Re: .NET Security Anonymous25-Jul-02 6:48 Anonymous 25-Jul-02 6:48  I run the program as either myself or the administrator and still receive the same error. I do have permission, and can edit the registry successfully. The program is a sample which I obtained from Microsoft's web site. when I run the application, when I run the program in the browser I get the following error: Description: The application attempted to perform an operation not allowed by the security policy. To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file. Security Exception: System.Security.SecurityException: Requested registry access is not allowed: Source Error: Line x: mEventLog.WriteEntry(Message, EventLogEntryType.Error ........ Re: .NET Security jparsons25-Jul-02 8:24 jparsons 25-Jul-02 8:24  Go into your ControlPanel->Administrative Tool->.NET Framework Configuration. I haven't played around with this a lot but from there you can change the access rights of assemblies. One of those options should allow you to access the Registry.

I have requirement where I need to pass parameters to a crystal report using c#. Some how I am able to connect to crystal report and generate the report. Can any one help me in this regard. I have searched all the tech sites but of no use all deal with vb.net. So any help in this regard is very helpful asap. DirectX and .Net Firoz21-Jul-02 22:45 Firoz 21-Jul-02 22:45  Hi, How can I use DirectX objects in a .Net Application (vb or C#). Thanks, Firoz Re: DirectX and .Net jparsons22-Jul-02 5:42 jparsons 22-Jul-02 5:42  If you can access them through COM then yes Jared jparsons@jparsons.org www.prism.gatech.edu/~gte477n Re: DirectX and .Net sultan_of_6string22-Jul-02 8:12 sultan_of_6string 22-Jul-02 8:12  I strongly recommend you don't even try. COM Marshalling is really slow. You're best off creating a Managed C++ class library that contains native DirectX code. Still, there are some features such as Direct3D FVFs that are impossible to implement as managed code. Re: DirectX and .Net Andy Smith22-Jul-02 8:52 Andy Smith 22-Jul-02 8:52  for right now, you'll have to use Interop to talk to DX8. however, DX9 will come with a full managed api as well as the old com interface. so if you can afford the time... i'd suggest you wait on the dx9 release. Re: DirectX and .Net Domenic Denicola25-Jul-02 17:57 Domenic Denicola 25-Jul-02 17:57  When oh when oh when will it come out? I also am waiting on DX9 to begin my game development. -Domenic Denicola- [CPUA 0x1337] MadHamster Creations "I was born human.

Oh what fun to Install Wolfram Steinke21-Jul-02 0:38 Wolfram Steinke 21-Jul-02 0:38  Did a brain transplant on my Laptop with XP pro. Then to install Visual Studio .NET. Well it tell me I can't until I install the missing windows components. "would I like to?" it asks. Of course I would. So it does. Now at last I can install Visual Studio !!! At least that's what I thought. Now it tells me that I can't until I remove the Visual Studio component that is already there. Hang on!!! Wasn't I just advised to install it? Ok so I remove it. Restart the install program and guess what?? I can't install until I add the component I just removed. To paraphrase a TV ad that is running in Australia "NOT HAPPY!! BILL" Happy programming!! Mobile Device Application laphijia19-Jul-02 16:08 laphijia 19-Jul-02 16:08  I am just starting out with .NET I find it's great the ease it lets you create n-Tier applications. I just put up an SQL Server Db, I made an XML Web Service, and for the client side I already have a Web Application in C# or a Windows Forms in C#. You just learn to use the Add Web Reference: Smooth as silk! I was wondering now how the philosophy of Microsoft comes to play now. I mean, what if I want to create a client on JAVA2ME? or for the Symbian OS? Or for the Palm OS? or on the Pocket PC? or on the Smartphone? or on Linux? Technically it should be easy: you add a Web Reference, call the method "GetDataFromDb();" on the Web Service, retrive the XML file, process it, update! But what practically? Are there tools now? Is XML supported? Are web references supported? Oh I hope sombody thought about it! "Nelle cose del mondo non e' il sapere ma il volere che puo'." VBA.NET SHaroz19-Jul-02 7:29 SHaroz 19-Jul-02 7:29  Check this article out: http://www.fawcette.com/vsm/2002_08/magazine/departments/guestop/ It talks about possibly porting VBA to .NET. If they can do that, it seems feasible that the same could be done for VB6. Not having to learn a new language before switching to the .NET platform could probably greatly ease the transition for many people. While VB.NET isn't THAT different, it was somewhat annoying for me to get used to the language and the .NET platform at the same time. Companies that program in VB6 would probably switch to .NET a lot quicker if they didn't have to retrain a bunch of employees. Anyone else have any thoughts? Re: VBA.NET Kevin McFarlane21-Jul-02 5:45 Kevin McFarlane 21-Jul-02 5:45  If they can port VBA to .NET then they wouldn't have needed to change VB6 to VB .NET. Kevin to C.NET or not to C.NET Donald Blachly16-Jul-02 13:07 Donald Blachly 16-Jul-02 13:07  I have a pretty good grasp of C++ but very little success in GUI applications with MFC from MS Visual C++. I am interested in windows based applications (to be used mainly by myself) in engineering problem solving. Where should I begin? Should I concentrate on learning MFC from VC++ 6.0 or switch to .NET framework now? What books or training would you recommend? When you come to a fork in the road, take it! Y.

