I want to retrieve image from access database and want to show it on jlabel in netbeans. I've searched a lot on Google but I couldn't find the code fo retrieving image from MS Access. Can anyone help me in this matter please? I wrote the following code but it is not working. It's giving me the error
Record not found
DbConn obj = new DbConn();
String PatientID = getPid().getText();
String query = "Select [PatientEarImage] from PatientRecord where PatientID='"+PatientID+"'";
ResultSet rs= obj.Search(query);
try
{
while(rs.next())
{
byte[] img = rs.getBytes("PatientEarImage");
ImageIcon immgg;
immgg = new ImageIcon();
Image im = immgg.getImage();
Image myImg= im.getScaledInstance(getUpload().getWidth(), getUpload().getHeight(), Image.SCALE_SMOOTH);
ImageIcon newImage = new ImageIcon("PatientEarImage.jpg");
upload.setIcon(newImage);
}
}
catch (Exception ex)
{
ex.printStackTrace();
JOptionPane.showMessageDialog(null, "No Record Found");
}
Try this codes. I'm also used MS Access Database as a backend database
Blob filenameBlob = rs.getBlob("picture");
byte[] content = filenameBlob.getBytes(1L, (int) filenameBlob.length());
ImageIcon AA = new ImageIcon(content);
Image BB = AA.getImage();
Image CC = BB.getScaledInstance(FRAMEBOXPIC.getWidth(), FRAMEBOXPIC.getHeight(),
java.awt.Image.SCALE_SMOOTH);
AA = new ImageIcon(CC);
FRAMEBOXPIC.setIcon(AA);

I have to put my list data in a table in a pdf file. My data has some Arabic words. When my pdf is generated, the Arabic words don't appear. I searched and found that I need itext7.pdfcalligraph so I installed it in my app. I found this code too https://itextpdf.com/en/blog/technical-notes/displaying-text-different-languages-single-pdf-document and tried to do something similar to allow Arabic words in my table but I couldn't figure it out.
This is a trial code before I apply it to my real list:
var path2 = global::Android.OS.Environment.ExternalStorageDirectory.AbsolutePath;
filePath = System.IO.Path.Combine(path2.ToString(), "myfile2.pdf");
stream = new FileStream(filePath, FileMode.Create);
PdfWriter writer = new PdfWriter(stream);
PdfDocument pdf2 = new iText.Kernel.Pdf.PdfDocument(writer);
Document document = new Document(pdf2, PageSize.A4);
FontSet set = new FontSet();
set.AddFont("ARIAL.TTF");
document.SetFontProvider(new FontProvider(set));
document.SetProperty(Property.FONT, "Arial");
string[] sources = new string[] { "يوم","شهر 2020" };
iText.Layout.Element.Table table = new iText.Layout.Element.Table(2, false);
foreach (string source in sources)
{
Paragraph paragraph = new Paragraph();
Bidi bidi = new Bidi(source, Bidi.DirectionDefaultLeftToRight);
if (bidi.BaseLevel != 0)
{
paragraph.SetTextAlignment(iText.Layout.Properties.TextAlignment.RIGHT);
}
paragraph.Add(source);
table.AddCell(new Cell(1, 1).SetTextAlignment(iText.Layout.Properties.TextAlignment.CENTER).Add(paragraph));
}
document.Add(table);
document.Close();
I updated my code and added the arial.ttf to my assets folder . i'm getting the following exception:
System.InvalidOperationException: 'FontProvider and FontSet are empty. Cannot resolve font family name (see ElementPropertyContainer#setFontFamily) without initialized FontProvider (see RootElement#setFontProvider).'
and I still can't figure it out. any ideas?
