Hi, I Would to convert decimal to hex.
If I write
string hexValue = decValue.ToString("X");

in C++.net it's the same??
I think it's so.

Thank you.
Sara

Yes, I think so too.
If it doesn't work, try the following:

<i>string hexValue = decValue.ToString(S"X");</i>

Hi,
You can also try Convert.ToString(value,base) method.
Best Regards

It is ok but some problem is occure anyway once try it

C#
-----
String hexNumber = "000001ae";
int i = Int32.Parse(hexNumber, NumberStyles.HexNumber);
MessageBox.Show(i.ToString());

NOTE : Don't forget to include
using System.Globalization;

can u please tell me the answer, when the above code is executed

pliz provide me a java source code to convert a decimal to hex and vice versa

hi all,
i need code in C++ Language to convert from hexadecimal to decimal
please help
thanks

bayan,
In C++, use stringstream:

#include <string>
#include <sstream>
#include <iostream>

using namespace std;

string dec2hex (int num)
{
string str;
ostringstream o;
o << hex << num;
str = o.str();
return str;
}

int hex2dec (string str)
{
int num;
istringstream i(str);
i >> hex >> num;
return num;
}

int main()
{
string str = dec2hex(127);
cout << \"str is \" << str << endl;
int num = hex2dec(\"7f\");
cout << \"num is \" << num << endl;
return 0;
}

Trying that again:
#include &lt;string&gt;
#include &lt;sstream&gt;
#include &lt;iostream&gt;

using namespace std;

string dec2hex (int num)
{
string str;
ostringstream o;
o << hex << num;
str = o.str();
return str;
}

int hex2dec (string str)
{
int num;
istringstream i(str);
i >> hex >> num;
return num;
}

int main()
{
string str = dec2hex(127);
cout << \"str is \" << str << endl;
int num = hex2dec(\"7f\");
cout << \"num is \" << num << endl;
return 0;
}

bueno estoy empesando en c# y megustaria que me ayudes con este codigo pero en windos from

I got error for the above c program in windows::

Please reply to this as early as possible.

Hi i need to cnvert the following C# code inyo java. Please help me.

protected iTextSharp.text.Color getColor(string txt)
{
if (txt == null || txt == "") return Color.WHITE;
if (txt.StartsWith("#"))
{
txt = txt.Substring(1);
int res;
res = Int32.Parse(txt, System.Globalization.NumberStyles.HexNumber);
{
return new iTextSharp.text.Color( System.Drawing.Color.FromArgb(res));
}
}
else
{
return new iTextSharp.text.Color(System.Drawing.Color.FromName(txt));
}

return Color.WHITE;
}

guys from the above code for conversion with decimal to hexadecimal there is something missing.And I am not getting it.Please help.

Old thread, but meh.

[code]

static string chex(byte e) // Convert a byte to a string representing that byte in hexadecimal
{
string r = "";
string chars = "0123456789ABCDEF";
r = chars[e >> 4];
return r = chars[e

Huh, some text got cut off... here is the code

static string chex(byte e) // Convert a byte to a string representing that byte in hexadecimal
{
string r = "";
string chars = "0123456789ABCDEF";
r = chars[e >> 4];
return r = chars[e

This is not c#, but this is live :)
When I need to convert some value right away, I use this <a href="http://www.stringfunction.com/hex-decimal.html">hex to decimal converter</a>
Pretty cool!

I am surffing for a while in internet to solve decimal conversion problem finally i found a website which is very effective
to solve decimal to fraction conversion problem.. i am sharing you guys my discovery here is a URL of the website http://www.decimaltofraction.com

Helloo

test

i noticed a simple problem when converting. sometimes it will only give you one char.

here is a fix:

public string RGBtoHEX (byte r, byte g, byte b)
{
string hr = r.ToString("X");
string hg = g.ToString("X");
string hb = b.ToString("X");
hr = (hr.Length == 1) ? "0" hr : hr;
hg = (hg.Length == 1) ? "0" hg : hg;
hb = (hb.Length == 1) ? "0" hb : hb;
return "#" hr hg hb;
}

Console.WriteLine(RGBtoHEX(254,67,11));

it messed up my code.
when you see this: PP
add a (plus sign)

public string RGBtoHEX (byte r, byte g, byte b)
{
string hr = r.ToString("X");
string hg = g.ToString("X");
string hb = b.ToString("X");
hr = (hr.Length == 1) ? "0" PP hr : hr;
hg = (hg.Length == 1) ? "0" PP hg : hg;
hb = (hb.Length == 1) ? "0" PP hb : hb;
return "#" PP hr PP hg PP hb;
}

Console.WriteLine(RGBtoHEX(254,67,11));

Hello, C# code here.

"decimal" to hex (using bytes):
[code]
string bhex(byte x)
{
string hex = "0123456789ABCDEF";
return hex[x>>4] "" hex[x

Hello, C# code here. WTF my last post had stuff cut out. Try again..

"decimal" to hex (using bytes):

string bhex(byte x)
{
string hex = "0123456789ABCDEF";
return hex[x>>4] "" hex[x

thanks

fuck yo

input: unsigned byte cInput
byte cTemp = cInput;
cTemp >>= 4;
string sOrgOut = "0123456789ABCDEF"[cTemp];
cInput

Hmm.. email for reply

Tried again months later. Still nothing.

This forum is a bit... shit. Bugs are supposed to be fixed, not kept.

People deserve very good life time and loans or just student loan would make it better. Just because freedom relies on money state.

Write a DEC-HEX-OCTAL dump program, where you read an integer value
from keyboard, and display the value as a hexadecimal number (base 16) and
as a octal number (base 8) in the main routine.
Use the following function prototypes to access converted numbers:
void dec2hex(int

When you're in the corner and have got no money to get out from that point, you will require to take the loan. Just because it will help you for sure. I take student loan every year and feel myself fine just because of this.
