Open Excel File Stored In Access Database
Feb 8, 2007
I need to open an Excel file that has been stored in the Access Database using the insert Object functionality of MS Access manually.
What i am aware of is that i cant just read the field containing the Excel File into a Byte Array and pass it to the Excel object in C#,as the file is wrapped in the OLE Wrapper used by Access while inserting the file in database.
I have tried locating the Header of Excel file from the byte array and read the file from there on but it is not working.
while (true)
{
if (0xE11AB1A1E011CFD0 == BitConverter.ToUInt64(byStream, i))
break;
i++;
}
output.Write(byStream, i, byStream.Length - i-1);
byStream is a byte array into which i have read the Excel file from Database.
I am locating the Excel file header in the byte stream and am writing the byte array to a file from that location.But on opening the written file it dosent work.
Similar approach had worked in case of Images but now in this case.
Can some one please tell me as to how i can open the Excel File.
Can I use Interop.Access object to achieve the goal??

I want to delete an excel file from within access vba. Problem is that if the file is open, it obviously cannot be deleted. so I need to check to see if that specific excel workbook is open and if it is, I want to close it before I can delete it.
All of the answers here involve creating an excel object and opening it before closing it. If I do that all that happens is a second instance of the workbook opens then closes leaving the originally open workbook still open.
Sub xx()
Dim XLapp As New Excel.Application
Dim ObjXL As Excel.Workbook
Set ObjXL = XLapp.Workbooks.Open("C:dropboxexcelimport.xlsx ")
ObjXL.Application.Visible = True
[Code] .....
The above code demonstrates my problem, if the import.xlsx file is already open then the code just opens another instance of this workbook and then closes it again leaving the original workbook open and as such cannot be deleted.

I am currently using Access 2010, and have successfully split a database, using the Access wizard.However, whenever a second or third user opens the database - with their front-end database file - they encounter the following message;The Microsoft Access Database engine cannot open or write to the file ". It is already opened exclusively by another user, or you need permission to view and write its data.
I have researched the internet and see that it has something to do with network permissions. I have worked with my IT department and this appears to be resolved!
Is there a setting I need to check in the front-end and/or back-end copies of the databases?Why is there no file name in the error message?

I am trying to open a workbook with a command button on a form however the path to the file is giving me a fit. The path for the file location contains spaces and I am going blind trying to figure out how to rectify the path. Heres the line. I am sure someone here will see this problem quick! Thanks.
Private Sub Command0_Click()
On Error GoTo Err_Command0_Click
Dim stAppName As String
stAppName = "Excel.exe N:OPSCOMMONOpsResearchContact CenterDI CCL Reporting dBApps by Agent.xls"
Call Shell(stAppName, 1)
Exit_Command0_Click:
Exit Sub
Err_Command0_Click:
MsgBox Err.Description
Resume Exit_Command0_Click
End Sub
Heres the mess I made out of it:
stAppName = "Excel.exe N:OPSCOMMONOpsResearchContact" & Chr(32) & "CenterDI" & Chr(32) & "CCL" & Chr(32) & "Reporting" & Chr(32) & "dBApps" & Chr(32) & "by" & Chr(32) & "Agent.xls"""

halloo everybody
Here is my code to check an excel sheet wether it is open or not.
It is working good in the following situations.
1.if the excel file is not yet opened. then it is opening and bringing a value from some cell of the sheet1.
2.If the file is already opened and not yet closed. it is not opening again it is understanding that the file is already openrd and bringing the cell value.
3.It is working when it is closed by the user and again clicked the button to open. It is opening and bringing the value.
4.NOW the problem starts.
IT IS NOT WORKING , If I click the button again to open. It is opening another copy of the same file. I did't understand why is it working perfectly? before I close the file and not working if I close the File.
please kindly check my code and respond to me .
here is my code but it is not working when the file is already opened.
Private sub Cmd_Click()
Dim XL As New Excel.Application
Dim wbk As New Excel.Workbook

WorkBookName = "Book2.xls"
If Not WorkbookOpen(WorkBookName) Then
chk = 1

I have a button in the form of the current access file. What I want to do is when the user click on the button,
triggered the vba to backup current access file. But since the file is currently open, is this possible? If yes, may I know how to do it with vba?
I have tried two methods but failed:
1) Use copytofile method, but I get permission denied due to file open;
2) Use dbengine.compactdatabase method, but it also has problem if the file is open.

after I upgraded to win 7 my database refuses to use an .mda file, to which I refer to (Visual Basic menu, extras). I get the message that I should have installed this .mda file with administrator rights. I am the only user and administrator of my computer, and i cannot install this file (which I bought a long time ago) other than put it either into ....../office12 or into windows/system12 or windows/syswow64.I tried to register it under DOS (with administator rights) with regsvr32.exe but there I got the message that I should check whether this .mda is a 32 or 64 bit version.

