[2008] Loop Calculation - Showing The Break-even Year
Feb 25, 2009I am trying to write the following application. A project has initial investment, yearly revenue and yearly expenses. The program should be able to take these data and calculate the break-even year, i.e. when the cumulative profits become 0. Also, it should have a listbox that would list the cumulative profit for 10 years. Refer to the example below. Now I know how to show it in the listbox but I am having trouble showing the break-even year. I know how to calculate it but how do you show it in years.
View 8 RepliesBreak Textbox Lostfocus Event?
Aug 20, 2010the scenario is the following: I have a textbox ,next to it a button. The user types a value in the textbox, he presses tab, I search this value in the database in the LostFocus event, if there is no match, a browse form shows and the user can select the desired value. After closing the browse form, the focus goes to the next textbox control (and exactly this I want to prevent). The user can click the button next to textbox to choose a value (the browser form appears), but in this case, after closing the form, the focus remains on the textbox control, because before clicking the button, the focus was on it.
So, my question: how can I disable the LostFocus event? Ok, I figured it out: I must use the validating event. It works. But in this case, if I close the form, the event fires up. How can I disable this?
Get Ctrl+Break On Laptop Without A Break Key?
Nov 12, 2009-new Dell laptop without a Break key.
-VB6 and VS2008 IDEs use Ctrl+Break to pause execution for debugging.
-I need a way to map another key combination to trigger a Ctrl+Break
My setup may make this easier or harder but to be clear I am running Kubuntu 9.10 (latest stable) and WinXP in a VirtualBox VM. Obviously all VB6/VS2008 dev is taking place in the virtual machine.So maybe it's possible to have the linux host send through Ctrl+Break based on a key mapping, or maybe it's possible to remap directly in WinXP. I'd settle for any solution as atm I need to use the XP On-Screen keyboard to send a Ctrl+Break.

VS 2008 - Control A Loop Event With A Scrollbar?
Jun 4, 2010I am trying to use a scrollbar to move forward and back through records in a datatable and to populat an entry in a field to indicate that individual records are selected.In short i want to represent a the sum of a specific field of those records selected. Of course being a scrollbar it has to work in reverse and unselect records when the user moves it backward.
The purpsoe of the scrollbars is that there will be five of them and they will represent years. The records on the other hand represent projects which have an output (say money saving). The idea being projects selected in year one then cant be selected in year two. I am planning to do this by assigning a value that indicates they are already allocated to the previous or other years scroll bar. I can set up a loop to go through the whole data set and do this for a year (and have), but i want to use scrollbars and make it interactive.
VS 2008 - Infinite Loop - Event Triggered Keeps Firing Off The Code
May 9, 2010I'm not even sure what I need to know. None the less lets say I got a timer with an if event to check if said event is triggered then it fires off some code. The problem is if said event is triggered it keeps firing off the code and I only need to do it one time. Whilst letting the timer keep checking if event happened. I hope I worded that right and here is a rough translation in code. [Code] Is there a way to keep checking if an event happened and only fire off the code one time?
View 1 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.

Control Array - Add New Event - Click Event Code And Calling It A Doubleclick Event

The background color does not change to green. Why?

.net - Results Different When Break Into The Code?
Nov 21, 2011I created a small vb.net console app in visual studio 2008 trying to learn .net but my results show differently when I break in the code and press F11 to step through. If I do it this way, the results I expect to get show but if I don't break into the code the results aren't what I'm expecting.
Basically everytime I click a button i want to write four numbers that are random. If I break into the code, these show random numbers i.e. 1 3 4 3 but if i don't break into the code. my numbers are all the same i.e.1 1 1 1. Here is my code, like I said I'm still learning so the logic is probably not correct.
