I'm a newbie to Direct3D technology. And was trying out D3D shared surface code found at Direct3D10, 11 and D2D in WPF - Round 2 DEMO! by Jeremiah morrill Interop.D3DImage.rename2zp. I was able to compile the code without any issues but when I run it I see a blank screen Output window
I'm using VS2013, DirectX SDK(June 2010) and windows 7 OS.
D3D is often pretty good at telling you what the problem is. If you go into the project properties, and enable native debugging, you might see messages in the output window which which will give you a clue - as long as you're running the debug version of the app of course.
There are many reasons it might be failing though - it could be that your graphics card doesn't support what the demo is doing, or that it's starting up with the wrong device settings.

I have a hobby website:
http://www.chartmygolf.com/Programs/Program.aspx
and for the first time (in six years) someone has said the circle/percentage thing that appears when the program is loading is not appearing, and consequently the program does not load. What could be causing this?
He has installed Silverlight 5.
He is in the USA so I have a bit of time to prepare some ideas. The things I have thought of so far are:
A 32/64 bit mismatch between Internet Explorer and Silverlight versions. If it is this how do I check what 32bbit or 64bit versions they have of each?
Whether they have Silverlight not Enabled in Internet Explorer. (I think this might be low odds because he tried to load it on firefox and chrome with the exactly the same problem).
Does anyone know another Silverlight website page which requires program loading, so I can check if the problem he is having is specific to my page or to Silverlight programs in general?

