Where does ASP.Net get its rendered IDs from?

Hi, I've inherited a project with some nasty JavaScript that depends on hard coded object ids. i.e. There are lots of places where it does things like this var magazine = document.getElementById('repModuleDisplay__ctl3_chkCats_0'); When the page renders in my UAT environment, the HTML looks like this, and everything works OK. <inpu...

The spec can be found at: http://opensocial-resources.googlecode.com/svn/spec/1.0/Social-Data.xml#Person In the 1.0 data specification there is no XSD and no examples showing the use of this generic P...

Using IVMRWindowlessControl to display video in a Winforms Control and allow for full screen toggle

I've recently switched from using the IVideoWindow interface to IVMRWindowlessControl in my custom Winforms control to display video. The reason for this was to allow zoom capabilities on the video within the control. However in switching over, I've found that the FullScreen mode from IVideoWindow is not available and I am currently try...

Why when I render a scene with a revolving camera objects that you'd expect to appear behind others don't do that? OPENGL Objective-c

Hello, I am rendering a scene in which I have two spheres. I am revolving a camera around one of them. What happens is counter-intuitive. When the camera goes around the sphere the other gets in front of it when you'd expect it to be behind. So it appears as though the spheres aren't revolving around each other and the one the should go ...

Generate "spherical" panorama in 3D software

Lets say I have a 3D model of room in some format. How can I programmatically render "spherical" panorama from some point of room (kind of like the "Google street view" uses)? I suppose it can be done in Blender? It's better if it will be done in Linux. ...

Web Page Rendering Capture

I start with describing the problem itself. Rather than a problem I'm looking for a better solution. I have a asp.net page which has a bunch of images and a link underneath it, Each image is infact the latest rendering of the link underneath it. I scheduled a bat script which runs every hour to fetch the images through IECapt a web page...

Does margin-left:2px; render faster than margin:0 0 0 2px;?

Douglas Crockford describes the consequence of Javascript inquiring a node's style. How simply asking for the margin of a div causes the browser to 'reflow' the div in the browser's rendering engine four times. So that made me wonder, during the initial rendering of a page (or in Crockford's jargon a "web scroll") is it faster to write...

Removing UITextField from superview does not make it disappear on screen

I have the following code // Breakpoint here [label removeFromSuperview]; [label release]; label = nil; stepping through it with the debugger outputs (gdb) po [self subviews] <NSCFArray 0x476af70>( <UIImageView: 0x47581a0; frame = (0 0; 232 81); opaque = NO; autoresize = W+H; userInteractionEnabled = NO; layer = <CALayer: 0x476b3d0>>...

PyOpenGL: glVertexPointer() offset problem

My vertices are interleaved in a numpy array (dtype = float32) like this: ... tu, tv, nx, ny, nz, vx, vy, vz, ... When rendering, I'm calling gl*Pointer() like this (I have enabled the arrays before): stride = (2 + 3 + 3) * 4 glTexCoordPointer( 2, GL_FLOAT, stride, self.vertArray ) glNormalPointer( GL_FLOAT, stride, self.vertArray + 2 ...

WPF: Improving Performance for Running on Older PCs

So, I'm building a WPF app and did a test deployment today, and found that it performed pretty poorly. I was surprised, as we are really not doing much in the way of visual effects or animations. I deployed on two machines: the fastest and the slowest that will need to run the application (the slowest PC has an Intel Celeron 1.80GHz wi...

How do I integrate a BSDF into a ray caster.

I'm trying to implement sub surface scattering at isosurfaces and looked up how a BSDF works mathematically. Implementing the reflective and diffuse part seems to be quite easy as i just have to evaluate phong at the isosurface intersection, but how do you I apply the transmissive part of the BSDF? In what way do i have to modify the r...

PHP to Mesh 2 PDF'S Together or not?

I have an already pre-designed PDF, and I would like to fill the PDF with some database information. So I'm curious if I should save the PDF into JPG's and render them out with the data on top of the image and re-create a PDF. Or is there a way to use the PDF already, and print data into the PDF that is already made? I am trying to fi...

Javascript (and HTML rendering) engine without a GUI for automation?

Are there any libraries or frameworks that provide the functionality of a browser, but do not need to actually render physically onto the screen? I want to automate navigation on web pages (Mechanize does this, for example), but I want the full browser experience, including Javascript. Thus, I'd like to have a virtual browser of some so...

Can you recommend an in-browser Ruby/Rails 3D renderer?

I want to draw some 3D network diagrams in a web browser, and the data for these diagrams are in a Rails app (in the database). I already use flotomatic as a Rails interface for pretty Javascript plots (e.g., independent variable, dependent variable). Certainly there are packages for drawing simple things in Javascript. What I'm lookin...

I have a few dynamic pages and I want to alter certain elements before the page has fully rendered. My snippet is something like document.body.getElementById("change").innerHTML = "<img src..."; I do not have access to change the content server side.

How can I calculate the rendered height of an HTML table, from within JavaScript?

When the window is resized, I need to know how big the table is, so I can dynamically fit everything else nicely in-between. The table height is solely dependant on the contents, which are loaded dynamically. How do you calculate the rendered height of the table in JavaScript? ...

Rails equivalent of respond_to |format| with a straight render

I'm working with ActiveResource a lot so my service models are only using XML. Thus, I have no need for a respond_to block, I literally just render :xml => @model I can't however figure out how to render a 404 header using this. I've had to resort to respond_to, which I think adds a few unnecessary method calls. Here's what I'm using...

How do you make a CSS-defined table-cell scroll?

I want to be able to set the height of the table, and force the cells to scroll individually if they are larger than the table. Consider the following code: (see it in action here) <div style="display: table; position: absolute; width: 25%; height: 80%; min-height: 80%; max-height: 80%; left: 0%; top: 10%; right: 75%; bottom:...
