third field
sbInsert.Append("'Value 4'"); // <-- This the value in your database for the fourth field
sbInsert.Append(")");
Now you have the SQL statement, you'll only need to execute that query in your SQL Server. Therefore you'll need a SqlCommand object and a SqlConnection object.
SqlConnection sConn = null;
SqlCommand sComm = null;
try
{
using (sConn = new SqlConnection(ConnectionString[^]))
{
sComm = new SqlCommand(sbInsert.ToString(), sConn);
sConn.Open();
sComm.ExecuteNonQuery();
sConn.Close();
}
}
Catch (Exception ex)
{
MessageBox.Show(ex);
}

Who said anything about Excel? What does excel have to do with it?

Dear All,
Can we filter out the input char other than hexadecimal digits (0-9,A-F) by just setting the Mask string? If it's possible, please tell me how to do it. Many thanks in advance.

I am trying to draw a set of lines within my application window that would show up as an overlay over the existing GUI controls (buttons with images on them)
I can draw the lines in the Form's on paint method, but the buttons are occluding them... is there a way to draw the lines after the buttons have been drawn so that the lines are not occluded?
I thought about using a transparent form that would sit on top of the other form and draw to that.. but I think that will stop me from being able to interact with the buttons..
does anyone know how to draw overlay stuff over controls?
I hope the answer is not to override the buttons on paint...as putting the code there just doesnt seem right.. the overlay is not part of the button objects..
Clear as mud, right?

Whatever else you do, if the button is invalidated, it will repaint itself. You could try using the CreateGraphics method to draw 'over' the buttons, and see if that works, but that definately gets voided when the control is invalidated, I'm just wondering if the main form gets the last say in that event cycle, so it's paint event might draw it again for you.
I'd have though you need to override the paint on the button.

I think the button has the last word there... as when I draw it in an overridden OnPaint method for the form.. the buttons occlude the lines.
I have not looked to see if the buttons are being invalidated unnecessarily. I will check that.
