In VB.NET (Not ASP.NET) what can I use for a daily calendar. I have done extensive DuckDuckGo and Google search and I have came up with no viable options.
The purpose of the calendar is to create a appointment system with multiple dentists therefore appointments also can run in parallel. However having it in parallel isn't required as I may have the end-use select what dentist the appointment is for (creating a appointment, therefore got to select a date/time).
The project is only a university/college project therefore having it perfect isnt a requirement (but I'd prefer it). I'd use anything, otherwise I'm going to have to use a ListView.

Thanks in advance.
Keep in mind people have already solved this problem... don't reinvent the wheel if possible. If you have some budget, try picking one from here. If not there are a couple of WinForms freeware/open source controls, such as this one.
Unless you shell out some money, you'll still have to write the actual scheduling part; these are just display controls.

I am somewhat struggling with a project that I have set myself to do:
I am attempting to create a Web application for ServiceDesk work schedule. The app would show a schedule on a principle of week/month/year with the option to change view and enable users to see a spreadsheet like schedule for their daily assignments. A similar view as such, just maybe less detailed.
I am trying to build it in Oracle Apex. Now I have narrowed it down to 2 possibilities in terms of layout: either I use calendar, in which the layout would be slightly different and would basically have to show each task with details of who and what, or I go for Gantt chart and make it so that the left side shows names of the employees and the upper side shows time in days/months/years.
What I am struggling with is whether one or the other is the right way to go. I am trying not to make it too complicated for the administrator to make changes (at the moment, the work schedule is in excel spreadsheet, updated every month) as that would be counterproductive and could make it worse to use than excel. Also, the reason why I chose Apex is the fast that the company I work for actually uses apex in a lot of the projects and would be a bit easier to integrate with the rest of the systems already in play.
Any tips or guidelines to follow would be greatly appreciated!
Jervis,
Based on your comment:
Apex Calendar region is not appropriate here, as the ability to customize it is very limited. You couldn't even get it to show the 30 days shown in your mock-up.
I don't think Apex Charts would allow the formatting you're looking for either.
You need a grid region of some sort where you can arrange and style it. You can try an Apex Interactive Grid region. That doesn't include drag-n-drop functionality out of the box and I don't know of a free plug-in adds that functionality. That will probably do the basics of what you want
If you can pay for a commercial Apex framework, I'd recommend the FOEX Enterprise framework, which adds a ton of functionality and interactivity, including editable grids that you can drag-n-drop. It's not cheap (per-developer licensing) and there's a learning curve because it's a different way of doing Apex, but it's a very solid product and you can buy consulting time from them.
(I'm a FOEX customer, not an employee or a shill)
I'm building a student schedule generator and I need a way of producing more than one solution. Is there some way to save off feasible scores or scores of Xhard/Ysoft?
I need to be able to output more than one potential schedule, that way the student will have a choice for one schedule over the other if for whatever reason they don't want the "best" schedule (maybe they don't like one of the professors, maybe they don't want an 8am class, whatever)
My original idea was to save off all feasible solutions using the bestSolutionChanged event listener. The problem with this, is that once it finds a 0hard/0soft score, it ignores all scores after that, including scores that are equal.
Ideally I'd like to save off all scores of 0hard/-3soft or better, but just being able to save any feasible scores or force optaplanner to look for a new best score would be useful as well.
This is not a solution, but an analysis of the problem:
Hacking the BestSolutionRecaller is obviously not just a big pain, it's also behaviour we don't want to encourage as it makes upgrading to newer version an even bigger pain. So don't expect us to solve this by adding an easy way to configure that in the solver config any time soon. That being said, a solution for this common problem is clearly needed.
When a new best solution is found, it is planning cloned (see docs for definition) from the working solution (the internal solution in OptaPlanner). This allow us to remember that new best solution as the working solution solution changes. That also means the BestSolutionChangedEvents gets a plannng clone and can safely ship it to another thread, for example to marshal it to a client (presuming any ProblemFactChanges you create do copies instead of alterations), without being corrupted by the solver thread that modifies the working solution.
New best solution imply that workingScore > bestScore. The moment it instead does workingScore >= bestScore, we need far more planning clones (which are a bit CPU expensive), but we could then just send out BestSolutionChangedEvents for that too, if and only if a flag is enabled of course, because most users (unlike yourself) don't want this behaviour.
One proposal is to create a separate BestSolutionChangedOrSameEvent, next to the BestSolutionChangedEvent. This might not be ideal, because we need to be able to detect whether or not someone needs those extra planning clones.
Another proposal is to just have a flag in the <solver> config that switches from > to >= behavior for BestSolutionChangedEvent.

