ถามเรื่องตอนรัน win app ของ c#.net หน่อยครับ ถ้าเป็นโปรแกรมที่มีการ Loop ไม่มาก ตอนโปรแกรม process ถ้าเอาไปคลิกก็ไม่มีปัญหาอะไรหรอกครับ
1. วิธีกากสุด เอา Application.DoEvents() ไปใส่ในลูป เช่นCode (C#) private void btn1_Click ( object sender , EventArgs e )
{
for( int i = 0 ; i <= 10 ; ++i )
{
Application.DoEvents();
System.Threading.Thread.Sleep( 1000 );
this.Text = i.ToString();
}
}

ไม่ต้องถึงกับ parallel ก้อได้ค่ะ แยกเขียน loop แบบ long time process ไปเป็นแบบ asyncronous thread ก้อได้
