hello every body,

i use a datagrid view bounded to a datasource, but i can't update the changes happens in it.
although, i've added the insert, update & delete queries i also use a dataset with a tableAdapter .

and this what iam doing in the onSaveButton_Click:

try
{
dataGridView1.EndEdit();
this.visitorTableAdapter.Update(this.omvDataSet.visitor);
omvDataSet.AcceptChanges();
MessageBox.Show("Changes saved successfully");
}
catch (Exception ex)
{ MessageBox.Show(ex.Message); }
so, what is the right solution to accomplish what i want.

Regards

hi,

what's wrong now? code looks good, but you don't need to .AcceptChanges() because .Update() does it for you. Wink | ;-)

kind regards

Hi,

are you sure you filled all commands of DataAdapter? There are InsertCommand, UpdateCommand, DeleteCommand and SelectCommand (last is filled by constructor, normally). Wink | ;-)

King regards

Installing Windows assembly in GAC

Hi to all

I am trying to add windows assembly to the GAC using the following command in the command prompt.

C:\Program Files\Microsoft Visual Studio 8\VC>gacutil /i C:\WINDOWS\system32\odb
c32.dll

But it is not being install and I am getting the following error.

"Failure adding assembly to the cache: The module was expected to contain an assembly manifest."

I am not getting the reference of the assembly neither in the .NET Assembly nor in the COM objects.

Can anyone tell me how can I install this assembly in the GAC.

Thanks in advance

Amit

Hi,

why would you want that? the GAC is for managed code DLLs only, odbc32.dll is a native code DLL, it is fine where it is.

You don't need curtains with Windows, Microsoft hid some termination commands under "Start", of all places.

Number of days in a year is a constant (varies for a leap year). Number of days in any given month is going to be a constant (except for February in a leap year). Which part of this are you having a difficulty with?

thank you for your replay and you solved the problem and i remembered that if we want to know if February in a leap year or not by divided the year by 4 and if the result is an integer number it will be leap year such as 2004/4=501 this is a leap year and 2005/4=501.25 it's not a leap year
and i'll to try it by code
Many thanks for all

Ooh - not quite. If it's a century, it has to be divisible by 400 to be a leap year, so 2000 is a leap year and 2100 isn't.

use modulus (provides the remainder after a division) not divide...

if(year % 4 == 0)
    //is leap year
else
    //not leap year
