Along a similiar vein to this question, I'd like to store only white space in an Ax2009 table field.
...We want to be able to store " " (string containing one space or more) in a field (the field content is exported to a plain text file later on).
After an insert, the value remains " ", but if we do a Select on the table the value is replaced by "".
Any suggestions? Thanks.
You can check the workaround used in standard AX for field AddressFormatLines.Separator
An additional field NumOfSpaces is used to overcome this AX limitation, methods insert, update, and postLoad are overridden accordingly, and as a result you can store a white space and also see it in forms (although you won't see it in SQL Server).
Sorry, but trailing spaces are removed.
Live with it.
there is actually a way of storing a white space at the end of a string field. Instead of using the normal space bar enter Alt+255. That will create a space which is not removed.

This is on Numbers on Mac: I generate a paragraph of text from a row where columns hold parts of text. However, as some cells are empty, I had to use conditional ISEMPTY for the formula to work:
""&B9&" "&IF(ISBLANK(C9);"";C9)&" "&IF(ISBLANK(D9);"";D9)&" "&IF(ISBLANK(E9);"";E9)&" "&IF(ISBLANK(F9);"";F9)&" "&G9&" "&H9&""
This does function, but I end up with double spaces in areas where I have one or more columns empty (so the spaces double).
Is there a way I could use an another conditional like ISEMPTY(ISEMPTY...) to get rid of those?
This is not a huge problem, but is annoying and time consuming, because I have to fix these texts afterwards (there is a lot of them). :-(
Change the parts with &" "& from IF(ISBLANK(C9);"";C9)&" "&into IF(ISBLANK(C9);"";C9&" ")&
In your formula you check if C9 is blank. Whether blank or not it's followed by a " " space. So if blank you get a space added, but no data prior to it. If the next is empty too, you get another space without data etc..
By including the &" " inside the if statement it will only add a space if C9 is not blank. Blank cell adds no data and no space.
=TRIM(CONCATENATE(B9;" ";C9;" ";D9;" ";E9;" ";F9;" ";G9;" ";H9))
Maybe you should learn about TEXTJOIN..
I got a CSV file from my front-end as a XString and after I convert it into String it looks as follows:
In the next step I'm trying to perform SPLIT lv_string AT '##' INTO TABLE itab so I can get my data but it doesn't split anything, itab contains one line equal to lv_string.
If I try REPLACE '#' IN lv_string WITH space, lv_string doesn't change and sy-subrc is 4.
From my point of view I have this problem because the symbol # is used by SAP in this context as a symbol for non-printable symbols (that result from the conversion byte->string).
My question is: how may I use SPLIT/REPLACE with # in this case?
I also thought that I can change the SAP code page when converting XString to String but I already use the SAP code page 4110 (utf-8) and don't know a better alternative...
When you display a variable with the debugger, it displays the generic character # (U+0023) for all control characters which are not assigned a glyph ("non-printable symbols" as you say).
If the variable corresponds to the contents of a text file, and ## frequently occurs, there is a big chance that it's the combination of the control characters U+000D and U+000A which correspond to "newline" in Windows files.
In the backend debugger, you can check the hexadecimal values of those characters by clicking the button "Hexadezimal" (shown in your screenshot).
You may use the variable CL_ABAP_CHAR_UTILITIES=>CR_LF which contains those two control characters.
I need to remove an invalid word from the vocab of a "gensim.models.keyedvectors.Word2VecKeyedVectors".
I tried to remove it using del model.vocab[word], if I print the model.vocab the word disappeared, but when I run model.most_similar using other words the word that I deleted is still appearing as similar.
So how can I delete a word from model.vocab in a way that affect the model.most_similar to not bring it?
There's no existing method supporting the removal of individual words.
A quick-and-dirty workaround might be to, at the same time as removing the vocab entry, noting the index of the existing vector (in the underlying large vector array), and also changing the string in the kv_model.index2entity list at that index to some plug value (like say, '***DELETED***').
Then, after performing any most_similar(), discard any entries matching '***DELETED***'.
Refer to:
How to remove a word completely from a Word2Vec model in gensim?
Possible method 1: I solve it by editing the text model file itself.
Possible method 2: Refer to #zsozso's answer. (Though I didn't get
it to
work).
I am creating a Joomla component and one of the pages contains a form with a text input for an email address.
When a < character is typed in the input field, that character and everything after is not showing up in the input.
I tried $_POST['field'] and JFactory::getApplication()->input->getCmd('field')
I also tried alternatives for getCmd like getVar, getString, etc. but no success.
E.g. John Doe <j.doe#mail.com> returns only John Doe.
When the < is left out, like John Doe j.doe#mail.com> the value is coming in correctly.
What can I do to also have the < character in the posted variable?
BTW. I had to use & lt; in this question to display it as I want it. This form suffers from the same problem!!
You actually need to set the filtering that you want when you grab the input. Otherwise, you will get some heavy filtering. (Typically, I will also lose # symbols.)
Replace this line:
JFactory::getApplication()->input->getCmd('field');
with this line:
JFactory::getApplication()->input->getRaw('field');
The name after the get part of the function is the filtering that you will use. Cmd strips everything but alphanumeric characters and ., -, and _. String will run through the html clean tags feature of joomla and depending on your settings will clean out <>. (That usually doesn't happen for me, but my settings are generally pretty open to the point of no filtering on super admins and such.
getRaw should definitely work, but note that there is no filtering at all, which can open security holes in your application.
The default text filter trims html from the input for your field. You should set the property
filter="raw"
in your form's manifest (xml) file, and then use getRaw() to retrieve the value. getCmd removes the non-alphanumeric characters.
I'm using VB6 and ADO together with the Microsoft Text Driver to import data from an ASCII file. The file is comma delimited but it also contains double quotation marks around text data fields. The fields are also fixed width.
I'm having a problem that the driver reads the columns incorrectly any time one of the rows contains a quotation mark double quotation inside the content. This happens inside the "part description" column which is the second column from the left. When this occurs, columns to the right are all Null value, which is not the case in the text file.
I think it would be better to use only the commas as delimiters. However, I believe that commas also occur in the "part description" column so this means I should really load the file as fixed width. I'm not aware that there is any way of doing this unless I can specify this in the schema.ini file.
Any ideas on how to resolve this?
Edit:
You are allowed to specify fixed width in your Schema.ini file. However, it appears to me that the commas and quotation marks that also exist as delimiters/qualifiers will prevent this from working properly. It looks like I may have to "manually" read the file in and write it back out in my own format before I load it using the MS Text driver. Still looking for other opinions.
I would try changing the Format value in the registry for the Jet text engine (if that's what you're using) at the key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Jet\4.0\Engines\Text. I think the default is CSVDelimited but you would change this to FixedLength. See http://msdn.microsoft.com/en-us/library/ms974559.aspx
It's probably worth adding that although you have a Schema.ini file for settings, on some options the registry overrules them anyway
Actually, looking at the link I supplied, it seems you have to use a schema.ini file for fixed-length files. Have you tried something like the following, which specifies the width?
[Test.txt]
Format=FixedLength
Col1=FirstName Text Width 7
Col2=LastName Text Width 10
Col3=ID Text Integer 3
I'm extra precautious with regional settings -- some users change default list separator. Usualy fix this with schema.ini like this:
[MyFile.csv]
Format=Delimited(,)
