I have a C# Windows form with a button on it. When the button click event occurs I open a new mail message and supply the mail reciepients and subject. When the user clicks the send button I want to retrieve the mail body for my app.
Is there a way to do this using the application.itemsend event? If so is there any sample code out there showing this.
Thanks!

Hi,
I'm new to Crystal Reports and this is the first report I have written. Heres the problem: I've generated a report viewer that automatically logs in to the SQL server to pull the data. This part works fine and shows the report. I have also created two date pickers for the user to select a date range and refresh the report. When the user clicks the generate button, a Crystal Database login window prompt opens. All the information is already filled in except the password.
How can I make it so this refreshed report also automatically logs in.

Hi,
i would like to export my db (*.mdf) and i have choosen the simplest (i think) way. Just copy the file. The problem is, that i already use this file, so i can't open it. I don't open it at first place, sqlservr.exe does and so i have no control about it.
I searched these forums, but i have found only this
FileStream fs = new FileStream(getDbPath(), FileMode.Open, FileAccess.Read, FileShare.Read))
And in my case it doesn't work.

If you copy the database files that is in use, you don't know if they are complete. The database driver may be in the middle of changing something in the files, so in that case your copy would be corrupted.
If you close all connections to the database, the driver should release the files. The problem with that is that there is a connection pool in .NET that may keep connections, so you would either have to quit your application or manipulate the connection pool.
If you detach the database, it's safe to copy the files.
Despite everything, the person most likely to be fooling you next is yourself.

Hi,
thanks so much for your answer. I googled for detaching the db. Unfortunately sp_detach_db says, that the db is currently in use.
My usage:
SqlConnection conn = daAuthors.Connection;
if (daAuthors != null)
{
daAuthors.Connection.Close();
daAuthors.Dispose();
daAuthors = null;
}
SqlCommand cmd = new SqlCommand(string.Format("sp_detach_db @dbname='{0}'", conn.Database), conn);
cmd.ExecuteNonQuery();
Then i read about ALTER DATABASE DatabaseName SET SINGLE_USER; to obtain exclusive access to db. But i don't know the database name, the "sysname". I have created the db in VS. For sp_detach_db it is path to *.mdf. When i run sp_helpdb, it shows me all db names, but they are just paths to dbs.

Hi;
I'm a C#.net newbee trying to convert from VB.net. Don't have the big picture yet I am sure.
I am trying to trap the mouse_move event in a panel (container) for the form the code (that works) looks something like this.
InitializeComponent();
this.MouseMove += new MouseEventHandler(this.Form1_MouseMove);
}
//--------------------- Mouse Move ------------------------------
//
private void Form1_MouseMove(object sender, MouseEventArgs e)
{
......
}
If I try to do the same thing in a container it does not work.
Can anyone point me in the right direction.....
Thanks In Advance

You want to trap mouse move over a panel control, however the event which you have added is for mouse move event of Form and not of panel control.
Therefore add event handler for panel control, such as –
-----------------------------
private void Form1_Load(object sender, EventArgs e)
{
this.panel1.MouseMove += new MouseEventHandler(panel1_MouseMove);
}
void panel1_MouseMove(object sender, MouseEventArgs e)
{
//Mouse move event of panel
}

thx dave;
the code I supplied was the code that works for the form mouse move event. The code that I am trying to get working is...
private void Form1_Load(object sender, EventArgs e)
{
this.MouseMove += new MouseEventHandler(this.panel1_MouseMove);
}
//--------------------- Mouse Move ------------------------------
private void panel1_MouseMove(object sender, MouseEventArgs e)
{
Point mousePoint = PointToClient(MousePosition);
string msg = string.Format("X:{0}, Y:{1}",
mousePoint.X,
mousePoint.Y);
lblMousePosition.Text = msg;
}
thx

