I think he meant you have to handle the Closing Event on the form. In the desiner click once on the form. Press F4 (or select the properties tab from the sidebar) then press the events button at the top of the properties side bar. You will see somewhere in the list events Closed and Closing (pay attention to the verb tense).
Closing occurs as the form is in the process of closing at this point you still have time to abort the action. You will find that the event arguments for this event include a property called Cancel, set that to true.
Does this help?

I guess I don't quite understand how arguements work. (thanks for the help by the way!)
|
|
|
|
|

so I have this "private void Form1_Closing(object sender, System.ComponentModel.CancelEventArgs e)".
{
//what goes here to keep it from closing?
//I've tried "Form1_Closing(true)"
//that didn't work
//so what's the correct way of doing this?
}
thanks so much,
Stephen

You don't call this method directly. The event fires and the Framework will call the method. The important thing here is the parameter e, which is of type CancelEventArgs (See MSDN[^] for details. This has a Cancel property, which you can set to true to stop the form from closing.
Your code will look something like:
private void Form1_Closing(object sender, System.ComponentModel.CancelEventArgs e)
{
if (testToSeeIfClosingShouldBeCancelled)
{
e.Cancel = true;
}
}

basically, I have a richTextBox, and I want to be able to highlight anything inside between "<" and ">", with the color blue. And anything between "<" and ">" that is surrounded in quotation marks green. if you could provide any code, that would be very helpful.
thanks a bunch,
Stephen

Well, I couldn't find out how Rich Text is saved but maybe you could do that with some Regexps
(http://msdn.microsoft.com/library/en-us/cpguide/html/cpconRegularExpressionExamples.asp)

orelse u can use text.color option while outputting text onto the textbox between those symbols.

Hello World!
I am stuck with a big algorithmic application I had developed. There is a StackOverflowException is thrown when I try to extend the program a bit more. Is there a way to expand the Stack depth of the system ? Couldn't find any in MSDN...
I am also suspecting that other heavy routines, when return, somehow stack isn't released by them, so when I add after them in a root line, an additonal routine (doing small recursion) - not in parallel, the program falls when the recursion first entered, like if I am dancing on the edge of the stack limit most of the program time.
Another thing. Checked the Stack class. Couldn't quite understand if possible to attach some processes to a new stack handle I create with this class, and with that, to split program to use more than one stack. Is it possible??!
A note: all my routines run inside a timer tick, when in the beginning of each tick, I stop the timer, do all the stuff and start it in the end....
Thanks ahead.

 Hey, thanks for the response.
But I have tested the recursive function, it depth is max. 10 in all cases and I pass 2 integers each time. And important of all, it is running OK when I shut down all nonrecursive heavy routines running before it.
Somehow, there are pending methods left, raising the program proximity to the stack limit. Anyway, do you know how can I raise the stack limit ? Is it possible ?

Hello and merry christmas
I want to convert my localtime (I'm living in Belgium) Format : DD/MM/YYYY HH:MM:SS with time of ntp server (Format : MM/DD/YYYY HH:MM:SS no AM/PM)
Can you help me ?
My best wishes.

I haven't tested this or anything, but I'm pretty sure all you need to do is use the ToString() method. For instance...
DateTime time = DateTime.Now;
string formattedTime = time.ToString("MM/dd/yyyy hh:mm:ss");
For more information, check out MSDN's custom DateTime format strings[^].

Hi,
Is there anyway I can set a timeout for an asynchronous call in remoting. The intention is that if the method takes a long time and it is not worth waiting that long, the execution should proceed. Kind of taking off the blocking aspect of EndInvoke call.

What was wrong with the answer[^] that I gave to you a few days ago? If you didn't understand it then I am more than happy to clarify anything. I did make some assumptions that you knew your way around the SqlConnection and SqlCommand objects well enough to perform a normal query (SELECT, INSERT, DELETE, UPDATE) so maybe that was incorrect.
Do you want to know more?

Use your fmapppas() constructor to call login form. And try to execute your login related logic.That will be a good solution for this.

Hi Thanks for your help but i am not using MDI Application. So please tell me other solution.
Please...

The problem is that the ApplicationContext MainForm of your application is the fmapppas form. That is because you are starting the applicatoin in this form with the code: Application.Run(new fmapppas());
When this form closes, u are exiting the application.
On the other hand, if u hide the fmapppas form, the application will keep on running forever because the user can't close the hidden form and thus finalize the application because there is no GUI available (would have to do it through the taskmanager).
Solutions: You should always use the application's main form as the ApplicationContext mainform: That is, start the app with the mainfm or set it as the ApplicationContext's MainForm if your using a custom application context:
[STAThread]
public static void Main()
{
Application.Run(new mainform())
}
then override the main forms OnLoad method and start the logging form from there:
protected override void OnLoad(EventArgs e)
{
base.OnLoad(e);
fmapppas frm=new frmappas;
frm.ShowDialog(this);
}
If u really dont want to change the structure u have right now, u could probably fix your problem simply overriding the mainfm's OnClosed method and force the hidden form to close also:
protected override OnClosed(EventArgs e)
{
fmapppas.Close();
base.OnClosed(e);
}
