Using IF statments and Now() together - if-statement

I am trying to make a simple logic on google sheets but there is some error. I want to 3 check boxes and when they are marked current time is saved.
so far i am using these three statements
=if($B$2=TRUE(),NOW(),0)
=if($B$3=TRUE(),NOW(),0)
=if($B$4=TRUE(),NOW(),0)
b2, b3 and b4 are cells addresses for check boxes. The problem i am facing is when i check B2 it gives me the current time. But when i check B3 it gives me current time and also changes the time of B2 similarly when i check b3 it changes the time for all three to the current time.
Why is this happening and what could be the probable solution.
Thankyou in advance

You cannot get a permanent timestamp with a spreadsheet formula, even with a named function or an Apps Script custom function, because formula results refreshed from time to time. When the formula gets recalculated, the original timestamp is lost.
The easiest way to insert the current date in a cell is to press Control + ; or ⌘;. See the keyboard shortcuts help page.
You can also use an onEdit(e) script to create permanent timestamps. Search this forum for [google-apps-script] timestamp to find many examples.

How to automatically feed a cell value from a range of values, based on its matching condition with other cell value

I'm making a time-spending tracker based on the work I do every hour of the day.
Now, suppose I have 28 types of work listed in my tracker (which I also have to increase from time to time), and I have about 8 significance values that I have decided to relate to these 28 types of work, predefined.
I want that, as soon as I enter a type of work in cell 1 - I want the adjacent cell 2 to get automatically populated with a significance value (from a range of 8 values) that is pre-definitely set by me.
Every time I input a new or old occurrence of a type of work, the adjacent cell should automatically get matched with its relevant significance value & automatically get populated in real-time.
I know how to do it using IF, IFS, and IF_OR conditions, but I feel that based on the ever-expanding types of work & significance values, the above formulas will be very big, complicated, and repetitive in the future. I feel there's a more efficient way to achieve it. Also, I don't want it to be selected from a drop-down list.
Guys, please help me out with the most efficient way to handle this. TUIA :)
Also, I've added a snapshot and a sample sheet describing the problem.
Sample sheet
XLOOKUP() may work. Try-
=XLOOKUP(D2,A2:A,B2:B)
Or FILTER() function like-
=FILTER(B2:B,A2:A=D2)
You can use this formula for a whole column:
=INDEX(IFERROR(VLOOKUP(C14:C,A2:B9,2,0)))
Adapt the ranges to your actual tables in order to include in the second argument all the potential values and their significances
This is the formula, that worked for me (for anybody's reference):
I created another reference sheet, stating the types of work & their significance. From that sheet, I'm using either vlookup, filter, xlookup.Using gforms for inputting my data.
=ARRAYFORMULA(IFS(ROW(D:D)=1,"Significance",A:A="","",TRUE,VLOOKUP(D:D,Reference!$A:$B,2,0)))

Getting #ERROR! Message when combining valid formulas

I am trying to setup a formula in one line that will calculate the proper date that a contract can be cancelled based on the Texas Addendum for Property Subject to Mandatory Owner's Association. Depending on 3 possible selections, Section A1, Section A2, or Section A3, the calculations for the possible termination of a contract vary.
My formula's work on their own, but not when combined into one long if statement.
Here are the 3 formula's. All work properly on their own.
=if(E12="A1",if(B17="",B20,B17+3),)
=if(E12="A2",if(B17="","",B17+3),)
=if(E12="A3",if(B17="",B20,""),)
However, when combined into one statement I get an #ERROR!.
I've tried multiple ways to write the formula but all get the same #ERROR!.
=if((E12="A2",if(B17="","",B17+3)),if(e12="A1",if(B17="",B20,B17+3)),if(E12="A3",if(B17="",B20,"")),)
=if((E12="A2",if(B17="","",B17+3)),if(e12="A1",if(B17="",B20,B17+3)),if(E12="A3",if(B17="",B20,""),))
=if((E12="A2",if(B17="","",B17+3),),if(e12="A1",if(B17="",B20,B17+3),),if(E12="A3",if(B17="",B20,""),))
Currently this is working as is as I have a final calculation in the necessary cell that takes the one value greater than zero.
=if(D31>0,D31,if(D32>0,D32,if(D33>0,D33)))
But it's not as clean as I'd like to have it. I'd prefer to have this as one single line calculation instead of in 4 different cells.
proper nesting is done like this:
=IF(E12="A1", IF(B17="", B20, B17+3),
IF(E12="A2", IF(B17="",, B17+3),
IF(E12="A3", IF(B17="", B20, ), )))

