In C#, one can create an array of anonymous objects with new []. This was not supported in earlier versions of VB.NET, but a comment by Chris Dwyer in another StackOverflow post suggests to me that it might be supported in VB.NET 2010. I haven't been able to confirm this though.

I am in the process of learning LINQ to Objects. I am querying an array of reference elements using LINQ. In the code below, which I have marked with asteriks and PROBLEM, I am having difficulty returning any values for and I suspect its because of the multiple Select arguments.

I am trying to design a basic version of spaceinvaders. I have 6 pictureboxes on my form and the idea is to add a value to the picbox.top property that moves the boxes down at a certain time and speed that i have set in my timer control. The problem i have is i am trying to set properties for all the pictureboxes at the same time by using arrays.
An example would be
dim mypic() as picturebox = {pic1, pic2, pic3, pic4, pic5, pic6}
pic1.top = 10

What is the VB.NET syntax for declaring the size of an array of objects at runtime?To get an idea of what I mean, here is the code so far:
Private PipeServerThread As Thread()
Public Sub StartPipeServer(NumberOfThreads As Integer)' ??? equivalent of C#
' ??? PipeServerThread = new Thread[numberOfThreads];

I have the read the article "Creating Control Arrays in Visual Basic .NET" (link: [URL]) and I its very good and useful code for 1D array of objects. What if someone wants to make a 2D array of control objects. For example creating a "table" of 8x8 buttons that will be able to change properties by using the arrays x-y coordinates. Something like button(x,y). backcolor.black or similar.
View 3 RepliesWith the following code, I'd expect to get the array elements back that I put in. Instead, the last array element, is output three times.e workaround would be to dimension the array explicitly to hold four strings, but I used this contruct all over my VBA code and I'd rather know why it doesn't do what I expect.

This probably sounds daft, but im struggling to get to grips with Classes/Modules/arrays and objects, as well as there uses and what they are, and yes im still coding some how i hear you cry.The reason i ask is because Ive got a load of Dim's in my program that are the same giving locations of files and folders and wondered can they be used as a module that i can alter after the program is built, incase of folder locations being wrong or moved, manually correct after install.

View 15 RepliesI 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)
Problem in VisualBasic 10 on Windows 7 OS I have a form which has 30 lines for user input in format <textbox for Name> <comboBox for Type> <comboBox for Quality> <NumericUpDown for Amount> At the start of each line is a CheckBox. The intention is this enables/Disables the line. I have associated each object with an Array - eg
Dim Name(30) As Textbox
etc
and assigned
Name(1)=Name1
[code]....
ie enable/disable the boxes on a line dependent on whether CheckBox is Checked The Sub for Picked_Changed refuses to allow referenced to the arrays within, even if not generated by the picking of box (see above - it allowed '=Men3.Value' but not 'Men(3).Value', although the button sub is fine with this)
I used the tool about 3 years ago to create the classes for a webservice client to send or recieve arrays as complex data. Now i have to update these classes, since there are additional informations, that have to be exchanged. When i use the tool now with the new wsdl-files, it does'nt create the classes for complex data (structur, IGCTMObjectFactory), but only one class for simple data. In addition i have to establish a new client, that sends an array of complex data and receives another array of complex data. I tried to build the classes manually combining the client that sends an array with the client, that receives an array, but I failed.

View 4 RepliesI am working on a project which use files with a .HRZ extension. These are image files with a simple red, green, blue, red, green, blue structure. There is no header of any kind. I know how to display these files in a picturebox or convert them to a bitmap, but of course Windows 7 does NOT know what they are, so just shows a blank icon in the OpenFileDialog. How easy would it be for me to add support for this file format to Windows and/or the OpenFileDialog so I can show a thumbnail of each file? I can create my own file browser but I would really like to use the OpenFileDialog if at all possible.

I've been working on my game for a while, in a non-online multi-player state it is complete. My goal is to add LAN or Internet Play support.My game is coded in Microsoft Visual Basic 2010 Express, It relies heavily on timers.Currently you play against the AI, and there is a Local multiplayer mode, using mice, controllers or the keyboard.At the moment, it is a two player, (Or 1 player against the AI) game, from my understanding the standard Client-to-Server option wouldn't very efficent, the best choice would be a peer-to-peer system.That being said, a lot of the stuff could be done client side, like for instance, the particle engine and Dynamic Rendering.[code]

does your IDE ever get amnesia?in the line before it is clearly defined.in the following line it is not.Maybe it's a faulty translation from Tangible Software.the C example i'm looking at:
IAnimatedMeshSceneNode* newNode = (IAnimatedMeshSceneNode*) oldNode->clone();
translated as:
Dim newNode As IAnimatedMeshSceneNode = CType(oldNode.clone(), IAnimatedMeshSceneNode)
had to make a dummy for it because i can't use arrays with CType.
