Vince - Sounds like you are right on the money. Any managed dll coming from the internet is going to only run under partial trust.
Here is a great article on msdn that explains why this is and how to work around it for your web apps. The security stuff is the latter part of the article. http://msdn.microsoft.com/msdnmag/issues/02/01/UserCtrl/default.aspx Julie Lerman -----Original Message----- From: Unmoderated discussion of advanced .NET topics. [mailto:[EMAIL PROTECTED] On Behalf Of Vince Sanzone Sent: Thursday, October 07, 2004 7:59 AM To: [EMAIL PROTECTED] Subject: [ADVANCED-DOTNET] Winform in Web browser I am trying to implement a simple webform on a htm/aspx page and I am having some difficulty. I have searched through many messages on these boards and found a lot of references to this very thing, but I am still unable to get it working correctly. The result I get is the web page finding the dll but not being able to load it, I get a frame where the control should be with that little icon with the red square, green circle, and blue triangle. My UserControl looks like this. using System; using System.Collections; using System.ComponentModel; using System.Drawing; using System.Data; using System.Windows.Forms; public class FileManager : System.Windows.Forms.UserControl { private System.Windows.Forms.Label label1; private System.ComponentModel.Container components = null; public string TestMethod() { return "check check"; } public FileManager() { InitializeComponent(); } protected override void Dispose( bool disposing ) { if( disposing ) { if( components != null ) components.Dispose(); } base.Dispose( disposing ); } #region Component Designer generated code private void InitializeComponent() { this.label1 = new System.Windows.Forms.Label(); this.SuspendLayout(); // // label1 // this.label1.Location = new System.Drawing.Point(64, 40); this.label1.Name = "label1"; this.label1.Size = new System.Drawing.Size(208, 120); this.label1.TabIndex = 0; this.label1.Text = "label1"; // // FileManager // this.Controls.Add(this.label1); this.Name = "FileManager"; this.Size = new System.Drawing.Size(336, 200); this.ResumeLayout(false); } #endregion } And my htm page looks like this <html> <head> <title></title> </head> <body onload="fnLoad()"> <form id="hotform" name="hotform"> <object id="FileManager" classid="FileManager.dll#FileManager" width="100" height="100" VIEWASTEXT>Not working</object> <script language="javascript"> function fnLoad() { window.alert(document.hotform.FileManager); window.alert("before"); var hotString = document.hotform.FileManager.TestMethod(); window.alert(hotString); window.alert("after"); } </script> </form> </body> </html> As far as I can tell I am doing everything programmatically correct. Maybe there are some security settings that I am missing that are not allowing the control to load in the browser? Any help would be much appreciated.
