Introduction
I have created the named Silver-J project in Visual Studio and used TextEditor as ICSharpCode.TextEditor.dll. You can use any other text editor that you want. In this document we will focus only on creating a project file, reading a project file, and starting processes for compiling a Java source code file. I have defined all the functions in same project without creating other library(dll). There may be some extra, not needed, memory consuming code in it.
To understand this source code, read the Creating Advanced Notepad In C# article.
You can use following articles to create or customize your IDE.
I have used C# programming language to create this IDE but it is possible to create IDE in Java. The benefits of using Java is that you can access all features of it, it also supports many syntax highlighting libraries. C# and Java are syntactically same.
The following article may help you to how to create Tabbed Notepad editor in Java: Creating Advanced Tabbed Notepad In Java.
Requirements
- Visual Studio 2013 Professional
- .NET Framework 4.5
- ICSharpCode.TextEditor.dll library
Files
For this application we need many files where we can store the data.
The following files are stored in the files folder at application location.

VisualFile is the JavaClassFile which is only used to open this file in tab or not when project is opened.
Using the Code
Create Java Project
Add new Windows Form to your project. Here I used New_JavaApplicationProject_Form (New_JavaApplicationProject_Form.cs file) and design it with Project Name textbox, Project Location textbox, Create Java Class checkbox with Browse, Finish & Cancel buttons.
In this file New_JavaApplicationProject_Form.cs we will just read a file \\files\\defaultprojloc.slvjfile.
We will also take input from above form as project name, project location etc.
I have used following variable to store it,
String projloc = ProjectLocationTextBox.Text;
String projfolder = projectfolderlabel.Text;
String projectname = ProjectNameTextBox.Text;
String projectfile;
Now we need to create a folder(directory) same as project name in the read project location folder(projfolder). Once directory is created we will create classes, src, srcclasses named directories in it.
Once project directory created, we need to create project file with file extension as .slvjproj (file name is same as created project name). In that file we will save our project data as defined in above File section. We will save data in XML format.
Following is the function that performs actions.
public void CreateJavaProject()
{
String projloc = ProjectLocationTextBox.Text;
String projfolder = projectfolderlabel.Text;
String projectname = ProjectNameTextBox.Text;
String projectfile;
if (projloc != "" && projectname != "")

First check if project location and project name are not empty strings. Then check whether Create Java Class check box is checked or not. If it is not checked then just create project without .java source file.
First create our java project file (projectfile = projectname + ".slvjproj";). Then we create this file and start to write that file by using the XmlWriter class.
We will write Project Name, Project Location Folder, Project type tags with its read values. Once we done this we need to change the contents of file defaultprojloc.slvjfile
In this file we will save current created/opened project name, location folder, project location file, project type.
If the Create Java Class check box is checked then we will perform all action as above just adding following tags and info to it where fname is entered Java class file name
xmlwriter.WriteElementString("MainClassFile", fname);
xmlwriter.WriteString("\n");
xmlwriter.WriteElementString("JavaClassFile", fname);
xmlwriter.WriteString("\n");
xmlwriter.WriteElementString("VisualFile", fname);
I am keeping track of created project, means if Project is created without creating a java class (means Create Java Class checkbox is unchecked) then CheckProjectType() function return 1 otherwise it returns 2 (variable a is used for this). This if for to create file, adding tabs to tabcontrol, adding projectname & filename to treeview etc. in MainForm.cs file.
Consider you have already designed you main IDE.
Now event for clicking on File->New->New Java Application Project
First show the New java application dialog form.
Download the source code.
ReadCurrentProjectFileName() function returns the string as project file name by reading file \files\defaultprojloc.slvjfile by reading tag CurrentProjectFileName.
If CheckProjectType() is 2 then we will create create a file by reading JavaClassFile tag text from current project, add tab to tabcontrol with control of texteditor, changing text of MainForm, adding projectname & file names to ProjectExplorerTreeView and then we will save that file.
private void File_New_JavaApplicationProjectMenuItem_Click(object sender, EventArgs e)

New_JavaApplicationProject_Form njap = new New_JavaApplicationProject_Form(this, ProjectExplorerTreeView, myTabControl);

