I need to call some file uploader JavaScript from code behind. The JavaScript is basically customizing the style of the file uploader control. However, the JavaScript function can't find the element. I get this from the inspector:
*o = {element: null,
action: "/Web/UploadHandler.axd?UploadID=55f3930c-6aa9-4201…ccfdfae6c6&ObjectID=145649&RelationshipTypeID=223",
sizeLimit: 209715
when it should look like this:
o = {element: div#uploadContent, action: "/Web/UploadHandler.axd?UploadID=c1829b40-7869-4f19…411e7a542c&ObjectID=151808&RelationshipTypeID=223", sizeLimit: 20971520, acceptTypes: "image/*", onSubmit: ƒ, …}
qq.extend
This is the code:
div = new HtmlGenericControl("div") { ID = ("dlWrapper") };
Literal litScript = new Literal();
litScript.Mode = LiteralMode.PassThrough;
div.Controls.Add(litScript);
var imageUploader = (ImageUpload)CreateImageUploader(ActiveObject, p, litScript);
div.Controls.Add(imageUploader);
controls.Add(div);
private static Control CreateImageUploader(ObjectInstance objectInstance, PropertyType propertyType, Literal litScript)
{
ImageUpload imageUpload = new ImageUpload (objectInstance, litScript) { ID = ControlFactory.GetControlId(ControlFactory.IMAGE_PREFIX, ControlFactory.PROPERTY_TYPE_PREFIX, objectInstance.Id, propertyType.Id), Width = Unit.Pixel(80), Height = Unit.Pixel(30) };
PropertyInstanceValue piv = objectInstance.GetPropertyInstanceValue(propertyType.Id);
return imageUpload;
}
public class ImageUpload : FileUpload
{
public ObjectInstance ActiveObject {get; set; }
public Literal litScript { get; set; }
private string uploadID;
private string accept = "image/*";
public string UploadID
{
get
{
if (string.IsNullOrEmpty(uploadID))
{
uploadID = GetUploadID();
}
return uploadID;
}
set { uploadID = value; }
}
public ImageUpload(ObjectInstance activeObject, Literal literal)
{
ActiveObject = activeObject;
litScript = literal;
}
public string GetUploadID()
{
string uploadID;
if (HttpContext.Current.Session[EDM.Common.Definitions.SessionKey.UPLOAD_ID] != null)
{
uploadID = (string)HttpContext.Current.Session[EDM.Common.Definitions.SessionKey.UPLOAD_ID];
HttpContext.Current.Cache.Remove("cacheFlashSessionID_" + uploadID);
HttpContext.Current.Cache.Remove("cacheFlashAuth_" + uploadID);
}
uploadID = Guid.NewGuid().ToString();
HttpContext.Current.Session[EDM.Common.Definitions.SessionKey.UPLOAD_ID] = uploadID;
HttpContext.Current.Cache.Insert("cacheFlashSessionID_" + uploadID, HttpContext.Current.Session.SessionID, null, DateTime.Now.AddMinutes(20), Cache.NoSlidingExpiration, CacheItemPriority.NotRemovable, null);
if (HttpContext.Current.Request.Cookies[FormsAuthentication.FormsCookieName] != null)
{
// ReSharper disable PossibleNullReferenceException
HttpContext.Current.Cache.Insert("cacheFlashAuth_" + uploadID, HttpContext.Current.Request.Cookies[FormsAuthentication.FormsCookieName].Value, null, DateTime.Now.AddMinutes(20), Cache.NoSlidingExpiration, CacheItemPriority.NotRemovable, null);
// ReSharper restore PossibleNullReferenceException
}
return uploadID;
}
protected override void OnLoad(EventArgs e)
{
Literal litScript = new Literal();
ScriptManager scriptManager = ScriptManager.GetCurrent(Page);
StringBuilder sb = new StringBuilder();
sb.Append("<div id=\"uploadContent\"></div>");
litScript.Text = sb.ToString();
sb.Remove(0, sb.Length);
sb.Append("<script type=\"text/javascript\">");
int maxBytes = ProcessUnity.Common.Utility.GetMaxRequestLength() * 1024;
sb.Append("var uploader = new qq.FileUploader({ element: document.getElementById('uploadContent'), action: '" + Context.Request.ApplicationPath + "/UploadHandler.axd?UploadID=" + UploadID + "&ObjectID=" + ActiveObject.Id + "&RelationshipTypeID=" + EDM.Common.Definitions.RelationshipTypeId.IMAGE_FILE + "', sizeLimit: " + maxBytes + ", acceptTypes:'" + accept + "', onSubmit: uploadStart, onComplete: uploadComplete, onError: uploadError, multiple: false });");
sb.Append("</script>");
if (scriptManager != null)
{
ScriptManager.RegisterClientScriptBlock(this, typeof(ImageUpload), Guid.NewGuid().ToString(), sb.ToString(), false);
}
else
{
Page.ClientScript.RegisterClientScriptBlock(typeof(Page), Guid.NewGuid().ToString(), sb.ToString());
}
base.OnLoad(e);
}
private object GetScriptManager()
{
foreach (DictionaryEntry entry in Page.Items)
{
if (entry.Key.ToString().IndexOf("System.Web.UI.ScriptManager") >= 0)
{
return entry.Value;
}
}
return null;
}
}
It looks like you're expecting litScript here:
Literal litScript = new Literal();
litScript.Mode = LiteralMode.PassThrough;
div.Controls.Add(litScript);
To be modified by the OnLoad event:
protected override void OnLoad(EventArgs e)
{
Literal litScript = new Literal();
// ...
StringBuilder sb = new StringBuilder();
sb.Append("<div id=\"uploadContent\"></div>");
litScript.Text = sb.ToString();
// ...
base.OnLoad(e);
}
But your OnLoad is constructing its own local Literal. Just because it has the same litScript name as the outer Literal doesn't mean that the two are related. In short, nothing is writing that div to the page.

