Hi,
I have some advanced knowledge of programming with C and C++.
While I like C for its simplicity and speed, it lacks some important functionality (like OO). I'm not very fond of C++, since it is quite clumsy. (But you know all that already)
Anyway, I was looking for a new programming language for little projects. I looked into the specs of the D language and became quite fond of it. Anyway, I hear a lot of good things about C# as well.
I am not experienced enough to compare the two simply on the basis of their specifications. I tried finding some comparison on the internet but failed to find anything more recent than from 2003.
I was wondering about the advantages of either and languages, and in which case one is more appropriate than the other and I hope you can help me out!
Many thanks in advance,
Mike

C++ is awesome, sorry to disagree.
The main advantage of C# is that more than 5 people have heard of it, there's tons of support and there's actual real world jobs using it.

I was aware of this, but I was more interested in the technical side

At the end of the day, if you want performance, you want C++. However, realistically, the fact is that for most tasks, you won't notice the difference that C++ gives you. If you just want to program for fun, then the answer is, a forum dedicated to the D language is far more likely to contain people who have used C# than vice versa. Even then, I don't see it as likely that you'll have reasons to use D that are compelling enough to offset the lack of support.
If you have any intention of coding for a living, then you can't avoid the fact that C# is where the money is at ( unless there's a niche market for D that I'm not aware of ).

I looked at D a few years back, and as far as I'm concerned it's C++ with added sugar (and garbage collection). Neither language fixes all the shortcomings of C.
On the other hand, when considering C# it's not so much a question of the language itself, because C# targets the .net framework which, for me, far outweighs any particular language features and really invalidates any comparison.
I use C# regardless of the size of the project, though I still use C a little bit as well.

Hello, I have a multiple textboxes in a form.
I read in values from a textbox, and depending on what is read in, values are sent to certain textboxes. However I am not able to do this dynamically.
---textfile---
ownerFields_text
--------------
private void writeToApp(string readIn)
{
TextBox txtBox = new TextBox();
txtBox.Name = readIn;
txtBox.Text = "Why wont this work"; //line doesnt work ownerFields_text.Text = "hello"; //line works
}
Although looking in the properties in the debug windows for txtBox,shows property name=ownerFields_text, but its just not printing "Why wont this work". I do not want or cant cycle through controls for the right one.
Thanks.

So you create a new TextBox, give it a name and some text.
Fine.
This has nothing to do with other TextBoxes that may already exist.
It will not magically point to an existing TextBox with the selected name!
If you want to set the text of MyFirstTextBox, the one direct way to do this is
by MyFirstTextBox.Text="new text";
If you want to modify one of many existing Controls, you either need:
1. a lot of code (one piece for each Control), say a switch
2. or a Dictionary that maps names onto Controls
3. or Reflection

You are creating a new control that isn't displayed anywhere. Giving it the same name as another control doesn't automatically transform your new control into that control. They are still separate objects.

If you don't have a reference to the control, you have to. You can use the Find method to do it for you.

Hi,
I am currently developing some application which have a lot of controls on them, especially an explorer bar which when the application window appears, is actually empty and white for a few seconds and then it is populated.
I am wanting to know if it possible and how I would implement a splash screen that is shown and updates a status label on the splash form, which stays until all the controls on my mainForm have been drawn and populated.
I am programming in C# in the MS Visual Studio 2005 (Vista) environment.
Thanks, Andrew Robinson.

Hi Andrew,
a splash screen is a popular topic, I suggest you search CodeProject for
some highly rated articles about it.

In fact, NONE of the splash screen components/classes I saw for .NET were of any use to me.
And I search a lot and found a lot...

|

Really? Maybe you should write an article about the subject then...

No chance - I have no clue either; otherwise I wouldn'T have searched

I thought there was a splash screen component built in, but a splash screen is just a form. Use the Show method so that it doesn't stop the rest of your app from running.

Hi,
I am using a lot of controls on my main form, and require the splash screen to be shown until all the controls are drawn. I am using the AppLoader Quick n Dirty in C#. I have the splash working but don't know how to make it stay until the main form has completed loading and populating a control.
Any help is appreciated.
Thanks, Andrew.

Hi, maybe you should use the Activated-Event of the main form. This event occurs when the form has completed loading!

i want my code to accept only numbers as the input in this calculator code.....how can i do that
class Program
{
int operand1;
int operand2;
char oper;
int result;
public void Display()
{
Console.WriteLine("Enter the value of operand1");
if (operand1 < 48 && operand2 > 57)
{
Console.WriteLine("");
}
operand1 = Int32.Parse(Console.ReadLine());
Console.WriteLine("Enter the value for operand2");
operand2 = Int32.Parse(Console.ReadLine());
Console.WriteLine("Enter the oper");
oper = Convert.ToChar(Console.ReadLine());
}
public void Result()
{
switch (oper)
{
case '+':
result = operand1 + operand2;
break;
case '-':
result = operand1 - operand2;
break;
}
}
public void Displayresult()
{
Console.WriteLine("{0} ", result);
Console.ReadLine();
}
public static void Main()
{
Program obj = new Program();
obj.Display();
obj.Result();
obj.Displayresult();
}
}
}
thanks

Use Int.TryParse() in order to check if the string is an integer

hi ,
thanks but can you be bit more specific ie wer should i use this
thanks
C#

You should use it instead of Int.Parse() Have a look at documentatio in MSDN, it shows how to use Int.TryParse()

Hello,
I wrote the following code to get a list of available drives letters:
<br />
using System;<br />
using System.Collections.Generic;<br />
using System.Text;<br />
using System.IO;<br />
<br />
namespace drives<br />
{<br />
class Program<br />
{<br />
static void Main(string[] args)<br />
{<br />
int intFirstDrive = Convert.ToInt32('A');<br />
int intLastDrive = Convert.ToInt32('Z');<br />
List<int> intAvailableDrives = new List<int>();<br />
for (int i = intFirstDrive; i <= intLastDrive; i++)<br />
{<br />
intAvailableDrives.Add(i);<br />
}<br />
<br />
DriveInfo[] usedDrives = DriveInfo.GetDrives();<br />
int x = usedDrives.Length;<br />
<br />
foreach (DriveInfo usedDrive in usedDrives)<br />
{<br />
int intUsedDrive;<br />
string strUsedDrive;<br />
char chrUsedDrive;<br />
strUsedDrive = usedDrive.Name.Substring(0, 1);<br />
chrUsedDrive = Convert.ToChar(strUsedDrive);<br />
intUsedDrive = Convert.ToInt32(chrUsedDrive);<br />
intAvailableDrives.Remove(intUsedDrive);<br />
}<br />
<br />
List<string> strAvailableDrives = intAvailableDrives.ConvertAll<string>(delegate<br />
(int intDrive)<br />
{<br />
return Convert.ToChar(intDrive).ToString();<br />
});<br />
}<br />
}<br />
}<br />
but it seems that in windows vista DriveInfo.GetDrives() doesn't get network drives, is there something I can do about it?
