Convert C# Struct To Java Using CodePorting Engine

Using CodePorting C#2Java App developers can now migrate C# language constructs even if they don't have a counterpart in java. We have already shown you such example in our previous blogs like converting C# unsigned integer types to java using CodePorting C#2java App. A struct in C# is a user-define type which is declared same as a class, the only difference is that it cannot be inherited from any class and no class can be inherited from it. In this blog we will show you that using CodePorting C#2Java App developers can easily convert C# construct to java in cloud.

See following Example:

C# Code:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

namespace CSharp2Java.Samples.Convert.Structs

    public class StructsExample

        public struct SimpleStruct

            public static SimpleStruct DEFAULT = new SimpleStruct();

        SimpleStruct ss;

        private void Method()

            SimpleStruct simpleStruct = new SimpleStruct();

            Method(simpleStruct);

            Method(ss);

            Method(this.ss);

            Method(SimpleStruct.DEFAULT);

            Method(new SimpleStruct());

            Method(Get());

        private void Method(SimpleStruct s)

        private SimpleStruct Get()

            return ss;

Java Code:

package CSharp2Java.Samples.Convert.Structs;

// ********* THIS FILE IS AUTO PORTED FORM C# USING CODEPORTING.COM *********

import com.codeporting.csharp2java.System.msObject;

import com.codeporting.csharp2java.java.Struct;

public class StructsExample

    public static /*struct*/ class SimpleStruct extends  Struct

         public SimpleStruct(){}

        public static SimpleStruct DEFAULT = new SimpleStruct();

    private SimpleStruct ss = new SimpleStruct();

    private void method()

        SimpleStruct simpleStruct = new SimpleStruct();

        method(simpleStruct.Clone());

        method(ss.Clone());

        method(this.ss.Clone());

        method(SimpleStruct.DEFAULT.Clone());

        method(new SimpleStruct());

        method(get().Clone());

    private void method(SimpleStruct s)

    private SimpleStruct get()

        return ss;

It is clear from the above example that in java a class has been generated by CodePorting C#2Java App for struct defined in C#.

Convert C# Proprties to Java Online using CodePortingC#2Java App

CodePorting C#2Java engine allows all C# developers to automatically convert C# constructs to Java code which you do not find in Java by using auto-generated code. There are properties in C# which provide flexible mechanism to read, write or compute the values of private fields. These properties are also called accessors but there are no such C# equivalent properties in Java. While translating code, CodePorting C#2Java engine intelligently generates Java code to provide same functionality as provided by accessors.

Following example shows migration of C# properties in java:

C# Code:

namespace CSharp2java.Tests.Convert.Properties

    internal class Test151 : Test15

        internal void Method()

            base.Property = 1;

            int i = base.Property;

            base.Property += 20;

            base.Property++;

            --base.Property;

    public class Test15

        public int Property

            get { return mProperty; }

            set { mProperty = value; }

        private int mProperty;

Java code generated by CodePorting:

package CSharp2java.Tests.Convert.Properties;

// ********* THIS FILE IS AUTO PORTED FORM C# USING CODEPORTING.COM *********

class Test151 extends Test15

    void method()

        super.setProperty(1);

        int i = super.getProperty();

        super.setProperty(super.getProperty() + 20);

        super.setProperty(super.getProperty() + 1)/*Property++*/;

        super.setProperty(super.getProperty() - 1)/*--Property*/;

public class Test15

    public int getProperty() { return mProperty; }

    public void setProperty(int value) { mProperty = value; }

    private int mProperty;

The Above Java code replicates the functionality of C# Properties through CodePorting C#2Java Engine.

Automatically Convert C# Unsigned Integer Types to java using CodePorting Engine

We have shown you in previous blog posts that how developers can translate C# properties to java using CodePorting C#2Java App. CodePorting is determined to translate those C# language constructs to java code which are not available in java and this will be achieved by CodePorting C#2Java intelligent engine. Unsigned and signed data types contains same amount of memory in C#. C# provides eight predefined signed and unsigned integer types whereas Java has four signed integer types and no unsigned ones.

