Control Creates Another Same Event?
Sep 29, 2010
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.

I have been thinking about creating an event calendar. I thought through the idea of how i would attempt it, but only came up with one idea; Text files, a folder for each year, and a folder for each month.. when the user creates a new event a text file gets created in: e.g. \2010\Jan\12.txt and if another event is on that same day, the text is added into the same text file. But this leaves lost hopes for my other ideas, since it will get very complicated. Like yearly events, monthly events etc.

I created an even on a form called Sub New so I can handle some events and close the window down if there is an error.Upon doing that, I came across 3 errors that I don't know how to fix.[code] ShowDialog really isn't necessary I could just use .Show. I want to use ShowDialog because the line under those 3 shows the current form.How do I pass the date to the form?In case it's relavent, my code for sub new on frmEmail.[code]

I've read thru Iceplug's tutorial on control arrays and got it working. I tried to add a new event by basically copying his click event code and calling it a doubleclick event. I used the proper addhandler and assigned the correct name to my sub. I have the click event changing the background color to blue and the doubleclick event changing the background color to green. The background color does not change to green. Why?
Heres the tutorial with my new code encased in asterisks ...
Code:
Imports System
Imports System.Windows.Forms
Public Class form1

How should I go about getting my mouse position over multiple controls, and such. I can't use the form_mouse move event, or any other control event nor can I use them all at the same time cause that would conflict with the actual position I need for an object.

The panel has a click event which shows a message saying "HI"
when the panel is behind the wmp control the message is not shown when i click on it.
so the question is is there a way round it, cos currently it only works if the panel is on top of the wmp control

But i dunno how to call the click event.

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.

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.

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()
' Populate series data
chrtTCP.Series.Add("Tasks")

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.

I am attempting to keep user inputs into our application as clean as possible. One way I am attempting to do this is not allowing incorrect data type in fields (not allowing alpha characters when expecting numeric values)I found and implemented the following code:
Private Sub txtSocial_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles txtSocial.KeyPress
Dim UserKeyPress As Char = e.KeyChar
Dim isKey As Boolean = e.KeyChar.IsDigit(UserKeyPress)

I need to create an application that creates Pascal's triangle the user would enter the number of rows, and using the formula (which i do not know... :/) would create the triangle. For example: the user enters 5 rows
triangle:
1
1 1
1 2 1
1 3 3 1
1 4 6 4 1
as you can see the numbers are created by adding the 2 numbers above it starting with 1 at the top
