Access 2007 - Display PDF content on a form - ms-access

On Access 2007, is there a way to display the content of a PDF, even if it is just the first page, on a form? This PDF saved in a table as attachment.

Disclaimer: This answer will only work for PDF files stored outside of your database as separate file. They can be located over a network connection, but I do not know how to access them directly from your database table. This site gives a thorough guide to using the attachments, but doesn't show how to actually display them automatically. It is likely functionality not provided by Access.
You can display anything Internet Explorer can display with a Microsoft Web Browser Control.
Once you've added the control, you can navigate to whatever you want to display during the load or open event of the form.
For example, if the control is called WebBrowser0 then the following would work:
Private Sub Form_Load()
Me.WebBrowser0.Navigate2 "C:\example.pdf" 'Substitute the actual address here.
End Sub
This is an extremely versatile method for displaying other content within Access. You can find more information here.

The only two methods I know of for previewing a PDF (WebBrowswer as suggested by Daniel and the Adobe Active X control) require a file path to be passed to the control.
I recommend extracting the file from the attachment field and saving it to a temporary location such as C:\Documents and Settings\username\AppData. This can be found by using the vba Environ command.
Extracting the file is done with the SaveToFile method in the embedded DAO recordset (which is how attachments are stored in memory).
Example Code
Assume each record has a field called AttachedFile and each record has only one attached PDF. The form is using a WebBrowser control named PreviewBrowser to view the PDF
Private Sub Form_Current()
On Error GoTo ExitSub
Dim FormRS As DAO.Recordset
Set FormRS = Me.Recordset
Dim RecAtt As DAO.Recordset
If (Me.AttachedFile.AttachmentCount > 0) Then
Set RecAtt = FormRS.Fields("AttachedFile").Value
RecAtt.OpenRecordset
Dim Path As String
FilePath = Environ("APPDATA") & "\Preview.pdf"
If (Dir(FilePath) <> "") Then Kill FilePath
RecAtt.Fields("FileData").SaveToFile FilePath
Me.PreviewBrowser.Navigate2 FilePath
End If
ExitSub:
RecAtt.Close
End Sub
Of course the code needs to be a bit more complicated if there are multiple attachments to a given record, but that would be done by manipulating the RecAtt recordset.

Problem Importing Excel File into Access via VBA

I've created a multi-user Access Form that will essentially be open for most of the day on several peoples computers. On this form, I've created a button that will import an excel spreadsheet via VBA. The code is:
Option Compare Database
Private Sub Command0_Click()
DoCmd.SetWarnings False
DoCmd.RunSQL "DELETE ExcelTable.* FROM ExcelTable;"
DoCmd.TransferSpreadsheet acImport, acSpreadsheetTypeExcel12Xml, "ExcelTable", "C:\Users\JohnDoe\Documents\MyTable.xlsx", True, "Data!A6:DB" & numberofrows
DoCmd.SetWarnings True
End Sub
This code imports the data fine. However, users will frequently need to update the spreadsheet throughout the day. There are 2 problems that I am frequently running into:
If a user attempts to overwrite the original spreadsheet with an updated version, they receive an error message "Cannot access read-only document".
If the user attempts to open the spreadsheet, they receive the error message that the excel file is locked for editing.
I was under the impression that by running the above VBA code, the user is importing a static table (not a linked table), meaning that once the table is imported into Access, it's no longer referencing the original Excel file.
How do I get around these error messages?
The users will need to update the excel file several times throughout the day and right now, everyone has to completely exit Access in order to access the original excel file.

Display PDF in Report

I want to display dynamically .pdf files like pictures in a report, it should look like this:
i already tried with webbrowser, but then it doesn't show up in the preview or when i print the report out...
I also tried a ole unbound object, also no success, here the code i had in the Report_Load event:
Dim vPath As String
vPath = GetNewestDocument(Me!artNr)
'Returns path for pdf file, about:blank if there is no file.
If vPath = "about:blank" Then
Me!PDFBrowser.visible = True
Me.PDFBrowser.SourceDoc = vbNullString
Else
With Me.PDFBrowser
.OLETypeAllowed = acOLELinked
.SourceDoc = vPath
.SizeMode = acOLESizeStretch
End With
End If
EDIT:
With "I want to display dynamically ..." i meant to change dynamically pdf's in the Report.
EDIT 2:
I just found out that the type of the OLEunbound object is embedded, but i think this one should be linked as i read in other Forums:
When i try to Change it gives error: "This property can not be changed because it is read-only"
You could get a licensed version of Adobe Acrobat (not Reader) and control it programmatically to capture the images you want.
Alternatively, you could use the VBA Shell Function to call a command-line PDF converter like 2Jpeg to programmatically (and dynamically if necessary) convert the PDF to an image (see this), or even "print" the PDF to an image file using the correct driver (see this).
Once you have an image file, you can easily load the created image to your Access form with VBA, perhaps with this.
Without further information (and answers to my previous questions) I can't offer more suggestions at this point but I hope that helps!

