sqlce database to the picturebox?

get works L



This is the code I work whit:

Dim cn As System.Data.SqlServerCe.SqlCeConnection = New
System.Data.SqlServerCe.SqlCeConnection("Data Source=SD Card\My
Documents\Scubase.sdf")

Dim cmd As New System.Data.SqlServerCe.SqlCeCommand 'Option

Dim da As System.Data.SqlServerCe.SqlCeDataAdapter 'Option

Dim dt As System.Data.DataTable = New
System.Data.DataTable("PicturesOrganism") 'Option

cn.Open()

cmd.CommandText = "SELECT * FROM PicturesOrganism"

cmd.Connection = cn

da = New System.Data.SqlServerCe.SqlCeDataAdapter(cmd)

da.Fill(dt)

Label1.DataBindings.Add(New Binding("Text", dt, "PictureName"))

My code:



Dim cn As System.Data.SqlServerCe.SqlCeConnection = New
System.Data.SqlServerCe.SqlCeConnection("Data Source=SD Card\My
Documents\Scubase.sdf")

Dim cmd As New System.Data.SqlServerCe.SqlCeCommand 'Option

Dim da As System.Data.SqlServerCe.SqlCeDataAdapter 'Option

Dim dt As System.Data.DataTable = New
System.Data.DataTable("PicturesOrganism") 'Option

cn.Open()

cmd.CommandText = "SELECT * FROM PicturesOrganism"

cmd.Connection = cn

da = New System.Data.SqlServerCe.SqlCeDataAdapter(cmd)

da.Fill(dt)

Label1.DataBindings.Add(New Binding("Text", dt, "PictureName"))
 
I must admit I struggled to achieve this under CF mainly because of
limitations in place.

So instead I changed my SQL CE image data type to ntext and saved the byte
array of the image as a base64 string. Of course if you are using images of
great size then it is not recommended to store these in SQL CE as you will
soon run out of memory when trying to execute ADO.NET instructions.

Alternatively try posting a question here:
