Nested Loop For DataGridView Not Working?
Dec 3, 2010Dim 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.
VS 2008 Cleaning Up A Nested For Each-loop?
Dec 3, 2009I'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

"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.

Create A Nested Loop With A Variable Amount Of Nests?
Aug 28, 2009OK, 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 cMax As Integer = InputBox("Max")

VS 2008 Nested Loop Duplicating ListView Items?
Jul 29, 2010I'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.

VS 2010 Nested MDI Parent/Child Forms?
Mar 3, 2012I have a MDI project that has a parent and several children forms. In some of the children forms I would like to make one of the forms to be a parent form with children. On this child form I wanted to make a tabbed MDI, which I can do, but I have found out that I can't make a child form a parent, from what I have found.
Is there any way to get around this? (As in nested MDI forms.)
VS 2010 Variable Scope In Nested Classes?

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.

Evaluates Loop Condition In Do...Loop Statment To Determine Whether Loop Instructions Should Be Processed
Mar 14, 2011Makes the following statement about the code below:
**"The computer evaluates the loop condition in the Do...Loop statment to determine whether the loop instructions should be processed. In this case, the inputsales <> String.Empty condition compares the contenst of the input sales variable to the String.Empty value. As you know the String.Empty value represents a zero length, or empty, string if the inputsales variable is empty, the loop condition evaluates to True and the computer process the loop instructions. *If on the other hand the inputsales variable is not empty, the loop condition evaluates to false and the computer skips over the loop instructions.
Based on the code I think it is the opposite: ...that while the inputsales value is not empty it should evaluate to true and process the loop and if it is empty it should evaluate to false and skip the loop?
See below.

Aug 28, 2010I'm using a picture box to show an animated gif on my form. When i created the gif, I set it so it only loops once. The gif plays correctly in a browser, but when i set the image of the picture box to my animated gif it continuously loops.
I only want to loop once through the images embedded in my animated gif when i set the image of the picture box. What is the easiest way to do this? Does anyone have or know of any sample code to do this? I have been searching this for a while, but have not been able to find anything.

VS 2010 Stopping A For Loop?
Feb 10, 2011I was wondering how someone could stop a For loop in the middle of it, according to parameters. I have tried but cannot find a solution that works, I suppose an example of this would be if a loop were increasing a label by 1 from 0 to 100 and the user sets it to end at 57 or any number in between and when the loop reached the number to stop.
