I am working on a program that is using Access as its datasource. I would like to be able to have the user "approve" a bid and then the database copy that row into the Approved Bids table from the Submit for Approval Table and then delete the entry from the Submit Table.

I was trying to upgrade my project from VB6 to VB2008
Upgrade Error Line

A program that I'm designing for a local jewelry shop to print receipts and what not, there are multiple cashiers. I have written a database in Access with the Cashier ID, First Name, Last Name, PasswordI have added this to my dataset, it shows up as CashierDataSet1. What I need to do is verify the Cashier ID, and the Password match TextBox1, and 2. All the tutorials I have found are for accessing that database on the local hard drive, which would be fine if I could get rid of my UnauthorizedAccessException error. Any ideas or well known tutorials for using a database in a dataset without pulling the text boxes onto the form and creating that navigator ?
View 3 RepliesI have a bound datagridview which populates from the database using parameters. I've added a combobox column through the datagridview properties. How do I access this combobox column datasource?
View 9 RepliesI have a Repeater Control which I bind to a list of Products
Repeater.DataSource = ProductRepository.GetProducts();
Later (in another module), I need to retrieve the products from the Repeater, but it seems not to work with Repeater.Item.DataItem (which is then null).
My question is, is there any reference to the products in the Repeater-Items? Or do I have to set it myself via id field etc. What would be the easiest way to get the "underlying" product objects?
I have an arraylist:
[Code]...
I know how to use <%#Container.DataItem%> to dump everything but I need to get at the items in the array individually, not have them all ditched out to the page in one go. For example, item 1 contains a link, item 2 contains an image path, item 3 contains a description. I need to have them kick out in the correct order to build the link and icon correctly.
I have made several changes to the columns in an Access db, such as additional columns, column type changes, etc. how do I now incorporate those changes into my datasource? Do I need to delete the datasource and create it from scratch?
View 1 RepliesI have a datagridview that is populated using an oledbconnection:

[Code]...
The problem I now face is that the 'index' value of the combobox item for each row is in the field specFieldType which is populated into the datagrid.I need to be able to set the value of the ComboBox for each row when the form is opened, and also be able to save the index value of each row selection if any changes are made/saved.
I am trying to find a way to use a month calendar control as an object data source, such that when end user selects a given date, or a date range (1 week max), it will supply the date range criteria for an access query, and the results will wind up displaying in a data grid view below the month calendar. I am having a really hard time..
how to write the date criteria into the access query for something like this

I am using VB 2008 to develop apps working with Access. With this IDE I can compile my apps as x86 . Then runs fine under 64 bits Windows 7 and Vista Systems.
First question:but if I run this app under XP 64 bits, will run fine too?
second question:the apps developed with VB 2003 (these work with access too ..."jet oledb"). How I can compile as x86? I have not seen this option like VB2008.

I am converting old VB6 code to VB.NET with ADO.NET (OleDB). This is my query that will create a blank table when ran in VB.NET, but then works when ran directly in Access. This code presumably also works in VB6, as I am using the same SQL:
SELECT qryAsOf.name, qryAsOf.type, 0 as opt, 0 as swap
INTO qryCon
FROM qryAsOf
LEFT JOIN qryLinked on qryAsOf.c = qryLinked.lc
I feel like this has something to do with the left join and select into being together, but like I said it is only VB that has an issue with it, Access handles it perfectly.Without the INTO line, this query returns all 600+ rows.
This DOES NOT WORK:
cm.CommandText = "CREATE TABLE qryCon (etc...)"
cm.ExecuteNonQuery()
cm.CommandText = "INSERT INTO qryCon SELECT ..." '(rest of query above without INTO line)
cm.ExecuteNonQuery
This DOES WORK:
cm.CommandText = "CREATE PROC qryCon AS SELECT ..." '(same select as above without INTO, again)
cm.ExecuteNonQuery
The CREATE PROC that does work is fine, except I need to insert data into it later, so I get errors about how I need an updatable table. I really want the end qryCon to be a table, but I can't seem to get that to work :(
*However, when I do something like this (using the stored proc (renamed) above which, if viewed in Access, is full of data)
cm.CommandText = "SELECT * FROM storedProc"
dr = cm.ExecuteReader
[code]....
This DOES NOT WORK! By the way, I removed the concatenation in the query for readability. It is correct in the actual project.
this is the code

I am running Windows 7 pro and using Visual Basic 2010 express.I have written a small program to switch on a USB relay which is controled by a serial port.I have debuged the program and it appears to work correctly. I have published the program and if I start it from thr run menu / desktop shortcut / or through explorer it works as expected.
However I have tried to run it by the Task Scheduler and then it fails to run as expected. I have a small section of code that checks to see if the serial port is present if not I have used messagebox.show to ask for the relay to be pluged in. In every case other than when running through the Task Scheduler the messagebox works with the Task schedulerit doesn't show the messagebox and the program hangs I have included the code I have used.

I have a program where a lot of the required information for it is stored in text files. I simply read this information into large arrays. However, I don't think it's necessary to load all the information each time. Rather, it would be more efficient if I could simply search through a list of items to find the one I need and then use the data from it, or to find a similar name and use it elsewhere.
Would I be right in using a database? And is database programming done in SQL? I have a book on it telling me to use the SQL Server (IIRC), so I shouldn't be doing it in the VB.NET Express GUI?
Here's an example of what I would do:
Hex = 03 00 => dex number 003
Search in file Pokemon Dex Numbers
003 returns Bulbasaur
Check Bulbasaur base stats in the base stats file
etc
So basically I'm reusing a lot of information. I think a database would be best and it would all be internal right? I'm getting complaints about access denied to a text file (since it's stored in the program directory in the program files).
So to cap up the few questions I have:
-Databases are done in SQL and not inside the GUI?
-Databases would load internally?
-I could search a database without having to load it into like an array or something?
