yes, but how will I implement it by not touching any of the MyModule code? I only want to add to the configuration file, so each time I add a vendor I don't have to change the code
Can you please provide a code so that I'll know if what you're suggesting is feasible on my part?

Simply set the number of vendors in you configuration file and then create an array of vendors with the required size at runtime.

Is this how you're suggesting it?
public struct Example1
{
public int Vendor1;
public int Vendor2;
public int vendorcount =2;
}
class MyModule
{
int[] newint = new int[vendorcount];
for(int x=1; x<vendorcount;x++)>
{
newint[x] = Exmaple1.Vendor1; ,--- (PROBLEM) how to point to Vendor2, vendor 3
}
}
how will be able to iterate through Vendor1 to Vendor2 (to vendor3 and so forth)? If I do this I'll have to change code on the MyModule class. I need to avoid having to change the code each time I add a new vendor
|
|
|
|
|
Nope.
I mean something similar to
class Example
{
public Example(int count){ vendor = new Vendor[count];}
public Vendor[] vendor;
};
class Program
{
public static void Main()
{
Example example = new Example(vendorCount);
}
}

Hi,
Any clean idea on how to load a tree-like structure "eg. nested folders" into a treeview control?? I know I have to use recursion but I dont have the guts to do it 
Please, shed some light on me if you have a previous experience in such problem.
Thanks guys!
To define recursion, we must first define recursion!

if (!listBox1.Items.Contains(subFile))
listBox1.Items.Add(subFile);
else

I think I have the guts to do it after all 
C'mon, give me five

Hi ,
I create a xml string using a xmldocument (c# 2.0 )
This is my code (more or less)
XmlElement MySearchNode = xmlDoc.CreateElement("MySearch");
xmlDoc.AppendChild(MySearchNode);
...
XmlNode node1 = xmlDoc.SelectSingleNode("/MySearch/Objects");
XmlAttribute nameAttrib = xmlDoc.CreateAttribute("result");
nameAttrib.Value = "012";
node1.Attributes.Append(nameAttrib);
xmlDoc.outerxml
I want to validate the xml string against a XSD :
XmlReader rdr = null;
XmlParserContext context = new XmlParserContext(null, null, "", XmlSpace.None);
XmlTextReader readerXml = new XmlTextReader(p_xml, XmlNodeType.Element, context);
XmlTextReader readerSchema = new XmlTextReader(p_xsdPath);
XmlSchema schema = new XmlSchema();
schema = XmlSchema.Read(readerSchema, new
ValidationEventHandler(Schema_ValidationEventHandler));
XmlReaderSettings ReaderSettings = new XmlReaderSettings();
ReaderSettings.ValidationType = ValidationType.Schema;
ReaderSettings.Schemas.Add(schema);
ReaderSettings.ConformanceLevel = ConformanceLevel.Fragment;
ReaderSettings.ValidationEventHandler += new
ValidationEventHandler(settings_ValidationEventHandler);
rdr = XmlReader.Create(readerXml, ReaderSettings);
this is my XSD
(a part of it)
<?xml version="1.0" encoding="utf-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="MySearch">
<xs:complexType>
<xs:sequence>
<xs:element name="Objects" type="tObjects" minOccurs="0" maxOccurs="1" />
</xs:sequence>
<xs:attribute name="result" type="xs:string" />
</xs:complexType>
</xs:element>
<xs:complexType name="tObjects">
<xs:sequence>
<xs:element name="House" type="tHouse" minOccurs="0" maxOccurs="unbounded">
</xs:element>
<xs:element name="Garden" type="tGarden" minOccurs="0" maxOccurs="unbounded" />
</xs:sequence>
</xs:complexType>
....
Note : this is my xml string
<MySearch>
<Objects result = '012' >
<House>
...
</House>
</Objects>
</MySearch>
when I validate I get this error :
The 'result' attribute is not declared.
I see that validation process need :
ReaderSettings.ValidationFlags = XmlSchemaValidationFlags.AllowXmlAttributes;
and
attributeFormDefault="unqualified" .
It doesn't work !!  I always get the same error ..
Could you help me ? thanks in advance .

I have heard that .NET framework is redistributable..
Does it mean that it is free??
If I build a client application in .NET, certainly I would need the framework, that why I want to know that can I install it in the clients system without any licensing hassles??
Are all latest frameworks free or the only the old ones? (upto 2.0) ??
|
|
|
|
|
Yes, all versions (so far) are free. I believe that framework 2 is usually included with Vista - I don't run Vista so I'm not sure.

So what is the Difference between .NET framework 3.0 and .NET framework 3.0 redistributable package??
|
|

One is the whole framework, which is free, and can be used to write apps, even without visual studio. The other is just the bit the end user needs to run your code.
There is a free IDE as well, so I don't think many people use just the free framework anymore.

Now this is very interesting..
Culd you please elaborate more on this?
How can I write apps in .NET framework without Visual Studio??
Do I have to use an editor of some other vendor for this?

Sharpdevelop [^] is an open source IDE.
BTW Visual C# Express Edition [^] is free.

I used SharpDevelop in College...
*Shudders*
Visual C# Express Edition or Notepad :p (Or preferably EditPad Lite instead of Notepad, but that's just me...  )
|
|

I fully disagree : I used Sharpdevelop (only a bit, I admit) and like it.
Visual C# Express Edition is great value for money (BTW Notepad++ is much better than Notepad).

Great value for money... Lol :p
And my response with my SharpDevelop experience might be directly related to the fact that I was using it in 2005, when it was still in Beta....

Is Visual Studio still in beta or am I wrong?

You may use Notepad if you wish. The compiler is a free download.

Hello everyone,
I am confused after reading the exitContext parameter from MSDN,
http://msdn2.microsoft.com/en-us/library/kzy257t0(VS.80).aspx
What does the context mean? Does it mean if I acquire some lock (e.g. lock, readwrite lock, monitor) before invoking WaitOne, then when calling WaitOne, the locks are automatically released?
So, when the thread is waking up again by signal from WaitOne or timeout from WaitOne, it will have to try to acquire the lock or locks again before execution?
thanks in advance,
George
