I'm trying to locate DICOM filepaths by parsing a DICOMDIR.
But can't seem to figure out how to locate them. I parse through the DICOMDIR as follows:
DicomDirectory dir = new DicomDirectory("AE_TITLE");
dir.Load(dirPath);
foreach(DirectoryRecordSequenceItem elem in dir.RootDirectoryRecordCollection){//study
foreach(DirectoryRecordSequenceItem innerElem in elem.LowerLevelDirectoryRecordCollection){//sequence
foreach(DirectoryRecordSequenceItem inner2Elem in innerElem.LowerLevelDirectoryRecordCollection){//series
foreach (DirectoryRecordSequenceItem inner3Elem in lastElem.LowerLevelDirectoryRecordCollection) // img
{
}
}
}
}
this loops through the each study/sequence/series/image but non of these seem to contain a filepath to a .dcm file.
P.S. I use the ClearCanvas library to create the DicomDirectory object
It appears that if you go to the lowest level (image level) the dicomfile has an attribute ReferencedFileId which holds the relative path so all that was needed is:
Console.inner3Elem.GetAttribute(DicomTags.ReferencedFileId).ToString();
This returns the path to the dicom file relative to where the DICOMDIR is located

I am trying to obtain the name of a file (JSON format but saved without an extension) within the last directory of a given path. Each file is saved with its own unique subpath inside the app's data container.
I also need to get the full path of the file, including the filename.
From what I've read, I believe it is better to use URLs to do this rather than using string paths.
I have tried the following code:
do {
let enumerator = FileManager.default.enumerator(at: filePath, includingPropertiesForKeys: nil)
while let element = enumerator?.nextObject() as? URL {
var nexObject = element.lastPathComponent
print(nextObject)
}
} catch let error {
print(error.localizedDescription)
}
This does seem to iterate through each level of the path until the end. Great, but what is the best way to get the full path, including the filename, other than concatenation of each object from the above?
All advice gratiously received. Thanks!
As element is an URL, if you're interested in the full path name rather than the last component, just go for:
var nextObject = element.absoluteURL // instead of .lastPathComponent
or just
var nextObject = element.path // or even relativePath
Thank you, #Christophe (+1)
I've also since spotted that the documentation for enumerator(at:includingPropertiesForKeys:options:errorHandler:) provides a nice example, which can be modifed for my purposes by using additional resource keys (e.g. name, path, etc.).
I've been searching for a couple of days on how to get the album art for a song (or a frame capture of a video) from a file path. All I could find is things related to Mediastore like this answer where it requires getting the album ID of the file.
Cursor cursor = getContentResolver().query(MediaStore.Audio.Albums.EXTERNAL_CONTENT_URI,
new String[] {MediaStore.Audio.Albums._ID, MediaStore.Audio.Albums.ALBUM_ART},
MediaStore.Audio.Albums._ID+ "=?",
new String[] {String.valueOf(albumId)},
null);
if (cursor.moveToFirst()) {
String path = cursor.getString(cursor.getColumnIndex(MediaStore.Audio.Albums.ALBUM_ART));
// do whatever you need to do
}
But I can't find a guid on how it works, how can pass the file to Mediastore or how can I get the album ID of the media or anything... Currently I get the media information using MediaMetadataRetriever but I can't find a way to get the album art or a video thumbnail of a media file using it...
** Update :-
If Mediastore must be used to get the media files in the first place before using it to get their data, I can implement it instead of what I'm currently doing (Currently I iterate the device files to get the supported files) and it can be a better option as Mediastore supports getting data from external storages as well.
Any help is appreciated.
If using MediaMetadataRetriever , you can have a try with follow sample code :
private void loadingCover(string mediaUri)
{
MediaMetadataRetriever mediaMetadataRetriever = new MediaMetadataRetriever();
mediaMetadataRetriever.SetDataSource(mediaUri);
byte[] picture = mediaMetadataRetriever.GetEmbeddedPicture();
Android.Graphics.Bitmap bitmap = BitmapFactory.DecodeByteArray(picture, 0, picture.Length);
musicCover.SetImageBitmap(bitmap);
}
In addition , not forgatting to add permission :
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
Invoke it as follow :
File file = new File("/storage/sdcard/Movies/music1.mp4");
if (file.Exists())
{
loadingCover(file.AbsolutePath);
}
I googled so far and tried to find out the solution but not yet.
I know require() works only with static path, so I want alternative ways to solve my problem. I found this answer here but it doesnt make sense for thousands of resources.
Please advise me the best approach to handle such case.
