I am trying to use the ZipFiles() utility method and its producing an empty zip file. I am using Sitecore 6.5. There are no error, permissions or otherwise.
Any thoughts? Here is the code.
public void CreateZipFile(string zipfileName, List<string> files)
{
var zipfile = string.Format("{0}/{1}/{2}", TempFolder.Folder, "myfolder", zipfileName) ;
var fileArray = files.ToArray();
var x = FileUtil.ZipFiles(zipfile, fileArray);
}
EDIT:
I am passing the files like this
var files = new List<string> { FileUtil.MapPath("/temp/sample.xlf") };
The proper usage of FileUtil.ZipFiles method is:
FileUtil.ZipFiles("/test.zip", new []{"/web.config", "/otherfile.txt"})
Sitecore automatically maps paths. The zip file will be created in your web app root.
EDIT AFTER COMMENT
If you want to create a zip file outside the web root and with a flat structure inside, you can use Sitecore ZipWriter class like this:
public static string ZipFiles(string absolutePathToZipfile, string[] files)
{
using (ZipWriter zipWriter = new ZipWriter(absolutePathToZipfile))
{
foreach (string path in files)
{
using (FileStream fileStream = System.IO.File.OpenRead(path.StartsWith("/") ? FileUtil.MapPath(path) : path))
zipWriter.AddEntry(FileUtil.GetFileName(path), fileStream);
}
}
return absolutePathToZipfile;
}

I've been using the S3 connector for a couple of weeks now, and I want to change the way the connector names each file. I am using the HourlyBasedPartition, so the path to each file is already enough for me to find each file, and I want the filenames to be something generic for all the files, like just 'Data.json.gzip' (with the respective path from the partitioner).
For example, I want to go from this:
<prefix>/<topic>/<HourlyBasedPartition>/<topic>+<kafkaPartition>+<startOffset>.<format>
To this:
<prefix>/<topic>/<HourlyBasedPartition>/Data.<format>
The objective of this is to only make one call to S3 to download the files later, instead of having to look for the filename first and then download it.
Searching through the files from the folder called 'kafka-connect-s3', I found this file:
https://github.com/confluentinc/kafka-connect-storage-cloud/blob/master/kafka-connect-s3/src/main/java/io/confluent/connect/s3/TopicPartitionWriter.java which at the end has some of the following functions:
private RecordWriter getWriter(SinkRecord record, String encodedPartition)
throws ConnectException {
if (writers.containsKey(encodedPartition)) {
return writers.get(encodedPartition);
}
String commitFilename = getCommitFilename(encodedPartition);
log.debug(
"Creating new writer encodedPartition='{}' filename='{}'",
encodedPartition,
commitFilename
);
RecordWriter writer = writerProvider.getRecordWriter(connectorConfig, commitFilename);
writers.put(encodedPartition, writer);
return writer;
}
private String getCommitFilename(String encodedPartition) {
String commitFile;
if (commitFiles.containsKey(encodedPartition)) {
commitFile = commitFiles.get(encodedPartition);
} else {
long startOffset = startOffsets.get(encodedPartition);
String prefix = getDirectoryPrefix(encodedPartition);
commitFile = fileKeyToCommit(prefix, startOffset);
commitFiles.put(encodedPartition, commitFile);
}
return commitFile;
}
private String fileKey(String topicsPrefix, String keyPrefix, String name) {
String suffix = keyPrefix + dirDelim + name;
return StringUtils.isNotBlank(topicsPrefix)
? topicsPrefix + dirDelim + suffix
: suffix;
}
private String fileKeyToCommit(String dirPrefix, long startOffset) {
String name = tp.topic()
+ fileDelim
+ tp.partition()
+ fileDelim
+ String.format(zeroPadOffsetFormat, startOffset)
+ extension;
return fileKey(topicsDir, dirPrefix, name);
}
I don't know if this can be customised to what I want to do but seems to be somehow near/related to my intentions. Hope it helps.
