Hi,
I have the following code :

SqlConnection cn =new SqlConnection(@"Data Source=ES-SYS-692\SQL2008;Integrated Security=SSPI;Database=mydb");
cn.Open();
DataSet ds=new DataSet();

SqlDataAdapter da=new SqlDataAdapter("select empno,ename,job from emp where sal>1250",cn);
da.Fill(ds,"empds");

ReportDataSource RDS=new ReportDataSource("empds",ds.Tables[0]);

ReportViewer RV = new ReportViewer();
RV.Visible = true;

RV.ProcessingMode=ProcessingMode.Local;
LocalReport lc=RV.LocalReport;
lc.DataSources.Add(RDS);

RV.LocalReport.Refresh();

This Code in a button click,when i click on the button..i ended up with nothing..unable to get the report(generate teh report).What has to be added to this code?

In the foreach loop when i use the File class which is static ,it is throwing an error.Can't we use the static type in the foreach loop?

Hi,

one more question i have is ,what's the difference between user control and Custom control.is there any difference?

M.CHAITHANYA 19-May-11 9:32am View

hi,
What exactly is creating an instance here.As the Form already exists,there is no need to create an instance right?

Hi,
-Will GetType method of assembly searches for the object provided by us?if so,will it implicitly casts to object type first and starts checking.?
-"CreateInstance"-the name some sounds like it is going to create another instance ,will thsi happen really.what exactly this method do?

Please comment on this.

M.CHAITHANYA 18-May-11 7:57am View

Hi,

Hi wayne,

It's working fine now.But i dont understand why we need to explicitly add reference.using should work right?

Hi Richard,
As stated above in he API definition ,an API is Colletion of interface methods.Here do you mean API is collection on unimplemented methods of Interfaces ,which should be implemented by the API user.is this correct ?

persisted is storing object for a long period (may be for life time).i have an eg:

namespace System
{
// Summary:
// Represents the method that will handle an event that has no event data.
//
// Parameters:
// sender:
// The source of the event.
//
// e:
// An System.EventArgs that contains no event data.
[Serializable]
[ComVisible(true)]
public delegate void EventHandler(object sender, EventArgs e);
}

here Delegate "Eventhandler" is prefixed with attribute [serializable],can you please take this example and expalin me what actually happens behind the scenes

Hi,
Happened to read the link provided by you,But i couldn't get one thing:why an object should be persisted ,when and where we use this persisted object.

Hi Abhinav,

I agree with you that the order is done in order first,second...But my concern here is suppose if we pass @sortorder as 'asc'..what will be the value of 2nd case ,I mean

"order by ename asc,?"----here what replaces question mark

Hi Olivier,

HI ,
I am sorry..you didnt get my question i guess,my question is what actually happens internally
when you make a method virtual..how does the complier treat it?

M.CHAITHANYA 22-Apr-11 5:59am View

Hi Olivier,

What actually is making Virtual?

Hi Manfred,

Who does this ?like is there any program that monitors the code and give suggestions.?

M.CHAITHANYA 15-Apr-11 2:54am View

HI,

To use the field a,i created object.

M.CHAITHANYA 15-Apr-11 2:36am View

Hi Ankit,

If it is not the intialization,with the second case block of code i am able to prit the value of a.How is this possible?

Regards

M.CHAITHANYA 15-Apr-11 2:14am View

Hi ,

I am sorry ,i missed ,But even though if i add ";",Complier is raising error:"a is used like a type".

M.CHAITHANYA 15-Apr-11 1:44am View

Hi,

where i am missing a ,in the first case i declared an integer a assigned a value to it in the next line,But in the 2nd case ,a value is intialized to a value while declaring itself..where am i missig a?

M.CHAITHANYA 15-Apr-11 0:33am View

Hi SAKryukov,

If it's elements are allocated on the stack ,why it is called reference type(as per your statement above).

Hi walterhevedeich,
I agree with your words..But if we conider the case below:
String s1;
s1="A";
string s2;
s2="B";
s1=s2
Now,is it like s1 has two references one pointig to A and one pointing to B in heap or will it point to only B?what way it is done?

M.CHAITHANYA 14-Apr-11 0:51am View

Hi Walterhevedeich,

If it so..what is the need of creating a new memory where the new value resides ,Instead the old memory can be used by replacing the old string with the new string right?

RegardsChaithanya

M.CHAITHANYA 14-Apr-11 0:19am View

Hi walerhevedeich,

The statement(taken from the link provided by you) :"the code s = s.Replace ("foo", "bar"); doesn't change the contents of the string that s originally referred to - it just sets the value of s to a new string, which is a copy of the old string but with "foo" replaced by "bar". " ,Does it mean s is pointed to new strin g values which is stored in the heap.If it is so what happens to the old value,will the old pointer will be wiped .

Hi,
Class a
{
int[] a;
}

Here array is an reference type.Do you mean(according to the statement :["A field of reference type always goes to stack."]) a has place in the stack in the above example.

Hi,
IS D an object or variable?
regards
Chaithanya

M.CHAITHANYA 13-Apr-11 10:52am View

Hi ,
Now,,Consider D has some reference ..Will it(variable D) be stored in the stack or heap?
