Microsoft Access Database From VB6 - Vista - Run As Administrator - Different Date / Time Stamp?
Mar 27, 2010
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).

Does VB9 provide a compile-time date/time stamp function? I know VB6 did not; I'm hoping VB9 does.

I can save my data to access database and in the access database field I set it to date/time.But problem is when I get the value out from the database.. the format is always month/day/year hour:minutes:seconds example today: 5/2/2011 12:00:00..How to get the value into listview becoming May/2/2011 without the hour..Here's my code to get it from database ListView1.Items(i).SubItems.Add(dt.Rows(i)(14).ToString).The second problem is.When I would like to edit, how can the datetimepicker get the listview value ? [code] info: using access 2003 (.mdb) the Date of Birth field has been set into Date/Time.

I'm using ASP.NET/VB and I'm trying to insert a date and time into an Access date/time field, but I'm getting an error (Data type mismatch in criteria expression). Here's a simplified version of my code:
Dim myDate As Date = Now()
Dim myIns1 As New OleDbCommand("INSERT INTO tableCourse (date_submitted) VALUES (?)", myConn)
myIns1.Parameters.AddWithValue("@myDate", myDate)
myIns1.ExecuteNonQuery()
Not sure why I'm getting the error, and not quite sure if this is even the correct way to approach inserting the current date. From looking at other similar questions it appears there are a few different ways to do this, but my technical knowledge is kind of limited so I'm having a hard time figuring it out (in other words deciphering the answers that use technical terms I know nothing about).

I have an ActiveX EXE that is compiled with VB6, unfortunately because it exposes an ActiveX interface it refuses to run unless i embedd a manifest file into it requesting elevation priviliges of administrator.This in turn has the side effect of VISTA prompting the user to logon as administrator each time they run the application.The admin on site has already refused to disable UAC.Is there any way for either our application or the administrator to auto-elevate the program on the domain?

We have developed a 'deployment tool' (say program A) which need to modify system registry, etc info which requires admin rights. This program will be triggered by another program (say program B).
Question, when B call A, how can B initiate A with admin rights? is there any command like A.exe /runas admin or any other way to achieve this. Please note that both programs are developed using VB6.

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")

I have vb .net windows form application that I want to connect to Microsoft access database using "Microsoft DAO 3.6 object library". My problem is that when I go to Project tab -> Add reference -> COM tab, there should have been "Microsoft DAO 3.6 Object Library" on the list, but for some reason It's not on the list. Then I googled, and found out that the location of "DAO360.DLL" is "Program FilesCommon FilesMicrosoft SharedDAO". After clicking on Browse tab, I browsed to that location, and I guess I added reference on another way.This is the code that I used before for connecting to Access, but for some reason It doesn't work this way on this PC.

We are working on an ASP.Net/VB.Net application using Enterprise Library for our data access (DAAB).
We are trying to store DateTime values in an Oracle Date field. However, the precision is being lost. Currently only the year, month, and date are being stored. We need better precision than this.
Oracle Dates are supposed to "includes not just the month, day, and year, but also
the hour, minute, and second. "

I 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.

I 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?

I am writting an application that stores data in an Access database. I can't put the files in the Program Files directory since standard users can't write to that folder. I can't use a 'user' folder since multiple users will need to access the same file. In addition to accessing the file, users on occassion will copy new versions of the file into the folder, overwritting the old file.Where should I put this file? I am thinking the ProgramData folder, but when I create that folder during the install, it is also read-only for a standard user.I'm lost as to where I should put a file that can be accessed by multiple users, that is read/write, and I can install the folder into the location. I don't think I have a programmatic way of installing a file into the Public users folder.

I posted this as a bug on MS Connect and am wondering if anybody else can verify the problem: I been beating my head against the wall for about 3 days and I don't think it is my problem.
Desktop computer - Vista 64 bit
Portable Computer - Vista 32 bit
vb.net 2010 express on both of them
I can not establish a connection to an Access db (either .mdb OR .accdb) on the 64 bit computer. When I try I keep getting a message that says "Format at the initialization string does not conform to specification starting at index 0." (this was typed not copied). (There are screen shots over on Connect).
I can establish a connection to a "Microsoft SQL Server Compact Edition" (.sdf) database on the 64 bit computer.I can estabish a connection to all 3 types on the 32 bit computer (.sdf, .mdb, .accdb).The 'funny' thing is that if I establish the connection on the 32 bit and copy the program directory over to the 64 bit, the prorgam loads and seems to run fine. But the %$# _(%* Wizard will not run on the 64 bit machine. Runs fine on the 32 bit but not on the 64 bit. Of course I make sure that the db's are in the location where the program expects them to be when I run the program on the 64 bit machine.
One final thing, when I am in the progam created on the 32 bit and running on the 64 bit and I try Data->Add New Data Source->Database->Dataset only two of the three connections show up while all 3 show up on the 32 bit machine. Also the connection string is incorrect for the non-sdf connection. It should include

im just starting to work with some database stuff, and ive got data binding done but im a little stuck with filtering. Ive got a test project, which has
-- listbox (bound to column 2/firstname)
-- Combo box (Has items added, with the same names as the items in colunm 3. so it has 'RPG' and 'Puzzle')
Now what im trying to do is when the item in the combobox is changed say to 'RPG' only items in the db which have 'RPG' in the surname column are displayed in the listbox. Been Google'ing and reading but all i can find is examples relating to a dataview and i cant get them to work/adapt to my situation.
