I am using Office Web components to fill an Excel template with values. The template is in Excel xml format, containing all relevant fields and layout options including the page layout, landscape in this case. I'm filling this template with some real fields using the code below.
Set objSpreadsheet = Server.CreateObject("OWC11.Spreadsheet")
objSpreadsheet.XMLURL = Server.MapPath("xml") & "\MR1_Template.xls"
'Fill cells with values here
Response.ContentType = "application/vnd.ms-excel"
Response.AddHeader "Content-Disposition", "inline; filename=" & strFileNaam
Response.write objSpreadsheet.xmlData
After the new Excel file has been saved, the page layout options are gone. I've looked at the API documentation for the OWC but cannot find the option to specify the landscape page-layout
I'm not sure if you are passing in the right data. XMLURL seems like an odd method name to be passing in a XSL template into?
If all you are doing it doing a xsl transformation then why not just use DOMXmlDocument similar to this article:
http://www.codeproject.com/KB/XML/xml_spreadsheet_to_csv.aspx
Cut and paste for ease:
Dim xslt As New XslTransform
'Load the stylesheet.
xslt.Load(Server.MapPath(".") & "excel2csv.xsl")
Dim doc As New XmlDocument
'xmldata is string, use doc.Load(fileName) for file.
doc.LoadXml(xmlData)
'Create an XmlTextWriter which outputs to a file.
Dim fileName As String
fileName = Server.MapPath(".") & "book.csv"
Dim writer As XmlWriter = New XmlTextWriter(fileName, Nothing)
'Transform the data and send the output to the console.
xslt.Transform(doc, Nothing, writer, Nothing)
writer.Close()
After some detailed comparison of the template excel sheet (as xml) and the resulting xmlData I've decided to hack the page layout in the resulting Xml. These are the options I've added:
<x:WorksheetOptions>
<x:PageSetup><x:Layout x:Orientation="Landscape"/></x:PageSetup>
<x:FitToPage/>
<x:Print>
<x:FitWidth>2</x:FitWidth>
<x:ValidPrinterInfo/>
<x:PaperSizeIndex>9</x:PaperSizeIndex>
<x:Scale>87</x:Scale>
</x:Print>
</x:WorksheetOptions>

I am currently working on a project that will import data from multiple different sources in a variety of formats and structures - e.g., CSV, fixed-length, other-delimited (tab, pipe, etc.) plain-text, and Excel worksheets/workbooks. For this, I'm attempting to build "generic" readers for these files which will throw the files' contents into a DataTable/DataSet I can use in other methods. The plain-text files are pretty simple as I've created a large SCHEMA.INI file which contains field definitions for each of the files the system will handle. That SCHEMA.INI resides in a "processing folder" where the files are temporarily stored until their data has been integrated with other systems. A defined text files' data can be easily extracted using this method:
Private Function TextFileToDataTable(ByVal TextFile As IO.FileInfo) As DataTable
Dim TextFileData As New DataTable("TextFileData")
Using TapeFileConnect As New OleDb.OleDbConnection("Provider=Microsoft.Jet.OleDb.4.0;Data Source='" + TextFile.DirectoryName + "';Extended Properties='Text';")
Using TapeAdapter As New OleDb.OleDbDataAdapter(String.Format("SELECT * FROM {0};", TextFile.Name), TapeFileConnect)
Try
TapeAdapter.Fill(TextFileData)
Catch ex As Exception
TextFileData = Nothing
End Try
End Using
End Using
Return TextFileData
End Function
This works well because a plain-text file isn't terribly complex in its data structure. A single file generally (at least for my requirements) contains, at most, one single table's worth of data - unless, of course, it's some sort of complex XML or JSON structure file, which can/should be handled completely differently anyway - so there's no need to go iterating through different elements beyond this.
NOTE: The code above is dependent on the SCHEMA.INI file being present in the same directory as the plain-text file being read and there being a section within that SCHEMA.INI defined with the same name as that plain-text file.
