You are hiding your form, not closing. If you want to close your form use this.Close()
Also, if you have controls on the form, make sure that your form is processing key press until they reach the controls

Hi!
The simplest way is to assign the button your users are supposed to close the form (Cancel, Close, ...) to the CancelButton property of your form.

You can add a button on the form and close the form when that button is clicked. Then in the properties of the form find Cancelbutton property and set it to the button which closes your form.

ya its working.
but one doubt, if i need this same task to be done without
creating a button and setting its property to cancelbutton means , how ?
dont think i am irritating u

Allowing the user to close a dialog by using the ESC key only is bad UI design style, so if you keep up a good style and provide a button you don't face the problem.

how can i make a first character in the word an upper case, is there any predefined function that do this?
Yesterday is a canceled check. Tomorrow is a promissory note. Today is the ready cash. USE IT.

use following code
textBox3.Text = textBox3.Text[0].ToString().ToUpper() + textBox3.Text.Substring(1);
or
string s = "srinivas";
s = s[0].ToString().ToUpper() + s.Substring(1);
textBox3.Text = s;
|
|
|
|
|
There is no predefined method to do that. Use Substring to find the first letter, and use ToUpper() to make it upper case.
|
|
|
|
|
In addition to what the others have said, you may want to use the overload of ToUpper() that takes a CultureInfo.InvariantCulture parameter.
Cheers,
Vikram.

The methods ToUpper and Substring, as the others have said.

hi there,
today is my first exam of C# and other, some questions are confusing me, i dont have another way or time from where i can ask these question, so buddies please reply ASAP.
Q1.
A. In dynamic polymophism, appropriate methods of a program can be invoked, depending on the context.
B. In early binding(static), function calls are bound at run time.
a.) A true, B false
b.) A false, B true
c.) both true
d.)both false
Q2
is flow chart (OR and AND) rules are different from C#?
i mean in C# if we write like this:
if (a == 0 | a == 1)
{
//body
}
then any of is true(ie. a = 0 or a = 1)
then C# will enter the body.
is this will be same in flowchart or any other rule
i hope you people will understand what i wanna say.
please be in contact, more questions may asked
thanks

Q1 = A
not certain about second , i think it should be different but as we see it in logically meaning , it is true.but in representation it is different

This is wrong in the the case of C#.
if (a == 0 || a == 1)
{
}

man, its not time for joking. it will also work, i never use ||, i always use | and it works

It may work most of the time, but | is not same as ||. The compiler doesn't short-circuit the evaluation.
Please use the proper operator, for your successor's sake. 
BTW I am not sure if you do the same for & vs &&
if(a != null & a.Name != "abc") will throw you an "object reference....." exception.

yeah, i do but i never have any problem in using single (| and &)

Well then, I hope you will use the correct operator, else, you will have people in the future in your work asking (demanding) you to do so.
Also, it's is related to your original question. If you use bit wise OR or AND, each of them will be evaluated regardless (no short-circuiting). Beside, you will be doing AND or OR operations instead of CMP operation all the time.
|
|
|
|
|
|| is a logical or, the | a bitwise or (if I'm not mistaken)

thanks for your all, now its time to go
