  I have a problem with passing a custom sql command, I don't know how to pass parameters to tabledatasource selectcommand as it can be done with oledbcommand.parameters.add(.....), working without that is handling error when I the where condition data has an apostrophy.
  
  Example: table.selectcommand="select * from listetous where objsup='l'homme'" with oledbcommand it works when I use parameter :
  oledbcommand.commandtext= ="select * from listetous where objsup=a"
  oledbcommand.parameters.add("a",oledbvarchar,255).value= "l'homme"
  
  Can someone help me showing me how to use parameters with tabledatasource?
  
  thank you!!!

  
  I have gotten the solution :
  
  what I did was to declare a fastreport commandparameter, I passed the value to that parameter and added the parameter to the tabledatasource paramtercollection
  
  
  

  'Declaration of the parameter
  dim p as new fastreport.commandparameter
  'name of the parameter
  p.name=a
  'parameter data type 
  p.datatype = oledb.datatype.varchar
  'passing a value to the parameter
  p.value ="l'homme"
  'defining the size of data
  p.size =50
  
  table.parameters.add(p)

  using FastReport.Data;
  
  report1.Load("report1.frx");
  TableDataSource table = report1.GetDataSource("Table1") as TableDataSource;
  table.SelectCommand = "SELECT * FROM CUSTOMERS";
  report1.Show();
