When fields are nested, there is a problem.
foreach (Word.Field field in this.Application.ActiveDocument.Fields)
{
field.Update();
text = field.Result.Text;
}
The above code does not work.
The process starts, but winds up in an endless loop or some other process that hangs the system.
Thinking about it, I can surmise that when you update a field, it might have an effect on the fields collection - thus, the loop fails.
Does anyone have any ideas on implementing this?
P.S. I know there is a Document.UpdateFields() method to update ALL fields. However, there are reasons why I cannot use this and need to only update specific field types.
My apologies! I was going to give an example of a nested field but was trying to test some more before sending anyone (Jack) on a goose-chase.
I waited and waited and waited, and after a good 2 or 3 minutes, it finished. After the last field, it crashed with this message:
Object has been deleted.
The error was generated from the following line inside the loop:
string text = field.Code.Text;
The template is being tested on mergefields that are not being found because I am testing without database connectivity. It would be odd, but explainable, that it goes through all the fields and then, at the end of the day, the very OUTER IF field's result is "Error! Reference source not found." But I still don't get why this could happen.
Nor do I understand why looping takes 3 minutes while a call to document.Fields.Update() will do the same thing in about 1 second and NOT result in the error described above.
Again, my apologies. I never considered updating inside a loop would be vastly slower that a call to doc.fields.update().

I have a Protractor test that pulls various values from the UI and stores them as variables for comparison with values from a different database.
Now this test needs to run against multiple sites BUT of the 25 maximum data points recorded, some sites only have 22.
Clearly the test fails on those "22" sites since the elements are not present.
What I want to achieve is where there's a "22" site, the tests against the not present elements are ignored and the test proceeds to the end. Conveniently, the "missing" elements are the last ones in the spec.
Crudely speaking...
if element-y is not present end test or if element-y is present continue
Grateful if anyone could advise.
Thanks #sergey. I've modified your example as below....
if (!(await element(by.xpath('//*[#id="root"]/div/div[2]/main/div/div/section[5]/div/div/div[1]/section/div/span')).isPresent())) {
console.warn ('Functions are not present, closing the session')
await browser.close()
I get this error:
if (!(await element(by.xpath('//*[#id="root"]/div/div[2]/main/div/div/section[5]/div/div/div[1]/section/div/span')).isPresent())) {
^^^^^^^
SyntaxError: Unexpected identifier
I've tried using a 'var' instead of the actual element, but get the same result.
Thanks
well the best option that I recall is still pretty dirty... you can do something like this
if (!(await element.isPresent())) {
console.warn('Element not present, closing the session')
await browser.close()
}
And then the rest of test cases will fail as session not found or similar error
The reason you can't do anything better because in protractor you can't do conditional test cases based on a Promise-like condition, if that makes sense...
i´ve a quick question regarding a zabbix trigger expression. Our script finds out the certification lifetime while returning a number into a file. I already created some triggers for specific time spans (like 10 days or 44 days).
For example:
{Certificate Lifetime:vfs.file.contents[C:\Zabbix_scripts\cert.txt].prev()}<=30 and {Certificate Lifetime:vfs.file.contents[C:\Zabbix_scripts\cert.txt].prev()}>10
I now want to have a trigger which will cause an "Disaster" when the value in the .txt file is unavailable, like the txt file is empty.
I´ve tried
{Certificate Lifetime:vfs.file.contents[C:\Zabbix_scripts\cert.txt].prev()}=0
But this was not the right sulution. Any ideas?
Moreover we have some machines which are equal to others but doesn´t show any value. Any ideas at this point?

