Set Priority = System.Net.Mail.MailPriority.Normal as the default and use it regardless of whether the user sets it differently.

Another way you could handle this situation is to not have priority as a property but as an optional parameter for the method or function that ends up actually sending the email. Optional parms have to the last parms of the method and have to have a default set. The method header would look something like this:

Public SendMyEmail(ByVal strEmailMessage as String, Optional ByVal strPriority as System.Net.Mail.MailPriority = Net.Mail.MailPriority.Normal)

(Of course, you would probably have a number of other parms before the optional one like who the email is to be sent to, from, CC, BCC, and so on.)

Hope this gives you some ideas to work from.

Use the page's RenderControl method:

System.Text.StringBuilder builder = new System.Text.StringBuilder();<br />
System.IO.StringWriter writer = new System.IO.StringWriter(builder);<br />
HtmlTextWriter html = new HtmlTextWriter(writer);<br />
RenderControl(html);

This places the page's HTML into the StringBuilder variable, builder. The string can then be set as the body of your email message. Please note, however, that if there are any relative references (such as to a style sheet or an image or a link to another page) you will need to convert them to fully qualified URLS.

ASP.NET provides just the framework to provide a web interface for your application. Your application is written in C#, the language, which is independent of how the application presents itself to the outside world.

If you have designed your application properly by separating out the presentation layer from the business logic and database layers then it should be easy to replace the front end your application currently has with an ASP.NET front end.

The bottom line is that you will have to write some ASP.NET code, but this will be in addition to what is already there.

If you have designed your application badly then you will have to re-write it and no one can help you with that.

Thanx for your response , I believe the application is written in a good structure , UI is seperate from the business logic because it already written for two user langauges with same functions on same froms , just the UI can be swaped ( Hot swap ) while the application is running to show english language UI Or right side language UI . events in all controls do not contain business code , they tend to call functions or methods carrying that code , no control event holds more than one line of code .

May be the reason of my quastion is that I am starting web applications for the first time with ASP.NET .

By this mean, if you use the file:/// protocol for the images in the web page, then the web page also needs to be viewed with this protocol in FF (though IE works just fine in this case). If you view the web page starting with http:// .. then the url of the images need to be set with http.

Help with reading XML with C#

robert11027-Sep-06 4:34

27-Sep-06 4:34

Hello everyone:

I am struggling with XML (which I am really not good at), the file that I am working with is something like this:

<MotherCompany Name="MC">
 <Company Name="CompanyOne">
    <Department>
     <IsPositions>
        <Temp>
            <MoreNestedDetails></MoreNestedDetails>
        </Temp>
        <IsPerm>
            <MoreNestedDetails></MoreNestedDetails>
        </IsPerm>
        <Intern>
            <MoreNestedDetails></MoreNestedDetails>
        </Intern>
        <Other>
            <MoreNestedDetails></MoreNestedDetails>
        </Other>
      </IsPositions>
    </Department>
 </CompanyOne>
 <Company Name="CompanyTwo">
    <Department>
     <IsPositions>
        <Temp>
            <MoreNestedDetails></MoreNestedDetails>
        </Temp>
        <IsPerm>
            <MoreNestedDetails></MoreNestedDetails>
        </IsPerm>
        <Intern>
            <MoreNestedDetails></MoreNestedDetails>
        </Intern>
        <Other>
            <MoreNestedDetails></MoreNestedDetails>
        </Other>
      </IsPositions>
    </Department>
 </CompanyTwo>
 <Company Name="CompanyThree">
    <Department>
     <IsPositions>
        <Temp>
            <MoreNestedDetails></MoreNestedDetails>
        </Temp>
        <IsPerm>
            <MoreNestedDetails></MoreNestedDetails>
        </IsPerm>
        <Intern>
            <MoreNestedDetails></MoreNestedDetails>
        </Intern>
        <Other>
            <MoreNestedDetails></MoreNestedDetails>
        </Other>
      </IsPositions>
    </Department>
 </CompanyThree>
 <Company Name="CompanyFour">
    <Department>
     <IsPositions>
        <Temp>
            <MoreNestedDetails></MoreNestedDetails>
        </Temp>
        <IsPerm>
            <MoreNestedDetails></MoreNestedDetails>
        </IsPerm>
        <Intern>
            <MoreNestedDetails></MoreNestedDetails>
        </Intern>
        <Other>
            <MoreNestedDetails></MoreNestedDetails>
        </Other>
      </IsPositions>
    </Department>
 </CompanyFour>
</MotherCompany>

Now what I need to do is read the information for each Company under MotherCompany.

