Getting Loop Through Adding Each Result Without A MessageBox Stop In Each Loop?

May 3, 2010

I have written a function that gets the alexa ranking of a given url, now this function works perfectly but I want to loop through a ListView of urls and grab the alexa rank of each item (url) with my function.The code works great if I put a MessageBox in the loop to test that the function is returning a value but when I remove the MessageBox the loop does not work.I need it to loop through adding each result without a MessageBox stop in each loop.

vb
For Each Item In ListView1.Items
Dim result As Integer
result = GetAlexaRank(Item.Text)

Evaluates Loop Condition In Do...Loop Statment To Determine Whether Loop Instructions Should Be Processed

Mar 14, 2011

Makes 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.

Option Explicit On
Option Strict On

Imports System.Globalization

VS 2010 : Use A Stop Button To Stop A Loop?

Dec 7, 2009

I created a form and have the variable inputs for 4 motor run statements. Then with a start button the script starts and it is surrounded by a for next statement to loop 10 times. It works fine but if i need to stop the execution of the script with a stop button. I put the stop in a new section but of course does not work to do a motor stop. It just causes the exe to not respond till the loop is complete. Just need to be able to stop the Run1_Click button section.

Edit:I do not mind if it finishes the 4 motor run commands and then stops execution of the loop. So need to figure out a way to trigger a stop from a button on the form to stop the cycle. For the future the loop will be a variable integer input so 10 will not be the standard.

Edit::Does a ' Do ' statement sound like the thing to use? If so how and where would I place that? Have a Stop button on the form and it would stop after the 4th motor run command.

#End Region
Declare Function InitStp Lib "stp.dll" () As Integer
Declare Function RunMotor1 Lib "stp.dll" (ByVal steps As Integer, ByVal interval As Integer, ByVal direction As Integer, ByVal outputs As Integer) As Boolean

Run A Do While Loop - How To Stop On Keypress

Aug 2, 2011

I need to run a do while loop or some way of starting a search directory loop, then if a user presses another key, it will stop that current search, and restart with the next letter entered. I appreciate any help given and insight. I am basically trying an incremental search feature, but currently whenever a user types in one letter, it does a full search, then on next letter it searches again. I want it to stop if they are still typing in letters.

If SearchTextBox.Text <> "" Then
Do Until Form1.OnKeyPress 'NEED HELP HERE

Using ESC To Stop A Process While Inside A Loop

May 18, 2010

I would like to be able to stop a loop while executing using the ESC key.I've found a lot about using the above key from within a Form (for example, to unload it), but very little for the use of the key within a Procedure (Sub, Function) and particularly with respect of preventing a loop from carrying on execution.

WHILE LOOP Displaying Wrong Result When Counter Is Incremented?

Feb 23, 2011

Im writing a program and its pulling data from a .MDB to put in a .DAT file.

Here is my while loop:

vb
database_connection()
sql = "SELECT * FROM tlalist"

[Code].....

In my database there are currently 6 rows. and only 1 row has the TLA_DAY column equal to 1, but for some reason when I look at the .DAT file it creates it outputs the result twice rather than only once.

Once JTLA_count increments it becomes "2", but the while loop still outputs as if its still equal to "1". Ive used breakpoints and the counter is incrementing fine.

Forms :: Stop Loop With Button Control?

Dec 5, 2010

I am fairly new to VB but really enjoying programming. I'm looking to create a counter that counts to 25 and loops back around again with a button control and another button control to stop it. So I press a button to start and another to stop and I want it to display the number it stopped on. Is this possible? and how do I do it if it is? I can figure out how to display the label and create a simple counter(that doesn't loop), but I'm unsure on the rest.
