I am new to threading and was wondering how to tell if you have "memory leaks"?

You will need to analyse your code. Check if the unreferenced objects are disposed or not.

I have made a User Control in C#. It has two buttons, Submit and Cancel. The Submit button event is handled in the Control's code itself. I want to handle that Cancel buttons event so that it closes the form on which it is placed. And I want to make that Submit button the AcceptButton and Cancel as the CancelButton. Please tell me in what way I can achieve this.
Always Keep Smiling.

On CancelButton's clientclick event write a client side (javascript) function to close the window.
e.g;
window.opener=null;window.close();
Hope this helps

Its a window application for which I was talking about... I think this solution will work for the Web Applications. I dont have that knowledge about web applications. Anyway thanks for trying.

Since the usercontrol does not have a accept button property, you will need to expose the submit button and then set the AcceptButton property. Same will work with the cancel button as well.

Thanks for the Answer. Can you tell me how to expose the button ? Do you mean that I should add the button on the control at runtime ?
Always Keep Smiling.

If you need to be able to set Accept and Cancel you can't do it with the designer.
In the user control create readonly properties for Accept and Cancel buttons
[Browsable(false),
DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)]
public IButtonControl AcceptButton
{
get { return button1; }
}
[Browsable(false),
DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)]
public IButtonControl CancelButton
{
get { return button2; }
}then in the host form you can set in code
AcceptButton = userControl11.AcceptButton;
CancelButton = userControl11.CancelButton;
If you want it through the designer then you can only have one button. Just make the user control also derive from IButtonControl and implement it to use the button in question.
DaveBTW, in software, hope and pray is not a viable strategy. (Luc Pattyn)Visual Basic is not used by normal people so we're not covering it here. (Uncyclopedia)

Wow...didn't knew this thing. If had the same issue, I would have exposed the button to the form. This would have made the purpose of having a user control go in vain. It's one thing I learnt today. Thanks.

Thanks a lot for this one...I will surely try this one. And what about the event handler ? Can you help me ?

There's a few ways this can be done. The easiest is just to subscribe in the user control and raise a new event each time.
using System;
using System.ComponentModel;
using System.Windows.Forms;
namespace WindowsFormsApplication1
{
public partial class UserControl1 : UserControl
{
public event EventHandler Button1Clicked;
public event EventHandler Button2Clicked;
public UserControl1()
{
InitializeComponent();
button1.Click += new EventHandler(button1_Click);
button2.Click += new EventHandler(button2_Click);
}
protected virtual void button1_Click(object sender, EventArgs e)
{
EventHandler eh = Button1Clicked;
if (eh != null)
eh(this, e);
}
protected virtual void button2_Click(object sender, EventArgs e)
{
EventHandler eh = Button2Clicked;
if (eh != null)
eh(this, e);
}
[Browsable(false),
DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)]
public IButtonControl AcceptButton
{
get { return button1; }
}
[Browsable(false),
DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)]
public IButtonControl CancelButton
{ get { return button2; }
}
}
}You now have userControl11.Button1Clicked and userControl11.Button2Clicked events available in your host form like any other control's events.

I'm using VS2008 to develop C# applications.
Where can i find all the shortcut key of VS2008?
Perhaps, the experience programmers can share with me the useful shortcut keys or macro which can improve coding productivity.

Hi all
I have 2 tables in the same data set like this:
string sqlCus="select * from Customers";
string sqlOrder="select * from Orders";
SqlDataAdapter daCus=new SqlDataAdapter(sqlCus,conn);
SqlDataAdapter daOrder=new SqlDataAdapter(sqlOrder,conn);
DataSet ds=new DataSet();
daCus.Fill(ds,"Customers");
daOrder.Fill(ds,"Orders");
now I want to get the OrderID column in Orders table and ContactName (CustomerName) in the Customers table according to the CustomerID column in the Orders table then show both column in a DataGridView control, how to do that?
note: not use stored procedure and Linq
|
|

|

You could do one query and join the tables on the query
string sql = "select ContactName, Orders.OrderID from Customers Left Outer Join Order ON CustomerID = Order.CustomerID";
The above should work, you may just have to change the column names to what you want. You could also add an Order by statement in the end of that if you wanted.
This link may help you in the future with joining tables in sql queries.
http://en.wikipedia.org/wiki/Join_(SQL)[^]
hope that helps you.

Thank you for your answer, but what I wanted to know is how to join 2 tables in the same data set using data relation. I do know how to join 2 tables using sql's select command, but this one is not.
Could you please point me out for this?
Thanks

I'm sorry the first answer did not help you, I'm guessing you have a reason to populate two separate datasets and then parse through them to get your info.
You may want to look at this article, it explains how to use select/sort things using your dataset and a datatable.
http://msdn.microsoft.com/en-us/library/system.data.datatable.select.aspx[^]
Also you will most likely have to do a dataset copy then dataset.add to add the columns to the copied dataset in order to get the results you want. Not sure if this is exactly what your looking for but hope this points you in the right direction.
