I need to get an image from a SQL Server as a byte[], and load it to a WebControl.Image. The only seemingly good way to do it that I found is to implement IHttpHandler and handle the request accordingly.But I'm stuck to using asp.net 1.1. Does it support ashx files?
View 1 RepliesWith regards to the Razor view engine, say I want to render Html.TextBoxFor<SomeModel>(i => i.Name), it doesn't seem that the inline syntax works as in:
@Html.TextBoxFor<SomeModel>(i => i.Name)
This doesn't seem to work because it interprets the generic as an HTML tag. I could use a code-block approach, but then what's the best approach to output the content? The HTML string returned from this method, do I response.write it, or is there a syntax for it, or what's the approach?
I have a bit confusion about the Http Handlers,Generic Handlers and the usage of those two.
View 1 RepliesTrying out the Razor view engine and for some reason my generic helper methods are breaking. For example:
public static class UrlHelperExtensions
{
public static string NonGenericHelper(this UrlHelper helper, Type controller)
{
return controller.Name;
}
public static string GenericHelper<TController>(this UrlHelper helper)
{
return typeof(TController).Name;
}
}
Works as expected:@Url.NonGenericHelper(typeof(ProjectEuler.UI.Models.Home))Breaks with the following exception:
@Url.GenericHelper<ProjectEuler.UI.Models.Home>()
"CS1502: The best overloaded method match for 'Microsoft.WebPages.WebPageUltimateBase.Write(Microsoft.WebPages.Helpers.HelperResult)'
has some invalid arguments"
The only workaround I could find is treating it as a "multi-token
statement":
@(Url.GenericHelper<ProjectEuler.UI.Models.Home>())
Not sure if this is the intended behavior or just a bug but it would be nice to be able to call a generic method as you would a non generic one.
I wrote a generic handler like this:
[Code]....
and on the other page I would like to retrieve the database image using :
<img alt="" src="ShowImage.ashx?ID=467711" />
but I am getting nothing in this case. The picture exists and there are 91000 bytes in array.

View 1 RepliesI am using a generic handler (indicator.ashx) to create a graphic that is overlayed from information from a table (called LIVE) from our SQL database. This is working very well and I am very happy with the results.
However I am having an undesirable issue where the query string that is used for this is also being accessed by another page (called ReceiveLive.aspx) which is populating our LIVE table with data when we don't want this. I have been able to track this issue down to our generic handler that seems to populate this table with data whenever the handler is accessed.
The query string that is used to access our graphic through our generic handler is
http://mydomain.com/indicator.ashx?ID=ABC001.
Our other page that writes data to our LIVE database used the query string
http://mydomain.com/live.aspx?ID=ABC001 which is normally only accessed by a small piece of software that sits on the users PC and sends the data when necessary.
My question is this: How do I prevent data from being written to our LIVE table via the Live.aspx page everytime a query string is processed by my indicator.ashx is accessed?
I'm trying to create a control out of a class I found, and one of the overridden functions is the following:
protected override void PerformDataBinding(IEnumerable data)
However, when I try to build the control I'm getting the error as shown in the subject. I've tried searching, and it seems the signature for the original function matches the one I have, and all other solutions I've seen uses the same signature.
What is the difference between generic and non-generic collection?
