In Delphi 10.2 Tokyo:

I created a package called TestFrameCompPkg that has a frame TTFrameComp as a component. The package build and install work as expected.

My problem occurs at design time with the ShowEdit and ShowLabel properties. When I place the component on the form, the property changes don't Hide and Show the ToolBar components in the IDE. But each does function normally at run time.

How do I get the show/hide properties to function at design time?


Code Example is below:

FrameComp.dfm
object TFramComp: TTFramComp
  Left = 0
  Top = 0
  Width = 800
  Height = 291
  TabOrder = 0
  object ToolBar1: TToolBar
    Left = 0
    Top = 0
    Width = 800
    Height = 29
    Caption = 'ToolBar1'
    TabOrder = 0
    ExplicitLeft = 192
    ExplicitTop = 48
    ExplicitWidth = 150
    object Edit1: TEdit
      Left = 0
      Top = 0
      Width = 121
      Height = 22
      TabOrder = 0
      Text = 'Edit1'
    end
    object Label1: TLabel
      Left = 121
      Top = 0
      Width = 31
      Height = 22
      Caption = 'Label1'
    end
  end
end

Hello Experts:

I'm adding a Radeon VEGA 56 Video Card to a desktop system.  The stock power supply is 280 Watt.

The machine has an AMD A10 9700 3.5GHz Processor and a 512GB SSD HDD.  32GB RAM

Will this work or do I need to upgrade the power supply?

Thanks

I am new to Angular and using Angular 6 CLI. Problem I have is, I have a JSON object that I am getting data from http.get and then trying to parse out different JSON blocks in an object. Then I am passing these objects to respective components. I can see that in the subscribe block the data is populated correctly but outside subscribe block, those objects are 'undefined'.

So from any .ts file, the objects outside subscribe block is undefined. However, I could access data from template files that is from .html files.

for example,  below is where I am calling service from "Component A" so component A has "myappRoot", "myapp", "myproblem"..etc all objects of custom type defined. The custom type is basically interface which I am exporting from index.d.ts file. So objects are populated  inside subscribe block is fine. But if I do console.log(this.myproblem) it comes as undefined outside ngOnInit(). If I pass this object to "Component A HTML" file like {{ this.myproblem? | json}} it prints correctly. but if I pass it to some other component B like <app-component B [myproblem] = 'this.myproblme' ></app-component B> and try to do console.log(this.myproblem) in component B.ts file, it comes as undefined.  Is it due to async nature of observables? How do I solve this?

ngOnInit() {
    // lets  make a call and initialized the root object and children
    this.myproblemService.getmyproblem().subscribe(root => {
      this.myappRoot = root;
      this.myapp = root.myapp;

Dear experts,

I have wireless keypad for my laptop -windows 10.

I use it both for my  normal text typing as well as for c language.

Is there a separate set-up required for keypad when using it for typing languages syntax (for instance || and \)

The reason is I do see the key strokes on the keypad but when I type it types different characters.

Kindly guide me to switch between these two requirements.

Thank you

I have a Gigabyte z370n wifi MB.  It supposedly supports 3 displays. 2x HDMI and 1 Display Port.  My 2 HDMI's work but only mirrored.  The 3rd Display port does not work. It is using an adapter that is HDMI to display port. So there are two issues. Why won't the Computer pick up that it is multiple displays so I can expand separate displays and two, why wouldn't the display port work.  I am not using an additional GPU.  I'm only using the built in for now.  I was thinking maybe some software might help, but I couldn't find any drivers or software on the Gigabyte website.  Thoughts?

Free Tool: Site Down Detector

Helpful to verify reports of your own downtime, or to double check a downed website you are trying to access.

One of a set of tools we are providing to everyone as a way of saying thank you for being a part of the community.

I built a desktop.  When I switch on the power and push the power button, the system fans come on but nothing else seems to come on.  Also, the system fans only come one when the 24 pin power cable is plugged in.  If I unplug the 24 pin and just plug in the 8pin CPU power, nothing happens.  No display activity, no USB activity, either way, they are plugged in.  Everything is brand new.

First, should I be plugging both in?  One thing I have noticed is that the motherboard is a Gigabyte Z370N WIFI with has a 4 pin heat sync plugin.  I have a Corsair H55 heat sync which has a 3 pin plug.  Since the motherboard is designed for a four pin plug, I wonder if that is why nothing will turn on?  See the image of the motherboard specs.

Also, one thing to note, when I turn on the power switch on the back, a light flashes on the motherboard once quickly, then nothing.  But as mentioned before, as long as the 24 pin cable is plugged in, the system fans still stay on.  

Another Test: Tested the ThermalTake TR2 Power supply with the 24pin Paperclip test. The fan in the Power Supply runs just fine.

I am installing a Gigabyte Z370N Motherboard with a Powerspec 430 power supply.  I have connected the main 24 pin power connector, but I was wondering if I needed to connect an additional power connector for the CPU?  It looks like there is an 8 pin connector on the Motherboard.  I have a split 6pin / 2 pin and a 4 pin connector.   Do I need to connect to it, I'm not sure which cable to connect or what slot. Do I connect the 4 pin to the 6 pin connector?  If so,Gigabyte Z370N WIFI which side?  See image.

Asus Motherboards will not boot.  CPU fan spins for 5 seconds then stops, no post, no beeps.  Have tried multiple CPUs, multiple RAM sticks, multiple power supplies, and 3 different Chassis.  I've also bench tested this (MB/CPU/RAM/PSU) without success.  This happens with 5 motherboards, all the same type, brand new from ASUS: Z370-G.  I've swapped all the components I can think of.  Any Experts can think of something I missed?  It's hard toi believe an entire box of MBs is bad, but seems to be leaning that direction.

Thanks.

We have an APC AP9631 network card for a UPS that I think is defective. When I assign it an IP address through the front panel of the UPS, the settings don't save. I replaced the card with another one and it works.

APC wanted me to try doing a remote connect through a serial cable but that didn't seem to work. Now we have had to send the UPS to site and I can't get to it anymore.

APC says they haven't confirmed the card is defective so can't replace it. Has anyone seen the behaviour above and were still able to fix it?

This works on an access form.

=Nz(DLookUp("[Rebate]","Rebates",("[foo]=[foo] and ([DMS]) Between [MSH] And [MSL] And ([DDoses]) Between [VH] And [VL]")),0)

But in a complicated scenario I need it to operate to update a table after a value is changed on another part of the form.
I've tried for days and I can't get it to work.  

Rebate, DMS and DDoses are numbers while foo is text

Here, I'm trying to just break it down into components to isolate anything.

Dim db As Database
Set db = CurrentDb

Dim xfoo As String
Dim xDMS As Long
Dim XDDoses As Long
Dim varx As Long

xfoo = Forms!PST.Form![PST1 Subform]![foo]
xDMS = Forms!PST.Form![PST1 Subform]![DMS]
XDDoses = Forms!PST.Form![PST1 Subform]![DDoses]

varx = DLookup("[Rebate]", "[Rebates]", "[foo]= " & xfoo)


DoCmd.RunSQL "Update PST1 Set PST1.Cohort = '" & varx & "'"

I am looking for a dock that reads old IDE, Ultra IDE, and also old smaller laptop HDs as well as any type of SATA HDs.  I would prefer one with a USB 3.0 connection.  I've looked all over and haven't been able to find someone that offers one.  One other option that I just thought of would be to use some type of converter with it with one end of the converter going to the HD and the other end going to the dock.  Example old IDE drive connected to the converter and then the converter connected to the dock.  Please advise if you can find a dock that will connect them directly with the dock and if there are converters available, and if so, will they work with a dock.

