• Visual C# .NET and .NET API from OPC Foundation

  I hope that's the right forum for my question. I have to communicate via .NET API from the OPC Foundation with a Siemens OPC Server to get and set data. I want to use OPCDA and C#. Unfortunatly the documentation is poor, I didn't find useful samples or better description. For example I do not know how to get to a server object. I find no documentation about what exactly is url.Path, what for do I need connectData Opc. Factory f = new Opc. Factory ( typeof (Opc.Da. Server ), true ); Opc. URL url = new Opc. URL (); url.Scheme = Opc. UrlScheme .DA; url.HostName = "ATHEAUGW0476" ; url.Path = "OPCDaten" ; f.CreateInstance(url, null ); Does any one know a ressource to get samples, documentation or any h ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Problems on resize

  Hi, I’m the coordinator of Jad Engine, a MDX 1.1 open source 3d engine. We have had one bug around for several months that we are unable to solve related to resizing the device. At the start, we used SetAutoDepthStencil = true when creating the device, and there was nor problems with the resize. But nowadays we do it manually and SetAutoDepthStencil is false. But when we reset the device, the D3D debug tells us that one surface has not being liberated. That surface is the DepthStencil we just created, because if we don’t create it, the reset works. The Microsoft.DirectX.Direct3D.Device.IsUsingEventHandlers is set to false as we create ourselves the VertexBuffers in DEFAULT mode and that’s the only way that they don’t give us an error on th ...Show All

• Visual C++ trouble with __declspec(dllimport)

  NOTE: I'm using VS 2005 I am attempting to access a driver using __declspec(dllimport) (as the .h file that came with the device was setup this way), I've never done it this way before so I'm experiencing issues. (I am doing this on a handheld but I feel this is generic enough for the general forum) (I don't think it matters but this is a ZigBee SDIO card from C-Guys) I've placed the .dll file and the .lib file (don't know which I actually need) in the project directory (with all .h and .cpp files), here are some bits and pieces of code from the .h file #define SDZIGBEEDLL_API __declspec(dllimport) . . .

• Game Technologies: DirectX, XNA, XACT, etc. Applying shaders to DX7 scene -- any way?

  Is there any way to render shaders onto Direct3d 7 objects I realize shaders weren't introduced until DX8. However, I'm stuck with a proprietary DX7 game engine and I cannot access the source. One possible hack would be to render the DX7 scene to a bitmap, apply that bitmap to a DX9 object, apply a shader to it, then bring that bitmap back into the DX7 scene. But I've the feeling that won't achieve the desired shader effect. Is this a viable option, or are there any other options for applying shaders on DX7 objects This is not achievable in real-time frame rates. Transferring data from a DDraw7 surface to a D3D9 surface is going to be very slow because it has to be all done on the CPU by locking both surfaces manually and doing the ...Show All

• .NET Development Running Windows app on Thin client doesn't work

  Hi, I have created my first Windows forms app in .Net 2.0; installed it on a thin client (not sure which version of the Windows OS it is running); when I double-click on the exe file to run it, the hourglass comes on briefly, then goes off and nothing else happens. If I run the app on the C: drive of a thick client (running Windows XP) it works OK. The app is a Windows forms/ Crystal Reports app; using a Microsoft Access database. Any idea on why nothing happens when I run it on a thin client and how to resolve it Thanks in advance. AndrewVos wrote: I think he/she means an embedded OS Like on a cellphone or something...

• .NET Development Expose DataSet for web service client

  Hi: I have a web service with a typed dataset defined. I also got a windows form as a web client to consume the web service. In the win form project I successfully added a web reference to the web service but was not able to reference the typed dataset defined in that web service. I took a look at the Issuevision sample and confirmed that the client was able to reference the typed dataset referenced in the web service. So I'm missing something here hope that someone can give me a hint. Both solutions were developed in the VS 2005. Much appreciated. Hi Rod: Yes, I got the referenced Dataset once have a return method returned to it. As it is my first time writing web service this certainly is one o ...Show All