thanks in advance

I have a similar situation for Turkish characters, and I've followed these
steps :
Create a folder under projects root folder which is : /wwwroot/Fonts
Add OpenSans-Regular.ttf under the Fonts folder
Path for font is => ../wwwroot/Fonts/OpenSans-Regular.ttf
Create font like below :
public static PdfFont CreateOpenSansRegularFont()
{
var path = "{Your absolute path for FONT}";
return PdfFontFactory.CreateFont(path, PdfEncodings.IDENTITY_H, true);
}
and use it like :
paragraph.Add(source)
.SetFont(FontFactory.CreateOpenSansRegularFont()); //set font in here
table.AddCell(new Cell(1, 1)
.SetTextAlignment(iText.Layout.Properties.TextAlignment.CENTER)
.Add(paragraph));
This is how I used font factory for Turkish characters ex: "ü,i,ç,ş,ö"
For Xamarin-Android, you could try
string documentsPath = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);
var path = Path.Combine(documentsPath, "Fonts/Arial.ttf");
Look i fixed it in java,this may help you:
String font = "your Arabic font";
//the magic is in the next 4 lines:
PdfFontFactory.register(font);
FontProgram fontProgram = FontProgramFactory.createFont(font, true);
PdfFont f = PdfFontFactory.createFont(fontProgram, PdfEncodings.IDENTITY_H);
LanguageProcessor languageProcessor = new ArabicLigaturizer();
//and look here how i used setBaseDirection and don't use TextAlignment ,it will work without it
com.itextpdf.kernel.pdf.PdfDocument tempPdfDoc = new com.itextpdf.kernel.pdf.PdfDocument(new PdfReader(pdfFile.getPath()), TempWriter);
com.itextpdf.layout.Document TempDoc = new com.itextpdf.layout.Document(tempPdfDoc);
com.itextpdf.layout.element.Paragraph paragraph0 = new com.itextpdf.layout.element.Paragraph(languageProcessor.process("الاستماره الالكترونية--الاستماره الالكترونية--الاستماره الالكترونية--الاستماره الالكترونية"))
.setFont(f).setBaseDirection(BaseDirection.RIGHT_TO_LEFT)
.setFontSize(15);
I have been trying to convert XDP to PDF using Adobe Live Cycle. Most of my forms turn up good. But while converting some of them, I fine ??? replaced in place of blank spaces at certain places. Any suggestions to how can I rectify that?
Below is the code snippet that I am using:
public byte[] generatePDF(TextDocument xdpDocument) {
try {
Assert.notNull(xdpDocument, "XDP Document must be passed.");
Assert.hasLength(xdpDocument.getContent(), "XDPDocument content cannot be null");
// Create a ServiceClientFactory object
ServiceClientFactory myFactory = ServiceClientFactory.createInstance(createConnectionProperties());
// Create an OutputClient object
FormsServiceClient formsClient = new FormsServiceClient(myFactory);
formsClient.resetCache();
String text = xdpDocument.getContent();
String charSet = xdpDocument.getCharsetName();
if (charSet == null || charSet.trim().length() == 0) {
charSet = StandardCharsets.UTF_8.name();
}
byte[] bytes = text.getBytes();
ByteArrayInputStream byteArrayInputStream = new ByteArrayInputStream(bytes);
Document inTemplate = new Document(byteArrayInputStream);
// Set PDF run-time options
// Set rendering run-time options
RenderOptionsSpec renderOptionsSpec = new RenderOptionsSpec();
renderOptionsSpec.setLinearizedPDF(true);
renderOptionsSpec.setAcrobatVersion(AcrobatVersion.Acrobat_9);
PDFFormRenderSpec pdfFormRenderSpec = new PDFFormRenderSpec();
pdfFormRenderSpec.setGenerateServerAppearance(true);
pdfFormRenderSpec.setCharset("UTF8");
FormsResult formOut = formsClient.renderPDFForm2(inTemplate, null, pdfFormRenderSpec, null, null);
Document xfaPdfOutput = formOut.getOutputContent();
//If the input file is already static PDF, then below method will throw an exception - handle it
OutputClient outClient = new OutputClient(myFactory);
outClient.resetCache();
Document staticPdfOutput = outClient.transformPDF(xfaPdfOutput, TransformationFormat.PDF, null, null, null);
byte[] data = StreamIO.toBytes(staticPdfOutput.getInputStream());
return data;
} catch(IllegalArgumentException ex) {
logger.error("Input validation failed for generatePDF request " + ex.getMessage());
throw new EformsException(ErrorExceptionCode.INPUT_REQUIRED + " - " + ex.getMessage(), ErrorExceptionCode.INPUT_REQUIRED);
} catch (Exception e) {
logger.error("Exception occurred in Adobe Services while generating PDF from xdpDocument..", e);
throw new EformsException(ErrorExceptionCode.PDF_XDP_CONVERSION_EXCEPTION, e);
}
}
I suggest trying 2 things:
Check the font. Switch to something very common like Arial / Times New Roman and see if the characters are still lost
Check the character encoding. It might not be a simple question mark character you are using and if so the character encoding will be important. The easiest way is to make sure your question mark is ascii char 63 (decimal).
