    replied to What listview event fired when mouse over column header
    in C Sharp
    The only way to figure out what column header is being dropped is:

    1. Find the area occupied by the header
    Code:
            [DllImport("user32.dll")]
        extern static IntPtr SendMessage(IntPtr hwnd, int message, int wParam, int lParam);
        [DllImport("user32.dll")]
        extern static bool GetWindowRect(IntPtr hwnd, out RECT rect);

        const int LVM_GETHEADER = 4127;
    ...

      Folks:

      Thanks for your help,
      I will contact Microsoft for help and research some more.
      If I find the solution, I will post back here including some code.

      In the meantime, if you have any new idea, please do throw in.

          What listview event fired when mouse over column header

          I notice that when the mouse is over a column header of a listview control, that column header is focused (or highlighted). In this case, what event is fired ?

          The reason I ask is I have listview control with 14 columns,
          I also have labels that I want to drag-n-drop the labels over the listview column headers. When that occurs, I will change the column header text to the label text.

          I have all the codes done...

            replied to LivstView Column not aligned with ListViewItem
            in C Sharp
            My problem is what is the first cell in the row goes to the 2nd column, and the 2nd cell goes to the 3rd row, so on. So all the cells in a row shifted to the right by one column.

            I found the problem. It has something to do with the ListViewSubItem .
            There is a weird relationship b/w all ListViewSubItem objects (in a ListViewItem)an d the first ListViewSubItem .

                replied to JDBC DB2 and CLOB
                in DB2
                I run the command db2 get snapshot for locks on mydb at various stages of the process, and I can clearly see that after the update there are additional locks on the table that I update.

                My question is why the lock is not released ? I set my connection to autocommit = true when I create the connection, after the update I close the PreparedStateme nt, and issue another commit but I still have locks.

                  I notice that I did not have the "lock" problem when I insert records but only when I update records.

                    JDBC DB2 and CLOB

                    I am working on a Struts application using DB2 JDBC Type 4 Driver.
                    By default, the Java Connection is autocommit and everything works fine for me,

                    I have a table with one CLOB column (32000 bytes). After I update the column, I issue an explicit commit just to make sure. And for some reason, a "lock" is put on that record. I can not select anything from that record any more unless...

                      I did bind but bound to the wrong objects. The error message is quite ambiguous.
                      Everything is all right now.

                        I figured it out. It has something to do with the BIND process.
                        To solve the problem, deverlopers have to make sure that:

                        1. the makefile points to the right database.
                        2. correct db id/ password uses to connect to database during compilation.
                        3. in C code, the EXEC SQL CONNECT must also have the USER id USING pwd portion.

                        That will solve the mysterious -805 and 51002 code.

                                    I have a Struts application developed following the MVC method (forms, actions, beans, etc)..

                                    But when A is clicked, I want to execute a script (ksh or Perl) on the server and get the response back to my form thru the use of (Javascript AJAX) Http Request object (hence, w/o refreshing my JSP page).

                                    So far so...
