I have a sub which requires multiple counter variables. Is there a more efficient way of doing this. My example is simple. Image if I had 20 separate counters I was trying to manage. I would have to create 20 separate variables and then increment each in the desired place in the code.
Dim Counter1 as Double
Dim Counter2 as Double
Dim Counter3 as Double
We have a project that needs to gather survey data. On one particular page of the website, there are 21 questions each with a scale of 1-5 where the user selects one radio button for each question in the table. The survey is being coded in VB.NET. The data submits to an SQL database. All the radio buttons are similarly named, so only the number changes for the question [Code]
i wanted to know how to create a for...loop...and specify the counter for the loop to control the animation time. I want the for..loop to increase the speed of the moving object (button) and move it 5 times...
the code i started with is
Private Sub ForNextButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles xForNextButton.Click For Counter = 0 To 1000 'do somtething----the something i want to do is repeat the moving process 4 times and at a fast speed---how do i write that Next
I'm trying to load a file where this file has, like, 10 lines. And I want to load each line (0 to 9) to each TextBox in my app (TextBox1 until TextBox10). So, there's a way to do this with a counter?
Like this mine code (that doesn't works): If (System.IO.File.Exists("configs.ini")) Then Dim configs As String() = System.IO.File.ReadAllText("configs.ini").Split(vbNewLine) Const Max As Integer = 9 Dim TextBoxes(Max) As TextBox For i = 0 To Max TextBoxes(i + 1).Text = configs(i) Next End If
I have a for loop which goes like this - for i = 0 as integer to 100 result &= "Name" & sqldr("name") result &= "Lastname" & sqldr("lastname") result &= "dob" & sqldr("dob") next
The sqldr is the sql datareader (not important here) I want my end result to be Name1 = Sam Lastname1 = Davis dob1 = 01/01/1966 Name2 = ... Name3 = And so on depending on how manyrecords are in database. How do I make this happen in this for loop?
The program is to take an entered string then search for a subset of letters entered through and input box.In my subprocedure Sub btnSearch_Click I am using a loop to move through the entire length of an entered string to search for a set of letters entered through an input box. I can find the set of letters to search for but instead of increasing my counter "Found" for every instance of a match it returns the length of the string instead. I just don't know why the IF doesn't prevent the counter from increasing for every element in the string. I want the counter to increase only when the match is found. I just put 2 message boxes in there to make sure it found the right letter and then display the counter.
Here's the entire

I want to write an Excel macro to set print formats in all worksheets in a workbook. I don't think you can do this by grouping; it appears you have to do it in each individual worksheet. I want to be able to run a macro in any workbook to loop through all worksheets in the workbook and then select the first worksheet.
How do you have the macro determine how many worksheets there are and set the loop counter equal to that number?
Im writing a program and its pulling data from a .MDB to put in a .DAT file.
Here is my while loop:
vb database_connection() sql = "SELECT * FROM tlalist"
[Code].....
In my database there are currently 6 rows. and only 1 row has the TLA_DAY column equal to 1, but for some reason when I look at the .DAT file it creates it outputs the result twice rather than only once.
Once JTLA_count increments it becomes "2", but the while loop still outputs as if its still equal to "1". Ive used breakpoints and the counter is incrementing fine.
I have code, shown below, that works all except for 1 thing: The variables being passed byRef get passed, but once modified in the else section of the "if me.invokerequired" code of RecordData, the variables are never updated in the calling function. To reiterate, the calling function does not receive the updated data that is in the variables custid and amt.When debugging, I see the data change in the else section of "if me.invokerequired", but once it returns from the callback the data is missing.[code]
I'm trying to use variables created within a loop, but I'm not sure how to do this. I've searched around on the net and there is a few recommendations to try and put what I require into a function then just call the function.
Sub Application_Start(ByVal sender As Object, ByVal e As EventArgs) Dim chatters As List(Of Chatter) = New List(Of Chatter) chatters.Add(New Chatter(New Guid("CD863C27-2CEE-45fd-A2E0-A69E62B816B9"), "Me")) chatters.Add(New Chatter(Guid.NewGuid, "Juan")) chatters.Add(New Chatter(Guid.NewGuid, "Joe")) Application.Add("Chatters", chatters)

