How would u answer - what have u done in OOP?

IceBikers — Tue, 15 Sep 2009 10:28:52 +0800

Hi fellow software developers,

I would like to ask whether you have been thrown a queston like below,

"what have you done in OOP" (Object Oriented Programming)

I'm doing vb.net, more than 70% of my works are in UI and I'm more likely a street smart person (aint smart also lol)

I couldn't figure out how would and should I answer this question??

I'm asking this because i saw it from a job vacancy that we need to tell how much we know.

p/s: is there any site can test OOP skill level??

datatable to datagridview

IceBikers — Sat, 17 Jan 2009 08:51:41 +0800

Hello, i would like to get you guys idea about ploting live data from datatable to datagridview.

let me explain to u the process to retriving data from the source:
raw data -> filter process -> put into datatable -> present at datagridview

this raw data comes every seconds.

no database involve at all.

method i have tried are:

i)
dgv.datasource = dataset.table();
this method is fast, but the UI control is not independent , as every new data come in the datagridview will be re-initiate which is not a good solution

ii)
datagridview virtue mode (currently using)
by this method, i able to control my ui and data separately. but the ugly thing when u scroll down u will notice the change of data(e.g set datacell color) very obvious n lag.

lag as in it need to keep on retrieve data when it is needed by the cell.

iii)

any idea of the third, fourth n ect how to plot data to datagridview effectively?

merge datatable and remove row

IceBikers — Sun, 23 Nov 2008 22:01:30 +0800

Hi.. i have 2 datatable..

dtFinal and dtTemp

dtFinal is use with datagridview with virtualmode where dgv get data from cellvalueneeded event.

dtTemp is use to pull http data every interval second.

once http data is pulled n it will put into dtTemp then i use dtFinal.merge(dtTemp).

yes updated data does merged and updated but how to remove rows that no longer exist?

for example:
currently dtFinal has 5 rows
11|111
22|222
33|333
44|444
55|555

then dtTemp has updated data with 7 rows
11|111
33|333
66|666
55|555
77|777
88|888
99|999

then dtFinal would be
11|111
22|222
33|333
44|444
55|555
66|666
77|777
88|888
99|999

how to remove the rows that no longer exist automatically?
