When I am using a varible inside a method (let's say 25 lines of code)
Should I create an int variable or Int32? What the heck is the difference?
I didn't get any requirements for the signature
|
|

There is no difference. int is a C# keyword that's simply an alias for System.Int32.

Oh, that clears it up then. I suppose string and String are the same as well?

The Framework classes have names starting with an uppercase letter,
such as System.String
C# has type specifying keywords in lowercase, each of them corresponds
to one of the System.Xxxx types. Yes string corresponds to System.String

this weeks tips:
- make Visual display line numbers: Tools/Options/TextEditor/...
- show exceptions with ToString() to see all information
- before you ask a question here, search CodeProject, then Google

Here's a hint: if you're in Visual Studio, hover your mouse over string, or double, or int, and it should pop-up a little info showing the aliased type.

Not quite. Please read the documentation on this more carefully. I believe int in a 32-bit system is 32 bits as suggested, but in a 64 bit system, int becomes 64 bits.
As a result of that information, when it is known that 32 bits will suffice, please be sure to use Int32. Otherwise, when your program is run on a 64 bit system you could have unexpected results.

That is completely false, don't listen to him. Jeez, the misinformation is astounding.
In .NET, a C# int just aliases System.Int32, which is 32 bits no matter what operating system you're on, including 64-bit OSes.

oh.. Thanks... Judah. it's the best if it's like that.. We, .NET dev, won't need to care about what OS the users are running.. good.

That's completely false. In .NET a C# int simply aliases System.Int32, which is *always* 32 bits, regardless of whether you're running on a 64-bit OS.
Now, in native C++, int may be different widths on different operating systems. But if you're coding in .NET, an Int32 is always 32 bits.

I need proof (besides the MSDN documentation) that int is always 32 bits. Will MS change their minds about the size of int in the future? Who can tell. For those reasons it is always best to ensure that you know the size of the variables that are in use.

i want to create accont book using c#

Well, I guess you should give it a go and let us know how it goes. No one here is going to write it for you. Once you start writing the code, if you run into specific problems you would like some help with, let us know and we will try to help you with your specific problem. If you are looking for something that is already written then seach the codeproject site or google.

start from looking at some sample account books....
and make a work breakdown structure of your activities
and then start writing code for your each activity
and if u face any problem then write about it

Hi, I'm writing a Media Player App in C# and would like to know how can I implement an equaliser (bass, treble, etc) in it. Can it be done using DirectShow.NET. I've read that DirectSound provides me with an option. But I'm not too sure. I would prefer a C# soultion.
Thanks...

I' going to update database by using datagrid which is connected to data base by it's datasource.
I want to change data in datagrid and then save it in my data source(e.g. dataset) then update my database with this changed data (e.g. using update command of my adapter).
I want to do these things in my winApplication!
I don't know if datagrid has any event to do these things or not?
If not what should I do?
Thanks.

Hello...
I'm new to C# and i want to train my skills with programming an Application
that looks at 3 progressbars and make the values of them "even", like
if pbar1's value is 34, it becomes 30, but if it is 36, it becomes 40.
I use it to test the Fuzzy logic dot net =x
Now this is the code i need help with:
<br />
<br />
<br />
private void button2_Click(object sender, EventArgs e)<br />
{<br />
if (chkbx1.Checked)<br />
{<br />
vbar1.Value = Random;<br />
}<br />
}<br />
<br />
<br />
"button2" is my Object for generating random Numbers for those pbars with checked checkboxes...
Now how to get that random Value from 6 to 86? please help =(
|
|
|
|
|
Use the System.Random class...
Paul
|
|
|
|
|
System.Random is the same as Random D:
someone please explain me =(
|
|
|
|
|
Call the overload of System.Random.Next that accepts 2 arguments. The first is your min value, the second is your max value.
This is all explained in the documentation...
Paul
|
|
|
|
|
just create a new instance of Random class like
Random rnd=new Random();
use the next method for generating random number
int randomNumber=rnd.Next(6,86);
good luck
|
|
|
|
|
omg there is no next method...
Maybe i forgot a using directive?
there are only 2 methods on Random... it's
Equals
and
ReferenceEquals
