Hi!
When calling a namespace like using MyNameSpace.Members, lets say there is 50 classes in this namespace, are all 50 called? Wouldn't this cause a performance dip? I know in Java you can specify which classes you want to include.
How does one say, do I include the namespace, reference it or what?
Regards,
ma se

The classes are not called at all, they are simply included in the namespace lookup done by the compiler.

It might cause a slight dip in the compiler as it resolves the classes to the correct assembly, but it wouldn't affect the runtime.

Hi!
Is there a written rule as to when constructors with parameters are to be used? I usually do it like this?
MyClass objMyClass = new MyClass();<br />
objMyClass.Name = "MyName";<br />
objMyClass.Age = 26;
The following could also be used:
MyClass objMyClass = new MyClass("MyName", 26);
The reason why I asked because I once had a class that required about 30 values, and passing it in the constructor looked messy.
Regards,
ma se

If the value is required (so the object makes no sense without it) it should be in the constructor.
Besides this, use whatever makes the code most intuitive.
|
|
|
|
|
Generally, the object should be fully functional once it's created. For practical reasons you might have to make exceptions from the rule, though.
If possible you should still try to verify that the required values are set before they are used.

You only posted your first question 15 hours ago! Give people a chance to respond. Also, consider that it is possible that people here don't know the answer to your question.
Have you used an internet search engine to try and find an answer?

Hi,
Can i know how to pass the address of the variable in c#?
Following is the code in c which has to be converted into c#..
public int Largest(int *ptr,int Icount)
{
int largest =0;
largest = *(ptr+0);
for(int i=0; i < Icount; i++)
{
if( *(ptr+i) >= largest)
{
largest = *(ptr + i);
}
}
return largest;
}
plz let me know how to sent the reference and increament the pointer.

you can use ref key word in c# to send the reference of variable
public int Largest(ref int ptr,int Icount)
{
int largest =0;
largest = (ptr+0);
for(int i=0; i < Icount; i++)
{
if( (ptr+i) >= largest)
{
largest = (ptr + i);
}
}
return largest;
}

From within a property grid, I want to use the a CollectionEditor that is able to display a selection dialog once the "Add" button is clicked. That is, I want the user to choose collection items from a defined list and add them to the collection in CollectionEditor.
For example, in VS 2005 property grid of a windows form, if you want to add an image to a System.Windows.Forms.ImageList, the appropiate property grid displays an image chooser dialog once "add" is clicked. I want to implement something similar to this feature. Any ideas or hints? thanks.

I'v wrote an application to stream real-time video b/w two pcs (using RTP), when finished I noticed the poor performance and delay between them.
I wonder where can I get a real-time C# encoder/decoder to encode the video before sending it to other side?

Hi
Im a beginner, and need some help with my calculator. I have a textbox and it has buttons to calculate Addition, Subtraction, Multiplication, Division, and then also a Exponent button which takes the two values put in the textbox and makes the first value the Base and the 2nd the exponent.
Now must I create a Delegate? and call it eg. MathOp. and then have a seperate event for each buttonClick?
Plz Help
Thanks

I'd personally just do it in the button click handlers.

guys, i have a problem with sorting of a file line by line due to unknown character (box [] chracter - similar to this but no space between the lines)encountered. It is included on the given data from the past years.
During sorting line by line, the compiler encounters the box/unknown character, so the compiler will break the statement/line and will result for the new statemen/line. the problem here is that instead of one line, it produces another line to be sorted for the whole file and for that my system can not be accurate anymore.
example i have a file to be sort:
//To be sort:
hello world!
Love programming!
have fun-[]--and enjoy! //[]-illustrates the unknown chracter but no spaces bet. the lines
//after sorting the data will be arranged like this:
--and enjoy! //it will be broke into two lines
have fun-
hello world!
Love programming!
Help me guys.. Dont know what to do...
regards,
JayR

You should read the file byte-by-byte. This will prevent your application from getting a new line everytime it encounters one of those funny block characters.
BTW I think that character is either 0x10 or 0x13, this means your file is either using a linux type of linebreak, or is using incomplete linebreaks. You can check this by splitting the data on one of these characters.

Hi!
I developed a small C# FTP backup application (it downloads constantly from 3 FTP servers, using 3 threads). On my laptop with XP Pro it works without problems, it's running from 3 days ago. But if I try to run it on my company's server (which has Win 2003 Server) this little program crushes without any error. Simply disappears, sometimes after 15 mins, sometimes after 2 hours...
Anyone has a clue to what's happening?

Hi,
Did you use try...catch blocks in your application to handle exceptions?
If so, do they ignore any exception (This means, not displaying it in an errormesssage or logging it)?
I think your program is crashing in one of the threads and you catch the exception, but doesn't display it. I think this because your program doesn't display any errormessage (which every app should if it has an error and you don't catch it).
Regards
WM.
