Remove All Connections?

Feb 9, 2010

I've got a little program which uses webqueries to import data from anywhere between10 and 200 web pages. It's working pretty well, but I need a way to clear out the residual connections via the code.

The part of the macro which imports the data was simply recorded and very slightly modified. I've included it below... but what I'd like to do once the data has been imported is delete the connection.

DB Connection Lockout Other DB Connections

Mar 7, 2007

I have a series of external database connections that I run in Excel, connecting to a Server based DB and running some SELECT statements. (ingres). We may have up to dozen of client machines accessing the ingres DB at any time. All is good at this point but when excel goes to INSERT some calculated data back to the main database, it appears that my Excel spreadsheet connection is locking the database when it connects, keeping other people from using their client connections.

first question: Does anyone know if the connection excel uses to run sql statements via external database connection will indeed prevent other users from connecting to the main database?

second question: if so, is there a setting or something that can make excel more "passive"?

How To Enable Data Connections

Dec 16, 2011

I have a workbook which uses data connections to our sage accounts product. Everytime i open the sheet i get the "Data Connections have been disabled" security message, and need to go in and enable them. Is there any way of enabling the data connections by default? I only want to do it for this one workbook - i still want to be prompted when i open other workbooks.

Access Databse Connections In VBA

Jul 22, 2006

From within VBA I need to open a database connection and issue a select and store the results in my spreadsheet. The issue is that I only JUST learned that you can do this and I dont know where I can look for instructions. Incase it matters, I am trying to connect to a Sybase DB. I have used perl, c# and a little bit of Java to do this but never from with in Basic (let alone basic within excel!)

Close Data Connections After Refresh

May 3, 2013

I currently have a spreadsheet that has data connections to a file on a shared drive. On opening the file I have it update the data connections so that the data needed is always correct. The file I use is to be distributed out to work colleagues to use and on testing it works really well apart from if you have the file open and somebody tried to open the original file where the data is pulled from for the connection. It says it currently in use by 'another user'.

Is there any code to add to workbook_open that will close/disable the data connection links once the data has been updated? The code I currently have is this:

VB:
Private Sub Workbook_Open()
ActiveWorkbook.RefreshAll
Application.Wait Now + TimeValue("00:00:02")
Userform1.Show
End If
End Sub

What this basically does is gives it time to refresh the data connections and show a progress userform. The only thing is the connections stay live and I don't want that as the connection file is then locked. I'm hoping its something simple like ActiveWorkbook.CloseDataConnection added in after the userform has been shown (or something along them lines ). Also the data connections would have to be able to reconnect on open so that they can refresh again.

Defining Column Reference With ADO Connections Using VBA

May 16, 2008

It extracts Employee ID's and there Names from our database and lists them in columns A:C

What I want to do is list the ID's manually and get it to extract only the Names for the ID's I listed in Column A...

I am not sure how to amend this code to look at ID's listed in column A instead of extracting the whole database.

I know I need to add a "WHERE ID =" clause in the SQL but not sure how to say WHERE ID = A1, A2, etc.

Editing Data Connections In 2003

Oct 20, 2009

I have a workbook with multiple worksheets and over 25 Data Connections using MS Query to connect to different tables in an SQL Server database.

The problem is that the SQL Server database is now being moved to a different server. The database name and the schema of the tables will be unchanged. Only the server name needs to be changed from XXXXX to YYYYY.

I have been unable to find a way to successfully edit the data connections in Excel 2003. A web search produced one potential option. However, that did not work for me very well. Thought the code is designed to cycle through all tablequeries and pivotqueries, the change is only made to one of the data connections. Here is the option I tried:

http://support.microsoft.com/kb/816562

Note that it is very easy to edit data connections in Excel 2007. So I also tried opening the .xls file in Excel 2007. I used the Data Connections button under the Data tab in the ribbon and was successful in editing the connections to point to the new server. However, the graphs used to display the queried data behave weird. The "format axis" settings and chart sizes change. In general, default display settings for charts seems to differ between Excel 2003 and 2007.

I used Excel 2007 to only edit the data connections and saved the workbook in the original .xls format

VBA To Change Workbook Data Connections

Jun 2, 2014

My issue is we have a remote office, using an access DB which links to an Excel file. We sometimes send the files to other people to make changes, but the link is then broken (it was a network location).

You can just change it manually, or accept the many prompts that come up, but it needs doing at each end, each time.
I thought I'd do a routine to change the connection paths, this is what I have...