(Submitted an issue to Github as well: https://github.com/confluentinc/kafka-connect-storage-cloud/issues/369)
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.

I have three solution configurations in my UWP solution in Visual Studio:
Development
Staging
Production
Each is a associated with a different web service and auth provider in the configuration files. In my code, how do I tell which one is which? In the past I've explicitly provided DEFINE constants, but there must be a better way by now.
The active solution configuration is stored in the .suo file beneath the .vs directory at the root solution folder. The .suo file has a compound file binary format, which means you can't just parse it with text manipulation tools.
However, using OpenMcdf -- a tool that can be used to manipulate these types of files -- you can easily get the active solution configuration.
Here's a console app I wrote that works. Feel free to adapt the code to your situation:
using OpenMcdf;
using System;
using System.IO;
using System.Linq;
using System.Text;
namespace GetActiveBuildConfigFromSuo
{
internal enum ProgramReturnCode
{
Success = 0,
NoArg = -1,
InvalidFileFormat = -2
}
internal class Program
{
private const string SolutionConfigStreamName = "SolutionConfiguration";
private const string ActiveConfigTokenName = "ActiveCfg";
internal static int Main(string[] args)
{
try
{
ValidateCommandLineArgs(args);
string activeSolutionConfig = ExtractActiveSolutionConfig(
new FileInfo(args.First()));
throw new ProgramResultException(
activeSolutionConfig, ProgramReturnCode.Success);
}
catch (ProgramResultException e)
{
Console.Write(e.Message);
return (int)e.ReturnCode;
}
}
private static void ValidateCommandLineArgs(string[] args)
{
if (args.Count() != 1) throw new ProgramResultException(
"There must be exactly one command-line argument, which " +
"is the path to an input Visual Studio Solution User " +
"Options (SUO) file. The path should be enclosed in " +
"quotes if it contains spaces.", ProgramReturnCode.NoArg);
}
private static string ExtractActiveSolutionConfig(FileInfo fromSuoFile)
{
CompoundFile compoundFile;
try { compoundFile = new CompoundFile(fromSuoFile.FullName); }
catch (CFFileFormatException)
{ throw CreateInvalidFileFormatProgramResultException(fromSuoFile); }
if (compoundFile.RootStorage.TryGetStream(
SolutionConfigStreamName, out CFStream compoundFileStream))
{
var data = compoundFileStream.GetData();
string dataAsString = Encoding.GetEncoding("UTF-16").GetString(data);
int activeConfigTokenIndex = dataAsString.LastIndexOf(ActiveConfigTokenName);
if (activeConfigTokenIndex < 0)
CreateInvalidFileFormatProgramResultException(fromSuoFile);
string afterActiveConfigToken =
dataAsString.Substring(activeConfigTokenIndex);
int lastNullCharIdx = afterActiveConfigToken.LastIndexOf('\0');
string ret = afterActiveConfigToken.Substring(lastNullCharIdx + 1);
return ret.Replace(";", "");
}
else throw CreateInvalidFileFormatProgramResultException(fromSuoFile);
}
private static ProgramResultException CreateInvalidFileFormatProgramResultException(
FileInfo invalidFile) => new ProgramResultException(
$#"The provided file ""{invalidFile.FullName}"" is not a valid " +
$#"SUO file with a ""{SolutionConfigStreamName}"" stream and an " +
$#"""{ActiveConfigTokenName}"" token.", ProgramReturnCode.InvalidFileFormat);
}
internal class ProgramResultException : Exception
{
internal ProgramResultException(string message, ProgramReturnCode returnCode)
: base(message) => ReturnCode = returnCode;

Basically, I'm trying to return a collection of strings in Java.
But...
each string must be unique because they're all the names of ".db" files in current folder, so I thought this collection should be LinkedHashSet.
The elements (filenames) must maintain the exact same order, so I can choose one of them by it's order number in the collection.
My main routine will show this collection in a GUI component (maybe a JList) for the user to choose one of them (without the .db extension).
