[RESOLVED] timer on winform

[Niya]

While I agree with everything jmc said, I'll still provide this incase you still want to use it.

#region "BlinkLabel"
 
public class BlinkLabel : Label
{
 
    private System.Windows.Forms.Timer g_objTimer = new System.Windows.Forms.Timer();
    private int g_iBlinkTime = 0;
    private bool g_bVisible = true;
 
    private bool g_bIsBlinking = false;
 
    private bool g_bDefaultVisible = true;
 
    [System.ComponentModel.DefaultValue(true)]
    public new bool Visible {
        get { return g_bDefaultVisible; }
 
        set {
            g_bDefaultVisible = value;
 
            if (base.DesignMode == true) {
                base.Visible = true;
            } else {
                base.Visible = value;
            }
 
            if (g_bDefaultVisible == true & g_bIsBlinking == true) {
                g_objTimer.Interval = g_iBlinkTime;
                g_objTimer.Enabled = true;
 
                //Remove any previous handlers
                g_objTimer.Tick -= Elapsed;
                g_objTimer.Tick += Elapsed;
 
            }
 
            if (g_bDefaultVisible == false & g_bIsBlinking == true) {
                g_objTimer.Enabled = false;
                g_objTimer.Tick -= Elapsed;
 
            }
 
 
        }
    }
 
    [System.ComponentModel.DefaultValue(0)]
    public int BlinkTime {
        get { return g_iBlinkTime; }
 
        set {
            g_iBlinkTime = value;
 
 
            if (base.DesignMode == false) {
 
                if (g_iBlinkTime != 0) {
                    //If the control's visible property is false
                    //go into blink mode but dont show the control
                    if (g_bDefaultVisible == true) {
                        g_objTimer.Interval = g_iBlinkTime;
                        g_objTimer.Enabled = true;

                } else {

                    base.Visible = g_bDefaultVisible;
                    g_bIsBlinking = false;
                }
            }
        }
    }
 
 
    private void Elapsed(object sender, System.EventArgs e)
    {
        if (g_bVisible)
            g_bVisible = false;
        else

Its a BlinkLabel I wrote some months back for the exact same reason that you want it. I used it for a "Please wait" message while waiting for an SMO query for database instances to complete. Just use it like a normal label and set its BlinkTime property to something greater than zero for it to start blinking. I suggest 500(which is 500 milliseconds). Anything else seems too slow or too fast but then thats a matter of preference.

Trivia: This was written in VB.Net....just used an online converter to get C# code.
