Create A Validator That Checks To See That If Both Players Have Entered A Nickname?
Jun 7, 2012First of all I'm trying to create a validator that checks to see that if both players have entered a nickname. If they don't then it should automatically close the form but instead the application hangs. If the first player uses three tries then it "should" automatically close. Here it is:

Making An Object Return Its Own Variable Name?
Dec 10, 2009I was wondering if there's a way I can make my objects return their own variable name as a string, something like this:
Public Class MyClass
Public ReadOnly Property VariableName() As String
Get
[Code]....
Is this possible? I'm fairly sure it should be possible through the System.Reflection namespace, but I can't figure it out.
Use ThreadPool Without Making Sub Foo(o As Object) Each Time?

VS 2008 Making A Variable An Object?
May 5, 2011excuse my coding and term limitations. I'm still learning and have only done what I'd consider basic things. I tried to search this solution for hours and but I'm coming up with nothing.
What I want to do is to reference different check boxes using one loop.
Like this..For xItemNo = 0 To 3
[Code]...
I get the error "Public member 'Checked' on type 'Boolean' not found." I get the fact I'm not able to simply make the text of the code into a variable I can easily insert into the code at will. At least not how I'm trying to do it.How can I dynamically change the check box name I'm referencing in the loop so I don't have to duplicate the code over and over for every check box name?
Class For Making Object Visible.False
Dec 21, 2011I am trying to make a customer class that will simply make a bunch of controls (hotspots) Visible value = False.

Making Multiple Copies Of A Data Bound Object From A DataGridView - How To Decouple Them
May 19, 2009I have a DataGridView object to which I've bound a list of objects (of type Asset) returned from a database query.I'm programming in VB using Visual Studio 2005.I want to grab two copies of the bound object (calling them oldAsset and newAsset) from the selected row in the DataGridView, update newAsset based on input from other controls on the form, and pass both oldAsset and newAsset to a function that will update the appropriate record in the DB.I try to grab the two copies like this:
Dim currentRow As DataGridViewRow = Me.AssetDataGridView.CurrentRow
Dim newAsset As Asset
newAsset = currentRow.DataBoundItem
[code]....
Opening a watch window on oldAsset and newAsset indicates that the appropriate values are pulled at this point. But when I try to change a property of just newAsset, like
newAsset.CurrentLocationID = cboLocations.SelectedValue
I see that the corresponding value in oldAsset is also changed. This is not what I want, but it's obviously what I'm telling the computer to do.
Designing Software - Making A MPC Sampler - Drum Machine - Making A Sound Directory ?
May 16, 2012I'm a huge music person (got my own lil record thing going) but I'm wanting to design a program that would make music in my way. I have a decent amount of background knowlege of Visual Basic and Java I'm just wondering how could I execute this whole project. The Project is making a MPC Sampler. MPC is a drum machine; a machine with buttons that once you press it that it will play a sound from a drum (ex: snare, kick, tom, ect.) . So I would want to make some pads on my program that each have their own sound. Total of 16 pads. Which the design wouldn't be hard to make nor would the functionality of it having the play back sound (in my opinoin it wouldn't be hard atleast). But the thing is I wanna map out these pads to number keys on the number pad or keyboard. I'm not so sure how to do that. But that's all the easy stuff...
Also finding information is making a sound directory. What I mean by this is that I want to make a User Interface that will open up a file directory of sounds and the user can select what "kick" or "snare" sound he may want for the kick or snare pad. I don't know how to do that or even know what to search; neverless I don't know if this whole project idea is a good idea for Visual Basic or another programing language.
Also LATER ON I am wanting to add a record and export function that alows users to..well...record and export their beat or instrumental ha. That doesn't seem too too complex (mainly due to the fact that all it needs to do is record the users key strokes and then show them and play the sounds, but obviously it would get more complex than that.)
Here is an image of one of many MPCs but one with a directory - [URL]
Flattening An Object Hierarchy Using A Shim Class - Initializing Derived Object Properties From The Base Object?
Jul 10, 2010I am somewhat new to object oriented programming and am attempting to flatten a Linq object hierarchy by using a shim class.how to initalize a derived class with property values from a base class?I have two objects, a base object with about 100 properties, and a derived object which inherits from the base object and adds a few additional properties beyond those of the base object. My simple constructor creates the derived object, but I am looking for a way to initialize the derived object properties with values from the base object.Right now I am using reflection to iterate over the properties individually and I suspect there may be a better way. The following example shows my shim class constructor for the derived class, and two properties:
newProperty1 - a new string property of the derived class
flattenedProperty2 - a new string property of the derived class, copied from a 2nd-level object of the base class
Code example:
Public Class derivedObj
Inherits baseObj
Private _newProperty1 As String[code].......
Is this the correct constructor approach to flatten the object hierarchy using a shim class? My second question relates to initialization of properties in the derived class. The constructor above creates the derived object, but what is the best way to initialize the derived object properties with values from the base object? The following code uses reflection to iterate over the properties individually, but I suspect there may be a better way.
Code example:
' property names are in the string array fieldNames
'baseObjQuery is an ienumerable of baseObj
'derivedObjList is a list of derivedObj[code].....
Is there a simple way to initialize values for the properties in the derived object based upon the values of the common properties in the base object?