Background
I have thousand of json files that containing app data, and declared all the file path dynamically like below:
export var SRC_PATH = {
bible_version_inv: {
"kjv-ot": "data/bibles/Bible_KJV_OT_%s.txt",
"kjv-nt": "data/bibles/Bible_KJV_NT_%s.txt",
"lct-ot": "data/bibles/Bible_LCT_OT_%s.txt",
"lct-nt": "data/bibles/Bible_LCT_NT_%s.txt",
"leb": "data/bibles/leb_%s.txt",
"net": "data/bibles/net_%s.txt",
"bhs": "data/bibles/bhs_%s.txt",
"n1904": "data/bibles/na_%s.txt",
.....
"esv": "data/bibles/esv_%s.txt",
.....
},
....
As you can see, file path contains '%s' and that should be replace with right string depends on what the user selected.
For example if user select the bible (abbreviation: "kjv-ot") and the chapter 1 then the file named "data/bibles/Bible_KJV_OT_01.txt" should be imported.
I'm not good enough in react-native, just wondering if there is other alternative way to handle those thousands of resource files and require only one at a time by dynamically following the user's selection.
Any suggestions please.
Instead of exporting a flat file, you could export a function that took a parameter which would help build out the paths like this:
// fileInclude.js
export const generateSourcePath = (sub) => {
return {
bible_version_inv: {
"kjv-ot": `data/bibles/Bible_KJV_OT_${sub}.txt`
}
}
}
//usingFile.js
const generation = require('./fileInclude.js');
const myFile = generation.generateSourcePath('mySub');
const requiredFile = require(myFile);
then you would import (or require) this item into your project, execute generateSourcePath('mysub') to get all your paths.
I have kept a word document (.docx) in one of the project folders which I want to use as a template.
This template contains custom header and footer lines for user. I want to facilitate user to download his own data in word format. For this, I want to write a function which will accept user data and referring the template it will create a new word file replacing the place-holders in the template and then return the new file for download (without saving it to server). That means the template needs to be intact as template.
Following is what I am trying. I was able to replace the placeholder. However, I am not aware of how to give the created content as downloadable file to user. I do not want to save the new content again in the server as another word file.
public void GenerateWord(string userData)
{
string templateDoc = HttpContext.Current.Server.MapPath("~/App_Data/Template.docx");
// Open the new Package
Package pkg = Package.Open(templateDoc, FileMode.Open, FileAccess.ReadWrite);
// Specify the URI of the part to be read
Uri uri = new Uri("/word/document.xml", UriKind.Relative);
PackagePart part = pkg.GetPart(uri);
XmlDocument xmlMainXMLDoc = new XmlDocument();
xmlMainXMLDoc.Load(part.GetStream(FileMode.Open, FileAccess.Read));
xmlMainXMLDoc.InnerXml = ReplacePlaceHoldersInTemplate(userData, xmlMainXMLDoc.InnerXml);
// Open the stream to write document
StreamWriter partWrt = new StreamWriter(part.GetStream(FileMode.Open, FileAccess.Write));
xmlMainXMLDoc.Save(partWrt);
partWrt.Flush();
partWrt.Close();
pkg.Close();
}
private string ReplacePlaceHoldersInTemplate(string toReplace, string templateBody)
{
templateBody = templateBody.Replace("#myPlaceHolder#", toReplace);
return templateBody;
}
I believe that the below line is saving the contents in the template file itself, which I don't want.
xmlMainXMLDoc.Save(partWrt);
How should I modify this code which can return the new content as downloadable word file to user?
I found the solution Here!
This code allows me to read the template file and modify it as I want and then to send response as downloadable attachment.
I have path Manipulation problem. The following code is placed in Page_load method of ASPx page.
String rName = Request.QueryString["reportName"];
string path = "C:\\hari" + rName;
if (File.Exists(path))
{
File.Delete(path);
}
But Fortify scan report for the above sample code shows ‘Path Manipulation’ issue as high
Need help to modify above code so that it can pass fortify scan
Jackson is right, this is a direct File Path Manipulation vulnerability that can be fixed through indirect selection.
From your known directory, list all the files. Use the value coming from your own directory list, not the user-supplied value.
String rName = Request.QueryString["reportName"];
String knownPath = "C:\\hari";
DirectoryInfo di = new DirectoryInfo(knownPath);
FileInfo[] files = di.GetFiles(rName);
if (files.length > 0)
{
files[0].Delete();
}
I think the problem is that someone could spoof a request with reportName = "..\\Windows\\Something important" which is clearly a security flaw. You need to change your code so that it doesn't read a partial filename from the request query string.
