How about using delegates to get the same result ? is it a good practice ?

A "using"-block will Dispose and Close the form automatically after code block has finished!
So you don't have to worry for that.

It depends of the problem and the way something has to be solfed.
In this case it would be neccesary if the programmer says, that ShowDialog should not be used (maybe because of aditional parallel interaction with an other form).
Than you would have to use Show(), and Form provides the delegates for that (Close and Closing)

All the best,

Martin

The using statement here means that I don't have to remember to call the Dispose() method on the form. Another way to do this would be:

OptionsDialog dlg = new OptionsDialog()
try
{
  if (dlg.ShowDialog() == DialogResult.OK)
  {
    ReloadData();
  }
}
finally
{
  dlg.Dispose();
}

The C# team provided the using command as a shortcut so that any type that implemented IDisposable could be automatically disposed. This feature was added to VB.NET in .NET2.

Using delegates is also a good way to do this, especially if you don't want to go the ShowDialog route. Suppose that you have a modeless dialog, delegates are a very good way to pass the information back.

Open Outlook window using C#

Hi There,

I have to open Outlook window, rather specifically some particular window with in outlook using C#. For example, if a user of my application has to add a new task in the tasks list, or setup a new appointment, I want to allow my users to click on a button on Windows Form and access that particular window i.e. Add New Task Window, Add New Appointment Window etc.

I can do this using Outlook Object Library as well, but in my particular case I have to do this using the actual outlook windows. Well, if I'll be able to do that first, then i'll definitly show a list of the items in my windows form and then let the user click on a particular item and then edit in some outlook editor window.

Any help on this would be really appreciated.

Best Regards,
Shahzad

Thanks very much, Amjath, for the reply.

But, infact, I was looking something to open a specific window of the Outlook. As we can open Outlook itself by using Process class in the Diagnostics namespace. It just opens the main Outlook window, but I was looking for something which can directly open a particular window like Add New Task, Or if I select a particular task from a list it can open the details in the task editor window of the outlook.

The articles you have mentioned can help me do the stuff by coding, but I don't wanna code, I just wanna go to the specific window.

hai all ,
in database i used only one database for empid (int),username(varchar),password(varchar),status(int),usertype(varchar)
what ever i will assign that values are not inserted into database
iam getting value in text but iam not getting in query.
please see my code
<pre>
Label1 .Text =""; //for displaying in design phase
Label2 .Text ="String.Empty;";
Label3 .Text ="String.Empty";
Label4 .Text ="";
Label5 .Text ="String.Empty";
TextBox1 .Text ="empid"; //for entering
TextBox2 .Text ="username";
TextBox3 .Text ="password";
DropDownList1.DataValueField =""; //status 1 and 2
DropDownList2 .DataValueField ="usertype"; //for normal user and admin
SqlConnection con=new SqlConnection ("uid=sa;password=sa123;database=usermanagement;server=c113");
SqlCommand cmd=new SqlCommand ("insert into tbl_user_management (empid,username,password,status,usertype) values('"+ TextBox1.Text +"','"+ TextBox2.Text +"','"+ TextBox3.Text +"','"+ DropDownList1 .DataValueField +"','"+ DropDownList2 .DataValueField +"')",con);

Assign this to a string variable and print that string variable before you execute. Paste the query in query analyzer and you will get the problem. Warning, Using this method you are too close to SQL Injection Attacks. Better read Colin Angus Mckay's SQL Injection Attacks[^] article and change your method.

Try not to do any hardcode..use stored procedure using parameter to avoid SQLInjection..i think u got an error in that code because the empid type is in integer but u inserted a string value to it ( TextBox1 .Text ="empid"; )..try to convert TextBox1.Text to integer format and make sure TextBoxt1.text is a numeric and do this on your SQLcommand(...values('"+Convert.ToInt32(TextBox1.Text) +"',etc...)

Using IP you can send data over network

First you need to write a server application that can connect clients. Server should be multithreaded to accept multiple clients. You can use TCP connection. When one client is sending request to chat with another client, you need to establish a dedicated connection between those two machines and communicate each other.

Good afternoon,
I have a question that need your help
When I summarized the monthly purchase orders(PO), I got my result effectively. But, when I show the names of selected POs in Page header, first I use Crosstab, it works well. Then, I realize that the crosstab will be limited when I provide more than 20 POs. I image about a string instead of Crosstab
My problem is that if I combine the names of POs into a string and assign the string to X2 field. How should I do ?
EX: The list PO can be shown PO1,PO2,PO3,PO4,..
I use Crystal Report in VS C# 2005
Sorry about my English.
I will appreciate your help ! If I misunderstand problem, please kindly explain me well.

It seem to be a solution or an answer.
