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

ok i removed .AcceptChanges()
now i tried to delete then i had this exception:
Update requires a valid DeleteCommand when passed DataRow collection with deleted rows.

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

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,

did you sign your assembly? Project Properties --> Signing --> Sign the assembly Wink | ;-)

kind regards

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.

Smile | :)
