The string that you have mentioned is nothing but XML String. So My suggestion is that please don't thing about to use String Manipulation Or Regx to get the particular value.

So, what you can is, convert the XML string to XMLDocument and easily use XPath to find out the value of particular tag :

Here is one sample example :

XPathDocument Xdoc = new XPathDocument(XMLFile);
XPathNavigator Xnav = Xdoc.CreateNavigator();
XPathExpression expression; 
expression= nav.Compile("/Parameters/Parameter/Name");
XPathNodeIterator Xiterator = Xnav.Select(expr);

Now using Xiterator, you can easily get the value Smile | :)

.

This will help you for all kind of search over the XML String.

Let me if you have any doubts regarding the same.

Thanks !!

You Can Do Easily with the help of Xml..!
You ask the same question in c# ..!So i am Giving it in C#.net with windows..!
Use the code below

string XML = "   <Parameters>    <UserProfileState>0</UserProfileState>    <Parameter>      <Name>dbname</Name>      <Type>String</Type>      <Nullable>False</Nullable>      <AllowBlank>False</AllowBlank>      <MultiValue>False</MultiValue>      <UsedInQuery>True</UsedInQuery>      <State>MissingValidValue</State>      <Prompt>dbname</Prompt>      <DynamicPrompt>False</DynamicPrompt>      <PromptUser>True</PromptUser>    </Parameter>  </Parameters>";
            System.Xml.XmlDocument Document = new XmlDocument();
            Document.LoadXml(XML);

            foreach (XmlNode n in Document. SelectSingleNode  ("Parameters/Parameter/Name").ChildNodes )
            {

                MessageBox.Show(n.InnerText);

              
            }

Hope you have already designed the SSRS reports and hosted the same on IIS Server.

Now you need to do the following steps .
First : Add Microsoft.Reporting.WebForms namespace with your ASP.NET Web application . This contains methods and properties for the ReportViewer Web server control.

<%@ Register Assembly="Microsoft.ReportViewer.WebForms  Namespace="Microsoft.Reporting.WebForms" TagPrefix="SSRSWeb" %>

Second : SSRS viewer assembly will add the ReportViewer control with your web application which you can use to featch the data from SSRS to your aspx page.

<SSRSWeb:ReportViewer runat="server"  Width="500px" Height="700px" ID="SSRSViewer">
        </SSRSWeb:ReportViewer>

Third : Add Button Click Code Behind For view the Reports

SSRSViewer.ProcessingMode = Microsoft.Reporting.WebForms.ProcessingMode.Remote;
    SSRSViewer.ServerReport.ReportPath = "MyReports";
SSRSViewer.ServerReport.ReportServerUrl = new Uri("http://localhost/ssrsreports");

You are done !!

You are talking for ASP.NET web application connection string or what ? I guess you need to change only in config file. Nothing else.

Use Report Viewer and display tha report in reportViewer..!
here is the sample code which i done previously

  DataView dv = new DataView();
 //Accessing the Method From Class File
 dv = dAccess.GetDataView();
//Calling the Method
 ReportDisplay(dv);

       private void ReportDisplay(DataView dv)
            {
            // Set RDL file
            reportViewer.LocalReport.ReportPath = "Report.rdlc";
            // Supply data corresponding to each report data source.
            reportViewer.LocalReport.DataSources.Add(new      ReportDataSource("AdventureWorksDataSet_CreditCard", dv));
             // Process and render the report
             reportViewer.LocalReport.Refresh();
}

If You have Any More Doubts in ssrs reports Feel Free to ask me..!

Hi Dharam,
This is quite general scenario where we need to create aspx page at runtime from xml.

Below are the few steps that you need to follow.

Step 1 : Create XML as per requirement of Page . That you are already defined.

Here along with Control Type and name you can also define all other properties. I will suggest you to use different property tag for controls for easily understanding.

Step 2 : Create XSLT style to transform our XML schema

You need to create XSLT in the way where you can iterate through each and every propery of an control.

Note : Using XSLT you can also mention the validation control too.

Step 3 : Now using Code behind Transform XML using XmlDocumentand XslTransform

Step 4: Finally Add the output result in page control hierarchy

Control Pagectrl = Page.ParseControl(OutPut);
Page.Controls.Add(Pagectrl);

Hope this will help you to move ahead.

Thanks !

Visual Web Studio or Dreamweaver for website layout/design?

