There are some alternate solutions here for custom modal popups, I believe, you can try searching for them.

Unable to debug these expressions

Hi,

I have following two expressions in my for loop, I don't know how to debug them.

(i = j + k) < 30;

j = (k = j) < 0 ? i : i

These expressions are used in the following for loop

for (int i = 3, j = 0, k = 1; (i = j + k) < 30; j = (k = j) < 0 ? i : i)

What is the o/p of these expressions, I haven't used these type of expressions in my coding. Can anybody please help me, any idea, or link or any example would be greatly appreciable. Please help me I am in need.

Thanks & Regards,

Where did you find that weird code for generating a Fibonacci series?
Well, that's what I found when debugging. Why is debugging complicated?

for (int i = 3, j = 0, k = 1; (i = j + k) < 30; j = (k = j) < 0 ? i : i)
{
    System.Diagnostics.Debug.WriteLine(string.Format("i={0}, j={1}, k={2}", i, j, k));
}

Stepping thru it, you'll see that the start value of i can be anything, because it will be set to j+k when the condition for the loop is checked.
And j = (k = j) < 0 ? i : i always does k=j followed by j=i, only written in a way to obfuscate things.

Extend the session timeout in the webconfig by

It does not have to be specifically 540, you can make it any length of time that you deem it to be necessary. According to documentation, it is the number of minutes until time out.

C# web form delegates

In a C# 2010 web form application, I need to make a change where some logic is hard-coded and I want to obtain the values from a sql server 2008 r2 database.
Before I make any changes, I want to make certain I understand how the existing logic work.
In a microsoft training class for C#.net, I learned about delegatesand worked on 'labs' to teach you the concepts.

When you look at the code I listed below:

LabelCustomerName.Text += transaction.CustomerName;
 LabelCustome_Status.Text += transaction.Customer_Status;

you can see the customer name and customer_status are placed into
textboxes.

I am guessing that the fields to the right of the += are delegates.
If this is true, can you tell me how to find the original location where the values are obtained from?

If these are not delegates, can you tell me and/or point me to a reference that will help me determine where the orginal values are obtained from?

Should I use system.reflections? If so, can you tell me what code to use so I would know how to use system.reflections?

In this particular case, the fields on the right are not delegates (i.e. in C terms, a function pointer).
This is an assignment operator. This does a simple concatenation on the LabelCustomerName.Text value.

You can read more about this operator here[^].

A delegate is added to an event / eventhandler combination.
For e.g. if you had used the Label's Keydown event, you could have added a delegate that allowed a certain method to execute everytime keydown fired.

E.g. LabelCustomerName.KeyDown += MyMethod(object sender, KeyEventArgs e);

There's several different ways. You can use Crystal Reports or any reporting tools out there. A google search will bring up quite a few for you.

You may want to look into Microsoft Reporting Services[^]

You can choose from one of various tools / third parties available i.e. Crystal reports, Active reports etc.

Using the ASP.NET 2.0 ReportViewer in Local Mode[^] uses the report viewer control.
