I'm using Aspose.words in .net API and getting in an issue to add a separate table in word footer using this tool. Can anyone expedite me to do this?
You can Insert a Table in Word footer with three cells using below piece of code:
var doc = new Document();
var builder = new DocumentBuilder(doc)
{
PageSetup =
{
Orientation = Orientation.Portrait,
PaperSize = PaperSize.Letter
},
};
builder.MoveToHeaderFooter(Word.HeaderFooterType.FooterPrimary);
builder.StartTable();
builder.InsertCell();
builder.CurrentParagraph.ParagraphFormat.Alignment = Word.ParagraphAlignment.Center;
builder.Write("Cell 1");
builder.InsertCell();
builder.CurrentParagraph.ParagraphFormat.Alignment = Word.ParagraphAlignment.Center;
builder.Write("Cell 2");
builder.InsertCell();
builder.CurrentParagraph.ParagraphFormat.Alignment = Word.ParagraphAlignment.Center;
builder.Write("Cell 3");
builder.EndTable();
builder.MoveToDocumentEnd();

Looking for word api which can perform mail merge type of functionality with richtext. Basically, text will be richtext/formatted text with fonts styles and WILL have
a) images
b) bullets
c) tables
Overall purpose: Create a word template with bookmarks. Get get data from DB(for those fields) and insert. Data will be html text/richtext. Autogenerate word document. python or .net api will be preferred.
Can Aspose.words work with richtext as described above? Any other recommendations for excellent word APIs?
Yes, you can achieve this using Aspose.Words. You can use IFieldMergingCallback to insert formatted text upon mail merge. For example, see the following link
https://apireference.aspose.com/words/net/aspose.words.mailmerging/ifieldmergingcallback
In case of reach text (if you mean RTF or MarkDown formats) you first need to read this content into a separate instance of Document and then use DocumentBuilder.InsertDocument method
https://apireference.aspose.com/words/net/aspose.words/documentbuilder/methods/insertdocument
The following code example shows how to use InsertHtml method in IFieldMergingCallback
[Test]
public void Test001()
{
Document doc = new Document(#"C:\Temp\in.docx");
doc.MailMerge.FieldMergingCallback = new HandleMergeFieldInsertHtml();
const string html = #"<h1>Hello world!</h1>";
doc.MailMerge.Execute(new string[] { "myField" }, new object[] { html });
doc.Save(#"C:\Temp\out.docx");
}
private class HandleMergeFieldInsertHtml : IFieldMergingCallback
{
void IFieldMergingCallback.FieldMerging(FieldMergingArgs args)
{
FieldMergeField field = args.Field;
// Insert the text for this merge field as HTML data, using DocumentBuilder
DocumentBuilder builder = new DocumentBuilder(args.Document);
builder.MoveToMergeField(args.DocumentFieldName);
builder.Write(field.TextBefore ?? "");
builder.InsertHtml((string)args.FieldValue);
// The HTML text itself should not be inserted
// We have already inserted it as an HTML
args.Text = "";
}
void IFieldMergingCallback.ImageFieldMerging(ImageFieldMergingArgs args)
{
// Do nothing
}
}
If you would like manually format the text, then you can use DocumentBuilder appropriate properties.
[Test]
public void Test001()
{
Document doc = new Document(#"C:\Temp\in.docx");
doc.MailMerge.FieldMergingCallback = new HandleMergeFieldInsertText();
const string text = #"Hello world!";
doc.MailMerge.Execute(new string[] { "myField" }, new object[] { text });
doc.Save(#"C:\Temp\out.docx");
}
private class HandleMergeFieldInsertText : IFieldMergingCallback
{
void IFieldMergingCallback.FieldMerging(FieldMergingArgs args)
{
FieldMergeField field = args.Field;
DocumentBuilder builder = new DocumentBuilder(args.Document);
builder.MoveToMergeField(args.DocumentFieldName);
// Apply style or other formatting.
builder.ParagraphFormat.StyleIdentifier = StyleIdentifier.Heading1;
builder.Write(field.TextBefore ?? "");
builder.Write((string)args.FieldValue);
// The text itself should not be inserted
// We have already inserted it using DocumentBuilder.
args.Text = "";
}
void IFieldMergingCallback.ImageFieldMerging(ImageFieldMergingArgs args)
{
// Do nothing
}
}
Hope this helps.

The aspose.barcode reader is unable to read the barcode of type DecodeType.Code128
Workflow Steps
1>Using Aspose.Barcode we have created a barcode using DecodeType.Code128 and put on PDF page ( our clients use this page as separator sheet)
2>Our client then insert this barcode page between several physical documents and scanned them all, which creates big single PDF
3>Our splitting process then, loop through all pages and check if any page is barcode page, and splits the big PDF into individual small PDF
Issue is some times the scanned quality of the barcode is not that great, and in such case ASPOSE.Barcode unable to read the barcode.
