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.
so far i got
code
For Each item As Reflection.FieldInfo In GetType(NameSpace.ClassWithNestedClasses).GetFields
rtfAppend(item.Name & ":" & Tab & item.GetValue(Me))
Next

View 8 RepliesI'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

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.

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.

So I have some vb.net code, and I have a nested For loop inside a For loop, and then I have EXIT FOR statement, will it break out of one loop, or the whole chain?

The messagebox appears, but the method is still executed. Which means it isn't stopping when it finds the match. I tried exiting the loop, but it still doesn't work.
Basically, what I'm doing is navigating to a website with a backgroundworker.In the WebBrowser1_DocumentCompleted event, I put code to fill in a form and I set the value of a boolean called "formFinished" to true once the form has been finished and submitted. The problem I'm having is that it only posts data to the second website, no matter the order of the websites. I'm wondering how this is possible since I have a boolean in state which only gets set to true once the first form has been submitted. So I have no clue as to why it only submits the second one, but not the first one.

I'm essentially try ing to loop through every row in a datagridview, and trying to remove the entire row, if a certain cell's value matches another value. Please find the code below.

when using a loop for a datagridview i have something like the norm.
do until datagridview1(0,i).value = ""
stuff here
loop
the issue is if a value might never be "" and datagridview1 isn't always the same size ill get an error because it will index past the number of rows there are
so how can i tell it to loop until it gets to the end of that column or row ect.