I have a program where a text file is read in and then each word in the file is outputted, followed by the # of times it is repeated throughout the file.
Use the following code.
import java.io.*;
class FileRead {
public static void main(String args[]) {
try {
// Open the file that is the first
// command line parameter
FileInputStream fstream = new FileInputStream("C:\\Users\\Desktop\\formate.txt");
// Get the object of DataInputStream
DataInputStream in = new DataInputStream(fstream);
BufferedReader br = new BufferedReader(new InputStreamReader(in));
String strLine;
//Read File Line By Line
while ((strLine = br.readLine()) != null) {
// Print the content on the console
System.out.println(strLine);
}
//Close the input stream
in.close();
} catch (Exception e) {//Catch exception if any
System.err.println("Error: " + e.getMessage());
}
}
}
Try this code:
public static void main(String[] args) throws Throwable
{
File inputFile = new File("input.txt");
File outputFile = new File("output.txt");
Scanner scanner = new Scanner(inputFile);
HashMap<String, Integer> count = new HashMap<String, Integer>();
while (scanner.hasNext())
{
String word = scanner.next();
if (count.containsKey(word))
{
count.put(word, count.get(word) + 1);
}
else
{
count.put(word, 1);
}
}
scanner.close();
BufferedWriter writer = new BufferedWriter(new FileWriter(outputFile));
for (Entry<String, Integer> entry : count.entrySet())
{
writer.write("#" + entry.getKey() + " " + entry.getValue()+"\r\n");
}
writer.close();
}
This also, it is a lot simpler if You can't use HashMap or BufferedReader:
import java.io.BufferedWriter;
import java.io.File;
import java.io.FileWriter;
import java.io.IOException;
import java.util.LinkedList;

}
scanner.close();

}

}
writer.close();
}

{

{

{

return;
}
}
words.add(new Word(word, 1));
}
}

{
private String word;
private int count;
public Word(String word, int count)
{
this.word = word;
this.count = count;
}
public String getWord()
{
return word;
}
public void setWord(String word)
{
this.word = word;
}
public int getCount()

}

I am trying to access public methods from a C# class library (dll) from javascript, specifically a Rhino package for javascript.
Here is what I'm trying to do:
namespace ReturnINT
{
public class ReturnINT
{
public static int RetornaInteiro ()
{
try
{
int number = 2;
return number;
}
catch (Exception)
{
return 1;
}
}
}
}
I created a class library from above code or to be precise a dll file. Now I want to access this dll in my javascript, but I don't want to create any wrappers, which is mentioned in some other threads.
Can someone please guide me here and let me know if I need to perform some setting while creating the dll file?

In mustache/handlerbars or any templating system in js,
are there any tools to gather all the variables that a template refers to?
for example, given input
templateHTML:
<div class="{{divclass}}">
{#item}}
<h1>{{title}}</h1>
<span>{{text}}</span>
{{/item}}
</div>
would return
{
divclass: "",
item: {
title: "",
text: ""
}
}
when used like MyTemplateTool.getTemplateData(templateHTML)
I tried googling around and checking out handlebars docs but could not find anything suitable
I believe it's just .. See the related docs on paths. Example:
{{#srcs}}
<script src="{{.}}"></script>
{{/srcs}}

Give the template file path at the command line - you need java 7 or higher to open the file, or you can just rewrite the readFile - method. You can produce a json or java 'schema' by changing the format at the top of the class. The 'schema' gets written to stdout, you can copy it from there and paste it into where you need it. Hope this helps. Ah! This doesn't support partials or set delimiters, but if you get round to writing support ping it to me as I might want it :)
