My code is as follows:ComboBox1.Text.ToUpper() & "', '" & TextBox1.Text & "', '" & Now() & "'"Where the comboBox populates the first field, the textbox populates the second and in the third I get 0000-00-00 00:00:00.

I 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).
Am using visual studio 2010 vb. Using .net have added a reference to microsoft.office.interop.outlook type=.net version 12.0.0.0 copy local = false path = ...microsoft visual studio 10.0/../pia/office12 Using regasm.exe microsoft.office.interop.outlook.dll I have registered this assembly. Using the /regfile option I have viewed the contents. The clsID that it can't find ( CLSID={0006308B-0000-0000-C000-000000000046}) is not in this regfile. I would think that it should be.This classID on the MSDN site brings me to the Office 2010 Outlook.Namespace Class. For Office 2007 no clSID is listed.In the GAC there is microsoft.office.interop.outlook.dll version 12.0.0.0 is registered.When I run my application I get the above runtime exception.

View 1 RepliesI'm having a problem with a MySQL query for returning the "last visit" field in a table.Originally I had:select fname, lname, last_visit from patient where isactive = 1 and uid = 1Which worked perfectly in MySQL, but as soon as the query is executed by my ASP.NET app, it adds in the time field also to the date area.

I 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 10 RepliesI 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 RepliesI 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?

Thought I'd see if Stack overflow is quicker than me testing something while I get a thousand interruptions from other work :)
I'm updating an old VB net application and trying to refactor some of the logic as I go. The app looks for data from a single date across a few tables and writes that view to a file.
Writing the query in SQL I'd get the equivalent of
SELECT * FROM table
WHERE CAST(FLOOR(CAST(table.date AS float))AS datetime) = '15-Jul-2010'
Ideally I'd use
SELECT * FROM table WHERE date=@input
and add a date object as a parameter to a System.Data.SqlClient.SqlCommand instance
Are those two comparable? Will I get the results I expect?
