What is the maximum length of variable names in the [ALIAS] section of HHP files?
I_AM_WONDERING_ABOUT_THE_MAXIMUM_LENGTH_OF_THIS_STRING_RIGHT_HERE=this-is-some-really-helpful-html-file.html
I have found a CHM/HHP specification right here:
https://www-user.tu-chemnitz.de/~heha/viewchm.php/hs/chmspec.chm/hhp.html
That page only talks about the length of the overall line, though (and not about the length of the variable name). Very specific question, I know. Still, someone may be able to point me somewhere.
As far as I know never asked before and I never heard about limitations. But I think this is because nobody used long variable names in this place so far.
The purpose of the two files e.g. alias.h and map.h is to ease the coordination between developer and help author. The mapping file links an ID to the map number - typically this can be easily created by the developer and passed to the help author. Then the help author creates an alias file linking the IDs to the topic names. That was the idea behind years (decades) ago by Ralph Walden (ex Microsoft).
Please note HTMLHelp is about 20 years old and these context ID strings inside a alias.h file were derived from WinHelp as a predecessor of HTMLHelp.
You'll find some further Information at Creating Context-Sensitive Help for Applications.
In general I'd recommend to use ID's with a fixed format because of the better legibility like shown below:

IDH_20000=Context-sensitive_example\contextID-20000.htm
IDH_20010=Context-sensitive_example\contextID-20010.htm
I'd recommend to use less than 1024 bytes per line.

I want to search all programs - within a package - that use the statement:
modify itab_xyz from wa_itab_xyz
Preferably, the string should be searched with wild cards like itab*
for a range of itab_(values) like itab_abc, itab_def, itab_ghi
etc..
How do i do this in SAP ABAP?
Below is a screenshot of all programs within a package one can search from.
One possibility would be to use program RS_ABAP_SOURCE_SCAN.
You can restrict the selection by package and you can also enter a specific string to search for in the code.
I use the transaction code_scanner (program is afx_code_scanner).
The biggest problem with this program and the RS_ABAP_SOURCE_SCAN provided above is that they won’t find everything. IMO the most important missing component to them is implicit enhancements. They can be very impactful to system functions, and if you are searching for an error message or hard coded value skipping them could mean not finding something critical.
At the time I looked (about 7 years ago), I was unable to find a delivered tool that would actually scan all the code in the system. I ended up enhancing the code_scanner to look for enhancements, WDA components, BSP code, and forms code.
I don’t know if the open source component above includes those. At first glance it doesn’t seem to, but I don’t have time to really dig into it.
You could use a tool from the Galileo-Open Source library. This program searches ABAP Source, OTR-Texts, Message and Textpools for static Text, wildcard patterns or regex patterns.
ABAP-Coding:
https://github.com/galileo-group/galileo-abap-lib/blob/master/%23gal%23devtools_find_text.prog.abap
Textpool:
https://github.com/galileo-group/galileo-abap-lib/blob/master/%23gal%23devtools_find_text.prog.xml
It refers to some additional classes from the library, so you either need to copy these as well or just use ABAPgit to get the whole library. You can also contact me, so I can send you a transport containing the library.
Additional information (October 1, 2020):
I created a version of the report that you can copy/paste to the ABAP editor. It is too long to include it in the response, but you can find it here.
Do not forget to copy the text elements / selection texts.
Required Text Elements:
-----------------------
B00 Scope
B01 Search pattern
H01 Type
H02 Name
H03 Key
H04 Match
Required Selection Texts:
-------------------------
P_CASE Case-sensitive
P_DEVC Package
P_LANGU Language
P_MESS Messages
P_OTR OTR Texts
P_PATT Pattern
P_REGEX Regular expression
P_SOURCE ABAP sources
P_TPOOL Textpools
P_WILDC Wildcard pattern
I would like to determine the Thousand Separator used while running a VBA Code on a target machine without resolving to calling system built-in functions such as (Separator = Application.ThousandsSeparator).
I am using the following simple code using 'Format':
ThousandSeparator = Mid(Format(1000, "#,#"), 2, 1)
The above seems to work fine, and would like to confirm if this is a safe method of doing it without resorting to system calls.
I would expect the result to be a single char string in the form of , or . or ' or a Space as applicable to the locale on the machine.
Please note that I want to only use a language statement such as Format or similar (no sys calls). Also this relates to Thousands Separator not Decimal Separator. This article Using VBA to detect which decimal sign the computer is using does not help or answer my question. Thanks
Thanks in advance.
The strict answer to whether it is safe to use Format to get the thousands separator is No.
E.g. on Windows, it is possible to enter up to three characters into the Thousands Separator field in the regional settings in the control panel.
Suppose you enter asd and click OK.
If you now call Format(1000, "#,#") it will give you 1a000. That is only the first letter of your thousands separator. You have failed to retrieve it correctly.
Reading the registry:
? CreateObject("WScript.Shell").RegRead("HKCU\Control Panel\International\sThousand")
you get back asd in full.
To be fair, the Excel international properties do not seem to be of much help either. Application.International(xlThousandsSeparator) in this situation will return the separator originally defined in your computer's locale, not the value you've overridden it to.
Having that said, the practical answer is Yes, because it would appear (and if you happen to know for sure, please post an answer here) that there is no culture with multi-char thousand separator (even in China where scary things like 1億2345万6789 or 1億2345萬6789 exist, they happen to be represented with just one UTF-16 character), and you probably are happy to ignore the people who decided to play with their locale settings in that fashion.
Here is the problem I want to solve:
Let's say I have a collection of 30 000 files (videos, images, sounds, etc...). And let's say I need to move/rename them a lot (including sub and parent folder). Not to mention those files will move from different OS (win, osx, linux(NAS) ) in a near future.
My problem stands when it comes to keep a link references to those files in my personal notes (evernote and blog mostly). Since URLs will broke all the time, I was thinking of adding a GUID/UUID in the file name (only for the file I need to refer to). this way, I could always do a search and find my file no matter where it is.
But GUID are quite a big string (36 characters if I've counted right). I don't need a world global uniqueness for my file. Just enough uniqueness to make a difference between maybe less than 10 000 reference (in my hole life ^^).
So I was thinking of using only the last 12 characters of a GUID string and add it to my file. Keeping the same string in my notes. And in case of collision, that would not be a problem because I know my files well and figuring out witch one is the right wouldn't be a problem.
Could this works?
Could I use an even smaller string ? (like the first 8 characters)
thx for your help.
Best.

