OK, so my code now looks like this:
<br />
DataRowView drv = dataSet_Suppliers.Tables[0].DefaultView.AddNew();<br />
drv["SupplierID"] = System.DBNull.Value;<br />
... more field assignments here ...<br />
drv["HomePage"] = "";<br />
drv.EndEdit();<br />
oleDbDataAdapter_Suppliers.Update( dataSet_Suppliers, "Suppliers" );<br />
When I call the "Update" command, an OleDbException is thrown.
Any other thoughts?

I try to use the Win32 function "LogonUser". But I always get "false".
I add a user in windows "myuser" and the password is "mypassword". The domain is "mydomain".
Then I use it like this :
LogonUser("myuser", "mydomain", "mypassword", LOGON32_LOGON_INTERACTIVE, LOGON32_PROVIDER_DEFAULT, ref token);
But the return value is always false.
Are there any possibilities to check if user and password is ok ?

Thanks for the link.
Have you ever tried that function before ?
I'm trying it using:
Username = ""
Password = ""
Domain = ""
And..the return value is TRUE...
That means user is valid.

This means that the current user who is logged in is already logged in - imagine that!

I am using fingerprint reader.
Need help to capture the image in my application from fingerprint reader.
What's the mechanism used to capture image in fingerprint reader. Does it scans the image?
|

You'll need the SDK from the manufacturer of the Fingerprint Reader. Without it, you're not going to get anywhere.

Hi,
I am trying to use C# to execute the following procedure.
call RESOURCE_DEVELOPMENT.PHILIPS_REPORTS.ConfirmUDFExists('COM_X');
The error is:
ORA-12154: TNS:could not resolve service name
This is the c# code that I am using.
please note that the above procedure works fine in oracle.
objConn = DatabaseConnection.GetConnection(objContext);
objConn.Open();
objCmd = new OracleCommand(strSQL, objConn);
objCmd.CommandText = strSQL;
objCmd.CommandType = CommandType.Text;
objCmd.ExecuteNonQuery();

Cross posting it in as many forums on code project as you can until some one gets onto you for cross posting.

You can dynamically create the context menu when the click is performed. Also you can use one context menu and just clear the menu items and add new items at runtime. The code below is .NET 2 same logic different control in .NET 1.1
contextMenuStrip1.Items.Clear();
ToolStripItem ts = null;
for(int i=0;i<5;i++){
ts = contextMenuStrip1.Items.Add(i.ToString());
}
contextMenuStrip1.Show();

We can create context menu in this way but also we need to handle events for these context menus. To do so we can create a common event for all menu items and then based on the context name respective code can be executed.
Impossible itself says I M Possible.

duh
private void button1_Click(object sender, EventArgs e) {
contextMenuStrip1.Items.Clear();
ToolStripItem ts = null;
for(int i=0;i<5;i++){
ts = contextMenuStrip1.Items.Add(i.ToString());
ts.Click += new EventHandler(ts_Click);
ts.Tag = [PUT SOMETHING HERE TO ID IT]
}
contextMenuStrip1.Show();
}
private void ts_Click(object sender, EventArgs e){
...
}

All you have to do is bind your events at the time you create each context menu item. You would basically be doing in abstract code, what the designer does with hard coded code.
foreach ( string element in myListofThings )
{
ToolStripMenuItem menu = new ToolStripMenuItem();
menu.Name = element.ToLower();
menu.Text = element;
menu.Click+=new SystemEventHandler(HandleContextClick);
myContextMenu.Add( menu );
foreach ( string subElement in SubElementList )
{
ToolStripMenuItem submenu = new ToolStripMenuItem();
blah blah blah
submenu.Click+=new SystemEventHandler(HandleSubContextClick);
}
}