You should be able to detect empty item value with something like this:
strlen()=0
I have a form that loads a single record. The user does what they need to do on the form...in this case, they enter a date, and a button becomes available to click to advance the record to the next step in the process.
I have a public function that is logging the activity to tblActivity, and sets the record's new Status and Location. This Function takes 3 variables, and was working fine until today.
'I'm calling the function with this line from the button's Click event
LogActivity 15, Screen.ActiveForm, Me.Recordset
Public Function LogActivity(ByVal lSID As Long, Optional fForm As Form, Optional ByRef fRS As Recordset)
With fRS
Do Until .EOF
Debug.Print .Fields(5)
.MoveNext
Loop
End With
...
End Function
This should be printing the form's Status value, but fRS is passed in with no values. The form's recordset has values prior to being passed as the form has data. Some how it is getting lost in the pass. This was working fine, I have multiple buttons across 5 different forms that all call this same Function. Suddenly today, none of them can pass the recordset. I can think of nothing that was changed that would effect this. Most of the changes recently involved locking down fields and the appearance of buttons at the right time...nothing related to the recordset.
Naturally, this DB is supposed to go live on Monday.
Found the problem.
I had a backup from yesterday that was working fine.
One by one, I went through the changes I logged from yesterday and found that by changing some fields to .enabled = False and .locked = True is what was doing it. Apparently that was enough to clear all the values when passing.
Left the fields enabled, just locked them and it passes all values correctly.
Even though this was a failure on my part, I'll leave this up in case some one else makes the same mistake I made.
**** Update ****
I also found out that if I did a
fRS.movelast
fRS.movefirst
before anything else, it found the data. Not sure why it started happening, but these two things seem to have fixed it completely.
I'm writing a pretty big migration and had this code (coffeescript):
db.users.find().forEach (user)->
try
#some code changing the user depending on the old state
db.users.save(user)
print "user_ok: #{user._id}"
catch error
print "user_error: #{user._id}, error was: #{error}"
Some errors occured. But they occured on already processed users:
user_ok: user_1234
#many logs
user_error: user_1234 ...
How come the loop takes already processed objects?
I ended up doing:
backup = { users: [] }
db.users.find().forEach (user)->
try
#some code changing the user depending on the old state
backup.users.push user
print "user_ok: #{user._id}"
catch error
print "user_error: #{user._id}, error was #{error}"
#loop backup and save
And it works nice now, but it seems really weird. What's the point behind all that please?
When you modify an object, it might be moved by the database. The database needs to take additional care to remember which objects have been visited already. This feature is called snapshotting, you can ask for a snapshotted query using
db.collection.find().snapshot()
However, even this doesn't make guarantees about objects that were inserted or deleted during the cursor iteration. A few more caveats are explained in the link to the documentation.
Another option is to perform an $orderby on an invariable unique index. Ideally, that index is also monotonic, so if you are using ObjectIds as primary keys then the _id field comes in pretty handy, like
db.collection.find().sort({"_id" :1});
I'm building a form with Yii that updates two models at once.
The form takes the inputs for each model as $modelA and $modelB and then handles them separately as described here http://www.yiiframework.com/wiki/19/how-to-use-a-single-form-to-collect-data-for-two-or-more-models/
This is all good. The difference I have to the example is that $modelA (documents) has to be saved and its ID retrieved and then $modelB has to be saved including the ID from $model A as they are related.
There's an additional twist that $modelB has a file which needs to be saved.
My action code is as follows:
if(isset($_POST['Documents'], $_POST['DocumentVersions']))
{
$modelA->attributes=$_POST['Documents'];
$modelB->attributes=$_POST['DocumentVersions'];
$valid=$modelA->validate();
$valid=$modelB->validate() && $valid;
if($valid)
{
$modelA->save(false); // don't validate as we validated above.
$newdoc = $modelA->primaryKey; // get the ID of the document just created
$modelB->document_id = $newdoc; // set the Document_id of the DocumentVersions to be $newdoc
// todo: set the filename to some long hash
$modelB->file=CUploadedFile::getInstance($modelB,'file');
// finish set filename
$modelB->save(false);
if($modelB->save()) {
$modelB->file->saveAs(Yii::getPathOfAlias('webroot').'/uploads/'.$modelB->file);
}
$this->redirect(array('projects/myprojects','id'=>$_POST['project_id']));
}
}
ELSE {
$this->render('create',array(
'modelA'=>$modelA,
'modelB'=>$modelB,
'parent'=>$id,
'userid'=>$userid,
'categories'=>$categoriesList
));
}
You can see that I push the new values for 'file' and 'document_id' into $modelB. What this all works no problem, but... each time I push one of these values into $modelB I seem to get an new instance of $modelA. So the net result, I get 3 new documents, and 1 new version. The new version is all linked up correctly, but the other two documents are just straight duplicates.
I've tested removing the $modelB update steps, and sure enough, for each one removed a copy of $modelA is removed (or at least the resulting database entry).
I've no idea how to prevent this.
UPDATE....
As I put in a comment below, further testing shows the number of instances of $modelA depends on how many times the form has been submitted. Even if other pages/views are accessed in the meantime, if the form is resubmitted within a short period of time, each time I get an extra entry in the database. If this was due to some form of persistence, then I'd expect to get an extra copy of the PREVIOUS model, not multiples of the current one. So I suspect something in the way its saving, like there is some counter that's incrementing, but I've no idea where to look for this, or how to zero it each time.
Some help would be much appreciated.
thanks

OK, I had Ajax validation set to true. This was calling the create action and inserting entries. I don't fully get this, or how I could use ajax validation if I really wanted to without this effect, but... at least the two model insert with relationship works.
Thanks for the comments.
cheers
