What is the syntax for an not true or false if statement in nVelocity (or Velocity)?
And more importantly, where is this in the nVelocity docs? I've been Googling for quite a while to no avail.
I've tried several different combinations such as:
#if (!$artist.IsFestival)
$artist.FestivalName
#end
and
#if ($artist.IsFestival == false)
$artist.FestivalName
#end
So frustrating!
I have a fairly simple template that I need to make a method call from. However, NVelocity does not seem to evaluate method parameters that themselves are NVelocity variables. Take the following NVelocity template:
#if (--- CONDITION SNIPPED ---)
<blockquote class="column span-4">
I MADE IT!
</blockquote>
#else
<blockquote class="column span-4">
$extensionMethods.TestMethod(${var1})
</blockquote>
#end
In the above template, $extensionMethods is passed in as an instance of a class and works wonderfully when passing in evaluated numbers (e.g. $extensionMethods.TestMethod(4) works every time). However, using $var1 causes the entire string to be returned as-is: $extensionMethods.TestMethod(${var1}).
Is there a way to pass in a variable to a method lazily to get the above template to evaluate correctly?
I'm looking to use NVelocity in my ASP.NET MVC application, not as a view engine, just for rendering some email templates.However, I cannot for the life of me get it to work. I have downloaded it from the castle project and followed the example at [URL].html#step1No matter what I try I don't seem to be able to load a template located in my site. The example suggests using the absolute path, which I have tried to no avail:Template t = engine.GetTemplate("/Templates/TestEmail.vm");So please can someone give me two examples. One of loading a template located in the web site directory and secondly one parsing a string variable (as it is likely that my templates will be stored in a database).
View 3 RepliesI want to use "NVelocity" from plain ASPX pages without using any MVC framework. I don't want to use "NVelocity View Engine" thru' asp.net MVC framework. The only example that I got for "NVelocity" is for merging and writing onto console window (http://www.castleproject.org/others/nvelocity/usingit.html)
I am looking out for example on to integrating "NVelocity" into aspx web forms.
I am an experienced .NET developer with approximately 5 years of experience. Unfortunately, I have worked primarily on the back-end and as an desktop/smartclient developer. I have worked as a consultant for a total of 1 1/2 years on web development using both the MVP pattern and some Silverlight. I am wanting to develop a personal site, (My wife is due with our first in 7 months!) and figured while I was at it I would target particular technologies that I want to learn. Being that my current employer
uses Monorail with NVolocity and is plannning a migration to ASP.NET MVC with (most-likely) NVelocity, I figured that would be a good tech stack to use. In addition, I would like to add JQuery to the set-up.
I have done several ASP.NET MVC tutorials. Including one on this site (Great job!). However, adding NVelocity and JQuery to the mix muddies the water a bit for me.
So, my question is, does anybody have advice of where to start? Do you know of any good books, online tutorials, etc.? Do you think this is a good stack to use? Better view engine?
Is there any way to use placeholder similar to WebForms in NVelocity View Engine (.vm files)? Today I've got a component containing everything for the <head>, but I wish to specify additional tags from each view page like it can easily be done in ASP.NET WebForms / MVC:
<asp:Content ID="Content2" ContentPlaceHolderID="head" runat="server"></asp:Content>
If this is not possible directly trough NVelocity View Engine, do I have any other alternatives other than using a blank MasterPage and adding all markup in each view page?
I'm having problem in inserting text from a textbox in which user write or copy some text which may contain special characters ( " , . ) etc. If there is any special character it get conflict with CommandText Syntax and generates error in inserting. I want to insert all these characters. How could i do it?

