VS 2010 Program To Output A String, Based On Each Value Not Selected
Jun 7, 2012
I have 12 Boolean values in an array. Each of these values represent a CheckBox in my application. I want my program to output a string, based on each value not selected. Each of these values will have a predetermined string that is different from the CheckBox's caption and will be joined to create a final string. I want to generate all the possible combinations for when there are 1, 2, 3, 4 and so on up to 12 of these options at once. I can better explain my problem through the repetitiveness of the code below.

I have a weird requirement to parse a file which is a comma separated string with repeating header..i have a file which i load into database and this gets populated as a single column string with header and details data:something like this (This is single COLUMN String in a table). SSIS is not able to handle this so i am trying to know..If it is possible using writhing VB.Net custom component.[code]Also, if i can pass the values of header (i.e. header3, header5, header7 and header10) as a variable would be ideal.

I'm getting lat/long values output like: {Lat=51,2833333, Lng=3,45}How do I change the output to 51.2833333 - 3.45 or 51.2833333, 3.45
txt_converted.Text = txt_converted.Text & LatLong.ToString & vbNewLine
The "LatLong.ToString" holds the value/output.

I am working on a program where a user either enters "small" or "large" and then the number of toppings. Once the user has done that my program outputs the total cost of a pizza based on user input.
My problem is no matter if I enter LARGE or SMALL into the textbox for size of pizza the output displays "A small pizza with 2 toppings cost: $x.xx"
It also displays the price of the pizza as a small one. So somewhere along the lines it changes everything to be small.
this problem only started occurring after I made this procedure.
Procedure that I believe is causing problem
Function IisUserInputValidSizeOfPizza(ByRef mytextbox As TextBox, _
ByRef errorMessage As String) As Boolean

So I got this program to generate me some data and I want to show that data to a label.
If I don't do a display I can generate about 20,000 data per second, but if I do, I get about ~9,000 data per second.
PS. Since the generating logic in is a thread, I have a function that does the displaying to the label.

The following output produces a string with no closing xml tag. m_rFlight.Layout = m_rFlight.Layout + "<G3Grid:Spots>" + Me.gvwSpots.LayoutToString() + "</G3Grid:Spots>"
This following code works correctly
m_rFlight.Layout = m_rFlight.Layout + "<G3Grid:Spots>" + Me.gvwSpots.LayoutToString()
m_rFlight.Layout = m_rFlight.Layout + "</G3Grid:Spots>" 'add closing tag
What's going on here, what's the reason the first example isnt working and the second is?
The gvwSpots.LayoutToString() function returns a string.

I need to remove an instance in a class for which I also created a dictionary with a string key type. Like this...:
vb
'Declare dictionary
Public PersonsList As New Dictionary(Of String, Person)
'At the bottom of frmMain.vb
[code]....
As you see, I end having 120 instances of the class Person, each assigned with a string key consisting in "student1" to "student120".
At other parts of the program I repeatedly refer to PersonsList("student" & n) to set values at those class entries, mainly with a For n ... Next block.
Now... I need a routine to remove one of those instances for good, including its entry at the dictionary, so my first bet is this...:
vb
Public Sub ExpellStudent(ByVal student_index As Integer)
PersonsList.Remove("student" & selected_student_index)
students_count -= 1
End Sub
I assume this is good enough to remove the KVP at the dictionary AND the class instance proper... right?Well, even if that is ok, I foresee one problem... Let's say I removed "student46". Next time I run a For n = 1 to students_count I would bet that I'll receive an exception due to having a gap at "student46" KVP... and that without saying that students_count will be 119, so it will never reach "student120".In short, I need a way to reassign the KVP of the now 119 Person entries, so they're consecutive again (I don't care about them changing their string key values), so I still could use my For n = 1 to students_count ... Next blocks without problems... but I cannot figure out how.

I have to display the available times in a dropdownlist called "DDL_avalTime" based on the date selected in a ASP calendar.
How the program works is that when a User clicks a date form the caldendar, it checks the SQL database. In this case the table that I'm retrieving it from is "trainerbookings" from the column "trainingDateTime". The data type for this column is datetime.[code]...

I want to populate the combobox based on the selected item in the first combobox. The following code is written in vb.net 2008
Public Class Form1 Sub fillcombo()
strsql = "select * from device"
Dim cmd As New OleDb.OleDbCommand
cmd.CommandText = strsql
cmd.Connection = con
[Code] .....
For this code I am able to populate the first combobox and when I select the specific item in combobox then the second combobox shows only the first element of that item.
In MS access 2007 I have created 2 tables:
1) Contains the device ex:computer
2) Contains the device and its parts ex: cpu, monitor so here the device has duplicate values
Table names are device and parts.

I have a vb .NET 2005 form that needs to load data based on a selected month by the user. Because there is a large amount of data in the table (60k+ records per month) it is taking the query a long time to pull the dataset back and populate the form. how I can decrease the overhead associated with querying a large dataset to populate a base form?
Note, I have created an identity key on the main table but haven't yet indexed any other fields (Though I could use some suggestions on how I should index).
See the following example of the Stored Proc that is run before my .net form is launched:
Dim cmd2 As New SqlCommand
Dim ConnectionString As String
Dim TheDatabase As System.Data.SqlClient.SqlConnection
