Counter Intuitive But Not A Show Stopper?
Oct 25, 2010
Interesting that the HScrollBar control works from Minimum at left and Maximum at right but the VScrollBar control has minimum at the top and maximum at the bottom. This is counter intuitive but not a show stopper since you can tweak your code to correct it.However: another issue is that the Large Change value will not allow you go go to the Maximum value unless it is evenly divisible into the Maximum value. You can always set the Large Change value to 1 and it will work OK but what good is this?

Suppose I want to show a counter in a textbox w/a slight delay (for loop) after the form is loaded. I tried code below and it just shows the last #10.
Public Class Form1
Private Sub Form1_Shown(sender As System.Object, e As System.EventArgs) Handles MyBase.Shown
[Code]......
I realize I could use a timer or sleep function but I'm trying to understand why this doesn't and/or shouldn't work.

I have this code sample from a book I'm reading which looks to be incorrect:
Imports System.Diagnostics
Sub Main
Dim pc As New PerformanceCounter("PerfApp", "Clicks", False) 'excepiton here
pc.Increment()
counterLabel.Content = pc.NextValue().ToString()
End Sub
There excepion message I get is: The requested Performance Counter is not a custom counter, it has to be initialized as ReadOnly. I looked for a property to see if I can set it but couldn't find one.

SQL statements:
SQL = "SHOW TABLES;"
Try
conn.Open()
The remarked area works fine when I'm accessing a specific table. I've successfully inserted the products_model field into the combobox too. The datagridview does show the table names in the db using the SHOW TABLES sql statment, but I'm not understanding how to get this info into the combobox instead.

In the following block of code always returns zero for the CPU usage. However, if I run it through Visual Studio in debugging mode, do a "Quick watch" on the variable "pcCPUCounter", add ".NextValue()" at the top, and tell it to reevaluate, that returns the varying percentage (eg, 5%, 71%, 16%, etc etc) as the processor utilization fluctuates.
Why would the code always print out zero, but the quick watch doesn't?
Private Sub UpdateCPUUsage(ByVal strSelectedServer As String)
'Performance items come Performance Monitor: perfmon.msc.
'The right-click on columns at bottom and select "add counter" to see list.

How to make my counter work. I keep feeling like I'm putting it, or maybe just part of it, in the wrong place so I've been moving it all over the place but haven't found anything that works yet. I'll paste my code below and it will be the code that seems to not stop when it reaches the end of my counter. Other ways I've tried it make it stop after one or two, depending on what I did to the code at them time.
Here's what I have at the moment:
Public Class mainForm
Dim guessCounter As Integer
Dim correctAccumulator As Integer
Dim totalAccumulator As Integer
Dim answer As Integer
[Code] ......

I am trying to create a list box that can have things added and removed from it with the use of add and delete buttons in subroutines, i have also got a limit of 20 as the maximum number of items in the list box, also i would like the list box to be able to update the number of items in it after the user adds or deletes items from it: here is my code:
Public Class Form1
Private Sub cmdAddZp_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdAddZp.Click
[Code]....
the first part is for limiting the number the user can add to the list box, the second part is the delete function and the last part is trying to count the number of items in the list.

Okay my assignment is to change a code up using two functions instead of a subprocedure to calculate total rainfall and avedrage rainfall and then to add a startover button to the application which not only clears all the labels but also clears the counter and accumulator. This is what I have gotten so far my functions do not work and I can get the labels cleared. I just can't get the counter and accumulator to reset back to zero