I hope that helps.
In a project I have to split a PDF document into two documents, one containing all blank pages, and one containing all pages with content.
For this job, I use a PdfReader to read the source file, and two pdfCopy objects (one for the blank pages document, one for the pages with content document) to write the files to.
I use GetImportedPage to read a PdfImportedPage, which is then added to one of the PdfCopy writers.
Now, the problem is the following: the source file is using the "tagged PDF format". To preserve this (which is absolutely required), I use the SetTagged() method on both PdfCopy writers, and use the extra third parameter in GetImportedPage(...) to keep the tagged format. However, when calling the AddPage(...) on the PdfCopy writer, I get an invalid cast exception:
"Unable to cast object of type 'iTextSharp.text.pdf.PdfDictionary' to type 'iTextSharp.text.pdf.PRIndirectReference'."
Anyone has any ideas on how to solve this ? Any hints ?
Also: the project currently refers version 5.1.0.0 of the itext libraries. In 5.4.4.0 the third parameter to GetImportedPage does not seem to be there anymore.
Below, you can find a code extract:
iTextSharp.text.Document targetPdf = new iTextSharp.text.Document();
iTextSharp.text.Document blankPdf = new iTextSharp.text.Document();
iTextSharp.text.pdf.PdfReader sourcePdfReader = new iTextSharp.text.pdf.PdfReader(inputFile);
iTextSharp.text.pdf.PdfCopy targetPdfWriter = new iTextSharp.text.pdf.PdfSmartCopy(targetPdf, new FileStream(outputFile, FileMode.Create));
iTextSharp.text.pdf.PdfCopy blankPdfWriter = new iTextSharp.text.pdf.PdfSmartCopy(blankPdf, new FileStream(blanksFile, FileMode.Append));
targetPdfWriter.SetTagged();
blankPdfWriter.SetTagged();
try
{
iTextSharp.text.pdf.PdfImportedPage page = null;
int n = sourcePdfReader.NumberOfPages;
targetPdf.Open();
blankPdf.Open();
blankPdf.Add(new iTextSharp.text.Phrase("This document contains the blank pages removed from " + inputFile));
blankPdf.NewPage();
for (int i = 1; i <= n; i++)
{
byte[] pageBytes = sourcePdfReader.GetPageContent(i);
string pageText = "";
iTextSharp.text.pdf.PRTokeniser token = new iTextSharp.text.pdf.PRTokeniser(new iTextSharp.text.pdf.RandomAccessFileOrArray(pageBytes));
while (token.NextToken())
{
if (token.TokenType == iTextSharp.text.pdf.PRTokeniser.TokType.STRING)
{
pageText += token.StringValue;
}
}
if (pageText.Length >= 15)
{
page = targetPdfWriter.GetImportedPage(sourcePdfReader, i, true);
targetPdfWriter.AddPage(page);
}
else
{
page = blankPdfWriter.GetImportedPage(sourcePdfReader, i, true);
blankPdfWriter.AddPage(page);
blankPageCount++;
}
}
}
catch (Exception ex)
{
Console.WriteLine("Exception at LOC1: " + ex.Message);
}
The error occurs in the call to targetPdfWriter.AddPage(page); near the end of the code sample.
Thank you very much for your help.

