Store Data To Access A Database?
Nov 28, 2010
I am using an Access database and vb.net 2010. I have created a table in the database with columns for title, datein, dateout and roomnymber. In vb.net 2010 I made a distinguished title = combobox, datein and dateout = DateTimePicker. When I click on F5, an error occurs: INSERT INTO Syntax Error in statement. Here's my code:
Dim sql As String
sql = "INSERT INTO tcekin(title,firstname,lastname,address,country,company,roomnumber,datein,dateout,rommtype,note)" & "VALUES('" & ComboBox1.Text & _

If you have to store and retrieve data from a database is a string not the most effcient way? What is best?
How does this work in a real world scenario.
For example: I have a customer ie first name and last name and the CustomerID is autoincremented when initially added to the database. Now, the user could lookup and find the customer by their ID but we all know that's not practical. They don't know 231223 is John Adams, they know John Adams or Adams John.
So how do you handle this? Access is the database I am using but I think this would apply to any database.

how to store a hash in my Access Database. Now I have generated a hash by salting a user password with the User ID (not highly secure I know, but plenty for my purposes). I have also stored the hashed values in the database as Base64 strings (manually, I haven't yet developed the module to do that automatically), however, when I go to retrieve the hash from the database I receive the hex code in place of the string. This is the code for the login button:
Sub prcLogin()
'Log User in
Dim ds As New DataSet
Dim blnCorrect As Boolean
[code]....
But when I run this instead of returning a value like "rlzhYoiO4+vpdJdsrFq5Sj9VBJ+FFYhIg9V5+z+jeNI=" which I stored in the database, it returns a value like "5C6BED0D94

I don't know if I can have several same forms to do the manager jobs, ACTUALLY THE STORE VALUES ARE DIFFERENT(those forms can have the independant data values to store into the forms), like if I can have the datagridviews to store the different values? SO,MY QUESTION IS if I can have several same forms(FROM ONE SAME FORM), and can store different data values into the forms with vb.net & access, OR I HAVE TO CREATE SEVERAL SAME FORMS.

I created a database (.mdf) file. I added data to it after running the program in debug mode. When I closed it and opened it up again, the data I got was stored and loaded again.I closed my whole Visual Basic Express program. When I opened it up again, all the data had disappeared.
Can you tell me what I am doing wrong with the program? I can't get queries to work either. It worked when I used the NOrthwind dataset this past weekend but it is not working when I use my own or empty dataset.

I have a process that's going to initially generate 3-4 million PDF files, and continue at the rate of 80K/day. They'll be pretty small (50K) each, but what I'm worried about is how to manage the total mass of files I'm generating for easy lookup. Some details:
I'll have some other steps to run once a file have been generated, and there will be a few servers participating, so I'll need to watch for files as they're generated.Once generated, the files will be available though a lookup process I've written. Essentially, I'll need to pull them based on an order number, which is unique per file.At any time, an existing order number may be resubmitted, and the generated file will need to overwrite the original copy.
Originally, I had planned to write these files all to a single directory on a NAS, but I realize this might not be a good idea, since there are millions of them and Windows might not handle a million-file-lookup very gracefully. I'm looking for some advice:
Is a single folder okay? The files will never be listed - they'll only be retrieved using a System.IO.File with a filename I've already determined.If I do a folder, can I watch for new files with a System.IO.DirectoryWatcher, even with that many files, or will it start to become sluggish with that many files?Should they be stored as BLOBs in a SQL Server database instead? Since I'll need to retrieve them by a reference value, maybe this makes more sense.

I am trying to import data from an access database to a access database that my project uses I am having problems with combo box fields in the database with the data. I want to import what is displayed instead of the numerical key value. Example: The combo box displays employee names but the value stored is the key value from the employee table so instead of importing John Doe it imports 2 is there a way to make the actual name instead of the number?
