I'm working with a ASP.Net MVC4 application using C3 and the Razor engine!
I have a database called builds which contains various columns, like version, creation date.
The database has doubles of Versions, i.e 4.0.230, 4.0.230, 4.0.229, 4.0.229. This is because to tell which version correspond to which environment. like if the Version isX64 etc.
So there is a Version for each environment.
I have a Entity Framework line asking to retrieve the last 10 builds:
var lastVersions = db.Builds.OrderByDescending(b => b.CreationDate).Take(10).Select(b=>b.Version);
so im ordering them by creation date and taking the last 10
it looks like this
4.0.240
4.0.240
4.0.239
4.0.239
4.0.238
etc
then with this line of code:
ViewBag.Versions = lastVersions.Distinct().ToArray();
I would like: [4.0.240, 4.0.239, 4.0.238, 4.0.237, 4.0.236]
but i get: [4.0.236, 4.0.237, 4.0.238, 4.0.239, 4.0.240]
Basically the OrderbyDescending is not working.
Please Help
All help is much appreciated!
thanks!
Without seeing your database, it looks like your OrderByDescending is indeed working, but you actually need to order twice. Your first time, you order by creation date to get the most recent 10 builds, but then after the select, the order is not guaranteed anymore when stuffed into a var. You must sort again by version number. Assuming ViewBag.Versions is a string[], you could do:
Array.Sort(ViewBag.Versions);
or
Array.Reverse(ViewBag.Versions);
if they are in ascending order initially.

I need to create simple query which will show all contracts which will expire in next 3 months. I know how to do that with SQL, but how to do that in Visual Studio when I create query. I added data source Contract table. Added range. Column where is date about expiring is VALIDTO.
So, something to write up in value, or how to do that ?
Solved with two ranges on VALIDTO column. Used (MonthRange(0,3)) with (Day(0)) formulas.
I want to synchronize data for actual work from a web-based application of my company with MS Project. I am currently developing an Add-In with JavaScript in order to achieve this:
The red circle in my screenshot shows the data that I want to set programmatically. However, I have no idea how to achieve this.
I understand that I can get Task GUIDs and then set task fields using the task GUID and the field ID. This way I can save the cumulative actual work, but not per day like in my screenshot.
The API Docs on the MS Office Website are rather hard to read and navigate. Any help would be apprechiated!
Let's first separate the language from the operation.
Operationally, based on your circle, you want to set work for a task to happen on individual days? This is done using timeScaleData, see https://learn.microsoft.com/en-us/previous-versions/office/developer/office-2003/aa206255(v=office.11) . When I did something similar (in VBA), I had to (1) get an array of time scale values, then (2) walk/iterate through that array and set work to those days:
set timeScaleValsArry = myTask.Assignments(1).TimeScaleData(startDay, endDay, pjAssignmentTimeScaledWork, daily)
for a = 1 to timeScaleValsArry.Count
timeScaleValsArry[a].value = hoursToWorkThatDay
next
Breaking down the elements above:
myTask is the task (of type task) I want to manipulate.
Assignments is an array representing each resource assigned to the task; for my purposes, I only ever had 1 resource assigned, hence the index of (1).
TimeScaleData is the function that returns the the array starting on the day startDay (whatever you want that to be), endDay, pjAssignmentTimeScaledWork which tells this function what data we want to work with (being work, but there are alternates ), and daily which is the frequency you want to work with (for instance you can go down to minutes, or up to years).
Then the returned array timeScaleValsArry is walked, and inside the loop the daily assignment for each value is manipulated. You'd need to customize this part to meet your needs; alternatively, you don't even need to loop if you always had three days: just hard code the array indices.
As far as language, clearly this is do-able in VBA. Doing this in C# as a VSTO addin has very similar syntax. I'd presume for JavaScript (what are you using, ScriptLab?) would also have similar syntax.
I am trying to build a PowerApp to log setup times of our machines by our fitters.
This is what my app looks like:
There are buttons named "Uhrzeit". Pressing these will write the current date and time into the Date/Time fields. I am using the following code:
UpdateContext({Total8:(Text( Now(); "[$-de-DE]dd/mm/yyyy hh:mm:ss" ))})
The Date/Time field is named Total8.
