Let’s go back to the key point here. To add the jdbc jar to NetBeans IDE, you just need to right click the Libraries node and choose Add JARFolder…

    + “Data Source=” + strFilePath + “;”

    + “Extended Properties=’Excel 8.0;HDR=No'”;

    OleDbConnection connExcel = new OleDbConnection(strExcelConn);

    OleDbCommand cmdExcel = new OleDbCommand();

        //Check if the Sheet Exists


        DataTable dtExcelSchema;

        //Get the Schema of the WorkBook

Task Manager vs Process Explorer

This is a short article that let you know there is alternative to Task Manager.

One day my colleague has told me his laptop has been taking long time to start. So the Process Explorer cross my mind.  

The obvious comparison below between the Properties in Task Manager and the Properties in Process Explorer for the same process (PID 7000).


You may not find some of the below Process Explorer features in Task Manager.

·        The default tree view shows the hierarchical parent relationship between processes, and displays using colors to easily understand processes at a glance.

·        Very accurate CPU usage tracking for processes.

·        Can be used to replace Task Manager, which is especially useful on XP, Vista, and Windows 7.

·        Can add multiple tray icons to monitor CPU, Disk, GPU, Network, and more.

·        Figure out which process has loaded a DLL file.

·        Figure out which process is running an open window.

·        Figure out which process has a file or folder open and locked.

·        View complete data about any process, including threads, memory usage, handles, objects, and pretty much anything else there is to know.

·        Can Kill an entire process tree, including any processes started by the one you choose to kill.

·        Can Suspend a process, freezing all its threads so they do nothing.

·        Can see which thread in a process is actually maxing out the CPU.

·        The latest version (v16) integrates VirusTotal into the interface so you can check a process for viruses without leaving Process Explorer.  

To download Process Explorer go here:
