Question

Access Excel

Asked by: olevb1

I have an access database which contains 3 fields:

     Field Name       Datatype
1)      Id     as     Text
2)      Obj    as     OleObject
3)      Pic    as     Longbinarydata ( to       store .gif/.bitmap )

Now, i want to populate this data in excel spreadsheet.
I tried many options, i could retrieve the text field but the other fields, i could not.
In a crude way i managed to retrieve the data by first copying the object to the clipboard and the pasting it on the excel (ofcourse using 2 seperate programs--VB/Access was one program to copy the object to the clip board & to paste back was VBA / EXcel).
What I want is the entire process of populating the access database should be done by VBA.

I would be glad if any alternate procedure is suggested, but the procedure should be programmable (done through a code)

olevb1,

You mention that you succeeded in copying the ole object field to the clipboard using VB/VBA.

If you can show how you did that, I can surely help you to finalize this, all the rest is known to me.

 

by: calacucciaPosted on 2001-12-28 at 09:35:00ID: 6698978

Olevb1,

Please try the following code, which of course, needs some adaptation to your own DB names. Also, it requires that you create a form ("EETest" in the macro), which shows all the objects for each record.

You also need to set a reference to the 'Microsoft Excel 8.0 Object Library' in your protect (Tools/references) - (might be 9.0 boject library, if using Office/Excel 2000)

Good Luck

Following function will export any SQL statement supplied to it to an Excel spreadsheet.  Also, with this code no reference has to be made to Excel 8.0 for it to function.

Public Function Export_SQL_To_Spreadsheet(strSQL As String)

On Error GoTo ErrorHandler

Dim dbs As Database, rst As Recordset

Set dbs = CurrentDb
Set rst = dbs.OpenRecordset(strSQL)
If rst.EOF Then

Maathias,

Your code indeed bears some advantages, but the real issue here is the exporting of the OLE Data Fields to Excel, which is absolutely not handled by Excel cells in a normal way, that's why I am working with the at first sight complicated copy to and paste from Clipboard, and also using a form with the OLE Data field contents to be able to copy something.

 

by: maatthiasPosted on 2001-12-28 at 16:25:06ID: 6699719

Indeed, you're right.  My code would not handle OLE objects.

olevb1,

You mailed me this

"Well i could come out of the database type problem:
The pb is i m mot able to understand what does your
following statement says:
requires that you create a form ("EETest" in the
macro), which shows all the objects for each record

What is expected to do here.

And now i m facing this pb:
Set mRecSet = mTbl.OpenRecordset("Select * From
PicTable")  --> gives type mismatch error-- i m not
able 2 sort this out

Reply Soon,
Bye"

I would prefer if you ask updates in the frame of this question.

Anyhow,

the form you need to make is an Access form which shows the three fields for the export you are trying to do to Excel. I need the form to show these fields for each record, to be able to copy them to the clipboard, and paste them into Excel. The name you choose for the form and the name of both OLE controls is indicated in these two lines

Set mControl1 = Forms("TestEE").Controls("Obj")
Set mControl2 = Forms("TestEE").Controls("Pic")


The Type mismatch message is probably because you have both DAO en ADO references set in Tools/References for your project as this article explains:
http://support.microsoft.com/default.aspx?scid=kb;EN-US;q181542

You can overcome it by doing this in the declaration section

Dim mTbl As Database, mRecSet As DAO.Recordset
