my code are
SqlConnection cn=new SqlConnection(ConfigurationSettings.AppSettings["con"]);
SqlDataAdapter ad=new SqlDataAdapter("select * from printfees ",cn);
fees dt=new fees();
//fees is the name of typed dataset
ad.Fill(dt);
CrystalReport2 crv1=new CrystalReport2();
crv1.SetDataSource(dt);
crv1.RecordSelectionFormula="{printfees.registrationnumber}= '"+txtregistration.Text+"' ";//and {printfees.feesofmonth}='"+txtmonth.Text+"' and {printfees.session}='"+txtsession.Text+"' ";
CrystalReportViewer1.ReportSource = crv1;

Still not quite understanding what is your problem.
By the way, it is better to filter data that only you need first in your SQL, rather than pull ALL data into a dataset then pass ALL the data to Crystal Report to let Crystal Report filter the data.

You can't. Wordpad is just a simple throwaway app that reads most of a Word doc. Word is an application that has full suppor for external control.
As someone else said, ask your question once, not three times.

Learn English a bit better. Your past two posts are poorly constructed and make no sense. You cannot use MS Word inside of your C# app (embedded in it if that is what you are trying to do). You can, however, use Microsoft Interop classes to bridge with Word.

how i can take an array with it's value from form to another
and i need to use this array after closing the form.

Do you mean that u have a form with few TextBoxes and you want to save values in these TextBoxes in an array?
Try this then:
string[] arr = new string[numberOfTextBoxes];
arr[0] = textBox1.Text;
arr[1] = textBox2.Text;
or, if you load TextBoxes dynamically:
List%lt;string> lst = new List<string>();
foreach(Control c in this.Controls)
{
if (c is TextBox)
lst.Add(c.Text);
}
string[] arr = lst.ToArray();

Thanks in advance

An example:
you declare an array in form1
Public Static String[] arr = new String[100];
And in form2 you can do form1.arr[1] = "";
See that an array uses a fixed size, if not desired, you'd might checking out ArrayList.

Close 
1) It should not be static if it is related to the instance of the form (which it is given the example).
2) It should not be public as it is a field. Make a property instead.
3) ArrayList was something we used back in the old days, now we use ObservableCollection<t> or at least List<t>.

hehe
1) Yes correct, but if it is an object that is between those forms only it isn't so bad if it is static (shared in vb.net) you just need to keep your head with in updating the object
2) yes, totally true, better is to make it a property, maybe I gave to much a quick and dirty solution 
3) I didn't know the ObservableCollection and I looked it up and it is for .NET 3.0 only. I am using ArrayList a lot and it is working great for me But maybe List is better because you have the sort things etc...
Thanks for the added value, I can learn from it

1) A lot of beginner in OO have problem with the difference between a class and an object. Hence it is a problem "mudding" the concept by using statics.
3) The main reason to use List<t> is not that it has sort etc (ArrayList has that as well). The reason is that it is strongly typed. Besides making the code a LOT easier to write (and read) it does offer some performance benefit on value type collections as well. It's not just the ArrayList that has been replaced - you have Dictionary<keytype, valuetype=""> instead of Hashtable etc.
The System.Collection.Generic still have on main problem: They do not raise events when changed... which pretty much means they are useless in a lot (if not most) cases, as you can't build a prober UI on them.

hi guyz!!
I have a problem with datepicker, i want to know if the dropdown is currently open or not.. i need that in my condition, i really need your help, tnx in advance.
|

|

I'm going to assume you actually mean the DateTimePicker[^] control. In order to do this, you will need to handle the DropDown[^] event, which occurs when the calendar dropdown is shown, and the CloseUp[^] event, which occurs when the calendar dropdown is dismissed.
