hi all,
This is what i found on the web

public static PdfFileSpecification fileEmbedded(PdfWriter writer,String filePath,String fileDisplay,
byte[] fileStore,int compressionLevel)
{
Parameters:
writer - the PdfWriter
filePath - the file path
fileDisplay - the file information that is presented to the user
fileStore - the byte array with the file. If it is not null
compressionLevel - the compression level to be used for compressing the file it takes precedence over filePath

} <---- what to type inside?

So this help to transfer the html that have been converted to pdf to store inside a file ?

does anyone know how to convert html to pdf using C#?
Cause the web i find are about java

Thank you

well, did you look into the java code. If you know C#, it should not be that hard to understand the java code.

Oh didn't you notice, analogous to square roots, they recently introduced rectangular, circular, and diamond roots to determine the size of the corresponding shapes when given the area. Luc Pattyn[^]

I have a main form, from which i recive data from an usb hid device, i work fine

In my my main form i have th code

Form.ActiveForm.Invoke(new BuzzCmdDelegate(BuzzCmd),new object[] {1,1});

I work alost, but i invoke on the main form, instead on invoke on the active form,

Both in my mainform og subform which is NOT an mdi child, i have pulic method called BuzzCmd.

How do i call BuzzCmd in the activeform from the main form?

you can use edit button on right-bottom of message Wink | ;)

if all forms have same type then you can convert to that type and call the BuzzCmd

((Form1)Form.ActiveForm).BuzzCmd();

Hmm i work sorta, but which that method i have to cast every single form i have, now i have a rather simpel proejct where i can used that method, but if i have a proejct with many forms, i have to cast all 36 forms in 5-6 diffrent events, there much be something smarter.

if all 36 forms have same method and they are differ then why dont you create a base class add that method as virtual then override. Then you can convert it to that base class and call it.

but if you want to use Invoke() then the code you using suppose to work

thomaxz.tc10-Mar-09 4:27

10-Mar-09 4:27

I don't get it, Base class? What do you mean?

Thsi i try to do is

Usb hid->MainForm (data arrived method)-> BuzzCmd (mainform)
-> BuzzCmd (frmAbout)
-> BuzzCmd (frm1)
-> BuzzCmd (frm2)
-> BuzzCmd (frm3)

depending on which one is active

Which i tried with

Form.ActiveForm.Invoke(new BuzzCmdDelegate(BuzzCmd),new object[] {1,1});

Which did'nt do as i have xped invoked on active form, but invoked on the form which the code was in.

Then you come with

((frm1)Form.ActiveForm).BuzzCmd(1,1);

I worked i then think what if i cast it to form

((Form)Form.ActiveForm).BuzzCmd(1,1);

But can't do that, because form doees not contain an medthoed BuzzCmd.

Edit:

Hmm, I try to make an form, with at virtual medthod, but wheni cast it to that, no form geet called, not the mainform, not the frmABout and not the Form1, when i try to overide i frmABout it says ther is no method to overide.

Ahh, now i get it, i make new form, which has only one method

public virtual void BuzzCmd(int handset,int button)

in my frmAbout i change to

public partial class frmAbout : Form1

rather than the standar class

public partial class frmAbout : Form

the i in frmAbout, ovveride the inheretens medthod

public override void BuzzCmd(int handset,int button)

Then i in my mainform cast to the form which onlye have the virutla method

((Form1)Form.ActiveForm).BuzzCmd(1,1);

That worked Smile | :)

Thank you.

Reversing letters in a word

thats right... Thumbs Up | :thumbsup:

OK, well I'm trying to make a program that takes a sentence as an input and reverses the letters in each word while keeping the order of the words the same i.e. "Hello World" becomes "olleH dlroW"

This is what I have come up with so far, it can post the letters of the words and keeps the words in the correct order but i can't figure out how to reverse the letters

Here is the Code:

Console.Write("> Please enter an input\n> ");
string userInput = Console.ReadLine();
string[] words = userInput.Split(' '); // creates an array of strings

foreach (string word in words) // loops through the array "words"
{
for (int i = word.Length; i >= 0; i--) // loop through word with for loop.
{
Console.WriteLine(word.Substring(0+i));
Console.ReadLine();

One last point, I'm trying to do this without using the reverse function

Thanks in advance for any assistance you all can lend me.

Use ToCharArray method an then manually create reversed word.

char[] chars = "ABCDEFG".ToCharArray();
Array.Reverse(chars);
string reversedString = new string(chars);

it will reverse whole string, but you can do with words

Adn only half a dozen lines of code:

string[] split = inputString.Split(find this out as it is easy);
for (<iteration>>)
{
   char[] chars = split[word].ToCharArray();
   Array.Reverse(chars);
   split[word] = new String(chars);
   }
String outputString = String.Join(it's amazing what 18sec of google can do);</iteration>

Should keep him stumped...

As you're trying to reverse a string, why are you splitting it up? You don't need to do that.

Yes he does, he wants to reverse only the letters in the words not the words themselves - if his example is correct..

edit: sorry about the double post, I got a strange error and the post didn't show up so I posted again..

Actually, you don't - you can do this with a regular expression and a little bit of mojo.

I can't think of any way to do it with a regex that does not split the string and does not limit the words to a constant length - so please tell me, how?

It's probably easier to just split the string though

Hi,

that is too easy an assignment. Why don't you write code to flip the characters, so
"hello world" becomes "plɹoʍ ollǝɥ"
