How to create Remote Desktop Application in C# or port it from HTML5/JS project ?

Hi
How can create Remote Desktop Application in C# template ? I were searching on google but not found example or API for this.
If can, please suggest for me some solution, example and document.
And I have JavaScript project template Remote Desktop Application. Can i port it to c# ? Or use Webview to show it ?
I were create demo use webview to show it but it not run. Maybe i do some mistake or can't be do it.
Thanks.

I have no other options. We already provide the RDP plug-in for JavaScript. I'm not sure what else is needed for this.
Matt Small - Microsoft Escalation Engineer - Forum Moderator
If my reply answers your question, please mark this post as answered.
NOTE: If I ask for code, please provide something that I can drop directly into a project and run (including XAML), or an actual application project. I'm trying to help a lot of people, so I don't have time to figure out weird snippets with
undefined objects and unknown namespaces.
My project needs work with C# Windows Store. So I need RDP on C#, not JS. If we don't support C#, do we have a RDP spec on Windows 8.1 so that we can follow that spec to implement with native code to support RDP?

How to write a messenger with using java?

May I know how to write a messenger with using java? The messenger need included two functions which are file transfer and add users to join the conversation.
Thank you.

Ok, so you need to start from the beginning, the requirements, is it a swing (i.e. GUI) app, web app, console, etc...?
As stated by sprizor making an IM client is no easy task, you need to both implement the server side and the client side, which both communicate with each other, file transfers are also quite complex, and even maintaining a multi-user chat can be quite difficult.
If you are after a Web Based app, then you will need to look into Push technologies, like Grizzly Comet which is a nice wrapper for the NIO java stuff:
https://grizzly.dev.java.net/
Good luck...

How to run a remote application (Non Java) from a Java program

Could you please tell me how to run a remote application (Non-Java) from a Java program without using RMI. Please tell me know the procedure and classes to be used.
Cheers
Ram

what do you mean remote application.In the other pc or in your pc just apart from you application?
If the application is in your pc,the method which the upper has mentioned is
a good one!
But if the application you want to run is not in your computer,the method can't do. And you can use socket with which you can build an application listening some port in the pc which contains the application you want to run .When you want to run that application ,send the Start_Command to the listening application.Then listening application will run the application with the help of the method the upper mentioned.

Commercial Desktop applications in Java

Could someone give me some good examples of commercial desktop applications (except IDE's) written in Java?
A friend of mine needs to convince his boss that Java is a feasible language for serious desktop applications.

Have you verified that your mysql allows network connections?
In order to allow network connections you have to comment or remove line "skip-networking" in my.ini(windows) or my.cnf(unix) configuration files of your mysql instance.
Or if you have the mysql administrator installed
MySQL Administrator / Startup Variables / Disable networking (uncheck)

How to write a SQL query in Java

How to write as XML file using java 1.5

hi all,
i am trying to create an XML file using java 1.5. I took a XML creating java file which was working with java 1.4 and ported same file into java 1.5 with changes according to the SAX and DOM implmentation in java 1.5 and tried to compile. But while writing as a file it throws error "cannot find the symbol."
can any body help me out to solve this issue.......

// parent node reference
Element rootnd = (Element) xmlDoc.createElement("ALL_TABLES");
// root node
xmlDoc.appendChild(rootnd);
Element rownd = (Element) xmlDoc.createElement("ROW");
rootnd.appendChild(rownd);
Element statusnd = (Element) xmlDoc.createElement("FILE_STATUS");
rownd.appendChild(statusnd);
statusnd.appendChild(xmlDoc.createTextNode("Y")
FileOutputStream outpt = new FileOutputStream(outdir + "//forbranch.xml");
Writer outf = new OutputStreamWriter(outpt, "UTF-8");
//error is occuring here Since write method is not available in the Document class
xmlDoc.write(outf);
outf.flush();

Hi,
when I look in the JDK1.4.2 specification I don't see any write method in the Document interface.
However, your solution is the Transformer class. There you transform your DOM tree into any output you need. Your code sould look something like this:     TransformerFactory tf = TransformerFactory.newInstance();
     // set all necessary features for your transformer -> see OutputKeys
     Transformer t = tf.newTransformer();
     t.transform(new DOMSource(xmlDoc), new StreamResult(file));Then you have your XML file stored in the file system.
Hope it helps.