See following table:

C# Type	Description	Java Equivalent
sbyte	Signed 8-bit	byte
short	Signed 16-bit	short
int	Signed 32-bit	int
long	Signed 64-bit	long
byte	Unsigned 8-bit	n/a
ushort	Unsigned 16-bit	n/a
uint	Unsigned 32-bit	n/a
ulong	Unsigned 64-bit	n/a

CodePorting C#2Java automatically converts C#'s unsigned integer types to higher signed types. This eliminates the chances of data loss in arithmetic operations.

Following example converts C# unsigned integer type to java:

C# Code:

namespace C#2Java.Samples.Convert.UnsignedArithmetic.UInt

    public class UnsignedArithematic

        void Method(long l, uint u)

            l = MethodReturnsUInt();

            l = u + MethodReturnsUInt();

            u = MethodReturnsUInt();

            l = MethodReturnsUIntArray()[0];

        uint MethodReturnsUInt()

            return 42;

        uint[] MethodReturnsUIntArray()

            uint[] uints = { 42, 127, 155 };

            return uints;

Java Code Generated by CodePorting:

package C#2Java.Samples.Convert.UnsignedArithmetic.UInt;

// ********* THIS FILE IS AUTO PORTED FORM C# USING CODEPORTING.COM *********

public class UnsignedArithematic

    private void method(long l, /*uint*/long u)

        l = (methodReturnsUInt() &amp; 0xFFFFFFFFL);

        l = (u &amp; 0xFFFFFFFFL) + (methodReturnsUInt() &amp; 0xFFFFFFFFL);

        u = methodReturnsUInt();

        l = (methodReturnsUIntArray()[0] &amp; 0xFFFFFFFFL);

    private /*uint*/long methodReturnsUInt()

        return 42;

    private /*uint*/long[] methodReturnsUIntArray()

        /*uint*/long[] uints = { 42, 127, 155 };

        return uints;

It is clear for the above example that CodePorting C#2Java engine intelligently converts the C# unsigned data types to higher signs in java codes to avoid any data loss accuracy.

How to play an mp3 file into a voice call

Hello everyone,

I've been cruising around the net for some help, then I found this forum. Hope some developer guys can help me on this.
I'm working on my own softphone application, but kind of bumping into some trouble when I try to play a sound file (mp3)
into the call. For seeing it more exactly, you can check the website I used as a guideline: http://www.voip-sip-sdk.com/p_345-voip-mp3-playing-voip.html

Is this the best way for sound playing? Or do you have other suggestions?

Thanx

Filtering the XML Node binded with dropdownlist

Hello Friends, I have two DropDownList: 1) CollegeDDL which contains Four static names of the colleges. : Homeopathic Medical College,Physiotherapy College,Institute of Ayurveda,Institute of Business Administration

2) CourseDDL which is bind to CourseDetail.XML.

<InstituteName> Homoeopathic Medical College </InstituteName>

<Course> <CourseName> MD(Repertary) </CourseName> </Course>

<Course> <CourseName> MD(Organon of Medicine) </CourseName> </Course>

<Course> <CourseName> MD(Materia Medica) </CourseName> </Course>

</Institute>

<InstituteName> Physiotherapy College </InstituteName>

<Course> <CourseName> BPT(Sports) </CourseName> </Course>

<Course> <CourseName> BPT(Cardio) </CourseName> </Course>

</Institute>

<InstituteName> Institute of Ayurved </InstituteName>

<Course> <CourseName> BAMS(Nature) </CourseName> </Course>

<Course> <CourseName> BAMS(Plants) </CourseName> </Course>

</Institute>

<InstituteName> Institute of Business Administration </InstituteName>

<Course> <CourseName>BBA(Distance)</CourseName> </Course>

</Institute>

---------------------------------

CourseDetail.XSL

<xsl:template match ="/">

<xsl:apply-templates select ="Institutes/Institute/Course"/>

</Institute>

</xsl:template>

<xsl:template match ="Institutes/Institute/Course">

<xsl:attribute name="CourseName">

<xsl:value-of select="CourseName"/>

</xsl:attribute>

</Institute>

</xsl:template>

</xsl:stylesheet>

------------------------

I have bind Coursedetail.XML to CourseDDL and CourseDetail.XSL (No XPATH Expression)

