I am trying to reset all integer values to "0" with a reset button.I try not to use hardcoding by simply set them one by one. So my idea was checking all the variable's type and set them all to "0".
I tried to use this methode, from someone in this forum (sorry, I forgot the name but this is very helpful...) For Each ctrl As Control In Me.GroupBox4.Controls 'Check and see if this control is a TextBox
If Object.ReferenceEquals(ctrl.GetType(), GetType(Label)) Then 'Check and make sure this s the "TextBoxToExclude"
'CType(ctrl, CheckBox).Checked = False
CType(ctrl, Label).BackColor = InactiveColor
End If
Next
But when I tried to find the code, I couldn't get it.So, if anyone knows how to do this,
It's good to be back in this forum again hoping someone could help me solve my problem again xD My goal is to import .txt to db.
This is my code

Some of the records are inserted but when the code read the part where there is an empty/null value in the column where they are assigned as "decimal" the error message "Error converting data type nvarchar to numeric." pops out.
In the following code I have two class scoped variables intCompanyID and intEmployeeID. When I set them to a value in btnFetch_Click then try to read them later in btnSubmit_Click they are set to zero.

how can I set the size of my integer array if it is determined at compile time?

I have a program that calculates values of a function, say f, with respect to another variable, say L.I have an array of f(L), for L going from 0 to a given integer value, say t-1 in steps of a value i.I need to export the values of this function to an Excel spreadsheet in a given column, and to do this, I would like to re-index the function f, since i is much less than one, and so the following loop I use (see below) won't work:
For L = 0 To t - 1 Step i Sheet.Cells(L, 1) = L Sheet.Cells(L + 1, 2) = f(L) Next L
The first code in the loop will essentially load the values of L itself, at which the function is defined and calculated, and the next line will load the values of the function at each value of L.Since the indexes of the row and columns in an excel spreadsheet only go in steps of 1, I need to convert the indexes of the function, or the indexes to which L is loaded, so that it would be scaled so that the first entry corresponds to L=0, but the next is L=i, but loaded into row number 2, etc.
I'm trying to set an Integer value from my.settings.The values comes frpm a listbox, and then inserted to settings (set to specialized.StringCollection)The problem is when i'm trying to get the values and apply them to my function.Error code: Conversion from string "65 & 71" to type 'Integer' is not valid.To me it looks right, but maybe i'm missing something.

I have a repeater which displays products. Users can select a Size - dropdownlist and an Amount - textbox. Then they press Order or Cancel. When they press Cancel I would like the values of Size and Amount to return to their default values. Protected Sub lbtnCancel_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles lbtnCancel.Click rpt.ProductList is the repeater name lblFeedback.Text = ("") lblFeedback.ForeColor = Drawing.Color.Black End Sub I am using VB.NET.
I can't seem to get this code to refill the chart with new dat. The first time it executes, all is great, but when I change the year(numericupdown1.value) it adds a new set of data points instead of re-plotting the original set.

