I recent was asked the following question in an UtterAccess forum and thought the solution could be useful to someone else down the line.
I have an access database with hyperlinks to many protected word documents (write protection only).
The target is : user enters a search string in access and selects specific protected document.
In the thread I developed 2 possible solutions: (1) Open the document and highlight the search term throughout the document, (2) Open the document and the start the Find dialog and allow the user the control of what they do from that point on.
Open the document and highlight the search term throughout the document

Yet again today, I was asked in a forum the infamous question regarding how to disable the security warning that pops up when trying to automate e-mails. So I thought it was time to make this post on my site to help everyone that has this question.
Anyone that had the pleasure of trying to automate sending e-mails using automation (SendObject method, Outlook Automation) had the pleasure of the following security pop-up.

So basically, Microsoft has thrown a stick in developer’s wheels in the hopes of stoping malicious software from propagating unbenounced to the user.
So the question remains, what is a developer to do to make a seamless e-mail tool? Well, as usual, there are a couple possible solutions:
Solution 1 :: Click-Yes
One option would be to download and install a piece of software such as ClickYes. The problem with this is that it can effectively make you vulnerable to propagating malicious software… since it effectively will always authorize any access, whether the request comes from your app, or not. This also requires installation on every computer that will require sending e-mails automatically. In a controlled environment, this can be done, but for general users, this will not be a viable option.
Solution 2 :: Outlook Redemption
Another popular option is to use Outlook Redemption to send your e-mail. The downside here is that it require registering a COM library and then recoding your e-mail automation routine. The positive aspect here is that there are lots of examples available online!
Solution 3 :: Swicth E-mail Techniques
In my opionion, this is the easiest and best solution. Simply stop sending e-mails through Outlook altogether. The major downside here is that since you don’t send the e-mails through Outlook, you will not have a copy saved in your Sent Items. The pros is that it works! It works seamlessly! You could switch over to CDO mailing techniques, use BLAT, use WinSock, … Tony Toew’s covers a number of possible alternate techniques on his site http://www.granite.ab.ca/access/email.htm.
So at the end of the day, there are several solutions available to get around this problem.

I see frequently asked on various forum questions regarding pulling information off of websites. The concept is relatively straight forward, load a page, grab the content, parse what you need… You can use various need, get into textual parsing, DOM manipulation and extraction, …
There are a number of approaches that can be used, such as: Internet Explorer automation, MSXML2.XMLHTTP, …
As usual, the information on how to do this is sparse, and sometimes hard to find, especially when you don’t even know the proper terms to search for in the first place. Below are a few links to help you get on your way.

Ever needed to extract a list of files within a folder/directory? Ever needed to iterate through the files within a given folder/ directory?

I was asked in a support forum how to convert an Excel *.xls, *.xlsx file to *.csv format. I didn’t readily have an answer so I created a custom function to help the user out. So here are the fruits on my labors should it help someone else out. What is also nice about the way it is written, is that it will run in any MS Office application (MS Access, MS Word, MS PowerPoint, MS Outlook, …) without requiring any modifications (copy & paste, that’s it)!

End Function |
Now this could be further improved by extending the error handling further to trap specific errors such as 1004 – file not found, etc… but it definitely illustrates the basic principle in using late binding to utilize Excel to open the file and convert it to *.csv format.
I hope this helps.

It can often come handy to be able to quick determine if a Folder/Directory exists or not. Below is a function I created some time ago to do exactly that.

Function FolderExist(sFolder As String) As Boolean

If sFolder = vbNullString Then GoTo Error_Handler_Exit
If Dir(sFolder, vbDirectory) <> vbNullString Then
FolderExist = True
End If
Error_Handler_Exit:
On Error Resume Next
Exit Function
Error_Handler:
If Err.Number <> 52 Then
MsgBox "The following error has occured" & vbCrLf & vbCrLf & _

