I want to create a lookup program for library books using VB6 or VB.net.
I have created a Form1.VB with two listboxes :- Listbox1 Listbox2.
Im using an Access Database with a Library Category Table
Field1: Category
Library Title Table
Field1: Category
Field2: Title
Field3: Author
Field4: Publisher
Using the Data Adapter ConfigurationWizard Ive created
OleDBDataAdapter1
OleDBConnection1
And from the Library Category table Ive created Dataset1 attached to Listbox1
OleDBDataAdapter2
And from the Library Title table Ive created Dataset2 attached to Listbox2.
Both Datasets fill using the Preview Data function. I then load Variable CategoryString with Listbox1.text,
and I would like to know how to search Dataset2 and retrieve all titles linked to that category and display Title, Author, Publisher in listbox2.
I am a self taught "developer".I use the term loosely because I only know enough to make myself dangerous. I have no theory background, and I only pick up things to get this little tool to work or make that control do what I want.
That said, I am looking for some reading material that explains some of the theory behind application development especially from a business standpoint. Really I need to understand what all of these terms that float around really talk about. Business Logic Layer, UI abstraction level and all that. Anyone got a reading list that they feel helped them understand this stuff? I know how to code stuff up so that it works. It is not pretty mostly because I don't know the elegant way of doing it, and it is not planned out very well (I also don't know how to plan an application).

I probably confused memory usage issues with the UI sharing same thread as the processing (as pointed out by MusiGenesis below). However regarding the Memory usage. I am still not able to find VB.net specific syntax, although people have pointed out some great .Net and C# information below (and if I were more versed in those technologies, one could adapt to make work with VB.net).The general concepts are working fine, however I am having issues where the Mem Usage on Task Manager keeps growing as the program is used to load more and more files.On Startup, before doing anything, the VB application has 27,000 K.Once the file is parsed and even after I dispose of the File handle as well as the the data increases a lot. I strip out everything in the code and it still seems that memory in Mem Usage remains captured. There is no rhyme or reason as to why the Mem Usage is growing (i.e. sometimes it can grow by 20 mb when reading a 7mb file, however other times it does not increase at all, when reading a 3mb file). Sometimes, it appers to release some memory when the parsing is complete and other times it just holds.I have looked at .Net Memory Profiler and have not really been able to make heads or tails from that.I have read a lot on internet regarding Memory Management on .Net in General about Dispose and "Nothing" and DataSets, etc, however have not really found anything regarding VB.Net specifically.My General Question is: Are there any good tutorials/books/blogs/etc that show a more in depth tutorial on managing memory in a VB.Net application (i.e. how/when to dispose/close, etc), or does anyone have some specific tips from there experience.
