Program That Creates New Objects?
Mar 30, 2012
I have a Car object that does a few things, but I need the program to create New Cars without having to write the code for every new one. Basically, the user checks some combination of Checkboxes and then pushes a button. And I need the program to create a New Car with a unique name for each combination of checked Checkboxes when the button is pushed.
For example, if Checkboxes 1,3,5 were all checked, it would create a New Car that had a different name than the New Car that is created when Checkboxes 1,2,3 are checked.
But I also need the program to be able to check when a New Car has already been assigned to some combination of checkboxes, so that it doesn't create a New Car every time that Checkbox 1,2,3 are checked and instead will use the Car that was already created.

1. Write a Visual Basic Console Application which creates two DateTime objects. One DateTime object should be used to store a value for date purchased. The second DateTime object should be used to store a value for date paid. See below for more information.2. Assign values to the two DateTime objects. See page 197 in your Doke & Williams book for help with this step.3. Use the toString method to display the two DateTime objects. See page 197 in your Doke & Williams book for help with this step.4. Compare the two dates to determine which date occurred first.

Basically the problem i have is i have made a program that creates and installs a registry key which changes default drive icons etc.
But registry key directories need double backward slashes in the directories, e.g.
What i recieve;
C:exampleicon.ico

C:\example\icon.ico
I was thinking sending the directory i recieve to another textbox and replacing '' with '\'. Is this possible?

Hi, I'm working on a program that reads text entered into a textbox and creates a list of items by separating entries by commas. Everything is working fine, except, because I am using an array to store the items in the list, I have a limited number of entries. This is only a problem because, as it is written currently, each comma counts as an individual entry. Therefore, users can enter ",,," for example, and it would use up 3 places in the array.
I'm looking for a way to check to make sure there is text after the comma before adding an entry. I've attempted to use the .substring command to check the character after, which works until it gets to the last character. Because there is no character after that, it will give an error.
Here is my code for extra clarity:
Public Class frmMain
Dim intCounter As Integer 'Stores the # of commas in the string
Dim Messages(49) As MessageProperties

I have been reading through Atheists posts in regards to client-server and TCP client/server connection's. But how do i go about writing a program with 1 client and server where the client side creates a text file.Once the server sees there is a text file it connects and downloads it to itself or the client pushes the text file to the server.Once on the server i will read the text file and put its info into a sql db.

I have a program that contains a 2d grid of panel objects and I just realized that the computer I need to run this program on does not use .Net4 and I cannot upgrade its framework either. Because of this, I have to rewrite the program in vb6, which was not so bad until I had to make the grid of panels...
Here is the code I am using in vb2010 to make the grid and I was wondering how to transcribe this into vb6.
Dim regionGrid(0 To 37, 0 To 37) As System.Windows.Forms.Panel
(in nested loop)
regionGrid(i, j) = New System.Windows.Forms.Panel()

i already finish this module but while doing 2nd module i notice that my 1st module doesnt work anymore, then i checked my code, i double click the control at design time and thats it instead it brings me to my actual code of that control, it brings me to another event, like this, this is where my original codes are placed:
Code: Private Sub lblSupplier_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)
End Sub then, after the poblem occurs, the control created another event like this:
Code:Private Sub lblSupplier_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs)
End Sub notice the difference, they are the same click event but the other one has an "_1" at the end of click.

The sample program for the Chart Control is written in C#. It provides VB snippets but there appears to be a key piece of information missing or at least hidden. Can anyone explain to me what is needed to get the Chart Control working in VB.NET VS2008 Pro?Using the Chart Controls sample, I tried to create a RangeBar. The only thing showing is a big red X across the chart. Here's the code almost exactly as taken from the VB sample:
Private Sub ChartSample()

long story short, I have created a ListView type control, using UserControls for the parent control and the ListViewItems. Most the of the control is written and works fine, right up to the point where I tried to replicate the 'Control.SelectedItems(0).Index' property and the 'SelectedIndexChanged' event.
Each child object knows its index value, and could pass this value via the SelectedIndexChanged event (assuming this is how it works in a normal ListView control -- user clicks on an item, and that item fires an event updating the selected index value in the parent object).
How does the child object raise an event in the parent object? I have a feeling this could be done with Delegates, but I'm still learning about their usage.

I am using the following code to write and empty (dummy) file to take up the remaining space on a device.RemSpace is a Public Variable declared as Long I have a function that gets the remaining space on the device and stores in the RemSpace variable (in bytes). I have tested with a msgbox to display the result of RemSpace, and it comes back correct (not 0). However, when the following code attempts to create the dummy file, the file is properly created but is only 0 bytes. What am I missing here?

I am trying to AVERAGE 6 different fields on a DataTable, but without grouping. Just the AVERAGE. I have found a couple of examples in C#, but can't find any examples for how to do this in VB.Here is what I have so far:
Dim query = From dtRow In dtIn.AsEnumerable _
Where dtRow.Field(Of String)("FOLLOWUP") = "Alert" _
Select New With { _
.Brand_Functional_Avg = XXX.Average(Function(f) f("Brand_Functional")), _
.Brand_Personal_Avg = XXX.Average(Function(f) f("Brand_Personal")) _
}
What should I use for XXX? I tried all of the options that I could think of and nothing is compiling.
Trust me, if I could write this in C#, I would, but the project requires VB.