After doing this, My CourseDDL is correctly filled with all the CourseName value of my XML file.

But now I want to filter the data bound to CourseDDL , based on College Name selected in CollegeDDL.

For Example:Currently my CourseDDL contains all the CourseName : BHMS,MD(Repertary),MD(Organon of Medicine),......,DBM,BBA(Distance).

But when I select "Homoeopathic Medical College" in CollegeDDL , The data bound to CourseDDL should filter accordingly.

It means when I select "Homoeopathic Medical College" , my CourseDDL should Display only that course: BHMS,MD(Repertary),MD(Organon of Medicine),MD(Materia Medica)

------------------------------------

I have tried the following , but could not achieve it.

1) XmlDataSourceCourse.XPath = "/Institutes/Institute[InstituteName='" + CollegeDDL.SelectedItem.Value + "']"

2) XmlDataSourceCourse.XPath = "/Institutes/Institute[InstituteName='" + ddlinstitute.SelectedItem.Value + "']/Course"

3)XmlDataSourceCourse.XPath = "/Institutes/Institute[InstituteName='" + ddlinstitute.SelectedItem.Value + "']/Course/CourseName"

Anybody please help to format correct XPATH Expression to achive this.

c# open explorer window of usb camera

This one is supposed to be simple yet it is a tricky one,

I have a C# app that suppose to find the connected camera and open a windows explorer window for it to browse through the files ... just that

I have tried using wia but failed to understand how i can initiate the explorer window after choosing the active camera...

Can anyone offer a solution ?
Im using this code to select the camera , and dont know what to do next or if there is another solution to this:

private void btnImportFromCamera_Click_1(object sender, EventArgs e) {     wiaDevManager = new WIA.DeviceManagerClass();     CommonDialogClass class1 = new CommonDialogClass();     Device d = class1.ShowSelectDevice(WiaDeviceType.UnspecifiedDeviceType, true, false);     if (d.DeviceID.StartsWith("{6BDD1FC6-810F-11D0-BEC7-08002BE2092F}"))     {         ConnectToCamera();     } }   public bool ConnectToCamera( )   {       try       {           // Device is already connected           if ( wiaDevice != null )               return true;            foreach ( IDeviceInfo DevInfo in new DeviceManagerClass( ).DeviceInfos )           {               // Look for CameraDeviceType devices               if ( DevInfo.Type == WiaDeviceType.CameraDeviceType )               {                   string hop =  DevInfo.DeviceID;                   wiaDevice = DevInfo.Connect( );                    Process.Start(wiaDevice.DeviceID); //Here I want to open the folder (windows explorer ) ....                   return true;               }           }           // Not a still camera           return false;        }       catch ( Exception exp )       {           return false;       }   }

how to fill in html textbox from (c# )windows application

I would like to do the following from a windows application:

1. Open a browser and navigate to a URL.
2. When i am at the correct URL in my browser window, i want to fill in data in the html textboxes on that page from my windows application.
3. When that is done i want to press a button.

Note:
Google Chrome and Mozilla Firefox is currently used in my browser Window.
Internet Explorer(IE)is not used in browser Window.

1.The URL (https://www.exple.com/login.html ) had already opened in anyone web browsers such as Mozilla Firefox and Google Chrome on local System.
It Consists of Two Textboxes such as Username and Password .

2.I Want to fill in data in Username & Password Textbox on Google Chrome/Mozilla Firefox Web Browser.

