First, some context. I have an excel spreadsheet with a module that, using a piece of javascript on the site, imports data from a text file generated by a website.
Set Datasheet = Worksheets("Datasheet")
...
Set qtQtrResults = Datasheet.QueryTables _
.Add(Connection:=URL, Destination:=Datasheet.Cells(1, 1))
With qtQtrResults
.WebFormatting = xlNone
.WebSelectionType = xlSpecifiedTables
.WebTables = "1,2"
.Refresh
The URL goes to "site.com/download.jsp?Login=abc&search=123" which, when accessed in a browser, creates a text file that downloads to the browser's default download directory.
My problem is that I need to replicate this functionality in Access, importing the data from this text file into an existing table.
Can anyone offer a solution (other than use excel)?
I just tested the following and it worked for me in Access 2010:
Option Compare Database
Option Explicit
Sub DownloadCsvFromWeb()
Dim httpReq As Object, stm As Object
Set stm = CreateObject("ADODB.Stream")
stm.Type = 2 ' adTypeText
stm.Open
Set httpReq = CreateObject("MSXML2.ServerXMLHTTP")
httpReq.Open _
"GET", _
"http://www.example.com/downloads/gord/test.csv", _
False
httpReq.Send
stm.WriteText httpReq.responseText
stm.SaveToFile _
"C:\Users\Gord\Desktop\test.csv", _
2 ' adSaveCreateOverWrite
stm.Close
Set stm = Nothing
Set httpReq = Nothing
End Sub
That saves the file to disk (on my desktop, in this case). The code could then go on to use DoCmd.TransferText to import the data into an Access table.

I have a Access DB containing several different tables, each with a different structure (number & names of fields, number of rows, title).
What I would like to do is to export all these tables into txt files, with a given separator ("|"), point as decimal separator, quotes for strings.
I have browsed the internet and what I got was:
use DoCmd.TransferText acExportDelim command
save a customized export specification and apply it
I get an error messagge ("object does not exist") and I think it is related to the fact that the export specification is "sheet-specific", i.e. does not apply to tables with different fields and fieldnames.
Can you help me?
thanks!!
EDIT.
I post also the original code I run. As I said before, I am new to VBA, so I just looked for a code on the web, adapted it to my needs, and run.
Public Sub ExportDatabaseObjects()
On Error GoTo Err_ExportDatabaseObjects
Dim db As Database
Dim db As DAO.Database
Dim td As TableDef
Dim sExportLocation As String
Dim a As Long
Set db = CurrentDb()
sExportLocation = "C:\" 'Do not forget the closing back slash! ie: C:\Temp\
For a = 0 To db.TableDefs.Count - 1
If Not (db.TableDefs(a).Name Like "MSys*") Then
DoCmd.TransferText acExportDelim, "Export_specs", db.TableDefs(a).Name, sExportLocation & db.TableDefs(a).Name & ".txt", True
End If
Next a
Set db = Nothing
MsgBox "All database objects have been exported as a text file to " & sExportLocation, vbInformation
Exit_ExportDatabaseObjects:
Exit Sub
Err_ExportDatabaseObjects:
MsgBox Err.Number & " - " & Err.Description
Resume Exit_ExportDatabaseObjects
End Sub
Before running the code, I manually exported the first table saving the Export_specs to a file.
Consider a db with two tables, A and B.
When I run the code A is properly exported, then I get the following errore message "3011 - The Microsoft Access database engine could not find the object 'B#txt'. Make sure the object exists and that you spell its name and the path name correctly. If 'B#txt' is not a local object, check your network connection or contact the server administration".
So, it's kind of complex. I've created a routine that imports files using ImportExport Specs, you should be able to easily adapt to your purpose. The basic operation is to create a spec that does exactly what you want to one file. Then, export this spec using this code:
Public Function SaveSpecAsXMltoTempDirectory(sSpecName As String)
Dim oFSO As FileSystemObject
Dim oTS As TextStream
Set oFSO = New FileSystemObject
Set oTS = oFSO.CreateTextFile("C:\Temp\" & sSpecName & ".xml", True)
oTS.Write CurrentProject.ImportExportSpecifications(sSpecName).XML
oTS.Close
Set oTS = Nothing
Set oFSO = Nothing
End Function
Then open this file in Notepad and replace the file name with some placeholder (I used "FILE_PATH_AND_NAME" in this sample). Then, import back into database using this code:
Public Function SaveSpecFromXMLinTempDirectory(sSpecName As String)
Dim oFSO As FileSystemObject
Dim oTS As TextStream
Dim sSpecXML As String
Dim oSpec As ImportExportSpecification
Set oFSO = New FileSystemObject
Set oTS = oFSO.OpenTextFile("C:\Temp\" & sSpecName & ".xml", ForReading)
sSpecXML = oTS.ReadAll
For Each oSpec In CurrentProject.ImportExportSpecifications
If oSpec.Name = sSpecName Then oSpec.Delete
Next oSpec
Set oSpec = CurrentProject.ImportExportSpecifications.Add(sSpecName, sSpecXML)
Set oSpec = Nothing
oTS.Close
Set oTS = Nothing
Set oFSO = Nothing
End Function
Now you can cycle thru the files and replace the placeholder in the spec with the filename then execute it using this code:
Public Function ImportFileUsingSpecification(sSpecName As String, sFile As String) As Boolean
Dim oSpec As ImportExportSpecification
Dim sSpecXML As String
Dim bReturn As Boolean
'initialize return variable as bad until function completes
bReturn = False
'export data using saved Spec
' first make sure no temp spec left by accident
For Each oSpec In CurrentProject.ImportExportSpecifications
If oSpec.Name = "Temp" Then oSpec.Delete
Next oSpec
sSpecXML = CurrentProject.ImportExportSpecifications(sSpecName).XML
If Not Len(sSpecXML) = 0 Then
sSpecXML = Replace(sSpecXML, "FILE_PATH_AND_NAME", sFile)
'now create temp spec to use, get template text and replace file path and name
Set oSpec = CurrentProject.ImportExportSpecifications.Add("Temp", sSpecXML)
oSpec.Execute
bReturn = True
Else
MsgBox "Could not locate correct specification to import that file!", vbCritical, "NOTIFY ADMIN"
GoTo ExitImport
End If
ExitImport:
On Error Resume Next
ImportFileUsingSpecification = bReturn
Set oSpec = Nothing
Exit Function
End Function
Obviously you'll need to find the table name in the spec XML and use a placeholder on it as well. Let me know if you can't get it to work and i'll update for export.
Hey i am new to access database.
I am creating a form in which i need to attach a excel file from the local system. I tried to use the attachment control to attach the document. But i am not able to store it into a table. I need to use that excel document for my further processing. I need to get the path from which the data is selected from my local system.
I hard coded the path and i was able to do my operation but now i need to dynamically fetch the data from the location.
thanks in advance
My code for hard coding looks like this
Private Sub Command4_Click()
Dim dbs As DAO.Database
Set dbs = CurrentDb
If (ifTableExists("featuretable") = True) Then
dbs.Execute "Delete * from featuretable"
End If
Dim filepath As String
filepath = "C:\Users\jolly#iese.fhg.de\Desktop\featurevalues.xlsx"**
DoCmd.TransferSpreadsheet acImport, , "featuretable", filepath, True
fmfeaturesubform.Form.Requery
End Sub
"Attach" and "import" are completely different things. i guess you want to import the excel sheet.
one way would be use the Application.FileDialog:
http://msdn.microsoft.com/en-us/library/office/ff196794(v=office.15).aspx
another way would be search your current folder and import matching filenames:
Dim mBaseFolder As String
Dim mFname as string
mBaseFolder = "C:\test\" ' or application.CurrentProject.Path
mFname = Dir(mBaseFolder & "*.xls")
Do While fname <> ""
DoCmd.TransferSpreadsheet acImport, , "featuretable", mFname , True
mFname = dir()
Loop
I import several '|' separated files to my DB with this:
Private Sub cmdImport_Click()
Dim i As Integer
Dim path1 As String
path1 = "C:\ImportFiles"
Destination = "C:\ImportFiles\processed"
Set fs = Application.FileSearch
With fs
.LookIn = Path1
.FileName = "*.*"
If .Execute > 0 Then
For i = 1 To .FoundFiles.Count
DoCmd.TransferText acImportDelim, "ImportRPS", "tbImportRPSTemp", .FoundFiles(i), False
fileName = .FoundFiles(i)
fileName = Replace(fileName, path1, "")
Set fs1 = CreateObject("Scripting.FileSystemObject")
fs1.MoveFile Path1 & fileName, Destination & Format(Now, "YYYYDDMMTHHMMSS") & fileName
Next i
Else
MsgBox "No files to update", vbInformation
Exit Sub
End If
End With
Me.Requery
End Sub
Problem is, the files are in UTF-8 while the access database I'm working with is not, it imports with '' in front of the first record and my table ends looking like this:
Type Nmbr Date
100 12312 15082013
What can I do to import the files whitout problem? Is it possible to convert the file to ANSI and them import it or are there better ways? I can't do it manually because those files are supposed to arrive by the dozens every day.