I am working on mvc 4 web application. I want to implement a functionality wherein the scenario is as follows-
There will be gmail id as input for ex: abc#gmail.com. When user will enter this, application should fetch all the calendar events of that respective email id and display them.
I have gone through this-
http://msdn.microsoft.com/en-us/library/live/hh826523.aspx#cal_rest
https://developers.google.com/google-apps/calendar/v2/developers_guide_protocol
I am new to this and i have searched a lot but not got any solution. Please help! Thanks in advance!
Got the solution . Just refer this.
https://github.com/nanovazquez/google-calendar-sample
Please check the steps below.
Add Google Data API SDK.
Try this code.. I wrote this code for one project but I removed some codes that are not related to Google Calender. If you don't want to use SDK, you can simply do http-get or http-post to your calender link based on spec.
CalendarService service = new CalendarService("A.Name");
const string GOOGLE_CALENDAR_FEED = "https://www.google.com/calendar/feeds/";
const string GOOGLE_CALENDAR_DEFAULT_ALL_CALENDAR_FULL = "default/allcalendars/full";
const string GOOGLE_CALENDAR_ALL_PRIVATE_FULL = "private/full";
private void SetUserCredentials() {
var userName = ConfigurationManager.AppSettings["GoogleUserName"];
var passWord = Security.DecryptString(ConfigurationManager.AppSettings["GooglePasswrod"]).ToInsecureString();
if (userName != null && userName.Length > 0) {
service.setUserCredentials(userName, passWord);
}
}
private CalendarFeed GetCalendarsFeed() {
CalendarQuery calendarQuery = new CalendarQuery();
calendarQuery.Uri = new Uri(GOOGLE_CALENDAR_FEED + GOOGLE_CALENDAR_DEFAULT_ALL_CALENDAR_FULL);
CalendarFeed resultFeed = (CalendarFeed)service.Query(calendarQuery);
return resultFeed;
}
private TherapistTimeSlots GetTimeSlots(CalendarEntry entry2) {
string feedstring = entry2.Id.AbsoluteUri.Substring(63);
var postUristring = string.Format("{0}{1}/{2}", GOOGLE_CALENDAR_FEED, feedstring, GOOGLE_CALENDAR_ALL_PRIVATE_FULL);
EventFeed eventFeed = GetEventFeed(postUristring);
slot.Events = new List<Event>();
if (eventFeed != null) {
var orderEventList = (from entity in eventFeed.Entries
from timeslot in ((EventEntry)entity).Times
orderby timeslot.StartTime
select entity).ToList();
}
return slot;
}
private EventFeed GetEventFeed(string postUristring) {
var eventQuery = new EventQuery();
eventQuery.Uri = new Uri(postUristring);
var h = Convert.ToInt32(DateTime.Now.ToString("HH", System.Globalization.DateTimeFormatInfo.InvariantInfo));
eventQuery.StartTime = new DateTime(DateTime.Now.Year, DateTime.Now.Month, DateTime.Now.Day, h, 0, 0);
eventQuery.EndTime = new DateTime(DateTime.Now.Year, DateTime.Now.Month, DateTime.Now.Day, h + 2, 0, 0);
try {
EventFeed eventFeed = service.Query(eventQuery) as EventFeed;
return eventFeed;
}
catch (Exception ex) {
/*
* http://groups.google.com/group/google-calendar-help-dataapi/browse_thread/thread/1c1309d9e6bd9be7
*
* Unfortunately, the calendar API will always issue a redirect to give you a
gsessionid that will optimize your subsequent requests on our servers.
Using the GData client library should be transparent for you as it is taking
care of handling those redirect; but there might some times where this error
occurs as you may have noticed.
The best way to work around this is to catche the Exception and re-send the
request as there is nothing else you can do on your part.

