opacity reduce by button click

[Guest]

Hi,

what is the code in C# for reduce the opacity every click on the button to
0.1, example:
the opacity is 1.0 for 100% i need to go down from 1.0 to 0.0(0.9,0.8,0.7
etc )?

float fltOpa = 1;

private void button1_Click(object sender, EventArgs e)

{


this.Opacity = fltOpa;

fltOpa -= 0.1;

}

{


this.Opacity = fltOpa;

fltOpa -= 0.1;

if (fltOpa < 0.0) fltOpa = 0.0;
