Web Custom Control - Retrieve Images from a Multifile Assembly

M

MLibby

How do I store an image and a web custom control's dll in a multifile
assembly so that the image can be retrieved and displayed while the control
is in design mode? This would allow the control to display a company logo
while in design and ensure that the logo's image file does not get deleted or
lost causing design mode problems.

I know that the possibility exists to have multifile assemblies which are
inclusive of the dll and other files. I found an example showing a web
application that retrieves text from a resource file embedded within a
multifile assembly. I can't find anything that deals with retrieving images
from a multifile assembly though.

Desired code example below:

using System;
using System.Web.UI;
using System.Web.UI.Design;
using System.Web.UI.WebControls;
using System.ComponentModel;
using System.ComponentModel.Design;

namespace CustCtrlDesigner
{
/// <summary>
/// Summary description for CustCtrl.
/// </summary>

[DesignerAttribute(typeof(CustCtrlDesigner), typeof(IDesigner))]
public class CustCtrl : System.Web.UI.WebControls.WebControl
{
protected override void Render(HtmlTextWriter output)
{
output.Write("<center><font size='30'>");
output.Write( "Rendered!");
output.Write("</font></center>");
}
}

public class CustCtrlDesigner : System.Web.UI.Design.ControlDesigner
{
public override string GetDesignTimeHtml()
{
// Retrieve multifile assembly image here ! ! ! ! !
string html="<img src=''>";
return html;
}
}
}

Hello,

I think the VS.NET IDE cannot display the image directly from the assembly.
It displays the HTML code like IE. The image should have an actual location
when it is displayed. I suggest you may exact the image from the asembly
file, save it in a temporarily folder and generate a link string pointing
to it. For exacting a image from a assembly, you may refer to this article:

Hope this help,

try TStreamImage control, it has design time support (be sure to read docs
included)