EDIT:
Some more info.
He is operating on Windows 7.
He went to the sample Silverlight page (Silverlight SDK Sample Browser) and it loaded most of the way. What doesn't load is the top section and the sidebar which both have spinning circles around them with 100% in the middle.
He is using IE11.
In the add-on section the Silverlight is enabled for both 32-bit and 64-bit versions.
I hope this can be resolved.
I'm running my SL5 application (that has been working well so far) on Windows 8, and it is not going well. I have a background picture which usually does not render correctly, almost everytime I navigate my background (including the controls over it) just goes white till I resize IE, then it re-paints (what makes it stranger is that the parts that goes white is outside of the navigation frame, why is it getting repainted). (Chrome renders fine)
When I run my application out-of-browser my login screen pops up and works correctly but after the login screen closes it looks like the gray background of the login screen remains behind and I cannot click on anything, resizing makes no difference, it looks like every control has been disabled.
I have updated my NVidia Drivers to the latest, don't think its a display driver issue though.
Anyone else had these issues? Anyone else running SL5 fine on windows 8?
(Looks like I'll be downgrading back to windows 7 soon)
Silverlight should run great on any desktop browser in Windows 8, just like it does on Windows 7, Vista, and Mac. The underlying runtime is 100% the same. That does not mean you may not find a glitch with a graphics driver, but it means you shouldn't - and likely won't.
I did want to make a clarifying point, however, that Silverlight is not part of the Modern Internet Explorer (the Metro Internet Explorer). Only a subset of Flash is supported and that is only supported on white-listed sites.
This means Silverlight solutions that you might have expected to run on the Surface RT (running Windows RT - or Windows on Arm) will not run (as there is no SL runtime). And, I think we can all have a collective moan and ask, together, "Why not?" To which there is no acceptable answer.
The theoretical goal, of course, is to write native Windows 8 apps. If you want to write something web based you should write it in HTML5. That's the official word. I think we all know that HTML5 has a ways to go in order to catch Silverlight, but it is what it is. Can't change some things.
I have had no issues with any of my Silverlight 5 apps running on Windows 8 - I focus mainly on line of business apps but have some graphical and otherwise apps that run fine as well.
I'm only marking this as the answer to close the case, what the actual answer was to the problem we will never know. The solution: automatic updates. After much hassles with getting automatic updates to actually go through, my machine is now working well.
I'm having a problem with a trusted Silverlight 4 OOB app when it runs on a Mac.
In order to debug I'd really like to be able to capture the debug/trace information output by the app. (The problem is in in code running in a background thread so outputting debug information to the screen isn't practical and risks creating new issues.)
Ideally I'm looking for the Mac equivalent of DebugView, if there is one.
If not, any tips on other approaches to debugging htis will be greatly appreciated.
In the past I have created a com visible dll in c# that simply uses the standard win32 outputdebugstring call to output debug info. This can then be called from within Silverlight using COM automation :-)
Visual Studio 2010 moved to using WPF for rendering the editor. This is leading to slowdowns while I am editing code, especially if I'm running something else that uses other video capabilities.
How can I speed this up? A new video card? New drivers? Settings?
What technologies does WPF use to render and what video card would complement it?
WPF uses DirectX for rendering, so a new top of the line video card would certainly help you out here. Any solid ATI or Nvidia card nowadays supports the latest and greatest DirectX.
The answer from #Charlie is absolutely spot on; and I thought about saying this on a comment but then figured I should put it as an answer.
Under certain circumstances (certainly on my desktop at work, which uses a workstation NVidia card), which are listed in the installation issues (connected with Hyper-V in particular), VS2010 fails to enable video acceleration even if it is available.
Open up Tools->Options, and on the very first options panel you'll see a group in the middle 'Visual Experience'. Just make sure that everything is checked in there and that it says 'Visual Studio is currently using hardware-accelerated rendering...'.
I don't think the hardware requirements for VS2010 are particularly heavy - but your card certainly must be DX capable.
I need to develop a part of a business application in a flashy eye candy way. Therefore wanted to see if I can use DirectX. Here's what I got.
First I read how using C/C++ is like shooting yourself on the foot and I should use DirectX.NET instead. I couldn't disagree. It's the 21st century.
Downloaded DirectX SDK but couldn't find the .NET assemblies in there. Searching the net now revealed that DirectX .NET (called MDX) is now obsolete (released in 2006). And that I should use XNA instead which was mainly developed for XBOX.
Downloaded XNA. But it won’t install because I don't have C#.NET Express 2005 SP1. Installed SP1 on my VS Pro 2005. But it won’t install still. It needs Express 2005 and exactly that single one version, not Pro, clearly not 2008.
Frustrated tried to download C#.NET Express which is free. But the link from MS which says C#.2005 actually downloads C#.2008, because C#.2005 is now obsolete.
And now I read that MS is now putting it's force behind WPF/silverlight. And XNA doesn't support DX10 and Vista doesn't come with DX9.
Now I have two choices:
Go 15 years back and code in plain old C/C++. At least C has proven itself to be timeless.
Try silverlight.
What would be your advice? Or am I missing something?
Udpate: Would like to add that DX10 is not backward compatible with any other DX version. SlimeDX looks really promissing. But as a very new package, I am not sure how much helpful the documentation and tutorials will be.
Udpate 2: It seems that the first download link that google brings up when searching for XNA download, which I used, is not the latest one. Thanks DouglasH for providing the link to v.3. Downloaing it. Probably it will work.
But then agian. Should I switch to WPF/Silverlight? Or go with XNA? Which one is better documented and future-profe?
More update: Vista realy doesn't come with DirectX 9 preinstalled [check by googling]. At least it didn't on my machine bnough last year. Googling for it revealed that I have to manually install DirectX 9 on Vista after downloading it from MS. But my attemet failed beucase hardware drivers for DX9/vista were missing or didn't work. I got the idea that it's not supported that well.
MS has stopped supporting the .net DirectX libraries. There is an open source alternative called SlimDX, and it works well. The documentation leaves some to be desired, but it can be puzzled together by using the DirectX C++ documentation and some common sense.
WPF does pretty good 3D stuff, and there are lot of fish eye panels and source code available for WPF, yes since MS has gone ways from their technology, in today's terms, we can not focus on only one technology by MS to make entire one business application.
Sure we are also tired of using multiple different versions of technologies even to do smallest parts, but I believe they are doing great job by serving billion machines, it sure isnt easy but WPF and .NET seem to be most stable technologies by microsoft and also they are spending good money on making completely managed operating system as well.
If you ever go back to C or C++, you might want to check out Simple DirectMedia Layer (SDL).
IMHO, it is much easier than DirectX.

DirectX is fully backwards-compatible. Any DX9 application will run on Vista and DX10. As for XNA and VS2005 - that's a bit weird. That would make XNA effectively useless. Check if you haven't missed something.
couple of points, which version of XNA did you download. Here is the link for XNA Studio 3.0 which will run on Visual Studio 2008. http://www.microsoft.com/downloads/details.aspx?FamilyId=7D70D6ED-1EDD-4852-9883-9A33C0AD8FEE&displaylang=en
2nd, I sure hope that Vista has Direct X 9, since that is the version of direct X that the DWM runs on in Vista. I think you will find the DLLs for Direct X 9 and before and the DLL,s for DirectX 10 loaded in Vista. Or for that Matter Windows 7 which will also have directX 11 (edit 2 note that the DWM is built on DirectX10, with a software emulator for systems that don't have 3d video hardware, a dx10ondx9 drivers for those with directx 9 cards and of course full support for directx 10 cards).
edit,
Additionally if you downloaded the March directx sdk, you download, directx 9.0c, directx 10, 10.1 and the beta of directX 11. and I would have to check if DirectX 8.x is still included or not although DirectX 9 is backwards compatible with most of that platform.
Though I never worked directly with DirectX (little bit with OpenGL) - I would take WPF. The least-painful to implement (transparency, gradients, brushes, animations, etc.) and it provides solid-performance from what I have seen and experienced myself.
But yes, it's not platform-independent.