3.The Input data is taken from C# Windows Application to URL When Clicked Submit Button in Windows Application.

Reading checkbox from gridview

I have a gridview with several columns of data defined within a template like this:

<asp:TemplateField>

<asp:CheckBox Enabled="true" id="Delete_chk" runat="server" >

</asp:CheckBox>

</ItemTemplate>

</asp:TemplateField>

I'm trying to make it possible to check a row item, post back, and delete all checked items.

Initially the checkbox for each row item is unchecked. If I check one and post back, it's still checked on the page, showing that it was maintained in ViewState. When I post back, I use the OnRowDataBound method to look at the current setting of each checkbox with:

bool isChecked = ((CheckBox)xE.Row.FindControl("Delete_chk")).Checked;

It always returns checked=false. If I set checked=true in the template, the same thing happens in reverse: The checkbox always returns checked=true, even when it's been unchecked. So it seems that .NET is holding on to the initial value of the checkboxes and restoring it after each postback.

What do I need to do to make it work?

I have a problem drawing dotted path lines, with evenly spaced dots

I have a problem drawing dotted path lines, with evenly spaced dots:

Can anyone please help with this problem, I want to be able to draw evenly spaced dots along a path line using points in an array, My issue is not with drawing the path line, with dotted lines, this is easy, but with the spacing of the dots at the start and end of the path line.

In the example I have created, I create a square with 4 points and draw a dotted path.

The path starts at the top left corner and finishes back at the top left corner, the dots are evenly placed along the path, except the final dots at the end of the path. (Sometimes the dots are even and other times they are not even).

The shapes I want to draw can be any size and any shape, but I have used a square in this example to show the problem I have.

Can anyone please help me to draw the dots and give the impression that they are even all along the path, for all shapes and sizes.

I have attached an example project or you can download from here:
http://craftysams.co.uk/ItemImages/Website_Craft_Images/dottedline.zip
http://craftysams.co.uk/ItemImages/Website_Craft_Images/dottedline.zip

I have also attached two pictures showing the dotted path line, 1 with even spaced dots at the start / End and another showing the problem I want to resolve, with not evenly spaced dots at the start / end.

The only difference between the two is the point values.

Good: This picture shows a path line that has dots that look even, this is what I want to achieve on all path lines I draw of any size and shape, if you cannot see picture download from here: http://craftysams.co.uk/ItemImages/Website_Craft_Images/good.jpg

Bad: This picture shows a path line that has dots that clash at the start and end of the path line – THIS IS THE PROBLEM I WANT TO RESOLVE, if you cannot see picture download from here: http://craftysams.co.uk/ItemImages/Website_Craft_Images/bad.jpg

Any help much appreciated

I have written the example in vb.net, but I am happy for a resolution in either vb.net or c#.

Thanks

Update div in site.master.

Hi my current system has a screen where the user can input a value into a table using a stored proc. The newly input item is then shown inside a datagrid that is nested within a DIV within the site.master page so it shows on ever webpage. However when on the input screen after the user has clicked the insert button and the item has been saved it looks as if the page is being refreshed but the datagrid within the site.master is not updated.

Is there any way that i can get this to update after the insert has happened without navigating to a different page?

Thanks Boldonglen.

Consume web service behind firewall

Hello

I've followed the article that describes how to consume a webservice behind a firewall but I still get "The remote server returned an error: (407) Proxy Authentication Required" when I'm trying to call a function in my DLL ..

Here is my code:

// Instantiate the WebProxy class
WebProxy myProxy = new WebProxy("http.hiddenproxy.com:80", true);
myProxy.Credentials = new NetworkCredential("username", "password", "domain");

// Instantiate the WebService class
CoCExchange sr = new CoCExchange();
sr.Proxy = myProxy; // Set the proxy to the class
sr.VerifyCoC("1853212"); //Here I get the 407

Can someone please aid me in my eternal searching for an answer?