The code is working well but after saving the form and opening a new record the old data is still available in the fields. By clicking on the button "Zeiten zurücksetzen" I can "delete" the old data.
UpdateContext({Total8:""})
Problem: When I open one of the older records the old data is not available in the form. There is only the value of the last record. In the Common Data Service where my records are saved the values are correct.
As an example, I am saving this record:
When I open a new record, the values of the record 1 are still available. This should not be the case if my app worked properly.
For your Information:
If I enter the date/time without tapping the button, saving the record and opening a new record I don't have the problem. I think the "UpdateContext" code is not the code I should use here.
Can anyone help me solve the problem?
I don't think there's a problem with using the contexts in this way -- but remember that a context is just a variable. It isn't automatically linked to a datasource in any special way - so if you set it equal to Now(), it's going to keep that value until you do something different.
When you view an old record, you need to get the data from CDS and update your contexts to match the CDS data. Does this make sense?
Yeah thats my problem.
I want the variable to be linked to a datasource. Or is it possible to write the date/time into the fields without using a context variable?
For my pourpose I need to sort Employee app list items by last modified date.
I see that in the object there is a Modified that is a date field (I assume it is a 2sxc internal field).
Using the Value sort datasource setting Modified as attribute I get an empty object.
It does work using my custom fields as sorting attribute.
What I'm missing please?
I believe the value-filter didn't include modified till very, very recently, like v08.05.04 or similar. Since then I believe it was added - see https://github.com/2sic/eav-server/blob/master/ToSic.Eav.DataSources/ValueFilter.cs#L146-L167
So I believe if you upgrade it should work.
I have a problem that I've been going round and round with in Access 2010. Imagine a table with these columns:
Name Date Time
Now, I have a query that asks the user to input a begin date and an end date and returns all records that are between those two dates. This works fine. However, as soon as I add a sort to the Date column things go awry. Once you put a sort on a column with a parameter the user gets asked to enter the parameter twice. From what I've been able to find out this is normal (although annoying) behavior in Access.
If I add the Date column in a second time and show the column with the sort and don't show the column with the parameter it works fine. The query would look something like:
Name Date (shown & sorted) Date (not shown & parameters) Time
Now when I run the query it all works well and comes out the way I want it to. This would obviously be a great solution then. However, there's another problem. When I save the query, leave, and reopen the query the two columns are merged back into each other. Thus, the change is lost and the user again sees two inputs.
My question is this: what can I do differently to achieve the desired results?
Some possible things I've thought about but don't know the answer to are:
Is there a way to make it so the columns don't merge? Do I have to use a form with the input boxes and take the data from that (I'd prefer not to do that as it will require a lot of additional work to handle the various things I am doing in the database). Is there some obvious thing I'm missing?
Thanks for any suggestions.
FYI: Here is the SQL from the query
SELECT Intentions.Intention, Intentions.MassDate, Intentions.[Time Requested], Intentions.[Place Requested], Intentions.[Offered By], Intentions.Completed
FROM Intentions
WHERE (((Intentions.MassDate) Between [Enter start date] And [Enter end date]))
ORDER BY Intentions.MassDate, Intentions.[Time Requested];
It is true that sometimes the Query Designer in Access will "reorganize" a query when you save it. However, I don't recall an instance where such a reorganization actually broke anything.
For what it's worth, the following query seems to do what you desire. After saving and re-opening it looks and behaves just the same:
For reference, the SQL behind it is
PARAMETERS startDate DateTime, endDate DateTime;
SELECT NameDateTime.Name, NameDateTime.Date, NameDateTime.Time
FROM NameDateTime
WHERE (((NameDateTime.Date) Between [startDate] And [endDate]))
ORDER BY NameDateTime.Date DESC , NameDateTime.Time DESC;
I have had the same problem and I have discovered the reason:
If, after you have run your query, sort a collumn in the result grid and the say yes to save changes to the query the sort action will be stored with the query. This will actually cause the query to run twice. First to create the result and then one more time to sort. You'll therefore be asked twice for the parameters.
SOLUTION: Run the query (entering your parameters twice ;-) ). Then remove the Sorting by clicking on the AZ-eraser symbol in the task bar above (in the sorting compartment).
Then open your query in design-mode and add the sorting order to the appropriate collumn.
Your are then good to go.