My company has an Epson Expression 1680 scanner that has stopped working. The manual for this scanner has been attached to this question. Epson-1680-scanner-exp168uu4.pdf

We need to order a replacement scanner and have found this scanner for sale on Amazon:

https://www.amazon.com/gp/product/B01K3777HS/ref=ask_ql_qh_dp_hza

(which is identified as an "EPSON 1680 - EPSON PERFECTION 1680 W/ADF" scanner.

My question about this scanner listed for sale on Amazon is whether or not it is the exact same model as our existing Epson Expression 1680 scanner.

We need to make sure that we order the exact same model scanner.

I have already asked this question on Amazon but haven't yet received a reply.

I have replaced the power cord with several known good power cords and have plugged this scanner into different power plugs but it still won't power on.

What can I do to troubleshoot or fix this issue?

Does this scanner have a fuse or similar item that can be replaced that might fix this issue?

Attached is the manual for this scanner.

How to apply thermal paste for maximum heat transfer.
Key to your CPU's ability to stay cool is to use the right amount of thermal paste and apply it correctly. In other words you want as much thermal conductivity between CPU and the cooling block.
Use a quality thermal paste and apply it in a manner that prevents air pockets, spreads evenly, thinly and thoroughly between the CPU and cooling block.
There are two metal surfaces that will make thermal contact. Make sure both surfaces are clean. If your unsure, clean both surfaces with 99% alcohol and a dust free cloth. A  coffee filter works great. The alcohol will naturally evaporate in a second or two. Then we'll "wet" one surface and "mud" the second.
When wetting a surface, your finger is best and easiest. Clean your finger with 99% isopropyl alcohol, and when dry, dab your finger with a small amount of thermal paste. Spread it as quickly as you can, but be sure you wet 100% of the surface. How thin is a properly wetted surface? If you can see the metal surface beneath, and also see evidence that it covers the surface entire, you did it right!
Mudding the second surface is easy. Dab a small amount of the grease and use a credit card and begin spreading the compound around. The edge of the card will pick up excess paste and can be reused to fill any area that doesn't have enough of the paste. Spread it as thinly and evenly as you can. Put it on to thick allows the paste to boil and form bubbles. When done, it'll be too thick to see the metal below and look evenly spread …

Machine is HP Pavilion HPE h8-1100z
BIOS is corrupted by malware.
No access to OS, installing new OS not possible.

How can one recover (re-flash) the BIOS?
From an USB drive yes, but HP's Hardware Diagnostics utility does not support any of the Pavilion HPE for BIOS recovery..
Has anyone recovered the BIOS on a Pavilion HPE lately? The BIOS update exe (from HP support site) does not offer anymore the option of creating an USB drive.

Any other option other than recycling this expensive machine?

I have a new Samsung Galaxy S9 which replaces a Samsung Galaxy S6 and I have two issues which are probably connected:

a) I cannot use the App "Wifi File Transfer Pro" - when I launch the App on the phone it gives an IP address to enter into my browser on the PC, but when I enter this address it will not bring up the page - the connection eventually times out; on the Galaxy S6 this works perfectly

b) I have an app I have written in Java which has components running on the phone and my PC, which I use for transferring various files between the phone and my PC - again this has worked perfectly for many years on the Galaxy S6, but on the S9 it fails to connect:  the phone component successfully wakes up the PC component which does its thing and then tries to connect to send the result, but the java command connection=new Socket(host, PORT) times out with the error message "java.net.ConnectionException: Connection timed out: connect"

It looks like a firewall issue, but it's not the firewall on my PC since I've tried disabling that temporarily.   It may be a firewall issue on the Samsung S9 but I can't see how to configure that.   I've tried tweaking the Setting "Phone visibility" but that doesn't seem to solve the issue.

Any thoughts?

I'm trying to automate a campus solutions business process through an app engine calling CI's.  One of the components has a OK/Cancel popup warning box on the save event (under certain data conditions) that require the user to click OK on before it will save.  Is it possible to code the CI to issue the OK response, so the CI can complete the save?  

Thanks!
