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?

View 1 RepliesIn the following LINQ query, i would like when the Loc=Locale.Gr all the records with GrID=100 returned and when the Loc is anything else all the other records with GrID <> 100 returned.How can i achieve this one? I tried something like the following, but it is totally wrong.
PrivateSub Test(Byval Loc as Locale)
Private Const GrID as integer = 100
Dim Query = From c In Mob Where c.CountryID = IIf(Loc = Locale.Gr, GrID, <> GrID) select c

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.

View 1 RepliesThe idea is to scan a folder of images and then let the user navigate back and forth through the images using a couple of buttons.The problem is, I can only get it to return a single image, and not the whole lot. It's looks to me as though the images are getting assigned to the same index in the array. [code]

View 3 RepliesThe app i am working on is for creating theme for the iPod touch... It has to deal with LOTS of images (100's potentially) There will be the set of default images, and then the user created replacement images. I started loading all the defaults into a resx file... thinking then I could just pull them out. now that I started setting the default, this sucks! lol the app will do this, on load it will set all the images (variables) to the resx images then when a theme is loaded, it will replace the default with the user image (if the user img exists) otherwise, the default stays. Then the "screen" is drawn to show the user. so, here is just the images to build the wallpaper, dock, and status bar...

I was thinking to make an app to save images [or download images] to local hard disk. But to keep it easy, I want this app to create a small picturebox on form to show the thumbnail of downloaded image. Lets say a 5 pictureboxes has to be added with the thumbnails to show the recent downloads. A user can save the location where he wants to save the files on hard disk. A listbox or a dropdown menu will help in categorizing the images, like image1 in friends section, image2 in family section, image3 in others, etc... When the program restarts all the latest 5 thumbnails has to be loaded in pictureboxes and the directory that was chosen. Finally, a button that shows the downloaded images into original image file size one by one or a slide show. Is it possible to make such program?

View 2 RepliesYesterday I asked why a adding 10 times 0.10 to a double is not equal to int 1;in VB Why (1 = 1) is False.I got an excellent answer. The overview is because:Floating point types and integer types cannot be compared directly, as their binary representations are different.The result of adding 0.1 ten times as a floating point type may well be a value that is close to 1, but not exactly.I can see the reason why now. However, if I do something like:[code]In this case I really obtain equality between double 1.0 and int 1. I thought then that double were only approximations so I would expect d to be somehow a value close to 1 as in the original first question. Why is not a good idea to compare directly different data types (in this case double - integer) and why I this time I obtain equality ??

I'm a little foggy on System.Type versus an actual class type (like Object or XmlDocument) in .NET... will this code correctly determine if the type of a particular object is equal to a class I specify?
// Given "myObject" (unknown type), and some class type (let's say "MyClass")...
If myObject.GetType.Equals(MyClass)
If TypeOf(myObject) Is MyClass[code].....
Which one is correct? Bonus points if you can provide some information on what a class identifier is versus what a System.Type is. :)
Note: The language doesn't matter here, VB.NET or C# is fine, the code above is pseudocode.

Why does the first if statement evaluate to true? I know if I use "is" instead of "=" then it won't evaluate to true. If I replace String.Empty with "Foo" it doesn't evaluate to true. Both String.Empty and "Foo" have the same type of String, so why does one evaluate to true and the other doesn't?
//this evaluates to true

This makes no since to me I have a textbox that the user will put in information that I need to cut off so I wrote this code
txtMatID.Text = Trim(Mid(txtMatID.Text, 1, (InStr(txtMatID.Text,
"-") - 1)))
The user will imput a number value then a - then some words after that. I just want the number value. But when I try to debug the app it breaks on this line of code with this error. Argument 'Length' must be greater or equal to zero.
In my decryption statement I am getting
Argument 'Length' must be greater or equal to zero. is this statement wrong
