Displaying Current "Real" Date And Time In Windows Form?
Jan 28, 2011
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.

I've got a module for my program thats displays the active time and date, on a form. For some reason my code is incorrect and nothing happens when I run the form. Heres the code I have in the module:
Module ModDateAndTime
'Declares tmrdat as a timer with events
Public WithEvents tmrdat As Timer
'declares lbldat as a label
Public lbldat As Label
[Code] .....
And the code in the form's:
'declares lbldat as lbldateandtime
lbldat = lblDateandTime
The relevant label in the form is named lblDateandTime

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've already wrote a simple program for connecting to a serial port that can send data to the microcontroller, do some basic arithmatic and transmit it back to my Form. This was just to see if I could set up the conection.I have a PIC Microcontroller giving an 8-bit number thats is taken from an external sensor device.What I want to do now is to present this data from the microcontroller in a textbox as a number either in real time (as the sensor output changes) or if not possible, on request (using a button).

I'm having a bit of an issue receiving a stream of serial data and displaying the data real-time in my GUI. I am fairly new to VB.Here's what I'm trying to achieve: I have an I2C device (bank of LED's) connected to my Arduino. Using the VB.NET (2010) GUI I request which LED I want on (via buttons) and the I2C device then sends a reply confirming which LED actually turned on (basic feedback). Ok, sounds great right? Here's where I get issues. Well when I try to read the serial data sent to VB and display the real-time stream on the GUI, a) I get a bit of a mess as an output (values are ok, just spewn across GUI) and b) when I select a new LED to turn on, the GUI data does not refresh to this change. The stream being sent from the Arduino is ok, I looked at the data in a serial monitor.

I am busy with a VB2008 EXPRESS program that reads is data via a network cable. Saving the data on the same computer as my program is not a problem, but I must also make this data available to other users in the network and update their screens in real time. In other words I need a COPY of my running program on each networked computer when requested by the user in the network. I have looked at SQL, XML pages and inheritance. But I am confused, what is the best way???

I have a windows form where I want the time to constantly be updated. Right now it will take the current time from when the program was started.
For example, if I started the program at 4:30:29 PM that is what it will show the whole time the program runs.I need it to constantly be updated as the seconds tick by. So, If I started the program at 4:30:29 PM and ran it for exactly 5 minutes, the time displayed then should be 4:35:29 PM.The data being taken in and saved needs a time associated with it and the end user also need to know the current time as the program is ran in full-screen.

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.

My current program is reading a XML doc and using it then moving it to a different directory to be archived once it is finished using the xml.
I want to be able (upon completion) move and rename the file to a new folder, I want the folder to be the current date/time as well.
So basically have 4/4/2011 9:56AM.xml in the folder 4/4/2011 9:56AM.
getting the function DateTime.Now in a format that can be saved. Folders and files cannot contain the " / " or " : "
A more Sql server type of date would be fine like 24-Jun-89 13:32:22 but I don't know how to get something like that.

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 an app that I'm trying to keep single threaded, mostly for reasons to do with simplicity of ongoing maintenance. I've structured it so that I can eventually multi-thread it if need be but I'd rather not at this point. It's semi-real time and does perpetual looping to display a number of different graphs and do various work with both the graph display and the work being hosted in their own respective objects. If you're familiar with the Windows dispatch manager it's that general paradigm run synchronously. And yee haw, it pretty much works at this point and runs fast enough to meet requirements by a happy margin. I have a cosmetic problem that I'd like to solve if I could. When I left-click and move any form around, my graphs stop updating until I release the left click button. I was thinking about a doevents somewhere in the click event catalog.
