Formatting a spreadsheet file through smalltalk
|
|
| Suresh Kumar 2005-05-09, 3:58 am |
| Hi All,
We have created a spreadsheet file(compatible with open office and ms
office) using a Smalltalk application.
We would like to change the font and the color of the text, i.e. we have to
write in to the file in a specified format.
How can we do so from the Smalltalk application[VW7.3].
Thanks in Advance,

This is pretty independent of Smalltalk.
You did not specify in what format your spreadsheet file is written. If
it's CSV, then as far as I know you can't specify things such as font or
text color. If it's another format, you would need to check how this
format specifies these attributes.
Cheers,
Hans-Martin

If anyone knows of api for talking to .xls files I'm very interested
also.
I have found some references to using ODBC to get data from them.

| Same here. If your company allows it, this sounds like a great open
source contribution.

There needs to be better API's for OpenOffice to do this sort of thing.. And
then there needs to be better bindings from Smalltalk to C++ to tie into it.
Either way, I'm sure you can hack up OpenOffice a bit to get the job done,
but it might not be pretty or easy.

| I tried looking into that. I wanted to create a filter to convert .xls
files to tab separated files. The API wasn't inspiring.

| I'm not familiar with Open Office but to access the Microsoft Office
products such as
Word, Excel, Outlook, etc. I'd recommend using the OLE (Object Linking and
Embedding)
interface. Using a custom built OLE wrapper class, I was able to build and
manipulate
Excel spreadsheets, call Word spellcheck, lookup Outlook addresses, etc. for
the programs
written for my commercial clients.
Caveat: I wrote these under VisualAge Smalltalk versions 4.02-6.01 using
IBM's OLE
Automation Object class. I also put a sample MS Word Spell Check example on
D. Pennington's Totally Object Web site:
http://www.totallyobjects.com/vafree.htm
I'm not an expert with VisualWorks, but it appears you could use the
DLLConnect
feature to build a similar OLE Automation class and call the MS OLE DLLs.
I've called
MS DLLs numerous times under VisualAge Smalltalk and it was straight
forward,
especially if you've used MS Visual Studio.
An alternative is to ask a vendor if they would consider developing a
wrapper class
for commerical resale...

This may be viable.
Thanks for the info on OLE.

| I would very like to have a connection to OpenOffice, but the
whole stuff is much more difficult than working with MSWord
or MSExcel.
They go more and more with Java and though OpenOffice is platform
independent they have "strange" unusual interfaces - and they
produce documentation over documentation and most of it is not
really helpful - I think having a Smalltalk browser on top of
OpenOffice would help them much much more.
In general we wrote StarBasic libraries, which we call from our
VA Smalltalk systems - but even here StarBasic is pretty bad
compared against VBA.
I think if one want to start with this stuff, they should have
a look at the Python connection ... pretty much the same should
be possible with Smalltalk - and the Python programmer mentioned,
that all untyped languages are better suited for a wrapper than
typed languages.

| Suresh,
There are examples for manipulating Excel files in the COM Interface
code that ships with VW. I've used this from VW 7.x on Windows to
populate and format Excel files in the past.

| In Squeak 3.7 i have seen an OpenOffice-Importer. Maybe you can port it
to VW and use it.
