• ssrs: one static row matrix, multiple columns will not filter out nulls

  - by pbarton99

  Using a ssrs 2005 matrix client side. I want to list the multiple addresses of one person, hence one row, multiple columns. The Column field is =Fields!StreetName.Value. The data details field is =First(Fields!StreetPrefix.Value) & " " & First(Fields!StreetName.Value). The datasource has a row for each address; however, some rows will have nulls since the datasource is composed of outer joins. The column grouping works, but the first column is always empty, (first 2 rows of datasource are null) addresses appear only after the empty column. I want to filter out nulls on the matrix, but its like the filter is ignored. I have also tried having the dataset return an empty string for a null streetname and setting the filter to =Fields!StreetName.Value != ="" but no difference. What am I missing?

• How to programatically create a xaml panel with controls

  - by randy

  Hello, Is it possible to programatically create a new panel within a current document that contains duplicate elements? For example when the window loads I have a grid (one row) with three text fields, Fname01, Lname01, and DOB01, I would like to have a button that when clicked would append a new row to the grid with three new fields (Fname02, Lname02, and DOB02). Each time the button is clicked (addrow) a new row would be created. I am also interested to learn how these fields are identified within the xaml that would allow me to databind or programatically reference the created fields for insertion of the values into a database etc. Thank you in advance,

• SSRS Dynamic Returning Dataset Collection Field in Expression

  - by Ray Clark

  I wrote a custom assembly to take a parameter value from the report and return a field from the dataset collection. My assembly returns the correct fields!name.value, but it shows me the string representation of it. How can I get it to resolve as the actual fields!name.value to display the actual data in the dataset? If I enter fields!name.value in manually it works fine showing me the value. If I resolve it with my custom code it display "fields!name.value" to me in the cell.

• Merge two lists of objects which hold different data

  - by C.McAtackney

  I have an object "Project" which has a number of fields, one of which is "Name". I have one spreadsheet of projects which contains some of these fields, and another which contains the rest. However, Both spreadsheets have the "Name" field. I've read them in and populated two List, only populating the available fields from that particular source. E.g. a Project from List 1 looks like; {Name="MyProj", Type="Form", Priority=NULL}, whereas a Project from List 2 {Name="MyProj", Type=NULL, Priority="High"}. Now, I want to merge these two lists into one in which each Project object has all of its fields populated, with the Name field being used to match the elements. How can I achieve this? Are there any nice ways of doing this concisely? Thanks

• association of more than one model to a listview

  - by Veer

  I have 3 Tables in my database. Each table has 3 fields each, excluding the ID field. out of which 2 fields are of type nvarchar. None of the tables are related. My ListView in the application helps the user to search my database, the search being incremental. The search includes the nvarchar fields of the 3 tables ie, 6 fields in total. Eg: PhoneBook: Name, PhoneNo Notes: Title, Content Bookmarks: Name, url I've the models generated for the 3 tables. Now the ListBox should display the Ph.Name, Title and the Bo.Name fields. ie, It should be bound to them. But they are from different models. I also should be able to perform CRUD operation on the item searched. How would i do that? P.S: Separate ViewModels are created for each Model which are used for their respective views for handling those tables individually. But this is an integrated view where the user should be able to search everything. Also please somebody suggest me a better Title for this question:)

• Adding a Third Table to a Two-Table Join Query

  - by John

  Hello, The query below works just fine. It pulls fields from two MySQL tables, "comment" and "login". It does this for rows where "username" in the table "login" equals the variable "$profile." It also pulls fields for rows where "loginid" in the table "comment" equals the "loginid" that is also being pulled from "login." I would like to pull data from a third table called "submission," which has the following fields: submissionid loginid title url displayurl datesubmitted I would like to pull fields from rows in "submission" where "loginid" equals the "loginid" that is already being pulled from the other two tables, "login" and "comment." How can I do this? Thanks in advance, John Query: $sqlStrc = "SELECT l.username, l.loginid, c.loginid, c.commentid, c.submissionid, c.comment, c.datecommented FROM comment AS c INNER JOIN login AS l ON c.loginid = l.loginid WHERE l.username = '$profile' ORDER BY c.datecommented DESC LIMIT 10";

• Muliple Models in a single django ModelForm?

So I need to include some fields from the User model and the UserProfile model. Currently I am using 2 forms like this class UserEditForm(ModelForm): class Meta: model = User fields = ("first_name", "last_name") class UserProfileForm(ModelForm): class Meta: model = UserProfile fields = ("middle_name", "home_phone", "work_phone", "cell_phone") Is there a way to consolidate these into one form or do I just need to create a form and handle the db loading and saving myself?

• C# Design a class with interface?

  - by Haroon

  I am having a bit of trouble understanding how I will design a class. My class will have 3 methods ICollection<Field> GetFields(); //perform validation internally - return back the object T UpdateFields(ICollection<Field> fields); //pass in model object with values on it, set up fields, then pass back all fields ICollection<Field> GetFieldsWithValues(T object); What is the best way to construct/design such a class keeping in mind: 1. The model object I pass in will be one of 3 or 4 tables, however when I call GetFIelds - internally for each object I know what fields will be there i.e. list.add(new Field{name = "id", value = "5"}); list.add(new Field{name = "nameofcompany", value = "super guys"});

• How to subtract dates in YYYYMMDD format?