Google Sheets: Sum a Value Range Within a Specified Time Frame

I'm trying to sum a range of values, within a given time frame. The time frame could be x hours, or y days, etc. An example:
So for each row, I need to sum the last hours or days as specified in cells C2:E2, which are numeric (just added formatting to show the text). Note that the datetime values do not follow any interval pattern, but are always sequential.
Although I've tried searching SO, and via Google, I haven't been able to find a way to do this.
Any suggestions would be very welcome.
[Edit]
I've added to a link to an example sheet of what I'm trying to do... pls just ask if I can add any further info!
Test Sum By Time
try:
=SUMIFS(B3:B, A3:A, ">="&NOW()-1)
=SUMIFS(B3:B, A3:A, ">="&NOW()-7)
In Google sheets, use the =TODAY() code to for today's date and put this in another cell. You could always create a new sheet (which we will call sheet3) which you hide afterwards. Let's imagine you put this in cell A1.
You can use the =IMPORTRANGE("the google sheets website link", "Sheet Name!A3:A31" to insert the values. Let's imagine you import this into B3:B31. In C3, you put =IF(REGEXMATCH(B3, A1), 1, 0).
You continue this in each cell from B4:B31, each time changing "B3" to the current row number. Then we can use the =SUM(C3:C31) code to count how many meet this condition. Let's imagine you put this in A2.
Now back to the original sheet. Use `=IMPORTRANGE("the google sheets website link", "sheet3!A2" in the cell C3.
For the other 2, I don't know, sorry!

Stream Analytics Output

I have a project that uses an event hub to receive data, this is sent every second, the data is received by a website using SignalR, this is all working fine, i have been storing the data in to blob storage via a Stream Analytics Job, but this is really slow to access, and with the amount of data i am receiving off just 6 devices, it will get even slower as this increases, i need to access the data to display historical data on via graphs on the website, and then this is topped up with the live data coming in.
I don't really need to store the data every second, so thought about only storing it every 30 seconds instead, but into a SQL DB, what i am trying to do, is still receive the data every second but only store it every 30, i have tried a tumbling window, but from what i can see, this just dumps everything every 30 seconds instead of the single entries.
am i miss understanding the Tumbling, Sliding and Hopping windows, i am guessing i cannot use them in this way ? if that is the case, i am guessing the only way to do it, would be to have the output db as an input, so i can cross reference the timestamp with the current time ?
unless anyone has any other ideas ? any help would be appreciated.
Thanks
am i miss understanding the Tumbling, Sliding and Hopping windows
You are correct that this will put all events within the Tumbling/Sliding/Hopping window together. However, this is only valid within a group by case, which requires a aggregate function over this group.
There is a aggregate function Collect() which will create an array of the events within a group.
I think this should be possible when you group every event within a 30 second tumbling window using Collect(), then in the next step, CROSS APPLY each record, which should output all received events within the 30 seconds.
With Grouper AS (
SELECT Collect() AS records
FROM Input TIMESTAMP BY time
GROUP BY TumblingWindow(second, 30)
)
SELECT
record.ArrayValue.FieldA AS FieldA,
record.ArrayValue.FieldB AS FieldB
INTO Output
FROM Grouper
CROSS APPLY GetArrayElements(Grouper.records) AS record
If you are trying to aggregate 30 entries into one summary row every 30 seconds then a tumbling window is a good choice. Something like the following should work:
SELECT System.TimeStamp AS OutTime, TollId, COUNT(*) as cnt, sum(TollCharge) as TollCharge
FROM Input TIMESTAMP BY EntryTime
GROUP BY TollId, TumblingWindow(second, 30)
Thanks for the response, I have been speaking to my contact at Microsoft and he suggested something similar, I had also found something like that in various examples online. what I actually want to do, is only update the database with the data every 30 seconds. so I will receive the event, store it, and I will not store it again until 30 seconds have passed. I am not sure how I can do it with and ASA job to be honest, as I need to have a record of the last time it was updated, I actually have a connection to the event hub from my web site, so in the receiver, I am going to perform a simple check, and then store the data from there.

