[IAD2011 video replay] Is Software Evolution really Effective? (lang IT)

robertoschiabel — Tue, 10 Jan 2012 03:46:43 +0000

Il 2° video della serie replay è necessariamente quello di una voce importante e nota ai “molti” del movimento, mi riferisco a Francesco Cirillo: Is Software Evolution really Effective?

Riassumo in breve: sul lungo termine, le cose fatte bene (= da team agile e stabili, di lunga data) dovrebbero costare(=€) meno … … … e invece no!

Secondo i dati raccolti, sembra proprio che l’aggiunta di nuove feature costì uguale oppure di più, anche in software nati e cresciuti in contesto agile.

Ottimo spunto.
La pulce nell’orecchio è entrata … sperando porti risultati con fondamento oggettivo.
Magari … passare quei dati a qualcuno pratico di statistica / probabilità … qualcosa di più esplicito potrebbe uscirne, così da chiarire/supportare una o l’altra tesi.

[IAD2011 video replay] Keynote Back to Basics (lang IT)

robertoschiabel — Fri, 06 Jan 2012 13:51:38 +0000

In questo periodo di “decoupling” ho ripreso i video dell’ultimo agile day, per rinfrescare la memoria delle sessioni già viste, e per vedere quelle mancate.
Il primo della lista non poteva essere altro che il replay del Keynote tenuto da Paolo Polce: Back to Basics: OOP and Design.

Beh … che dire: semplice, asciutto, chiaro. molto buono! … again!!! :)

10 € = the price of our private data

robertoschiabel — Fri, 23 Dec 2011 01:25:44 +0000

Lately, a mobile operator had a new offer, made this way:
-refuel your mobile account, twice, each one 10€ minimun,
and you give 10€ more

condition:
-within some weeks
-use a well know payment operator

further condition required: a payment operator valid subscription of course

the payment operator needs name,surmane,email,credit card … at least

so, these data mean 10€! :O

Excel poisoning #10: fit print area in one page

robertoschiabel — Sun, 18 Dec 2011 00:01:05 +0000

In previous posts we added a new chart to current worksheet, what if we want to print the whole area only in one page ?

myWorksheet.PageSetup.PrintArea = rangeDataAndChart.Address;
myWorksheet.PageSetup.Orientation = XlPageOrientation.xlLandscape;
myWorksheet.PageSetup.Zoom = false;

Thank you to EnricoG for zoom tip.

Excel poisoning #9: customizing chart programmatically (C#)

robertoschiabel — Sat, 17 Dec 2011 23:59:32 +0000

Customize graph color.

Here is a brief sample, part III:

IOPXLS.Series chartSeries1st = myCharts.SeriesCollection(1) as IOPXLS.Series;
chartSeries1st.Format.Fill.ForeColor.RGB = (int)XlRgbColor.rgbOrange;

This snippet change color for 1st series of data.

Excel poisoning #8: customizing chart programmatically (C#)

robertoschiabel — Sun, 11 Dec 2011 08:42:24 +0000

Want to change font size to axis’ labels?

Here is a brief sample, part II:

IOPXLS.Axis chartAxisY = myChart.Axes(XlAxisType.xlCategory) as IOPXLS.Axis;
chartAxisY.TickLabels.Font.Size = myChart.ChartTitle.Characters.Font.Size;

This snippet sets axis label foint size, same as chart title.

Excel poisoning #7: adding chart programmatically (C#)

robertoschiabel — Fri, 09 Dec 2011 23:05:23 +0000

Sometimes you collect data in very different ways, but format is every time is similar … ie a 3-columns table, a pivot table, ecc.
Same way, you need to add same pre-formatted customized chart, but adding from scratch is boring and time-expensive.

Well, you can add programmatically, via macro … or via C#

Here is a brief sample, part I:

IOPXLS.ChartObjects xlsCharts = (IOPXLS.ChartObjects)myWorkSheet.ChartObjects(Type.Missing);
IOPXLS.ChartObject myCharts = (ChartObject)xlsCharts.Add(500, 100, 500, 500);
IOPXLS.Chart myChart = myCharts.Chart;

myChart.ChartType = XlChartType.xl3DPie;
myChart.SetSourceData(myRangeData, System.Reflection.Missing.Value);

(where IOPXLS is Microsoft.Office.Interop.Excel namespace)
This snippet contains few basic steps: add a chart, set position and dimentions, type (3D pie) and data source.

All chart type are available here: XlChartType Enumeration.