As a way to score points for the study I’m doing, as well as out of interest into databases and wanting to help my team I’m trying to build a capacity planning tool in MS Access 2007. I work in a department that handles registering and supporting tenders. I have attached two pictures of what I’m trying to do here.
I’ve already spent some weeks making multiple iterations with colleagues who are involved and help write VBA and SQL (out of interest, wanting to learn something or otherwise. Our core business, however, isn’t developing). The primary goal of the database is as follows:
A user can access, create and modify “cases” that correlates to a case ID that we use in a different system.
A user can write down his capacity per week per year for a case.
multiple users can assign themselves to a case.
Users can leave messages (records) for other users to see on a case
Metadata can be attached to the case
The main problem we seem to be running into is that whenever a user tries through to edit an existing case through the overview, the case data no longer “complies” with entries elsewhere. Forcing updates through visual basic also seems to not have worked so far.
Adding to the complexity: most of the names we use are in dutch.
Here is an overview of the relations.

Here is a screenshot of the case overview as seen by a user.

Main question:
How can I make entire records change for multiple users based on the input of one user.
In compliance with the guidelines regarding asking subjective questions I’m trying to be a bit more precise here:
Additionally I’m uncertain:
whether it is our approach that is wrong,
if perhaps we’re overlooking a glaring issue, or
if we should redesign this from scratch with a different layout.
Any help specifying where we should look or what would be advisable to do would be much appreciated!
Kind regards,
Timo
Is there a quick and easy way to make a VB.NET user interface for managing the data in a normalized DataSet?
I know that is a very subjective question, so let me explain. For a brief period early in my career, I used to create user interfaces in Microsoft Access. I developed a simple, but very effective approach to user interface design. Here are some details of that approach:
Create one form per table. Put on
each form all controls necessary to
completely manage one row in the
table.
Use combo boxes for
foreign-key columns.
Give the user a
standard way to add rows and delete
rows.
Use Apply and Undo buttons.
Let
the user navigate from one row to
another with a list box.
Provide a
search box and filter options for
more efficient navigation.
Let the
user double-click on controls
representing foreign-key columns to
quickly navigate from one form to
another.
Make the state of each form
persistent (so the user always
returns to the last navigation point)
etc.
Simple, right? I found that Access encouraged this approach. It has many built-in features that make this kind of UI easy. For instance, creating a combo box to represent a foreign key relationship takes about 10 seconds.
Well, I haven't worked in Access for a while. A couple of years ago, however, I was hired to write an application in VB.NET on the NET 2.0 framework. To get a data management user interface up and running quickly, I used my Access experience to write a quick & easy prototype in Access -- that took me about one week. Then I hired a programmer to implement that same UI in VB.NET. What a nightmare! We've been working on that implementation for a year, and I'm still very unsatisfied with the results. Some of the problems we are having:
Apply and Undo buttons don't work quite right. We can't find an event that tells us when the form is "dirty" (thus making Apply and Undo relevant).
Navigation from row to row and from form to form requires surprisingly complicated code. I get the impression that we are fighting against NET's binding features, not working with them the way they were intended to be used.
The NET controls seem buggy. For instance, when the user types a value into a combo box (as opposed to choosing it from the drop down), it doesn't trigger the SelectedValueChanged event.
We seem to be repeating a lot of information. For instance, the DataSet knows there is a relationship between the columns in two tables, but we must nevertheless effectively repeat the details of that relationship when we program the combo boxes, binding, navigtation features, etc.
We still don't have good solutions for the filter and search features. There are lots of little details to work out. (For instance, what if you choose a filter that doesn't include the currently displayed row?)
