I am doing a project which is about
Generation of html to pdf (Encryption of MULTIPLE MARKED text included, PDF document must be at least 10 pages and encryption is to be done on each page)
I am using example: ID = 1 to encrypt the text
Can anyone help me as i do not understand how to use Itext for my project.
======================================================================================================
Is like the words that are encrypted in the HTML are being hidden.
After that, i need to generate it into a pdf.
example: This is an anple
After i encrypted "This is"
In the html file <encrypted ID = 1> This is </encrypted>
After it had been generate into pdf, it will show:
<<encrypted>> an apple
This can be done into multiple encryption (more than 1 page)
So how can i do this using Itext?
Itext: iText is a library that allows you to generate PDF files on the fly.
But how do i use it?
======================================================================================================
Thank you

What is itext ? If your html is encrypted, how can you expect to make it into a PDF ? Why MUST the PDF be 10 pages ?

Hi,
I have a dataset that contains information froma database. The database has 3 columns named GlobalId, LocalId and Name. Basically the GlobalId is Autoincrimented and the LocalId is not. When I create an entry I want to check if there's a LocalId, if not then add a LocalId, if there is a LocalId then select the last one and incriment that number by 1.
My code looks like this at the moment:
private void GenerateEmployeeID()
{
int employeeID = 0;
DataTable dt = dsWBGTS.Tables["Person"];
if (dt.Rows[0][1].ToString() == "")
{
employeeID++;
lblLocalIdResult.Text = employeeID.ToString();
}
}
How can I retrieve the last number in the LocalId column and incriment that number by one?
Thank you!!

Well, for the local id to have meaning, it should always exist in the DB, shouldn't it ?

And that is why I am having this issue, because the method I am implimenting in my application should get the last LocalId entry from the dataset and incriment it by 1. The Dataset contains the latest information from the DB so obviously the LocalId will be relevant to the DB.

If your application has only one user, ever, then there's no issue with data traffic. So, ask the database. If your app has more than one user, then this approach is a disaster, so you need to ask the database to assign a number, and create the record, so the number doesn't get used twice.

you could do 'select' to get your last entry or have somewhere in your database where you keep localID value

The new id is probably an identity field in your data set. The best way to get the correct id value will be to commit the updates to the database, otherwise you will have concurrency issues.
If you really want to get the last id value from the DataTable look into the Select method.

first of all u get max of localid and then increament 1

Sit back and think as to what you want to do.

what do you think 'Add' takes as parameter? It got to be an Image Object. Don't you think?
Now look at your

ListView is just a collection of, well, items. You got your selected index, kewl, now go get your Item. What kind of object is your item? Is it am image? if not not what do you need to do to convert it to Image? Now take that Image object and give it Add().
I'm not working on windows forms, but it does not take much to figure it out. What I said may not be entirely correct, but should give you general idea.

Buy a book on C#, read it, and start with the basics. Abandon what you're doing now, you obviously don't know enough to do it well. I assume you're not being paid for it ?

You may want to go back and read what Christian wrote.
There is nothing wrong with been new and wanting to learn. But the way to learn is first to read and understand the basics.

Either you're biting off more than you can chew, or you're trying to do paid work before you know your basics. Either way, stop it.