  - by NinjaBomb

  I have 2 integer fields that represent dates in the YYYYMMDD format. What is the best way to subtract 2 of these fields to get the correct # of days between them? For instance, if I take the difference between 20100511 and 20100428 I would like the result to be 13 and not 83. I know I need to convert the integer fields into date formats but everything I have tried either throws an exception or doesn't work correctly. What am I missing? Answers in vb.net please

• PHP: find 2 or more numbers from a list of N numbers that can add up towards a given ammount

  - by Splash

  Hi Guys, I am trying to create a little php script that can make my life a bit easier. Basically, I am going to have 21 text fields on a page where I am going to input 20 different numbers. In the last field I will enter a number let's call it the TOTAL AMMOUNT. All I want the script to do is to point out which numbers from the 20 fields added up will come up to TOTAL AMMOUNT. Example: field1= 25.23 field2= 34.45 field3= 56.67 field4= 63.54 field5= 87.54 .... field20= 4.2 Total Ammount= 81.90 Output: field1+fields3=81.90 Some of the fields might have 0 as value because sometimes I only need to enter 5-15 fields and the maximum will be 20. If someone can help me out with the php code for this, will be greatly appreciated.

• Django ORM dealing with MySQL BIT(1) field

  - by Carles Barrobés

  In a Django application, I'm trying to access an existing MySQL database created with Hibernate (a Java ORM). I reverse engineered the model using: $ manage.py inspectdb > models.py This created a nice models file from the Database and many things were quite fine. But I can't find how to properly access boolean fields, which were mapped by Hibernate as columns of type BIT(1). The inspectdb script by default creates these fields in the model as TextField and adds a comment saying that it couldn't reliably obtain the field type. I changed these to BooleanField but it doesn't work (the model objects always fetch a value of true for these fields). Using IntegerField won't work as well (e.g. in the admin these fields show strange non-ascii characters). Any hints of doing this without changing the database? (I need the existing Hibernate mappings and Java application to still work with the database).

• Best way to sign data in web form with user certificate

  - by salgiza

  We have a C# web app where users will connect using a digital certificate stored in their browsers. From the examples that we have seen, verifying their identity will be easy once we enable SSL, as we can access the fields in the certificate, using Request.ClientCertificate, to check the user's name. We have also been requested, however, to sign the data sent by the user (a few simple fields and a binary file) so that we can prove, without doubt, which user entered each record in our database. Our first thought was creating a small text signature including the fields (and, if possible, the md5 of the file) and encrypt it with the private key of the certificate, but... As far as I know we can't access the private key of the certificate to sign the data, and I don't know if there is any way to sign the fields in the browser, or we have no other option than using a Java applet. And if it's the latter, how we would do it (Is there any open source applet we can use? Would it be better if we create one ourselves?) Of course, it would be better if there was any way to "sign" the fields received in the server, using the data that we can access from the user's certificate. But if not, any info on the best way to solve the problem would be appreciated.

• How not to lose focus on a login page

  - by Misha Moroshko

  I have a simple login form with 2 input fields: "username" and "password". "username" field is focused by default. The problem is that when user clicks outside "username" or "password" fields, the focus is gone (it is neither on "username" nor on "password" fields"). How can I force the focus to be on these 2 fields only ? In my case, this is a really annoying behavior, so I really want to do this :) Can I do something like: $("*").focus(function() { if (!$(this).hasClass("my_inputs_class")) { // How to stop the focusing process here ? } }); ?

• How to enforce lazy loading of entities on certain conditions

  - by Samuel

  We have an JPA @Entity class (say User) which has a @ManyToOne reference (say Address) loaded using the EAGER option which in turn loads it's own @ManyToOne fields (say Country) in a EAGER fashion. We use the EntityQuery interface to count the list of User's based on a search criteria, during such a load all the @ManyToOne fields which have been marked as EAGER get loaded. But in order to perform a EntityQuery.resultCount(), I actually don't need to load the @ManyToOne fields. Is there a way to prevent loading of the EAGER fields in such cases so that we can avoid the unnecessary joins?

In one cae the toolbar was moving up with together with the table view, in the second case the table view overlaps the toolbar: All the ideas how to move the table view to make the cell being edited visible together with having the toolbar visible?

• Looking for MSSQL Table Design Sanity Check for Profile Tables with Dynamic Columns.

  - by Code Sherpa

  I just want a general sanity check regarding database design. We are building a web system that has both Teachers and Students. Both have accounts in the system. Both have profiles in the system. My question is about the table design of those Profile tables. The Teacher profile is pretty static regarding the metadata associated with it. Each teacher has a set number of fields that exposes information about that individual (schools, degrees, etc). The students, however, are a different case. We are using a windows service to pull varying data about the students from an endless stream of excel spreadsheets. The data gets moved into our database and then the fields appear in association with the student's profile. Accordingly, each and every student may have very different fields in their profile. I originally started with the concept of three tables: Accounts ---------- AccountID TeacherProfiles ---------- TeacherProfileID AccountID SecondarySchool University YearsTeaching Etc... StudentProfiles ---------- StudentProfileID AccountID Header Value The StudentProfiles table would hold the name of the column headers from the excel spreadsheets and the associated values. I have since evolved the design a little to treat Profiles more generically per the attached ERD image. The Teacher and Student "Headers" are stored in a table called "ProfileAttributeTypes" and responses (either from the excel document or via input fields on the web form) are put in a ProfileAttributes table. This way both Student and Teacher profiles can be associated with a dynamic flow of profile fields. The "Permissions" table tells us whether we are dealing with a Student or a Teacher. Since this system is likely to grow quickly, I want to make sure the foundation is solid. Can you please provide feedback about this design and let me know if it seems sound or if you could see problems it might create and, if so, what might be a better approach? Thanks in advance.
