Greetings,

I need to plot a 3D chart using 3 axis – x, y, and z. It is done in C# .NET environment. Was trying to enclose a mockup for illustration purposes without succes to this message, would be seny by mail if needed.

I have been trying to use MsChart. I manage to render a 2D chart (x,y axis) but I am unable to render 3D with three axis. If you know of a way to control the data point’s color that would be of much needed help too, although it is secondary to the rendering challenge.

I would appreciate your assistance in pointing me to resources, references, or post the correct code to render a 3D graph.

Many thanks,

Amir.

There is definitely at least one free charting library that does 3D, but you'd have to google, I don't have the name.

Databound controls and best practices

What is the current feeling about the use of databound controls? When I first started using a RAD framework I remember many people on the message boards that I belonged to were very much against the use of databound controls.

IMO they greatly speed up development - but are they considered a good practice in the industry?

I can't imagine why anyone would be against a data bound control. What was the reasoning ?

I think what he means is the early binding learnt by most newbies from the MS tutorials which I think stink. OTOH manually populating controls is just stupid.

My apologies, my memories of the arguments are poor. This was back in the day when I was using Borland Builder. I seem to recall that many of the people on their news groups thought that the use of databound was evil. I even worked for a man who used Delphi who refused to allow his staff to use databound controls. I have always used them, because IMO, it is part of the point of using a RAD tool - and I am using them heavily now. But I was curious what the industry's view is.

I am setting the data source of a combo box in the form constructor. the problem is that when the page is loaded and the data is being loaded in a combo box the selectedindexchanged event is being triggered. i don't want that to happen. how can I tackle that problem please?

Thanks for the help

A common problem. You can either set an internal flag that tells whether the combo is being loaded during initialization or disable the events and reenable them after the combo has been loaded.

I am using a flag but the problem is that the selected value remains the same even though I change the selection. how can I solve that please?

What do you mean, "the selected value remains the same even though I change the selection"?

You're original question was how to work around the event firing during initialization. Now, however, it seems the problem is something else. If you want help around here state the problem clearly. Read the first post, How to get an answer to your question.

Subscribe to the SelectedIndexChanged event after the page load?

Creating a Console in a WinForms Application

Hello. I'm im in the process of creating an IRC Bot. I want to have one window that has a GUI with buttons and the other to be a console window where all the output will be displayed. I was wondering if it is possible to use Console.WriteLine in a WinForms application and if so, how would I go about that? Thank you!

You can't use Console.Write but then again you don't have to. A TextBox, or ListBox even, properly formatted will look just the same.

Console.Write/WriteLine writes to the Debug Output window. I don't know if it's possible to redirect this.

Console.Write writes to StdOut, which in the Visual Studio IDE is the debug window. In a console app, its the console window. You can mess around with setting the stdout but why bother when there are other methods available in a WinForms app.

Hi,
Create a standard winforms project and then go to the project properties and change the output type to console. Magic, you'll have a console and a form.
