Generate Id In Excel

A CSharp library to generate completely random short id's. They can be used as primary keys or unique identifiers. This library is different in that you can specify the length of the id's generated. I have tested the application generating 180000 id's without duplicates.

An ID must be a value, not a formula, though, so copy (Ctrl+C) and paste as plain text (Shift+Ctrl+V) the result of the formula calculation into the cell meant to contain the new ID. That's all there is to it! For example, to generate a set of new IDs in column A for rows 2 through 10: Copy (Ctrl+C) the formula above. Aug 19, 2019 3. Once it locates the idrsa.pub key created on the local machine, it will ask you to provide the password for the remote account. Type in the password and hit Enter. Once the connection has been established, it adds the public key on the remote server. This is done by copying the /.ssh/idrsa.pub file to the remote server’s /.ssh. Oct 18, 2017 Open this page and sign into your Apple ID. Now under the Security section look for ‘Generate Password’ option, right under App-Specific Passwords heading. Enter a password label. It is a good idea to use the name of the app or service you are creating the app-specific password for so it is easier to recognize it later. Generate (Fake) South-African ID Numbers. Year of Birth. Month of Birth. Day of Birth. Show expert options. Hint: submit the form to get an ID. To Generate an SSH key in Windows 10, Open a new command prompt. Type ssh-keygen and hit the Enter key. The app will ask for the save location, offering C:usersyour user name.sshidrsa by default. Next, you will be prompted to enter a passphrase. You can just hit the Enter key to skip it. Finally, you will see the fingerprint for your key. Generate-id Function.; 2 minutes to read; In this article. Returns a string that uniquely identifies the node in the node-set argument that is first in document order. String generate-id(node-set?) Remarks. The unique identifier must consist of ASCII alphanumeric characters and must start with an alphabetic character. If you're okay with gaps in your incrementing id, and you're okay with it only roughly corresponding to the order in which the rows were added, you can roll your own: Create a separate table called NextIdTable, with one primary key (numeric), call it Counter. Each time you want to generate a new id, you would do the following.

How to use

To make use of the shortid, add it to your project via the Nuget package manager UI or console via this command:

Add the following using command to the top of your csharp code file:

This gives your code access the classes and methods of the shortid namespace.

To generate a unique id of any length between 7 and 14, you call the Generate method without parameters.

If you want to include numbers in the generated id, then you call the Generate method with a boolean indicating your preference.

If you do not want special characters i.e _ and - in your generated id, then call the Generate method with two boolean parameters, the first indicating whether or not you want numbers and the second indicating whether or not you want special characeters.

If you want to specify the length of the generated id, call the Generate method with an integer parameter which is the desired length.

If you want to control the type of id generated by specifying whether you want numbers, special characters and the length, call the Generate method and pass three parameters, the first a boolean stating whether you want numbers, the second a boolean stating whether you want special characters, the last a number indicating your length preference.

NOTE: v2.0.0 introduced a change that prevents lengths of less than 7

Customize ShortId

ShortId has several features that help with customizing the ids generated. Characters sets can be introduced and the random number generator can be seeded.

To change the character set in use, run the following:

NOTE: the new character set must not be null, an empty string or whitespace. Also, all whitespace characters would be removed, finally the character set cannot be less than 20 characters.

ShortId also allows the seed for the random number generator to be set.

To set the seed, run the following:

Finally, ShortId allows for all customizations to be reset using the following:

Suppose this is my code for Complaint Registration, then where should i put that code.