I have attached couple of barcode PDF with low scanned quality, and aspose is not able to read these barcodes. I have tried different combinations of RecognitionMode and ManualHints options without any luck
Below is my code to identity barcode page
using (var fs = new FileStream(file, FileMode.Open))
{
var pdfDocument = new Document(fs);
foreach (Page page in pdfDocument.Pages)
{
var isSeparator = splitter.IsSeparator(page);
Assert.IsTrue(isSeparator);
}
}
public bool IsSeparator(Page page)
{
if (page.Resources.Images != null && page.Resources.Images.Count >= 1)
{
var img = page.Resources.Images[1];
using (MemoryStream barcodeImage = new MemoryStream())
{
img.Save(barcodeImage, ImageFormat.Jpeg);
barcodeImage.Seek(0L, SeekOrigin.Begin);
using (BarCodeReader barcodeReader = new BarCodeReader(barcodeImage, _barcodeDecodeType))
{
barcodeReader.RecognitionMode = RecognitionMode.MaxQuality;
while (barcodeReader.Read())
{
var barcodeText = barcodeReader.GetCodeText();
if (barcodeText.ToLower() == "eof")
{
return true;
}
}
}
}
}
return false;
}
Unable to reproduce the issue at my end. I used the following sample code snippet to recognize the barcode along with latest version of the API. It is always recommended to use the latest version of the API as it contains new features and improvements.
CODE:
Aspose.Pdf.License licensePdf = new Aspose.Pdf.License();
licensePdf.SetLicense(#"Aspose.Total.lic");
// bind the pdf document
Aspose.Pdf.Facades.PdfExtractor pdfExtractor = new Aspose.Pdf.Facades.PdfExtractor();
pdfExtractor.BindPdf(#"173483_2.pdf");
// extract the images
pdfExtractor.ExtractImage();
// save images to stream in a loop
while (pdfExtractor.HasNextImage())
{
// save image to stream
System.IO.MemoryStream imageStream = new System.IO.MemoryStream();
pdfExtractor.GetNextImage(imageStream);
imageStream.Position = 0;
Aspose.BarCode.BarCodeRecognition.BarCodeReader barcodeReader =
new Aspose.BarCode.BarCodeRecognition.BarCodeReader(imageStream);
while (barcodeReader.Read())
{
Console.WriteLine("Codetext found: " + barcodeReader.GetCodeText() + ", Symbology: " + barcodeReader.GetCodeType().ToString());
}
// close the reader
barcodeReader.Close();
}
Further to update you that the same query has been post on Aspose.BarCode support forum. You may please visit the link for details.
I work as developer evangelist at Aspose.
I am new to Solr and SolrJ. I am trying to use for a desktop application and I have files(text files) to index and search. I wanted to use highlight feature and display the fragments with highlight,but I don't get them to display in yellow background as you highlight a text, please let me know how to display the text in yellow background.
here is my code snippet:
public void TestHighLight(SolrQuery query) throws
SolrServerException, IOException {
query.setQuery("*");
query.set("hl", "true");
query.set("hl.snippets", "5");
query.set("q", "text:Pune");
query.set("hl.fl", "*");
QueryResponse queryResponse = client.query(query);
SolrDocumentList docs = queryResponse.getResults();
Iterator iter = docs.iterator();
for (int i = 0; i < docs.size(); i++) {
iter = docs.get(i).getFieldNames().iterator();
String fldVal = (String) docs.get(i).getFieldValue("id");
String docID = (String) docs.get(i).get("id");
while (iter.hasNext()) {
String highlighText = getHighlightedText(queryResponse,
"text", docID);
System.out.println(" tHighlightedText is " + highlighText );
}
}
}
The output looks like this:how do I color it ?
[ for Java Developer at Pune
Thanks a lot !
Set the pre and post parameters of the highlighter. Specifies the “tag” to use before a highlighted term. This can be any string, but is most often an HTML or XML tag.
e.g:
solrQueryHandler.setHighlightSimplePre("<font color="yellow">");
solrQueryHandler.setHighlightSimplePost("/font");
But note that this will work only for the Original Highlighter
To be able to use different templates in a TYPO3 CMS 7.6.18 setup. I include a pageTSConfig.ts file with a backend layout looking like this. (see also this pastebin: https://pastebin.com/BcYKrYKh and this how it looks like in the TYPO3 object browser: https://pastebin.com/LVXqNUZC
### Backend Layouts #####
mod.web_layout.BackendLayouts{
1 {
title = Standaard Layout
config {
backend_layout {
colCount = 2
rowCount = 1
rows {
1 {
columns {
1 {
name = linker_inhoud
colPos = 1
}
2 {
name = midden_inhoud
colPos = 0
}
}
}
}
}
}
}
}
Since the BE-Layout is done with a file, in my TSconfig.ts I have added pagets__0 to it like the manual mentioned. Still this is not working. What Am I missing here? This is a part of the TSconfig I have in place here is the complete config:
page.10.file.stdWrap.cObject = CASE
page.10.file.stdWrap.cObject {
key.data = levelfield:-1, backend_layout_next_level, pagelayout, slide
key.override.field = pagelayout
default = TEXT
default.value = fileadmin/templates/index.html
pagets__0 = TEXT
pagets__0.value = fileadmin/templates/index.html
pagets__1 = TEXT
pagets__1.value = fileadmin/templates/layouts/small_header_page.html
pagets__2 = TEXT
pagets__2.value = fileadmin/templates/layouts/alternatieve_pagina.html
}
All to be included with:
There is a difference between "backend_layout", which is a the name of a real database field that can be fetched by "levelfield" and "pagelayout", which is a kind of virtual field to get rid of the "levelfield" approach.
https://docs.typo3.org/typo3cms/TyposcriptReference/DataTypes/Gettext/Index.html#pagelayout
key.data = pagelayout
should do the whole job for you and only in this case you can use stuff like
pagets__x
to access the actual layout.