I am unable to understand last 3 lines that are bold and underlined. Please what is hppening here. Chatter and Chat are two classes defined in App_Code folder. Is there any sight that contains all possible ways to declare and initilaze variables and data structure:
Dim chatters As List(Of Chatter) = New List(Of Chatter)
what if you created a pool of numbers: 1 - 21 and then chose a random selection from the pool? Something like the following:[code]This gets rid of those messy if statements and all of those loops.
I am writing a program and i need to declare matrices but there will be a different number to declare everytime the program is run so I was wondering if anyone knew how to declare them inside a for loop
eg.
For i = 1 to NumberOfMatrices Dim matrix i (5,5) As Double Next
This program asks the user for a number and then an amount to multiply it with and that amount should be added to the initial number. I need to loop because I am trying to display what the amount would be each day for a certain amount of days but in this loop its only calculating for the total .how to get the variables to change value to the updated day. I understand that its just keeping the same value in the variables I just need a push on how to get it to update the values through each loop.
I have this code sample from a book I'm reading which looks to be incorrect:
Imports System.Diagnostics Sub Main Dim pc As New PerformanceCounter("PerfApp", "Clicks", False) 'excepiton here pc.Increment() counterLabel.Content = pc.NextValue().ToString() End Sub
There excepion message I get is: The requested Performance Counter is not a custom counter, it has to be initialized as ReadOnly. I looked for a property to see if I can set it but couldn't find one.
I have some variables that are distinct by numbers, like in1, in2...If I have for loop, how would I access those variables, using the counter, and attaching it to the variable?I believe in JAVA, you could just use in+ct... where ct is the counter to access the variable.also how could you make a new variable in the for loop?Initially I had variables declare outside of the for loop. The problem was how to access those variables using the for loop.
var_nm1 = in1.Text var_nm2 = in2.Text var_nm3 = in3.Text Dim nmList(2) As Integer

This is object oriented programming, and I made the textboxes in1, in2, and in3 using the GUI editor. that was so easy.
In my loop I am trying to remove items from a list that have a certain name. I can't do this with a for-each, so I tried a regular for-loop. It seems the for loop is not working as expected. It always goes over the limit. I had to put an if-then to break out of the loop (very ugly solution). I'm trying to find the correct way to accomplish this. [code]...
This is my first attempt at doing something in VB.net. I would like to be able to read a text file consisting of a column of data values and then pass the data as a variable to a sub that produces a line graph and updates it with each iteration through the loop. So far I have the code to read the file as well as some code that produces a line graph using hard coded values.
I am unsure how to call this sub from my loop such that I can pass that data value read from the file to the graphing sub.
How can I call the "PictureBox1_Paint" sub from my loop? How can I pass variables read from the data file to "PictureBox1_Paint" when I am calling it? Is there anything different that needs to be done if I want the graph to update with each iteration through the loop (for each data point)?

Here is what im trying to do. I have a loop and trying to concatenate it to produce the string. For whatever reason im getting test1, test2, etc instead of the variable equals to. What i am trying to do is get the value test1, etc.... from the concatenating test & cstr(a)
dim test1, test2, test3, test4, test 5 as string test1 = "The" test2 = "dog"
Is there a way to give a value to multiple variables (integers in this case), instead of all at once?
For instance, I have Dim aceVal, twoVal, threeVal, fourVal, fiveVal, sixVal, sevenVal, eightVal, nineVal, tenVal As Integer and, pending listbox selection, I'd like to assign threeVal fourVal and sixVal all values of -1.
i would like to say i am a novice programmer, in year 12. I am designing a small game for my HSC and one of my forms is getting very cluttered with controls and code. To resolve this cluttering, i have had the idea to create new forms for some aspects of the game (such as different game modes and so on). However, in order for that to happen i have to drag some variables of the new form to the old form, (these variables would be just booleans or integers to say whether you lost a game or won a game or something that would carry on to the main form.)
I'm trying to set multiple variables using a textbox.The way I'm trying to do it is have each variable seperated by a space so like this:#If textbox1.text.contains("test") then set variables from textbox1.text for each " " in textbox1.text define new variable(value, string1, string2, int1, int2, int3, int4, int5)#End If I just don't know how I would code something that can set these variables from a single line of text in a textbox seperated by nothing other than just spaces.
I am trying to have it so that when a user hits a button to enter a shop, it will open a popup window which will have the shop's goods. The only problem is I can't figure out how to keep the variables working between the two windows.
I need to get the variable 'gold' to transfer to and from form2(the shop window) and whatever is bought at the store to transfer back to the main window.
Right now, when I go to form2 all the values are 0, and all the variables I used on form1 are undeclared on form2.
How do I access variables from form1 to show up in form2? Is there an easier way to accomplish this than using a separate form?
What is the cleanest way to assign a value to multiple variables? For example, how can I assign FALSE to each of Label1.Visible, Label2.Visible, Label3.Visible, Label4.Visible, and Label5.Visible.Is there anything like
