Hi,
I've put a appSetting tag into my web.config, but when I try to catch its
value to my Image WebControl occurs the follow error: "Server tags cannot
contain <% ... %> constructs."
on myPage.aspx (Notice the ImageUrl tag):
<asp:Image id="Image1" runat="server"
ImageUrl=<%=Sys tem.Configurati on.Configuratio nSettings.AppSe ttings["SrcImgSi
stema"]%> />
So, What's wrong with my ImageUrl attribution?
Is there any way to do that?
thanks a lot

you can set this property programmaticall y within a server script block:
Image1.ImageUrl =
System.Configur ation.Configura tionSettings.Ap pSettings.....
you cannot use <%%> inside a web control as web controls already run at the
server.

i don't know of any way, and there is no reason to do it inside the html
section.
one of the ideas behind web controls design, is the separation of code from
html.

In your code there are some errors :
The <%= construct can only be used in client script for write some value
from server (like old ASP).
your Image is server side not in client side!!!!
You can use the <%# construct. This is for binding value!
<asp:Image id="Image1" runat="server"
ImageUrl='<%#Sy stem.Configurat ion.Configurati onSettings.AppS ettings["SrcImgS
istema"]%>' />
this code require a DataBind() method call!!!

In ASP.NET 2.0 not only can you refer to appSettings declaratively (without using the DataBinding syntax), which is precisely what you are trying to do here, but you can create an ExpressionBuild er that lets you run arbitrary code declaratively, which is precisely what you tried to do.

Hi,
I have a query.
All html tags start with < and end with >. Suppose i want to display either '<' or '>' or say some text like '<Company>' in html how do i do it?
One method is to use <, > ,<Company> to display '<', '>' and '<Company>' respectively.
But is there any freeware code available which could implement the above functionality without having to use >,< and such stuff???

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows.
