As it goes, I don't think an animal does move randomly around terrain. You'd find that an animal would head towards shelter when it's hot or raining, it would go towards water or food when thirsty or hungry.
It sounds like you are doing an A-Life simulation. Is this correct?
It's not random movement, but if you can get your hands on (any) of the Boids demo code in any of the Direct3D SDK versions from have implemented a pretty decent flocking algorithm. Baring that, you good probably do a search on the net for flocking algorithms. You'd probably find quite a bit.
Hope this helps.
Cheers

Hi,
I'm a newbie to C# programming and .NET framework.
Is there a programmatic way of accessing SOAP/HTTP messages transferred from C# client to a web server (on which the web service is hosted.
Please clarify.
Thanks,

Why no map modes (i.e. mm_ANISOTRIPIC) in .NET? Are you expected to interop back to the Win32 calls to set up the map mode?

Map modes are a GDI thing so the .NET equivalent is the stuff found in GDI+. In this case the Graphics object has a PageUnit and PageScale property as well as Transforms for doing more complicated things.
If you have Petzold's Programming Windows with C#, chapter 7 of his book is the chapter to look for regarding that.

Thanks. My problem is that I have to take display data generated by an Visual C++ ActiveX control using a mm_Anisotropic transformation and display that same data in exactly the same way in a .Net Windows form control.

No. The entire point of the project is to get rid of the activex control altogether.

Hi.
Is it possible to chage the ForeColor in a ReadOnly TextBox? I haven't succeeded. If I set ReadOnly=false it works, but otherwise the text just comes out in black.

Hi again.
Using RichTextBox in stread of an ordinary TextBox seems to solve this but if I want to print out different parts of the text in different color and font style -how can I do that? For example I would like to write mark certain lines of text to draw attention to them.
Regards

You have .SelectionColor and .SelectionFont to change things under current selection (and of course you can program selections as well). Check out the "simplepad" sample from the .NET framework SDK.

Does anyone out there know how (if possible) to write an automation model for an application in .NET. The application in written in Visual C++ with MFC. I want to be able to drive the application in the same way as one van drive the office products. At the moment we only have a COM automation model.

automation is now legacy. You still think about COM and automation when a raw (unmanaged) C++ app is going to execute commands on an automation server.
But that's not how you do things with .NET, as long as both client and servers are written using .NET :
- on the server side, you write an assembly project using whatver .NET language.
- on the client side, referencing assemblies is the equivalent of including the header files, iid and clsid declaration. Then doing a new Word.Application() is like doing a C++ CoCreateInstance("..."). etc.
And if you are intending to expose a .NET assembly to a raw (unmanaged) C++ application, then you'll have to use [ComImport] attributes in your .NET code, and use the tlbexport.exe tool (or regasm.exe which both creates a type-library and registers it).
Good luck!

Does one need adminstrator rights to install the .NET framework?
Also, does the use of .NET controls in IE requires administrative rights?

First question answer is yes. dotnetfx redist[^]

For question 2, this depends on what you exactly mean by ".NET controls in IE".
Regarding the official issue with .NET 1.0[^], one cannot expect much without full control (which is a shame by the way).
I believe as a general rule that administrative rights, and low-security IE level is required. After all, .NET controls in IE are activeX bridges.

Second again, thanks for the response and the information.
Actually, I am expecting the same effect. However, a customer is claiming otherwise, so I needed to confirm this since I have not actually started using .NET custom controls in IE yet.
We ship ActiveX GIS engine to this customer, they use it to create Active Document for an intranet application for a big company and this is installed on a server. Individuals are to download the files and install. But they are not supposed to exercise admin rights on their machines - personally hoping administrative handling of MSI could handle the problem.
We wanted to configure the ActiveX GIS to allow non-admin registration, but the customer claims .NET is the way to solve their problem 
With no active document in .NET, they are most likely going to create .NET custom/user control to be used in the IE. Hoping this will solve their problem, we are under pressure to give them a .NET version
I, therefore, have no choice but to arm myself with more information 
Best regards,
Paul.

You can programmatically request for temporary local admin rights. Discuss it with the MIS in your company.

Thanks, but have you read it? I could not help myself after reading the summary:
In the past, Web developers often used ActiveX controls if they
wanted customized client-side functionality incorporated into
their Web applications. Now, they can build objects supported by
the Microsoft .NET Framework which are more compact, lightweight,
secure, and seamlessly integrated.
Best regards,
Paul.

Read it thoroughly Paul. There is everything you need there.
In summary,
- the client must download the .NET run-time, and install the .NET run-time
- he must use the .NET framework control panel to ensure that .NET controls hosted in IE (with IEHost.exe) will work
- to ease end user configuration and approval, in much the same way than with standard ActiveX, you'd better sign them : create a .snk file (public key).
- of course, if your component does a certain r/w access on the filesystem, your component may require the end user to further slide down the IE security level.
I guess what would be fine for you is .NET controls running on the server-side, while being displayed on the client-side. I am not sure about whether it is possible. However I am pretty sure that you'll probably need in the ideal case a deep ASP.NET integration.
Have you tried MS KB and product support ?

Yes. It is a well written article. Just the part "compact, lightweight" in the summary makes it interesting

I have done much work with .NET controls in a prototype product here, but 1% on ASP.NET so far - mainly playing with simple samples. I will be looking into this possibility too. Also, the server-side control running on the client will be a great idea - will search more on this.

The last time I tried MS product support was with MS Fortran PowerStation 4.0 - guess the year! student days
In our company, there is one in charge of this, I will discuss these points with him. I tried the KB and could not get far, may be my search strings were not informative enough. I have being using the MS product newsgroups on .NET related issues to find some way out.
Thanks for your support too.

How do I create a "latest news article" viewer, which are very common. The CodeProject home page has one on the right side. I need it to basically show the last X articles, read from the database of course. It should show the first Y characters of the article. Thanks in advance.

Basically you just need to post an http query (WebRequest)and get the HTML response (WebResponse.GetResponseStream()) from it. That's what this[^]CP article does.
You usually have a text file, or xml file, listing all URLs, such like in here (web resource provider)[^].
Because it is HTML, you may have to strip all the formatting, such like in here (html parser)[^].
if you start putting in too manay features, it no longer remains useful for beginners

I guess my question is more basic. What control do I place on my ASP.NET web form page?
|
|
|
|

I don't know. Try the "Web development" forum. Or Asp.NET[^]
