I need to Load 4thousand record into a datagrid for the user to choose.
After the user click the row, I will save it.
Now, How can I remove the uncheck row.
Dim myDelRowArray() As DataRow = dtRvDetail.Select("check = false ")
Me.dtRvDetail.Rows.Remove(myDelRowArray) <-- I know there is error, since i
cannot delete the datarowarray.
Any simple and easy way ??
thanks a lot

Hi,
I have read many of the copius entries on the subject of IE performance (or
the lack thereof) when populating Select Lists.
I don't mind the insert performance so much, (I get 100x120byte rows
inserted/sec up to 500, and 100rows/6secs up to 3000, which isn't great but
then the Row Count is clicking away for the user to see and they can hit the
"cancel" button at anytime, so overall I'm happy), what really disappoints
me is the...

Hi,
I'm not 100% sure that this is an Access problem. A friend of mine has
an Access 2003 database. Occasionally he brings a copy to me so that I
can import some of his data into my Access 2003 database. For years he
has done this with no problems by bringing his copy on a CD.
However, last week he put his database onto a memory stick and brought
it to me. When I try to open the database, I get the error "The Visual

Hi,
I realize that eval() is generally discouraged, but I've found myself
wishing that I could execute user-generated code.
One idea I've seen is to use token_get_all(), and then make sure no
T_STRING tokens match known "dangerous" function names.
Where could I find such a list of "dangerous" functions? What are the
pitfalls of this approach? Is there any way to safely allow user-

I have been perusing various blogs and MSDN pages discussing the use
of event properties and the EventHandlerList class. I don't believe
there's anything special about the EventHandlerList class in this
context, in fact some articles from pre-2.0 suggest using any
collection class of your choice. So my questions focus more on the
syntax of event properties provided by the "event" keyword in C#.

Hello,
After a successful installation of Xubuntu, I am posting this question.
In Windows XP we select option "Safely remove hardware" before we remove a USB drive (or Pen drive) from a computer. What is Linux equivalent of "Safely Remove USB drive" of windows.
I think if we unmount a USB drive then this is equivalent to "Safely remove USB drive" of XP. But I'm not sure and therefore I am psoting this here.
Thanks in...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
