Does anyone know of a good way to have a user enter an amount of time (hours and minutes) using winforms controls? At the moment I have two numeric up downs, one for time and one for minutes that I then parse to create a timespan. The only other idea I have is a text box that a user can enter a "00:00" time in, and validate the input. Both of these ways seem a bit bad (in UI terms) though.
View 5 RepliesI have a question in relation to formatting text fro 24-hour time.
The format I require is always as follows 00:00
How can I make the ":" appear as soon as the second digit is entered as this is required to separate hours from minutes and also how can I force a 0 to appear for any numbers up to and including 9?
Examples being: 00, 01, 02, 03, 04, 05, 06, 07, 08, 09.
These zeros are required but may be forgotten by the user entering them into the textbox?
I am trying to make a program in visual basic 2010 where the user enters hours minutes and seconds into text boxes and then the program will count down from that until its equal to 0 when a msgbox appears and says its finished. I was converting hour entered, minutes entered, and seconds entered all into seconds and then having a timer subtract 1 from that until its equal to 0. But the problem I'm having is that I want to display the hours, minutes and seconds left in a label to the user in a format of: "hours: 0 minutes: 23 seconds :42" but how to display it in this format.

View 9 RepliesIs there a way to determine whether processes have been opened or closed during a given time frame? I'm working on code that will take an initial copy of your processes list, and then based on a timer, continue to take copies, which will compared to the initial processes list to determine which processes have been opened or closed until the timer ends. I'm capturing the processes list's in an Array list.
Dim processesList As String //Initial processes list
Dim processActivity As String //Opened or Closed processes
Dim processesAtStart As New ArrayList // Initial processes as ArrayList (To Compare)
Dim processesCheck As New ArrayList // Latest processes as ArrayList (To Compare)

View 2 RepliesI have a program that allows a user to select a program to run at a certain time for a specific amount of time all choosen by the user. Everything works with the exception of if my program has launched the other program, my program become non-responsive. Meaning I am not able to look at that window again. Not that one really needs too, because when time is up my program closes the program it opened, then closes itself. I just want to be able to see my program when the other program is running. how to do this and perhaps drop me some links, that would be wonderful. This is what I have coded, but like I stated there are no code errors.

View 1 RepliesI have a simple WinForm that is using a Tab Control to simplify data entry. The very last page has a text box that allows the user to "set a name" for the file. I really want to simplify this and suggest how the file should be named. What I want
is for when the tab page is entered (consider that generically) that the text box is pre-populted with a name.
This code will do what I want, but only the first time the tab page is entered. what I am apparently missing or a better way to do this?

I have an ASP.NET application with a SQL Server back end. I am storing all my dates in UTC format and doing the appropriate conversions to the local time zone of the browser viewing it. One of the pages asks for a start date and end date (no times).
I am taking the start date and setting the time to 00:00:00 hours (midnight) and I'm taking the End time and adding a time of 23:59:59, so that the date range covers the whole day. Now what I'm trying to do is do a SQL query to do a search for records in this date range. The problem is, the data in SQL is in UTC time and the user is typing their dates and times in their local date and times. My quickest solution was to convert the date and time to UTC, then search the records. However, by doing this, I am to believe ASP.NET converts the given time and date to UTC based on the server time zone. How can I convert a date and time to UTC time based on the time zone of the user?

View 6 RepliesIm using Visual Studio 2008 Ive created auto click programs through tutorials, Mouse Recorders, also through tutorials. But nothing is helping me with the project at hand. It has now been a month of going through basic VB.net tutorials, and more advanced ones, all with success.. but none telling me what I need for this project.
So here is the project.
When I open this program.. it will have two buttons.. Start.. and Stop. Both set with hotkeys(which I have figured out how to do). When the program starts, it will work, kind of like an auto clicker, but the clicks I need in different, set locations, and with a different time frame in between clicks. The whole program will loop until stopped(with the hotkey).
I Create an application that when a user enters a positive integer value in a input box(the default number is 10) when the OK button is clicked, the application should display a message box with the sum of all the integers form 1 through the value entered by the user. If the user enters a negative value, the application should display an error message. I believe I have to use a loop condition but I have no idea what to do.
EX: User enters 10 in the input box once OK button is pressed a message box pops up and says "The sum of the numbers 1 through 10 is 55". Use the following test data to determine if the application is calculating properly
VALUE SUM
5 15
10 55
20 210
100 5050

Ok so I have designed a program to figure out commissions for phone sales at my company. Since the devices we sell and their associated prices change over time, I had to make that data within my program dynamic. I have a form within my program (frmprice) that has 160 textboxes - 80 for the devices and 80 for the associated prices. Now I hard coded the .text members with default values for our current stock of phones and prices.
I also added code so whenever that form with the phones and prices (frmprice) closes it saves any changes that have been made to either the phones or prices and when the form loads it overwrites the default data with any data that the user had entered at last run.
HERE is my logic problem. At the very first run the program is overwriting the default hard coded values with "" because no user data has ever been entered before. So when the form with the prices loads, it passes the user entered data from last run which is null because it has never run before. If I test to see if default value <> the user entered data before it executes the code to pass the user entered values it will always test to be true because the user entered data is null at first run. If I test to see if the default value is = to the user data it will always at first run test to be false because there is no user data yet.
HOWEVER once the user entered data is initialized (anytime after the first run) I need the program to pass the user data from the previous runs back in. Just NOT at the first run. Here is the code i am using: (in the code below the variables ending in "val" are the ones that are of the type string and are saved in the application settings) The frmprice_Load Event:

I created a usercontrol which has a Textbox and a Label. Setting the (boolean) textvalidity property we can toggle the icons on the label to show if the user has entered a valid input.
Sub New()
' This call is required by the Windows Form Designer.
InitializeComponent()
[Code]......
The problem is... when the control is used... the constructor initializes it to true (According to my code) so the icon is already displayed.
I've got a (hopefully) quick question. I've got textboxes attached to a binding source on one of my forms, and when I add, then clear, the data for the next entry to be added a small problem arises. If the user has previously entered something into, for example, Textbox3 and the user does not have the data for Textbox3 the user cannot move to the next field unless something is entered into the box.

I'm trying to create an app to launch at start up that will ask you what applications you want launching, or if you want all your favorite app's to start up etc. But before I go any further, I think its crucial to know how to save settings that a user has entered (such as program location and name in this case) so that he/she doesn't have to enter them every time at start up.
So far I have just made this, can anyone tell me how I would get it to save the settings entered?