According to http://msdn.microsoft.com/en-us/library/office/ff835958.aspx the last parameter of TransferText is the code page. In windows UTF-8 is code page 65001.
So, try adding , , 65001 to your DoCmd.TransferText line. I think it should look like:
DoCmd.TransferText acImportDelim, "ImportRPS", "tbImportRPSTemp", .FoundFiles(i), False, , 650001
I don't have the ability to test this code right now, but I believe it should work.
I'm working on a Access database which generates some mails with mail merge called from VBA code in the Access database. The problem is that if I open a new Word document and start the mail merge (VBA), Word opens the same Access database (which is already open) to get the data. Is there any way to prevent this? So that the already opened instance of the database is used?
After some testing I get a strange behavior: If I open the Access database holding the SHIFT-Key the mail merge does not open an other Access instance of the same database. If I open the Access database without holding the key, I get the described behavior.
My mail merge VBA code:
On Error GoTo ErrorHandler
Dim word As word.Application
Dim Form As word.Document
Set word = CreateObject("Word.Application")
Set Form = word.Documents.Open("tpl.doc")
With word
word.Visible = True
With .ActiveDocument.MailMerge
.MainDocumentType = wdMailingLabels
.OpenDataSource Name:= CurrentProject.FullName, ConfirmConversions:=False, _
ReadOnly:=False, LinkToSource:=False, AddToRecentFiles:=False, _
PasswordDocument:="", PasswordTemplate:="", WritePasswordDocument:="", _
WritePasswordTemplate:="", Revert:=False, Format:=wdOpenFormatAuto, _
SQLStatement:="[MY QUERY]", _
SQLStatement1:="", _
SubType:=wdMergeSubTypeWord2000, OpenExclusive:=False
.Destination = wdSendToNewDocument
.Execute
.MainDocumentType = wdNotAMergeDocument
End With
End With
Form.Close False
Set Form = Nothing
Set word = Nothing
Exit_Error:
Exit Sub
ErrorHandler:
word.Quit (False)
Set word = Nothing
' ...
End Sub
The whole thing is done with Access / Word 2003.
Update #1
It would also help if someone could tell me what the exact difference is between opening Access with or without the SHIFT-Key. And if it is possible to write some VBA code to enable the "features" so if the database is opened without the SHIFT-Key, it at least "simulates" it.
Cheers,
Gregor
When I do mailmerges, I usually export a .txt file from Access and then set the mail merge datasource to that. That way Access is only involved in exporting the query and then telling the Word document to do the work via automation, roughly as follows:
Public Function MailMergeLetters()
Dim pathMergeTemplate As String
Dim sql As String
Dim sqlWhere As String
Dim sqlOrderBy As String
'Get the word template from the Letters folder
pathMergeTemplate = "C:\MyApp\Resources\Letters\"
'This is a sort of "base" query that holds all the mailmerge fields
'Ie, it defines what fields will be merged.
sql = "SELECT * FROM MailMergeExportQry"
With Forms("MyContactsForm")
' Filter and order the records you want
'Very much to do for you
sqlWhere = GetWhereClause()
sqlOrderBy = GetOrderByClause()
End With
' Build the sql string you will use with this mail merge
sql = sql & sqlWhere & sqlOrderBy & ";"
'Create a temporary QueryDef to hold the query
Dim qd As DAO.QueryDef
Set qd = New DAO.QueryDef
qd.sql = sql
qd.Name = "mmexport"
CurrentDb.QueryDefs.Append qd
' Export the data using TransferText
DoCmd.TransferText _
acExportDelim, , _
"mmexport", _
pathMergeTemplate & "qryMailMerge.txt", _
True
' Clear up
CurrentDb.QueryDefs.Delete "mmexport"
qd.Close
Set qd = Nothing
'------------------------------------------------------------------------------
'End Code Block:
'------------------------------------------------------------------------------
'------------------------------------------------------------------------------
'Start Code Block:
'OK. Access has built the .txt file.
