Checking For Date Overlap Across Multiple Date Range Objects?

Nov 7, 2011

I have several records in a database that have Start and End Dates

09/15/2011 - 09/30/2011
10/15/2011 - 10/22/2011
11/01/2011 - 11/15/2011

When user stores a record, I need to make sure dates don't overlap.My simple code checks date ranges within a specific record (e.g. user enters 9/16/2011 or 10/21/2011, I throw an exception.)But, on the slim chance a user gets creative (e.g. 10/14/2011 - 10/23/2011 or even 10/14/2011 to 11/16/2011), now they have circumvented my check.BTW, the user could enter 10/14/2011 to 10/23/2011 if they were editing the record that contained values 10/15/2011 - 10/22/2011.So, I'm trying to solve this riddle with a linq query. However, what I have isn't working exactly right.

UPDATE Nevermind about code not working. While trying to provide an example to expand on Miika's repsonse, I found my answer. So, giving credit to Miika for pointing me in the right direction and posting my working code below:

Here's my code:

Private Sub CheckForOverlap(myMonth As Messages.MyMonth)
Dim am As New MyMonth()
Dim amCollection As Messages.MyMonthCollection

.net - One Dataset With Multiple Results Sets (multiple Select Statements) SQL Reporting Service?

Oct 15, 2011

I have a question regarding the dataset usage in Reporting Services. I have a stored procedure which returns multiple select statements (result tables), and I created a Dataset in Reporting Services 2005 with this stored procedure. The problem is that I can not reference the second or third result table, and I can only use the first select statement fields. Is this the limitation on Reporting Services Dataset or is there a way to use multiple table results in one dataset?

Multiple Checkboxes With Apply Button?

Aug 31, 2009

I am working on a program that has about 20 checkboxes on it.What I want to be able to do is to check the checkboxes and then hit an apply button then at that point whatever is checked/ or if something is unchecked the code for that item is run and those changes are applied. If the box is checked it disables the service if it is unchecked it enables the service.

the code I have so far is this for each service I want turned off i have placed under a button name Apply.Each service is a different registry entry and service name, some are just registry key changes.the code seemed to work at first but that is when I only had one checkbox under the button.

I know I have done something wrong with the program logic here Im just not sure how to fix it as I've only been using VB.net for 2 weeks now. I can't find any reference on the internet to having multiple checkboxes with an apply type button.

VS 2008 Getting Total From Multiple Checkboxes?

Dec 8, 2009

I'm working on a school project and need some help getting pointed in the right direction. The project is a lawn care application with 2 forms in which the user can select different services they want for their lawn. On Form1 I have 3 checkboxes the user can select: mowCheckBox , fertilizeCheckBox , and mulchCheckbox each with a different price. And nextButton to navigate user to Form2

On Form2 I have a listbox which shows the services the user selected, a totalLabel which will show the total dollar amount of the services, and a calcButton to calculate the total dollar amount.

The problem that I am having is being able to get the total dollar amount. If the user selects the mowCheckBox ($25) and the fertilizeCheckBox ($20) in Form1 I need the totalLabel in Form2 to show the total but cant figure out how to??

Public Class Form1

I have a group box which contains 40 checkboxes, when a checkbox is selected its content is added to a list and removed if already checked. Now I could write 40 functions one for each event (lots of code) each containing a add to the list function and a remove on uncheck, or I could use multiple handles (confusing multiple line declaration) is there another way? say my list of chkboxes had 100 checkboxes or more? can I for example use the container in some way?

VS 2005 : Multiple Checkboxes With Apply Button?

Aug 10, 2009

What I have is approximately 20 checkboxes each one executes the following code below... They do start and stop the service. I also have another 10 checkboxes that make various changes to the registry however there are several issues I am having.....

1. I can set the registry value but I need to get a registry value to see if it is set to 1 or 0 or another number, if that registry value returns as the 0 then the checkbox would be unchecked if the registry if it is set to 1 then the box would be checked (this is an example) however it would be testing for a number condition not a string.

2. The changes happen immediately however if you check a box to stop a service then immediately uncheck it the registry key is changed but the service is not started. What I want to do to resolve this is put an apply button in that would allow multiple variations of checkboxes to be selected, it would show the current state of them and then once changes are made the apply button can be hit it will apply the changes only then and not before then. I also need to have a way where if something is changed and applied the program verifies the service fully started or stopped.

