VS 2008 Updating A Access Db From An Arraylist?
Jun 30, 2010I have a access db that contains logs in it from a project of mine. I have set up a total of 10 columns per row for log ids to be inserted ex: Log_1, Log_2, Log_3, etc...
The logs are pulled from an XML file that I downloaded and extracted from in an array list: log_id_1, log_id_2, log_id_3, etc...The db columns are a fixed number, 10. While the log id in the array list are variable, from either none upwards to about 20 of them.
If my arraylist has more entries in it than db has positions, I dont get an error, but if my array list has fewer than the 10 fixed columns in the db, I get an index error.What should I do to fix the error, capture the error and ignore it or is there another, better method?

VS 2008 : Updating Access Database Using DataGridView1?
Jun 18, 2012I'm having trouble updating my access database using DataGridView1 on my form. I created a DataGridView on my form linking it to an access database data source. At run time, the DataGridView shows the content of my access database. When I edit the database data in DataGridView, it looks like the database is being updated but when I close the form and reopen, the database is not updated. Do I have to write code and assign it to a button to update the access database? Is there a way to update the database once a new value is entered in the DataGridView? Am I missing a setting that does this automatically?

View 1 RepliesVB Express 2008 -> Access 2007 Updating Items Slow?
Jun 12, 2011I'm using Visual Basic Express 2008 to create an interface with a order database in MS Access 2007 (.accdb file). Everything is fully functional except updating the "Inventory" table is very slow. Updating around 2200 items takes almost 2 minutes and the window will appear as "not responding" for the duration if you click away and come back. Here is the process:1. Tab-delimited text file is picked by user, which includes all inventory items (not just new ones)2. Each line from text is parsed and read into variables (tempSKU, tempItemTitle, etc.)3. Old items are updated and new ones are added. -> This is the bottleneck
I used to have a series of IF statements to check which elements were changed and report them, but that was about 2x as slow. The new code is a little faster but doesn't provide the feedback I liked (update part is commented around):

VS 2008 Updating A Single Column, Multiple Rows In An Access Database?
Aug 25, 2010I have an access table that I'm loading into a dataset, then I'm binding the dataset to a bindingsource. The bindingsource is the datasource for a datagridview. I can use a command builder to update the entire table, but I need to update all the rows (or changed rows) in specific columns. I have a column called "dPrint" which is Boolean. I'm not sure how to use the bindingsource as my datasource in an Update Command. I've tried this:

The actual error it gives me is "InvalidOperationException was unhandled". Here is my code (ask me questions for any clarification):

View 2 RepliesBatch Updating Of An Access Database (DDL)?
Jan 27, 2012I have taken over support of a VB .Net application that makes use of an Access database. Now I discover that the developer who wrote this application did not create any unique indexes on the primary key columns for the tables in the database. So none of the primary key fields are actually flagged as being primary keys in access and so no duplicate checking is being performed by Access. Furthermore, the primary key columns are not being auto-incremented with an AutoNumber type in Access, rather the developer has used queries like this to insert rows into the tables:
INSERT INTO Users (pkid, FirstName, Surname, City)SELECT iif(isnull(max(pkid)),0,max(pkid))+1, [@strFirstName], [@strSurname], [@strCity], FROM Users;This application is generally run as a networked application with up to 40 people using the application simultaneously, and combined with design issues already mentioned, this has resulted in serious concurrency issues with several users being assigned the same primary key value. This == BIGNow I need to sort this out (guess what I will be doing this weekend!! Great.). I have thought about maybe using a mutex around the code that calls the Access insert queries; not the neatest of solutions, but it would be the quickest. Ultimately though, I would like to have the database corrected and have proper primary key values in place. But the application is currently running at about 15 different sites, so I need to do some sort of batch update of the database.

View 6 RepliesDB/Reporting :: Updating An Access Table?
Mar 31, 2009This may seem like a simple problem, but I am completely baffled. I am working on a timekeeping application using Visual Basic 2008 Express and Access 2000.
There are three tables being updated by three separate sub routines. Two work fine, one does not.
In trying to resolve the issue I test one field at a time. The test Access query and the code only reference the one field to change and two ID fields. The program runs but the field is not updated. The table has 42 fields to be updated when I get it working.
The Access query is:
--------------------
UPDATE tPPSummary SET W1MonHours = [@W1MonHours]
WHERE EmployeeID=[@EmployeeID] AND PPID=[@PPID];
[Code]....
When I pause the running program at the intRowsAffected it shows 1 record which is correct.
I am really out of options as tho where to go from here. There are no simple spelling errors in the parameters, there are no error messages and the sub runs to the end.

The following code makes a connection to the database, fills a dataset with the data from the database, reads a txt file with user name and passwords, and should update the dataset and then the database. However, I keep getting an Syntax error on the INSERT INTO statement on the datest.Update(dsUser,"User") line.
