Why would the reader be closed at this point if I am using different DataReaders in the two loops?

I am using VB2005. I am trying to write to an Access database seperate from the data's origin. AKA: I need to run a query getting data from one Access table and write it to a table in another Access database.
Overview: I need to get data from one Access table and two Excel worksheets. I need to write the data to an Access database so I can run a query combining the three into one table. I will then use the table to create reports.
I have googled, checked multiple sites, and checked MSDN. The only thing I have been able to find is populating a datatable and writing changes back to the database. This was SO easy in VB6.
Is it possible to write to an access database that is an MDE, from a .net application?

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?

View 1 RepliesDisclaimer: I didn't place this in the Database forum because since I'm so new to VB I might not even know of some kind of ingrained function for the saving of data. I have NEVER used standalone VB (I have 2010 Express now) -- I've always used VB 6 in MS Excel for the storage of data, so I really DON'T KNOW what is possible with VB6. (I also don't want to learn ALL of VB just to see what direction I need to go in, I'd rather get a direction -- even if vague -- and learn from there)
Goal: I want to write a standalone application for the creation of, storing of, manipulation of, etc records in Visual Basic 2010.Specifically what I want to do: IN VB, type in a bunch of client information in a variety of fancy windows, and when I'm done, have that client record saved in some kind of database.
Problem: I've tried Googling a ton of things about reading and writing from files (txt seems easiest for me at this instant) and I also see APPENDING to the end of a file. I don't see how a record in the file can be UPDATED. I see saving, I see loading, but I don't see (for example) the identification that I'm trying to save another record for Client 1234 so that it saves over the old client's record with the updated information.
1) Is this possible?
2) What database format would be preferable? (Right now I'm aware of txt, xls, csv, or access as possible options) I'm sure there are strengths and weaknesses to each but if there is general watered down version that would be awesome (I'm not trying to suck away anyone's life force)
3) Sample code, if possible, for whatever record solution you recommend using?(And I know that Access is generally pretty darn awesome, but the final project that I'm hoping to build to is likely to surpass the 'reasonable size limit' of Access that I've been told about)

I have recently decided to give .net another chance, but i have a few questions about it before i get really into it. RE: Files, I use random access files to store data as opposed to databases (namely i don't see the need for a database for storing so little information(records <200 max) knowing that it is an older system and less "cool" i don't care...) Will vs2010 express read, write to random access files? Would it be done kind of like vb6 (which is my current vb version)? I will be needing to print the text of rich text boxes, is vs2010 express capable of doing this?

View 1 RepliesI'm new to Visual Basic. I came across a random number generator tutorial. Got it working fine and then I thought, Is there a way to get it to access a database Here's the thing
1. Generate the random number.
2. looks at the database and finds the corresponding id number.
3. Takes the field for that number and enters it into a text field in the program.
So for example the number generated is 32. Then the program looks at the database and looks for id number 32. then takes the text in line 32 and enters it into a textbox in the program.Now I have my database and the program. But just can't seam to figure out how to get the two connected like I want. I have looked and searched but have found nothing like it I am using Visual Basic 2010 and Access 2007.
I've tested an application (one that I'm developing) that utilizes MS Access database (.accdb) on a backup machine. And I consistently get an unhandled exception error saying 'The Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine. I suppose I get this error because the backup machine doesn't have a driver or whatever to read the Access database file. Reading
this topic titled "How to deploy VB 2010 application as a standalone without MS Access", I understand that I can just specify a prerequisite for this component (driver or whatever...) in the project designer window in reference to this page. I wonder if there is a simpler way of delivering the database component to users? Or should I abandon the Access database and use a different one for easier accessibility?
update access database from vb 2010?
[Code]...
I just started learning VB 2010 through a book. I'm learning vb to design a program which can manage customers of a small company as a homework. It'll store data (Company Name, Phone N. and Adress) at an Access Database. (I'm using Access 2007)
I have a little background with programming but none with databases. According to the book there is no way I can delete, add or update a data from an Access Database without installing SQL Server or Express. But this program should work at a computer which may or may not have SQL server or MS Access (Any computer with Windows OS).
After a little digging only thing I could find was Walkthrough: Saving Data to a Database (Multiple Tables) from MSDN and did every step and at the end, I can delete or add rows and change values of the cells but cannot save them (when I click save, close the program and re-open it, changes are gone).
I don't get that how can I view all the data from database without SQL server but can't save changes to the database file without SQL Server.
Is there a way to do this without SQL Server? If so, can you give the right code for the MSDN Walkthrough's Save button? Or point me to a page where can i learn the right code?