I think you are still not getting the point.
If this is the code which you have used –
private void Form1_Load(object sender, EventArgs e)
{
this.MouseMove += new MouseEventHandler(this.panel1_MouseMove);
}
//--------------------- Mouse Move ------------------------------
private void panel1_MouseMove(object sender, MouseEventArgs e)
{
Point mousePoint = PointToClient(MousePosition);
string msg = string.Format("X:{0}, Y:{1}",
mousePoint.X,
mousePoint.Y);
lblMousePosition.Text = msg;
}
Notice that you are using line –
this.MouseMove += new MouseEventHandler(this.panel1_MouseMove);
In the above line ‘this’ represents form, and not a panel. So still you are not getting a handler for panel control.
Replace the above mentioned line with –
panel1.MouseMove += new MouseEventHandler(panel1_MouseMove);
Notice that I am using ‘panel1.MouseMove’ and not ‘this.MouseMove’. Here panel1 is name of my panel control, if you have used a different name, you should replace it with the name of your panel control.

Thanks again Dave;
I think that I have found the problem this event does not fire. Not sure why but the Form Load nevers fires therefore mouse move is not working
...
private void Form1_Load(object sender, EventArgs e)
but it does not...
THX

So in order to get the Form Load event to work I added this to the Designer of the form
this.Load += new System.EventHandler(this.Form1_Load);
do I need to do this or should VS add this for me when I add the event??
Sorry for these "bone-head" questions but this is the kind-of stuff VB would have added automatically and I'm not sure what has to be added when.

Can I restrict a template parameter to primitive (or unmanaged) types only? Is it possible to enforce this condition so that I can take a pointer to it?
class Example<t> where T : struct {
T* p;
}</t>
I get an error because T is a managed type. I understand this, but is there a way to tell the compiler that it's a native type (e.g. int or double)?

DataTable dt = new DataTable("SomeTable");
string[] tokens;
dt.Columns.Add("ID",typeof(int));
dt.Columns.Add("Name",typeof(string));
StreamReader sr = new StreamReader("C:\\SomeFile.csv");
while (!sr.EndOfStream)
{
tokens = sr.ReadLine().Split(',');
if (tokens.Length == 2)
dt.Rows.Add(tokens);
string strExpression = "ID = 1";
DataRow[] dr = dt.Select(strExpression);
MessageBox.Show(dr[0].ToString());
Can you tell me how would you build and use a select expression and use it in DataTable.Select()
Please, dont link me to some website, but give me your experience or at least try it and let me know how it works.
Many thanks guys!

i've tried your code but no error found
here my code
private DataTable CreateDataTable()
{
DataTable result = new DataTable();
result.Columns.AddRange(new DataColumn[]{new DataColumn("ID", typeof(int)), new DataColumn("NAME")});
return result;
}
public List<string[]> CreateList()
{
List<string[]> result = new List<string[]>();
for (int i = 0; i < 100; i++)
{
string[] data = new string[] { string.Format("{0}", i + 1), string.Format("data_{0}", i + 1) };
result.Add(data);
}
return result;
}
private void button1_Click(object sender, EventArgs e)
{
DataTable dtb = CreateDataTable();
List<string[]> result = CreateList();
for (int i = 0; i < result.Count; i++)
{
dtb.Rows.Add(result[i]);
}
dataGridView1.DataSource = dtb;
try
{
string strExpression = "ID = 1";
DataRow[] dr = dtb.Select(strExpression); MessageBox.Show(dr[0].ToString());
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}

Thanx mate!
But I still need it to be as I wrote it "DataTable is filled out of a file that makes it ambiguous to decide what type the value is" as seen from my example, can you please try it with my exact code and tell me what modification I would need?? Cuz I think the problem is in the way I'm storing data not in filtering it!

What is the exception you get (particularly what is in exc)? Be a bit more verbose and someone may be able to help.

Paul,
I found my error with this application
By mistake I was not displaying the exc Exception, I was only displaying my own error message
After your question I notice my error and found that computer with windows 2000 had an old version of the MDAC,
I just need to run an early version and everything works OK,
Regards
Rafael