AddFilesToProjectExplorerTreeView();
WriteCurrentFileNames();
CopyAllSourceFilesToSRCFolder();
UpdateWindowsList_WindowMenu();
SetVisibilityOfToolStripButtons();
myTabControl_SelectedIndexChanged(sender, e);
}
}
If njap.isFinished()==true it will call all functions that we need to change or modify the IDE such as adding files to project explorer tree view, set visibility of toolstrip buttons, changing text of FilenameToolStripLabel to current opened file name.
WriteCurrentFileNames() this function reads all files from current opened project file name & write those file name to \files\files.slvjfile for save operation.CopyAllSourceFilesToSRCFolder() this function copies the all files from srcclasses to src folder without including .class file.UpdateWindowsList_WindowMenu() this function checks tabs in tabcontrol and add those tab texts to Window menu by creating new menu items for selecting each tab by clicking on that menu item.
What we are doing here is that,
In New_JavaApplicationProject_Form.cs file,we are creating project file(<project_name>.slvjproj), writing project data to this file, creating directories (Project named directory in that classes,src, srcclasses directories).
In MainForm.cs file, we are reading created project file(<project_name>.slvjproj), adding tabs to tabcontrol with text of created filename, creating that file and writing that file, and also adding contents to ProjectExplorerTreeview. Where tab is MyTabPage which is going to add to tabcontrol. (see MyTabPage.cs)
See following article for better understanding to add tabs: Creating Advanced Notepad In C#
Same actions to create New Java Applet Project, only one extra content to create means index.html file.
New Java Class
Now we need a class form that create a java class. To create class a java project must created or opened in IDE. The following is the form that create or add java class to current opened project in the application.
In file New_Class_Form.cs, we are reading Class Name, also reading Modifiers, Super Class etc. Once the Finish button is clicked, the tab is added to tabcontrol with same as class name by just adding .java to the end of it, and returning this filename with full path (getCreatedFileName() function).
In MainForm.cs file, in File_New_ClassMenuItem_Click() event, we will get this file name (getCreatedFileName()) , read contents from texteditor which is added to tabcontrol by New_Class_Form.cs file, creating this file and writing this contents to file using StreamWriter class.
Finally adding tag <JavaClassFile> and <VisualFile> with text as created filename. Also adding <MainClassFile> tag, this tag text is read when we want to compile a file.

