Perhaps [url=http://ubicomp.algoritmi.uminho.pt/local/concavehull.htmlis]this site[/url] something to consider.

Hi, Why do I only see appearing a red rectangle after 1 sec with the following code, and not a blue one and after a sec a red. Just used a new forms app with a panel control added and the following code: [CODE=c#]using System.Drawing; using System.Threading; using System.Windows.Forms; namespace …

Would not say the 70s were mis-spent, they were colorful indeed!

Hello everyone! I know how to use a Timer class: [CODE=C#]static void Main(string[] args) { System.Timers.Timer MyTimer = new System.Timers.Timer(); MyTimer.Elapsed += new System.Timers.ElapsedEventHandler(MyTimer_Elapsed); MyTimer.Interval = 2000; MyTimer.Enabled = true; //etc. } static void MyTimer_Elapsed(object sender, System.Timers.ElapsedEventArgs e) { //do something every 2 seconds }[/CODE] What I like to do …

You must not use base.OnKeyPress(e); in your override. By doing so, you will first execute what is already programmed in the base class, which is a behaviour you don't want.

Hi Serban, welcome here. Did you read the excellent explanation of Rashakil Fol to it's full extend? The handy syntax [B]public double X { get; set; }[/B] can only be used if you have version 3.x of C#. My guess is you use a lower version. If that is not …

I'm not an native English speaker, but i have heard words like [B]sign in, sign on [/B]to enter something, or [B]sign off, sign out [/B]to leave. But I think these phrases are more used when a person has to sign a register, when entering a building.

I have some understanding of static versus non static. But your code looks rather strange, to say the least:-O ??? Just as a starter, what is [B]mainprogram [/B] supposed to mean?

If you don't want to, you don't have to close the Form if you still need it. Start with 2 forms and toggle between them with the Show and Hide methods.

Do you mean graphical design or software design?

Like this: [CODE=C#]public System.Drawing.Color ColorSaved1; ColorSaved1 = TextBox1.BackColor;[/CODE]

MessageBox is usefull, but no! You cannot put an image other than the ones provided into it. No problem: create a Form class to imitate the behaviour of the message box. Because it would be a class of your own design, you can do in it what you want;)

Hi Jonahmano! This can be done very easy. Instead of [B]WriteLine[/B], use [B]Write[/B]. WriteLine writes a string and put a extra carriage return character after, Write does not.

maybe you could have a look at [url=http://www.codeproject.com/KB/cs/USB_HID.aspx]this site [/url]

I think it has nothing to do with your programmings skills. For this method to work best yo have to have your initial guess, as close as possible to the real root, or the method may fail to converge. Readall about it in [url]http://en.wikipedia.org/wiki/Newton%27s_method[/url]

Has probably to do with international settings. In some countries the , (a comma) is the decimal sign in others it is . (a point)

Use the List Count method to know how many items are in your list, not some hard coded number.

This [url]http://www.functionx.com/csharp/index.htm[/url] is a starter. If you browse the net you can find many more.

The PropertyGrid only allows one object at the time. Perhaps you could implement the ContextMenuStrip of the PropertyGrid. By right clicking the PropertyGrid you could then select between different objects.

You must not hate something. Java is not my cup of tea also, but it is not SO bad I hate it. You could design a library of DB, file, graphical and other utilities, that might come in handy when you eventually start your professional career. With your academic degree, …

Don't know much about FIX but [url=http://en.wikipedia.org/wiki/FIX_protocol]this[/url] should be a good starting point.

Look up the series formula for the logarithm function and do the same as I showed you in the cosine thread.

The sign function returns 1 if the number is positive, 0 if it's zero and -1 if it is negative. You can implement that using the if statement.

This snippet [url]http://www.daniweb.com/code/snippet217265.html[/url] allows you to enter only one decimal point. It should be easy adaptable to what you want.

Read file, when you read POROSITY read "/" Then read all following chars until "/" into a string array. Don't know with what chars your doubles are separated, but if you know, use the string.Split method to separate all doubles in an array.

This code works perfectly with me: [CODE=c#]namespace WindowsFormsApplication1 { public partial class Form1 : Form { public Form1() { InitializeComponent(); textBox1.AppendText("("); textBox1.AppendText("÷"); textBox1.AppendText(")"); textBox1.AppendText("÷"); } } }[/CODE] You don't have to use the Focus method, the textbox still has the focus.

If you are using Visual Studio C# Pro or Express, it is implemented automatically. You don't have to implement it yourself. Unless of course you did something with the MinimumSize or MaximumSize properties of the Form, or you set the MaximizeBox property to false.

What have you got so far? Your question is a little vague.

I have [url=http://www.andzelika.co.uk/TCPsockets.pdf]this book[/url] at home maybe it helps.

You are calling [B]new Random() [/B]so close after each other you will get the same random sequence every time. Try to use it once and than call the[B] Next() [/B]method. Or better still follow the advice of sknake!

Don't know exactly what you mean with base classes. C# has no functions, it has methods and properties. Example: in C/C++ you can use the function [B]strlen[/B]. You feed it [B]MyStr [/B]and it will return you the length of [B]MyStr[/B]. In C# you simply say [B]MyStr.Length[/B] Length being a property …

Perhaps I don't understand you very well, but the spacebar, albeit a bit greater than the other keys, is a key like any other key.

Scott, I wonder how you do it, to come up every time with these little crystal clear snippet gems! :)

Is it possible to add a sort of readonly "newsflash" item to the community center? To communicate and explain new features, make anouncements etc.

See the similar thread [url]http://www.daniweb.com/forums/thread228060.html[/url]

Every FlowLayoutPanel has a Controls collection, us it like this: [CODE=c#]if(panel1.Controls.Contains(MyPict)) { panel1.Controls.Remove(MyPict); }[/CODE]

Use [B]if-else [/B]if or [B]switch- case [/B]constructs to check for the right chars. This also seems something that can perfectly be handled by a Regex.

Start a new Forms application. Drop a Panel and a Timer control on it. Set up a Timer_Tick, Form_Load and a Panel_Paint eventhandler and fill in the code. Run the app and watch the string rotate.

>>for example if you are mark I'm not an English speaking person myself, so I have great problems in understanding what you mean by the word [B]mark[/B] :icon_eek:

Use a Stack or a Queu. What have you made for yourself so far?

I added the tag C#. Seems to pose no problems.

What do you mean with window? A window from another application or a forms window in your application?

I often have the same experience. I have a question, but when formulating it, I find the answer!

If you are using Visual Studio you can edit the tab order of the controls. The TextBox with the lowest tab order will recieve the focus. Select tab order editing in the View menu.

Very well done!

When you open a window, eg. Documents you mostly see a bunch of icons you can select. You can drag a selection rectangle over some files. You can select more files by holding down the ctrl button and drag another selection rectangle etc. This way you can select file icons …

Use [CODE=C#]for (int i = 0; i < n; i++) { dataGridview.Rows.Add(); }[/CODE] to add n rows to your DataGridView

Ben E. King wrote the original, John Lennon made beautifull cover of it. vmanes this is... well I am speechless... All the world together, I weeped...

Never did this but you could declare a List of List : [B]List<List<string>> dim2 = new List<List<string>>();[/B]

You can use enum but perhaps in this way: [CODE=c#]public enum Output { _0 = 1, _1 = 2, _2 = 4, _3 = 8, _4 = 16, _5 = 32, .... }[/CODE] This way you can set port 1 and 2 on like this ; SetIt = _1 + …
