Excel automation

[cj]

I want to start a workbook and add sheets to it one at a time.

Right now my code opens a workbook and it has 3 sheets alread in it and
I don't even know how to move from one to another. Any help would be
appreciated. Here is my code.

Dim oXL As Excel.Application
Dim oWB As Excel.Workbook
Dim oSheet As Excel.Worksheet

oXL = CreateObject("Excel.Application")
oXL.Visible = True

oWB = oXL.Workbooks.Add

I would check out the microsoft.public.excel.programming newsgroup.
It's almost all vb6 and excel vba, but you can easily convert the
samples to .NET syntax. As far as selecting a sheet in excel, i believe
it goes something like this: (be warned I don't have excel on this PC,
I'll check back tomorrow at work to see if I typed something wrong)

oXL.ActiveWorkbook.Sheets("Sheet1").Select

If the excel programming news group doesn't deal with a specific .NET
question please post back and I'll try to help you out.

Thanks,

Seth Rowe

Hi

We can use the Automation code as below to delete the another two sheets.
Imports Excel = Microsoft.Office.Interop.Excel
Module Module1
Sub Main()
Dim oXL As Excel.Application
Dim oWB As Excel.Workbook
Dim oSheet As Excel.Worksheet
oXL = CreateObject("Excel.Application")
oXL.Visible = True
oWB = oXL.Workbooks.Add
Dim i As Integer = 0
For Each oSheet In oWB.Sheets
i += 1
If i = 1 Then
Continue For
Else
oSheet.Delete()
End If
Next
End Sub
End Module

You may have a try and let me know the result.
BTW: For automation Office or Excel related programming, you may also try
the newsgroup below.
microsoft.public.office.developer.automation
microsoft.public.excel.programming

Peter, Here's a question for you. I have approximately 170,000 records
to import into excel (they are in a file formatted as a printable ascii
report now). To get them into excel I see two options. What I'm doing
now is to read each line of the report and for data lines add them to
the excel sheet. When I've added 65000 rows I start adding to a new
sheet. This takes forever. Would it be faster to turn the report into
multiple 65000 record comma delimited files and then import them into
excel? Is it possible to import them automatically?

 

[rowe_newsgroups]

If you can hit the data with SQL statements you could use excel's
querytables to do a much faster import.

Thanks,

Seth Rowe

Yes, writing a CSV file and importing by hand is instantaneous in
comparison. to loading each cell from VB. Now I'd love to know how to
have VB open Excel and import from 1 to 4 files as sheets in a workbook.
I'll look into it some more tomorrow but if you can give me any
pointers I'd appreciate it.

 

[rowe_newsgroups]

You may try using the macro recorder function of excel to record the
import, then adapt that code to work with VB.Net. Unfortunately, it's
been to long since I did any excel automation for me to help much more
than that (actually I don't even have excel on this computer).
Hopefully Peter or someone else will read this thread and chip in their
knowledge.

Good Luck!

Hi,

If the 170,000 records are in a DB, we can use the ADO.NET/ADO to tranfer
it into Excel.
Here is a link for your reference.

Peter,

Thanks, for the info. The data is not in a DB. I am essentially
reading an ASCII report.

I found it took a very long time to add the data from the report cell by
cell so I changed the program to send the output to a CSV (comma
delimited) file starting a new file each time a file contains 65000
records. It ran in seconds. Then I have to open Excel and starting
with sheet one go to data/Get External Data/Import Text File and import
the first CSV file then select sheet two and following the same steps
import the second CSV file etc. I want the data from each file in
separate sheets in the same Excel workbook.

I briefly looked at your links but from what I saw they can not handle
the importing of multiple CSV files into separate sheets of the same
workbook.

Thanks,
cj

Excel itself appears to only be able to load a CSV file into a "new"
workbook. If you need to load multiple CSV files, you're better off writing
EXCEL VBA code to do this or use MS-Access.

How can you say that? I gave the exact steps you can take to import the
CSV file into an existing wookbook in the message you replied to. I
bring each CSV file into a different sheet. Excel is very able to do this.

Hi CJ,

As you said, if the Data is in the plain text file, you can import it into
Excel as it is a text file.

e.g. the code below will automation Excel to import the two csv file
test.csv and test2.csv into Sheet1 and Sheet2 for your referennce.

Imports Excel = Microsoft.Office.Interop.Excel
Module Module1

Sub Main()
Dim oXL As Excel.Application

Dim oWB As Excel.Workbook
' Start Excel and get Application object.
oXL = CreateObject("Excel.Application")
oXL.Visible = True
oWB = oXL.Workbooks.Add
Dim oWS As Excel.Worksheet = oWB.Worksheets(1)
With oWS.QueryTables.Add(Connection:="TEXT;C:\temp\test.csv",
Destination:=oXL.Range("Sheet1!A1"))
.FieldNames = True
.RowNumbers = False
.FillAdjacentFormulas = False
.PreserveFormatting = True
.RefreshOnFileOpen = False
.RefreshStyle = Excel.XlCellInsertionMode.xlInsertDeleteCells
.SavePassword = False
.SaveData = True
.AdjustColumnWidth = True
.RefreshPeriod = 0
.TextFilePromptOnRefresh = False
.TextFilePlatform = 936
.TextFileStartRow = 1
.TextFileParseType = Excel.XlTextParsingType.xlDelimited
.TextFileTextQualifier =
Excel.XlTextQualifier.xlTextQualifierDoubleQuote
.TextFileCommaDelimiter = True
.TextFileColumnDataTypes = New Object() {1, 1, 1}
.TextFileTrailingMinusNumbers = True
.Refresh(BackgroundQuery:=False)
End With
oWS = oWB.Worksheets(2)
With oWS.QueryTables.Add(Connection:="TEXT;C:\temp\test2.csv",
Destination:=oXL.Range("Sheet2!A1"))
.FieldNames = True
.RowNumbers = False
.FillAdjacentFormulas = False
.PreserveFormatting = True
.RefreshOnFileOpen = False
.RefreshStyle = Excel.XlCellInsertionMode.xlInsertDeleteCells
.SavePassword = False
.SaveData = True
.AdjustColumnWidth = True
.RefreshPeriod = 0
.TextFilePromptOnRefresh = False
.TextFilePlatform = 936
.TextFileStartRow = 1
.TextFileParseType = Excel.XlTextParsingType.xlDelimited
.TextFileTextQualifier =
Excel.XlTextQualifier.xlTextQualifierDoubleQuote
.TextFileCommaDelimiter = True
.TextFileColumnDataTypes = New Object() {1, 1, 1}
.TextFileTrailingMinusNumbers = True
.Refresh(BackgroundQuery:=False)
End With
End Sub
End Module
