hi,

sorry, i mean Structure of Excel Sheet create by ADO

it did accept DATETIME in Structure for a Excel Sheet, but when XBROWSE / EDIT it fail
i have to change back to DATE to make it work again

Posted: **Sun Aug 13, 2023 10:26 am**

This is the program I tested just now.

Code: Select all | Expand

function TestXl()

   local oCn, cSql, oRs, oRec

   oCn   := FW_OpenAdoExcelBook( TrueName( "some.xlsx" ) )
   TRY
      oCn:Execute( "DROP TABLE [TESTDT]" )
   CATCH
   END

TEXT INTO cSql
CREATE TABLE [testdt] (
 [NAME]     VARCHAR(20),
 [JGDATE]   DATE,
 [TSTAMP]   DATETIME
 )
ENDTEXT

   oCn:Execute( cSql )
   oRs   :=  FW_OpenRecordSet( oCn, "select * from [testdt]" )
   oRs:AddNew( { "NAME", "JGDATE", "TSTAMP" }, { "Albert", Date() - 400, HB_DateTime() } )
   oRs:MoveFirst()
   oRec  := TDataRow():New( oRs )
   oRec:Edit()
   oRs:Close()
   oCn:Close()

return nil

DateTime works

hi,

thx for Answer and Sample

a.) i got Error that "some.xlsx" does not exist when use FW_OpenAdoExcelBook()
i have use another *.XLSx and rename it to "some.xlsx"

b.) now i got into edit and press "new" an begin to "fill" it
when press "save" it "jump" to DATE FIELD where i input 01/01/01

c.) there is no "[testdt]" (or testdt*.*) create

---

i close Sample and want to open "some.xlsx" with Excel but it fail with Error

i use my "ADO Reader" and open "some.xlsx" but it is my "old XLSx" which i have rename

Some points:
1. I prefer adopting the sql approach than using ADOX.
2. We need to be aware of the limitations of creating Excel sheets using ADO.
a) Whatever length we specify, all character columns are VarChar(255)
b) Whatever numeric datatype, like int, numeric(w,d), etc we specify the columns are finally double only.
c) Date fields accept both dates and datetime values.
d) Use field type "TEXT" for memo fields.

To have better control of column formatting we need to create Excel Sheets using Excel OLE.
ADO has these limitations.

We are going to make some necessary changes in xbrowse and other functions to accommodate the specific issues relating to Excel ADO Tables.

This is an enhanced version.
There is an option to use ADOX of SQL to create the table.
Both options work alike.
Also used datecheck necessary for MS products.

Yes.
We need an existing valid XLSX file to start with.
Obviously because ADODB connection can be connected to an existing valid xlsx file, can not connect to "nothing".

A few suggestions:

1) Instead of your CopyToClipBoard() fuction, we recommend using

Code: Select all | Expand

FW_CopyToClipboard( data, [nFormat] ) --> lSuccess

nFormat can be omitted and is mostly guessed correctly by the function.

2) Sec2HMS:
There are built-in functions in (x)Harbour already for many years.
I see no point in writing and maintaining our own code.
We can use:

Code: Select all | Expand

SecToTime( nSecs, [lMilliSecs = .f.] ) --> "hh:mm:ss[.ddd]"

Mr. Karinha

Do you know where can we get the famous TExcel class?

sorry i´m still a Newbie and do not know what Fivewin already have or can do

so i often use my old Xbase++ CODE which also work under harbour
