You can't write a .NET function that does the same as that PHP code, as there are no binary strings in .NET. A PHP character is an eight bit value, while a .NET character is a 16 bit unicode character.
Binary data in .NET is usually represented as a byte array:
private byte[] HexToBin(string data) {
int length = data.Length / 2;
byte[] newData = new byte[length];
for (int i = 0; i < length; i++) {
string value = data.Substring(i * 2, 2);
newData[i] = Byte.Parse(value, NumberStyles.HexNumber);
}
return newData;
}

Actually - I can:
private string HexToBin
{
string newData = "";
if (data != "")
{
for (int i = 0; i < data.Length; i += 2)
{
string hexValue = data.Substring(i, 2);
string binValue = string.Format("{0}", <code>Int32</code>.Parse(hexValue, NumberStyles.AllowHexSpecifier));
newData += binValue;
}
}
return newData;
}

That depends on what you mean by "work". They both do something, and the result is the same in both cases, but neither of them produce a result that is useful in any way.
If you have a string containing hexadecimal values, like "07FF10", that code will produce a string containing "725516". That's not a binary string as all, it's just a string containing the digits from the decimal representation of the hexadecimal values. It can't be used for anything at all, not even reproducing the hexadecimal string, as is't impossible to determine where one value ends and the next one begins.

The original question was regarding the similarity in functionality, not what the result is to be used for. So back to the original intent - does the C# version do the same thing as the PHP version?

No, they don't, as they can't. As I explained, strings doesn't work the same in .NET as in PHP, so there is no .NET equivalent of the PHP binary string.
If you want to work with binary data in .NET you use a byte array instead.
If the binary data represents encoded text, you use one of the Encoding classes to decode the data back to a string. If the binary data for example is text encoded as UTF-8, you use the Encoding.UTF8.GetString method to decode the byte array into a string.

I finally got a chance to try this at home, and here's the C# version of the PHP code posted in the original message:
private string HexToBin(string data)
{
string newData = "";
if (data != "")
{
for (int i = 0; i < data.Length; i += 2)
{
string hexValue = data.Substring(i, 2);
newData += Convert.ToChar(Byte.Parse(hexValue, NumberStyles.HexNumber));
}
}
return newData;
}

That function doesn't do the same as the PHP function.
As I already explained, you need to use an Encoding class do decode the data if you want the result as a string. Now you are just taking the data and using it as unicode character codes. That only works for the characters that happen to have the same character code in unicode as they have in the encoding that was used to create the data.

Hi,
I have problem in Fileupload, it will postback. Is there a way to prevent from posting back?
Thank you

No. The file data is sent in the request to the server. No postback, no upload.

How can we control the process to execute it just only once?
Because, I have one button wherein the process will upload the excel file and at the same time will add the number of quantities into the database.
If this will be the case how can I control the process, because it will affect also on the adding of quantities, it will result to times 2 which is not correct.

One thing you can do is, on your postback, once your code has processed the postback, in your prerender, redirect to the same URL, and put something on the query string to make the page reload it's data. This way, a refresh will not perform the postback again.

YES!
It is working fine now. I just transfered my source code into the prerender then the result perfect, exactly as what I need.

Are you new to web development?
If so, I'd suggest buying (or finding a friend that has -- i cannot suggest pirating in good conscience, but it's there) a good book on it.
Specifically, Beginning ASP.NET 2005 in C#. (or VB.NET if you prefer) Published by Apress. Between $30-40US.
http://www.amazon.com/Beginning-ASP-NET-2-0-2005-Professional/dp/1590595726/ref=sr_1_4/105-1894697-3759602?ie=UTF8&s=books&qid=1190778126&sr=8-4
In fact, I still have my series of Apress books I keep for references. They come in handy.

Hi everyone!
I have a html page with an IFrame; and the following code:
var doc = document.getElementById("iframe_id").contentDocument;
doc.body.innerHTML = htmlCode;
This code is run in body's onload handler. 'htmlCode' contains some (very simple) html (it is a string, of course).
I was able to test this code only in Safari 1.3 (Mac), and it didn't work 
BUT: I need to test it in a Safari 2.0.4. Unfortunatelly, I don't have access to it. Anyone (with Mac) can tell me if it will work?
And why the above code didn't work with Safari 1.3? Is it possible to fix it?
Thank you very much in advance!
P.S. I understand it is a MS-centric forum, but... I do hope.

You might have better luck with writing the entire page into the iframe. Example:
var doc = document.getElementById("iframe_id").contentDocument;
doc.open();
doc.write('<html><head><title></title></head><body>'+htmlCode+'</body></html>');
doc.close();

Ok, this variant does work But what to do with the original code? Does it work in the Safari 2?...
Thanks anyway.

That code does work on Safari for Windows, although it's a little bit different in size and exact location.