Why does this ridiculously simple query on data.stackexchange.com return results that don't have [help/dont-ask] in the comment text? I feel like I'm missing something mind-numbingly obvious here.
select top 10 Id, PostId, Text
from comments
where text like '%[help/dont-ask]%'
Results I currently get:
Id PostId Text

1 35314 not sure why this is getting downvoted -- it is correct! Double check it in your compiler if you don't believe him!
2 35314 Yeah, I didn't believe it until I created a console app - but good lord! Why would they give you the rope to hang yourself! I hated that about VB.NET - the OrElse and AndAlso keywords!
4 35195 I don't see an accepted answer now, I wonder how that got unaccepted. Incidentally, I would have marked an accepted answer based on the answers available at the time. Also, accepted doesn't mean Best :)
9 47239 Jonathan: Wow! Thank you for all of that, you did an amazing amount of work!
10 45651 It will help if you give some details of which database you are using as techniques vary.
12 47428 One of the things that make a url user-friendly is 'discover-ability', meaning you can take a guess at url's simply from the address bar. http://i.love.pets.com/search/cats+dogs could easily lead to http://i.love.pets.com/search/pug+puppies etc
14 47481 I agree, both CodeRush and RefactorPro are visually impressive (most of which can be turned off BTW), but for navigating and refactoring Resharper is much better in my opinion of using both products.
15 47373 Just wanted to mention that this is an excellent solution if you consider the problem to be linear (i.e. treating `A1B2` as a single number). I still think the problem is multi-dimensional, but I guess we'll just have to wait for the author to clarify :)
16 47497 Indeed, the only way to do this is get the server to generate your CSS file which can be done in many ways depending on which language you are using. HttpHandlers are common in C#. You could use jQuery or the likes to add styling to every element with the class 'ourColur' and parametrise your JS
18 47513 This advice goes against the spirit of CSS, which is separation of content and presentation. You way requires changing HTML for presentation sake, and stating in content which elements have same color.
...none of which contains the magic link (or even the text dont-ask).
Because [] delimits a set of characters to find.
You need to escape them.
Or just use CHARINDEX as the search is unsargable anyway.
WHERE CHARINDEX('[help/dont-ask]', text) > 0
Interesting challenge; my client enters some product information in a SQL database. The product is a painting of a famous old Russian composer called Rachmaninoff. So that name is in the description field. Now, only a few of their customers searching for products know exactly how to spell this name, but most of the time it's misspelled. Besides misspelling there are also a lot of international customers who just write this name completely different like, Rachmaninow, Rahmaninov, Рахманінаў.
If i put any of these misspellings or translations in Google it (almost) always knows how to correct it and to redirect me straight to the right page.
Does anyone know what my possibilities are to get some of this magic in my product search? Are there some API's i can use? Some super free text option that i don't know of? Or ...
We solved a similar problem with quite some success: Searching for people (german names) by name given over phone.
E.g.: The very common german last names "Schmidt", "Schmitt", "Schmied", "Schmid", "Schmit" and "Schmiedt" will be all but impossible to hold apart when given by a voice. Combine this with a first name of "Sylvia" or "Silvia" or "Sylvya" and a caller saying "Hi, I'm Sylvia Schmidt, I have forgotten my customer number" has no chance of being quickly found.
Our solution was to put up a list of synophones, e.g. (in pseudo code, for german):
{consonant}+ := {consonant}
ie := i
ii := i
dt* := t
y|j := i
{vocal}v := {vocal}f
etc., you get the drift. Now we stored the synophone-translated strings with the original strings to make search possible. This works really well.
I understand that MySQL has the Soundex() function for English strings. I would expect MSSQL to have something similar.