<b>where to get the jar and sda files to build the application??
In Developer Studio.. Windows -> Preferences -> Java -> Classpath variables. Is this the only place where we need to give the jar file path??
Are there any other configurations to do(except setting container variable to MDM4J jar file) to connect my java application to MDM repository???</b>
Regards,
Chand.

Hi Govada,
(1)You need to add the MDM4j and other JAR files at:-
right click on project -> Java Build Path -> Libraries -> Add External JARs
(2)If the project is Web Dynpro project one
then right click on project -> Web Dynpro Reference -> Library Reference -> and add sap.com/com.sap.mdm.tech.mdm4j
Are you using JAVA API 1 or 2???
Thanking you

How to write c or c++ or Java languages in abap

dear sir,
i want to capture the screen and attach with mail content while creating the support message in R/3 system .. i dont know how to capture the print screen button in ABAP .. but i know in C , C++ and Java . i am having that code .. now i want to how to embed that code in ABAP editor .. Whether it is possible or not ..
Please reply,
Regards,
kumar

Hi kumaresan,
though you can compile and execute JAVA script from ABAP , there is no compiler provided in ABAP for C / C++. You can have a look at the class - CL_JAVA_SCRIPT.
if you are trying to capture and send a particular screen shot - possibly you need to create a ActiveX control - which will capture the screen and create the image file for you. And at the same time it needs to pass back the binary streams for the image. SAP allows external call to Activex controls via OLE framework ( u ll getsamples for calling Excel, Custom Container etc ). may be u can try at that line.
Bottom line is if you r looking for C, C++ or Java compilers inside ABAP - i am afraid - its not possible..

How can I invoke JavaFX application in Java project

I want to set an actionlistener on a button.When I click the button,it will run the JavaFX application.
Any idea?Thanks in advance.

A program that launches JavaFX programs? Something like this might work:
     * Launches the given JNLP file.
     * @param jnlpFileURL The url to the JNLP file of the JavaFX application we are launching.
    public void launchFXApplication(String jnlpFileURL) throws Exception {
        //Retrieve the runtime.
        Runtime runtime = Runtime.getRuntime();
        //Create the commands we will be executing.
        String[] commands = new String[] {
            System.getProperty("java.home") + File.separator + "bin" + File.separator + "javaws",
            jnlpFileURL
        //Execute it.
        final Process process = runtime.exec(commands);
        //Need to read the input.
        final BufferedReader errorReader = new BufferedReader(
            new InputStreamReader(process.getErrorStream()));
        final BufferedReader outputReader = new BufferedReader(
            new InputStreamReader(process.getInputStream()));
        //Input MUST be read and should be done in separate threads.
        Thread errorThread = new Thread(new Runnable() {
            public void run() {
                String line;
                try {
                    while ((line = errorReader.readLine()) != null) {
                        //Examine it if you like. Optional.
                    errorReader.close();
                } catch (IOException ex) {
                    ex.printStackTrace();
        Thread outputThread = new Thread(new Runnable() {
            public void run() {
                String line;
                try {
                    while ((line = outputReader.readLine()) != null) {
                        //Doing something with the input is optional.
                    errorReader.close();
                } catch (IOException ex) {
                    ex.printStackTrace();
        //Run the separate threads.
        errorThread.start();
        outputThread.start();
        //Wait until it's done.
        process.waitFor();
    }This code will of course need to be signed if you intend to launch it as an applet or via webstart.

In other words, How to pass a Java Object from a Java stored procedure to a Java client ???
Hello,
I don't know to deal with a Vector object that has been generated from a stored procedure.
Should I create first in the JDBC client and pass it as argument to the procedure ?
Thanks in advance. Here is an extract ...
On the client side :
<<
Vector buffer = new Vector();
CallableStatement call =
con.prepareCall ("{call my_procedure_run (?, ?)}");
call.registerOutParameter(2, java.sql.Types.JAVA_OBJECT );
call.setString (1, "bla bla bla");
call.setObject (2, buffer);
call.execute ();
buffer = (Vector)call.getObject (2);
>On the Java stored procedure
<<
public class my_procedure
public static void Run(String input_value, Vector buffer)
// ??? Vector buffer = new Vector();
try
while ( true )
buffer.addElement(...) ;
catch(Exception ex) { }
