DataGridView DateTime Colomn (Also) Passes Current Date When Only Entering Time
Apr 19, 2010
I am building an application that needs to store different time of day values in dateTime fields of an Access database.I am trying to enter the time value's via a DataGridView using TextBoxColomn s.The coloms are formatted with the defaultCellStyle property to show only the time part of the datetime.After i save the entered data and look in the database itself, i see not only the time, but also the (current) date in the datetimefields. This raises a problem when i want to compare the timevalues later on in the functionality of the program i am building.(Of course it is simple to seperate the date and time part in coding of the program, but it would be more elegant (i think) if i could just save only the time part in the database (and have the date part of de datetimes left to 0))I have tryed via the CellFormatting and the CellParsing events, but no luck.I am new to visual basic and probebly missing out on something.
I have two datetime variables in VB.Net [code]I want to add both these variable in single DateTime variable , i didn't find any .Net function to do that.Is there any other way to do it?
I'm getting date-time from a source as 20110731183330. I want to convert it to '7/31/2011 06:33:30 PM'. Is there a one line code for the same in vb.net?
I'm trying to create an auction site using asp.net. My auction's start date & time and end date & time are stored in my sql server 2008 r2 database as datetime types. I'm using vb.net. I'm trying to create a select statement in which I can query the date and time portion relative to the current date and time (so as to only display current ongoing auctions). I can successfully query the date portion using the Date.Now function, but the time is giving me a hassle. DateAndTime.Now doesn't work. I've even tried to separate the time and date in the database, but I still can't get an effective query. Here are two examples of code which I've tried:
Is there a framework class that converts the partial day strings on these forums to a DateTime? Examples are "a few seconds ago", "19 minutes ago" and 3" hours 26 minutes ago",
How can I have a Folder created with the Current Date and Time as iets Name and at the same time Save a Picture into that newly created Folder. Here is the code I am trying to get to work.

In OrderDate text box, default date is today (e.g. 05/19/2010). Once user change it, how to code to save to SQL server as DateTime format? For example, user may change OrderDate as "05/12/2010" but will save it as "05/12/2010 09:17 AM" (time is current time)

I have a 500K+ lines vb.net app, written by 10+ different devs over the past 5 years. Many times it gets the system time and/or date and relies on it.Now I have to re-run real cases thru the program for regression testing purposes, and it screws up cases where the date/time matter. My fix is easy, just replace all the areas in the program that get current date/time with a sub that gets the current date/time, UNLESS I'm testing, in which case it will return the date/time of the original run. I have tried searching the sourcecode for the obvious 'current date/time' functions:
Now DateAndTime.TimeOfDay Date.ToDay
However, if I miss one, I LOSE.list more ways to get the current time, that might be hidden in the source code, that I can search for? Note: It's pretty clear none of the 3rd party libs in this system are returning date, well, one is, but I've caught it.
I have written some code that generates an output file from an external executable. I would like to insert the current date and time into the resulting filename. In the pi.Arguments line (shown below) the /l= creates the output file. I would like the name of the file to be Trustee_Restore_YYYYMMDD_HHMMSS.TXT.
Private Sub Button5_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button5.Click Dim p As New Process Dim pi As New ProcessStartInfo
[code]....
Everything works, except I would like to insert the date into the output filename.
adding basically just the current date and time to a textbox/label or something like that? I have looked at coding but everyone seems to do it in such a complex way. Is there not a simple way of doing this? I don't want to use the date time picker as I don't want a user to be able to select the date or time.
I am doing work on a new logging database that I have decided to use UTC datetime to store all datetime values since our company spans timezones and multiple sources and timezones are logging events.However the problem that I cannot get my head around is formatting the datetimes in my datagridview for my user application.Our applications use mostly LINQ to SQL to manipulate our data from generic SQL CRUD calls, so I am hoping I can mask/format the DGV to get the conversion or some LINQ function rather than having to write special SQL stored procedures to do it every time I need to display the data.. (I have found multiple sources that explain how to do that)
I am trying to write a program that shows the user the current system time and date using progress bars in VB 08 Express but don't know how to start it, I am having trouble with getting the program to refresh the minutes and seconds progress bars
I'm trying to match a certain DateTime value with the current system DateTime. I have a timer and a label on a form. Timer interval is set to 1000. When the form loads, the timer starts ticking. As soon as the current DateTime matches the value of the variable, it shows a message in the label. When I'm writing the following code, the values don't match even if the current system DateTime is equal to the variable. Label1 isn't showing 'Times Matched':[code]The default format of 'Now' is the same as I have stored in dtmVar variable. So there's no question of format mismatch. Does that mean 'Now' is not actually a DateTime property? Provided, my O.S. is Windows Vista Ultimate and all date/time settings are set to default.

I have got a MySQL database that has got some dates stored in a Date format (YYYY-MM-DD) however when i try and import the data i get an error saying: "Unable to convert MySQL date/time value to System.DateTime"
how you display a live or current date and time on a Windows for application.
I am working with Visual Basic 2008(VS Studio 2008).
Example: January 28, 2011 8:00AM.
I have several books, strangely this subject is not properly covered.
This is my
Private Sub lblDisplayDateTime_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles lblDisplayDateTime.Click Dim currentDateTime As Date = #8/2/2007 1:02:00 PM#
[Code]....
Finally, how do I make the time load when the form runs? I can't seem to find an event, that allows the time to display when I run the form. Currently, I have to click the area containing the label to get the time to display.