i have a textbox with hexadecimal values and i would like to use the slidebar/scrollbar to change the values (increase/decrease) then save the final values to a text file. To prevent the program from writing to many times to the file, i decided to use a timer. As long as the user still making changes or controlling the slide/scroll bar the timer will re-load (5 seconds). When the user is done modifying (no more dragging or clicking on the arrows) at that time the timer already expired, then the value get recorded to the text file.
How do I reset My.Settings at run time to the initial default values. I want to do this after the app has been running and the user may have save changed settings. The intention is to reset evering to 'factory defaults' as opposed to the last saved value as done by 'settings.reload'.For example in the property below , I want to restore to the value to '90' as given in the default value. I want to do this for all settings.[code]...
I'm working on a simple BlackJack (player vs dealer) system, that I plan on making gradually more advanced. However, while everything works brilliant, I'm yet to find a logical solution to declaring an Ace as both 1 and 11.So my question is, how do I pull this off. Below is the "New Game" logic (code) so it should give you an idea of what I'm working with (note how player scores are added together, I'm sure it's easy enough to understand...).I'd like lblPlayersum to still be a usable integer, though I'll rework everything if noone has a logical solution.Just quickly note that the "Cards" array is purely used to coordinate images."CardsVal" coordinates that values within the deck. Arrays 48, 49, 50 and 51 are the aces. (Currently defaulted to 11).[code]
I have a question, that is: What is the easiest way to get Integer values from a file.The file is structured like this: (Without the text)10...How many values are in the file 1 2 3 4 5 6 7 8 9 10..The values...I know how to do it, the hard way, but I need an easier way, to teach a friend the basics of Vb.net.
My problem is that I have two forms, Form1 and Form2 ...on Form1 there is a TextBox called txtTotal (this contains the calculation of Ticket Prices, thus it's a numeric value) and on Form2 there is a TextBox called txtTotal2. All I want to do is get the same number that appears in txtTotal on Form1 to appear in txtTotal2 on Form2 .However whenever I try some of the help tips online such as using a declaring txtTotal as global or friend it dosn't work, and any other code iv tried attempts pass the textbox value as String which brings an error.
Ok, so I am building my own program to control a video player I have through telnet, I have everything else working except one thing.I have a reset button to reset the player, when I press it, it sends the string "Reset" and the unit resets without a problem.But when I add a code to close the winsock connection upon reset, it doesn't send the string to the unit. I am sure what is happening is the winsock is getting closed at the exact same time it is trying to send the string and so it fails to send, how do I make it close winsock AFTER the string has been sent? [code]
I am working with a future value application and I am trying to display the calculated future values in a listbox. For instance, I input the monthly investment, the yearly interest rate and the number of years into textboxes and I want the application to list out the future value for each year until the number of years in which I entered is reached. I cannot figure out how to get the code to display the value after each year. I am trying to use the "mod" operator to display the value each time the 12th month comes around.[code]...
i am having trouble displaying the values i get from an IList(Of T) and displaying that in a listbox found on another form. I have used a for loop to get the values from the IList, then i can display that in a msgbox. for eg:
Dim j As Integer Dim path As String = "" For j = 0 To best_tour.Count - 1
[code]....
best_tour is ot type IList() path keeps the name found in the list everything works fine inside the loop..but it does not populate the lst_output listbox.I have tried using files, but in vain. It just get the values from the list but does not display that on the listbox.If that can help, then listbox is found in a panel on the form2, but taking it out of the panel does not affect anything.
Why is it that in parts of the .Net architecture that ARGB colours are expected be as type Integer when ARGB is outside the range of Integer? (ARGB requires 32 bits of precission, but Int has 31 bits of precission).Now of course I could just do a conversion, but what freaking conversion to use??? (I'm not affluent with all the VB global methods and the sort)
I've tried things like:
Code: Dim value As Integer = &H80000014 Dim uvalue As UInteger = CType(value, value)
''overflow others include Convert.ToUInt32 -> value was either to large or to small and a few others all offering up nonsense about overflows, when all I freakin' want is a colour that Microsoft's own engineers have done stupid things like expect Integer values in places where UInteger should be, or vice versa. How about some consistency...
Code: Dim value As UInteger = &H80000014 ''<- not represntable as a Uinteger??? Dim uvalue As UInteger = 2147483668 ''<- same value in decimal, same exact value! and it works this says it's not representable as a UInteger?
I accept both C# and VB.NET suggestion, even though I'm writing an app in VB.NET I have two lists of intergers
List1 {1,2,3,5} List2 {2,4,6,7}
I want to have new List3 {4,6,7} which is composed of elements of List2 that are not in List1. I know I can write a nice For Each loop for this but I want it done in LINQ I've been looking for such methods at Enumerable Methods, but I can't find it.
I want Too Know how Can i Fill THat values in the sql Column my Sql Data type is Integer Can i fill any SIGN Valuse like (122,123)(123+123)(321-123)(485;456)(301>908) in these Values Can i use any one in sql column and the column data type is Integer.
When I view the Tab Order in VB 2008, everthing has a tab order number and it is in decimal form. If I click on each item, it appears that I can set the Tab Index but it is hard to see a correlation between the Tab Index and the Tab Order on the form. Most of the items on the form are not going to be tabbed to by the user.
1. Is there a way to clear the tab order and only tab to the items that the user would use and in the order that they would do it?
2. What number should the tab order start with and do you start over with the numbering on each form?

This code doesn't work because the strings returned in the select case block don't match any of the cases that are coded. I need a better way to do this, I imagine there is a more efficient way.