We are writing many helper functions and classes to simplify the work, and I can't figure out why that effort hasn't already been done by others -- I'm certain we are reinventing the wheel.
etc.
By themselves, none of the above are a big deal -- there are effective solutions to each one. Taken together, however, these problems are making my UI development go much slower than expected.
In an ideal world, I should be able to create a small amount of code relevant to my specific data model (for instance, one user control per table establishing the layout and logic relevant to the rows in that table) then integrate that code into a template which interprets the data model and handles everything else -- navigation, adding and deleting, apply and undo, search and filter, etc.
Thus, my question: Is there anything out there which makes this type of UI development easier?
I've searched the web for various combinations of "generic forms", "UI templates", "data managment forms", etc., but I haven't found anything on topic. Perhaps I just don't know the buzzwords. Is there a specific name for this type of UI development task?
Create UCs for each table. Drop a grid control onto the UC and bind it to the tables dataset using VS's wizard. Select the options that allow for insert, update, delete. Each row on the grid will have those buttons/actions automatically added for you.
Even with the advanced technologies and available database tools (even free alternatives) are available today, it seems that huge number of users are still very comfortable in using Excel IN EVERYTHING! That's why, as a database developer working as one of these users, I am forced to let them use Excel simply because they are very comfortable using it. Especially for the older people who seemed to never gonna let Excel go and embrace a new tool.
Currently, to make their experience as smooth as possible and at the same time, automated, I'm using a lot of database queries inside Excel be it view,SQL or stored procedures. Mostly on ad-hoc (but then became permanent) reports. My question is are there any hopes to improve this situation? I'm sure a lot of organizations are using this same method. Is it possible to completely replace this arrangement with something more logical and efficient both in data collection and reliability? I'm thinking about using Sharepoint. Am I on the right track?
I have also struggled with this problem in the past and can say that what worked for me was a two pronged approach.
Step 1 – Make a good alternative
It sounds like you have already done this, depending on the system there will always be some random report that someone needs to run to suit their “Business Need”. There is no way that you could cram all of these into your system as it would fill up with reports and the users would become snow blind.
Step 2 – User education
Show them the new way of making their own reports (Business objects SSRS whatever) and make sure they are comfortable with it. This is the hardest part as some people like their comfort blanket of excel and wont want to leave it. Give them some templates and some standard reports, maybe even pair develop one or two reports at their desk with them so they get the knack of it.
I will leave on a bit of a daily WTF, there was once this expert business manager who was an expert in business objects. She made reports left right and centre but she treated it like a giant version of excel and her work was littered with examples of this i.e. one report she wrote was to get the dealing totals for a year. No problem I hear you cry just do
SELECT SUM(DealAmount) where DealDate Between X and Y
Nope not our business expert, in here excel frame of mind this was too much like black magic so what she did was return a row for EVERY SINGLE DEAL done in that year and then aggregated it client side to give her a total. In I step and wow the users by reducing this 104mb report that took 17 minutes to run down to a 100kb report that ran in about 15 seconds.
I would go the other way around. And I mean by that, not making queries and database connections within Excel, but using some sort of Web Application to let users (through wizards) generate data they need, and export them to Excel to work.
That way you will have the following benefits:
No DB connections (and probably passwords) in your Excel files
No distribution problem of Excel files with new queries, views, etc.
Centralized approach to data retrieval
Excel for users used to it
Back in the day, I loved using Crystal Reports for ad-hoc reporting. I'm not sure about it's current status, as it seems that SAP has purchased the product: http://www.sap.com/solutions/sapbusinessobjects/sap-crystal-solutions/index.epx
