I am currently coding a tabbed web browser. I am adding a bookmarks function, but this stupid error is holding me back from compiling. I believe the code is flawless, but yet it says that a period is an invalid chracter [Code] The period in the SelectedTab.Controls is the one causing the problems, and I have no idea why.

Dim data As Byte() = DirectCast(sdr.Item("Image"), Byte())
Dim ms As New System.IO.MemoryStream(CType(sdr.Item("Image"), Byte()))
PictureBox2.Image = Image.FromStream(ms)
After reading many forums and trying the different examples, when I try and load my image from the database I get the "Parameter is not Valid" error.Im using VB 2010, SQL Server 2008 R2, and the data type is Image. I do not have access to the source code that is used to save the picture to the database, just access to tthe data in the db.The code I have included is the code I use to retrieve images from my db which stores the pictures as Image.

I am trying to pull data from an SQL Database and put it into some variables to use. The problem I am having is I have a date field called DateSubtmitted that is originally set to Null in the database. When I try to pull it into a vb.net variable called SubmittedDate As Date, it is giving me the following error:
Conversion from type 'DBNull' to type 'Date' is not valid.
I thought that VB.Net data types could all hold the null value, but I guess not. I know this must be a beginner mistake, but how can I make the null value work. My code is below, the line that gives me the error is[code]...

We have data feed, a file with index values and dates (like the S&P 500, for instance). The dates are represented as YYYYMMDD. The Date.Parse() method doesn't understand this format, of course.I wrote a simple static method on a class to parse this, not a big deal, but it irritates the engineer in me that I can't figure out how to get the IFormatProvider functionality to work. All the examples deal with the FORMATTING step, not the PARSING step.So basically, I want to be able to say:
Dim d as DateTime = Date.Parse("20110522", New CustomFormatter())
and get the correct date value out of the Parse method.
Having implemented the IFormatProvider method on CustomFormatter, the GetFormat() method gets called with a System.Type of DateTimeFormatInfo, but I honestly have no idea what to do from there since all the example deal with formatting, not parsing. It doesn't matter if I return an object (self) or null I simply get "String was not recognized as a valid DateTime."
