Is there a way to detect if the client is capable of playing Flash animations?

Read the solution here. This guy had the same problem.

Thanks... It works now.

Have you checked that IIS is running? I had the same problem and the solution was to activate the IIS and to reinstall the .NET Framework.

I am trying to make a simple control with a button and a label. When you click the button the text of the label should change from "A" to "B" but it doesn’t work. Can anybody tell me what am I doing wrong? using System; using System.Web.UI; using System.Web.UI.WebControls; using System.ComponentModel; namespace WebControlLibrary1 { [DefaultProperty("Text"), ToolboxData("<{0}:WebCustomControl1 runat=server>")] public class WebCustomControl1 : System.Web.UI.WebControls.WebControl { private Button b; private Label l; public WebCustomControl1() { b=new Button(); b.Text="Click me!"; b.Click+=new EventHandler(this.b_Click); l=new Label(); l.Text="A"; } private void b_Click(object sender, System.EventArgs e) { l.Text="B"; } protected override void Render(HtmlTextWriter output) { b.RenderControl(output); l.RenderControl(output); } } }