New Package - Here we will create a folders in the project folder. When aaa.bbb.ccc package name is entered then we will replace . to \,(aaa\bbb\ccc) and will create these directories in current opened project location folder and also will create java class in aaa\bbb\ccc folder.
For other options like,
File->New->Interface, File->New->Enums
File->New->HTML File, File->New->CSS File
File->New->Text File, File->New->JavaScript File
File->New->SQL File, File->New->XML File
File->New->New File
Are same code as create New Java Class, just to create files with their own extensions.
Are same code as create New Java Class, just to create files with their own extensions.
Open Project: (File->Open Project) This is nothing but the read file(.slvjproj) from OpenFileDialog, read contents from it, and perform actions about it such as adding application form text to project name text, adds tabs to tabcontrol by getting files by tags
<JavaClassFile>,<HTMLFile> etc. Once project is opened adding Project Type, ProjectName, Project Location Folder to \files\defaultprojloc.slvjfile.
OpenFiles: (File->Open Files) This is same as above(Open Project) only to read files, adding their names to ProjectExplorerTreeView, opening those files on tabs and adding all file names with their full path to \files\files.slvjfile.
Save: (File->Save) For saving a opened file on tab, I am using FilenameToolStripLabel to show/store current opened file name full path on tab.
I am checking FilenameToolStripLabel contains ‘\’ or not, if it contains then read texteditor contents from current selected tab & write it to file from FilenameToolStripLabel.Text or here you can read files\files.slvjfile where contains all current opened project files with their full path.
Save All : (File->Save All) For this, iam reading a file \files\files.slvjfile, comparing each tab with each file name read from files.slvjfile, if it matches then setting that tab to selected, save that file by reading current set tab texteditor with filename
Load Sample Project
As every IDE provides some sample projects, here we will provide following sample projects.
First design your sample project form for selecting what kind of project want to create.
Create sample project is nothing but to create a Project file(.slvjproj), Project directory, creating sub directories in it (src, classes, srcclasses), creating project files (.java) in those directories, adding this created project information to \files\defaultprojloc.slvjfile & just call OpenProject function with created project file name.
These project files are located at Samples folder.
First lets define variables to store what files need to be read from Samples folder.
Here I defined notepad_files (notepad source file), notepad_2 (source file name we want to create in/as project)
String[] notepad_files = {
Application.StartupPath+"\\Samples\\Notepad\\Notepad.slvjfile"
};
String[] notepad_2 ={
"Notepad.java"
};
String defaultprojfilepath = Application.StartupPath + "\\files\\defaultprojloc.slvjfile";
public String ProjectLocaionFoder()
{
String projectfolder = "";
using (XmlReader reader = XmlReader.Create(defaultprojfilepath))
{
while (reader.Read())
{
if (reader.IsStartElement())
{
switch (reader.Name.ToString())
{
case "DefaultProjectLocation":
projectfolder = reader.ReadString();
break;
}
}
}
}
return projectfolder;
}
String selected_item = listBox1.SelectedItem.ToString();
String projectfolder = ProjectLocaionFoder();
listBox1 is the control added to form (see above image). selected_item contains selected sample project name and projectfolder contains users project folder.
if (selected_item == "Notepad")
{
project_name = "Notepad";
String directory = projectfolder + "\\Notepad";
String projectfile = "Notepad.slvjproj";
if (Directory.Exists(directory))
{
MessageBox.Show("The selected project is already exists in current location", "Error............");
}
else
{
Directory.CreateDirectory(directory);
if (Directory.Exists(directory))
{
project_folder = directory;
project_file = directory + "\\" + projectfile;
}
if (File.Exists(notepad_files[0]))
{
String filename = notepad_files[0];
String fname = filename.Substring(filename.LastIndexOf("\\") + 1);
fname = fname.Remove(fname.Length - 9);
fname = fname + ".java";
if (Directory.Exists(directory))
{
String src = directory + "\\src";
String srcclasses = directory + "\\srcclasses";
String classes = directory + "\\classes";
Directory.CreateDirectory(src);
Directory.CreateDirectory(srcclasses);
Directory.CreateDirectory(classes);
String content = "";
content = File.ReadAllText(notepad_files[0]);
if (Directory.Exists(srcclasses))
{
StreamWriter strw = new StreamWriter(File.Create(srcclasses + "\\" + fname));
strw.Write(content);
strw.Close();
strw.Dispose();
}
using (XmlWriter xmlwriter = XmlWriter.Create(directory + "\\" + projectfile))
{
xmlwriter.WriteStartDocument();
xmlwriter.WriteStartElement("SilverJProject");