3. I also want to setup several other buttons that will run only predetermined checkboxes

4. I want to be able to also save the checkbox configuration as like a setting that can be loaded in a button called custom.

the problem with this code is that it only inserts the serial number of the LAST checked checkbox and the number of entries of it depends on the number of checked checkbox for example ... if I checked the rows with the serialnumber 123 and 55652341, first the row with the serial number 123 then second 55652341, only 55652341 appears in the database and it is entered twice(twice because two checkboxes are checked)

.net - Get INotifyPropertyChanged On Multiple Inherited Objects?

Sep 2, 2011

I have a class, Vehicle. I created two child classes, Car and Plane. I want to monitor the speed, which is a Vehicle Property, and bind it to a control (label, or image, for example) in WPF. When i create a static Class which only purpose is watching the Speed Property, it works, as far as the INotifyPropertyChanged is declared with the Speed Property name.

But the problem is, I have to create dynamicly multiple Cars and Planes by looking in an XML file and deserializing my objects, and creating multiple Car or Plane UserControl (Let's not discuss this way of working, please). So I have to get the Speed property inside the Vehicle Class (which is normal), and I have to get a INotifyPropertyChanged on each Speed of each Vehicle Created. So, my Cars and Planes are loaded, and I have to get all speeds, but I can't create a static Speed property by Vehicle. By the way, by creating a non-static Speed property (as int, for example) in Vehicle Class with INotifyPropertyChanged raised in the setter, it does not work. The event seems to be raised, but my converter is not fired, and my controls does not update.

In my Vehicle Class

Private SpeedValue As Integer
<XmlIgnore()>
Public Property Speed() As Short
Get

[Code]....

The PlaneView Class is almost the same for this part.

I confirm that the converter is fired just once, the first time, when the tabs are created, because I put a breakpoint on the Convert function definition. After that, the converter is never fired again. So the picture img_fonctionnement is displayed, but it is never updated. But the Speed property is updated, I swear. And the INotifyPropertyChanged (in Speed's setter) is raised, as far as i know with the help of the debugger.

And the "an item with the same key has already been added" (which appears in a messageBox, and not as an exception) seems to appear only when I am to long with the debugger. In normal execution mode, it never shows.

With BtnLoad            .ForeColor = Color.White            .BackColor = Color.IndianRed        End With

it works fine. I have so many objects though, I don't really want to copy and paste this with statement 50 times. is there a way to make a with statement take multiple objects?

VS 2008 (De)Serializing Multiple Objects Into One File

Dec 21, 2009

I am trying to create a load and save function for my customizable Menu/Tool/StatusStrip controls (see signature). Those three controls use a single AppearanceControl class, which is mainly just a large list of properties (Colors) which control the colors of the Menu/Tool/StatusStrip.

I want to be able to save and load the values of these properties so the user can store them and load others with ease. Serialization seemed the obvious answer, although I never used it before.

Now, there is a slight problem that I cannot serialize Colors, so I simply gave each Color property the XmlIgnore attribute, and created an Integer property that gets and sets the Color property (using Color.ToArgb and Color.FromArgb). This way I can serialize the color properties succesfully.

Then, there is another problem. The properties are not all in the AppearanceControl class. Instead, the AppearanceControl class has a large number of subclasses, which in turn contain the color properties.

As a small example, I may have this:

vb.net
Public Class AppearanceControl
Private _toolStripColorProperties As ToolStripColorProperties
Private _menuStripColorProperties As MenuStripColorProperties

Control Arrays - Allocating Multiple Camera Objects Dynamically

Jan 19, 2009

I have a VB.NET application and use some third party (closed source) ActiveX controls. One of the controls represents a "camera" (connected over several interfaces) and I try to write an example how to work with several cameras in one application. To do this I allocate multiple "camera" objects dynamically as an array which works as expected like this:

Const NUM_CAMERAS = 2
Private MyCameras(NUM_CAMERAS ) As xxx.MCamera

But the camera objects needs to be allocated with WithEvents because they raise events when a new image was taken. I found out that WithEvents variables cannot be typed as arrays and this is a pretty common problem so I also found some workarounds: [URL]. This is already pretty good and I adopted this to my concept. So I have a MyCameras array and a MyCamera all "without Events", first allocate a new MyCamera object, add a event handler and then put it into the array.

Unfortunately I get an error when calling
AddHandler Camera.ProcessModifiedImage, AddressOf MyHook

Normally "MyHook" is declared as
Private Sub MyHook (ByVal sender As Object, ByVal ModifiedBuffer As xxx.ProcessModifiedImageEvent) Handles Camera.ProcessModifiedImage

Like in the "Button examples" I just removed the "Handles Camera.ProcessModifiedImage" but I get an error that "MyHook" has not the same signature as the Delegate
Delegate Sub ICameraEvents_ProcessModifiedImageEventHandler(ImageIndex as Integer)
