WPF Hit Testing UserControl And Geometry?
May 3, 2012
I'm trying to make hit testing work between one user control and another user control. I was looking at other questions and found that I have to put this in my user control.
Protected Overrides Function HitTestCore(hitTestParameters As System.Windows.Media.PointHitTestParameters) As System.Windows.Media.HitTestResult
Return New PointHitTestResult(Me, hitTestParameters.HitPoint)
End Function
I also have a filter which correctly shows the controls I want to hit-test somehow the htcallback isn't working.
Because I can't hit-test with my user control, I made a rectangle on the same spot and use that in my hit test. This doesn't seem to be working.
Dim hitTestGeometry = New RectangleGeometry()
hitTestGeometry.Rect = New Rect(_selected.breedte, _selected.hoogte, Canvas.GetLeft(_selected), Canvas.GetTop(_selected))
[Code]....
if you want to hit-test against geometry you need to override that second overload as well

Our VB.NET project is using a Java library from Vivid Solutoins [URL}... to do Geometry calculations.[URL}...
What I can't figure out are the units specifically for the Buffer property, or any other distance for that matter. My program is dealing with Nautical Miles, and the documentation gives no indication if the units are degrees, miles, Nautical Miles, Kilometers, inches, etc.

I'm looking into adding some unit tests for some classes in my data access layer and I'm looking at an update routine that has no return value.It simply updates a row based on the id you provide at whichever column name you provide.Inside of this method, we collect the parameters and pass them to a helper routine which calls the stored procedure to update the table.Is there a recommended approach for how to do unit testing in such a scenario?

I'm building an Active Directory wrapper in VBNET 2.0 (can't use later .NET) in which I have the following:
IUtilisateur
IGroupe
IUniteOrganisation
These interfaces are implemented in internal classes (Friend in VBNET), so that I want to implement a façade in order to instiate each of the interfaces with their internal classes. This will allow the architecture a better flexibility, etc.Now, I want to test these classes (Utilisateur, Groupe, UniteOrganisation) in a different project within the same solution. However, these classes are internal. I would like to be able to instantiate them without going through my façade, but only for these tests, nothing more.

I have a Windows Form frmMain() holding seven more-or-less unrelated UserControls, ucFlopsy", "ucMopsy", "ucCottontail", etc...I say "more-or-less" because each of the seven UC has three similar public read/write properties:
IsLocked (a boolean indicating if the following two properties are "Locked")
IsLockedID (if IsLocked=True then IsLockedID is an integer)
IsLockedName (if IsLocked=True then IsLockedName is a string)

I have a Windows Form that contains a custom control container as a UserControl. For the sake of this question, this custom control container is called Dashboard. This container called Dashboard contains numerous other controls depending on their permissions. I need to raise events that are contained on these controls through the Dashboard control and over to the Windows Form.
How can I bubble up the event? I'm using VB.NET for this project, but can convert C# into VB.NET.Also, to complicate matters, the main Windows Form is a VB6 project. So, I'm using the InteropFormsToolkit to accomplish this.

I have two UserControls on a MasterPage. DataEntryUC contains several TextBoxes and DropDownList. NavSaveUC contains navigation buttons. When the user clicks on a navigation button, I will be saving the data entered into DataEntryUC from the NavSaveUC UserControl.
I have a couple of tables in my DB that contain stored procedure names, control names, control types, SqlDbTypes, etc.... that correlate with DataEntryUC.
How do I reference a text box that is on DataEntryUC from NavSaveUC?
I have been working on the following code from NavSaveUC with no luck.
Dim MyControlName = "txtFirstName"
Dim MyControlType = "TextBox"
Dim MyStringValue as String

I have a usercontrol that has a main form and calls another form within the usercontrol to get some data from a database that allows the user to select some items from a CheckedListBox control on the sub form. I want to pass the selected items from the CheckedListBox back to the main form and display the results there. I have a public property called DBList of type List(of String) on the main user control. If I create a reference to the usercontrol form the second form within the usercontrol I get a new instance of a user control. All I want to do is set the property on the usercontrol and close the secondary form. How do I reference the usercontrol from the form within the usercontrol?
Code in UserControl:
Public Property DBItems() As List(Of String)
Get
Return DBItems

