OLEObject Bitmap Image Pulled To Imagebox Via OLEDB Connection?
Jun 9, 2011
i am trying to pull a bitmap image stored in a table location with an OLEObject type to my picture box on the form. The code i am using is as following:
img_ProductPicture.Image = DS.Tables("LocationInfo").Rows(0).Item(5)
The error i am receiving is an InvalidCastException:Unable to cast object of type 'System.Byte[]' to type 'System.Drawing.Image'
Am i missing something when pulling the image which will display it?

im trying to write to an sql database. im inserting an image, as well as some other information. I am using the following code which works fine, as long as i do not add an extra column/variable "LOCATION" in to the mix and leave "
'Cmd.Parameters.Add("@LOCATION", OleDb.OleDbType., 3).Value = "testing"
commented out. *this is undesireable as im trying to add extra criteria to be saved like LOCATION.
Try
Dim st As New FileStream("\serverfolder1storage" & "pdftemplate.jpg", FileMode.Open, FileAccess.Read)
Dim mbr As BinaryReader = New BinaryReader(st)
Dim buffer(st.Length) As Byte
[code]....
i am trying to store the location e.g "c:file1.jpg" in the sql db. Can anyone reccomend a solution to this using OLEDB? ideally i need to add approx 4 more variables. e,g
firstname
surname
dob
location

i want to ask what is the difference between oledb connection and odbc connection. I have a case, my office used ncomputing then i have to developed an application using sqlserver 2000 and vb.net 2005, i used oledb connection. When i try to implement it in ncomputing, why user must has admin access level and dbo level in sql server, it seems trouble when all users are admin. But there's a rumor that when using odbc connection, we dont need to give admin access level for users.es.

A While back I developed a application that connected to Excel using DB connection. It worked fine since the application was designed for usage on one particular PC with Excel 2003. I especially liked the solution since the data retrieval was much faster compared to what I would get if I connected to Excel using Interop libraries.
However, recently when I tried to implement the same solution onto another app that would run on various PC that could use different versions of MS Office I ran into multiple problems. First of all, I can't use the same connection string on various versions. Also, the whole x64 vs x86 thing is adding to the problem.
I wonder if there is a way to check the version and use the apropriate connection string for every version?

I have a problem with Oledb connection when I am trying to open an Excel spreadsheet:
[code]...
This piece of code works well on one computer, but on another the IMEX=1 doesn't seem to work, and the Jet seems to read the first few rows of the Excel spreadsheet that are numeric and decides that the whole spreadsheet is numeric, so it ignores some String values later in the sheet.
