FileSystemWatcher and syncing database with changes

I’m creating an application (just started) with a front end (GUI) and backend (database). The database will be populated with file related data populated from the FileSystemWatcher. I want to discuss the database design and how it relates to the files and their paths and how information is obtained via FileSystemWatcher. Since folders usually contain multiple files, I thought it would be a good idea to have a file table and a folder table. Since file names (without path) may not be unique, I thought using an integer as a primary key would work well especially if the file ge

Dynamic Instantiation With Generic Parameters

Kinda stumped on this one...

I'm going to build a list of objects of this type at run time, from a table in a database that corresponds to the properties of GenClass. I've got a code in the database that identifies what VType should be for each instance (for example, 1 would be "String", 2 would be "Integer", and so on). So far, so good.

What is best way to read binary file into string?

Hi all, I am now building a routine that reads a small (no larger than 100 bytes) binary file and saves the contents in a string. The file can contain characters anywhere in the 0 - 255 ASCII range.

Where is "imports Win32"?

Dumb question I know, but after 2 hours googling I give up. What is the easiest/recommended way to access the Win32 API from VB Studio Express? I assumed it would be a simple matter of Imports Win32, or something similar and the whole API would be exposed. Surely I don't have to Declare every API function I call individually? I just want to do things like FindWindow, GetForegroundWindow and SendMessage. There are also a gazillion constants like WM_CHAR et al, that I would have thought were predefined somewhere.

Design question

So I'm developing a new application for Windows Mobile (WindowsPhone) that will use a REST API I'm developing to interact with a backend MySQL server. While I need to make access secure (it's a medical app), I don't want the user to constantly have to hit the user table of the database every time they want to do an API call as that table could have thousands of rows and could slow down access a bit. So my thought is to use sessionID's of sorts. When the user does the first call to the API (which should be a login call since they need to login to the app), the mobile app will a

Dynamically adding menu items and their OnClick events

How do I add items to a menu while simultanesously adding an OnClick event for each.

Problem calling unmanaged DLL from VB.NET

I've been bashing my head up against a brick wall for 4 days, and I've reached the limit of my frustration and knowledge. I'd appreciate some ideas on what I'm doing wrong. I have a simple Visual Basic Express 2008 program. It calls a DLL (supplied by others). Calls to the DLL in small (trivial) programs work fine. When the program grows in size I get a "vshost.exe has stopped working" message. It happens when I call any dll function that tries to return a string. I have googled and tried everything. The full program is a few thousand lines, much of it auto coded because of

Hi Group I think that what I would like to do is not possible. I would like to create a class with four possible sub classes which must inherit data from the master class. In the first class I would like to do some work which would then instantiate one of the four sub classes without calling New in the first class. The sub classes each has the potential for holding large amounts of data, there for I don't want to instantiate them if not necessary. When I do call the chosen sub class from the first class, I would like it to inherit some of the data that the first classes created.
