I am creating very simple SQR report with page numbers being printed on every page. It works fine with less number of pages. But when I tried to print 1000000 pages, it stopped printing last page number. Instead it prints Page 1 of *****.
Also I am not able to find any global variable which holds last page number; just like we have #page-count for current page.
Following code is being used to print page numbers.
page-number(1,37) 'Page '
last-page () ' of ' '.' ! "Page 12 of 25."
There is one workaround, create another file before it prints Asterisks. starting page number with 1 for another file.

I have 8 images in a directory.
the path is /blabla.com/img.
I need to access this path and choose 3 out of 8 randomly and display those.
If 3 pics are the same, it should echo "yeeey".
Otherwise, "neeey" and record these responses in a text file.
I am not going to do your homework for you!
However I can give you some insight:
store your 8 file names in an array
call $RANDOM % 8 3 times and store the value in 3 index variables
use the 3 index variables to extract your 3 files
use sha256sum, sha512sum or md5sum to compute the signature of your images and store the result in 3 variables
compare the values of the 3 variables if they are the same echo "yeeey" else echo "neeey"
if on top of that you want to display the picture as written in your post you could call eog or other similar tool with the finename as parameter and of course in background, with a & at the end of the command call.
Good luck with your assignment and let me know if you need help!
let's array an array of distinct elements (for example 8):
array=({A..H})
(1) use RANDOM special variable modulo the number of elements to get a random number between 0 and number-1 inclusive
number=$((RANDOM%${#array[#]}))
the first random element is
first=${array[number]}
remove the element from array and reassign the array to reindex without gap (declare -p array to see)
unset array[number]
array=("${array[#]}")
restart from (1)
I need to provide a listing of a website's pages. The only thing to change per line is the page number at the end of the line. So for example, I need to take:
mywebsite.com/things/stuff/?q=content&page=1
And from that generate a sequential listing of pages:
mywebsite.com/things/stuff/?q=content&page=1
mywebsite.com/things/stuff/?q=content&page=2
mywebsite.com/things/stuff/?q=content&page=3
I need to list all pages between 1 - 120.
I have been using bash but any shell that gets the job done is fine. I don't have any code to show because I simply just don't know how to begin. It sounds simple enough but so far I'm completely at a loss as to how I can accomplish this.
With GNU bash 4:
printf '%s\n' 'mywebsite.com/things/stuff/?q=content&page='{1..120}
You can simply use:
for i in $(seq 120); do echo 'mywebsite.com/things/stuff/?q=content&page='"$i"; done > list.txt
I have a text note file that I need to break up into 200 character lines. But, I need to keep the first 50 characters from the original line as it allows the note file to import into clients system. I have been playing with bash and found fold -50 will fold it at 50 characters and then fold -200 will fold it at 200 characters. Is there a way to take the file and save first 50 but fold at 200 until it reaches the end of the row?
Here is a test of the test file.
PTSTISN1P AA1511200095PPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPP201506301200FPaaRPTSTISNB PtstisPtstisPtstisOld Patients->Ins Ph #: '(888)888-8888' updated the phone number and called INS to let them know about the number changing. Also, updated number with hospital for Patients contacts.
I need it to save this part for each row it creates
PTSTISN1P AA1511200095PPPPPPPPPPPPPPPPPPPPPPPPPPP
It is not saving all the P's as the first row has a few extra plus a date and time plus user that creates note and the second and remaining rows that info is not needed. Also, even better would be where PTSTISN1P change the 1 into 2 as that is needed for the second, third, etc. lines the 1 is for 1 second and 2 for all remaining lines.
I tried something like:
fold -50 note.txt > newnote.txt && fold -150 note.txt > newnote.txt
but that is not working like I thought it would.
I am slimming down my databases, eliminating duplicate reports where I can and creating better code. I have one database that involves our welders and foremen. In this code, I can print a report for an individual foreman, which sends the string "strActive" through openargs The report looks at strActive and on the OpenForm action, sets the filter for active, inactive, or all welders, based on the string value passed through.
It works perfectly for the single page at a time code. There, the user chooses a foreman from a list or enters the foreman's clock number. The query the report is based on uses the global string "ForemanCLK" to only get results for that welder.
Formerly, I had three reports; one for all welders, one for active welders, and one for inactive welders.
Previously, I would set a variable based on strActive and open the appropriate report using another variable in the code in place of the report name. The loop worked fine and opened the report 39 times, each time with a new foreman name and data.
I'm baffled as to why opening the report now, with an openarg, doesn't work. I only get the first foreman name, 39 times. I've verified that I get the foremanCLK variable of the different foremen by commenting out the docmd line and debug.print(ing) the various values needed by the form. The report simply doesn't load it correctly.
Set rec = CurrentDb.OpenRecordset(sql)
rec.MoveFirst
For ctr = 0 To rec.RecordCount - 1
ForemanCLK = rec(0).Value
DoCmd.OpenReport "rptForeman", acViewNormal, , , , strActive
'DoCmd.OpenReport "rptForeman", acViewNormal
rec.MoveNext
Next
The above code gets me many copies of the same foreman's report filtered by strActive
For ctr = 0 To rec.RecordCount - 1
ForemanCLK = rec(0).Value
'DoCmd.OpenReport "rptForeman", acViewNormal, , , , strActive
DoCmd.OpenReport "rptForeman", acViewNormal
rec.MoveNext
But this gets me all the different foremen, except it is not filtered.
I've tried passing in a Where clause.
acViewNormal, ,"[active]=" & True
and
acViewNormal, ,"[active]=" & False
and
acViewNormal, ,"[active]=" & True & " OR [active]=" & False
I did the same verification with the single report, and it filters correctly, but in the loop, it does not filter at all. It does, however give me the different foremen.
