Re: NmericUpDown - set the Value outside the range. HELP!!!

8-Jun-07 6:42

It is not my idea Smile | :)

But I was asked to do it.

Maybe there is the way to cancel the check of the bounds performed by the control, somehow ?

Nope. There's no way to get the value outside the bounds, unless you increase. the Max bound.

You'd have to create your own version of the control to get any additional functionality.

So, say you ARE successful at getting the value outside the bounds. Why 30? What is supposed to happen when the user types a value into the text box? What if he/she clicks on the Up and Down buttons? If the value supposed to shoot down into the valid range?

If you need some kind of flag denoted by the value 30, why not just replace that with a checkbox? If the box is checked, the numeric control gets disabled and a flag is set. If not, the numeric is re-enabled and the flag is reset.

I know, I know Smile | :)

All these thought were the first things that came to my mind when I've got this assignment, but for some reason they whant it to be done this way. Eventually, offcourse, we will do it as you are saying, but first I have to proove that it is not possible to impliment it the way they want Smile | :)

So, any ideas on the stated problem?

Maybe I can unsubscribe from the eventhandler that checkes this Value? Is it possible? Just I do not know which event is handling this, but I have a feeling that I know the function, which handles this. Any ideas?

Re: NmericUpDown - set the Value outside the range. HELP!!!

8-Jun-07 6:54

You never subscribed to one in the first place, so no, you can't unsubscribe from it. Also, this isn't done by an event handler. The check is done inside the Value, Minimum, and Maximum properties. No events are fired to trigger this check.

Are you sure? If it is so, than there is really no way around it. Good ! Smile | :)

How do you know that? I could not find such a precise description anywhere.

Go get Lutz Roeder's .NET Reflector and look at the code in the NumericUpDown class yourself!

You can inherit this class to realize this feature for derived class.

I also need the Min and Max to be set, so the user knows the bounds.

String to Byte Array Conversion

I want to convert a string to byte array as follows

<br />
byte[] b = Convert.FromBase64String(s);

it is giving the following error:

Invalid length for a Base-64 char array.

can any one give me a suggestion to solve this.

Best Regards,

I guess you could use the Encoding class (System.Text).

Encoding encoding = Encoding.UTF8;
byte[] b = encoding.GetBytes(s);

But you have to use the right encoding.

Hope this helps.

Re: String to Byte Array Conversion Thank you

For Conversion of String to Byte Array go like this,

public static byte[] StrToByteArray(string str)
{
System.Text.ASCIIEncoding encoding=new System.Text.ASCIIEncoding();
return encoding.GetBytes(str);
}

Don't go with Base 64 because it is of invalid length.

Because of an unhandled exception occurred during the execution of the
current web request. Please review the stack trace for more information about
the error and where it originated in the code.

do a string.Split and pass that Ctrl char (the square i see) ~~and~~ as the delimiter.

xacc.ide-0.2.0.57 - now with C# 2.0 parser and seamless VS2005 solution support!

Manas Bhardwaj8-Jun-07 1:32

Here you go :

String fixString = "Whateever";<br />
string[] fixArray = fixString.Split(Convert.ToChar(1)); <br />
//I used 1 because FIX message uses this as delimiter...<br />
HashTable fixTable = new HashTable();<br />
string[] fieldArray = null;<br />
for (int fieldCount = 1; fieldCount < message.Length; fieldCount++)<br />
{<br />
fieldArray = fixArray[fieldCount].Split('=');<br />
fixTable.Add(fieldArray[0].ToString(), fieldArray[1].ToString()); <br />
}

Hope this helps.
by the way, I too used all this in my early carrier. Wink | ;)

if i am able to do it like this
100=ARCA10=169|0|
using substring
now i have to get value of first tag
eg
100=
Result should be "ARCA"
i want it in seperate string

string[] fixArray = fixString.Split(Convert.ToChar(1)); <br />
//I used 1 because FIX message uses this as delimiter...<br />
HashTable fixTable = new HashTable();<br />

{<br />
fieldArray = fixArray[fieldCount].Split('=');<br />
fixTable.Add(fieldArray[0].ToString(), fieldArray[1].ToString()); <br />
}<br />
string firstTagString = fixTable["100"].ToString()

This will give you string which is there in tag 100, no matter at what position it is at.
I am telling you this because FIX is a tag based protocol and not a position based. The position may vary from message to message.
It is a more generalized solution for your scenario.
Success

Ankit Aneja8-Jun-07 2:18

you do message.Length

you mean fixString.Length here
Am i right
even than its crashing for my message

My Mistake OMG | :OMG:

It should be fixArray
Here's your code

String fixString = "Whateever";<br />
string[] fixArray = fixString.Split(Convert.ToChar(1)); <br />
//I used 1 because FIX message uses this as delimiter...<br />
HashTable fixTable = new HashTable();<br />
string[] fieldArray = null;<br />
for (int fieldCount = 1; fieldCount < fixArray.Length; fieldCount++)<br />
{<br />
fieldArray = fixArray[fieldCount].Split('=');<br />
fixTable.Add(fieldArray[0].ToString(), fieldArray[1].ToString()); <br />
}<br />
string firstTagString = fixTable["100"].ToString()

Ankit Aneja8-Jun-07 2:33

8-Jun-07 2:33

its still giving index was outside the bounds of array