EXAMPLE:
[EXAMPLE_TEXT_FILE.TXT]
CharacterSet=ANSI
Format=FixedLength
ColNameHeader=FALSE
DateTimeFormat="YYYYMMDD"
COL1=CUSTOMER_NUMBER TEXT WIDTH 20
COL2=CUSTOMER_FIRSTNAME TEXT WIDTH 30
COL3=CUSTOMER_LASTNAME TEXT WIDTH 40
COL4=CUSTOMER_ADDR1 TEXT WIDTH 40
COL5=CUSTOMER_ADDR2 TEXT WIDTH 40
COL6=CUSTOMER_ADDR3 TEXT WIDTH 40
...
Excel workbooks, however, can be a bit trickier. Several of the workbooks I have to process contain multiple worksheets worth of data that I want to consolidate into a single DataSet with a DataTable for each worksheet. The basic functionality is, again, fairly straightforward and I've come up with the following method to read any and all sheets into a DataSet:
Private Function ExcelFileToDataSet(ByVal ExcelFile As IO.FileInfo, ByVal HasHeaderRow As Boolean) As DataSet
Dim ExcelFileData As New DataSet("ExcelFileData")
Dim ExcelConnectionString As String = String.Empty
Dim UseHeaders As String = "NO"
Select Case ExcelFile.Extension.ToUpper.Trim
Case ".XLS"
ExcelConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source={0};Extended Properties='Excel 8.0;HDR={1}'"
Case ".XLSX"
ExcelConnectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source={0};Extended Properties='Excel 8.0;HDR={1}'"
End Select
If HasHeaderRow Then
UseHeaders = "YES"
End If
ExcelConnectionString = String.Format(ExcelConnectionString, ExcelFile.FullName, UseHeaders)
Try
Using ExcelConnection As New OleDb.OleDbConnection(ExcelConnectionString)
Dim ExcelSchema As New DataTable
ExcelConnection.Open()
ExcelSchema = ExcelConnection.GetOleDbSchemaTable(OleDb.OleDbSchemaGuid.Tables, Nothing)
For Each ExcelSheet As DataRow In ExcelSchema.Rows
Dim SheetTable As New DataTable
Using ExcelAdapter As New OleDb.OleDbDataAdapter
Dim SheetName As String = ExcelSheet("TABLE_NAME").ToString
Dim ExcelCommand As New OleDb.OleDbCommand
SheetTable.TableName = SheetName.Substring(0, SheetName.Length - 1)
ExcelCommand.Connection = ExcelConnection
ExcelCommand.CommandText = String.Format("SELECT * FROM [{0}]", SheetName)
ExcelAdapter.SelectCommand = ExcelCommand
ExcelAdapter.Fill(SheetTable)
End Using
ExcelFileData.Tables.Add(SheetTable)
Next ExcelSheet
End Using
Catch ex As Exception
ExcelFileData = Nothing
End Try
Return ExcelFileData
End Function
The above code will work in a majority of the cases I deal with, but my "difficulty" is that there may be some worksheets that have header rows and some that don't within the same workbook. Also, for those worksheets that do not have a header row, I'd like to be able to define the field names and data types similar to how I can with the plain-text SCHEMA.INI. The only thing I have going for me in these cases is that the "client" provides me with a data map to help me identify what data elements are in each field.
What I'd like to know is if there is a way similar to the text file's SCHEMA.INI to define the structure of an Excel workbook and the worksheet(s) it contains - including column data types to avoid the OleDb driver from "misinterpreting" a column's data - ahead of time. I imagine this could be any sort of structured file such as INI, XML, or whatever, but it would need to be capable of identifying whether or not a particular sheet contains a header row or, in lieu of such a row, the (expected) column definitions. Does any such "standard definition" file exist for Excel workbooks?
One thing to note: As you may have noticed in the code for the ExcelFileToDataSet() method, I may be dealing with the older .XLS (97-03) format or the .XLSX (07+) format, so I can't necessarily rely on the workbook being Open XML compliant. I suppose I could try breaking the methods out to one for each extension, but I'd rather find something that I can use regardless of which file format the Excel file is using.
Been using this code for a while to upload a file to SharePoint and noticed the other day that when the file is uploaded, it is checked out to myself automatically and have to go into SharePoint and manually check-in so that others can view the file. Any way to modify or add to my code below to auto check-in a file after it uploads? Totally stumped and any help would be greatly appreciated.
