I'm not very familiar with asynchronous execution but I think the following should work:
When beginning the asynchronous call pass the actual instance of TestForm as state object and retrieve it in the callback by using the IAsyncResult.AsyncState property.

system notification in Window

Hi all,

I am writing a program that can notify users of certain event
by showing up a pop up window of the notifying message on the
desktop. The notification can be set to be triggered at a preset time.
The notification message can be triggered even that the program is not running, once it is set to be triggered at certain time by the program and then the program is shutdown. Is it possible ?

Thanks
Patrick

There are obviously 2 ways to do it (or there are 2 I know of).

You could use the Windows-Scheduler and have it start a program at a certain time. That program could then "notify" the user.

Or you could create a little "Taskicon"-Application which would be launched by the program and do your notification.

Basically, that is the way Real (RealScheduler/RealPlayer), ICQ and others do it: they have a small app running, which reacts to certain events.

By your requirements, there's nothing special here. All you do is drag the boxes you want onto the form and arrange them how you want. All the properties and methods of the boxes are available to any code behind any of the controls on the form after that.

int casting does not behave with Math.Round with NaN?

Felix Cho2-Dec-04 19:24

Found a weird bug in an app that we are writing, and I narrowed down to this special case:

<br />
	double a = double.NaN;<br />
	Console.WriteLine("a = {0}", a);<br />
	Console.WriteLine("(int)a = {0}", (int)a);<br />
	Console.WriteLine("Math.Round(a) = {0}", Math.Round(a));<br />
	Console.WriteLine("(int)Math.Round(a) = {0}", (int)Math.Round(a));<br />

We just moved to 1.1 so this appears to be a 1.1 issue.

For debug build, the output is:

<br />
a = NaN<br />
(int)a = 0<br />
Math.Round(a) = NaN<br />
(int)Math.Round(a) = 0<br />

For release build, the output is:

<br />
a = NaN<br />
(int)a = 0<br />
Math.Round(a) = NaN<br />
(int)Math.Round(a) = -2147483648<br />

It seemed for some reason Release does not behave the same and that was causing my problem. Granted I shouldn't depend on the cast to be 0 because it is NaN (should never depend on undefined behaviour Poke tongue | ;-P

), but at least give me a consistent answer or throw an exception if NaN is used in Math.Round()?

Again when my runtime was 1.0 it seemed fine, so could this be just a weird bug? Confused | :confused:

Correction: I have verified and this happens on both 1.0 and 1.1. Looks like an issue that no one has noticed before? Wink | ;)

Since Nan is not a real number, I wouldn't expect int casting to work predictably anyway. The easiest way around it is to check if a IsNaN before attempting the Round and int cast operations.

How Can I have an Label Control array of two dimensional On form.

How can I have any array of Labels on windows form? If I could Can I change them at form design ? Please any one knows kindly explain to me with example code.

Thank you,

You can't have control arrays on a form, however you can have an event handler that fires on multiple events from multiple controls providing they have the same signature:

this.button1.Click += new System.EventHandler(this.button_Click);
this.button2.Click += new System.EventHandler(this.button_Click);
this.button3.Click += new System.EventHandler(this.button_Click);
this.button4.Click += new System.EventHandler(this.button_Click);

private void button1_Click(object sender, System.EventArgs e)
	{
		//Some code...
	}

To change multiple controls at the same time at design time, click on the first, hold down CTRL and click on the other in turn, hit F4 and you'll get the properties that can be changes for all the selected controls at the same time.

Hope this helps

Tom

Passing ComboBox Items

Hi friends,

I would like to pass a combox.Items to other dialog form, because the dialog will have a combo which contains the same item collections of pervious form.
Suppose I have loaded all data classes from a folder to a combo, then now I going to pass the collection of data to other combo, what is the data type to pass then ?

e.g. using(SetupUIasf = new SetupUI(this.comboBox2.Items))
to ....
public SetupUI(ICollection datas)

am I right? or using ArrayList is better ?

thanks

Why not using ComboBox.ObjectCollection as that is what the ComboBox.Items property returns.

Properties Tab Shows a Blank White Page

kayhustle2-Dec-04 15:48

2-Dec-04 15:48

I noticed that if I opened up a particular solution the properties tab in the designer would just show a blank white page. If I go to another solution the page is still blank. I found that if I close .net and open up a different solution the properties tab is ok, but once I go to the other solution the tab is always blank even if i go back to the first solution. This is a pain in the ass. I redid my solution and remade the projects by adding the old source files and soon enough the properties tab would go blank and once it goes blank it always is blank for that particular solution. I am doing work that relies heavily on UI so I will need the designer. I am using .Net Enterprise edition, this is just unacceptable for a $2000 program. I know this is definitely a bug in the Visual Studio .net, especially since I have various other controls that are not showing right in the designer but they are showing correctly when I run the program. Does anybody know a fix for this?

See the SmtpMail class:

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfSystemWebMailSmtpMailClassTopic.asp?frame=true[^]

It's actually very easy. You set the server, the receipient, the sender, the subject, and the mail body. And then just send.

You should not use that unless you're running on a server or the machine has the SMTP Virtual Server installed with CDO configured correctly. SmtpMail uses a CDO server (CDO is a COM wrapper for MAPI, basically) and, thus, a CDO server must be installed. Currently Microsoft Exchange and Microsoft SMTP Virtual Services are two such CDO servers. Neither of those will run on Windows 9x/Me.

I didn't know that. Sorry! Unsure | :~

But, if my app will run only on Win2K and WinXP, is it ok? even on a Windows Forms application?

Thanks!

You need to make sure that Exchange/SMTP Virtual Server is configured right. If you need to forward to an external SMTP server, for example, you need to configure your local SMTP service to forward and make sure the other end accepts forwards for your host. There's a lot to consider when using an SMTP server.

Out of the box it may work for any code that uses SmtpMail but it really depends on your setup, which is outside the scope of this forum.
