Record Of Values Changing Over Time With A Datetime Stamp?
Aug 22, 2010I have been dabbling in VB before and i played around wiht linq to sql back then but im wondering what i should go with here.I need to have a list of people.. They should all have their own id nr.
The people in the list are supposed to keep a record of values changing over time with a datetime stamp. (In my case its numbers from a test outcome of blood)You have to be able to add people and delete people. All records will be deleted too.A Chart will read information from the records and display changes over time in chart.I was thinking of doing it with linq to sql and i was kinda aiming at Creating datatables with id names from the script
Havent found a way of creating datatables from a script though..I was hoping for a solution like that.. And i was hoping id be able to search databasetable names.

View 2 RepliesHow To Rename Existing File With Date Stamp
May 28, 2012I understand how to rename a file in vb.net as I use the coding at the end of my post. However, is its possible to rename a file and if the file exists then to rename it and add +1 to the file name? So if I ran the code.
'Run it first time
My.Computer.FileSystem.RenameFile("c: est est.txt", "c: estNewName.txt")
'Run it again but it should add +1 as the file will already exists so it should be "c: estNewName1.txt"
My.Computer.FileSystem.RenameFile("c: est est.txt", "c: estNewName.txt")
Decided rather than rename and +1 it would be better to just date stamp it.
My.Computer.FileSystem.RenameFile("c: est est.txt", "Test" & Format(Date.Now, "ddMMyy") & ".txt")

View 2 RepliesUsing A Text Box To Display The V_KEY Code And Time Stamp It?
Jan 15, 2012I have a really interesting task I need to code and I'm stuck. The application I'm creating Takes the mute button on my laptop and triggers an even when the mute button is pressed.
The issue is I found when the mute button is pressed, the computer sends the v_key code for volume down in a rapid rate. What I want to do is display the v_key code and a time stamp in a text box:
When I press the mute key, the v_key code and time stamp are displayed for every instance that code is thrown. The same goes for un-mute.I'm having issues with my application not triggering the event when the mute is pressed because the computer is shooting out the v_key code so many times, so fast.
My plan is to create a kind of de-bounce logic- IF the v_key code is detected x amount of times in y timespan then.To do this I need to know how fast and how many times this code is occuring.
Any direction or ideas on how to go about this?

View 8 RepliesMicrosoft Access Database From VB6 - Vista - Run As Administrator - Different Date / Time Stamp?
Mar 27, 2010I have a VB6 application which has been running succesfully for years under XP, however under Vista data loss has been observed.It appears that if the app is run 'as administrator' then it connects to the correct database file, however if the app. is not run as administrator then vista creates a copy of the database (no idea where) - hence I end up with 2 versions of the database.
In fact I can delete the database file entirely and the app. still works fine because vista is using it's own copy - the problem is how do I back up this 'vista copy' when I can't find it (search doesn't find it).

View 3 RepliesMatch A Certain DateTime Value With Current System DateTime
May 7, 2010I'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.

Dec 27, 2010I try to compare Datetime.Now with a Datetime variable I set, using the Datetime.CompareTo() method. I use a timer to compare these every second and display the result, but as the current time approaches the time I set, the result changes from 1 to -1, but never 0, which means these two are never equal. I'm suspecting the Datetime structure contains milliseconds?

C# - Using .net Datetime In Sql Query
Mar 31, 2010I have a DateTime object I want to compare against an sql datetime field in a where clause. I'm currently using:
"where (convert( dateTime, '" & datetimeVariable.ToString & "',103) <= DatetimeField)"
But I believe datetimeVariable.ToString will return a different value depending on the culture where the system is running.
How would you handle this so it is culture independent?
EDIT : I won't be using paramatised sql in this code...
EDIT : following Parmesan's comment to one of the answers looks like the best method may be:
"where (convert( dateTime, '" & datetimeVariable.ToString( "s" ) & "',126) <= DatetimeField)"
