How to Export Dataset to .mdb file

Hi Saravana,

I found solution for this, add below code in your solution and modify code accoding to your Dataset. call this function and pass parameters of this

strDirectory = your .MDB Savingpath
dtt=your Dataset

private void Exportmdb(string strDirectory, System.Data.DataSet dtt)
{
try
{

Catalog cat = new Catalog();
UpdateProgress("");
string str = "provider=Microsoft.Jet.OleDb.4.0;Data Source=" + strDirectory;
cat.Create(str);
cat = null;
OleDbConnection sceConnection = new OleDbConnection(@"Provider=Microsoft.Jet.OLEDB.4.0; Data Source=" + strDirectory);
sceConnection.Open();
foreach (System.Data.DataTable dttemp in dtt.Tables)
{
string tableName = dttemp.TableName;

StringBuilder stbSqlGetHeaders = new StringBuilder();
stbSqlGetHeaders.Append("create table " + tableName + " (");
int z = 0;
StringBuilder stbSqlQuery = new StringBuilder();
StringBuilder stbFields = new StringBuilder();
StringBuilder stbParameters = new StringBuilder();


foreach (DataColumn col in dttemp.Columns)
{
string datatyp = col.DataType.Name.ToString().Trim().ToLower();
if (z != 0) stbSqlGetHeaders.Append(", "); ;
String strName = col.ColumnName;
String strType = col.DataType.Name.ToString().Trim().ToLower();
if (strType.Equals("")) throw new ArgumentException("DataType Empty");
if (strType.Equals("int32")) strType = "Number";
if (strType.Equals("int64")) strType = "Number";
if (strType.Equals("int16")) strType = "Number";
if (strType.Equals("float")) strType = "float";
if (strType.Equals("double")) strType = "Double";
if (strType.Equals("decimal")) strType = "Double";
if (strType.Equals("string")) strType = "memo";
if (strType.Equals("boolean")) strType = "Bit";
if (strType.Equals("datetime")) strType = "datetime";
if (strType.Equals("byte[]")) strType = "Image";

stbSqlGetHeaders.Append("[" + strName + "] " + strType);
z++;

stbFields.Append("[" + col.ColumnName + "]");

stbParameters.Append("@" + col.ColumnName.ToLower());

if (col.ColumnName != dttemp.Columns[dttemp.Columns.Count - 1].ColumnName)
{
stbFields.Append(", ");
stbParameters.Append(", ");
}

}
stbSqlGetHeaders.Append(")");
OleDbCommand sceCreateTableCommand;
string strCreateTableQuery = stbSqlGetHeaders.ToString();
sceCreateTableCommand = new OleDbCommand(strCreateTableQuery, sceConnection);
