View 2 Replieswell i am having a couple of issues with this particular homework problem and this is my first programming class so there is probably quite a few mistakes well the homework problem is to take three double values entered by a user and display the largest and smallest using math.max and math.min and display the smallest and largest so i thought i could use a listbox and take the values that went to the listbox and assign variables to each so i can try to use each variable in the math.max and min but im not making it to far and i actually might be way off

Say I have a code with 3 methods that do some pretty intensive work. Would executing these methods on 3 seperate threads be faster then executing them one after the other on a single core cpu? And what if it's a dual core or HT?
View 8 RepliesI am trying to make a list, separated by a comma, of entries from a single column in a SQL database. I have been spending the last several days searching for a way to do this, but every thing I found either didn't work, or wasn't exactly what I was looking for.
The query will pull all the email address that are not null. What I need to know is how to take the result of that query and make it look like this:
email0@address.com, email1@address.com, email2@address.com, etc, etc, ...
I feel like I should know this, but for the life of me, I can't remember nor can I find it in any of the textbooks I have.

I use SqlParameters when executing database statements. I know that I can replace a single quote with two single quotes... but in the past SqlParameters took care of this for me. I have two projects.. in one, the SqlParameter does this and it handles single quotes fine, in another, it does not and I'm at a loss why (I even copied and pasted the code):

View 9 RepliesI am trying to update a row or a single cell in ms access through vb.net. But when i update the text box named NRIC, say for example i want to update "s4522147B" to "tr4521856C" and mean while leaving the other fields the same.
But the thing is when i make the changes in nric.text (textbox), the dataset actually updates the whole column in the table instead of the selected textbox.
Below is my code for the update part

View 2 RepliesI have very basic question, I'm really not familiar with vb.net.
I have code like this: Dim minutes As Integer = (55 / 60)
I want this to return 0 to me, integer 0 (no decimals), but vb.net rounds this to 1.
Can someone hint me up how to accomplish this ?
edit. OK for those with same problem try dividing with (Yeah, it's not escape character in vb.net)

I have a group of 25 labels named Label1, Label2, Label3, ... Label25 in a square of 5 per row, 5 per column and I wanted to assign the backcolor to all of them on a loop and assign a value of "True" or "False" to a matrix of 25 boolean values representing them.
But I was getting errors on the pattern created.
My approach was to use a substring containing a number copied from the label names:
Num = Val(sender.name.substring(5))
And the subindexes of the matrix:
p = (Num - 1) / 5
q = (Num - 1) Mod 5
The values for the lower corner of the matrix were rouded to 5 instead of being 4. Instead of (4,0) ,(4,1), (4,2), (4,3) (4,4) I was getting (5,0),(5,1)...(5,5)
So I solved the problem by creating two single variables "A" and "B", doing the divission and MOD operations on them, finding the floor of them and then converting to integer:
Private Sub Label1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles _
Label1.Click, Label2.Click, Label3.Click, Label4.Click, Label5.Click, _

View 1 RepliesI need a function that takes a decimal, with a certain number of digits behiond the comma and convert it to a string with a different number of n digits behind the comma. (to display it)My problem is the rounding ip/down.
like 123,789 with n = 2 --> 123,79
or 123,4 with n = 0 --> 123
or 123,5 with n = 0 --> 124
I did not find an existing function that does that, so I wrote one myself.However the code has become soo complex and it still does not work well, and I get frustrated to spend soo much time with something so trivial.Does anyone know a function that can do this? There must be something out there.
What is the rounding method that VB.NET uses when a double is used in a for statement like this. It looks like 5.5 is rounded to 6 and 10.5 is rounded to 10. The output of the program is 6 7 8 9 10
Sub Main()
Dim A As Double

Im working on a program that is about to drive me nuts figuring out how to round and show only 3 or 4 numbers past the decimal placement and also show the scientific notation.
Here is an example of the code.[code...]