I m trying to attach an swf file to a pdf document. Below is my code (excerpted from the pdfbox-examples). while i can see that the file is attached based on the size of the file - with & without the attachment, I can't see / locate it in the pdf document. I do see textual content correctly displayed. Can someone tell me what I m doing wrong & help me fix the issue?
doc = new PDDocument();
PDPage page = new PDPage();
doc.addPage( page );
PDFont font = PDType1Font.HELVETICA_BOLD;
String inputFileName = "sample.swf";
InputStream fileInputStream = new FileInputStream(new File(inputFileName));
PDEmbeddedFile ef = new PDEmbeddedFile(doc, fileInputStream );
PDPageContentStream contentStream = new PDPageContentStream(doc, page,true,true);
//embedded files are stored in a named tree
PDEmbeddedFilesNameTreeNode efTree = new PDEmbeddedFilesNameTreeNode();
//first create the file specification, which holds the embedded file
PDComplexFileSpecification fs = new PDComplexFileSpecification();
fs.setEmbeddedFile(ef);
//now lets some of the optional parameters
ef.setSubtype( "swf" );
ef.setCreationDate( new GregorianCalendar() );
//now add the entry to the embedded file tree and set in the document.
Map<String, COSObjectable> efMap = new HashMap<String, COSObjectable>();
efMap.put("My first attachment", fs );
efTree.setNames( efMap );
//attachments are stored as part of the "names" dictionary in the document catalog
PDDocumentNameDictionary names = new PDDocumentNameDictionary( doc.getDocumentCatalog() );
names.setEmbeddedFiles( efTree );
doc.getDocumentCatalog().setNames( names );
After struggling with the same thing, I've discovered this is a known issue. Attachments haven't worked for a while I guess.
Here's a link to the issue on the apache forum.
There is a hack suggested here that you can use.
I tried it and it worked!
the other work around i found is after you call setNames on your PDEmbeddedFilesNameTreeNode remove the limits: ((COSDictionary
)efTree.getCOSObject()).removeItem(COSName.LIMITS); ugly hack, but it
works, without having to recompile pdfbox
Attachment works fine with new version of PDFBox 2.0,
public static boolean addAtachement(final String fileName, final String... attachements) {
if (Objects.isNull(fileName)) {
throw new NullPointerException("fileName shouldn't be null");
}
if (Objects.isNull(attachements)) {
throw new NullPointerException("attachements shouldn't be null");
}
Map<String, PDComplexFileSpecification> efMap = new HashMap<String, PDComplexFileSpecification>();
/*
* Load PDF Document.
*/
try (PDDocument doc = PDDocument.load(new File(fileName))) {
/*
* Attachments are stored as part of the "names" dictionary in the
* document catalog
*/
PDDocumentNameDictionary names = new PDDocumentNameDictionary(doc.getDocumentCatalog());
/*
* First we need to get all the existed attachments, after that we
* can add new attachments
*/
PDEmbeddedFilesNameTreeNode efTree = names.getEmbeddedFiles();
if (Objects.isNull(efTree)) {
efTree = new PDEmbeddedFilesNameTreeNode();
}
Map<String, PDComplexFileSpecification> existedNames = efTree.getNames();
if (existedNames == null || existedNames.isEmpty()) {
existedNames = new HashMap<String, PDComplexFileSpecification>();
}
for (String attachement : attachements) {
/*
* Create the file specification, which holds the embedded file
*/
PDComplexFileSpecification fs = new PDComplexFileSpecification();
fs.setFile(attachement);
try (InputStream is = new FileInputStream(attachement)) {
/*
* This represents an embedded file in a file specification
*/
PDEmbeddedFile ef = new PDEmbeddedFile(doc, is);
/* Set some relevant properties of embedded file */
ef.setCreationDate(new GregorianCalendar());
fs.setEmbeddedFile(ef);
/*
* now add the entry to the embedded file tree and set in
* the document.
*/
efMap.put(attachement, fs);
}
}
efTree.setNames(efMap);
names.setEmbeddedFiles(efTree);
doc.getDocumentCatalog().setNames(names);
doc.save(fileName);
return true;
} catch (IOException e) {
System.out.println(e.getMessage());
return false;
}
}
To 'locate' or see an attached file in the PDF, you can't flip through its pages to find any trace of it there (like, an annotation).
In Acrobat Reader 9.x for example, you have to click on the "View Attachments" icon (looking like a paper-clip) on the left sidebar.