However, you're going to need to get your hands on some version of Visual Studio .NET, which is rather expensive In general I find the Wrox Press Beginning ___ (in this case Beginning C#) very good introductions, but since your a programmer already I've heard good things about Inside C# 2. -Domenic Denicola- [CPUA 0x1337] MadHamster Creations "I was born human.

So do recommend C#.NET over C++.NET? Why is that? When you come to a fork in the road, take it! Y. Berra Re: to C.NET or not to C.NET James T. Johnson17-Jul-02 20:06 James T.

I do; because I think its much easier to learn how to use the class library without the language syntax getting in the way. To me, the C# syntax is intuitive to the use of the .NET classes. My opinion anyway James "Java is free - and worth every penny." - Christian Graus Re: to C.NET or not to C.NET jparsons18-Jul-02 4:03 jparsons 18-Jul-02 4:03  This is purely my opinion but if you're going to use C++.NET then you should either use C# or C++. C++ wasn't designed to be run in .NET and as such there are some places where working with C++.NET is funny to say the least(boxing for instance). C# was designed to run in .NET. Essentially, anything you can do in C++.NET can be done in C#. C# has a much more intuitive syntax and once again IMHO is easier to work with sometimes. However this is purely an opinion thing Jared jparsons@jparsons.org www.prism.gatech.edu/~gte477n Re: to C.NET or not to C.NET Domenic Denicola18-Jul-02 7:07 Domenic Denicola 18-Jul-02 7:07  I recommended C# (BTW, they're technically called C# and Managed C++, not C#.NET and C++.NET). Basically C++ is not designed for .NET. The syntax is ugly and evil, and many things are inconvenient. It is good for mixing of unmanaged and managed stuff (read: non-.NET and .NET stuff), because with it you can write both. But otherwise, C# is designed for .NET and is a lot cooler as such. -Domenic Denicola- [CPUA 0x1337] MadHamster Creations "I was born human.

Re: to C.NET or not to C.NET sultan_of_6string22-Jul-02 8:20 sultan_of_6string 22-Jul-02 8:20  Quite frankly, it doesn't matter what language you choose (VB.NET C# or MC++) because they all work the same framework and 99% of what they can do is the same. MC++ is the most powerful and most flexible, but can be the biggest pain, as you don't have a GUI interface for designing forms/windows. C# and VB.NET are practically identical, except that C# can work with pointers (which I've never had a use for). If you're really performance oriented, create the front-end in C#/VB.NET and the back-end in MC++, as the C#/VB compilers suck. Re: to C.NET or not to C.NET jparsons22-Jul-02 9:04 jparsons 22-Jul-02 9:04  Considering how they both run under the CLR I don't see how MC++ could be significantly faster than C#. Do you have some benchmarks?

I found that out with ildasm, and I think there is an article on MSDN about performance tuning .NET which admits the same thing.

I realized however that on the CD it says, "Microsoft Visual J#.Net Standard." What does standard mean? Is there an enterprise version? If so, that is what I should get considdering that I have the enterprise developer edition of VS.NET. Is this yet another plot by Microsoft to screw with my head? Re: J# standard? Kevin McFarlane21-Jul-02 5:26 Kevin McFarlane 21-Jul-02 5:26  It's probably just mirroring J++ 6. If I recall, there was only ever a J++ Standard Edition with VS6. At least that's what I received in the post after purchasing an early version of VS6 Pro. If that's so it is, of course, very confusing, as VC++ Pro, etc., aren't the same as the Standard editions. Kevin Linked List? yaaang15-Jul-02 14:22 yaaang 15-Jul-02 14:22  Is there a linked list class anywhere in the Framework? So far, the closest classes I've seen are the ArrayList and the DataTable. Also, is the DataTable like the ArrayList in its need to shift its elements over when inserting a row at a certain position? What? Were you expecting something witty or funny here?
