Hello,
I'm trying to to the following thing:
<br />
<br />
public abstract class ITest<br />
{<br />
public abstract ITest(string val);
}<br />
<br />
<br />
public class Test : ITest<br />
{<br />
public Test(string val)
{
}<br />
}<br />
<br />
Is there any possibility for defining abstract constructors ? Interfaces can't define constructors. It's not important because I realized that it is not necessary, but nevertheless it's an interesting question.
thanks,
Florian

Abstract classes can't be initialized, and constructors can't be virtual => no need for constructors.
Abstract is a class-keyword...

You have an abstract CLASS called ITest, this is confusing. The convention is that interface names start with I[interface name], not class names.
If you do need to do some common work at construction time in the abstract class then use
protected ITest(string val)
{
}

Yes, see above.

Hi Colin,
thanks for your answer. By the way: do you have a certain style for naming abstract classes (probably ATest, I guess ). I didn't changed the name because I'm used to C++ were abstract classes and interfaces are handled the same way (I do C# programming for basically 5 months now) ... so this difference in naming makes only really sense (for me), if the abstract class implements things, so it's not completely abstract anymore... but ok, C# has the interface type/definition, then it makes probably more sense.
Bye,
Florian

No, there is very little hungarian notation used in .NET. It is generally frowned upon. I for interface is one of the very few examples.

Hi All,
I am generating a set of datasets from few DataAdapters, and those generated datasets are referred in another project space as referenced dataset.
When i say
DataAdapter.Fill(datasetX, "tbl");
it does the task for me. The Memory size of the Exe in the runtime grows from 10mb to 20mb,but once i close the form the size never comes down. Even if i say
<br />
datasetX.Dispose();<br />
System.GC.Collect();<br />
And i was thinking of using 20 to 30 such datasets but will it not increase the size of my application ?
How can I bring down the runtime memory consumption ?
How can I Dispose the Dataset ?
Please help with this.
Thanks in advance

Are you disposing the connection object and DataAdapter object as well?
What happens when you open and dispose a bunch of datasets, does the memory size of the exe keep going up? System.GC.Collect(); is probably unnecessary.

No i am not disposing them , as they are dragged on to a component. and from that Adapter ->Right Click ->Generate Dataset.then i refer that dataset from my UI project.

No the size of the Exe remains the same.

Hi ,
anyone please help me how to make multiple scenorio in case. i tried with , operator but it gives error.
example,
switch(a)
{
case q,y:
...
}
|
|
|
|
|
try
switch(a)
{
case q:
case y:
{
ur calculations......(it should work for both case q and case y)
}
break;
...
}

You don't need the additional body! {} wastes some time and is often unnecessary. (I bet it pushes and pops the stack)
switch(a){
case q:
case y:
...
break;
}

Hello all,
How to get the size of reference type stucture,
ref Innerstruct
{
unsigned int j;
bool bl;
};
ref stuct sample
{
int i;
Byte b;
Innerstruct st;
};
sample s=gcnew sample;
int length=sizeof(s);
this returns 4, i thing it is the size of pointer. how to get the orginal size of structure and its members.
I posted it in C++, but didn't get reply if you know plz help

What makes you think that posting in the wrong forum will help?
With this being said, have you tried Marshal.SizeOf() ?

Hi all,
I'd like to get a book on C# and .NET which will act as a reference book and also be a gentle introduction for a C++ programmer - any suggestions?
TIA,
Steve.

C# Cookbook would be a good book to look at, you wont have any problem with syntax and OOAD, so no point in getting a book that steps you through that (since you are a C++ programmer). The C# cookbook will get you into the .Net framework and show you how to apply it correctly for a number of realworld/complicated problems from simple server side console application to remoting, threads and webservices.

hi all,
in my application when i double click a list view it opens a new form... if i double click it again it again opens a new form again .... is thr any method to find out how many forms are opened already before opening a new dialog...
thanks a million in advance.....
|
|
|
|
|
If you open a new form, you must put it in a collection.
Then you can read the "Count" from collection to know
how many forms are opened.
|
|
|
|
|
can you plz explain it more.... plzzzz
little e.g will be more helpful....
thanks a lot in advance.....
|
|
|
|
|
For example :
Just create an ArrayList.
ArrayList a = new ArrayList();
If you create a new form, for example:
Form form = new Form();
a.Add(form);
form.Show();
If you want to know the amount, then
get the a.Count
