Programmatically complete a Workflow in SharePoint

Recently I got a requirement that some of the running workflow in a list need to be closed. I received the clear instruction that, those workflow should not be canceled and status should say 'Approved'. Basically there are some old items in the SharePoint list and these items have a running workflow associated with it. Since those list items are old, there is no point to go through a approval cycle.


After doing a impact analysis, I realized that the workflow status is depending on a task. Therefore if I close the task the associated workflow will complete automatically.


I tried the following piece of code. Here I am trying to update the task associated with the workflow programmatically.

But, to my surprise this is not working. Meaning after completing the task, the status of the workflow does not changed. The OnTaskChanged() method not called within the workflow and the status still showing 'In Progress'. I have to look for an alternative approach.


Finally, I found that the AlterTask of SPWorkflow class is correct way to update a workflow task. The following piece of code solved the purpose.

Changing domain password Programmatically

I was writing a web utility to change the domain password of the user. Here, the user required to enter the current password and the new password.


First error I was encountered - "The password does not meet the password policy requirements. Check the minimum password length, password complexity and password history requirements. (Exception from HRESULT: 0x800708C5)"


Initially I thought that, there is a problem in password strength, so I try may combinations to create the most complex password in the world! But getting the same error.


After doing some research on the internet I found that, "Minimum Password Age" setting needs to set to 0, to allow users set the password many times a day. The default value is 1.

Following are the code snippet used for changing password:

               string Username = strAccountName.Substring(strAccountName.LastIndexOf(@"\") + 1); //Getting account name from the parent application, "Rocky\\Soumyendra"

                string newpwd = txtNewPass.Text;

                string oldpwd = txtOldPass.Text;

                SPSecurity.RunWithElevatedPrivileges(delegate

                {

                    PrincipalContext principalContext = null;

                    principalContext = new PrincipalContext(ContextType.Domain, domain);

                 

                    UserPrincipal user = UserPrincipal.FindByIdentity(principalContext, Username);

                    if (user != null)

                    {

                        user.ChangePassword(oldpwd, newpwd);

                        user.Enabled = true;//By default User is Disabled in Domain

                        user.Save();

                    }

                });

                SendEmail(newpwd);
