Add a command sample in C#

Table of Contents

Create C# class with Visual Studio

  • Open your project in Visual Studio
  • Select your project and click on
  • Add -> New Item...
  • Select Visual C# Items -> Class
  • Rename your class here with EwUsersCommandX

Click OK.

Create a new Command

For create a new command derive your EwUsersCommandX class with the EwCommandX interface.

public class EwUsersCommandX : EwCommandX
{

After that you must override 4 functions.

The Second step is to:

  • give a unique name of the command.
  • give a description of the command.
  • give a flag instruction (see help for more information).
public string getName(out EwErrorCode errorCode)
{
errorCode = EwErrorCode.EW_NO_ERROR;
return "HelloWorld";
}
public string getDescription(out EwErrorCode errorCode)
{
errorCode = EwErrorCode.EW_NO_ERROR;
return "An Hello World Message";
}
public int getFlags(out EwErrorCode errorCode)
{
errorCode = EwErrorCode.EW_NO_ERROR;
return (int) (EwCommandType.kCommandSession | EwCommandType.kCommandNoUndoMarker);
}

The next step is to code the goal of your command.

public EwErrorCode execute(EwCommandContextX commandContextX)
{
// your function here: Sample
EwErrorCode ewErrorCode = EwErrorCode.EW_UNDEFINED_ERROR;
if (mEwApplicationX == null) // mEwApplicationX declare previously see
return ewErrorCode;
EwDialogTaskX ewDialogTask = mEwApplicationX.getEwDialogTask(out ewErrorCode);
if ((ewErrorCode != EwErrorCode.EW_NO_ERROR) || (ewDialogTask == null))
return ewErrorCode;
ewDialogTask.setContent("Hello World.");
ewDialogTask.addButton("Ok", 1);
ewDialogTask.show(out ewErrorCode);
return ewErrorCode;
}

Here is a C# example of implementation:

using System.Runtime.InteropServices;
using EwAPI;
namespace UsersCommand
{
[ComVisible(true)]
public class EwUsersCommandX : EwCommandX
{
public IEwApplicationX mEwApplicationX = null;
public string getName(out EwErrorCode errorCode)
{
errorCode = EwErrorCode.EW_NO_ERROR;
return "HelloWorld";
}
public string getDescription(out EwErrorCode errorCode)
{
errorCode = EwErrorCode.EW_NO_ERROR;
return "An Hello World Message";
}
public int getFlags(out EwErrorCode errorCode)
{
errorCode = EwErrorCode.EW_NO_ERROR;
return (int) (EwCommandType.kCommandSession | EwCommandType.kCommandNoUndoMarker);
}
public EwErrorCode execute(EwCommandContextX commandContextX)
{
// your function here: Sample
EwErrorCode ewErrorCode = EwErrorCode.EW_UNDEFINED_ERROR;
if (mEwApplicationX == null) // mEwApplicationX declare previously see
return ewErrorCode;
EwDialogTaskX ewDialogTask = mEwApplicationX.getEwDialogTask(out ewErrorCode);
if ((ewErrorCode != EwErrorCode.EW_NO_ERROR) || (ewDialogTask == null))
return ewErrorCode;
ewDialogTask.setContent("Hello World.");
ewDialogTask.addButton("Ok", 1);
ewDialogTask.show(out ewErrorCode);
return ewErrorCode;
}
public void test()
{
mEwApplicationX.runCommand("HelloWorld");
}
}
}

How to use a new Command

Now it's time to add the new command to

public void addCommand()
{
EwErrorCode ewErrorCode = EwErrorCode.EW_UNDEFINED_ERROR;
IEwCommandManagerX ewCommandManager = mEwApplicationX.getEwCommandManager(out ewErrorCode);
if ((ewErrorCode != EwErrorCode.EW_NO_ERROR) || (ewCommandManager == null))
return;
EwUsersCommandX ewCommand = new EwUsersCommandX();
ewErrorCode = ewCommandManager.addCommand(ewCommand);
}

And to test it.

public void test()
{
mEwApplicationX.runCommand("HelloWorld");
}

To knowing the list of parameters of the last command

public void getParameterList()
{
EwErrorCode ewErrorCode = EwErrorCode.EW_UNDEFINED_ERROR;
IEwCommandManagerX ewCommandManager = mEwApplicationX.getEwCommandManager(out ewErrorCode);
if ((ewErrorCode != EwErrorCode.EW_NO_ERROR) || (ewCommandManager == null))
return;
dynamic vArray = ewCommandManager.getParameterList(out ewErrorCode);
int iSize = vArray.Length;
for(int i = 0; i < iSize; i++)
{
string strParam = vArray[i];
}
}

And to remove the command

public void removeCommand()
{
EwErrorCode ewErrorCode = EwErrorCode.EW_UNDEFINED_ERROR;
IEwCommandManagerX ewCommandManager = mEwApplicationX.getEwCommandManager(out ewErrorCode);
if ((ewErrorCode != EwErrorCode.EW_NO_ERROR) || (ewCommandManager == null))
return;
ewErrorCode = ewCommandManager.removeCommand("HelloWorld");
}

Here is a C# example of use:

using System;
using System.Runtime.InteropServices;
using EwAPI;
namespace UsersCommand
{
public class EwUserCommandManagerX
{
public void addCommand()
{
EwErrorCode ewErrorCode = EwErrorCode.EW_UNDEFINED_ERROR;
IEwCommandManagerX ewCommandManager = mEwApplicationX.getEwCommandManager(out ewErrorCode);
if ((ewErrorCode != EwErrorCode.EW_NO_ERROR) || (ewCommandManager == null))
return;
EwUsersCommandX ewCommand = new EwUsersCommandX();
ewErrorCode = ewCommandManager.addCommand(ewCommand);
}
public void removeCommand()
{
EwErrorCode ewErrorCode = EwErrorCode.EW_UNDEFINED_ERROR;
IEwCommandManagerX ewCommandManager = mEwApplicationX.getEwCommandManager(out ewErrorCode);
if ((ewErrorCode != EwErrorCode.EW_NO_ERROR) || (ewCommandManager == null))
return;
ewErrorCode = ewCommandManager.removeCommand("HelloWorld");
}
public void getParameterList()
{
EwErrorCode ewErrorCode = EwErrorCode.EW_UNDEFINED_ERROR;
IEwCommandManagerX ewCommandManager = mEwApplicationX.getEwCommandManager(out ewErrorCode);
if ((ewErrorCode != EwErrorCode.EW_NO_ERROR) || (ewCommandManager == null))
return;
dynamic vArray = ewCommandManager.getParameterList(out ewErrorCode);
int iSize = vArray.Length;
for(int i = 0; i < iSize; i++)
{
string strParam = vArray[i];
}
}
}
}