I'm totally newbie (as you can see), so if you think there are better options than LinkedHashSet please tell me.
Also, how can I grab this collection in the main class?
What I've got so far:
public Set GetDBFilesList() {
//returns ORDERED collection of UNIQUE strings with db filenames
LinkedHashSet a = new LinkedHashSet();
FilenameFilter dbFilter = (File file, String name) -> {
return name.toLowerCase().endsWith(".db");
};
String dirPath = "";
File dir = new File(dirPath);
File[] files = dir.listFiles(dbFilter);
if (files.length > 0) {
for (File aFile : files) {
a.add(aFile.getName());
}
}
return a;
}
You want an ordered and unique collection - LinkedHashSet is a good choice.
Some comments on your methode:
Your should use Generics f.e.: LinkedHashSet<File> or LinkedHashSet<String>
The check for files.length is unnecessary, but you could check for null if the path is not a directory or an I/O error occured
You should name your variables properly: a is not a good name
Your methode can be static - maybe in a static helper class?
The Set.add methode returns true or false if the item was added or not, you should check that just in case
Putting all together:
//Your Main class
public class Main
{
public static void main(String[] args)
{
File dir = new File("");
Collection<File> dbFiles = DbFileManager.getDatabaseFiles(dir);
}
}
//Your DB File Reader Logic
public class DbFileManager
{
public static Collection<File> getDatabaseFiles(File directory)
{
Collection<File> dbFiles = new LinkedHashSet<>();
//filter code etc.
boolean success = dbFiles.addAll(directory.listFiles(filter));
//Check if everthing was added
return dbFiles;
}
}
I'm using the following code, using the SharpZipLib library, to add files to a .zip file, but each file is being stored with its full path. I need to only store the file, in the 'root' of the .zip file.
string[] files = Directory.GetFiles(folderPath);
using (ZipFile zipFile = ZipFile.Create(zipFilePath))
{
zipFile.BeginUpdate();
foreach (string file in files)
{
zipFile.Add(file);
}
zipFile.CommitUpdate();
}
I can't find anything about an option for this in the supplied documentation. As this is a very popular library, I hope someone reading this may know something.
My solution was to set the NameTransform object property of the ZipFile to a ZipNameTransform with its TrimPrefix set to the directory of the file. This causes the directory part of the entry names, which are full file paths, to be removed.
public static void ZipFolderContents(string folderPath, string zipFilePath)
{
string[] files = Directory.GetFiles(folderPath);
using (ZipFile zipFile = ZipFile.Create(zipFilePath))
{
zipFile.NameTransform = new ZipNameTransform(folderPath);
foreach (string file in files)
{
zipFile.BeginUpdate();
zipFile.Add(file);
zipFile.CommitUpdate();
}
}
}
What's cool is the the NameTransform property is of type INameTransform, allowing customisation of the name transforms.
How about using System.IO.Path.GetFileName() combined with the entryName parameter of ZipFile.Add()?
string[] files = Directory.GetFiles(folderPath);
using (ZipFile zipFile = ZipFile.Create(zipFilePath))
{
zipFile.BeginUpdate();
foreach (string file in files)
{
zipFile.Add(file, System.IO.Path.GetFileName(file));
}
zipFile.CommitUpdate();
}
The MSDN entry for Directory.GetFiles() states that The returned file names are appended to the supplied path parameter. (http://msdn.microsoft.com/en-us/library/07wt70x2.aspx), so the strings you are passing to zipFile.Add() contain the path.
According to the SharpZipLib documentation, there is an overload of the Add method,
public void Add(string fileName, string entryName)
Parameters:
fileName(String) The name of the file to add.
entryName (String) The name to use for the ZipEntry on the Zip file created.
Try this approach:
string[] files = Directory.GetFiles(folderPath);
using (ZipFile zipFile = ZipFile.Create(zipFilePath))
{
zipFile.BeginUpdate();
foreach (string file in files)
{
zipFile.Add(file, Path.GetFileName(file));
}
zipFile.CommitUpdate();
}
