SQL Query - Execute A Sql Query That Will Display The Top 5 Based On Average?
May 17, 2012I have a data table that looks like this:
USERNAME ICOUNT IAVERAGE DATE_LOGGED
LAGX01 1245 1245 05-07-2012
LAGX02 2211 1422 05-07-2012
LAGX03 1698 1112 05-07-2012
LAGX04 4598 1555 05-07-2012
LAGX05 2589 3245 05-07-2012
LAGX06 3321 1155 05-07-2012
LAGX07 3698 3458 05-07-2012
LAGX08 2589 4587 05-07-2012
LAGX09 1598 1142 05-07-2012

LAGX11 5547 2011 05-07-2012
LAGX12 9456 3459 05-07-2012
Now, I want to execute a sql query that will display the top 5 based on average, so i did this:
SELECT DISTINCT USERNAME,IAVERAGE FROM myTable WHERE IAVERAGE > 0 AND DATE_LOGGED='05-07-2012' ORDER BY IAVERAGE LIMIT 0,5 and the result is:
USERNAME ICOUNT IAVERAGE DATE_LOGGED
LAGX03 1698 1112 05-07-2012
LAGX09 1598 1142 05-07-2012
LAGX06 3321 1155 05-07-2012
LAGX01 1245 1245 05-07-2012
LAGX02 2211 1422 05-07-2012
Now, I want to numberize my query result, so it will look like this:
RANK USERNAME ICOUNT IAVERAGE DATE_LOGGED
1 LAGX03 1698 1112 05-07-2012
2 LAGX09 1598 1142 05-07-2012
3 LAGX06 3321 1155 05-07-2012
4 LAGX01 1245 1245 05-07-2012
5 LAGX02 2211 1422 05-07-2012
Name Folder Based On Value In Label?
Mar 15, 2012I have an application you log into based on an ID number (example 45)
In the app, there is a label. By default is has "lblID" in it, when when you log in, the 45 goes there (comes from MySQL)
I need to create a new folder on startup, and that folder needs to be named according to that ID number.
The problem I'm running into , is when the application starts, it creates the folder just fine, but it never names it according to the ID. It always names it lblID.
The code to create the folder is in the frmLoad-
x.CreateIDfolder()
Then it goes to the code in a module-
Public Sub CreateIDfolder()

Dec 11, 2009Just wondering if someone can at least point out where I'm going wrong here. I've already got the code to populate the listbox by a button click from the user and am just trying to figure out how exactly to alter the text of a label based on what the user selects in the listbox. From what I have the Label will display the case else selection but nothing else despite my best efforts to get it to change. Here is what I've tried. I realize it is very trivial, but I am only a beginner to programming.

Change The Text Of A Label In My Form Based On A Timer?
Aug 10, 2011In a piece of code I am writing I am trying to change the text of a label in my form based on a timer. I have MANY other labels that are all updating in their own subs and when I try to add any new labels(in any sub) to update it wont. I am using Label.Text = counter where counter is a string that is changing. I have tried refreshing the form, Label.refresh() Label1.Update()....The only thing I think it could be is that the redraw is being held up by other calculations on the cpu. How can I make the label text change and update properly?

Alter The .visible Property Of A Label Based On If A Variable Is Positive Or Negative?
Apr 11, 2010I want to alter the .visible property of a label based on if a variable is positive or negative (Hiding it for negative values)
But I want to do this for lots of labels so If Statements are too bulky.
I tried this:
Label1.visible = CBool(IntVariable1)
But it turns out CBool returns True for ANY value and False for Zero.I'd assumed it would be True for positive values and False for negatives.How can I do it without if statements?I considered Modulo or SquareRoots to somehow convert a negative number into zero, but didn't want to complicate things with imaginary numbers.
