Custom Control with embedded graphic

[Dave Birchok via .NET 247]

I am developing a custom control for web forms using VS 2003. Iam putting the control in a custom control library project whichwill become a dll. This control uses a small bitmap. I don'twnat to have to copy the graphic file into each web project thatwill use this custom control. VS allows you to set the graphicfile's build action property to embedded resource. When thecustom control renders it will create HTML that I would like toreference the embedded graphic file. Is this possible?

Thanks,

Hi Dave,

Yes its possible. The most common approach is to write a handler to serve
embedded images from assemblies. ASP.NET's next version will have built-in
support for this. You can take a look at this article[1] which contains
enough info and detail about how it works and so it should serve as a
jumpstart for your own implementation in ASP.NET 1.x

Here is one way of retrieving embedded resource.
I don't know though how you can apply it to image. But I think that
this is possible.

' Retrieving XML-file from the embedded resources.
Dim thisExe As System.Reflection.Assembly
thisExe = System.Reflection.Assembly.GetExecutingAssembly()
' Replace "AssemblyName.FileName.xml" with the name of the
resource, as it is known in the assembly.
' Use the GetManifestResourceNames method of the Assembly
object to find the resource name.
Dim strFileName As System.IO.Stream = _
thisExe.GetManifestResourceStream("<Type Accembly Name
Here>.Reports.xml")
' Read XML.
Dim doc As XmlDocument = New XmlDocument()
doc.Load(strFileName)


WBR,
Andrei

I have a complete code for this if you would like... The last remaining part
of this is how do I use the embedded graphics at design-time? I know I could
create a custom designer for this, but is there any other way?
