Hi all,
I have a form that when loaded begins to write to a serial port. On closing the form, the serial port is closed. When I click the "X" button to close the form, the form stays open, but the data from the serial port discontinues. However, to get the form to actually close, it will not do so until I right click the form's pane in the taskbar. Not sure why this would be happening....
private void frmMain_FormClosing(object sender, FormClosingEventArgs e)
{
if (_serialPort.IsOpen) _serialPort.Close();
}

Set a breakpoint on the if and debug.

Is your form modal? The x button behaviour may vary based on this. See here.

There are two buttons (Button1、Button2) and one TextBox in the winform,I have two questions as below:
1、I want to the execute the button1_Click event when clicking the button2_Click?
2、when the text of textbox1 is changed, then call the button1_Click event, how to write in the textBox1_TextChanged?
thanks in advance,pls give the codes in detail.
(Don't use this method: place all the codes of button1_Click in one method then use this method in button2_Click)

Hi,
I know of 3 solutions:
1. put the logic in a simple method which gets called by all interested handlers, so have button1_Click and textBox1_TextChanged call the simple method;
2. call button1_Click() with 2 dummy arguments; maybe null, null is sufficient; maybe this, new EventArgs() is needed. In both cases, they do not really carry much information.
3. some actions can easily be simulated, try button1.PerformClick()
Most of the time I prefer #1.

I often us the this.button_click(null, null). Commonly, these two parameters of the method of button_click are no use.

That's not the best method to do it. Luc's number 1 response is the best way to do it since the code you write in other places doesn't have to know that it's passing bogus parameters to a method that doesn't even require them.

There are some 50+ CodeProject articles about artificial intelligence. Did you read any of them?

Or you could always pick up and read a book on artificial intelligence....

Well, I'd start off by sitting down and working out what my detailed requirements are; but I'm funny that way.

I have a question... is it possible to develop a flight inquiry application using C# only and web services maybe, or I should register to some service in order to connect and read the flight details?

you should register with some service to get the flight details.

hi guys,
I am looking for ways to study for the exam 70-536 and 70-528. Is there any book that give you chapter based questions and have test questions. Perhaps a workbook or practice book. I am bascialy looking something like Exam-Cram but there isn't any.
Thanks

I doubt anybody here knows what that means. If they do, you are lucky. Perhaps you should elaborate.
