Microsoft Office 365 seems to be now available to Monash University students

Monash University is a solid Google Apps user, for both students and staff. In March 2015, Microsoft Office 365 is now available too, but only to students.

Microsoft Office 365 is Office cloud webapps, installable classic Office 2013 desktop programs and OneDrive cloud storage. The sign on is:

A. Go to the Office 365 explanation page. You then click the link to go to the Office 365 sign in page as illustrated in 1.

B. That sign in page detects the user's email address and does not wait to capture the authcate password and redirects you to the Monash Uni specific sign in

C. The student then gets to the screen where the desktop apps are offered.

You know how Access 2013 won't open the Northwind 2000 .mdb file?

You know how Microsoft Access has been engineered to lack the ability to open Access .mdb files? Brain dead idea by the team. Even if they want to deprecate .mdb files and move onward, you want to be able to open or transfer legacy files from wherever or whomever you got them. That's your  user owned and invested data, not some arbitrary decision to be made by the database vendor. Now, if your organisation has moved on to Office 2013 and abandoned Office 2010, you will have to beg, steal or borrow a machine that can open and convert .mdb files.

It's a really silly situation. Because nobody told the Visual Studio 2013 / .NET framework 4.51 team to abandon this Access '97 .mdb file format as a data source.

Visualising Data

It's really hard to visualise data on-the-spot when it's not data that I live with.

Happy 50th Birthday, BASIC

I work almost daily with Microsoft Visual Basic for Applications - the language built into Microsoft Access, Excel, Word, Powerpoint, Project. It could stand improvements in elegance and modernity - that's what Visual Basic.NET was supposed to be. Except that Microsoft Office is written in COM architecture, not .NET - so VB.NET doesn't look like it's going to be embedded into Office-as-we-know-it.

But that's an aside. VBA itself is a descendant of the Microsoft's earliest BASIC, which was patterned after Dartmouth BASIC

Getting database data from Microsoft Excel

A friend asked me whether Excel could reach out to SQL Server data and grab data. I haven’t checked out this facility for a long time, so whipped up Excel 2013 and gave it a whirl.

Firstly, in Excel 2007, 2010 and 2013 the external data commands have been consolidated into the External Data tab of the Excel Ribbon. That’s good and easy to find.

Secondly, Microsoft Query is still alive and well for ODBC and local database connections. Except that no cosmetic work has been done on it – it looks really ugly on Windows 8 and the File Open / Save dialogs are even older, circa Windows 3.1 Despite this, it is still the nexus that connects Excel to these data sources.

Thirdly, with the new generation Excels, data grabbed from databases is dumped into Excel Tables – which is good – one of the excellent features in new generation Excel versions is the Excel Table.

Excel External Data Sources

As you can see, Excel continues to expand it’s ability to retrieve data from many kinds of data sources.

For this discussion, we are interested in classic tabular data sources – Microsoft Access database, SQL Server database, ODBC databases.

Notice Microsoft Query is an option. This will launch Microsoft Query.

Workbook Connection and data in Excel cells

After you have defined your request, you will be able to save a separate .dqry file or embed the request directly into the current Excel file. Your Excel file will have a Workbook Connection

Defining your Microsoft Query request

Microsoft Query has a simple user interface to

  • choose which database table or view/query
  • choose which columns you want
  • state your criteria to filter the data (parameterised stored procedures are not supported)
  • choose the sort order

You can use wizard driven screens or non modal user interface – the user interface crudely looks like Microsoft Access’s Query Design screen

Wizard dialogs

Microsoft Query Design Screen

More Advanced Data Retrieval

If you need to perform more complex data retrievals and coupling with parameter driven server-side Stored Procedures / Queries, you can use the VBA language in combination with Data Access Objects or ActiveX Data Objects to establish the request programmatically and form a Recordset which can then place the data into Excel cells. See KB 185125

Making formulae easier to follow in Excel

In the old days, we would write really long formulae with nested functions. Pre Excel 5.0 and in other products, we did not have the niceties of VBA as a supplementary classic programming language so we used to torture ourselves.

Fast forward to 2013 and Excel generations 2007 and later have niceties in display and useage that reduce the pain of long formulae. Courtesy of +Bill Jelen’s discussions on social media, we know that we can use:
  • you can use spaces in the formula. Instead of typing A1+A2, you can type A1 + A2 chunking out the formula and improving readability. You can’t put a leading space before the first = sign. You can’t put a space between the function name and the bracket e.g. SUM( is ok, SUM ( is not
  • you can use Alt+Enter to insert line breaks in the formula bar. Remember that in Excel 2007 onwards, you can pull down the floor of the formula bar, increasing the number of lines Excel will display. This allows more classic programming language display.
  • you can use the Name Box when you build the formula in the Function Builder. We know that. However, did you know that you can use the Function Builder repeatedly in a formula with nested functions?

Screen Capture in the Windows 8

There are several options to screen capture classic desktop (programs):

  • PrtScr to save to clipboard
  • the Windows Snipping Tool
  • Microsoft Office 2010 (and later) programs have an Ribbon Command – Insert > Screen Shot > Screen Clipping
  • Greenshot – a very nifty free utility that can capture, save to file automatically, upload to various photo gallery sites automatically
  • the Windows Problem Steps Recorder (records a screenshot every keystroke sequence or mouse action you carry out until you stop.
  • and a host of third party free and paid utilities

However, the Windows 8 Apps Tiles Layer breaks your workflow – If you use one of the utilities above, after the screenshot, Windows returns to the classic Desktop. If you return to the Tiles layer, some Tile Apps lose state.

Use Windows logo key + PrtScr and the screenshot will save to My Pictures/Screenshots as a PNG file automatically, without switching to the Classic Desktop.

Free Intro to VBA Excel

I often look for reference material for people intending to pick up Visual Basic for Applications (VBA) and program Microsoft Excel. Just today, encountered this compilation by Hooman Askari-Nasab
