You're going about this backwords. You do not keep the long-running work on the UI thread in your main form. You move THAT work to a background thread, freeing up the UI thread to handle putting up a "progress" form and updating it.

Because you cannot do UI stuff, like creating forms and showing them, on anything other that the app's startup thread, also known as the UI thread.

It IS possible

abstract class DatabaseWrapper
  // select, insert, update etc


interface ITransactionalDatabaseWrapper
  void StartTransaction();
  void CommitTransaction();
  void RollbackTransaction();
  // same signature select,insert, update etc as DatabaseWrapper


class ExcelWrapper : DatabaseWrapper // non transactional concrete impl of DatbaseWrapper

class SqlDatabaseWrapper : DatabaseWrapper, ITransactionalDatabaseWrapper // transactional impl of DatabaseWrapper

ITransactionalDatabaseWrapper transactionalDb = new SqlDatabaseWrapper(); // there you go.

Date_Time when error occurred :

1) How can I have Log for error in try catch with this informations

1.Error Name :
2.Form Name:
3.Function Name that error occurred :
4.Date_Time when error occurred :

void AddLogEntry(String errorName, String formName, String functionName)
{
  DateTime entryTime = DateTime.Now;
  
  //depending on how you want to save the entry i.e. xml or plain text 
  //append the text in the log file with the entry
  //search in google on how to add text to a text/xml file.
}

void AddLogEntry(Exception ex)
{
  String errorName = ex.message;
  String trace = ex.StackTrace;  //stack trace will give you a brief history on why the error occured
  DateTime entryTime = DateTime.Now;

  //depending on how you want to save the entry i.e. xml or plain text 
  //append the text in the log file with the entry
