Recently i got this task to create a custom Chart control WebPart in SharePoint. The task basically was to plot a graph using some data table values. X & Y axis were based on the columns of the data table. As the Chart type used was a Range Bar, the X & Y axes were reversed.

Basic Data Binding

To bind a chart control with a data table, “DataBindCrossTable” method is used. The below code plots a graph based on the data table values.


Code
Problem with Basic Data Binding

However, there is one big issue when using the above code - Since the column values in the data table ( that maps with X axis) are not unique, X axis labels are also not unique. This means that the maximum value of X axis will be the last row value for the mapped column.


Solution

After spending few days searching for a fix, i found that using “Custom Labels” and manipulating "DataPoints" can resolve this issue.

When creating a Virtual Machine, some amount of storage is allocated to it. It can be either dynamic or fixed. Over the course of time, as we add more files and additional software installs to the VM, the free space inside the VM starts to decrease. To resolve this, we need to increase the free space by re-sizing the VM disk. 

Note - 
  • Super Imp - Kindly backup the VM image before re-sizing, in case a rollback is needed.
  • The steps mentioned below are for a VM (with dynamic storage ) created using Oracle Virtual Box. 

To increase the size of a Virtualbox VM with dynamic storage -

  1. Open command prompt as admin.
  2. Change dir to C:\program files\Oracle\VirtualBox.
  3. Type vboxmanage.exe modifyhd “<Full VM path>” -–resize <Size in MB> and click enter. The resizing process will start.
  4. Once resize is completed, verify the storage space in Virtualbox interface.
  5. Start the VM and open Computer Management and Goto Disk Management. You will see the increase space as unallocated. 
  6. Right click on the drive for which the size has to be increased. Click on Extend Volume and add the allocated space and click OK.
  7. Once done, the additional space will be reflected instantly.

Enable JavaScript in the latest version of Firefox



Last week, while browsing, i ran into one issue- I was unable to load any popup on Firefox browser. Case in point- when trying the sign in for “Digg Reader”, the browser was not opening the sign in window.  I tried restarting the browser, but that also didn't work.

Now since this was related to popups, i figured it must an issue with browser JavaScript option.

But in the latest version, there is no such setting in “Options” menu. After digging through some forums, i found the below solution-  

1. Type about:config in the browser address bar and click “I’ll be careful. I promise” button.

2. Search for javascript in the search box. This will show all javascript related options.

3. Right click the result named “javascript:disabled” and click toggle. This will change the settings to “javascript:enabled”.

4. Reload the tab to see the popups.

A part of our professional life is occupied by Meetings and Conferences. Managing MoMs, tracking assigned tasks, exchanging notes and etc can be very time consuming at times. This may not only lead to messy and redundant documents, but also reduce one’s efficiency.


Google Docs provide an excellent way to efficiently create and manage meeting notes. For one, all documents will be stored on Cloud, so its easily accessible; Secondly, its allows sharing and simultaneous editing of these docs. Offline capability is also provided for Google Docs.


Once our meeting documents are created, we can use GAS to automate certain tasks. One of these tasks is to send MoM documents. To automate this task, I have created a small script that sends an email once a meeting document is freezed (Starred).


Prerequisites -


The script will do the following -
  • Find the required folder where all meeting related documents are stored.
  • Collect all GDocs that has last modified property as today and are starred as well.
  • Email these docs as PDF attachments along with doc URL to the required team members. This is done by using “Time-Driven Triggers” in GAS.


Note : This script doesn’t code doesn’t include exception handling.

This is just one example. We can use the power of GDrive and GAS to manage and automate myriad tasks.
