I'm having a problem with some code which seems to stop my program from working correctly. Below is my (i have only added to code which i think you will only need to see.

I coded a program to access a Microsoft Access 2010 database. The program is written using Microsoft Visual Studio 2010. I get the error message that the database I'm trying to access is in an invalid format. look at the code below to see what I missed. The error is in the datasource statement.

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?
When i select an image randomly from an imagelist on my form and insert it into a picturebox, how can i stop that image from being selected again while the program is open ?
View 1 RepliesThis program is very difficult for me, but I must get threw it or I cannot finish... What I am doing is making a Database of foreign Languages with the spelling of the words and the pronounciation inside the database... The USER enters a paragraph of words into the translator textbox and pushed translate. The program has a DATABANK of words with the phonetic spellings and matches the word, then translates to phonetics. The problem is that new words keep appearing inside the language. So I incorporated a Database of 2 fields

Out of curiosity, is there a way i can make a program stop or pause for a period of time (which i would choose) before continuing the code WITHOUT a timer.I think I've seen this done before, but I'm not positive.Also note that I'm talking about a forms application (not a console app if that would be any different.)

For those of you that have been helping me for the last two days thank you first of all, my program is now at the stage where i need to have a windows application that the user can then select databases from, and then using these databases information will be put into a second application that will then run a program to compute some data and spit it into a .xml file.
Is there a prewritten piece of code for choosing databases? And then a set format for choosing cells in that data base to be exported into another windows application?
I want to create program in vb2008 express with ms access database. Can somebody help me so i can learn how to program using classes hard coded. I have learned vb6 before but it has a big difference on vb2008.
I have a database named "DATABASE" in ms access 2003 and the details are: Table :
EMPLOYEE(EmpNo, EmpName), DEPARTMENT(DeptID, DeptName), CATEGORY(CategoryID, CategoryName), SUPPLIER(SupplierID, SupplierName), ITEM(ItemID, Itemname), ITEMLIST(ItemListID, ItemID, ItemDescription), INVENTORY

All the CAPITALIZED name are Table and all items inside the parenthesis are fieldnames. I don't know where to start on working on this RECORDS. I was able to understand visual basic 6 a bit, and i am trying to apply the coding to VB 2008 but all i get is errors. I am hopeless now and i need help to be able to start my programs. If someone can give me a sample code, i think i would be able to trace the line of code to be able to understand it. I am currently an inventory manager on the small company i was working with and i like to organize my record by using database.

View 8 RepliesI have started a little program which is linked to an access database, and it basically allows the user to input a name and a picture, with the file path stored in a text box and the picturebox getting the picture location from said text box. At the moment I am using the BindingNavigator to go between data. Everything works fine, however, whenever I press previous or next, the picturebox loads up the picture using the file location of the previous datas picture field. How can I tweak this so that when I press next or previous it loads the picture into the picturebox using the file location of the data I am going to, not coming from? [code]

but now that im looking at the data this is prolly only useful for simple data. Im wanting to seperate the data from queries into multiple boxes. Am i better off just manually having a connection to the database and running queries into arrays to sort the data?? The above method looks like im going to be trying to fight the databound stuff. There are two tables and the way the built in query builder is im starting to think its easier to write my own queries in variables or whatever.

I open the code up on my computer at school and it has errors saying ti does nto recognize the MySQL code as it does not have it in its .Net library. So i try to download it into the library but that does not work. So my question is, will programs using any kind of database not work unless the user installs the needed add on, weather it be a .Net library add on or a java add on for MySQL? That cant be right it.

View 1 RepliesI've seen used the datagridview to save the changes.
I don't use a dgv, but rather I connect directly to access and when a text field has text in it, it takes that text and searches, and updates various text boxes with the according information (finds a row, and takes all the data in the columns and adds it into their respective box). There are approximately 5-7 text boxes being used at the same time, and only a few will be changed.
How would I go about updating and saving through the VB program?
