Create A Nested Loop With A Variable Amount Of Nests?
Aug 28, 2009
OK, after trying to get this working for a couple of days now I decided that I would turn to the experts here. I am trying to create a nested loop with a variable amount of nests. Let me elaborate. I have a program that first asks for the minimum and maximum amount of loops, I currently have a SELECT CASE statement that addresses each level of nesting individually.
Dim cMin As Integer = InputBox("Min")
Dim cMax As Integer = InputBox("Max")
Dim c1, c2, c3 As Integer
code For Each item As Reflection.FieldInfo In GetType(NameSpace.ClassWithNestedClasses).GetFields rtfAppend(item.Name & ":" & Tab & item.GetValue(Me)) Next For Each item As Reflection.PropertyInfo In GetType(NameSpace.ClassWithNestedClasses).GetProperties()
[code]...
which gets me the simple string vars and properties of my top class, but how can i apply this to loop through all sub classes and get there vars and props?
I intended to do another SQL query inside here and retrieve data from another table by using the "category_id".I know the problems that asp.net required me to close the data reader before proceed to another query. But is there any solution for me to do another query and open another data reader within the opening data reader? [code]
Dim cv As Integer Dim cc As Integer Dim CurrentValue As Double Dim ObsoleteValue As Double
[code]....
Basically this code works for the first column of the DataGridView. It sort of stops iterating after the last calculation of the row is performed and doesn't change the cc value at all. Meaning the loop gets stuck after the first iteration.
I'm comparing a temporary table to an another table, to check for changes in the cells. The way I'm doing it, is that I'm using three loops; one to loop trough the temporary, one to loop trough the other table and a last one to loop trough each column. Here's the
vb.net For Each row As DataRowView In View For Each drow As DataRowView In view2
[Code]....
"emitid" is the column I use as a reference to be sure that I'm comparing the correct rows, and the column order will always be the same in both tables.
I'm gathering a list of files within a directory and then adding them to a ListView:
VB.NET
For Each f In Directory.GetFiles() Dim lvi As New ListViewItem lvi.Text = f.Name
[code]....
The exclusion list works great, but it duplicates each item in the ListView several times. How many depends on how many items that it excludes.
I understand why it's happening, but I can't figure out a way around it. I have to loop through the items in the ArrayList so that I can compare them to the other items.
I need to induce a variable amount of lag in vb.net. System should be noticeably slower. I can raise the CPU usage of the program with infinite loops and some variable creation/assignments, but how can I actually cause lag? I'd like to have an "InvokeLag" sub which will perform an action to slow down the computer, the faster the function is called the faster it lags. The function should be as mundane as possible, not modifying anything or doing anything to cause damage other than simple lag.
I have put together the following code to illustrate the problems I've been struggling with:
Public Class OuterClass Private _OuterProp1 As Boolean = False Public Property OuterProp1 As Boolean
[code]....
I need to be able to refer to outer class properties and variables in an inner class, and I need to have a variable in one inner class set in a different class. I've tried Public, Private, Protected, Friend and all kinds of combinations of them, and I can't figure it out.
I have made an app that the user has to type a number, and i want the process for the app to do this how evermany times the user wishes it to do.
for example, the app is ment to create a line in a text document, so they write in textbox1 what they want written on the line, and then in textbox2, tey say how many lines they want to create.
How can you trace the amount of memory used by each variable, process in a program? I tried CLR 2.0 but am not sure how to read the results. Are there any really good articles on CLR 2.0 that describes what I am looking for?
dim a as integer = 5 dim b as integer = 1 dim c as integer = 10
What is the most efficient method of determining which variable has the largest value while using the least amount of code? I know this can be done with if statements, but there must be a more elegant way to do it.
I'm trying to work out a program where you can set up a variable amount of timers (like egg timers). Each timer works independently of the other (you can stop a timer, reset another, and so on, and the rest are not effected).I thought of using a single timer and then creating a custom egg timer class to handle the countdown, store the current time, etc, and use a collection of these classes inside a timer event (at the tick, do a for each to reduce the countdown on the classes by some milliseconds).Then I got to thinking: all of these egg timer classes in the collection with the for each loop may cause some accuracy loss (say, I add 50 egg timers).
Does anyone think the accuracy loss for updating all of the egg timers would be too adverse? Should I try running them on separate threads (have not thought about how yet), or will that make much difference?
i just got 1 question how do u create a (in excel ) variable table (database) inside a function which could be called for filling and reading through "for to next" loop module
Im trying to add a variable that shows amount of tax deducted in a list box among other output variables. If anyone can help I would like to know how to code the lstResults.Items.Add("-$ " & Tax & " Tax") bracket to display the amount of tax deducted from the total salary wages.

I have a mesurement that could be any random value, just for fun well make that 2440mm i need to divde that by the industry standard of 610mm which comes out at 2440 / 610 = 4
Programicaly written NEWVAL = YVAL / STDVAL
NEWVAL (4) gives me refrence to how many instances I want to append a new line in a txt file I know that I want the first line to say 0,0,0 and the second line to say 0,610,0 the third 0,1220,0 the fourth 0,1830,0 and the last 0,2440,0, though this is easily achived with addition how can I automate vb.net to produce a new write line for each each instace of 610 if the YVAL is user defind.Put in simple terms half would be missing if the YVAL variable is double in length at 4880mm?
I am looking to create a function in which I can pass in an integer (count) and create an amount of picturebox's based on the count.For example if I pass in an integer count, it should do this, only I don't know the correct syntax for it.[code]I am making a huge list of pictureboxes that will scroll on a form, 5 showing at a time.Also, if there are a huge amount of pictureboxes, will I be better off keeping like 7 pictureboxes on the form and keep rotating images throughout? Images are coming from a folderlist in a listbox (so I can easily pull the path of the image from an index).
I am creating a roulette wheel using microsoft excel visual basic. I want to create a table with the amount of money you have that goes up or down based on wheter you win/lose. This is what I have so far:
Public Sub spin() Dim speed As Double Dim spin As Double Dim maxspeed As Double
I have 10 textboxes. I want to make a certain number of these textboxes visible. The user enters a number from 1 to 10 to determine how many textboxes are visible.The textboxes are named textbox1, textbox2, .... , textbox10How do I set up a simple for loop to accomplish this?
VISUAL BASIC 2008. Program Description: Create a program that calculates the amount of quarters, dimes, nickels, and pennies are needed from an amount of change (entered in pennies). The program should use the largest coins possible (for example, fifty cents should use two quarters, not five dimes, fifty pennies, etc.)
I don't want the code already written out, I need somebody to walk me through making a code. Also, this is my first class dealing with computer programming so all we've learned so far is declaring variables and how to label objects, the simple stuff. I'm at a loss at how to start because a quarter is worth 25 but the program is supposed to show how many quarters once a user enters the amount in cents.
I'm working on something relatively simple I am trying to create a dynamic amount of comma separated strings.I have a variable (numberOfStrings) which is the number of different strings I need.I just want to loop thru the aryDrivers and assign then to the different strings.Dim aryHeats(numberOfStrings - 1) As ArrayList
Dim aryDrivers() As String aryDrivers = txtBatch.Text.Split(",") For i As Integer = 0 To aryDrivers.Length - 1 For j As Integer = 0 To aryHeats.Length - 1 aryHeats(j).Add(aryDrivers(i) & ",") Next
