VS 02/03 Loop Through Object?
Jan 5, 2011In an application I am working on I have created a product class which represents an inventory item. I have also created an inventory class which represents a collection of product objects.In the constructor of the Inventory class I load 4 products into a product collection. Each product consists of a code, description price and quantity. Within the form load i would like to add a procedure that loads each products code property into a combo box.Obviously I could do this by hard coding the values but I would like to loop through the collection of products and populate the combo box with the codes contained inside the product collection. This is what I am struggling with. Below is the code for my inventory and product class.
Public Class Product
Private sCode As String
Private sDescription As String

Detect A PictureBox Click Within A While Loop?
May 8, 2009I know this may seen a simple request, but if you start a timer, and jump into a while loop, how come the timer stops working unless you use DoEvents?

View 1 RepliesLoop To Be Ended By Button Click?
Feb 17, 2009I am writing a simulator program that gets its I/O from external sources with results displayed on a form. I heve composed a form, with graphics that look great, but when I call a loop to actually start the simulation, all my labels on the form go transparent and the 'stop' button I have created does not function.I have tried placing this continuous loop in the form code box and in a separate module but to no avail. Even just putting a clock on the form does not work - it prints to screen initially, but only refreshes when I run the cursor over the stop button.This leads me to believe (remember I am a VB novice)that a form is full of Subs that only run once on form load.So where is the main body of code placed that will run continuously; from where I can check the button status and update the form?

View 19 RepliesVS 2010 An Extra Click To Get Out Of A While Loop Using .DoEvents() ?
Mar 15, 2012I wrote a small API gui to communicate over foundation fieldbus.I've used a While loop that constantly reads some parameter values from the bus. At the end of the While loop, I put Application.DoEvents()so that I can use another button to stop the reading process. It all seems good and easy.. but there's one problem: when I get the While loop running and wish to stop the process, I have to first click somewhere on the form, anywhere, before I could click any buttons(either 'stop reading' or 'reset' button mostly). That extra click makes my form seem unresponsive and lame.I wonder whether this is a problem pertaining to DoEvents() or my use of Foundation fieldbus.
View 1 RepliesLoop Through A Collection Object In VB 2010
Aug 30, 2010I'm trying to loop through a collection object in vb2010.The code was originally used in Vb6 The book said that I needed to code a NewEnumerator method first in order to be able to loop through my collection. I coded the following:

It gives an error for IUnknown, staging that IUnknown is not accessible in this context because it is a 'Friend'.In the line in the function I removed the Set since it's no longer needed.The error message for this line is '_NewEnum' is not a member of 'Microsoft.VisualBasic.Collection'What are these messages and how do I fix this in VB 2010?m_colCourse is not a system collection.

View 2 RepliesEmulate Mouse Double Left Click In A Loop?
Nov 20, 2011I am trying to make a program that AUTO left clicks the mouse according to a set second interval (This will be repeated in a loop) What I got so far is test event going on because of course you have to brake the loop somehow and stop the emulation of the left mouse click.
I have on my form a Text box and I dont know how to go about this. I want the Keyboard buttons A & S to be used to start and Stop the Loop and the Textbox to take in the input form the user in seconds.. and loop it until the user pusses S to stop..
1).. Use the Textbox on the form to let the user input the time interval between clicks...
2).. Use The Keyboard's (A) Key to START the program's Double Left Click Loop.
3).. Use The Keyboard's (S) Key to END the program's Double Left Click Loop.
4).. The Program MUST INFINITY Loop Mouse DOUBLE Left Click (UNTIL USER Presses (S) Key) (A=Start, S=Stop)
5).. The Emulation of the Clicking itself has to work in all Windows Maximized or Windowed Full-screen even on the desktop or within other programs like games. (EXAMPLE: Can run when a game is running at Full screen or windowed.
I'm sorta confused on how to do this seeing that I never dealt with emulation or events with the mouse itself. However I do know that there has to be certain key press events and a true or false statements placed in code.

Implementation - Loop To Update Properties Of Each Object Of A Set Of Custom Objects
Jan 4, 2010I am using a loop to update properties of each object of a set of custom objects. The routine knows which controls to update because the controls value is not empty, I don't want the routine setting the corresponding properties to nothing when the control is empty. Now I know how to do this perfectly fine with IF statements such as:
CODE:
But this feels really redundant doing that same IF block over and over for each property/control combination, I thought about creating a separate routine that takes the control as an argument and does all the repetitive IF blocks but I don't know how I could also pass an object property to tell the routine to update that particular property.

View 7 RepliesEvaluates Loop Condition In Do...Loop Statment To Determine Whether Loop Instructions Should Be Processed
Mar 14, 2011Makes 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.