So your code should either be:
page.10 = FLUIDTEMPLATE
page.10.file.cObject = CASE
page.10.file.cObject {
key.data = pagelayout
default = TEXT
default.value = fileadmin/templates/index.html
pagets__0 = TEXT
pagets__0.value = fileadmin/templates/index.html
pagets__1 = TEXT
pagets__1.value = fileadmin/templates/layouts/small_header_page.html
pagets__2 = TEXT
pagets__2.value = fileadmin/templates/layouts/alternatieve_pagina.html
}
or it should be
page.10 = FLUIDTEMPLATE
page.10.file.cObject = CASE
page.10.file.cObject {
key.data = levelfield:-1, backend_layout_next_level, slide
key.override.field = backend_layout
default = TEXT
default.value = fileadmin/templates/index.html
1 = TEXT
1.value = fileadmin/templates/layouts/small_header_page.html
2 = TEXT
2.value = fileadmin/templates/layouts/alternatieve_pagina.html
}
But not a mix of both approaches.
Before I tell you what might be wrong with your code, let me explain you a few things.
You have placed your templates in the fileadmin directory. This is not the place where to put these files any longer, because the fileadmin is a public place for resources like images, videos or documents. It might be available for every backend user in the filelist and the editor should not be able to edit the template in any case. The suggested way to handle your templates is to put them into an own extension that can be installed via the extension manager.
In your pastebin snippets, there is a line with userFunc = tx_templavoila_pi1->main_page, you may mixing up stuff in your installation and don't want to use FLUIDTEMPLATE alongside templavoila, because it could be confusing what rendering method is used for what stuff on your page. Better stick to templavoila or Fluid for the entirety of the TYPO3 installation.
Now, you have these lines in your TypoScript:
key.data = levelfield:-1, backend_layout_next_level, pagelayout, slide
key.override.field = pagelayout
There is no field pagelayout in the pages records. The field you rather want to address is backend_layout.
I'm using SharePoint web services in C#. I have my code working to check files and check them out using the Lists web service. I need to test to see if a file exists; I can find lots of examples for doing this using the object model API, but I can't seem to find a straightforward way of doing this using web services.
Try the Lists.GetListItems with a suitable CAML query.
A CAML query like
<Query><Where><Eq><FieldRef Name="FileLeafRef" /><Value Type="Text">Filename.rtf</Value></Eq></Where></Query>
should work; the field 'FileLeafRef' is where the filename is stored.
This code may do, it's a little rough, but demonstrates how to get a list of files based on the title.
public static bool PageExists(string listName, string webPath, string pageTitle)
{
string pageId = "";
IntranetLists.Lists lists = new IntranetLists.Lists();
lists.UseDefaultCredentials = true;
lists.Url = webPath + "/_vti_bin/lists.asmx";
XmlDocument doc = new XmlDocument();
doc.LoadXml("<Document><Query><Where><Contains><FieldRef Name=\"Title\" /><Value Type=\"Text\">" + pageTitle + "</Value></Contains></Where></Query><ViewFields /><QueryOptions /></Document>");
XmlNode listQuery = doc.SelectSingleNode("//Query");
XmlNode listViewFields = doc.SelectSingleNode("//ViewFields");
XmlNode listQueryOptions = doc.SelectSingleNode("//QueryOptions");
Guid g = GetWebID(webPath);
XmlNode items = lists.GetListItems(listName, string.Empty, listQuery, listViewFields, string.Empty, listQueryOptions, g.ToString());
}
return items.Count > 0;
}
public static XmlNodeList XpathQuery(XmlNode xmlToQuery, string xPathQuery)
{
XmlDocument doc = new XmlDocument();
doc.LoadXml(xmlToQuery.OuterXml);
XmlNamespaceManager mg = new XmlNamespaceManager(doc.NameTable);
mg.AddNamespace("sp", "http://schemas.microsoft.com/sharepoint/soap/");
mg.AddNamespace("z", "#RowsetSchema");
mg.AddNamespace("rs", "urn:schemas-microsoft-com:rowset");
mg.AddNamespace("y", "http://schemas.microsoft.com/sharepoint/soap/ois");
mg.AddNamespace("w", "http://schemas.microsoft.com/WebPart/v2");
mg.AddNamespace("d", "http://schemas.microsoft.com/sharepoint/soap/directory");
return doc.SelectNodes(xPathQuery, mg);
}
I also had similiar problems with this.
I have tried the following FieldRefs without success: "Name", "FileLeafRef" and "LinkFilenameNoMenu".
The post located at http://www.johanolivier.blogspot.com details what I had to do to get it working.
