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:
formatted_date = Format(Date, "yyyy-m-d")
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

View 3 RepliesI'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.
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.

View 6 Replieshave a really annoying VB 2008 problem and I'm hoping someone knows how to solve this. I implement the following code:
Code:
DispArrDate = MonthArr & "/" & DayArr & "/" & YearArr
DisplayArrDate.Text = DispArrDate.ToLongDateString
So basically, I'm getting date information from the user and trying to convert it into a date format, and show it to the user in a text box which is obviously named "DisplayArrDate", and "DispArrDate" is a date variable and "MonthArr" & "DayArr" & "YearArr" are strings which are always numbers because they are selected from a drop down combo box.
Now, the code works perfectly on my computer and some others, but for some unknown reason, on some computers, even if they have the same local date settings, it gives me the error: "Conversion from string "4/13/2009" to type 'Date' is not valid.", that's just one example, where "13" is obviously the day. I use the month/day/year format because, in the toturial I'm reading, it tells me, that no matter my local date settings, when using VB 2008, the month/day/year format should always be used and it will display a date in the local format automatically. It seems that on some computers, this isn't the case, and the month/day format is creating errors.

I'm try to come up with a way for a user to enter a date and time into a textbox and for that value to be saved as a datetime variable back into a database. I'm wondering if anyone knows of a clever way to restrict what values a the user can enter so that the datetime datatype isn't corrupted. I've been playing around with the date time picker but I cannot seem to get that to work for me. I'd like the user to either pick the date and time from a picker and save that into a variable. Or I've seen applications where the textbox will automatically have a formatting type of template that makes it hard for the user to enter an invalid date and time.

I am trying to format a date from a table that I'm getting so that I can concatenate it with another string.But I want the leading zero - I don't want 1/1/2009 - I want 01/01/2009.
I can't seem to find a formatting pattern that does this.
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 :)
