Setnamedsubstringvalue | Label Data Sources

Hi,

 

Is it possible to get the names of the data sources on a label?  I have around 50 named data sources and currently 20 label formats but a label will not contain all of them.  If i get get the data sources then i can use SetNamedSubStringValue more effectively.

 

Thanks

 

Richard

  You need to work with the NamedSubStrings collection.  The GetAll() method returns a string that contains the name and value of all data sources on the

  template(s) separated by a delimiter.

   

  // Declare a BarTender application variable 
  BarTender.Application btApp; 
  
  // Declare a BarTender document variable 
  BarTender.Format btFormat; 
  
  // Create a new instance of BarTender 
  btApp = new BarTender.Application();
  
  // Set the BarTender application visible 
  btApp.Visible = true;
  
  // Open a BarTender document 
  btFormat = btApp.Formats.Open("c:\\Format1.btw", false, "");
  
  // Display all of the named data source values 
  MessageBox.Show(btFormat.NamedSubStrings.GetAll(",", ":"));
  
  // End the BarTender process 
  btApp.Quit(BarTender.BtSaveOptions.btDoNotSaveChanges);

  I need to have my label not to remember the embebed data of the previously saved label.

  I pass to the label many named datasources with method SetNamedSubstringValue and some times I need not to pass it any value, but I dont want the label to "remember" last value set in that datasource and just leave it blank.

   

  Is there a command i cound send or some kind of property like "forget last embebed data" in the named datasource I could use?

  Achecac: The problem is that the document would likely be cached in the BarTender process with the named data source already changed from the previous print job.  Either send it a reset value for the named data source that you don't wish to change, else specify the document to be closed (without saving changes) on a per print job basis.  Obviously the latter approach will affect performance.
