Steps
* Start a new project/create dataset and its schema
-New Project
-Go to Form1.cs code
-Imports System.data/system.io
-Create the function "Createdata" to create the dataset:
DataSet Createdata ()
{
DataSet data = new DataSet ();
Data. Tables.add ("Images");
Data. Tables[0]. Columns.Add ("Country", System.Type.GetType ("System.String"));
Data. Tables[0]. Columns.Add ("img", System.Type.GetType ("system.byte[]"));
Data. WriteXmlSchema (Directory.GetCurrentDirectory () + "dynamicimage.xsd");
}
-Create the function "CreateReport" to invoke Createdata to create a dataset pattern:
void CreateReport ()
{
Createdata ();
}
-Call CreateReport in the constructor
Public Form1 ()
{
//
Required for Windows Form Designer support
//
InitializeComponent ();
//
Todo:add any constructor the code after InitializeComponent call
