VS 2008 Datetimepicker Value Needs 2 Digit Day
Nov 11, 2009
How can I get the datetimepicker value to have a 2 digit day EX. If it was November 6, 2009 the value is showing as 11/6/2009 but I need it to be 11/06/2009
I have a search that searches by date and Im using the datetimepicker. the date format in from my sql database is in MM/DD/YYYY not MM/D/YYYY So my results come up ok if the day is a 2 digit day normally (ex. 11/20/2009)but if its a single date (11/6/2009) I don't get any results because it is looking for 11/06/2009 I don't see how I can get the value of datetimepicker to be MM/DD/YYYY Even if i set the custom format to MM/dd/yyyy the value is showing up as MM/d/yyyy

I just finished this application where you enter a five-digit credit card number, with the fifth digit being the check digit. everything seems to work except, I can't seem to get it to determine that any number is "valid". Every 5-digit combination that I enter returns "The credit card number is not valid". Im using visual basic 2008 express

I'm supposed to write a program that validates an inputted ten digit ISBN number using the check-digit at the end to ensure that the sum is a multiple of eleven. Before calculating this and detecting if the entered number is indeed a valid ISBN, we're required to check the first nine digits and see if they are indeed integers. After this the tenth digit is checked to see if it is "X" (for ten) or 0-9.
With the code I've written it keeps returning false for whether or not the ISBN is valid, even with valid numbers. I feel like its something to do with the hyphens; have I misused the replace function?I'm a little lost on how to make my code work, but I'm fairly certain my logic is okay so far.

I'm making a project that randomly picks a number from an array, but if it picks a number less than 10 then the number is a single instead of a double.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim N(2) As Integer
N(0) = "0" & 1
N(1) = "0" & 2
N(2) = "0" & 3

I'm using Visual Studio and table adapters using an Access DB as the backend. I need the minimum 4 digit value. I want to get next available 4 or 5 digit number. And this will change depending upon the users request. Currently I use a table adabpter query. But how would I write a query. I suppose I could do a long iterative loop through all values until I see a 4 digit.But I'm trying to think of something more efficient.
Function GetNextAvailableNumber(NumofDigits) as Long

Does anyone know what is the best way to check has datetimepicker been clicked and value selected before saving and updating database. I am working on a database app and database field for "Date" does not allow null so in order for app to work properly i would like before saving to check if the date is selected and if not to create warning for user. I have created that for "Name" and other columns, but those are text boxes so I had no problem with that. I could change the database field for "Date" to allow null, but that the easyer way and not what I really want. If someone has solution for problem

I am having trouble with the datetimepicker. I use this and I tried as many as I could but didn't get a proper result, this one is the closest, so atleast while debugging I can see it having the right value:
datePContBDay.Value = dsn.Tables(0).Rows(0)("PContDOB")
But all it shows is todays date, don't know why?

I am working VB.NET 08 Access Database. I have Two "DateTimePicker" controls one is "StartDate" and one is "Enddate". Now I am selecting Startdate like May 1st OK. Now when I select Enddate control this calender shows only Equal or Greater than dates should be Enable. EndDate should be Always Greater than Equal Date. That's why when ever user selects the Enddate Before May 1st dates should be disable..

Wasn't really sure what to name this thread or how to explain it. I have a form with a dateTimePicker control on, textbox for days, button and label, when the button is pressed I'd like the amount of days put into the textbox to be added to the value in the datetimpicker then the result being put into the label.
E.g. Select 26th November in the DTP, then put 6 into the textbox, press the button then have 2nd December come out in the label. I've tried a few things but all fails and just gives me back the original value in the DTP.

We have this custom DateTimePicker in our project where you can alter the BackColor and so on. But normally, when you click on the month of a DateTimePicker, it gets highlighted and you can change it with for example the arrow buttons on your keyboard or by typing a different number. Now the problem is that in our DateTimePicker, the highlighting doesn't happen anymore. When you click on for example month, you'll be able to change month but you don't see wether you selected month or something else.
This is the code we have (it's old code from way before I even started working here):
Public Class ucBaseDateTimePicker
Inherits System.Windows.Forms.DateTimePicker
' true, when no date shall be displayed (empty DateTimePicker)

I just been working with datetimepicker and I can't get it working if it is unchecked. When it is unchecked looks like it is not taking anything in. I can't load the value in it if it is unchecked which I need to have unchecked until the user ticks it by selecting the date.even if I am trying to trick it by doing this:
dtpCallback.Checked = True
If (Convert.IsDBNull(dsOrders.Tables(0).Rows(0)("callbackDate"))) Then
Else

Im trying to change or increment the month value of the datetimepicker using a command button. I tried to use the sample code from MSDN site but I was only able to increment once. I want to increment the value of the month everytime you click the command button. Do I need to use a loop statement? If so, how do I do that? I used this code below which can only increment or change the month value once but when you click the button again, no changes will be shown.
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
'DateTimePicker2.Value = New DateTime(2001, 10, 20)
DateTimePicker2.Value = New DateTime(DateTimePicker2.Value.Year, DateTimePicker1.Value.Month + 1, DateTimePicker2.Value.Day)
End Sub