'Now the Mail merge doc gets opened...
'------------------------------------------------------------------------------
Dim appWord As Object
Dim docWord As Object
Set appWord = CreateObject("Word.Application")
appWord.Application.Visible = True
' Open the template in the Resources\Letters folder:
Set docWord = appWord.Documents.Add(Template:=pathMergeTemplate & "MergeLetters.dot")
'Now I can mail merge without involving currentproject of my Access app
docWord.MailMerge.OpenDataSource Name:=pathMergeTemplate & "qryMailMerge.txt", LinkToSource:=False
Set docWord = Nothing
Set appWord = Nothing
'------------------------------------------------------------------------------
'End Code Block:
'------------------------------------------------------------------------------
Finally:
Exit Function
Hell:
MsgBox Err.Description & " " & Err.Number, vbExclamation, APPHELP
On Error Resume Next
CurrentDb.QueryDefs.Delete "mmexport"
qd.Close
Set qd = Nothing
Set docWord = Nothing
Set appWord = Nothing
Resume Finally
End Function
To use this, you need to set up your Resources\Letters subfolder and put your mailmerge template word file in there. You also need your "base" query with the field definitions in your Access App (in the example, it is called MailMergeExportQry. But you can call it anything.
You also need to figure out what filtering and sorting you will do. In the example, this is represented by
sqlWhere = GetWhereClause()
sqlOrderBy = GetOrderByClause
Once you have got your head round those things, this is highly reusable.
I am attempting to open a document from access, execute a mail merge, and then save the document output from the merge using VBA.
Here is my current attempt:
Dim templateName as String, tempRoot as String
tempRoot = "C:\report\"
templateName = tempRoot & "template.doc"
Dim objDoc As Word.Document
Dim objWord As New Word.Application
Set objDoc = objWord.Documents.Open(templateName)
objWord.Visible = True
exportData "AnnualData", tempRoot & "annualData.txt" 'Outputs query to txt file for merge
objDoc.MailMerge.OpenDataSource NAME:= _
tempRoot & "annualData.txt", ConfirmConversions:=False, ReadOnly _
:=False, LinkToSource:=True, AddToRecentFiles:=False, PasswordDocument:= _
"", PasswordTemplate:="", WritePasswordDocument:="", _
WritePasswordTemplate:="", Revert:=False, Format:=wdOpenFormatAuto, _
Connection:="", SQLStatement:="", SQLStatement1:="", SubType:= _
wdMergeSubTypeOther
objDoc.MailMerge.Execute
objDoc.Close False 'Ideally after closing, the new document becomes the active document?
ActiveDocument.SaveAs tempRoot & "testReport.doc" 'And then save?
Set objWord = Nothing
Set objDoc = Nothing
I get the merged document, however, I am unable to save it. I receive an error stating that the command cannot be performed when no document is open.
If anyone can provide any suggestions, it would be appreciated.
Changed ActiveDocument to objWord.ActiveDocument. Ended up with the desired results.
Thanks Remou.
I just went through this. Here's what I'm doing and it works well. oDocument is the merge form that the user selects via an open dialog box. The excel file is the query that I've previously exported and stuck in the users temp folder. I tried this technique with Access queries and temp tables, but found that using excel was much more trouble free.
The Sleep command is from an imported system dll function ( Public Declare Sub Sleep Lib "kernel32" (ByVal dwMS As Long) ) and gives Word time to run the merge. Actually, that may be all you need. This is using Office 2007.
If Not oDocument Is Nothing Then
' get merge source file
Set oFSO = New FileSystemObject
Set oFolder = oFSO.GetSpecialFolder(TemporaryFolder)
strTempFile = oFolder.Path & "\PTDMergeSource.xls"
' run merge
With oDocument.MailMerge
.MainDocumentType = wdFormLetters
.Destination = wdSendToNewDocument
.OpenDataSource strTempFile, WdOpenFormat.wdOpenFormatDocument, False, False, False, False, , , , , , , "SELECT * FROM `tblMerge$`", , False, WdMergeSubType.wdMergeSubTypeAccess
.Execute True
End With
Sleep 2
oDocument.Close False
Else
MsgBox "Action was cancelled, or there was an error opening that document. Please try again, then try opening that document in Word. It may be someone else has locked that document (they are editing it). If the problem persists, email the document to the support contractor."
End If
