Hello Experts!!
I am using following code inwhich instead of current value it takes null.I am using it at cell leave event of datagrid.
<pre>int ind = dataGridView1.CurrentRow.Index;
if (call == 1 ||call==2)
{
arr[x++] = (string)dataGridView1.Rows[ind].Cells[1].Value; //Error here
call++;
}

Let me turn my mind reader on...
trying to read error...
dense object detected...
error: can't read mind, shutting down now.
What error do you get?
What's the code supposed to do?
What does it do?
And what is your question?

Define "current value" in the context of the code you have shown. There is nothing in the code called that. The nearest is "CurrentRow".
KIDYA wrote: arr[x++] = (string)dataGridView1.Rows[ind].Cells[1].Value; //Error here
What sort of error? At a quick glance there are at least 8 possible points of failure on this line.

Hi there,
I'm building a windows application using Visual Studio 2005.
1- I built the GUI and the database table needed.
2- I biult a SQL table with the fields needed.
3- I used the VS2005 wizards to establish connection and to create the dataset and table adapter.
4- I added a gridView to the form bound to the defalut data source enerated by VS.
5- I added a button with this code inside the click method:
/////////////////////////////////////////////////////////////////////
surveyTableAdapter.Insert(q1.ToString(), q2.ToString(), q3.ToString(), q4.ToString(),
q5.ToString(), q6.ToString(), q7.ToString(), q8.ToString(), name.Text, email.Text,
phone.Text, address.Text, post.Text, comments.Text, mailList.Checked.ToString());
this.surveyTableAdapter.Fill(this.surveyDataSet.Survey);//this is to populate the gridview upon a click
MessageBox.Show("Thank you for your participation in this servey.");
/////////////////////////////////////////////////////////////////////
6- The problem is that when I click the button I see the changes in the gridview, but when the program is re-executed, nothing is found in the table.In other words, changes are not saved.
7- I built a MS-Access database and connected it to the GUI, but the same thing happened.
I want to reiterate that i'm using the default cod and settings of the VS2005.
Can anybody help me in that?
Thanks in advance.

Have you called Update on the TableAdapter and AcceptChanges on the Table in the DataSet?

I don't read unformatted code; use the PRE tags (e.g. through the "code block" button under the edit box.

Do you want to display the data or you want to create task which collects data between this time?
try to explain your problem clearly

A formal analysis of the Algorithm you suggested would be O(n) which isn't so bad.

Hi!
I want to catch all messages of an external application in my application. For exp. if user is using Microsoft word and if he/she clicks on file menu, my application should catch the message that File menu is clicked. I searched on SetWindowsHook API but could not get any C# sample similar to my target. Can anyone have any idea how to do it in C#?

I suspect you're looking for this[^]. Pay particular attention to the Notes section on limitations of .NET.
However, you aren't interested in all messages - you should only be interested in certain messages. Do you want your application, for instance, to know that Word responded to a Paint message?

This is like asking "How to brush my teeth with sand?". Sure, it will work, but the results may not be as shining.
If you're writing global hooks, for the love of God, please write it in C or C++. Use the .NET framework for what it is supposed to be used. If you have a genuine reason why you want to do this in C#, can you please provide it?

Hi Rajesh
Its true that VC++ is a better language for global hooks with call back functionality but the question was specifically asked for C# for whatever reason. So if you dont know the answer then please dont reply with criticism instead try to look for the answers that would benifit all of us.
