in yur code you assign a value for the txt... from the dataset
if you want the to do the same from the datagrid:
txtUsrName_pca.Text = dtg.Rows[i].Cells["CreditCardOwner"].Value.ToString();

hi assaf,
got an error when compiling.
'System.ArgumentException'
in this line
adp = new SqlDataAdapter(cmd);
ds = new DataSet();
dtg.DataSource = ds;
dtg.DataMember = "M_CUSTOMER"; --> got an error here!
adp.Fill(ds);

This Exception here mean that the table "M_CUSTOMER" doesn't belong to the dataset "ds"
So verify when you run the program that the dataset contain this table and check his Name
hope that this help you ...

I have two different ways:
private Dictionary<<string, double>> innerTable;
private Dictionary<<string, Dictionary<<string, double>>>> outterTable;
public DataAccessLayer()
{
innerTable = new Dictionary<<string,double>>();
outterTable = new Dictionary<<string, Dictionary<<string, double>>>>();
innerTable.Add( "stringKey", 12312.012 );
outterTable.Add( "anotherStringKey", innerTable );
}
public class UsingMyNewCollections
{
public UsingMyNewCollections()
{
InnerDictionary inner = new InnerDictionary();
inner.Add( "StringKey", 1213.0123D );
OutterDictionary outter = new OutterDictionary();
batchTable.Add( "SomeKeyString", outter );
}
}
public class OutterDictionary : IDictionary<<string, InnerDictionary>>
{
private Dictionary<<string, InnerDictionary>> m_outterDictionary;
public OutterDictionary()
{
m_outterDictionary = new Dictionary<<string, InnerDictionary>>();
}
public void Add( string key, InnerDictionary value )
{
m_outterDictionary.Add( key, value );
}
#region IDictionary<<string,MyTable>> Members
#endregion
#region ICollection<<KeyValuePair<<string,MyTable>>>> Members
#endregion
#region IEnumerable<<KeyValuePair<<string,MyTable>>>> Members

}
public class InnerDictionary : IDictionary<<string, double>>
{
private Dictionary<<string, double>> m_innerDictionary;
public InnerDictionary()
{
m_innerDictionary = new Dictionary<<string, double>>();
}
public void Add( string key, double value )
{
m_innerDictionary.Add( key, value );
}

I think u have accidently landed up in the wrong place, you may try out the Hardware section for your query, u are most likely to find the right solution there. This is C# zone.

Are you asking how to detect all enum types without having to check for each specific type individually?
Enums derive from System.Enum - perhaps you could check that instead rather than have to list all enum types.
|

|

Solved
else if (propertyType.IsEnum)
{
result = Enum.Parse(propertyType, value);
}
actually this was my mistake as I was experimenting with
"System.Windows.Forms.Cursor" which is not enum
Thanks and Regards

Yes, if u want to show the latest data then u should use datatable instead dataset
For Example :
<br />
string conect = ConfigurationManager.ConnectionStrings["CON"].ToString();<br />
SqlConnection conn = new SqlConnection(conect);<br />
SqlDataAdapter da = new SqlDataAdapter ("Select * From MyTable",conn);<br />
DataTable dt = new DataTable();<br />
da.Fill(dt);<br />
Hope this can help solve u'r problems

If the bit array doesn't fit and you only need the on/off representation, you can use some long ints and iterate over them. I've done that for some forms where the user had dozens of checked/unchecked options to select.
