Masked TextBox Validation - Today And Tomorrow Date?
Jun 9, 2011
The user can only input today's date and tomorrow's date. How can I get it? Example valid dates are: Today's date: March 01, 2011 and tomorrow's date: March 02, 2011 if the dates are not valid then error.
Dim DD As String : Dim MM As String : Dim YYYY As String
Dim DDMMYYY As String
DD = Now.Day : MM = Now.Month : YYYY = Now.Year
If DD.Length = 1 Then DD = 0 & DD
If MM.Length = 1 Then MM = 0 & MM
DDMMYYY = MM & "/" & DD & "/" & YYYY
MskTxtBoxDate.Text = DDMMYYY
I am trying to mkae sure that there has been 16 numeric digits entered into the masked textbox. If not show errror message and if so to call the fucnction ValidateLuhn. When calling Validate Luhn i want the program to tell me if the number entered is valid or invalid using the code in the function:
Private Function ValidateLuhn(ByVal value As String) As Boolean
Dim CheckSum As Integer = 0 Dim DoubleFlag As Boolean = (value.Length Mod 2 = 0)
OK, so i was going to verify a MaskedTextBox on whether the number input was or was not 10 digits in length. If not 10 digits, obviously they didn't put in a full phone number.
The problem is, even though you have no digits the length is still 10 so you can't check if the user put in 10 digits or not and return an error? Anyone got any ideas on testing for a phone number?I've seen tons of examples on date verification, but none on phone number verification.
I have a function i'm using to validate some textboxes. However, the zip code masked textbox validation is not working. Zip code cannot be missing any of the first five digits (the last four digits are always optional). Here is the code that is not working. [code] Also, I have a menu item which when clicked will pop up a font dialog box. When i select a font, it is supposed to changed the font of every control on the form. However, it is not working. [code]
I have a textbox that get the date from the system itself, is working good and I have another textbox that will get the date that the person needs to bring the Book back. I wont the person to type the date but the program do it automatically (something like 20/04/2009 + four days=24/04/2009) automatically, something like if the person took the book on todaydate(20/04/2009) the function add more 3 days and display on textboxreturn( 24/04/2009). I don't want the person to type the return date, but to build a function that do it.... 0&1Bytes
I have a dataSet that I am using to populate a masked text box field. The mask is set to ShortDate ("00/00/0000") but when the number is inserted into the text box it is not formatted correctly and is inserted and the date 2004-04-07 looks like 47/20/04 1 in the masked text box.
We have a very massive system where reports are run off dates from specific days through to today's date using various definitions of "GenerateSalesReport(DateStart, Date.Now)". For debugging purposes I want to simulate reports that occurred in the past so I need to change the object "Date.Now" to a specific date from the past on my development environment. Can you override date.Now?
i'm doing a project for school which requires me to make a fully functioning database program with validation.

As the properties Value of the date/time picker does not allow to enter the DateTime.Now default value, I have tried to set it in the code:[code]It indeed shows the current date on opening the form with the date/time picker.However one cannot set any other date from the drop down calendar (one can choose a date, what means that the calendar is dropped down allowing to point a date, but after clicking the choice the date/time picker value returns to the current date).

When populating the data into a date masked text box for display, I am not getting the zeros in front of the month and day resulting in the date 07/02/1974 displaying as 72/19/74.
How do I insure the month and day have the correct format before the masked tb gets filled. The data type in SQL is small date and displays in the table as 1974-07-02 vS2008 / SQL2008
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.
I have a process which grabs the birthdate and from a data table and display them in a masked text box for viewing and editing However when pushing the data into the textbox any preceding zeros get removed For example 05/05/2005 would display as 55/20/05__
The masked Text box is set up as 00/00/0000 The line which assigns the code is:
I have wrote a function which validates a masked exit box date format. I have entered into the Mask property 00/00/0000 which on screen translates to __/__/____, great. If I get an invalid date I want to clear the content and reset the focus back giving a message box warning. [code]It all seems to work until I then try to enter a new date. The first number a press seems to push the mask characters to the right and then the rest works. So if I entered 01/01/2009 I end up with _1/01/2009.
i wanna know about the main characters on Masked text box and meaning of them like CCCC, L, ?, 000, 999 and the second question is how i can use masked box to make user type a valid EMAIL.
