Please close your previous threads by marking helpful posts as answer before you start a new one.
The type of the image columns should be BLOB. And make sure that you are looking at the inkCanvas_DB.db in the output folder of your .exe ([your_project_foder]/bin/Debug or [your_project_foder]/bin/Debug) because it is this database that the data gets written
to unless you specify an absolute path in the connection string:
string stConn = @"Data Source=C:\Your_Project_Folder\inkCanvas_DB.db;Version=3";
