I made a DataGridView on my form and bound it to data from my database. Everything works fine.
What I want is to allow user to add rows to my database using this DataGridView. I set the 'AllowUserToAddRows' property to true. When running the application, I can add new rows to my DataGridView, but no changes are made to database.
How to make it?
Thank you very much in advance

You must update database from datagriview. Add this code into your app
using System.Data.Oledb;
DataTable dt = (DataTable)datagriview1.datasource;
OledbDataAdapter adap = new OledbDataAdapter ("Select * from <tablename> where <primaykey> = 0 (or "")", con); //con = new OledbConnection(<connectionstring)
oledbcommandbuilder buider="new" oledbcommandbuilder(adap);
adap.fillschema(dt,schematype.sourced);
adap.fill(dt);
bool="" result="(adap.Update(dt)==1)?true:false" ;
="" true="" :="" is="" successfull.="" otherwise="" not.
=""

Thanks!
I just wonder, if this could be achieved automatically? Just like getting info from database into DataGridView is..

Why did you think so easily ?

update the database with the values from the datagrid, as soon as a new row is added to the datagrid.

Hi All,
I'm trying to get the exit time of a process which has been initiated using the process class. An event has been written which will be triggered when the process is being closed. But the problem here is, the event is not getting triggered. Here is the code:
ProcessStartInfo startInfo = new ProcessStartInfo();
startInfo.FileName = "notepad.exe";
startInfo.Arguments = @"E:\shared\perdata.txt";
startInfo.WorkingDirectory = @"C:\Temp";
startInfo.WindowStyle = ProcessWindowStyle.Maximized;
oProcess.EnableRaisingEvents = true;
oProcess.Exited += new EventHandler(ProcessExited);
oProcess = Process.Start(startInfo);
Event to be called:
public void ProcessExited(object sender,System.EventArgs e)
{
MessageBox.Show(oProcess.ExitTime.ToString());
}
Any help would do. Thanks in advance

The event is getting triggered. I've found what is wrong with this.
Instead of using startInfo.filename & startInfo.arguments, I should use oProcess.StartInfo.filename.
Anyway, thanks for the suggestion.

Hi,
Are you trying to implement a log on web service ? I think, you can use the SqlMembershipProvider for this, but I am not sure about it.

i think should be cause my work i am doing is that i am a administrator and i am supposed to create a new user in the aspnet_users database. but i do not know how to write the source codes for it on my web service.May I know how to do it?

You can just execute the aspnet_Membership_CreateUser stored procedure from the database with appropriate parameters. Even if you want to add some user to a particular role then you can use aspnet_UsersInRoles table.
hope this helps. Just go through the procedure first to see whether it solves your problem and you are able to understand what it is doing. If you are going to create user on live site, TAKE BACKUP FIRST !!!!!!
For you reference here is a link from MSDN :-

What will you do with this service ? I mean, by logging all the keyboard strokes, for what you will use them.

I know how to write that in C-Language
using TSR(Terminate But stay Resident).
Achieving this is very easy in c-Language.
Juts 10 lines of Code that uses
getvect()
setvect()
keep()
functions.
If U have enough time
try to learn these functions,
how to create C dll(Using MS Compiler)
and how to import them in .NET using
DllImport method.

My code is here
private void copyToolStripMenuItem_Click(object sender, EventArgs e)
{
DataObject obj = dataGridView1.GetClipboardContent();
str = obj.GetText(TextDataFormat.CommaSeparatedValue).Substring(1).Split(',');
}
private void pasteToolStripMenuItem_Click(object sender, EventArgs e)
{
try
{
DataGridViewRow dgvRow = dataGridView1.Rows[0];
for (int i = 0; i < str.GetLength(0); i++)
dgvRow.Cells[i].Value = str[i];
dataGridView1.Rows.Add(dgvRow);
}
catch (Exception ex)
{
}
}
But it throws an exception "Rows cannot be programmatically added to the DataGridView's rows collection when the control is data-bound"
I am very confused. Kindly help me. Thanks
It seem to be a solution or an answer.