Code:
Sub alan()
Dim i As Long
Dim cnt As Long
Dim modtext As String, modfile As String
Dim modrange As String, OldPath As String, NewPath As String

OldPath = "\192.168.1.100MultimediaCommissioning Folder"
NewPath = "C:matts"

[Code] ...

I added the sourcedatafile part to the routine afterwards, because the connection string part worked fine. But I now get Run-time error '1004' Application-defined or object-defined error...

External Data - Cleanup Existing Connections

Apr 26, 2013

While making my first foray into defining external connections (to an Oracle database) I ended up with an "Existing Connection" that reports "File could not be opened. It is either damaged or the file format is not valid. Try opening the application that created it and saving to a new file." Followed by "Unable to open or read this connection file. Either the file has been damaged or the file format is not valid."

Ok, fine. So how do I delete it? There seems to be no option for that in the "Existing Connections" dialog. A search for a *.odc or *.udcx file doesn't turn up anything with the name of this connection. A search of the registry doesn't turn up anything.

Slicer Connections Lost When Copying To New Workbook

Jun 12, 2014

The main objective of the code is to create different workbooks that are going to be send to different people(with only their data).

I am using the filter to delete the data that I don't need and then create a new workbook, save it and close it. This has been working fine.

The issue is that I have two slicers in the 'DistMenu' sheet. When I open again the newest workbook, they slicers are disconnected to the pivot tables. This can be fix manually by selecting the slicers --> PivotTables Connections etc

I use the macro recording to get a code and work from there, but is giving me error '1004' "Unable to get the PivotTables property of the Worksheet class".

Macro To Delete All External Data Connections

Mar 31, 2009

I am trying to write a macro to delete all connections from a very large excel file

I created this file by using a Macro to extract data from a external data source (url's listed on a sheet)

The issue is the 1000+ connections on this file make it next to impossible to operate

I cannot recreate the file

macro to delete all connections in all sheets in a given work book.

[URL]

Macro used :

Sub Dump()
Dim myURL
Sheets("Sheet1").Select
ActiveCell.Offset(1, 0).Select
myURL = Worksheets("Sheet1").Range(ActiveCell.Address).Text
Sheets("Sheet2").Select
Range("A65536").Select

Create UDF For Currency Conversion With VBA Only - No External Connections

Feb 15, 2013

The main objective is to create a, UDF with 2 parameters (Currency, Date) in order to display currency exchange rate based on the currency and date. Let's say I want to find an exchange rate between USD/ EUR, then I would have a formula something like "=FX(EUR, 12/31/2011)". All currencies will be against USD.

The trick is that it will have to be created as Add-On so that it can be used in any Excel spreadsheets. The second trick is that I cannot have VBA to make any internal connections to other workbooks or applications.

So the only thing that I can come up with would be to write a VBA code that would include all values and currency rates in it. The structure that I have in mind would be something like:

Code:
Function Fx(Vl As String, Dte As Date)
Dim Rte As String
If Vl = "EUR" And Dte = "12/31/2011" Then
Rte = 0.7723
ElseIf Vl = "EUR" And Dte = "12/31/2010" Then
Rte = 0.7546

[code]....

The above code does not work!There will be at least twenty different currencies and at least 15 periods.

VBA - Save File As New Workbook BUT Without Existing Data Connections

May 23, 2013

I'm trying to use vba to create an offline backup file for a sheet that is linked to an access database. the code I have is simple and worked for a file that is not linked to any database.

Code:
Sheets("Data").Select
Sheets("Data").Copy
Application.DisplayAlerts = False
ActiveWorkbook.SaveAs Filename:=myfilename
Application.DisplayAlerts = True

Now that I insert it into the actual file, which is linked to the database I get an error. I also tried to move the display alert up, before the select instructions, but also this does not work. this is not what I wanted since I want this file not to possibly connect to any database.

Opening Excel Workbook With Embedded Connections Using VBA And Auto Refreshing

Apr 3, 2014

I have an Excel Workbook with Showcase Queries embedded into it.

Upon a manual open, the user is prompted to either refresh data or keep data since last save, the user then has to enter a username and password to allow the query to access the database.

Using the code below to open the workbook, no such prompts are given. Is the code overriding the prompts and automatically refreshing the data without password? [Given nature of data, visual validation of refresh is not possible]

If not, how can we code a data refresh through showcase query with user/pw req's?

Removing Data Connections And / Or Query Tables Before Saving File?

Oct 10, 2013

I've tried to remove connections after saves and have been unsuccessful.

