writer.Flush();

one remark: you oinly need to flush when you don't close right away; here you want to close, so don't flush, there is no need to. However, you should close nested things in reverse order: since you opened ns and then writer, you should close writer, then ns. That way, no flush is required.

threshold filter problem

Hello, i have a problem regarding threshold filter. The code as below:

<br />
        private void button3_Click(object sender, EventArgs e)<br />
        {<br />
            //Bitmap threImage = new Bitmap(pictureBox2.Image);<br />
           <br />
<br />
            // create filter<br />
            Threshold filter = new Threshold(100);<br />
            // apply the filter<br />
            filter.ApplyInPlace(threImage);<br />
            pictureBox3.Image = threImage;<br />
        <br />
        }

However i have this error " Source pixel format is not supported by the filter. " when the button is being invoked.

anyone know whats the problem?

must the image i apply the filter to be a greyscaled one?

Presumably you are using the AForge Threshold class[^] - it's the only one I could find on the internet that has identical code to your sample - which doe indeed state it should be a greyscale bitmap. Which makes some sense.
It might bne easier if you point your questions at the folks who wrote the code? They are more likely to know the answers to questions on their own package that a general site like this...

BTW: In future, if you are using a package, name it. It makes life easier for us all.

Ah the classic compile error problem. Try one of the following...

IMPORT EXCEL FROM SQL;
EXPORT EXCEL TO SQL;

XML Serialization

NarVish14-Nov-10 21:18

Hi,
I've class, Node, with the following properties and these are the attributes of XML element.

XmlAttribute("id")]
public string Id
{
   get { return m_id; }
   set { m_id = value; }
} 
[XmlAttribute("char")]
public string Char
{
   get { return m_ch; }
   set { m_ch = value; }
}

When this is serialized, it created the xml elements as below

 <Node char="_" id="S_SEPARATOR">
<Node char="" id="S_BLANK">

The requirement is, if id is "S_BLANK", it shouldn't show "char" attribute, as below.

<Node char="_" id="S_SEPARATOR">
<Node id="S_BLANK">

Please guide me to get this output. Thanks in advance.

Hi,

you can use the ShouldSerialize* pattern
where * is the property name that's supposed to be serialized

public bool ShouldSerializeChar() { 
        return !"S_BLANK".Equals(id); 
}

Cheers

Manfred

Thanks for your reply. Where should I call ShouldSerializeChar()?

Manfred Rudolf Bihy14-Nov-10 22:14

14-Nov-10 22:14

This function is not meant to be called by you.
It's called by the XML serializer. If the serializer
sees a property with say an XMLAttribute it knows
it should serialize it. Then it checks if there is
a method bool ShouldSerialize(Property name here).
If it finds such a method the serializer calls it
and uses the return value to determine wether it
will really serialize this attribute or not.

Best Regards,

Manfred

Don't post the same question in multiple places - all you will do is duplicate effort and annoy people.

Ooh goody. You want us to tell you how to avoid a site's CAPTCHA so that you can bombard it with crap. You aren't going to get help from anybody here with an ounce of ethics in them.