Sub SharePointUpload()
Dim WSN
Dim spAdd
Set WSN = CreateObject("WScript.Network")
spAdd = "https://mysharepoint/test"
WSN.mapnetworkdrive "N:", spAdd
ActiveWorkbook.Save
Dim SharepointAddress As String
Dim LocalAddress As String
Dim objNet As Object
Dim FS As Object
' Where you will enter Sharepoint location path
SharepointAddress = "\\mysharepoint\test"
' Where you will enter the local file path
LocalAddress = "C:\data\sample_file.xlsm"
Set objNet = CreateObject("WScript.Network")
Set FS = CreateObject("Scripting.FileSystemObject")
If FS.FileExists(LocalAddress) Then
FS.CopyFile LocalAddress, SharepointAddress
Else: MsgBox "File does not exist!"
End If
Set objNet = Nothing
Set FS = Nothing
WSN.removenetworkdrive "N:"
End Sub
I had the same issue with our SharePoint Document library even with option Require Check Out switched off - some documents (Word, Excel) were uploaded as Checked Out automatically (green arrow mark) whereas others were in fact Checked In from upload. Moreover when I wanted to Check In manually such documents, I got error message about missing mandatory field, although there was no field in the library set as mandatory.
The reason in my case was the field Title. This field is presented in library as default text field and it is also presented in Office files. I noticed that for Office files with empty field Title the document is automatically Checked Out during upload. When uploaded document contained some text in Title property, no Check Out was set. I also tried to use workflow to change the Title and then Check Out file (after creation), but it was not working - initial Check In was required to start the workflow. Manual change of document properties works but that's too tedious...
The first programmatic option to handle this issue could be to fill Title property of uploaded document when empty (i.e. add file name or any other text). Should work well with many languages. Example with Python:
from docx import Document
path = 'D:/myfile.docx'
document = Document(path)
document_property = document.core_properties
if not document_property.title:
document_property.title = 'Everything is Awesome'
document.save(path)
In VBA Title should accessible via Wb.BuiltinDocumentProperties("Title").
Another successful option for me was to find column Title in Columns of Document library and rename it to something else (I used Titlex as new name), then try to upload new document with empty Title - this time there was no automatic Check Out for the uploaded document. Then I could set the Titlex back to Title without returning the issue.
I have this code:
Dim xmlOBject As Object
Set xmlOBject = CreateObject("MSXML2.DOMDocument.6.0")
xmlOBject.async = False
xmlOBject.Load ("https://api.evemarketer.com/ec/marketstat?typeid=2268&typeid=2305&typeid=2267&typeid=2268®ionlimit=10000032")' just example URL
The xmlOBject variable contain the XML resulte.
Is there a way to convert a XML resulte to array, VBA only, without using the sheet to paste the XML resulte, also it should be dynamically, it means that no matter how many xml levels/nodes there are, so it will works with any given URL ?
The above URL should provide the this array(like the attached image without the titles):
I am trying to export a report to excel. When I export my report to Excel I am getting blank rows between each detail section. I assume this is because I have a context menu in form of a normal text element which overlies the "normal" text elements.
Does anybody have any advice on how I can stop the blank rows occurring? Is it possible to suppress a text element only when it is exported to Excel?
Thanks!
Try to make it compact.
It should be no space between each object. You should set every object on the same row has the same height and every object on column has the same width.
When there's a space between objects, it will create a cell on excel.
