im trying to get the user of my program to enter their date of birth ad for the program to return how old they are in years, months and days (you are 10 years, 3 months and 23 days old) type thing and if its their birthday, to return an appropriate message.atm ive got a textbox for the days, a combo box for the month and another textbox for the year. i guess the real question is how do i use these to do the above.
View 9 RepliesI am in a VB 2010 class right now, and I'm suppose to write a program that requests the user's date of birth and then display the day of the week (such as Sunday, Monday, ect...) on which day they will have or had their 21st. Birthday.
I already have the GUI made up with a MaskedTextBox set to simple date and it is named = mtbDayOfBirth
I also have the button already to calculate this, and a read only text box named = txtBox2.
My code so far is:
Private Sub Button2_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button2.Click
Dim d As Date = CDate(mtbDateOfBirth.Text)
txtBox2.Text =
End Sub
End Class
The only thing in my book only talks about how to pull the number of days from your bday or pull the full birthday as like the 04/06/1992 would return Monday, April 06, 1992.
Example of a function that would return an integer (how many months old) based on a persons age when given the date of birth?
View 1 RepliesI am creating a program that auto fill information. Now the problem is, that I have to fill in the Date of Birth, and it doesn't have the ID. How could I do that. (All must be automatically).Also I want it to choose at random, so if it choose 1, another time it would choose 2 or something like that.
View 11 RepliesMy project requires users to be 18+. I have supplied a textbox for birthdate entry, but I don't know if that's the best way. Also, I don't know how to format it so that it only accepts date entry.
Next is the calculation part... yikes.
today - bithday = age
Code:
Private Sub Birthday_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Birthday.TextChanged

If i double click on the dataset. i am not sure which statement to write to restrict the user so that he/she cannot enter the date in the past. i have droped the data set on the form and my data entry is through datagrid view.
View 13 RepliesI have a form that collects user parameters to print a report. There are two DateTimePickers to let the user select a date range for the report. The selection of a date range is optional so I set the From picker to a date before any data could be present. If the user wants to select a date range, the from field is set to a very old date so it takes a long time to get to any current dates. Whe I'd like to do is when the user drops down the picker, reset the date to today and let the user scroll from there.I tried the dropdown even in the picker, but the new date doesn't get set until the user has already selected a date. Any suggestions on how to get this type of UI behavior? Also any better suggestions to streamline the process?The main objective it to collect from and to dates from the user is they want to select them and collect wide ranging dates if the user doesn't enter any.

When I enter 4 digits whole number 7777 it is validating correctly showing message Enter Valid Date, but when I enter 5 digits 77777 it is accepting the value and converting it to 12/10/2112 value and not showing any error message.

How can I ensure that my program function can only run once a time per day? I wonder how did those commercial software that did something like 30 times/days trial. How did they store the value in the sense that altering the system date and time would not prolong the trial. Currently I am thinking of validating the date through internet time since it can't be alter by user. After which, I will store the value online. However, this does not seems to be feasible if its an offline application. I wonder is the any other better way to do it?

according to the assignment my program fills the requirements, however it's a real pita to constantly change the dates in the program every time I want to run different date values. Is there a way to have the user input a date? Initially I thought something like;
purchaseDate = new datetime(console.readline())
but this blows up. I get an error that sounds something like invalid data type cannot convert double to long... it's a very unhappy looking error heh
Anyhow, I've spent several hours digging through the MSDN Library but I'm not finding it which assumes it can be done in this format.
after reading a few other posts I don't want folks thinking I'm trying to be sly so...

Dim str1, str2 As String
Dim compare1 As Double

I'm not sure if this is possible, but if someone could explain as to why it might be happening.I have a form which has some textboxes: txtDateFrom txtDateTo Where the user would enter the date from and date to that he would like to search for. I've given these textboxes default values in their properties: e.g. txtDateFrom's text is 'Date From' and txtDateTo is 'Date To' . I've then added a onclick event to each of these text boxes informing them what format they need to enter the date :
[code]...
This method however seems to be invoked as soon as the form is opened, does putting a default value for a textbox invoke textchanged? surely not?
how I can ensure that conversion of a date to a string and a string to a date will give me the same date format.
For example:
Code:
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
Dim d As Date = Date.Now

I'm actually only interested in the date part as the label text shows so f is more than I want.But also, the day and month are reversed.

On the first check the correspsonding labels are handled properly but all the other labels are changed also, ie. the color changes on one set and the other set cleared.I can see the problem is in the Else If statements but can't understand why if the coding iswrong it works ok after the first check.

View 16 RepliesI am attempting to import data in a batch from an Excel Worksheet to a Sql Server database. Everything works except for the one date field in the spreadsheet. The date returned is off by four years from the value in the spreadsheet. Example: The Excel sheet has a date 10/24/2010 14:18, but when I look at the column in my query, the date is 10/23/2006 2:18. This pattern, 4 years and 1 day earlier, is repeated for every row in the worksheet.
The Excel column comes to me as a custom type, formatted m/d/yyyy h:mm. I receive this from an outside vendor and having them change the column is not going to be my simplest solution.
For what it's worth, the relevent part of the query is:

I can do this on the SQL side or the code side. I have Linq at my disposal if I need it. The table doesn't need to be compiled by SQL. This will happen dynamically on a website and should be as efficient as possible.I don't want to have to iterate through each and look for breaks in contiguous days if I don't have to.

That's what it looks like so far.
