I found that if I search an IUIAutomationElement whose name contains whitespace, the FindFirst method returns nullptr, instead of the correct answer.
uiaPtr->CreatePropertyCondition(UIA_NamePropertyId, _variant_t(L"Alisha Chinai"), &search_condition);
//
auto ret = parent_uia->FindFirst(TreeScope_Subtree, search_condition, &target_uia);
I checked that the target_uia element I expect returned in the tree.
How can I fix this?
If my understanding is correct, you are looking for an object property of name that contains white space.
In that case, you can search with \n. For example, "sports\ncar".

I'm trying to change the value of nulls to something else that can be used to filter. This data comes from a QVD file. The field that contains nulls, contains nulls due to no action taken on those items ( they will eventually change to something else once an action has been taken). I found this link which was very informative but i tried multiple solutions from the document to no avail.
What i don't quite understand is that whenever i make a new field (in the script or as an expression) the formula does not propagate in the records that are null, it shows " - ". For instance, the expression isNull(ActionTaken) will return false in a field that that not null, but only " - " in fields that are null. If i export the table to Excel, the " - " is exported, i copy this cell to a text analyzer i the UTF-8 encoded is \x2D\x0A\x0A, i'm not sure if that's an artifact of the export process.
I also tried using the NullAsValue statement but no luck. Using a combination of Len & Trim = 0 will return the same result as above. This is only one table, no other tables are involved.
Thanks in advance.
I had a similar case few years ago where the field looked empty but actually it was filled with a character which just looked empty. Trimming the field also didnt worked as expected in this case, because the character code was different
What I can suggest you is to check if the character number, returned for the empty value, is actually an empty string. You can use the ord to check the character number for the empty values. Once you have the number then you can use this number to replace it with whatever you want (for example empty string)
We use Apache UIMA Ruta for processing our documents. The input documents contains all kind of patterns that we try to recognize and translate to a hierarchy of annotations.
One of the things we will do with the result is to decorate the input text with links. For that it's import that we know the original position information of the found annotations.
Some of the annotations are based on value lists. We use MarkTable to resolve them.
The problem we have is that input document can contain different kind of special entities. For example, the document can contain also words that contain entities like & 𝌆. These can also exist in words / sentences that will be looked up into valuelists.
We are searching for an option to generalize (convert) all that kind of options to a normal "plain text" format, so that we don't have to add all kind of options, with special entities to the valuelists.
Doing a pre-processing of the document and replace them all (for example with the HTMLConverter engine) is AFAIK not a good option, because that will also change the position info. & should match on &, but still seen as size 5.
I tried to use the replace action, that will add an extra "replacement" attribute to the annotation. When I add an interceptor (aspect) to the getCoveredText of the annotation class, and return replacement instead of real text if available, the matching will succeed. But this give problems if the replacement text contains spacers (the end position is still equal with the original text / first RutBasic).
Any suggestions how we can solve this?
I solved this issue by building a pre- and post processor for the content.
In the pre-processor I replace text fragments with other text. For example the & and & will be replaced by a normal &. While preprocessing I store each replacement details in an replacement object, that will be added to an ordered list. A replacement object contains the original text and the difference in length (& is 4 characters longer than a single &).
After annotating with RUTA(and other annotators) I correct all the found annotation values (text) to the original value and I fix the position information (begin and end) of the annotations, so that they match with the original content. I use the list with replacement details for this process.
In word, I'm using docvariables to manage pluralization.
A VBA macro is changing the value of several docvariables to pluralize / singularize them.
But sometimes I want to use a Docvariable only for enable/disable a 's' suffix.
Problem: I cannot set it to empty string, because it deletes the docvariable.
The field displays an error in word.
So I'm searching a way to achieve this, it could be :
A way to keep a Docvariable existing, with empty string or equivalent value
A field formula which make this job if the variable doesn't exist
Any other workaround would be appreciated.
Thank you
A Document Variable (used in DocVariable field codes) cannot exist if it has no content.
A possibility would be to also store the space in this DocVariable so that it display s[space] or just [space].
Otherwise you may need to write this information to a Bookmark (possibly using a Set field) and display the content using a Ref field.
I call my statement with CONTAINS function, but sometimes it does not return correct records, e.g. I want to return row which contain in one field word 'Your':
SELECT [Email]
,[Comment]
FROM [USERS]
WHERE CONTAINS(Comment, 'Your')
It gives mi 0 result despite that this field contains this word (the same with 'as', 'to', 'was', 'me'). When I use 'given' instead of 'Your' then I receive a result. Is there maybe a list of words which cannot be used with CONTAINS? Or maybe this words are to short (when i use 'name' then i receive the results)? The work 'Your' is at the beginning in field Comment.
The field is of type 'text' and has enabled full-text index.
Words such as those you mention are "stop words"; they are expressly excluded from being indexed and searched in Full Text Search due to how common (and thereby meaningless for searches) they are. You'll notice the same thing when searching Google, for instance.
It is possible to edit the list, but I would avoid doing so except perhaps to add words to it; the words in the list are chosen very well, IMHO, for their lack of utility in searches.
For a specialized calculator I would like to allow copy / paste for a textfield which is meant for numerical values only. So, only numerical characters should be actually pasted or the pasted string should be rejected if it contains non-numerical characters.
I was thinking about using UITextFieldDelegates textField:shouldChangeCharactersInRange:replacementString: method to check the pasted string for non-numerical characters. But NSString offers no method for checking whether it does NOT contain characters specified in a single set. So this way I would need to check occurances of characters from several sets, which is clumsy and these checks would run for every single number that would be typed in, which appears like quite some overhead to me.
Another way would be to iterate and check for every character in the replacement string whether there's a match in a numerical set.
Either way would propably work, but I feel like I'm missing something.
Do you have any advice? Is there a convenience method to achieve this?
But NSString offers no method for checking whether it does NOT contain characters specified in a single set
sure it does.
if([myString rangeOfCharacterFromSet:myCharacterSet].location ==NSNotFound)
{
//means there is no character from specified set in specified string
}
