dont create the variable in the form load event.
create a separate class in the namespace of the old form
once you have done that, u can use the variable using the classname and the dot operator.
as classname.variable name
like, mySeparateClass.globalVariable1

One metod is to create a new metod to show the new form.
public void myshow(object param)
{
this.Show();
this.param=param;
}
|
|
|
|
|
you can access that variable in any form, using the class name

No. You can't. He described an instance field. Not a static field.

Overload default constructor of the new form and pass the old form object to this constructor. Use that object to access the value
|
|
|
|

Can you can show me more clearly? May be give me some code? I'm a beginner. Thank you very much!
|

namespace Sample
{
public partial class Form1 : Form
{
}
// create a separate class here
public class mySeparateClass
{
public static int globalVariable=new int();
}
}
Once you have done that, u can access the variable globalVariable, anywhere in all the forms of the project using the classname as follows.
mySeparateClass.globalVariable
try it.;)

Global variables are generally an indication of a poor design. If you feel compelled to use a global variable your first thoughts should be: Is there a better way to do this? If not, then fine, use the global variable. But they should not be your first option.

Please show me how to creat a variable that can use in all form in my project.I'm learning C#.NET 2005.
|
|
|
|
|
create a separate class like below
public class mySeparateClass
{
public static int globalVariable1 = new int();
}
then you can use the variable globalVariable1 as mySeparateClass.globalVariable.
check it out.
i hope this works.

Declare a variable as static
public static int myvar=1;

I'm a beginner. I opened a new form and want to close old form. But I don't know how to close old form. Help me!
Thank you everybody.
|

You can hide the old form
Form2 form=new Form2();
this.Hide();
form.Show();
... but it is a problem if you close the form2 the program run in background
|
|
|
|
|
ya so when form2 is closed,
please use a similar piece to show any other form, from which u can proceed.

if you want to close the application you need to use
Application.Exit();
|

Don't close the form where static void main is there. Entire application will be closed !!!!!!!!!!

Hello All,
While creating a database, i have to issue the following command.
CREATE DATABASE Logger1 ON PRIMARY (Name = test_data, filename ='C:\\mydb_data.mdf', size = 3, maxsize = 5, filegrowth = 10%)log on (name = mydbb_log, filename = 'C:\\mydb_log.ldf', size = 3, maxsize = 20, filegrowth = 1)
Please note that the max file size while creating the mdf file is 5MB and the max file size while creating the ldf file is 20MB.
I dont want to restrict it to a finite value.
By default when a database is created through GUI, it has an unrestricted file size.
so in the same way, can someone please tell me what should I provide as maxsize to have unrestricted growth.
any help would be useful

I wasn't aware that you had to supply a max size value. Just leave it out.
