Hi,
how can i set data in a IFieldObject, i place that kind of "textboxes" in a myreport.rpt and i want to set data there as i do in ordinary winforms textboxes.
I want to do this the "same" way i fill a datagridview.
public static void DataGridView_Fill(DataGridView data_grid_view, string store_procedure)
{
SqlConnection sql_conn = new SqlConnection(connection_string);
SqlCommand sql_cmd = new SqlCommand();
sql_cmd.Connection = sql_conn;
sql_cmd.CommandText = store_procedure;
sql_cmd.CommandType = CommandType.StoredProcedure;
sql_conn.Open();
SqlDataAdapter sql_da = new SqlDataAdapter();
sql_da.SelectCommand = sql_cmd;
DataTable dt = new DataTable();
sql_da.Fill(dt);
sql_conn.Close();
data_grid_view.DataSource = dt;
}

I am trying to use the example mentioned as compatible across the platform to generate a MD5 hash. http://msdn.microsoft.com/en-us/library/system.security.cryptography.md5cryptoserviceprovider.aspx#[^]
My other system would generate MD5 hash through PHP function. For some reason, the two does not seem to tally. I have also used a simple Java Code to generate MD5. Java and PHP identically generate the same hash for a given string but this one generates a totally different one.
Any clues?

I've come accross this before but a long time ago - I haven't used MD5 in quite a while.
This is[^] one I had bookmarked, I don't know if I ever tried it - but should hopefuly help.

Thanks for the assistance.
In the URL, one of the example uses 'X' (.toString("X")) instead of 'X2'. This seems to be working for me. Thanks again.

What are you hashing? If you have numeric values in your stream you may find that storing the numeric values in network byte order will cause the function to output correctly.

@Ennis,
DaveyM69 suggested another trick to change the format specifier and that seems to be working. Anyway, later I would also try using your suggestion 'network byte order'

Check the encoding of your input data. Your .Net end may be using unicode strings instead of ascii.

Class A
{
public virtual event CEventHandler myevent;
MenuItem[] menuItms = new MenuItem[]{ new MenuItem("Color", new EventHandler(Color))}
ContextMenu.MenuItems.Add(menuItms);
private void Color(Object sender, EventArgs e)
{
if(myevent!=null)
myevent(sender, e);
}
}
Class B: A
{
public override event CEventHandler myevent;
MenuItem[] menuItms = new MenuItem[]{ new MenuItem("Color", new EventHandler(Play)}
ContextMenu.MenuItems.Add(menuItms);
private void Play(Object sender, EventArgs e)
{
if(myevent!=null)
myevent(sender, e);
}
}

Virtual events are one of those things they (MS) whish they could uninvent! Overriding the event does not create a new event hence your null problem.

you r right but perhaps a sample would be good enough to make newbie happy. However, I found the solution.....Had to declared a method in the baese class and call that method from the derived class and passed the information to the base class

I am reading the contents of excel file and storing contents in database.
I am using two datatables org_dt and grid_dt.
i am having a problem while adding rows to grid_dt datatable, also having problem while inserting date into this table.
here is the source code:-
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Data.Odbc;

string connectionString;// @" Dsn=Excel Files;dbq=C:\Program Files\Common Files\ODBC\Data

OdbcConnection conn = new OdbcConnection();
OdbcCommand cmd = new OdbcCommand();
OdbcDataReader dr;
System.Data.DataTable org_dt = new System.Data.DataTable();
System.Data.DataTable grid_dt = new System.Data.DataTable();
string project_no = "", summary = "";
string[] divpara = new string[3];
string[] yes = new string[4];
public Frm_admin_upload_optn()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
openFileDialog1.ShowDialog();
textBox1.Text = openFileDialog1.FileName;
}
private void Frm_admin_upload_optn_Load(object sender, EventArgs e)
{
}
private void button2_Click(object sender, EventArgs e)
{
try
{
connectionString = @"Dsn=Excel Files;dbq=" + textBox1.Text.Trim()

conn.ConnectionString = connectionString;
cmd.CommandText = "SELECT * FROM [sheet1$]";
cmd.CommandType = System.Data.CommandType.Text;
cmd.Connection = conn;
conn.Open();
dr = cmd.ExecuteReader();
org_dt = new System.Data.DataTable();
if (dr.HasRows)
{
org_dt.Load(dr);
grid_dt.Columns.Add("PROJECT NO");
grid_dt.Columns["PROJECT NO"].DataType = typeof(string);
grid_dt.Columns.Add("TICKET NO");
grid_dt.Columns["TICKET NO"].DataType = typeof(string);
grid_dt.Columns.Add("REPORTED DATE");
grid_dt.Columns["REPORTED DATE"].DataType = typeof(DateTime);
grid_dt.Columns.Add("OLD COMPUTER NAME");
grid_dt.Columns["OLD COMPUTER NAME"].DataType = typeof(string);
grid_dt.Columns.Add("NEW COMPUTER NAME");
grid_dt.Columns["NEW COMPUTER NAME"].DataType = typeof(string);
DataRow grid_dt_row = grid_dt.NewRow();
for (int j = 0;j<4;j++ )

int i = 0;
foreach (DataRow drow in org_dt.Rows)

project_no = "Project #-";
else project_no = "Project Number #-";
divpara[0] = project_no;
divpara[1] = "New PC Name :";
divpara[2] = "Old PC Name :";
yes = summary.Split(divpara, System.StringSplitOptions.None);
//grid_dt.Rows.Add(grid_dt_row);

MessageBox.Show(e1.Message);
}
finally

The error: "This row belongs to another table" is legitimate because the row contains a reference to the table that initiated it. (row.Table) If you are wanting to copy the row's data into another table with the same schema, try this syntax:
secondTable.Rows.Add(firstTableRow.ItemArray());
As to the date error, it would help if you could post the error text.
Cheers!

I created a combobox that binds to a datasource. If the combobox only contains one item, I programatically select the one item and want to trigger SelectionChangeCommitted event just as though the user had selected it. How can I call this event manually?
|
|
|
|
|
The OnSelectionChangeCommitted that raises the event is protected virtual so it is only accesible in derived classes. Therefore, I think the only way to call that method to raise the event is by your own class the derives from ComboBox:
public class MyComboBox : ComboBox
{
public void RaiseSelectionChangeCommitted()
{
base.OnSelectionChangeCommitted(EventArgs.Empty);
}
}
You can now use the RaiseSelectionChangeCommitted method to call the base method and raise the event. This is probably not advisable and there is probably a better way but it's all I can think of - and it works!

Is List<object> fundametally the same as ArrayList or should I prefer one over the other?

No, but perhaps I should care what some loser that doesn't even know what generics is and can't be bothered to read documentation to learn about it, thinks about my post? Nah, not so much.

The first, is a generic list specifically of type object. the second is a non generic list, written to hold object types.
If you use "object" in the generic one, then yes they are pretty similar. but why are you storing a list of objects? You should create you list with the specific type you want to store
i.e. List<String>
Doing this is wayyyy better than using an ArrayList to hold strings because the generic form enforces type safety, you don't have to cast, and you don't have to write a specific class. (And in the case of value types, prevents boxing)
You can do some reading on generics here:

I cannot tell the type of the data being collected at compile time. It could change based on the situation.

if you're working with pure objects only then I don't think there's a great deal of difference. If not, the generic list is obviuosly far more flexible and much quicker as you can use any type without boxing/unboxing.
As there is no advantage to the ArrayList I never use them. This page[^] (is probably quite old) has a comparison of the two.