HTML Code:
' Delete Additional Connections
' If ActiveWorkbook.Connections.Count > 0 Then
' For i = 1 To ActiveWorkbook.Connections.Count
' ActiveWorkbook.Connections.Item(1).Delete
' Next i
' Else
' MsgBox ActiveWorkbook.Connections.Count
'
' End If

HTML Code:
' Remove named ranges
For Each nm In ActiveWorkbook.Names
nm.Delete
Next nm

I've tried both of these and the Excel file is still attached with XML to the query table. I get an error message saying the format is different then if you click okay it shows its connected to the database still. Is there an aggressive command that will severe all connections before saving? What commands to run to stop this connection after save to another workbook?

Remove Non-alpha Characters From Alphanumerics With Option To Remove Numbers

Aug 8, 2009

I have found a very useful UDF for removing non-alpha characters from strings. (See below, Credit for posting to Stanley D Grom - Ozgrid post ´Removing Non-alpha Characters From Text´).

Option Explicit

Private Function RemoveCharacters(InString As String) As String
Dim intLoopCounter As Integer
Dim intStringLength As Integer
Dim intASCIIVal As Integer
intStringLength = Len(InString)
InString = LCase(InString)
For intLoopCounter = 1 To intStringLength
intASCIIVal = Asc(Mid(InString, intLoopCounter, 1))
If intASCIIVal >= 97 And intASCIIVal <= 122 Then
RemoveCharacters = RemoveCharacters + Mid(InString, intLoopCounter, 1)
End If
Next intLoopCounter
End Function

Two requests:

1. Could the UDF be modified such that any part of a string contained within brackets is also removed (e.g. "NLGA High Street (West-Enfield), EN6" becomes "nlgahighstreeten")?

2. Can an argument be added to the format of the UDF, such that numbers (0 to 9) are either included or excluded (e.g. RemoveCharacters(A1,1) where the argument ´1´ would include any numbers (0 to 9), so "NLGA2003 High Street (West-Enfield), EN6" becomes "nlga2003highstreeten6")? ´blank´or ´0´would exclude these numbers, i.e. would return "nlgahighstreeten"

I really do not understand why I was banned. I've downloaded utility from THIS forum and have kindly asked help on how to remove it because it does not meet my needs. I am not an expert in VBA and expected that somebody could help me. (It looks like the person providing the utility in the above indicated post shared the password as everybody is thanking him but I don't see where it is!)

I just want to remove the utility from my PC!!! And, if I can do this without bloody password than I do not want it! But, can somebody just explain me if there is another way to remove this from my PC or I have to reinstall EXCEL ?

I must say that I find it really increadible for beeing banned twice for no reason. Isn't it worse to place the password protected utility so that the one dowloading it cannot remove it anymore?

In my Working Sheet, first It will take the value from the Data Sheet. Since the number of Acc / Balance may differ, I wan to know how to remove the 0 and #Num! for those null values.

Following that, I create a column sorting the all number from smallest to biggest, following by next column forming up the string. I do not want the same Acc to repeat in the string.

It is my intention to simply enter monday in the day colum in the expenses detail sheet and in the weekly business sheet it would pick this up.

So the formula I had was =ifsum(!expenses detail a2:a40, !expenses detail monday, e2:e4) This formula is giving me a name error.

Am I using the wrong formula. Basically I want this type of formula so under the expenses row for mon-sun it will add this up.

Remove Add-In In 2007

It's on the Add-In tab (obviously!) and the Command Group is named 'Custom Toolbars'. What's annoying is once I close the document, the Add-In stays there and I have a redundant tab with an irrelevant Command Group .

Now, I've done a bit of searching and how found a number of websites that give instructions on add-ins. However, the add-in that has come with the client's document isn't on the list and hence I can't remove it. I need to do to get rid of this? I've contacted the client, but they're suspiciously quiet about the whole thing.

Remove Many Rows At Once

Apr 4, 2014

I am using the following code to remove an entire row if a specific cell in that row contains "remove":

iLastRow = Cells(Rows.Count, "D").End(xlUp).Row
For i = iLastRow To 1 Step -1
If Left(Cells(i, "D").Value, 4) = "remo" Then
Rows(i).Delete
End If
Next i

However, from what I can see, it starts from the bottom and look upward, removing each line as it finds it. The problem is, there could be upward of 500 lines that need to be deleted. This coding looks and removes lines one at a time and can take a while. Is there any way I can get this done faster?

During the previous steps of my macro, I sort the column (Column D) that has the "remove" in it, so all of the "remove"s are adjacent to each other in Column D of my file.
