Code: Accessing Windows Clipboard
Several years ago, I found some code to access the Win32 functions for the Windows Clipboard. I don't remember where I found it, who wrote it or if it was VB code that I modified or already written for Lotusscript. I rewrote the the code as a class and put it in a script library called "Class.Win32.ClipBoard". The complete code is listed below. In my next blog entry I will describe how I am using this class for some very convenient functions.
Option Public
Option Declare
Declare Private Function GetClipboardData Lib "User32" (Byval wFormat As Long) As Long
Declare Private Function SetClipboardData Lib "user32" (Byval wFormat As Long, Byval hData As Long) As Long
Declare Private Function OpenClipboard Lib "User32" Alias "OpenClipboard" (Byval hwnd As Long) As Long
Declare Private Function CloseClipboard Lib "User32" Alias "CloseClipboard" () As Long
Declare Private Function GlobalLock Lib "kernel32" Alias "GlobalLock" (Byval hMem As Long) As Long
Declare Private Function GlobalUnlock Lib "kernel32" Alias "GlobalUnlock" (Byval hMem As Long) As Long
Declare Private Function GlobalAlloc Lib "kernel32" (Byval wFlags As Long, Byval dwBytes As Long) As Long
Declare Private Function GlobalFree Lib "kernel32" (Byval hMem As Long) As Long
Declare Private Function EmptyClipboard Lib "user32" () As Long
Declare Private Function lstrcpyLP2Str Lib "kernel32" Alias "lstrcpyA" (Byval lpString1 As String, _
Byval lpString2 As Long) As Long

Declare Private Sub MoveMemory Lib "kernel32" Alias "RtlMoveMemory" (Byval strDest As Any, _

14 Years Ago…
This Sunday it was 14 years ago I stepped onto an airplane in Stockholm, Sweden. In the morning hourse of January 1, 1998, my dad and my sister took me to the airport for my move to the US. I had married Angie back in August, and soon after that she told me she wanted to move back to the US. I applied for and got a resident visa (green card) and got a job with IDG in Boston. Initially we had planned to move to Seattle, but when I was offered the job in Boston I took that one instead.
Some 18 hours later I landed in Spokane, WA, where Angie met me. She had been staying with her mom, who lived in northern Idaho, while I got our appartment in Sweden packed up in 13 moving boxes (that is what I could afford to ship) and I got everything finished at my previous job at IDG in Sweden. My last task was to build an editorial system in Lotus Notes 4.6, that I built in 3 weeks. By the way, this system is still in use today, having survived several attempts to have it replaced with different other publishing systems.
After four days of driving cross-country from Idaho to Boston, we got an apartment and I started working as a full-time Lotus Notes developer on January 7.
Much have happened since. In 2000 we had our son Erik, in May 2002 we moved to Texas and I started working at Deep South as a Sr. Lotus Notes developer, in late summer of 2002 we moved into our first house, and then in July 2003 Angie and I separated and finally divorced aftyer 6 years of marriage.
It is interesting that I now have been working with Lotus Notes almost three times the time I was married, despite all the claims I have seen for many years that "Notes is Dead"…
As always, it will be exciting to see what the coming year brings me, both on a personal and professional level. Perhaps I will finally get the time to learn Xpages and/or Java?
Free Tool: Clean your NAB
As a follow-up to my previous tool that let you analyze the ACL of a database, I built another tool for my admin. For different reasons, we need to keep the mailbox of terminated users, sometimes for a shorter time but sometimes for long periods of time. As far as I understand it, if a traditional approach was used to remove a user from the system, the mail file would also be deleted. So the admin put the terminated user in the Deny Access group and change the ACL of the mailfile to include a manager, supervisor or replacement.
But because of this process, AdminP will not remove the terminated user from all the groups he/she is listed in. When you have hundreds of groups, many of them nested, this could be a real headache. So I was asked to build something simple that allows us to remove one or more specified users from all groups in the Domino Directory. Below is the result. Enjoy!
Update: I tweaked the code slightly, to avoid three separate calls to GetItemValue() and to make a line shorter. The modified code is in the end, where I update the deletelog list.
First I created a form with 3 fields:
‘SaveOptions’ has a default value of “0” (to prevent the form from being saved).
‘Users’ is a Names field, getting it’s values using the addresses dialog. The field is multi-value and using New Line as separator.
‘LogResult’ is a multi-value text field, again with New Line as separator.
Finally I added a button to the action bar to remove the user(s). The Lotusscript code is listed below. It is using my class for mail notifications that I blogged about in November, to send a confirmation to the user running the agent. This is useful for example when you need to log all data changes done to a system.