The following CLR syntax works fine in my aspx page:
<%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="Website.MyBasePage`1[HomePageViewModel]" %>
But this C# syntax does not:
<%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="Website.MyBasePage<HomePageViewModel>" %>
Note, I am not using ASP.NET MVC, but this works fine if using System.Web.Mvc.ViewPage<> from ASP.NET MVC.
My MyBasePage looks like this:
public class MyBasePage<TModel> : Page where TModel : class {
public TModel Model
{
get { return (TModel)HttpContext.Current.Items["model"]; }
}
}
For reporting we used report RDLCs and displayed using an ASPX form. We implemented using the route as shown below. This resulted in forcing us to use the page route below and also to use the hyperlink instead of the normal Action Link. The question is how do we convert the asp:hyperlink ASPX syntax to Razor syntax.
//Custom route for reports routes.MapPageRoute( "ReportRoute", // Route name "Reports/{reportname}", // URL "~/Reports/{reportname}.aspx" // File );
<li><asp:HyperLink ID="hypReport" runat="server" NavigateUrl="<%$RouteUrl:routename=ReportRoute,reportname=StaffRpt%>">Staff Report</asp:HyperLink></li>
I am working with a sql server database with about 50 stored procedures. The database and stored procedureswere not created by me. The stored procedures all begin with a number in their name.
Example: 17P_Comsetter
The problem I am having is that if I try and execute the stored procedure at the command line in Query Analyzer,the query analyzer appears not to like that the stored procedure begins with a number. For example:
If I try an run the stored procedure as follows:
EXEC 17P_Comsetter
Then I get the following error message:
Msg 102, ..... Incorrect Syntax near '17'
I am using SQL server 2005. Does anyone know why I am getting this error message?

this is not working showing syntax error syntax error:operand is missing

Im trying to retrieve a path name from my Pictures table the pathname is stored under picturepath in my Pictures table I dont know how to join it on to my current sql syntax it uses the UserID which is set by a session.
And im unsure what goes in the commented line for my image url string?
using (OdbcCommand cmd = new OdbcCommand("SELECT Wallpostings FROM WallPosting WHERE UserID=" + userId + " ORDER BY idWallPosting DESC", cn))
{
using (OdbcDataReader reader = cmd.ExecuteReader())
{
test1.Controls.Clear();
while (reader.Read())
{
System.Web.UI.HtmlControls.HtmlGenericControl div = new System.Web.UI.HtmlControls.HtmlGenericControl("div");
div.Attributes["class"] = "test";
//div.Style["float"] = "left";
div.ID = "test";
Image img = new Image();
img.ImageUrl = String.Format("{unsure}", reader.GetString(unsure));
// this line needs to be represented in sql syntax
img.AlternateText = "Test image";
div.Controls.Add(img);
div.Controls.Add(ParseControl(String.Format("{0}", reader.GetString(0))));
div.Style["clear"] = "both";
test1.Controls.Add(div);
understand what is going on in the code line below:
Table t = (Table)Page.FindControl("Panel1").FindControl("tbl");
I understand Page.FindControl("Panel1").FindControl("tbl");
Why is there a (Table) before the Page.FindControl?

Basically, when the page loads i set the div visibility to false. When i click the button, i want the code behind function to be called, and the div tag to be visible, true.
$('#Button2').click(function () {
$('#edit').show(function () {
});
});
<input type="submit" id="Button2" runat="server" value="Search" OnServerClick="Button1_Click" />
but when clicking the button, the page posts back, causing the div tag to be invisible all times.
I can set the return false to the onlclick event of the button , but i need to call the function also.
tell me the use of Validaterequest False?
View 4 RepliesI'm using FreeTextBox HTML editor in some webforms in my asp.net project . if I do not set ValidateRequest property to false I get this error :
A potentially dangerous Request.Form value was detected from the client
It's OK in admin folder though , Because only authorized users have access to work with it . But how about public pages like sections where every users have access to leave comments(using FreeTextBox for collecting users comment ) ? Isn't risky for XSS Attack ? If the answer is not Yes , So what's ValidateRequest property for?

To reduce the loading time this blog we set generatePublisherEvidence to false in the app.config for executables.
<configuration>
<runtime>
<generatePublisherEvidence enabled="false"/>
</runtime>
</configuration>
Where do I set it for web apps? The blog that this does not go to the web.config. Where else should I put it?
