Hello
I am calling a piece of code in all my aspx.cs pages, which is like an error trapping class.
Can I create an actual class, and then include this class in my aspx.cs pages, so if I do have a change I can make this change in one place, in this one class instead of all my aspx.cs pages?
How would I go to call this class?
I was able to create a stand alone class but how to include in my aspx.cs pages?
Thanks!

Inheritance will solve your problem. You create a base page based on the built-in Page object:
public abstract class MyPageBase : System.Web.UI.Page {
}
Then in your codebehind files, you can inherit from the class:
public partial class DefaultPage : MyPageBase {
}

If you are really trying to implent a top-level exception handler to trap all errors,
you might like to use the Application_Error method in Global.asax. There is an whole knowledge base article about it here[^]. This has the added advantage of trapping some extra [mostly unlikely] errors.
In all other cases Matt Meyer's answer is excellent.

C# 3.5? list1.Intersect(list2)[^] (it's an extension method in System.Linq)
If not, it's trivial to produce a naive implementation which will be fine for small lists:
IList<T> Intersection<T>(ICollection<T> one, ICollection<T> two){
IList<T> r = new List<T>();
foreach(T t in one)
if(two.Contains(t)) r.Add(t);
return r;
}

You've been around long enough to know and understand the forum guidelines. DON'T REPOST. You asked this same question four hours ago in the C# forum, it has nothing to do with ASP.NET. If you didn't receive an answer, wait. Don't repost.

I think he should delete the other one, not this one, though. C# forum is the correct place for it, the other one is misplaced (and I didn't see it there since I don't read the ASP.NET forum  ).

Consider using HashSet instead.

I would be willing to be that you need to update your .net install.

I've looked all over the internet for a formula to calculate the start angle and end angle of an arc. It's very awkward since the angles go in a clockwise motion. The parameters I have are, (X1, Y1), (X2, Y2), ArcCenter, Radius. I'm pretty sure the calculation uses Atan2 as I have tried to figure it out myself.
Thanks

Start angle = atan2(y1-yc, x1-xc)
End angle = atan2(y2-yc, x2-xc)
... with (xc,yc) being the centre point.
If that isn't right, try switching the parameters or putting minus signs in. That will give you an arc but I'm not sure where it starts from.
Specifying the radius is not necessary if you specify the three points explicitly.

hello guys... I am trying to get my first crystal report printed but seems to be having a problem I am unable to trace. I added a report to my (Windows Form) project, then added the dataset to it and finally added the following code. This does not show any error but does not show data either. Here is what I tried
private void Form1_Load(object sender, EventArgs e)
{
CrystalReportViewer crv = new CrystalReportViewer();
string ConnString = "Data Source=srv032k3; Initial Catalog= MuzeDB; User ID=muze; Password=saeedasd";
string query = "SELECT * FROM students";
try
{
SqlConnection conn = new SqlConnection(ConnString);
SqlDataAdapter da = new SqlDataAdapter(query, ConnString);
DataSet ds1 = new DataSet();
da.Fill(ds1, "students");
rpt.Load("D:\\Projects\\CrystalReportsApp\\Report\\StudentsReport.rpt");
rpt.SetDataSource(ds1);
crystalReportViewer1.ReportSource = rpt;
}
catch (Exception ex)
{
MessageBox.Show("Something went wrong: " + ex.Message, "Error", MessageBoxButtons.OK, MessageBoxIcon.Warning);
}
}
|

I think your problem is here
SqlConnection conn = new SqlConnection(ConnString);
SqlDataAdapter da = new SqlDataAdapter(query, ConnString);
I think it should be
SqlConnection conn = new SqlConnection(ConnString);
conn.open;
SqlDataAdapter da = new SqlDataAdapter(query, conn);

A mistake that should not have been made. But still the problem is not resolved.

That is rather indefinite.
I am guessing that you mean that it doesn't show anything at all.
The reason I think that is that I googled for examples.
And one of the shows the use of the 'Visible' property which is a property of the parent of that class. The description of that suggests that it must be true for display to occur.

Hey everybody.
I have a very small trouble...
List view double click event is getting invoked if I am doing double click on its scroll bar.
How to avoid this...
Thanks in advance..

what are the features of row docking. is it something like data rows on top and stay on their fixed positions. If so how we can use it.
|
|
|
|
|
Is this a feature that the user has asked for? If so, why not ask them what they mean by this? It could mean 2 or 3 things, so it's best to find out out what your users think as it's them you should be satisfying.

Yes, Hanlon is right, you have to ask them "what they mean by this? It's best to find out out what your users think as it's them you should be satisfying."
In the mean time if you want to know what row docking means. I'll give you an overview about it. Row docking is accessible via Row.Dock property and we can specify multiple docked rows. If our data grid already has docked rows, the next docked row will be placed after the previously docked row and before the first non-docked row. Docked rows can also be filtered or grouped as any other data rows.
To get in depth go here about row docking
Hope it will help you.
