That's OK then - now, lets make sure that the OP knows not to do this.

Which is actually a bad one, cause it would make the beginners think, that they would not need an instance of the form (which is per default named "Form2" as class name) to call ShowDialog.
And then will ask 10 min. later why they get a compile error.

try use Form2.ShowDialog()
then you'll not have to set your first form to show after second form is closed

As Martin stated, you should use the ShowDialog method. Then, depending on the DialogResult from the form, you would reload the data (as it doesn't make sense to reload the data if you haven't actually done the save).
Suppose that you have a form called OptionsDialog which you are going to use to add some options into a program and that the details will be saved to the database when the user clicks OK. In this form, set the DialogResult of the OK button to OK.
In your parent form, you would call it with something like this:
private void AddOptions()
{
using (OptionsDialog dlg = new OptionsDialog())
{
if (dlg.ShowDialog(this) == DialogResult.OK)
{
ReloadOptions();
}
}
}I hope that this helps.

Good. My 5. But please make me clear on this
Pete O`Hanlon wrote: using (OptionsDialog dlg = new OptionsDialog())
What is this statement ?
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.

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.
Regards,
Shahzad

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.