There are 2 articles from Ken Hamady that might be helpfull:
http://kenhamady.com/cru/archives/231
http://www.kenhamady.com/news0506.shtml (scroll to the bottom of the page)
Another option , if you are working with tabular data is to use a report extension like it is shown in this video: https://www.youtube.com/watch?v=3hk6FJ1dvb4
This approach will use the Crystal report as a datasource and will export the data from a grid with much better formatting. The video is using a 3rd party tool, but it is free - http://www.r-tag.com/Pages/CommunityEdition.aspx
Use This Code:
Public Shared Sub ExportDataSetToExcel(ByVal ds As DataTable, ByVal filename As String)
Dim response As HttpResponse = HttpContext.Current.Response
response.Clear()
response.Buffer = True
response.Charset = ""
response.ContentType = "application/vnd.ms-excel"
Using sw As New StringWriter()
Using htw As New HtmlTextWriter(sw)
Dim dg As New DataGrid()
dg.DataSource = ds
dg.DataBind()
dg.RenderControl(htw)
response.Charset = "UTF-8"
response.ContentEncoding = System.Text.Encoding.UTF8
response.BinaryWrite(System.Text.Encoding.UTF8.GetPreamble())
response.Output.Write(sw.ToString())
response.[End]()
End Using
End Using
End Sub
Finally I've solved this issue, after a long time researching. Make the fields inside the details section fill the whole height of the section... no spaces between fields and top and bottom edges.
instead of this
I'm reading an XLSX (Microsoft Excel XML file) using the Excel Data Reader from http://exceldatareader.codeplex.com/ and am having a problem with missing data. Data which is in the source Excel spreadsheet is missing from the data set returned by the library.
Here's a bit more detail of what I'm doing:
Created a simple test spreadsheet in Excel with one sheet, a header row and two data rows. Save and close Excel.
Open the file and pass the stream into the CreateOpenXmlReader() method and get back an IExcelDataReader.
Call the AsDataSet() method on the IExcelDataReader and get back a DataSet.
Get the ItemArray from row 1 of table 0.
Loop through the ItemArray. Discovered there is data missing (i.e. there are System.DBNull members where I expected System.string members).
Here's a bit more analysis...
I debugged the code and looked inside the ExcelDataReader object model. Found a non-public string array called "SST" which appears to contain the data from the spreadsheet as a single linear (one-dimensional) array.
On closer inspection, I found that the data I was looking for was also missing from this array. In this raw data, the member does not exist at all.
My guess is that for some reason the parser is not picking up the data from the OOXML and concluding that the cell is empty. Looking at the OOXML itself, the data seems to be split across the sharedStrings.xml and sheet1.xml files, so perhaps the parser is having a tough time putting all this together.
Saving the file in binary format (Excel 97 to 2003) and reading that in solves the problem so on the surface that seems to confirm my suspicion is with reading the OOXML format.
Suggestions?
As a stop gap I'm converting all files to binary format, but that seems like a kludge. Is there some way to get my OOXML formatted Excel files to read in properly with Excel Data Reader?
To retrieve an Excel spreadsheet (.xlsx) and load it into a DataSet, you don't need to mess with XML readers or a separate library like Excel Data Reader. The code for reading an entire spreadsheet into a DataSet is pretty simple when using the normal OleDb functions in .NET:
Sub readInMyExcelFile
Dim xlsFile as string = "myexcelfile"
Dim conStr As String = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" & xlsFile & ";Extended Properties=""Excel 12.0 Xml;HDR=YES"""
Dim dtSheets As New DataTable
Dim tmp As String
Dim sqlText as Sting
Using cn As New OleDbConnection(conStr)
cn.Open()
dtSheets = cn.GetSchema("Tables")
End Using
//Dataset for the spreadsheet
Dim ds as New DataSet
/Loop through the names of all the worksheets in the file.
For Each rw as DataRow in dtSheets.Rows
tmp = rw("TABLE_NAME")
tmp = "[" & tmp & "]"
Dim dt as New DataTable
Using cn as New OleDbConnection(conStr)
cn.Open
/Retrieve all the records from the worksheet.
sqlText = "SELECT * FROM " & tblName
Dim adp As New OleDbDataAdapter(sqlText, cn)
/Fill the data table with the all the data.
adp.Fill(dt)
End Using
ds.Tables.Add(dt)
Next
End Sub
It seems there is a bug in Excel Data Reader (it is first time I have heard about it). Do you have to use it? If not, EPPlus would be a better choice.
excel datareader from codeplex is used for reading data from the excel file directly on web application without any sort of caching on the server.the above code only stands when we can store the excel file somewhere.I have faced similar problems with exceldatareader where some of the data are missing.Most importanly i coludnt find any specific trend.All i cud see that if all the rows have values then there is no problem. Best chance is to convert xlsx to xls.