Creating a Document Database using Microsoft Access

I am attempting to create a table within a database which store all of the documents related to the database "in it". What I really want to do is have a file uploaded and have vba code which copies the file to a network location, renames the file by concatenating two fields from the document table form (eliminating the issue of duplicate file names in the external location), and then stores the file name and file path in a file path field in the table. I am very new to access and vba so I am having difficulty getting everything to work. The code I currently have is below:
Option Compare Database
Private Sub Command15_Click()
Dim f As Object
Set f = Application.FileDialog(3)
f.AllowMultiSelect = False
If f.Show Then
For i = 1 To f.SelectedItems.Count
sFile = Filename(f.SelectedItems(i), sPath)
MsgBox sPath & "---" & sFile
Next
End If
End Sub
Public Function Filename(ByVal strPath As String, sPath) As String
sPath = Left(strPath, InStrRev(strPath, "\"))
Filename = Mid(strPath, InStrRev(strPath, "\") + 1)
End Function
I can not seem to get a handle on how to move, rename by concatenating the two fields from the form, or store the path in the path field of the table. I have been to the following locations to obtain what information I could
ms access browse for file and get file name and path
VBA to copy a file from one directory to another
I am currently using Microsoft Access 2010, and I do not wish to use the file attachment field type because of database size constraints. Currently I press a button and a file explorer appears to navigate to the file being uploaded, and the path and file name are entered into strings. After this point I am lost. If any other information is needed please let me know. Thanks in advance for the assistance.
I believe your approach to managing the documents is right. In most cases, it doesn't make much sense to store documents in the database itself when the filesystem is a more suited to this job.
What you are doing is fairly straightforward but the main complexity will come from the correct management of the various paths and filenames and extracting the right information from them.
It can become tricky if you're not using some helper functions to to dissect and recompose the various bits of the paths.
I have created a sample database that has a few functions. Might not be exactly in line with what you need but you can easily play around with it to suit your particular case.
The sample database includes a Tools VBA module that has a few useful functions to split a Path into its constituents.
Basically, the database has 2 forms.
The main form allows you to set the network path where the files are to be saved.
You can then select a pre-defined Account number (listed in the Account table) associated with a document, then click the upload button.
This creates a new record in the Document table and opens a form where you can edit the document title and click a button to upload a file to the server.
The file selected by the user is copied to the server after its path has been transformed.
I took the assumption that the file would keep its original extension, the filename would be renamed to the ID of the Document record where the file information is saved (like 5845.pdf) and that the folder where the file is saved on the server would be the account number, so that a source file selected by the user
C:\Users\user\Desktop\SuperSecretFile.pdf
would be saved as, for instance:
\\docserver\files\123-55547\5845.pdf
The Main form also allows you to update an existing record, open the file from the server, open the server's folder where the file is located or even copy the server file back to the user's computer with the original name of the file.
I'll let you play around with it. Let me know if you have any issues.

VBA Open several HTML files in Spreadsheets only in the Workbook currently open

I am downloading HTML files using VBA and Python. These files are on a file directory like C:\files. Every download gives me about 7 - 12 HTML files.
What I want is a way to open each HTML file on one workbook the one which i currently work with.
By using the Open function of VBA for every HTML file i get a new workbook which creates congestion and mess.
Is there a way to have a command inside the loop which opens the HTML file on new tab and inside the current workbook?
I can think of two options: move the sheet from the new workbook into the current one each time; or look at using Querytables.
Moving the sheet is straightforward:
Dim wb As Workbook
For Each varFilePath In colFilePaths 'whatever your loop logic is...
Set wb = Workbooks.Open(varFilePath)
wb.Worksheets(1).Copy Before:=ThisWorkbook.Worksheets(1)
wb.Close False
Next varFilePath
The other option, Querytables, is designed to extract data from HTML rather than just create a worksheet that looks close to how the HTML will render in a browser. Generally the results won't look the same as the webpage, but you do get more control. This may or may not be helpful depending on what you are going to do with the data afterwards. See the VBA documentation for QueryTables for more info, but the basic steps are to create a new QueryTable pointing at your file and the destination cell, set options, and then call its Refresh method to populate cells:
'inside your loop...
Set ws = ThisWorkbook.Worksheets.Add
Set qt = ws.QueryTables.Add("URL;file:///" & varFilePath, ws.Range("A1"))
'set various options here...
qt.WebFormatting = xlWebFormattingAll
qt.WebSelectionType = xlEntirePage
'Get the data
qt.Refresh

Storing PDFs in MS Access Database using Forms

I need to store PDF files in an Access database on a shared drive using a form. I figured out how to do this in tables (using the OLE Object field, then just drag-and-drop) but I would like to do this on a Form that has a Save button. Clicking the save button would store the file (not just a link) in the database. Any ideas on how to do this?
EDIT:
I am using Access 2003, and the DB will be stored on a share drive, so I'm not sure linking to the files will solve the problem.
We have several databases that contain 10's of thousands of documents (pdf, doc, jpg, ...), no problem at all. In Access, we use the following code to upload a binary object to a binary field:
Function LoadFileFromDisk(Bestand, Optional FileName As String = "")
Dim imgByte() As Byte
If FileName = "" Then FileName = strFileName
Open FileName For Binary Lock Read As #1
ReDim imgByte(1 To LOF(1))
Get #1, , imgByte
Close #1
If Not IsEmpty(imgByte) Then Bestand.Value = imgByte
End Function
In this case, Bestand is the field that contains the binary data.
We use MS SQL Server as a backend, but the same should work on an Access backend.
If you used the same concept but upsized to SQL Server- storing PDFs inside of an Image datatype (or varbinary(max)) then you could SEARCH INSIDE THE PDFs using Full Text Search.
I show that Microsoft says you can do this for any file type where you can register an IFILTER product.. and I just was at the Adobe website the other day and say that their Acrobat IFILTER is indeed FREE.
Maybe this will help: ACC2000: Reading, Storing, and Writing Binary Large Objects (BLOBs).
What they do: Read a file in chunks and add it to a blob using a VBA function.
A field of OLE Object, by default would use a Bound Object Frame on the form. Right click on it and you can Insert an object. It comes complete with browsing for the file. Double-click on the field and the actual document will open.
I recommend going with David's advice and link. Unless you have a need to transfer a single file and want all the PDF's included. Size and performance will be an issue.
If security is an issue and the Access file is the only control you have (You are unable to set security on the folder containing all the linked files.), then you would have to embed.
