Hi,
I programmed a lot of diffent entryforms in Epidata but now I sometimes
get a errormessage "window has no scrollbars", when I try to open a
rec-file in epidata entry by doubleclicking it in windows-explorer (Win
XP, SP3). This only happened with files, that use a big data-file for a
"comment legal" command in the chk-file (icd-code table with 14000 entries).
It seems to work, when I start epidata as a window (not maximized!) and
then open the rec-file. Or if I closed epidata entry before as a window
(not maximized) and then double click the rec-file in win-explorer.
If I close epidata maximized, the parameters in the epidata.ini-file are:
...
MainWinTop=-4
MainWinLeft=-4
MainWinBot=998
MainWinRight=1284
MainWinMax=1
...
(My monitor resolution is 1280x1024).
Is this a bug in Epidata entry? Does anybody had similar problems?
Greetings
Juergen
In the data entry module ts is advised that "All fields must fit within 999
lines of text" Does this apply to the qes as well as chk files?

Yesterday I was working on a questionnaire (over 300 variables) and at an
advanced stage, got this message "Access violation at address 0048AC7 in
module Epidata.exe. Read of address 00000000". I lost the whole work after
it will not allow me to save. I started anew but this time I backed up the
chk file at different stages of the developmeent of code (has a lot of skip
patterns and replace of values in all places which have been skipped). The
problem has appeared occurred agian and naturally have lost the code I was
building from this afternoon. Has this happened to anyone before and if so
how did you resolve it?
Thanks in advance
Martin

...or do in EpiData analysis:
select substr(cpr,5,4)="1940"
savedata "1940_only.rec" /replace
Hans
Do this:
define cprtxt __________ // string of length 10
define yrtxt __ // string of length 2
cprtxt = cpr
yrtxt = copy(cprtxt,5,2) // digits 5 & 6
select yrtxt = "40"
This can also be done in a single line, if you have no other use for the
year of birth:
select copy(cpr,5,6)="40"

In Denmark, we have the unique CPR number consisting of birthdate (ddmmyy) followed by 4 numbers. If I have to select a population born in fx 1940 from a larger epidata-fil, I consider to use the export facility, but then need an observation filter only selecting those born in 1940, which means those numbered 40, in position 5 and 6 in the 10 digit CPR variable. Do anybody have knowledge of a relevant syntax for that?

While it is nice that EpiData offers a maximum field length of 10, it might be wise (as example shows) not to exhaust the maximum if the data are to be analyzed in other software limiting the allowable length to 8.

Ziad,
First of all always backup your data before doing dangerous things such as
renaming variables.
That is simple. The first sugestion is to use EpiData entry tools menu...
there is something like rename fields(my menus are in portuguese) ... this
may help.
Another solution is to export two splits of the dataset to stata, one
containing the first the datebase but without the second datebase and a
second dataset with only the unique identifier and the second datebase.
Later, already with stata, you may rename the varibles and merge the two
datasets side by side with the unique identifier.

Hi!
I have had 2 date related vaiables called "datebase1" and "datebase2"
in EpiData. When exported them into STATA, they are showing as
"datebase" and "datebase" and both variables contain the same value
now which is not correct.
It might be due to the total number of characters for the variable
name, but my question is how can I fix it?
Best regards
ziad
I guess, you have to go back to your REC file, go to Tools | Rename fields, and change each of the two fields to names with 8 or fewer characters. While it is nice that EpiData offers a maximum field length of 10, it might be wise (as example shows) not to exhaust the maximum if the data are to be analyzed in other software limiting the allowable length to 8.