public class ComplaintServlet extends HttpServlet { Connection con; PreparedStatement ps = null; public void init(ServletConfig config) throws ServletException { con = DatabaseConnection.getConnection(); } public void destroy() { try { ps.close(); DatabaseConnection.close(con); } catch (SQLException e) { e.printStackTrace(); } } public void doGet(HttpServletRequest req,HttpServletResponse res) throws ServletException { try{ doPost(req,res); } catch(IOException e) { } } protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { try { int cid=Integer.parseInt(request.getParameter('cid')); System.out.println('cid = ' + cid); int con_id=Integer.parseInt(request.getParameter('con_id')); System.out.println('con_id = ' + con_id); String Complaint_Type=request.getParameter('Complaint_Type'); System.out.println('Complaint_Type = ' + Complaint_Type); int nocomp=Integer.parseInt(request.getParameter('nocomp')); System.out.println('nocomp = ' + nocomp); int noprbm=Integer.parseInt(request.getParameter('noprbm')); System.out.println('noprbm= ' + noprbm); String btnSubmit=request.getParameter('btnSubmit'); System.out.println('btnSubmit= ' + btnSubmit); if(btnSubmit.equals('SUBMIT')) { String sql = 'Insert into RegisterComplaint Values(?,?,?,?,?)'; try { ps = con.prepareStatement(sql); ps.setInt(1, cid); ps.setInt(2, con_id); ps.setString(3, Complaint_Type); ps.setInt(4, nocomp); ps.setInt(5, noprbm); ps.executeUpdate(); } catch (SQLException e) { e.printStackTrace(); } response.sendRedirect('SuccessfulComplaintRegister.jsp'); } } catch (Exception ex) { System.out.println(ex.getMessage()); } } }

You can put this code anywhere see for your edited servlet.
see for the generateId() method and randomId variable. use randomId variable where you want to use.

public class ComplaintServlet extends HttpServlet { Connection con; PreparedStatement ps = null; public int generateId(){ int randomId = 0; Random rand = new Random(); for (int j=0;j < 10;j++) { randomId = rand.nextInt(); } return randomId; } public void init(ServletConfig config) throws ServletException { con = DatabaseConnection.getConnection(); } public void destroy() { try { ps.close(); DatabaseConnection.close(con); } catch (SQLException e) { e.printStackTrace(); } } public void doGet(HttpServletRequest req,HttpServletResponse res) throws ServletException { try{ doPost(req,res); } catch(IOException e) { } } protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { try { int cid=Integer.parseInt(request.getParameter('cid')); System.out.println('cid = ' + cid); int con_id=Integer.parseInt(request.getParameter('con_id')); System.out.println('con_id = ' + con_id); String Complaint_Type=request.getParameter('Complaint_Type'); System.out.println('Complaint_Type = ' + Complaint_Type); int nocomp=Integer.parseInt(request.getParameter('nocomp')); System.out.println('nocomp = ' + nocomp); int noprbm=Integer.parseInt(request.getParameter('noprbm')); System.out.println('noprbm= ' + noprbm); String btnSubmit=request.getParameter('btnSubmit'); System.out.println('btnSubmit= ' + btnSubmit); int randomId = generateId();//you can use this randmId anywhere you want to. if(btnSubmit.equals('SUBMIT')) { String sql = 'Insert into RegisterComplaint Values(?,?,?,?,?)'; try { ps = con.prepareStatement(sql); ps.setInt(1, cid); ps.setInt(2, con_id); ps.setString(3, Complaint_Type); ps.setInt(4, nocomp); ps.setInt(5, noprbm); ps.executeUpdate(); } catch (SQLException e) { e.printStackTrace(); } response.sendRedirect('SuccessfulComplaintRegister.jsp'); } } catch (Exception ex) { System.out.println(ex.getMessage()); } } }

Prashant, I'm sure you're trying to be helpful, but please DontBeACodeMill (←click).

Generate Key Pair

Also, your method (even corrected) mystifies me:
1. Why create a new Random object for each invocation? Completely unnecessary.
2. Why loop 10 times?
@Mohini:
1. If this ID is related to a database table, then I would strongly urge you to use a sequence number obtained from the DB itself.
2. If not, there are a couple of Java classes for obtaining unique (or near-unique) IDs: java.rmi.server.UID and java.util.UUID. I suggest you also look at them before ploughing ahead too soon.

prashant chindhade, you should provide the hint to the logic and let others try to figure out the logic. So, don't provide the full implementations
is it ok?
I have always used
or DatabaseConnection is a separate class created by you?

1. If this ID is related to a database table, then I would strongly urge you to use a sequence number obtained from the DB itself

I agree with Winston Gutkowski