I have a a database with a large number of email addresses in it.
I also have a list of email addresses stored in an excel file.
I would like to take the excel file and use it to check for the same email addresses in the access database and if they are present in the database add content to another field in the database to flag it.
Can anyone help?
Thanks.

Cannot Open Database". It may not be a database that your application recognizes, or the file may be corrupt. I have a colleague that is using Microsoft Access to import objects from SQL server but he's getting the above error. I've checked the login my colleagues uses and it has all the right permissions ect but I cannot seem to figure out why this error is still happening. Is it something to do with the SQL server or Microsoft Access?

I have created a database with approximately 30 columns, 1st column being a primary key. At the end of the database there are 5 columns. We will call them VWXYZ.
One of my users wants to be able to update VWXYZ via importing an Excel document to the existing table. He does NOT want fields 1-25 updated. He is editing his Excel document to only include the primary key and then VWXYZ with the same exact column names. When he imports, it sets 2-25 to blank and updates VWXYZ to the updated information.
How can he import an Excel document that only updates VWXYZ?

All of the sudden I get an error message when I try to open my database from a file rather than through Access. If I open Access first and open the file that way, there is no problem but if I click on it from Windows Explorer, I get the error.
See picture.

We have a new user who is unable to get into a database. Another user in the same office had no problems.
The other user is using:
"C:Program Files (x86)Microsoft OfficeOffice14MSACCESS.EXE" /wrkgrp"ServerNameShareNameSFTPSFTPWorkgroup.mdw" "C:SFTP Database V2.1 FESFTP Database V2.1 FE.mdb
The new user was not able to access the share at all using ServerNameShareNameSFTP until he changed the path to:
"C:Program Files (x86)Microsoft OfficeOffice14MSACCESS.EXE" /wrkgrp"ServerName.ACCT05.us.companyabbreviation.comSha reNameSFTPSFTPWorkgroup.mdw" "C:SFTP Database V2.1 FESFTP Database V2.1 FE.mdb"
Now he can get into the SFTP folder, but when he uses the shortcut, he gets an error stating Microsoft Access couldn't find the file ServerName.ACCT05.us.companyabbreviation.comSha reNameSFTPSFTPWorkgroup.mdw 1" "C:SFTP Database V2.1 FESFTP Database V2.1 FE.mdb" (Note the space and 1)
I created a new shortcut, and I was able to open the db using his target line, even though I can use the shorter one. For the new user, this still generates an error.

I am not an experienced Access developer.
I have a .mdb file that was created with Access 2000. Before I upgraded to 2003, I opened the file source by holding down 'shift' and double clicking the file. Now when I do that, it runs the application. How can I open the source file again.
Thanks

I have created a database for a church cemetery. It contains the usual names, birthrates deaths, etc.... I have also created a map of the cemetery in PDF format with the lot number highlighted which is assigned to a particular record. I did the same in excel with a layout of the lot and a JPEG picture of the grave marker. In my table I created Three columns - Site Plan, Lot Plan, and Grave marker. I insert the specific site plan, lot plan, and jpeg picture using the "insert object" in the table. On my form after a search, I have created three buttons.. Site Plan, Lot Plan & Grave Marker.
I have looked and experimented trying to assign these command buttons to open these files on the form. I don't have any experience with macros or VB code.

Good Afternoon,
Does anyone know where I can find a sample db that will let the user do the following:
Selected a file from their computer and upload to a the same folder as the db?
I am building an Investigation database. This function will allow the user to attach file to an investigation. (the files will be stored in a folder and logged on a table)
Any help would be great.
Thanks,
Bones

We have a database on our network server which I cannot open. I get the following error everytime I try to access it.
This file is located outside your or on an untrusted site. Microsoft Access will not open the file due to potential security problems. To open the file, copy it to your machine or an accessible network location.
I think it has to do with a Microsoft Jet 4.0 Service Pack 8 security update. However, I cannot find the update to uninstall. Others can access the database located on the network, but some get a pop-up that allows them to say "no" and access the file. The pop-up has the following message:
Security Warning: Unsafe expressions are not blocked. Do you want to block unsafe expressions?
Can anyone help with this?

The file is part of a students exam, so a bit urgent!
The file just will not open, either by double click or open in Access. Tried holding shift, not the problem, not hidden or anything, just that trying to open brings up the first warning box (we have very strict security on students computers!) but after that nothing, no sign of an error or anything having been loaded. Tried compress & repair and the microsoft tool for compressing JET files, that did give an error when it tried, just saying error compacting database.
I've tried importing the file into a new database using access, that gives no results, but importing tables into excel does!
Anyone anyideas short of paying for it to be done?
:confused:

Is it possible to open a pdf file that has been saved on a server?
What I have is a table that lists all of the files that have been saved to pdf. There is a column in that table that lists the exact path and file name. There is a combo box on a form that lists those file names. I need to know if there is VB code that will use that specific file name listed in the combo box and open (to view) the pdf file on the server.
Thank you so much for any help and insight provided.
