How to Change Folder Background Win7

1. First we have to unhide the protected operating system files.
   Goto any folder.
   Then Organize --> Folder and Search Options --> View (second tab)
   Select "Show hidden files, folders and drivers".
   then uncheck "Hide protected operating system files (Recommended)".
    
2. Then a file called "desktop.ini" will visible (that file may not be there too). If the "desktop.ini" is not at there then you will have to create it by yourself (just create a file and rename it to "desktop.ini" ).
    
3. Then enter the following code to the "desktop.ini" file.
   [AveFolder]
   IconArea_Image=E:\images\listening_music-1366x768.jpg

1. At that code " E:\images\listening_music-1366x768.jpg" is the the path & the name of the image you are going to set as your folder background.
    
2. After applying the image your folder names may not be clearly visible for you. So you can change the folder font color by adding the following code for the "desktop.ini" file (you can change the color by changing the TestR, TextG and TextB values. given values are the corresponding values for WHITE).
   TextR=255
   TextG=255
   TextB=255

1. Furthermore you can enable the "shadow text" feature by adding the following code to "desktop.ini" file.
   ShadowedText=1
    

That is how it happens and now you are OK... :D :D

Good luck....!!

How to download Oracle ADF tables in PDF format

          At this task we are going to convert ADF BC tables into PDF files and make it downloadable to users. It looks like very easy but it is not. To successfully complete this task I had to use several libraries such as apache fop library.
 

• What is Apache FOP library.....??

          FOP stands for Formatting Object Processor. Apache FOP is a Java application which reads a Formatting Object (FO) tree and renders the resulting pages to a specific output. Currently supported outputs are:

           PDF, PS, PCL, AFP, XML, Print, AWT and PNG, and to a lesser extend RFT and TXT.

          Developers use Apache FOP libraries to change the output file format very commonly because it’s free and open source. You can download the Apache FOP library as a JAR file from the below link. (There are different links to download FOP.jar; but most of the jar files do not contain all the libraries required for this conversion.)

[http://apache.deathculture.net/xmlgraphics/fop/binaries/fop-1.0-bin.zip]

•  How to convert ADF BC tables into PDF files

           If we try to analyse the process goes here we can simply represent it as below.

          First of all we want to get the table data and write it into a XML file. We can do it through JDeveloper framework. There is an inbuilt method called “printXML” at ViewObjectImpl class. It will generate the XML to the VO data. So if we can access the ViewObjectImpl class anyway we can generate the XML file. <VO>Impl class is a one which extends the ViewObjectImpl class. So we can generate the <VO>Impl class and generate the XML file.

• Implement the <VO>Impl and <Application_Module>Impl classes for your MODEL project. (We need those method at those classes to generate the XML file.)
  (<VO>.xml à Java à Java Classes à click on "pencil" icon.)

• Create a Java class at “View Controller” project to create a managed-bean. We are going to do all the coding inside this bean. All the required codes are mentioned at the end of this article.
   
• We can access the <VO>Impl class through this path:
  (FacesContext à ExternalContext à AdfFacesContext à HttpServletRequest à BindingContext à DCDataControl à ApplicationModule à AppModuleImpl à ViewObjectImpl)
   
• When we are creating the Node object we have two options. You can select the one which suits your requirement. (refer code while "// Print the XML" )
  

  Parameter	Description
  XML_OPT_ALL_ROWS	All rows will be rendered in XML
  XML_OPT_ASSOC_CONSISTENT	attribute accessors that return a RowSet should set the AssociationConsistent flag on, so that new (unposted) rows for the RowSet are also included in the output.
  XML_OPT_CHANGES_ONLY	For internal framework use only.
  XML_OPT_LIMIT_RANGE	Rows in the current range will be rendered in XML

  
  
• Then we have to generate the PDF using  a style sheet. Before genarate PDF files you should have to build the style sheet. Then we can generate the output file using FOP libraries (we can select the output format). Output format depends on the MimeConstant you select. There are several output formats supported by FOP libraries as follows. (refer code while "// Generate PDF" )
  
  

  MIME Constant	Output Format
  MIME_PDF	pdf
  MIME_PLAIN_TEXT	txt
  MIME_PNG	png
  MIME_FOP_AREA_TREE	xml
  MIME_POSTSCRIPT	ps
  MIME_AFP	afp
  MIME_TIFF	tiff

  
• Then insert a Command Button next to your ADF BC table. Create a web page backing bean and write an Action Method. Then set that action method as the “action” property of the created command button. Inside the action method we have to write some codes which will make the generated pdf file to be downloadable.
   
