java - Display Loop Results In TextArea -

-

I have programmed a device to check PDF files. I PDF files go through a check method: if If there is an error, it will be displayed on which page it is on. PDF files are listed in the JTable .

When I right-click on a PDF file in the table, a text box will appear with an error message.

I use the textArea.append (text) . But it shows me all the errors of all PDF files. I just want to see the error of selected PDFs. 

 for  (int page number = 1; pg; p; pdf.getPages (); pageNo ++) {try {PCProperty content = pdf.getContent (no page, content configuration option. NON); If (content == zero) {error = "error"; }} Hold (PDFDocumentException exception) {error = "Error"; TextArea.append ("Failed to read content on page" + Page no + "\ n"); }}

For each new document, you empty Or for an empty string Alternatively, attachments () checks the name of the document in order to maintain a visual separator and running history of documents: 

  textArea.append ("** ** * "+ Pdf.getName () +" \ n ");

c++ - Cassandra datastax cpp driver - avoiding unnecessary copies -

-
I use the following method to create my insert statement for Cassandra (using datastax cpp driver) : ssStmt1 & lt; & Lt; "Insert some table (...) value (....)" string sStatement1 = ssStmt1.str (); Castestring cass1 = cass_string_init (sStatement1.c_str ()); CassStatement * pStmt1 = cass_statement_new (cass1, 0); I have also tried the following: CassString cass1 = cass_string_init ("Enter some table (id, date, c) value (? ,?,?); "); CassStatement * pStmt1 = cass_statement_new (cass1, 3); Cass_statement_bind_uuid (pStmt1, 0, uuidKey); Cass_statement_bind_int64 (PSTMT1, 1, timestamp); Cass_statement_bind_string (pStmt1, 2, sSomething); The first pattern works with mixed keys, the second is not. The key has a timestamp and a UUID. Timestamp is one of two errors in the field (based on the used bond statement). If bound in this way: cass_statement_bind_int64_by_name (pStmt1, "date", timestamp); I get the following error: Inva...