xmlwriter.WriteString("\n");
xmlwriter.WriteComment("Silver-J (1.0) Java Application Project");
xmlwriter.WriteString("\n");
xmlwriter.WriteElementString("ProjectName", "Notepad");
xmlwriter.WriteString("\n");
xmlwriter.WriteElementString("ProjectLocationFolder", directory);
xmlwriter.WriteString("\n");
xmlwriter.WriteElementString("ProjectLocationFile", directory + "\\" + projectfile);
xmlwriter.WriteString("\n");
xmlwriter.WriteElementString("ProjectType", "ApplicationType");
xmlwriter.WriteString("\n");
xmlwriter.WriteElementString("MainClassFile", directory + "\\srcclasses" + "\\" + notepad_2[0]);
xmlwriter.WriteString("\n");
xmlwriter.WriteElementString("JavaClassFile", directory + "\\srcclasses" + "\\" + notepad_2[0]);
xmlwriter.WriteString("\n");
xmlwriter.WriteElementString("VisualFile", directory + "\\srcclasses" + "\\" + notepad_2[0]);
xmlwriter.WriteEndElement();
xmlwriter.WriteEndDocument();
xmlwriter.Close();
}
}
}
is_project_created = true;
}
}
Here we are just performing actions same as creating new Java application project with Create Java Class checkbox is checked.
Compile & Run
Compiling using IDE means run commands through processes. But here to compile a java source file we dont need any window to show, we just need output of compilation such as errors and warnings. It is easy to create process. We need boolean value whether processes is started or not for compilation.
Consider you are compiling your java programs using cmd, same we are doing here.
e.g: cd C:\MyJava\Hello
javac.exe HelloWorld.java
Download the source code.
See following code:
Where EXE is application javac.exe with full path
WorkingDirectory is our source file directory (srcclasses)(above e.g C:\MyJava\Hello)
FileName is our main java source file which we want to compile (HelloWorld.java)
We need only one java source file to compile, you can provide more files.
The main source file is saved in the project file(.slvjproj) with tag <MainClassFile>. This file can be changed by going to Run->Main Class
public bool Compile(String EXE, String WorkingDirectory, String FileName)
{
bool processStarted = false;
if (File.Exists(EXE))
{
process.StartInfo.FileName = EXE;
process.StartInfo.Arguments = FileName;
process.StartInfo.WorkingDirectory = WorkingDirectory;
process.StartInfo.CreateNoWindow = true;
process.StartInfo.ErrorDialog = false;
process.StartInfo.UseShellExecute = false;
process.StartInfo.RedirectStandardOutput = true;
process.StartInfo.RedirectStandardError = true;
processStarted = process.Start();
}
else
{
MessageBox.Show("Unable to compile java file. Check your Java Path settings: Current Java Path : ");
}
return processStarted;
}
public void CompileJava(String file, String jdkpath)
{
String mystr = file;
if (mystr.Contains(".java"))
{
mystr = mystr.Remove(mystr.Length - 5);
}
if (this.Compile(jdkpath + "\\javac.exe", Path.GetDirectoryName(file), Path.GetFileName(file)))
{
ErrorReader = process.StandardError;
string response = ErrorReader.ReadToEnd();
if (response != "")
{
ErrorTextBox.Text = response;
if (showErrorDialog == true)
{
MessageBox.Show("" + response, "Errors");
}
}
else if (response == "")
{
ErrorTextBox.Text = "Program Compiled Successfully.................!";
}
else if (response.Contains("uses or overrides a deprecated API."))
{
ErrorTextBox.Text = "Program Compiled Successfully.................!";
}
else
{
ErrorTextBox.Text = "Program Compiled Successfully.................!";
}
}
else if (File.Exists("" + mystr + ".class"))
{
ErrorTextBox.Text = "Program Compiled Successfully.................!";
}
if(myTabControl.TabCount>0)
{
if(myTabControl.SelectedTab.Text.Contains(".java"))
{
String compilejavafilename = myTabControl.SelectedTab.Text;
if (ErrorTextBox.Text.Contains(compilejavafilename))
{
int select_index = myTabControl.SelectedIndex;
var texteditor = (TextEditorControl)myTabControl.TabPages[select_index].Controls[0];
RichTextBox rtb = new RichTextBox();
rtb.Text = texteditor.Text;
for(int i=0;i<rtb.Lines.Length;i++)
{
if(ErrorTextBox.Lines[0].Contains(i.ToString()))
{
texteditor.ActiveTextAreaControl.TextArea.Caret.Line = i-1;
}
}
}
}
}
}
showErrorDialog is to hold whether to show dialog after clicking on compile menu item. If an error is found then show it, and set caret to that error line number.
You know how to run Java programs on cmd.
First you compile Java source file, it will create .class file by going to the location folder. And then you run that class file using java.exe command.
e.g: cd C:\MyJava\Hello
java.exe HelloWorld.class
Instead of using only java.exe, I am using full path of java.exe file(jdk_path\bin\java.exe) as a string.
String projectlocationfolder = getCurrentProjectLocationFolder();
if (Directory.Exists(projectlocationfolder + "\\srcclasses"))
{
if (filename.Contains(".java"))
{
String ffname = filename.Remove(filename.Length - 5);
ffname = ffname + ".class";
