I have lost access to the Distributor and Subscriber servers, and need to delete the publication.
I managed to delete the (pull) subscription database, locally only, so the subscription still shows as orphaned, on the publisher server.

I am trying to simply delete all replication related components.

I am trying to remove the publication, but I get an error that it cannot be removed due to a connected subscription.

I then try to remove the subscription, usign the script below - but I get a message that the subscription does not exist?

Can anyone help with why?

(Remove Subscription Command)

--Select your publication database



DECLARE @publication AS sysname;

DECLARE @subscriber AS sysname;

--enter your publication name

SET @publication = N'NxPub';

--enter subscriber name

SET @subscriber = N'NxSub';


EXEC sp_dropsubscription

@publication = @publication,

@article = N'all',

@subscriber = @subscriber


i know the usb 3 drive docks
my question is : is there anything faster on the market?  
 or is sata speed comparable to USB 3
in my betting software project i have 2 tables and a query like this:

procedure TMain.Button16Click(Sender: TObject);

ADOQuery8.SQL.Add ('SELECT SUM(W1) as total1, SUM(B1) as total2, COUNT(*) AS TOT');
ADOQuery8.SQL.Add ('FROM Table1');
ADOQuery8.SQL.Add ('WHERE League = '+QUOTEDSTR(adotable2.FieldByName('League').asstring));

It works very well, but i need to get only the first 30 records from table1 and not the whole records.
The table also has a date field called 'data', i made many tests but with no success...
It is a delphi app (embarcadero xe8) with ado components and ms access tables.


I have tried multiple times now and I am at a loss.  The customer has HP G6-1d01dx that has Windows 10 AU on it.  We are attempting to upgrade it to CU.  Every time that it goes through, it fails at 40%.  I keep getting the following error;

"Windows could not configure one or more system components. To install windows, restart the computer and then restart the installation."

This is using the upgrade tool.  I have also attempted to upgrade using a bootable USB but it failed with the picture included.
I have a new UPS 950VA BX950U-GR, just unboxed and plugged to line.
It's correct that no lights are on? If I turn on the ups I see green light flashing

I work at a small catholic school.  We have Epson projectors in our classrooms.  In some rooms we have large screen tvs.  We use PCs, MacBooks, and two different versions of iPads for students/staff.  They vary in age.  We have found that there is no single way to connect to the projector that works for each device.  I am looking for a solution (wireless utility or multiple connectors...iPad (small connector or 30-pin)-to-VGA/HDMI/USB, PC-to-VGA/HDMI/USB) that we could put in each classroom so that little to no instruction time is lost trying to connect student/staff devices to the projector.  Needless to say, finances are a concern.

We are looking at AirServer but does that need to be installed on each device or can it be installed on a single device in the room that would work?  Would a TeamViewer solution work?

Any suggestions would be much appreciated!
What does that mean?  >> solid state drive - 480 GB - SATA 6Gb/s >>
SSD’s use sata protocol?  compared to fibre channel, sas, etc

In a nut shell, plan to have a TSpeedButton,  by the same name on ten forms.
Whenever the button is clicked on any form, want to change the image and caption,
on all forms.
Something like this;

procedure TForm1.Button1Click(Sender: TObject);
  i, f: integer;
  s: string;


  with Application do begin

    for i := 0 to ComponentCount -1 do begin

      if Components[i].ClassName = 'TForm' then begin // or Application.Components[i].ClassType = TForm

        for f := 0 to Formx.ComponentCount -1 do begin

          if Formx.Components[i].ClassName = 'TSpeedButton' then begin

            if TSpeedButton.Name = 'SomethingSpecial' then

              Call another procedure with form and button info
              Set to caption and image

I am trying to operate 2 devices from a Solar/12V battery combination at a location where there is not electricity.   Almost more importantly, I'm trying to understand HOW to calculate the power a device will use every hour.   I'd like answers to questions below.. so I can get this stuff ordered... but if someone also could point me towards a resource that explains the calculation thing where a simple minded fellow as myself could understand it, that would be greatly appreciated.

Item 1 is an IP camera, Power is listed as 12V DC, 4W (I'm arriving at 4W by averaging IR use & non-IR use over a 24hour period, Camera specs say consumption is 2W normal, 6W when the infrared is on)

Item 2 is a Point to Point Antenna, Input Power is listed as 24V, .5A.

I have purchased a gadget that converts 12V to 24V (Input -12v - 13.8v, Output - 24V,2500mA)

PDF Drawing attached, sorry for the crude images, figured if I tried to make it look legit, I'd be laughed off the website.  :o)

My questions are this.
1. I think I understand that if I get a 100W solar panel, and it runs at 80% efficiency for 7 hours a day, I can roughly say I will charge a 12V battery 560watts.   ((100 * .8) * 7)   Correct?
2. is it possible to determine how many watts the two items above will use each hour?
3. Can I come straight off the batter to power both items?  I can't see OUTPUT terminals on the charger controller (like I do with other models).   I haven't purchased this yet, maybe it'll be …

We have a  Dell C3765dnf network printer that has a problem with the network cables easily detaching.

