which contains two int value, i want to add that int value and show up in the form4,

         f = Convert.ToInt32(labelofform6.Text);
         int g;
         g = Convert.ToInt32(fl.labelofform4.Text);

Can you tell us where is your label1 placed?

shaikh-adil 14-Dec-12 0:39am

it is in the sender form which is form6

i do not know the answer but, your label cant contain int value, it must be string value which you are saving and it must be previous int value,

yes you are right

Are you adding two integers or concatenating the strings?
f.ToString() + g.ToString() is like you are concatenating two strings.

i want to add and show that result in the form4's label, so how to do that?

Solution 1

fl.label1.Text= f.ToString() + g.ToString() ;

this line wont perform the mathematical addition its string addition
for eg:

C#

int f = 10;
int g = 20;

f1.label1.Text = f.ToString() + g.ToString() ;

o/p will be 1020 and not 30

For mathematical addition just add two int variable as below

C#

int f = 10;
int g = 20;

f1.label1.Text = Convert.ToString(f + g);

/EDIT

In your case Form4 f1 = new Form4() is a local variable which has an empty value or a default value for the member labelofform4.Text because you are not updating it.

second you said its not working I dont see any code to display the form4 was is not included for any purpose?

so how to the mathematical addition?
sorry that will be a silly mistake but i am a student now, trying for learning .net
and BTW it is not giving 1020 also in the form4's label

Jibesh 14-Dec-12 0:59am

there are lot of error in your code. You must understand what is local variable and what is member variable.

In your case Form4 f1 = new Form4() is a local variable which has an empty value or a default value for the member labelofform4.Text because you are not updating it.

second you said its not working I dont see any code to display the form4 was is not included for any purpose?

come with your default values and exepected result. do read your code once again!!!

Jibesh 14-Dec-12 0:52am

check my updated solution. if that didnt satisfies your answer write the expected result and what result your getting.

Solution 2

C#

int f = 10;
int g = 20;
int sum=0;
sum=f+g;
f1.label1.Text = Sum.ToString();

//u r trying to add string f1.label1.Text = f.ToString() + g.ToString() ;
//not the actual value
