Return type error

[mprice214]

Hi all, I have a button click event that is used to write a double used for offsetting another number in a form (ultimately to zero a display). Still struggling as a new user and having problem with an error: 'double WindowsApplication14.frmMain.btnZero_Click(object, System.EventArgs)' has the wrong return type Here is the function:

private double btnZero_Click(object sender, EventArgs e)
{
dblOffset = dblReceive * -1;
return dblOffset;
}

Can anyone let me know what I'm doing wrong here? Thanks. :zzz:

you cant use return type for click event. you should use void for click event. the signature of method that you can use for click event is: void methodname(object,EventArgs)

Do you have any suggestion for how I would get around this? Need to look at the current value of a double and then null it by clicking a button labeled "Zero". That is why dblOffset is equal to dblReceive * -1. I want to add dblOffset at that moment to dblReceive, which would then set dblReceive to zero. Thanks.
