ASP.NET Discussion Boards

Well I've been working on this all morning. And your right, it was my calculation and I did get the Graphics and Bitmap objects right.

So after hours of using my calculator and confirming formulas, I had nothing. Then I decided to search for the same formula but written better and came across this. I looked at it and deemed it to be highly optimized already.

Well at least I got the thought right about canvas, ratios, positions, for the code just slid right into my code.

Thanks Richard, it was head scratcher. But I went with this instead.

On the positive side, I must admit that this function is pretty slick now that it works correctly.
Working with images as byte arrays is pretty cool for storing them in the database and writing them as files for HTTP calls.

On the negative side, working with numbers in c# is much different that VB. C# doesn't divide integers, didn't know that.

graphicObj.Clear(Color.Transparent);
graphicObj.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.Default;
graphicObj.InterpolationMode = System.Drawing.Drawing2D.InterpolationMode.High;

// Figure out the ratio
double ratioX = (double)canvasWidth / (double)originalWidth;
double ratioY = (double)canvasHeight / (double)originalHeight;
// use whichever multiplier is smaller
double ratio = ratioX < ratioY ? ratioX : ratioY;

// now we can get the new height and width
int newHeight = Convert.ToInt32(originalHeight * ratio);
int newWidth = Convert.ToInt32(originalWidth * ratio);

// Now calculate the X,Y position of the upper-left corner 
// (one of these will always be zero)
int posX = Convert.ToInt32((canvasWidth - (originalWidth * ratio)) / 2);
int posY = Convert.ToInt32((canvasHeight - (originalHeight * ratio)) / 2);

// Create the new Image Object
graphicObj.Clear(Color.White);
graphicObj.DrawImage(image_in, posX, posY, newWidth, newHeight);

// Save the Graphic Object
graphicObj.Save();

when im trying this code in MVC4 Getting an error..
The name 'ObjectFactory' does not exist in the current context

using eManager.Domain;
using eManager.Web.Infrastructure;
using StructureMap;
namespace eManager.Web {
public static class IoC {
public static IContainer Initialize() {
ObjectFactory.Initialize(x =>
{
x.Scan(scan =>
{
scan.TheCallingAssembly();
scan.WithDefaultConventions();
});
x.For<idepartmentdatasource>().HttpContextScoped().Use<departmentdb>();
});
return ObjectFactory.Container;
}
}

Just going out on a limb here, but I think you may have a "public class ObjectFactory" instead of a "public static class ObjectFactory".

Thanks problem is solved

Are you using ObjectFactory from StructureMap?

Thanks..solved it

were you missing StructureMap reference? how did you resolve it?

C#

I have a one data grid that returns datasets with different headings depending on the selection by the user.

I have search online in CodeProject but could not find a similar solution. Most had hard coding for the headings.

Please advise with examples on how to freeze heading

I am using .Net 4.5 with Microsoft Visual Studio Professional 2013.

This datagrid was developed in .Net 1.1 and migrated to .Net 4.5.

I am new in MVC. I have some views where there is no need of controller they are static views just some information to be displayed. i searched the web and found (View Without Controller Action in MVC[^]. My controller look like

C#

public class PublicController : Controller
    {
        // GET: Public
        protected override void HandleUnknownAction(string actionName)
        {
            try
            {
                View(actionName).ExecuteResult(this.ControllerContext);
            } 
            catch (Exception e)
            {
                Response.Write("PageNotFound");
            }
        }
    }

i added an entry in routeconfig file as

C#

public static void RegisterRoutes(RouteCollection routes)
        {
            routes.MapRoute(
                name: "Default",
                url: "{controller}/{action}/{id}",
                defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
            );
            routes.MapRoute(
               name: "NoAction",
               url: "{controller}/{action}/{id}",
               defaults: new { controller = "Public", action = "HandleUnknownAction", id = UrlParameter.Optional }
           );

        }

and i am calling the view from me menu in my master file as

HTML

<ul>
                                <li><a href="@Url.RouteUrl("Public", new { name = "History.cshtml" })">History</a></li>

My history.cshtml file is inside "Public" folder and my controller name is PublicController, i also have pagenotfound.cshtml file which is also in public folder but it always shows me PageNotFound.cshtml file. I dont know how to call my view from my menu. Please help Thanks

The correct syntax for @Url.RouteUrl is

C#

Url.RouteUrl("LinkName", new { controller = "ControllerName", action = "MethodName" })

You need to have a method in your controller matching your view. This is by design from MVC. If you have something inside another folder , then it has to match your controller.

I would recommend you read the concept of MVC before writing this code.

You may also use Areas for folder. Learn areas in MVC too.

I am adding html templates to actionmethods in views.and i have added JS folder,CSS folder.in route config file i have set index as main page.only for mainpage Jquery and css is applying but remaining pages it is not applying.if i changed route config file with another index2 css is applying on Index2.can you please tell me what are ways to solve this?

Follow the instructions here. if you still can't get it working then you have to post the code in Q&A.

The error is self-explatory. Your view expects a list of Employee objects so it will be something like

C#

@model IEnumerable<Employee>

yet you are passing only a single Employee object. We can't tell you how to resolve this as we don't know your business rules. If your view caters for multiple employees but you only want to pass one employee then change the action to something like

C#

return View(New List<Employee>{source});

As the error suggests , you are passing Employee Entity whereas it expects IEnumerable.

2 partial views connect to index view but first partial view have display data(name,datein,compliant where status = "new") and the submit button.once click the submit button (the status value changed to "Received")refresh the page and display the same data(name,datein,compliant)

if u have any examples related this can u plz send me or guide me if u have any idea.thankyou all who r helping me.

You have already posted this question, received an answer, and accepted the answer:
In MVC how two partial view connect to indexview[^]

"These people looked deep within my soul and assigned me a number based on the order in which I joined."
- Homer

The partial view just needs a form around the submit button etc whose action points to the action that generated the parent view and whose method is post. Submitting the form then posts the data to that action which will process it and return the view as normal.

This is all incredibly basic MVC stuff, you'd be best going through a book on MVC to learn the basics and how to do these things will become clear.

use of select command to fetch(Resume) Record into table

Yes it is.

Not clear. what you exactly want ?

Hi..Im Beginner in asp.net mvc4..pls can you help me ..im trying to learn AutoMapper using EF..can you provide me your valueable guidance ..how to code AutoMapper..