A - Since its so freaking nested I am confused as to how to go about collecting the information. Any ideas and suggestion?

B - I tried to use XMLReader; I was doing something like:

<br />
XmlTextReader reader = new XmlTextReader(FileNameWithPath);  <br />
while (reader.Read())<br />
{<br />
  if (reader.Name == "Company")<br />
  {<br />
    if (reader.NodeType == XmlNodeType.Element)<br />
    {<br />
      XmlReader currentNode = reader.ReadSubtree();<br />
      while (currentNode.Read())<br />
      {<br />
        if (currentNode.NodeType == XmlNodeType.Element)<br />
        {<br />
          switch (currentNode.Name)<br />
           {<br />
          case "Temp<br />
            dataCol.MethodList.Add(currentNode.Name);<br />
            break;<br />
          case "IsPerm<br />
            dataCol.MethodList.Add(currentNode.Name);<br />
            break;<br />
          case "Intern<br />
            dataCol.MethodList.Add(currentNode.Name);<br />
            break;<br />
          case "Other<br />
            dataCol.MethodList.Add(currentNode.Name);<br />
            break;<br />
          default:<br />
            break;<br />
          }<br />
        }<br />
      }<br />
    }<br />
  }<br />
}<br />

First of all my reader.ReadSubtree(); reads all the Company Elements, I thought that it would read any thing within the Company Element so I would be able to get data for seperate Company Elements depending on thier the Name attribute. How can I do that in the given scenario? Is there a better way? Like somehow skip to the elements that I need instead of worrying about the nested loops and crap?

Any help will be great and HIGHLY appreciated. Thanks.

PS: At some point I will need to go and get more details and it looks like I am keep nesting while loops for every detailed value; is there a better way of doing that?

Use XPathDocument or XmlDocument instead of the XmlTextReader, unless this is a really huge file.

XPathDocument doc = new XPathDocument("MyFile.xml");<br />
XPathNavigator nav = doc.CreateNavigator();<br />
<br />
XPathNodeIterator nodes = nav.Select("//Company");

Now you should have a collection of Company nodes to iterate through

Mark:

Thanks a lot for your suggestion. This document is typically more then 500 lines but the Company Nodes are not the one that increase the file size, its other junk thats embeded in it. Do you think it would be ok to use XPathDocument for such size files?

Thanks.

It should be fine as long as the file size isn't more than say 1mb

Well just came to find out that the file I've been working with is not an xml file instead it is an xsd file Confused | :confused:

This will explain why xmlreader was working by xpath logic was not working (yeah it was looping thorugh all the elements Blush | :O

).

Any suggestions?

robert11027-Sep-06 16:06

XPathDocument doc = new XPathDocument(FileNameWithPath);
XPathNavigator nav = doc.CreateNavigator();
XPathNodeIterator nodes = nav.Select("/MotherCompany/Compant/Department/IsPositions");
//string x = nodes.Current.GetAttribute("Name", nodes.Current.NamespaceURI);
XPathNavigator nodesNav = nodes.Current;
XPathNodeIterator ni = nodesNav.SelectDescendants(XPathNodeType.Element, false);
while(nodes.MoveNext())
{
    MessageBox.Show(nodes.Current.Name);
    //nodes.Current.GetAttribute("Name",nodes.Current.NamespaceURI);
        // MessageBox.Show(ni.Current.Name + "\n" + ni.Current.Value);
        richTextBox1.AppendText(Environment.NewLine
            + "Name:" + /*x +*/ Environment.NewLine
            + nodes.Current.Name + Environment.NewLine +
            nodes.Current.Value
            );
}

When I look in the debug mode to see what is going; this is what I get for my ni Position=0, Current={Root}, Count=0
And aparently nothing happends...
Can someone please help me read this document? I sure would appreciate it. Thanks.

XPathNodeIterator nodes = nav.Select("/MotherCompany/Compant/Department/IsPositions");
nodes.MoveNext();
XPathNavigator nodesNav = nodes.Current;

The iterator is not positioned at the start so you must move to an element before accessing anything.

Thanks for your help and patience with me Mark. However I still dont get any thing even after putting nodes.MoveNext().

Do you think that <xs:schema>, <xs:annotation>, <xs:appinfo> (which are at the top of the document and <MotherCompany> is nested within <xs:appinfo> ) has anything to do with it?

Appreciate your help.

Robert