The big question here is...
WHY? Does access not have enough time between reports to close it and therefore it doesn't perform the operations on the open event?
Any other ideas?
You must close the report explicitly inside your loop: DoCmd.Close acReport, "rptForeman". If OpenReport is called a second time on an already-open report, the object gets the focus in access, but it doesn't re-run the Open event.
Okay, I must hang my head in shame.
I error checked the hell out of that code above using every variable except strActive.
When I added that to my debug.print line, it came up with nothing. How can that be!?!!??
I simply forgot to set that at the beginning of the sub, like I did with the other action that opens a single report. strActive is a global variable, but was not set at any other point in the code up until this piece.
Once this was added to the beginning of the sub, all worked fine.
I'm creating a report in vfp. The report contains grouping. In the end of each group, i draw a line. Each row in the detail band doesn't contain any line, only at the end of each group. The problem is when the group expand to the next page, in the previous page i want to draw a line at the bottom. Like this :
(page 1)
group A
name, etc
x1,etc
x2,etc
???how do I add line here?
(page 2)
group A
name,etc
x3,etc
x4,etc
group B
name,etc
y1,etc
y2,etc
I've tried to place the line in the page footer band, but the last line of the report doesn't have exact position, so it doesn't look nice.
Hope I described the situation clear enough. Thank You for taking the time to help me.
Without some significant smoke-and-mirrors trickery: running the report twice, once hidden and track where the breaks are via function calls in the report, and then again for production, its not EASILY done.
The only thing I could suggest is putting a line at the TOP of a PAGE FOOTER which prints on EVERY page. How long have you been working with VFP. Depending, I MIGHT be able to guide you through it.
Ok, here are the steps I would take. This is under the assumption that you are pre-querying the results for your report and ordering them by some means into a temporary report cursor. You need to add 2 columns to your query as place-holders and be sure your do your cursor as " INTO CURSOR READWRITE " as we will be writing to this from within the report... that is the trick.
Next, modify your report. Go to the detail band and put a single line at the bottom of it. Adjust as needed if you need a few pixels under the last detail element. Double click the line and get to the tab where it allows you to put in a "Print When" condition for the line. Enter one of the new column names called "ShowLine" (but without the quotes).
Now, the "hook" for smoke and mirrors. Create another textbox field output in the report detail. It can be as small as 2 pixels wide and never actually prints anything. It can be put at the beginning or end of the report detail, no matter, just as long as its in the detail band. Double click it to bring up what it will print. In the expression, enter the following... WhatPageAmIOn( _PageNo )
This will actually call a function we'll add to your program which writes back to your report cursor... I'll hit that next.
Now, the code. The following is a sample snippet of code I've written to query the data for the report, have the extra columns, and put into a READWRITE cursor. From that, I run the report but to NOCONSOLE so it doesn't actually visually do anything, just runs in the background. It then cycles through and looks for the break between each page and goes backward 1 record from the break and stamps that record as "ShowLine" = .T... Then run the report again as normal and you have your one line appearing in the detail band regardless of a data group, but always the last data line at the end of each page.
Here's the code
*/ Query your data, order by whatever,
*/ but tack on the two extra fields and make it READWRITE
select;
YourData,;
AnotherField,;
MoreData,;
.f. as ShowLine,;
00000 as WhatPage;
FROM ;
YourData;
ORDER BY ;
WhateverForYourReport
INTO ;
CURSOR C_RptData READWRITE
*/ Pre-run the report NOCONSOLE so your windows don't get messed up / scrolled
REPORT FORM YourReport NOCONSOLE
*/ now, go back to the cursor that your report ran with
SELECT C_RptData
*/ set a variable for the first page you are looking to find a break for.
*/ in this case, the first detail that APPEARED on page 2.
lnLastPage = 2
*/ Start at top of the report cursor file and keep going until we reach
*/ the end of file where the LOCATE can no longer find "Pages".
GO TOP
DO WHILE NOT EOF()
*/ find the first record on ex: Page 2
LOCATE FOR WhatPage = lnLastPage
*/ Did we find one?
IF FOUND()
*/ Yes, go backwards 1 record
SKIP -1
*/ This is the last detail that appeared on the page before it (ie: pg 1)
*/ Mark this line as ok to "ShowLine" the next time the report is run.
replace ShowLine WITH .T.
*/ Now, advance the page counter to look for the NEXT page break...
*/ ex: between page 2&3, 3&4, 4&5, etc...
lnLastPage = lnLastPage +1
ENDIF
ENDDO
*/ Run your final version of the report
REPORT FORM YourReport Preview (or print)
RETURN
Here's the only hook below to track/update the page associated with the detail. I don't know if you have a main "SET PROCEDURE TO" file, or just a bunch of free .PRG files all in your project, or even if your reporting is done from within a PRG file itself. however, all you need is this function to be included in any of those locations. For simplest test, I would just create it as a stand-alone .prg file (if you are NOT using SET PROCEDURE, or doing your report within a PRG file and not from within a class method/event).
FUNCTION WhatPageAmIOn
LPARAMETERS lnPage
replace whatPage WITH lnPage
RETURN ""
As in the original description, the report is going to include a field in the detail band based on a function "WhatPageamIOn" and passes the parameter of _PageNo which is the internal VFP variable that keeps track of the current report page that is typically used in report header / footers. So, as each detail is getting processed, we are "STAMPING" the detail data with whatever the page is. We return an empty string "" so nothing actually gets printed, yet we've hooked what we needed. From this, the loop finding the first record at the beginning of every page (starting at page 2), and skipping backwards to the last entry for the prior page and we're done.
Good luck.
