Hello Friends, I have sharepoint services running on my Windows 2003 R2 Server. From VS2005, I created a sample web part like below (just to see how it looks). using System; using System.Collections.Generic; using System.ComponentModel; using System.Web.UI; using System.Web.UI.WebControls; using System.Xml.Serialization; using Microsoft.SharePoint; using Microsoft.SharePoint.Utilities; using Microsoft.SharePoint.WebPartPages; using System.Reflection; [assembly: AssemblyKeyFile("sample.snk")] namespace WebPartLibrary1 { /// <summary> /// Description for WebPart1. /// </summary> [DefaultProperty("Text"), ToolboxData("<{0}:WebPart1 runat=server></{0}:WebPart1>"), XmlRoot(Namespace = "WebPartLibrary1")] public class WebPart1 : Microsoft.SharePoint.WebPartPages.WebPart { private const string defaultText = ""; private string text = defaultText; [Browsable(true), Category("Miscellaneous"), DefaultValue(defaultText), WebPartStorage(Storage.Personal), FriendlyName("Text"), Description("Text Property")] public string Text { get { return text; } set { text = value; } } /// <summary> /// Constructor for the class. /// </summary> public WebPart1() { this.Title = "This is a test web part"; } protected override void RenderWebPart(HtmlTextWriter output) { output.Write(SPEncode.HtmlEncode(Text)); //Create a Label Label testLabel = new Label(); //Write the Text testLabel.Text = "Hello World"; //Add the label control to the page this.Controls.Add(testLabel); testLabel.RenderControl(output); } } } and my dwp file look like this <?xml version="1.0" encoding="utf-8"?> <WebPart xmlns="http://schemas.microsoft.com/WebPart/v2" > <Title>WebPart1</Title> <Description>WebPart1.</Description> <Assembly>WebPartLibrary1</Assembly> <TypeName>WebPartLibrary1.WebPart1</TypeName> </WebPart> I made "safe control" entry in the web.config file (c:\inetpub\wwwroot) like below.... <SafeControl Assembly="WebPartLibrary1" Namespace="WebPartLibrary1" TypeName="*" Safe="True" /> Also copied the WebPartLibrary1.dll to the c:\windows\assembly (GAC). Still when I try to drag the web part in a wep part page... I get error like below... "Web Part or Web Form Control on this Web Part Page cannot be displayed or imported because it is not registered on this site as safe." I have even reinstalled IIS and Sharepoint Servies. My sharepoint runs as (All Unassigned)". Can any body tell me what could be the reason for error and how to fix it. I am really struck up with this error. Thanks in Advance. TMRK T.Maria Raja Kumar
