I am developing a web application where users can draw their own images in a web page using canvas. After it's drawn, this image should be shown in other users' browsers' canvas. Same thing with updates.I am only using javascript. How can i solve this problem using System.net and Asp.net?
View 1 RepliesI would like to know if there is any way to draw some dynamic number of points and lines in a report.
I will have a group of "coordinates" that will define where in the report I must draw the items (cm from the left, and cm from the top).
Is there any way to achieve that? I can draw fixed elements, but I want positioning them dynamically.
The final target is to draw a map which mantains a scale, and draw some relevant elements in the map.
I'm thinking to have a datasource with all the location, the appearance and text data, and then (still don't know how) draw each element with it's style.
I have a new web application I'm trying to create. I'd like to put some automation into how it propagates upcoming dates. Here is the way I'd like it to function.
I have three tables:
Managers
- id
- netid
- phone1
- phone2
- username
Monthvals
- id
- monthname (Friendly like December 2010)
- monthval (shortdate like 2010-12-01 00:00:00)
Weekends
- id
- weekend_val (date of the friday)
- month_id (Monthvals.id)
- mgr_id (Managers.id)
The tables I need to create SPs for are monthvals and weekends that will build the upcoming year. This is where I'm kind of stumped.
The spec for this is each manager gets assigned a weekend every 35 days with the exception of two which alternate so in that case, every 70 days.
What I need this SP to do is based on the activity in December or the last six weeks, I'd like it to write out a schedule for the following year. I don't mind writing this out but I could really use some psuedocode to iron out what I'm trying to do.
I have an asp.net (FW 3.5) web app that runs on an internal network. One specific page needs to "report" in to the web server that it is active and not locked up. I need to be able to run a script (or something) at the client to report the pc's computer name in that report. I cannot find a method that does this. I found several things that would report the WAN IP or host name, but this appears to all be for external facing sites.
View 1 RepliesI am running a website from IIS on one computer and I want to view the web page on another computer. the only way I can do this is by using the ipaddress of the computer with IIS on it but would rather have a url. How can I generate a url or use a domain name from [URL]. I signed up for an account on that website but dont know how to use it. I dont know how to configure it.

View 1 RepliesI'm trying to port an ASP.NET MVC 1.0 / Visual Studio 2008 project to ASP.NET MVC RC 2 / Visual Studio 2010. The project is (and has always been) running on IIS 7.
Dynamic content (everything that's being delivered by controllers) works fine, but static content such as CSS / Javascript / Images gives me a "200 OK" response, a Content-Length of 0 and no content. It's as if all those files were entirely empty (I made sure the files are not empty though).
The static content is in a directory that I excluded from ASP.NET routing via IgnoreRoute.
It can't be a hidden 404 error since adding some garbage characters to the URL produces a reguar 404 error.
It doesn't seem to be related to filesystem permissions since I've already given everyone full access rights in the contents directory.
Edit: I just created a completely new ASP.NET MVC website from scratch and tried running that in IIS. It has exactly the same problem! So it's not really a problem of converting my project to MVC2 at all, it rather seems to be IIS that's causing the trouble. But what could possibly be the problem?

i have a navigation bar made up of ImageButtons that have their image swapped out on mouse over and back on mouse out. i used this code in the Page_Load handler to do this:
ImageButton1.Attributes.Add("OnMouseOver", "this.src='mouseover.gif'")
ImageButton1.Attributes.Add("OnMouseOut", "this.src='mouseout.gif'")
what i'm trying to do now is get the mouseover image to load when you click the button and are taken to the page. i tried this but it doesn't work:
ImageButton1.Attributes.Add("OnClick", "this.src='mouseover.gif'")
I have been looking for the best way to obtain the total number images in a folder where the first two characters on the file name are XX and place this number into a variable.So for example - I have a folder containing the following images:
XX-01.jpg
XX-02.jpg
XX-03.jpg
YY-01.jpg
ZZ-01.jpg
So I would populate the variable with 3 in this case.Does anyone know of any way to do this?

i have implemented an image preloader using javascript inside my mvc 2 web app, in order to display an animated "loading" image .gif while sequentially displaying page images.I have also implemented caching using a cache profile for the controller action that displays the specific page ([OutputCache(CacheProfile = "LongCache")]).The problem is that the image preloader javascript is called when caching is applied. I was wondering whether i could, somehow, use the image preloader code only when the page gets refreshed and not when the cached version is rendered.
View 2 RepliesI am looking for a control that can draw a very customized chart in ASP.NET. The chart comprises:
1. A closed triangle, or polygon, shaded, drawn according to a fixed set of xy vertices.
2. A series of x,y points plotted on top of the triangle or polygon.
I thought the chart Control wasthe best, but I can't figure out how to draw the close triangle or polygon.
Is GDI+ the better way?

View 1 RepliesIs it possible to edit images using a javascript library and then send the edited image to the server for saving.
Edits will be in real time, means the user can see the edit result in the same time he is editing without the need to refresh the page.
I want a javascript library to do some edits on an image on a webpage 'such as crop, resize, rotate,...' and send send the edited result to the server.
Okay, so this is one of those annoying bugs that happens sometimes, but not with enough regularity to really root out.
Fair warning that I'm still just toddling in ASP.NET, so I could be doing something heartbreakingly stupid. Here's the gist:
I've got a page with the bulk of its content inside of a TabContainer from the AJAX Toolkit. There are a few page elements outside the TabContainer -- mostly just header/footer stuff from the master page. Sometimes the page will load (either initially or on a postback) and the TabContainer will completely fail to draw, leaving a mostly-empty page. Clicking "Reload" in the browser almost always makes everything appear as usual.
What would make a TabContainer occasionally fail to draw? How can I go about debugging this.

How would I go about centering text onto an image? I am guessing it would have to do with defining some sort of container (rectangle maybe?) that is the width of the image and centering the text within that? Not sure what the best practice would be for this.
I'm currently programming an application in ASP.net MVC and I'm looking for a plug-in or anything that will to draw some rectangles and manage them. The rectangles should be resizable, movable and they should be compose of 8 points (at the middle of each corner and at each corner). I already found SVG, HTML 5(canvas) and [URL].