Best regards

Datagridview Row backcolor problem....

Hi I am facing problem in changing datagridview rows color based on data. but in my datagrid last row containing total so I don't want to apply any background color on it.
I sent the cor or cellRormatting event of datagridview
Here I am using (e.RowIndex!= dgvRoomTypeSeven.Rows.Count-1) to check that it is last row.
but e.RowIndex always gives 0 why?

private void dgvRoomTypeSeven_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)
{

if (e.ColumnIndex != 0 && e.RowIndex!= dgvRoomTypeSeven.Rows.Count-1)
{
if (e.Value.ToString() == "N/A") e.CellStyle.BackColor = Color.Red;
else
e.CellStyle.BackColor = Color.Green;
}
}

Is there any other way?

Run Flash game on PDA with database

We have made a game in flash and backend is SQL server that communicate with dotnet (i.e. aspx page).
This works fine for Computers, but now we need to run the flash game in PDA for that, I want to know how should we communicate the flash game with database. In short, which database server I need and which technology should I usefor that. I have heard about SQLite that work as database for Android progamming.

Please help me.

Logging lock/unlock/logoff/logon events using Windows Service NOT working

I have created a windows service as follows:
_________________________________________________________________
public partial class UserMonitorService : ServiceBase
{

public UserMonitorService()
{
InitializeComponent();
}

void SystemEvents_SessionSwitch(object sender, SessionSwitchEventArgs e)
{
switch (e.Reason)
{
case SessionSwitchReason.SessionLock:
LogEntry(string.Format("Locked at {0}", DateTime.Now));
break;
case SessionSwitchReason.SessionLogoff:
LogEntry(string.Format("Logged Off at {0}", DateTime.Now));
break;
case SessionSwitchReason.SessionLogon:
LogEntry(string.Format("Logged On at {0}", DateTime.Now));
break;
case SessionSwitchReason.SessionUnlock:
LogEntry(string.Format("Unlocked at {0}", DateTime.Now));
break;
default:
break;
}
}

protected override void OnStart(string[] args)
{
LogEntry(string.Format("Service Started at {0}", DateTime.Now));
SystemEvents.SessionSwitch += new SessionSwitchEventHandler(SystemEvents_SessionSwitch);
}

protected override void OnStop()
{
LogEntry(string.Format("Service Stopped at {0}", DateTime.Now));
}

void LogEntry(string message)
{
StreamWriter sw = new StreamWriter("D:/ServiceLog.txt",true);
sw.WriteLine(message);
sw.Close();
}

}
_________________________________________________________________

After installing, it logs Service start and stop messages perfectly, but does not log any of the session related events (so I know that problem is NOT with the logging part here).
Also, when I create a Console Application using the same code and execute it, it logs session lock/unlock events too (so I know that the SessionSwitch handler is also correct).

So what is the mistake here? Am I missing some windows service configuration change that needs to be done here? Thanks in advance.

Using a SqlDataReader from a class.

Hi i am currently teaching myself C# and .NET and i would appreciate some help on this issue from you kind guys.

I have created an aspx page that is going to update the quantity of some text boxes. In the code behind the method calls a class that connects to my SQL server database and returns the values to place in the text boxes in a SQLDataReader.

However the only way i can seem to get the code to work is to not close the connection of the reader or the connection to the database.

Ill post my code below for you guys to see and if you need anymore information please ask.

update.aspx

private void LoadQuantity(int ProdID)
{
SqlDataReader reader2 = Geordie_Jeans.Classes.AdminControl.GetQuant(ProdID);

            int count = reader2.FieldCount;
            while (reader2.Read())
            {
                for (int i = 0; i < count; i++)
                {
                    if (reader2["PROD_SIZE"].ToString() == "L")
                    {
                        txtLQty.Text = reader2["PROD_QUANT"].ToString();
                    }
                    if (reader2["PROD_SIZE"].ToString() == "M")
