Changing The Position Of A Form, Pixel By Pixel?
Jul 20, 2009during the development of my project, i've fall in the need to change the position of some forms, pixel by pixel using a timer.Now, i've checked that the movement is very fluid when form is not very heavy, when it contains few elements, but when it has a lot of elements inside, the movement becames nervous and not fluid, the movement becomes jerky.

For some reason the resize event is only triggered once and only the width gets set. If I change the order only the height gets set. how to make it change both?Actually I wouldn't ever need to change both if not for a small but annoying little problem on normalising. Rather than fit the available screen height it always seems to be a bit more, as if the top border height is added to the existing max height. This seems to be a .NET bug.

Load A GIF File, And Start With The First Pixel And Check To See If That Pixel Color Is Closer To Black, Red, Green Or Yellow?
Jan 30, 2009I would like to load a GIF file, and start with the first pixel and check to see if that pixel color is closer to Black, Red, Green or Yellow, then take what ever color it closest matched to and output that color as a number, 0, 1, 2 or 3. So just for a small example a 5x4 GIF would be converted to something like this: 0112223322220111332?

Dimension Of Variable Inside For Loop
Mar 30, 2010Using VB.NET .NetFramwork 3.5. This fails and strikes me as odd. Is this correct behavior:
Public Sub TestForEach()
For index As Integer = 1 To 10
Dim z As Integer
Assert.AreEqual(0, z)
z = index
Next
End Sub
I would expect z to always equal 0 as I thought the dim-ing of an integer would set the value to 0. If you run this. It fails at the second loop. For some reason z retains it's value of 1. I know I can manually initialize z to = 0, but I wanted to know if this is a bug or expected behavior.

I believe that I need to create some sort of looping structure that will search through each row of the array.I have created a listbox that will allow the user to pick which row of the array the program will search.This is what I have created so far, but I am only just learning and I am having trouble wrapping my head around how arrays work. So I'm not sure if I am on the right path or not.

Returning New Array Dimension From Within Function
Jun 22, 2011I'm trying to return changes to array data, including redimensioned arrays, from within a function call in code similar to:
fault = MyFunction(Array1, Array2)
Public Function MyFunction(ByVal inObj1 as UserStruture(), ByVal inObj2 and Integer(,)) as String
Dim myResult as String = "Failed"
Dim tmpStruct() as UserStructure = inObj1
[Code] .....
This works fine in updating the input array 'Array1', only when the redimensioning of tmpStruct is NOT performed. After redimensioning tmpStruct, the redimensioned array is passed back successfully into 'inObj1' within the function 'MyFunction', but is not passed out of the function call; i.e.
fault = MyFunction(Array1, Array2) -
The dimension of array 'Array1' out of the function call remains as it was before the function call. However, the data change; i.e.
tmpStruct(0).Nam = "New Name"
is passed successfully out of the function call.
Why the Redim operation is not passed back out of such function calls. I would like to return changes to arrays 'Array1' and 'Array2', plus a result string from the function call if I can. Furthermore, I would also like to change the dimension of the array within the function call, if required, and return the complete redimensioned array back out of the function call.

Storing 2-Dimension Arrays In My.Settings?
Dec 7, 2011I'm still doing upgrades on my program that i'm creating and i've run into a bump again. I'm currently using a multi-dimension array to store a name, email, password, email provider, and user name. These 5 values are stored, corresponding with the latter, meaning the array is build as: name 1....n user name 1....n user email 1....n user email provider 1....n password 1....n So my question is, how can i store this in My.Settings? To be clearer, i'll use code: My.Settings.Name = name My.Settings.UserName = userName etc..... My current set up for a first run is like so... My.Settings.Password = adminInfo(2, 0) My.Settings.UserName = admingInfo(1, 0) etc.

The problem I'm having is while trying to find all Measure Groups that are related to a given Dimension. I've been digging through the API and it doesn't seem that Dimensions have any information on Measure Groups at all, but Measure Groups can contain Dimensions.
This makes it easy if I want to get a list of related Dimensions given a Measure Group(measureGroup.Dimensions), but what I'm looking for is the opposite.
The only thing I can think of is to loop through all the Measure Groups within the Cube and check if it contains a reference to the Dimension in question[code]...

tmpArrayX.Add(field(0))
tmpArrayX.Add(field(1))
