[VBA] Something like COUNTIFS for Excel 2003

Well, there you go. A colleague sends you a copy of an Excel file and needs a nice formula. So I do the nice formula. Then I try to save the sheet back into the same form in which it arrived:

Clang!

Seems that Excel 2003 doesn't have the nice little COUNTIFS function that I have in my Excel 2007. What to do, what to do, what to do ...

Well, it'd be nice to install Office 07, but in the interim, how about a bit of VBA?

We'll call it RANGEDCOUNT, and it will accept a range of data, and a string being the criteria. The criteria can be
  1. a single value preceded by an operation (>, >=, =, <=, <, #), or

  2. a range of values, the upper and lower bounds separated by a dash.

Right, that's all the declarations over with. Now to check whether we have a range specification or not and what to do if it's not. Notice the 'Instr(2' which checks for an equals sign after the first character, as we're checking to see if we have '>=' or '<=' and don't want to fail on a bare equals
The else fires if we do in fact have a range setting and handles that appropriately.
Next, step through the data and for each element, apply the logic for either a ranged count or an operator count.
Okay, iCount should have the result, so put it in RANGEDCOUNT and end.
Not bad for 15 to 20 minutes work, and would've been faster if I'd remembered how to get data out of Ranges. Now my colleague is happier and I've had a chance to do some something interesting. Granted, it's not particularly fault tolerant, but it's enough for now. © Bruce M. Axtens, 2010

[Visual BASIC 6] BOOST (v2)

I revisited BOOST this week. A friend had pointed out to me some time back that /P: and /L: were a bit of a pain when one wanted to speed something up quickly, or kill it quickly. So this version changes the command line handling.

This version also demonstrates how to kill a process. In fact it kills every process of the same name. I wish I'd had this a couple of years ago when I was doing stuff with Excel -- I'd end up with multiple Excel sessions which I would then have to kill off one-by-one through the Task Manager. (I eventually ended up installing Cygwin so that I could script the process.)

If you remember the original VBScript of BOOST and the first VB6 version, you'll see some similarities.

I've given up on using
setsubsys in favour of using VBAdvance (which is now freeware) to handle the compile-to-console-app process. I'm still compressing the app using UPX.

First a few constants and the declarations, found on
vb.mvps.org, for doing console I/O.



Next, a few supporting functions. First off the rank, is an invocation syntax display. Notice that priority can now be specified either by a number (0 to kill, 1-6 for low to realtime) or by name (kill, low, belownormal, normal, abovenormal, high, realtime).



Second, the command line parser. This splits on space and tab and is based on code found at
microsoft.public.vb.winapi



Third, the two routines which wrap the WMI functions to set priority and to kill process. The latter was found at
tek-tips. If I remember correctly, the places in each routine where it says
sComputer = "."
could, in fact, have some other computer's name. If you had sufficient privilege you could be tweaking or killing a process on someone else's machine.



Finally, the Main subroutine. Notice the additions to the priorities collection. Note also the change in the way the command line is handled.

Because there's no .Exists method on Collections, the .Item call is wrapped in an 'On Error' so that a non-existent item situation is caught appropriately.



What's next with this thing? I suppose one could explore the possibility of influencing the lives of applications on other computers:
BOOST Skype.exe kill /C:GUEST_01
There's also the fact that the commandline parser doesn't properly handle double-quoted names. If an .exe had a space it its name, you wouldn't be able use BOOST on it.

Finally, here's a short batch file (killall.bat) I use for killing applications en masse. It was originally designed to get around the 'typing the /P and /L' issue, but I'm so used to using it now ...



An example invocation:
killall excel.exe outlook.exe

[VBScript] When did I log on/off?

The Australian federal government has brought in new laws which seem to require a return to the old days of clocking in at the beginning of the working day and clocking out at the end. As a contractor I don't think I'm going to notice a big difference ... if I want to get paid for the hours I work, then I fill out my timesheet appropriately.

If you aren't in the habit of keeping this kind of information, don't worry too much: Windows keeps a track of your login and logout in one of its Event Logs. Getting that information is fairly easy, if you know what you're looking for. Otherwise its like the proverbial needle in the haystack.

The script outputs into an Excel spreadsheet, the date of each logon in a separate column containing time of logon and logoff. Please note that the script was designed to query someone else's machine, and will likely need modification if you are trying to get your own data out of your own event log.

Here's the code.

As is often the case in my scripts, the preamble loads external code libraries. The former is a the standard library and the latter (see the end of the posting) a symbol table class, based on the Scripting.Dictionary object.
Next comes code to split up the event log's timestamp, followed by the routine to store logon date and logon and logoff times into spreadsheet cells.
Next comes the variable declarations. In retrospect the variables sComputer and sUser could have been Const rather than Dim. For that matter they could have been taken from the command line. Note the double backslash in the uUser variable: this is needed for where it occurs in the WMI call.
This is the core of the script: pointing WMI at sComputer and executing an SQL query against Win32_NTLogEvent. It asks for everything from the 'Security' Logfile where the EventCode matches a logon or a logoff and where the User matches sUser.
Then the script starts to do things with the list of events now stored in cEvents. First a Dictionary is loaded with logons as (zero, comma, TimeSplit of datestamp) and logoffs as (one, comma, TimeSplit of datestamp). The reason for this is that there may be more than one logon and logoff event for a given user during a working day. By storing the logon and logoff times in this way, the first "0" reference can be assumed to be the first logon off the day, and the last "1" can be assumed to be the last logoff of the day.
From the Dictionary wrapper class the keys are extracted. A check is put in here to make sure that there are records to be reported.
Next comes the Excel interactions. The ExcelStart and ExcelNewSheet macros are listed at the bottom of this posting.
What follows is the guts of the Excel reporting. Despite the possibility of incorrect recording, the assumption is that the report will contain the first logon and the last logoff. If a logon occurs after the last logoff, it is discarded. The script is unable to cope with the situation where someone logs on today and logs off tomorrow.

Note that a check is made not to report more dates than MAX_INSTANCE, a limit that has not yet been encountered. AMax and AMin are listed at the bottom of the posting.
Excel is left running with the results of the report. It's up to the user to save it, print it or whatever. To finish, the macros ExcelStart, ExcelNewSheet, AMax and AMin, and the ClassSymTab class as promised.

[VBScript and Excel] Relative/Absolute references

Again at Automate Excel In Vbscript... ( Vbscript ), Pentium10 wrote
I have a script which fills cells with exce.range.value function, but I have columns more than A-Z, how can I handle AA,AB, AC... columns???

Here is the script what I have:
excel.Range(chr(65+i) + str(excelrow), chr(65+i) + _
 str(excelrow)).value = lstOrder.cell(i,1)
And I wrote:

Re: I have a script which fills cells with ...

That does me, but for you I'd suggest adding a few more items to the Split(). After Z put in ",AA,AB,AC," etc until you have what you need. Then code your references in terms of numeric column and a row and let the function generate a meaningful address.

For example:
(iCount in this case is the number of rows in an array I was committing to the spreadsheet.)

[VBScript and Excel] Moving a sheet to the end of the list

Here's how to put the first sheet in a new spreadsheet at the end. This is a copy of a recent submission of mine at Automate Excel In Vbscript... ( Vbscript ) Note the comma after the space that is after the .Move. I'm specfying the "after" clause rather than the "before" and saying to move the sheet to after the last.

BTW, one of the best ways of finding out syntax is to record a macro and adapt the resulting code.