I just discovered the joys of UserControl's and I was wondering if it is possible to populate the usercontrol with data from a database in the UserControl's Form.Load event instead of the form the userControl is placed on. I feel it would make using the control a lot easier if it just populated itself without anymore code.I tried it with a ListView but it gave me a bunch of errors, so I didn't know if it had to be done a certain way or if it was just one of those things that doesn't work no matter what.

I have a Do loop that I want to exit once it goes through without making any changes to an object I created. I figured the best way to do this was to create a temporary copy of the object at the beginning of the loop and then compare that to the actual object at the end of the loop to determine whether any changes were made to it. The problem occurs when variables are accessed and copied by reference. I have tried to use some of the methods such as .Clone and .Equals (maybe I shouldn't be using these, but I didn't see any better built-in methods), but I seem to be doing some stuff wrong. Can somebody give me an example of a good way to copy an object for later equality testing, and how to do the equality testing?

I was once a VB 6 expert, but it's been a while.I am attempting to create a simple DLL in VB. I created a new WCF Service Library, which is what it looks like I needed to do. I filled out the interface and implemented it. Here's the interface:
<ServiceContract()>
Public Interface AgileApi
<OperationContract()>
[code]....
And attempted to call it, but I get System.EntryPointNotFoundException. I've tried pathing the defined library and copying the dll file into the same place where my EXE is, but no change to the error.

I'm trying to determine if a file "G:myfilesfile1.txt" exists. Using sample code from numerous web searches I can't make any of the FileSystemObjects work. Seems to me the FSO routines are an add-in to VB. If this is so, how do I add them in?
In noncode, this is what I really want to do:
if "file1.txt" exists AND "file2.txt" exists
if "file1.txt" filedate > "file2.txt" filedate
copy "file2.txt" to "fileold.txt"

when I try to test for a null value using the following:
If not string.isnullorempty(trvlitreadservice.itineraryinfo.reservationitems(zbook).value) then .........
I get an error as soon as it hits a null value. I thought this was supposed to test for a null value yet it throws an error for the very thing I'm testing for.

Now, If I want to run a test using "Todays" Date using FitNesse, What would be the easiest way of creating a way to have (OurService).CurrentDate be static? We have a control that ads Days,Years, or Months to the current date.. and I would like to be able to test this.

I am responsible for rewriting an internal tool for my company. I am currently reworking the most time consuming step to run faster which should give me time to re-think the design of the application for a full rewrite as the interstitial version will meet the current needs. I really want to take this opportunity to implement this code using BDD/TDD but I am new to this method of programming in general and especially within the context of .NET. Are there BDD/TDD tools available for .NET? What resources should I look at?

I often get calls from a friend of mine's company saying "ahhh our email is not working!". I thought I could write a program that would test a few things that they could run and have easy answers to my questions when they call. Things like "Is your internet connection alive?", "can you send mail but not receive it?", etc.

I have created a COM callable assembly which consists of an Interface, a single class which implements the interface. In this case the implementation is a single method.I have registered the assembly, created a type library and added the assembly to the GAC.I thought about opening an Office application like WORD or EXCEL 2003 and trying it from there but beyong referencing the COM assembly I have no idea how to code it.

I have a windows form application that connects to an access database. When the program is running it connects to the database and populates several textboxes that are bound to the dataset. I have been researching for 2 days and cannot find exactly what..I need, although a few threads have given me a better insight into my dataset. I would like to type text into a textbox that is bound to the primary key and when I tab out of the textbox (lostfocus event) have the program do a quick search of all records in the dataset of the primary key and if a duplicate exists, msgbox the user that that particular text is a duplicate and is not allowed, however if the text is not a duplicate, continue the tab keystroke allowing the cursor to move to the next textbox bound to the database.
