User Input Of Time In Format Hh /mm / Possible With Datetime Picker?
Oct 13, 2009I would like to capture a start and end time in format hh:mm.Instantly I thought a datetimepicker would be the most suitable component (see code below)[code]Now I'm unable to find a datetimepicker solution to allow settings of intervals like in the numericupdown control and unable to even set a mindate/maxdate in time format. Does anyone have a solution for these requests? I then thought about using a numericupdown control to capture hh:mm time but I could not find a way of doing this in ONE control rather than two whichwould involve code to ensure only valid hours/min values could be selected i.e. 0 - 23 and 00-59 and other date to string conversion/validation.For such a commonly recorded element I'm surprised to find little in the way of solutions other than third party controls.Does anyone have ideas for a way forward for a control to capture time as hh:mm with interval controls for hours and minutes?
View 4 Replies[2008] Checking Time Format From Textbox Input?
Mar 8, 2009I have been trying to check if a user has input a specific time format into a textbox.For example
1- User enters time in hhmm format
2- Checks the input
3- If wrong, MessageBox.Show("Need hh:mm time format")
I have only used IF statement with IsNumeric to check for number input but was unsuccessful with various attempts I can think of for checking a time format as I need Option Strict On and have the following error: Option Strict On disallows implicit conversions from 'String' to 'Date'.Is there a way to like check if the hh:mm has the ":" separator too?

May 12, 2009I'm currently in VB class at my highschool and we just got chapter 6.1 to read on this online textbook that we follow. Anyway, we are doing loops now and the problem reads "Write a program to request positive numbers one at a time from the user in an input dialog box. The user should be instructed to enter -1 after all the positive numbers have been supplied. At that time, the program should display the sum of the numbers." So far I know this much

Now I know this isn't right But I can't find out how I'd pull out the numbers the user entered to get the sum of them and not include -1 because as it stands, when I hit ENTER with -1 the label just shows -1.

Allows A User To Select A Program To Run At A Certain Time For A Specific Amount Of Time All Choosen By The User
Jul 1, 2010I 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.

C# - Convert A Date And Time To UTC Time Based On The Time Zone Of The User?
Sep 6, 2009I 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?

I cannot figure out how to incorporate the number of days into the input box then get it to loop and count the number of times the User inputs in the number of days. Then I have to incorporate it into the equation to get the total distance D = MPH * Hours. What I have right now wil not count up the number of days and locks up after I input one number and will not add anything to the listbox. Because I also have to make sure that they cant add nonnumaric values and the number of hours per day cannot exceed 20. I have put things in and taken them out but it has been 2 days and I am lost now

Sep 17, 2009I'm having an issue with a page I created that was working fine two months ago. Nothing has changed in structure of the SQL tables and I have even done an insert within SQL to the table and all works fine with SQL. So the problem lies within the code. I'm getting this error:
Input string was not in a correct format.

Input String Was Not In A Correct Format?
Oct 26, 2009I am having some trouble with a DataBound TextBox with the Decimal DataType.
Here is the situation:
- I have a TextBox bound to a column in DataTable in a strongly typed DataSet.
- I have an ErrorProvider that has the BindingSource set to the same binding source as the TextBox.
- The Datatype of the column bound to the textbox is Decimal.
- I have my business rules set up as Partial Classes in the Dataset.
- I am capturing the ColumnChanged event in the Partial Class for the DataTable in question.
The issues are:
- The ColumnChanged event fires in all cases except when there is a data constraint. For example you enter non-numeric values in the TextBox.
- Once you violate a data constraint you cannot leave the TextBox empty even though the column is nullable.
In the above scenario the error icon appears beside the TextBox with the error "input string was not in a correct format."
There seems to be an internal event triggering before my business rule logic is able to process.Desired functionalty:Bypass this internal event and present my own error message to the user using the business logic coded in the partial class.
Input String Was Not In Correct Format
Apr 12, 2012I have a dropdown list which extracts data from my SQL database and gives the users two options to choose from (Weekly / Monthly). The database has an ID for each of these. Weekly is set to 1 and Monthly is set to 2. This drop down is linked to a gridview which extracts / displays the data based on the selected item. All of this works perfectly fine. This issue I have is that I want to add some code in my Page_ load event to populate a text box with the selected item. I would also like to set the dropdownlist as default to weekly when a users access thie page. I thought that the two following bits of code would work but I get the message 'Input string was not in a correct format'.
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
'This works fine
lblTodaysDate.Text = GetDate()
'I thought I could complete an If Statement to get the text box to work.

Else

End If
