That would be the best code you can write and the most best help that you can offer your users without tormenting them through the numerous coding horrors that I could speculate from you.

And I was just wondering what the question was. Thanks for clarifying!

I used it successfully for grid.fronend-c# , Backend-sql2005.
Using following code u can auto generate no. from database.
1.open command.
2.use data reader.
and write this code
while(dr.read())
{
int c1=c1+1;
}
c1=c1+1;
dgv.rows[no.].cells[0].value=c1.tostring(); //dgv=datagrid view name

There are so many things wrong with this code it's silly. Thankfully, I will never have to follow you and support/cleanup your code.
Your simple little algorithm does work, though VERY inefficiently, and only when there is but a single user of your database.
When you expand this so more than one user is creating a new record at the same time, your code breaks, so severely, it corrupts the database, puts an enormous load on the SQL server and network carrying the data, and will get slower and slower as the number of records in the table climbs.
Ask youself this. What if a second client ran this same code at nearly the same time? Both clients would get the same last record ID, and both add 1 to it, and both create a new record with the same new ID, but different data. Congratulations! You just corrupted your database to the point where you can't easily recover, if at all!
Your application should never generate it's own sequential record ID's. This should be left up to the database itself, when concurrancy issues like this can be controlled.

How to add autogenerate number in datagrid

You can't. The database generates it so you can only display it.

So you do know how to use Google then? And here I was thinking that you didn't know how to google.

How to convert these code to C#? Thanks!
memset(m_bParameterData, 0, sizeof(m_bParameterData));
Float2IEEE((float)EXTERNAL, m_bParameterData);
|
|
|
|
|
The memset is there to clear out the memory that the pointer is pointing to. I believe you should be able to ignore that here.
As for the other function, I have no idea what it is. Where was it being used before? Is it in an external DLL?

Assuming that you are actually using a DataGridView.
Iterate over the Rows collection, and delete those that have the CheckBox checked.

{
Response.Write("Acrobat Not Running");
}
can we get the reference of the file for which the AcroRd32.exe is applied. If so, How?

If you cannot follow a well laid out tutorial then I suggest changing job/course and trying something less challenging.
