I'm trying to use a loading overlay on top of a Windows form that adds a 50% opaque layer on top of a windows form with a loading GIF, while it does what it needs to do in a background thread. The overlay is a windows form that I'm drawing in the onPaint event.
The loading overlay works fine on multiple different form loads, but fails to work properly when summoned to ensure patience during a 30 second upload process (That Prints a Word Document to PDF, then uploads that PDF to a SQL Server). This upload collects some data from the form, puts it into an Object, then operates entirely on a background thread. The loading overlay will appear, show the first frame loading GIF, then just freeze. The onPaint is getting fired and the image frame is being updated, but it isn't visible
Constructor sets the form to be UserPainted:
Sub New()
InitializeComponent()
SetStyle(ControlStyles.UserPaint Or ControlStyles.Opaque, True)
End Sub

Ive been programming in VB6 for years, i figured its time for an upgrade. Here's what im doing, and what the problem is:
Im loading a bunch of pictures on top of one image. They are all PNG files, and some of the images have transparent edges, and some semi-transparency within the image itself.
So basically, i need to be able to load these images on top of the other images, and still maintain the transparency.
Is this possible in VB08? This is one of the main reasons i moved to 08 from vb6, more things possible including multithreading.
What is the best way to do? Load the pictures to the program and using many different forms? or just make a folder to the pictures and load them by using the [code]....

I'm writing a program in VB.Net and loading the info into a SQL database. Debugging it works fine on my machine that I am programming it on, it connects to the database and runs through all the info perfectly. However trying to get it to run on another machine it will not connect to the database. I realize the reason for this is the connection string, it's looking specifically at the file directory for the database. How do I change this so that it will function on any machine. The program is only intended to run on one machine at a time and not over the internet.