We have tried several brand new network cables and none of these network cables stay attached (even if the tab on the network cable is pulled out).

Currently the network cabled attached to this network cable has had to be taped in.

What can be done to fix this issue so we can tightly attach a network cable that won't become detached?

My son has set up a Raspberry Pi in the home to display images. He enabled FTP and told me to connect via WinSCP. I have done this, and I see all the folders on the Raspberry Pi. However, I cannot upload images or do anymodifications on the raspberry pi due to a permissions problem.

Any ideas what could be the cause of this?

I am logging in with his username and password, which has full rights to the Pi.

Thank you.
I have here seven Hitachi 500 GB SATA drives purchased used.  The drives are definitely SATA and not SAS or Fibre Channel; see the image below.  They appear to be standard SATA drives, that's what the label says they are and that's what I expected.

The drives are mounted in server-style sleds.  There's no manufacturer name on the sled; there's a logo I don't recognize on an oval release button on the front, perhaps someone will know from the picture.  The drives are absolutely clean and dust-free.

As I tested them for function, every last one failed to present to the host system BIOS.  I've tried them on two different systems and the BIOS does not see the drive at all.  Each drive makes a brief "peep", clicks in what would seem to be a recal, pauses about half a second and then cycles through this again.

The seller claims that the drives worked before shipment.  When I pressed further on this, asking specifically whether the drives were individually tested, the response was "They worked in the server."  From this I assume that they were not individually tested for function and the seller equated "works in the server" to "works as an individual drive."

Now I can believe one, two or possibly even three drives DOA but not the whole lot, and I find it hard to believe that anyone would knowingly sell dead drives as working on fleabay.  (Side note:  The seller issued a refund, that's not an issue.)

Possibilities as I see it:

  • The drives were DOA when
A user's Windows 10 Microsoft Surface computer currently has 8 GB of RAM.

Are we able to upgrade the RAM on this surface to a higher amount?

What is the most RAM that the surface can hold?

Where can we order the RAM from? I have already checked and doesn't carry the RAM for Microsoft Surfaces.
Here is a scenario.

I have to forms. Form 1 and form 2. Form 1 is linked to form 2 in the uses clause of form 1. Now i have the ability to use an onlick event of a button on form 1 to show/hide form 2. How do i use the onlick event of a button on form 2 to show/hide form 1?

Its not only this that i want to be doing. I want to be able to access data across two forms that linked.

Currently I am using SAP Xcelsius dashboards, I know these are outdated. would like to know what are best tools or applications similar to Xcelsius where the components can be dragged and dropped and build great visualization dashboards.

Objectives for this dashboards
get real time data from ERPs (SAP, Oracle, etc.,)
if it can send alerts to mail that would be great
get the dashboards on mobile/desktop/tablets
have user restrictions
build country/ Region wise data
Using vmware Site Recovery Manager.  All components are version 6.5.

A specific VM is replicated with vsphere replication, which is valid and up to date.
The protection group it was assigned to declared the VM to be invalid and no longer protected.  Attempts to configure protection fail with complaint that I do not have permission.  Same with attempt to remove the vm from the protection group. Cannot delete the group since it still has objects in it.

I am logged in as administrator @vsphere.local

I was able to remove all other vms from the group and make a new group, protecting the entire set of vms, including the one declared invalid.

So my vms are protected, but I have this ugly red spot on my dashboard that says I have a problem somewhere.  Any ideas how to get permission to clean this up?

I have got AMI BIOS on one of server, how to disable secure boot and make first boot device has dvd rom?
And what was is role administrator/user password role in disabling secure boot?
So i've replaced my old motherboard with a new AsRock motherboard and now I can't get the system to boot, not even BIOS or POST shows up. The computer turns up and everything seems to run, all fans, psu, motherboard lights etc.. So in order to narrow down the problem I've disconnected everything, ALL components, RAM, GPU, HDDs, FANS, everything other than the CPU itself and the problem still persists, nothing shows up on the monitor other than black (i've tried all inputs, d-sub, dvi, hdmi, display, from both the motherboard and GPU). I've tested the PSU with a PSU Tester and it is working normal. So my question is:

How can I determine if its the CPU or the motherboard with the problem? I don't want to have to buy two components if only one is at fault.

Thanks in advance for your help.
What kind of adapter is needed to connect two external monitors to a Lenovo Yoga 720-131kb laptop?

Is it possible to do this without having to purchase a port replicator? If so what kind of adapter is needed?
Is it safe to plug 90 watt power adapter directly into a Lenovo T440 laptop?

Or can this power adapter only be used and plugged into a port replicator?

This macro lists the number of items next to each item when clicking on the top row of a column.

I 'think' this macro may depend on a function and on sheet level code.

I'd like to make it work as a single macro if possible.

Assistance is greatly appreciated.