• When user press the command button pdf file shold be generated and downloadable. To do that  we have to go through the Context layers of the framework, get the http servlet response and set the content type of the response.
   
• Here we have set the content type as “application/pdf” because we have generated a pdf file. That parameter depends on your file type. (refer code while "// download the PDF" )
  
    

All the required codes are given below.....

 

// Access the <VO>Impl

FacesContext facesContext = FacesContext.getCurrentInstance();

ExternalContext externalContext = facesContext.getExternalContext();

AdfFacesContext context = AdfFacesContext.getCurrentInstance();

HttpServletRequest request = (HttpServletRequest)FacesContext.getCurrentInstance().getExternalContext().getRequest();

BindingContext ctx = DCUtil.getBindingContext(request);

DCDataControl dc = ctx.findDataControl("AppModuleDataControl");

ApplicationModule service = (ApplicationModule)dc.getDataProvider();

ApplicationModule am = service.findApplicationModule("AppModule");

AppModuleImpl amImpl = (AppModuleImpl)am;

ViewObjectImpl VOImlp = (EmpVOImpl)amImpl.findViewObject("EmpVO1");

HashMap viewDefMap = new HashMap();

// Print the XML

Node n = VOImlp.writeXML(XMLInterface.XML_OPT_ALL_ROWS, viewDefMap);

java.io.File file = new java.io.File(<path to save XML file>);

PrintWriter output = null;

try {  output = new java.io.PrintWriter(file);

          ((XMLNode)n).print(output);

} catch (Exception e) { System.out.println(e.getMessage());

} finally {

try {output.close(); } catch (Exception e) { System.out.println(e.getMessage()); } } }

// Generate PDF

File xmlfile = new File(<path to generated XML file>);

File xsltfile = new File(<path to styleSheet>);

File pdffile = new File(<path to save PDF file>);

FopFactory fopFactory = FopFactory.newInstance();

FOUserAgent foUserAgent = fopFactory.newFOUserAgent();

OutputStream out = new java.io.FileOutputStream(pdffile);

out = new java.io.BufferedOutputStream(out);

try {

Fop fop = fopFactory.newFop(MimeConstants.MIME_PDF, foUserAgent, out);

TransformerFactory factory = new TransformerFactoryImpl();

Transformer transformer = factory.newTransformer(new StreamSource(xsltfile));

transformer.setParameter("versionParam", "2.0");

Source src = new StreamSource(xmlfile);

Result res = new SAXResult(fop.getDefaultHandler());

transformer.transform(src, res);

} finally { out.close(); }

// download the PDF

FacesContext facesContext = FacesContext.getCurrentInstance();

ExternalContext externalContext = facesContext.getExternalContext();

HttpServletResponse response = (HttpServletResponse)externalContext.getResponse();

File file = new File(dir1, pdffile1);

BufferedInputStream input = null;

BufferedOutputStream output = null;

try {

input = new BufferedInputStream(new FileInputStream(file), DEFAULT_BUFFER_SIZE);

          response.reset();

          response.setContentType("application/pdf");

          response.setContentLength((int)file.length());

response.setHeader("Content-disposition","inline;filename=\""+pdffile1+"\"");

output = new BufferedOutputStream(response.getOutputStream(),DEFAULT_BUFFER_SIZE);

          byte[] buffer = new byte[DEFAULT_BUFFER_SIZE];

          int length;

          while ((length = input.read(buffer)) > 0) {

              output.write(buffer, 0, length); }

          output.flush(); } finally { close(output); close(input); }

facesContext.responseComplete();

      

CHEERS.......!!
