Hi I am designing an XSD schema in which there is a field called SSN. This field has some restrictions like maxlength, type, format etc. All that is described in schema itself. Schema sample attached.

Now, I generate a C# class out of this schema using XSD.exe or XSDGen tool. They do create a class but none of them incorporates the restrictions (validation) specified in schema. Basically, I want object class to have a way to validate those restrictions.

How can I generate a class from schema which also includes the restriction on fields?

Thanks
Pankaj

Here is the schema sample ---

<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<xsd:simpletype name="ssnumber" final="restriction">
<xsd:restriction base="xsd:string">
<xsd:length value="11" />
<xsd:pattern value="\d{3}\-\d{2}\-\d{4}" />
</xsd:restriction>
</xsd:simpletype>
<xsd:element name="Employee">
<xsd:complextype>
<xsd:sequence>
<xsd:element name="SSN" type="ssnumber" />
<xsd:element name="Name" type="xsd:string" />
</xsd:sequence>
</xsd:complextype>
</xsd:element>
</xsd:schema>

Any way you like. Are your products in different departments? Or come from different vendors?

They are from Different vendors but most of them have same XML structure with same parent tags ie catalog and product. under product there could be different number of values but overall structure is same.

any ideas ?

Best regards

how to make objects are visble/invisble..

26-Feb-09 3:28

I was hinting that you could make separate files for each department or vendor.

I wrote a simple code for help

Bitmap b1 = new Bitmap(256, 256);
Bitmap b2 = new Bitmap(256, 256);
Bitmap final = new Bitmap(256, 256);
Graphics g = Graphics.FromImage(b1);
g.DrawRectangle(Pens.Red, 0, 0, 150, 150);
g.Dispose();
g = Graphics.FromImage(b2);
g.DrawEllipse(Pens.Black, 100, 100, 50, 50);
g.Dispose();
g = Graphics.FromImage(final);
g.DrawImage(b1, new Point(0, 0)); // Delete this line if you dont want to draw b1 image
g.DrawImage(b2, new Point(0, 0));
g.Dispose();
pictureBox1.BackgroundImage = final;

Folder Lock and Hiding.

Hi,

I am trying to create a tool using c# which hides and locks folders similar to LockBox. This means that the hidden folder will be invisible to EVERYONE when protected, and visible when a password is entered. In code project there is an example using windows shell folders which actually "locks" the folder - but the problem is that it still is 1) Visible and 2) accessable through windows command prompt.

Thanks a lot Smile | :)

Ups ... you're right... I was just last in thinking lol..

So the question is. Is there anyway to do this in C# without using the mentioned methods above in my first post?

Looping though Dataset

I have a boolean value in a dataset bound to a checkbox control

If the user clicks on the checkbox I want to loop through the dataset and set the boolean to false for all other rows. In other words only one of the rows in the dataset/databinding can have the boolean field set to true.

How can I achieve this please?

I had thought to use something like:

foreach (DebtorDataSet.GuarantorRow grow in DebtorDataSet.Guarantor.Rows)
{
test this row against the current databinding.position/current somehow and set the boolean for this row accordingly
}

Not sure how to actually implement it though Blush | :O

DataSet never have Rows... what is DebtorDataSet.GuarantorRow WTF | :WTF:

My apologies. It is a datatable which is part of a dataset.

Just a suggestion, the functionality you mentioned is more of a radiobutton kind. Generally, checkbox is used to enable multiple selection and it could be misleading to use it for the usecase.

As I already said, it's just a suggestion Smile | :)

I agree that a radio button would make more sense, but I have to use a checkbox to fit in with the rest of my project. Any thoughts on how to go about it please?