if (File.Exists(ffname))
{
ProcessStartInfo ProcessInfo;
String javapath = "\"" + jdkpath + "\\java.exe" + "\"";
String getfilename = filename.Substring(filename.LastIndexOf("\\") + 1);
String fname = "";
if (getfilename.Contains(".java"))
{
fname = getfilename.Remove(getfilename.Length - 5);
}
ProcessInfo = new ProcessStartInfo("cmd.exe", "/K" + " cd/ && cd " + workingDirectory + " && " + javapath + " " + fname);
ProcessInfo.CreateNoWindow = true;
ProcessInfo.UseShellExecute = true;
Process.Start(ProcessInfo);
}
}
}
ProcessInfo = new ProcessStartInfo("cmd.exe", "/K" + " cd/ && cd " + workingDirectory + " && " + javapath + " " + fname);
This line run the program. First it starts the cmd.exe with command cd/.
Then goes to project directory(workingDirectory(srcclasses)) by using cd.
Then call java.exe filename full path with .class filename.
Same for Run with Parameter option just adding those parameters after fname.
Same for Run Applet option only just to use appletviewer.exe with HTML source file.
Build Executable Jar
To create executable jar file we need a manifest file (manifest.mf). that file contain following contents.
Manifest-Version: 1.0
Ant-Version: Apache Ant 1.9.4
Created-By: 1.8.0_25-b18 (Oracle Corporation)
Class-Path:
X-COMMENT: Main-Class will be added automatically by build
Main-Class:
Main-Class:
Where Main-Class: should contain mailclass filename(only filename without any file extension).
Created-By: is the JDK version.
To create jar file using cmd,
First go to working directory.
jar.exe cmf <manifest_file> <outputfile> <class_files>
e.g:
jar.exe cmf manifest.mf Hello.jar HelloWorld.class
In Run_BuildMenuItem_Click(), I have used a textbox to paste all .class files in it and use textbox. Text as class files. It will not add .java source files.
It also adds directories to jar file by adding directory names to textbox.
The process is same as running java programs, just changing in commands, inputs & arguments.
Once jar file is created, we will create a build folder in project location folder & copy created jar file there.
private void Run_BuildMenuItem_Click(object sender, EventArgs e)
{
String projectfolderpath = getCurrentProjectLocationFolder();
if (projectfolderpath != "")
{
if (Directory.Exists(projectfolderpath + "\\srcclasses"))
{
String mainclass = getMainClassFileName();
String mnclass = mainclass.Substring(mainclass.LastIndexOf("\\") + 1);
mnclass = mnclass.Remove(mnclass.Length - 5);
String maintexttomanifest = "Manifest-Version: 1.0"
+ "\nAnt-Version: Apache Ant 1.9.4"
+ "\nCreated-By: 1.8.0_25-b18 (Oracle Corporation)"
+ "\nClass-Path: "
+ "\nX-COMMENT: Main-Class will be added automatically by build"
+ "\nMain-Class: " + mnclass
+ "\nMain-Class: " + mnclass;
String manifestfile = projectfolderpath + "\\srcclasses\\mainclass.mf";
StreamWriter strw = new StreamWriter(manifestfile);
strw.Write(maintexttomanifest);
strw.Close();
strw.Dispose();
if (File.Exists(manifestfile))
{
String srcclassesfolderpath = projectfolderpath + "\\srcclasses";
List<string> packagenameslist = getPackageNamesList();
TextBox textbox = new TextBox();
string[] files = Directory.GetFiles(srcclassesfolderpath);
foreach (string filePath in files)
{
if (Path.GetExtension(filePath) != ".java" && Path.GetExtension(filePath) != ".mf")
{
textbox.Paste(" " + Path.GetFileName(filePath));
}
}
RichTextBox rtb = new RichTextBox();
String[] dirs = Directory.GetDirectories(srcclassesfolderpath);
foreach (String packagefolder in packagenameslist)
{
rtb.Text = rtb.Text.Insert(rtb.SelectionStart, "" + packagefolder + " ");
}
foreach (String dirsname in dirs)
{
String dirs2 = dirsname.Substring(dirsname.LastIndexOf("\\") + 1);
if (rtb.Text.Contains(dirs2)) { }
else
{
textbox.Paste(" " + dirs2 + "* ");
}
}
if (File.Exists(manifestfile))
{
String jarfilepath = "\"" + getJDKPath() + "\\jar.exe" + "\"";
String prjfolder = getCurrentProjectLocationFolder() + "\\srcclasses";
String manifestfilename = manifestfile.Substring(manifestfile.LastIndexOf("\\") + 1);

if (Directory.Exists(buildfolder))

try

Appearance
IDE also has different themes. Here I am providing Default, System, Light, Dark & Night appearances.
Appearance means just changing colors of the components.
For MenuStrip and ToolStrip we need to write code for rendering their appearance by drawing. These renderer classes are defined in MyRenderer.cs file.
I have created MyMenuStripZ, MyToolStripZ classes inheriting MenuStrip and ToolStrip and adding renderers to it from file MyRenderer.cs.
Here the code that set Night theme to IDE
if(type=="Night")
{
MyMenuStripZ.Renderer = new NightMenuRenderer();
textEditorContextMenuStrip.Renderer = new NightMenuRenderer();
ProjectExplorerTreeViewContextMenuStrip.Renderer = new NightMenuRenderer();
myTabControlContextMenuStrip.Renderer = new NightMenuRenderer();

myTabControl.DrawMode = TabDrawMode.OwnerDrawFixed;
myTabControl.Transparent1 = 255;
