I am working for application register form and I would like to know when the user opens the register form I need to check if the current date is true or not and when the user tries to change the system date he should pop up message.So I would like to refresh the form for every second and find whether he has changed the date or not. How do I do that?
Here is my code:
btnRegister.Enabled = False
Dim oReg As Microsoft.Win32.RegistryKey
oReg = Microsoft.Win32.Registry.CurrentUser.OpenSubKey("Software", True)
how can I create following thing with Visual basic?I would like my excel to check the date value in a cell and compare it to current date and if the value in the cell is older than 2 months compared to current date it would change the cell's colour.
I would need a function that would check the current date and in the end return the date of Monday this week. So say we have 02/06/10 today so I'd like that date or rather week_starting function to show 01/06/10 for the whole week. The formatting isn't important.
How can i check the system date format? Tried with the code below, but when i change my system's date format to another date format to test the code, it's still showing the date format before changed!
If DateTimePicker1.Value.Year <= DateTimePicker2.Value.Year Then 'dtp2 = expiry date If DateTimePicker1.Value.Month <= DateTimePicker2.Value.Month Then MsgBox("Expiry Date Correct!") Else MsgBox("Expiry Date incorrect!") End If End If
How would I get it to check the date? Datetimepicker1 is the current date, while Datetimepicker2 is the expiry date.
I need a function that would return true if the date provided was a payday or date of next few weeks paydays.Paydays are every 14 days on a Friday (not twice a month).I tried several attempts, but don't have a clue where to start, except that the function needs a reference date to calculate from.

This is my problem.I have a field set up in MS Access to Boolean YES/NO, this field is populated when the user check a checkbox on a windows form. If the user check a checkbox, the value is written as checked in the data field (MS Access).The problem is when I search for the user information, I need the information from the Data base to populate(return) to the windows form. Example: If I enter a users phone number and the user data is present, the form gets populated with the information the user previously entered which was store in the database.Example: If the user selected checkbox1 and submits the form. When I search for the user info, the check box should check(populate) because the user had checked it on submit.Here is what I have done:
[code]...
I am getting the check value correctly in the database using a Boolean.Here is one of the errors I am getting. Unable to cast object of type

I'm fairly new to ASP.NET & VB.I've been asked to take an existing textbox that is automatically filled with the current date and allow the user to either add a "+" or "-" and a number or a spcific number and convert that into a date.I underdstand the basic concept on how to do this, but I'm running into some problems using the proper commands in order for this to work.The Textbox is called txtDate.What I've tried to do is this:
If txtDate = '+' Or '-' Then DateAdd("d", txtDate, today) End If
Here is what the whole thing looks like:
Protected Sub DateEnter_Click(ByVal sender As[code].....

And if I want to search for the record which there are record that are insert five days earlier, how to do that ? use (datetime.now - 5) ?
I'm trying to compare the modify date of a file vs the current system date. I've found an MSDN article describing how to get the modify time of a file:
Dim infoReader As System.IO.FileInfo infoReader = My.Computer.FileSystem.GetFileInfo("C: estfile.txt") MsgBox("File was last modified on " & infoReader.LastWriteTime)
This gest the Date and Time, but I want just the Date not the time.
I'm trying to check if a bit retrieved from database is true or false but i have always the error IndexOutOfRangeException no matter how i get the value.
Nice simple one (I Hope) to start of the day. I have got a load of calculations going on and then a set of rules being checked after the calculations. I then have 9 booleans which check against the varibles. Basically I would like an easy way to check how many Booleans are False and how many are True.
I'm testing with 2 buttons on form, at the form level i have set: Dim btnIsClicked As Boolean = False if a button is clicked in the click event i then set the boolean to true, but is there a way i can check in another event whether the values has been set to true?
I want to store true or false value based on the state of check box here is my insert statement, the problem is this this insert statement stores 1 or 0 instead of 1 or 0 i want to store true or false how to achieve this. [code]
I have a date in the future e.g. 13/10/2008 I need to subtract the current date (today is the 28/09/2010) minus 7 days, so thats 21/09/2010 minus 13/10/2008, which would equal erm, 720 something ? But the current date won't always be 28/09/2010, obviously. I need the code for this. EDIT: When i said future I mean past :)
Example For each PolicyNumber i have 5 NextPremiumDates.I want to display the 1st NextPremiumDate which is easy ...but i want to show the next NextPremiumDate only after the last NextPremiumDate has passed...How do i check if the last date has passed?I mean if i have 5 dates in the table given above...how do i check if the 1st date has passed then show 2nd date ...if 2nd has passed show 3rd and so on.
I have code which saves DGV contents including check box columns as a comma separated text file. I also have correct code which will take the text file and re-insert it into the DGV at a later time. This all works.When I'm working on the DGV, I have this
Private Sub DataGridView1_CellValueChanged(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellValueChanged If DataGridView1.Columns(e.ColumnIndex).Name = "Column12" Then[code]....
So that when the check box is true, columns 1 and 3 turn different colours, and when false, go to a yellow colour.However, when I "re-insert" my DGV info from my text file, the check boxes come back correctly - as true and false on the right rows - but columns 1 and 3 don't change colour. I've tried a "DataGridView1.Refresh" option but not getting it to work.The DGV is unbound. I need it to recognise which check boxes are true and update automatically when the information is opened from a text file.
How do you get the current date "2/23/09" but you will only display the day for to day which is "23"? What is the code to format the date that will display only the day for the date today.
Either I just can't seem to find the right way to word the problem or it's a lot more complicated than I thought, but what is the easiest way to assign the current date to a variable and format it to a specific format? Basically, I want to do the VB.net equivalent of this VBA line:
I am working on an app with the datetimepicker. I have everything working but wanted to go one step further and have the current date show when the app is opened up. Is this possible? Or does it always default to the date in the properties? When I reset the form I can get the current date to show.
whenever i have my date column sorted, and i add a date that needs to be sorted into the current dates, the datagrid does sort it properly, however, that last date in the datagrid always adopts the date of the newly added date. [code]
i have a table "Contracts", with fields CompanyNumber, MaturityDate and other fields.i have a form in vb.net, with a textbox that should check if the entered company number exist in my db, if it does it should check whether the maturity date is bigger or less than current date.Any one out there that knows how to go about it? Here is the code am trying with;
Private bindingSource1 As New BindingSource() Private dataAdapter As New OleDbDataAdapter() Dim connectionString As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=mtc.mdb"
a function to get wither the current date is a weekend or not what i need is to make the Word "DayOfWeek" is variable For Example I want to remove it and replace it with X which will be detrimined on run time by user
