im getting some error while comiling the code in Article III (DirectX II):
Im using VS.NEt 2004 and i have .NET Framework 1.1 redistrutable installed.
The eroor i get is this...
An unhandled exception of type 'Microsoft.DirectX.Direct3D.InvalidCallException' occurred in system.windows.forms.dll

Framerate Issues - using Radeon 9550 (bottom end DX9  card)

Strangely, my DX apps run at 49 to 72 fps, and i cant tell what makes them run at these rates. But this is clearly nowhere near possible, upward of 700 fps for a simple scene. Looking in Control Panel > Direct X, i see that i've selected 'Use retail version of direct 3D', instead of 'Use Debug version of direct 3D'. So why no speed ? Also, i can compile the microsoft sample directX empty project and it runs at 760 fps.

PS. When's part IV coming online, i think we're ready for it.

I get the following exception: Microsoft.DirectX.Direct3D.InvalidDeviceException on the following line of code in the constructor:

Caps caps = Manager.GetDeviceCaps ( adapterOrdinal, DeviceType.Hardware );

when I connect my laptop to the docking station with an external monitor.  How would I insure that this is going to work under conditions like these?

I am having no trouble with Dot Net 2003 and this code.  There have been a few tasks where I had to address the issue in a slightly different manner.  I did not copy the code from the samples, but typed it in instead.  Maybe there is a difference.

Is there any coming DirectX III article? 'Cause this episode seems dead....

I've been working through this series to get my feet wet with VS2005, and it's been fun.

A word of warning.  Direct3D is not supported by the video card used by Virtual PC / Virtual Server.  So, your app will compile, but you can't run it unless you can get the 2.0 beta runtime on an actual hardware system.

Thanks Derek, this intro has been great so far.  I can't wait for the next article.

Greetings,

I am working on plain box that has all of my VS 2005 .NET 2.0 stuff on it.  I am using the mainboard graphics processor.  My box does not have a graphics card.

I got the same error on DeviceType.Hardware.

I changed to DeviceType.reference and the code woked.  At least past that line.  I am having other DX9 issues.

I am getting a runtime error on this line...

device.DrawUserPrimitives( PrimitiveType.LineStrip, 6, this.CreateCrossHairVertexArrayTop() );

I just starting writing this tutorial about 3 hours ago, so I am still tweaking.

Hi All,

   trying to do this in VB.Net, d/l the C4FBegDev3VB.msi file and installed it but when I load the source it's missing the
 Microsoft.Samples.DirectX.UtilityToolkit, Is there somewhere I can get this file in VB format? I have the dxmutmisc.cs file in the August 2005 update DirectXSDK folder.

      Thanks,

I resolved the problem, had to compile the DirectXSampleFramework that was in the part I code download and copy the dll into the bin folder for the VB code.

Hi All,

I am fairly new to DirectX programming and C# and I am having some trouble with the code in the second article.

I noticed that when running the Release code for the second article, entitled "Introduction to DirectX", I encounter an unhandled exception error, specifically D3DERR_INVALIDCALL.  It looks like the problem is in the Device constructor related to the PresentParam.Windowed enum.  When that is set to true (the app is running in windowed mode) it works just fine.  However when .Windowed is false (fullscreen mode), the exception occurs.  I am not sure how to fix this problem and was hoping someone could shed some light.  I'd really love to be able to Clear my screen to a dark blue color .

Thanks in advance for the help.

I upgraded my on boad video drivers and am having much better performance on my machine.

For users who are getting 2-5 FPS make sure that any where the device is getting set up that the DeviceType is Hardware and not Reference.  Reference is really slow.

Now then, is anyone getting a really blurry/pixely skybox?  In part IV I used the MSFT lobby images and they are super clear, but when they render on the skybox mesh it is like everything is out of focus.

Is everyone having this issue?

I've noticed that the maximum framerate is tied directly to the monitor refresh rate, at least on my system.  Even if all I do is call the Present method, my frame rate ends up being 60.  However, if I cover the game window with another window, the frame rate moves up to it's theoretical maximum (as shown in the window title on the taskbar).

This means the Present method is "eating" any extra time between frames while waiting for the monitor to refresh.  Is there any way to get this time back for background housekeeping, like unloading defunct objects or preloading new stuff?

Or since housekeeping is necessary regardless of client speed, the "extra" time could be used to provide as much extra eye candy as can be rendered before the next render loop has to start...

I got some problems. Special with my directX. Im running win 2k, framework 1.1, Visual studio 2003. But i cant get a newer directX update with the samples and dll´s wich can run on my OS.
Do anybody know a version or what i am going to do ??

Tips
Add a height map so the terrain is not just flat - Realy you should
Cover simple animation

If anyone else knows how to do this in vb please contact me

Hello there,
      I am having the same problem as you (Exception thrown by the caps creation line). If you can help me in any way von thtis subject i would really appriciate it as i am very eager to move on with the tutorials.

Thanks Steve

Hey all,

Working my way through the examples, but got stopped in my tracks after the 2nd one!

After adding DirectXSupport, and the Microsoft.DirectX and Microsoft.DirectX.Direct3D references, try to compile and get 37 errors, all about the same...

"The type or namesapace name 'Filter' could not be found"...

I've re-done the project up to this step about 4x now with the same results...

DirectX version problem?  I'm doing this on WindowsXP but saw on sys requirements server (?)...not sure if that's a problem...

Anyhow, pretty burnt on trying to figger it...any help would be great!

BTW, am a VFP programmer, noodling around with C# Express...

Thanks!