James Shao3-Dec-09 12:14

James Shao

I am relatively new to website design and programming and have been learning both for the past few months. While ASP.Net is awesome, I feel that in terms of website layout and design, Dreamweaver CS4 is superior to Visual Web Studio 2008. I could create a simple but great looking website using Dreamweaver within half an hour, yet find it a bit more difficult to do so using Visual Web Studio (things just don't seem to fall in the right places). Roll eyes | :rolleyes:

What do you guys think?

How about designing the general layout and master page using Dreamweaver, and then put in all the controls/programming in Visual Web Studio?

It depends on your preference. Whatever you do, the resultant html should be neat, simple and follows all necessary standards.

Dreamweaver is only for UI designing while VS is designed for multipurpose. So you won't get all the luxury in VS which you have in Dreamweaver. One possible thing is to design the webpage on dreamweaver (or whatever editor you like) and copy the HTML to VS.

Javascript in HTML interacting with PDF Javascript

Ennis Ray Lynch, Jr.3-Dec-09 8:10

Ennis Ray Lynch, Jr.

3-Dec-09 8:10

I am tasked with discovering a way to programmatically (with HTML and Javascript) interact with an Adobe PDF file and potentially calling JavaScript within the PDF in an Adobe Reader control. I need to find specific documentation either stating the complete how's, in's and out's or an Adobe publication stating that it cannot be done. Unfortunately, the specific keywords involved make Google searching difficult and I have not found Adobe's site particularly helpful. Also, to make this even more interesting, this needs to be done without Reader Extensions so hacking it to use Web Service listeners and callbacks is out, AIR is out, and Flex is out.

Need custom software developed? I do custom programming based primarily on MS tools with an emphasis on C# development and consulting.

Creating HTML Page with XSLT and XML

I want to create a HTML page using XML and XSLT but I need to collect an image from the XML file (embedded) and translate it to the XSLT page for include it in the page, any suggestion about how to do it ?

Best Regards

XSLT is used to have output based on data passed through xml. If you want to show an image, either place the url of the image embedded within the xml or create image in the server and modify xml with appropriate path.

You might also consider to directly write the base64 stream in source of img tag, but it doesnt work in most of the browser nowadays.
<img src="data:image/gif;base64,DASD234AFD+" />

I dont explain it enough, I have just the image embedded in the XML document, but now I am processing the XML document containing the image with an XSLT stylesheet for creating an HTML page and I want that this page shows the image, so I know that I need:

1) Recover the image from the XML (with binary reader).
2) recover the image in memory (not problem a memoryStream and a BitMap object)
3) send the content of the bitmap to the XSLT stylesheet for include in the HTML page ( this I dont know How).

Best Regards

Abhishek Sur3-Dec-09 23:38

Yes.. I got your point.

First of all, XSLT is processed in browser. You just do the logic how the html will be generated and pass the XML. There is no option to generate an image in the browser in XSLT.

If you are going to use embedded image in xml, you need to either transform them in server side to produce image and replace the image path in xml and generate html from that xml... or embed the base64 directly in img src as I mentioned.

I think the first option is good, you need to store the embedded data with image source in the xml before you add xml transformation.

If I was in your situation, I would have used Repeater directly, rather than depend so much in browser using XSLT. Repeater is always better to handle your html as you are sure what you are generating from the server side. You can use OnItemDataBound event to store the image (or directly put in response) and add it to src.

Anyways, you should better choose what suits you. But somehow you have to change the embedded base64 stream to proper image data. Rose | [Rose]

Really Abhishek, No option to recover the image at client level, so I know that I need to use an binary Reader to recover the Image from the XML file, and store the data in a Stream, later I have two options, save the data to a file using a FileStream, but it's not a good option to save data in client hard disk, so there is also one option of creating a Bitmap object in memory because this object, accepts a stream as data origen, but later I don´t know how to point to the bitmap from the xls, because the image src parameter allways look for a string and not any other object.

I think that this functionality must be very frecuent in News Web Pages which receive a XML with data and Photo and inmediately process them, you told me about an repeater object, I'm going to analyze such possibility.

Best Regards

Yes...
Another thing that I need to address, images are actually called as a new Request. So for every image request, IIS will spawn a new thread from its ThreadPool and create a Response.

If you can, you can just put the image data into the database or some storage and pass the id to the xml. Create one HttpHandler which will request the image with the id. Say your httphandler is ImageResource.axd.

you write using xslt as :

<img src="ImageResource.axd?id=59" /><br />

Now within the ProcessRequest, write the image data directly in the response stream.

This might be one useful way.

Also it is impossible to store image directly to client hard disk because of security issue in browser. What you can do, is place some Cache headers to the response, and the browser will automatically cache the image to its local storage and will not call the server again if the same resource is called for again.

Cheers.