"Error Source: FolderExist" & vbCrLf & _

One of he most common methods for creating directories/folders in VBA is to use the MkDir statement. For instance:
One quickly learns the limitations of this technique the minute they have to create a directory structure with multiple sub-folders. MkDir can only create 1 directory at a time and cannot create a sub-directory. Hence, assuming that C:\databases does not already exist, the following would not work and will return an error!
MkDir "C:\databases\msaccess\" |
If you absolutely want to create such a structure using the MkDir statement you’d have to do so using 2 MkDir statement. For instance:
MkDir "C:\databases\"
MkDir "C:\databases\msaccess\" |
Now if you need to merely create 1 or 2 sub-folder MkDir may still be acceptable, but there are cases where this is simply impracticle and another solution needs to be found. Well, I found two possible solutions!
One possible approach can be found at Creating Nested Directories.
The second I found searching through the net and I no longer know the original source of the code (if someone knows e-mail me and I will put credit where it is due). It is a simple API which can create multiple directories in 1 call.
Private Declare Function MakeSureDirectoryPathExists Lib "imagehlp.dll" (ByVal lpPath As String) As Long
Public Sub MakeFullDir(strPath As String)
If Right(strPath, 1) <> "\" Then strPath = strPath & "\" 'Optional depending upon intent
MakeSureDirectoryPathExists strPath
End Sub |
Another possible solution, if someone wanted to tinker a little would be to merely parse the path into it’s directories and the using the DIR statement evaluate and create the directories where need be. Shouldn’t be that hard, but I haven’t taken the time to do this (maybe one day I will and will update this post then).
Okay, so it bothered me and I had to quickly put something together to stop my brain from churning! Below is what I pieced together rapidly. It is missing proper variable definitions (DIM statements) and error handling, but from my very brief testing, it does appear to work and doesn’t require any APIs! 100% VBA.
Public Sub MyMkDir(sPath As String)
Dim iStart As Integer
Dim aDirs As Variant
Dim sCurDir As String
Dim i As Integer
If sPath <> "" Then
aDirs = Split(sPath, "\")
If Left(sPath, 2) = "\\" Then
iStart = 3
Else
iStart = 1
End If
sCurDir = Left(sPath, InStr(iStart, sPath, "\"))
For i = iStart To UBound(aDirs)
sCurDir = sCurDir & aDirs(i) & "\"
If Dir(sCurDir, vbDirectory) = vbNullString Then
MkDir sCurDir
End If
Next i
End If
End Sub |
As you can see, there are numerous way to handles this issue. Hopefully this helped answer a question for a few of you out there!

I ran into a particular problem with an associate of mine not too long ago and thaught I’d share the problem & solution with everyone. He had been given an .accdb database that evidently came from an mdb originally as it contained a custom command bar. The problem being that 2007/2010 support such command bars by simply placing them in the Add-Ins tab. However, this issue lies with the fact that 2007/2010 no longer offer the general user/developer a method to edit such command bars as they are considered to be deprecated. My associate wanted to merely delete this command bar and replace it with a proper custom Ribbon Tab. So how do you delete a command bar? Good question! In 2007/2010 the only solution is to use VBA. The actual code to delete a command bar is very simple, as shown below.
Application.CommandBars("CommandBarName").Delete |
Sound simple you say. Sadly, no! Once again because MS has decided no longer provide any tools to work with these ‘elements’, you cannot identify the name of the Add-Ins toolbars. if you can’t identify it, you can’t delete it! So what to do? Well, I came up with another simple solution and created a procedure that merely listed all the command bars within the current database. then we could go through the list and identify the one that we needed to delete. Below are two slightly different procedures. The first one is a more general version which merely lists all of the command bars within the database, the second is a slightly more refined version that only lists open command bars. Since the Add-Ins Tab was active, the 2nd procedure was a better option in our case and thus reduce the list we had to sift through (our list went from 202 items to 4 – from there it was easy to determine which one we needed to eliminate).

So as you can see, it is still possible to manipulate command bars in MS Access 2007/2010, but it can now only be done through the use of VBA code!
Thanks to a post by Albert Kallal, a fellow MVP, we also found out that it could be necessary to execute the following
CurrentDb.Properties.Delete("StartUpMenuBar") |
and in our case it was required as even after deleting the commandbar in question we were still receiving the error message
… can’t find the object ‘MyCommandBarName.’
If ‘MyCommandBarName’ is a new macro or macro group, make sure you have saved it and that you have type its name correctly