How to iterate over all the page breaks in an Excel 2003 worksheet via COM

I've been trying to retrieve the locations of all the page breaks on a given Excel 2003 worksheet over COM. Here's an example of the kind of thing I'm trying to do:
Excel::HPageBreaksPtr pHPageBreaks = pSheet->GetHPageBreaks();
long count = pHPageBreaks->Count;
for (long i=0; i < count; ++i)
{
Excel::HPageBreakPtr pHPageBreak = pHPageBreaks->GetItem(i+1);
Excel::RangePtr pLocation = pHPageBreak->GetLocation();
printf("Page break at row %d\n", pLocation->Row);
pLocation.Release();
pHPageBreak.Release();
}
pHPageBreaks.Release();
I expect this to print out the row numbers of each of the horizontal page breaks in pSheet. The problem I'm having is that although count correctly indicates the number of page breaks in the worksheet, I can only ever seem to retrieve the first one. On the second run through the loop, calling pHPageBreaks->GetItem(i) throws an exception, with error number 0x8002000b, "invalid index".
Attempting to use pHPageBreaks->Get_NewEnum() to get an enumerator to iterate over the collection also fails with the same error, immediately on the call to Get_NewEnum().
I've looked around for a solution, and the closest thing I've found so far is http://support.microsoft.com/kb/210663/en-us. I have tried activating various cells beyond the page breaks, including the cells just beyond the range to be printed, as well as the lower-right cell (IV65536), but it didn't help.
If somebody can tell me how to get Excel to return the locations of all of the page breaks in a sheet, that would be awesome!
Thank you.
#Joel: Yes, I have tried displaying the user interface, and then setting ScreenUpdating to true - it produced the same results. Also, I have since tried combinations of setting pSheet->PrintArea to the entire worksheet and/or calling pSheet->ResetAllPageBreaks() before my call to get the HPageBreaks collection, which didn't help either.
#Joel: I've used pSheet->UsedRange to determine the row to scroll past, and Excel does scroll past all the horizontal breaks, but I'm still having the same issue when I try to access the second one. Unfortunately, switching to Excel 2007 did not help either.
Experimenting with Excel 2007 from Visual Basic, I discovered that the page break isn't known unless it has been displayed on the screen at least once.
The best workaround I could find was to page down, from the top of the sheet to the last row containing data. Then you can enumerate all the page breaks.
Here's the VBA code... let me know if you have any problem converting this to COM:
Range("A1").Select
numRows = Range("A1").End(xlDown).Row
While ActiveWindow.ScrollRow < numRows
ActiveWindow.LargeScroll Down:=1
Wend
For Each x In ActiveSheet.HPageBreaks
Debug.Print x.Location.Row
Next
This code made one simplifying assumption:
I used the .End(xlDown) method to figure out how far the data goes... this assumes that you have continuous data from A1 down to the bottom of the sheet. If you don't, you need to use some other method to figure out how far to keep scrolling.
Did you set ScreenUpdating to True, as mentioned in the KB article?
You may want to actually toggle it to True to force a screen repaint. It sounds like the calculation of page breaks is a side-effect of actually rendering the page, rather than something Excel does on demand, so you have to trigger a page rendering on the screen.
