Re: making auto serial number for each build of project

Yeah, I know, but the various parts of the serial may have special meaning. Since the OP didn't specify that, I thought I'd demonstrate that *anyone* can use google.

Would a unique assembly version number do the job? You can get one using:

[assembly: AssemblyVersion("1.2.*.*")]

See here for how the numbers are generated:

How to build reportviewer using existing dynamic dataset without report wizard

9-Jun-10 8:24

So lets say I have Form1

in Form1 I want to build a reportviewer1 linked to an reportex.rdlc.

I have designed the rdlc and when the code executes it creates the dataset that is returned as dsCount

DataSet dsCount = ConvertDownloadAuditToDataSet(daCountList);

I want reportviewer1 to bind this dsCount to the report.

I know how to build on creating a xsd dataset but when I have an embedded dataset Im not sure how to bind it

Hi to all,

I want to know,
How to convert => A string of "char" into Text or Bytes information coded using (ISO/IEC 8859-x) character sets according to language used for string of "char" ? Language can be any regional or international.

Thanks & Regards,

How about:
Encoding.GetEncoding("iso-8859-1").GetBytes("your-string");

Thank you very much for ur help.

I will try it.
I have to use character code tables ISO/IEC 8859-5 to ISO/IEC 8859-15 & few others (from Annex A.2 of 'Specification for Service Information (SI) in DVB systems' http://www.dvb.org/technology/standards/a038r6.tm1217r17.en300468v1.11.1.pdf[^].

Will it work with it?

Is there any way to identify character code table of a given string?

Thanks & Regards,
Aniket A. Salunkhe

Have no idea, whether it work with DVB systems and don't want to read the specification :p
No, there's no built-in mechanism to identify the encoding.
But there are some open-source encoding detectors, here are some examples:

public List<string> GetList()
        {
            List<string> list = new List<string>();
            return list;  
        }

But as per msdn we should not expose the generic list.

Hi,

1.
there is nothing that prevents you from returning a List (or any other collection) like that.
There may be "good practice" or "OO" reasons not to do so under certain circumstances, but it is perfect C#.

2.
see 1.

3.
if you look through the MSDN documentation, more particularly the properties of Dictionary<Tkey, Tvalue>, you will notice it is all there.

That seems kind of inefficient. Does that mean there are now two copies of the same data in memory? (Actually, with their crappy sample, the array at the end of the Main() method makes a 3rd copy).

No. The way I understand it the ReadOnlyThingy is just a wrapper; it holds a reference to the original collection (and that explains how it tracks the changes to the original collection, see the example), but offers fewer valid operations on that collection. So nothing gets copied.

I haven't used it ever yet, as I see not much point in making the collection read-only, while the items in the collection remain as they were, modifiable at will (except for the silly example that used strings of course).

I use them quite a lot. Many times I want a collection to be exposed but not have add and remove methods etc as I don't want the collection itself to be modified. I find it very useful!

Try using a custom iterator. Passing back a generic list is wasteful in some cases anyway.

public IEnumerable<String> GetStrings(){
     foreach(var str in stringList){
         yield return str;
     }
}

You can do it that way (and IMHO, if the compiler lets you do it, nobody else has the right to complain, coding style guidelines in force not withstanding), but to ease typing, I create a class derived from the desired collection type:

public class ListOfThings : List<Thing>{}

That way, I can pass/return a ListOfThings object instead of having to type all that crap over and over again.

public ListOfThings GetListOfThings() { get; set; }

I can also add custom methods to the class that perform Thing-specific functionality.

List<thing> - a little shorter
ListOfThings - a little eaiser to read
ThingsList - even shorter and still easier to read - WINNER!

It is code analysis that tells to return collections in stead of List. You can make use of a global suppression file in your code to get rid of it.

For dictionary, it would be suggesting a read only collection. Suppress that too if you do not want another object to be returned.

It is up to you to decide till when you are going to follow MS code analysis. I personally follow everything it tells.
