  • Can't open Control Panel or IE

    - by Josh
    I have a XP computer where when ever I try to open Control Panel nothing happens, nothing flashes on the screen. Same thing with Internet Explorer. I've scanned the computer with Malwarebytes and Avast, Malwaresbytes found some Adware which it removed without problems. Avast found nothing. I looked at the running processes with Process Explorer, nothing malicious running. And looked at a Process Monitor output when I tried to run IE, nothing obviously wrong. The process just decides to exit. What can I try next? I would suspect corrupt IE install but Control Panel doesn't work either. UPDATE: Nether work in Safe Mode under the user account. (only 1 user on the computer) But in Safe Mode, under the built in Administrator account, they work. So what ever is broken, is only broken in the one account. Anything under the HKCU registry key that could break this?

  • Windows 7 boot order and locations

    - by Russ C
    Hi, Long story short, a program that shouldn't have been run on this machine has been, and it's created a naughty .sys file that is being loaded right after pci.sys (as determined by NBTLog.txt) I've had a look a BCDEdit, EasyBCD and a number of Registry keys but I can't seem to determine where about winstart.exe actually gets the list of sys files to load from! The sys file itself is running in high elevation and appears to be defeating all attempts to remove it; I could (probably should) make a Linux USB boot disc and use it to delete the sys file, but I'd really appreciate understanding the mechanics here. ((FWIW: the problem stemmed from a sibling running a Trainer for some game; he has been suitable chastised))

  • Excel controls not visible for certain users

    - by Nossidge
    One of the users of an Excel program I've written is having a weird problem. None of the control objects (Command Button, ComboBox, etc.) are visible to him when he opens the file on his laptop. He is using Excel 2003, the same version I used to create the program, and enables macros using the pop-up when the file loads. I have Googled this, and have found these people who seem to be having the exact same problem, with various versions of Excel. Unfortunately, none of their questions were answered. I can't really explain it any better than this user: If I enter design mode and pull a control from the control toolbar onto a sheet all I see are the drag handles. When not in design mode I have to feel around with the mouse and can click the button which executes the button click code correctly and opens another sheet where again I have to feel around for the buttons to return me to the original sheet. The button I managed to click is now visible but as soon as I click anywhere on the sheet it disappears. I have verified that the visible property of the buttons is set and that the Show All Objects on the Options View tab is selected. If I pull buttons from the Forms toolbar onto a sheet they are visible. If I try to find Objects using F5 when not in design mode Excel reports no objects on the sheet. So, Super Users, can you help? UPDATE: Thanks for your replies, but much like the person in the ozgrid link, the problem has gone away. Not sure why it went, but I can confirm that the user rebooted again and also started up other Excel files that didn't contain controls in the interim. Perhaps that fixed it, or maybe it'll be back again. I'll keep udating with progress, and close if the problem doesn't reoccur for the next few days. Thanks again.

  • Using Zentyal to control several servers

    - by user1301428
    I am currently in the process of creating a home server, made up of several virtual machines, each running a different type of server (i.e. a file server, a multimedia server, a firewall and a print server as of now). Today I discovered this new software, Zentyal, which looks interesting for system and network administration. However, I haven't understood one thing: can it be used only with its preconfigured packages or can it also be used to control other servers running other programs (in my case, the four virtual machines)?. Also, would you suggest to use such a program or do you think it's better to control each server on its own?

  • How can I remap control+e to escape+control+e in iTerm2?

    - by cwd
    I have set up a few custom keyboard shortcuts in iTerm2 to easily move the cursor around with the arrow keys, but now I'd like to remap control+e to be escape, control+e because bash 4.2 no longer auto-expands variables using the tab key. I know I've done the first part correctly in choosing the keyboard shortcut to remap, but I don't understand how to look up the correct escape sequence (or hex codes) to send in the bottom section: I reference they keyboard codes but that wasn't much help. How can I remap this, and how can I look up the codes in the future? (No luck with Google) Update @db - thanks. To save others trouble I also found a cool util Key Codes.app which can be used to find key codes:

  • How to mount a iSCSI/SAN storage drive to a stable device name (one that can't change on re-connect)?

    - by jcalfee314
    We need stable device paths for our Twinstrata SAN drives. Many guides for setting up iSCSI connectors simply say to use a device path like /dev/sda or /dev/sdb. This is far from correct, I doubt that any setup exists that would be happy to have its device name suddenly change (from /dev/sda to /dev/sdb for example). The fix I found was to install multipath and start a multipathd on boot which then provides a stable mapping between the storage's WWID to a device path like this /dev/mapper/firebird_database. This is a method described in the CentOS/RedHat here: http://www.centos.org/docs/5/html/5.1/DM_Multipath/setup_procedure.html. This seems a little complicated though. We noticed that it is common to see UUIDs appear in fstab on new installs. So, the question is, why do we need an external program (multipathd) running to provide a stable device mount? Should there be a way to provide the WWID directly in /etc/fstab?

  • Visual Studio Express 2012 - Moving items to tab control loses actions

    - by JohnP
    VS 2012 Express on Windows 7 Professional, this was pre SP1 install. I have a windows form that I had several elements (Listboxes, buttons, text and labels), with some actions associated with changing indices on the list boxes and of course the button actions. I decided I wanted to add a tab control to enable a second tab with a different feature set, so I copied/cut/pasted all of the original items to a tab control that I added. When I did this, all of the elements lost their click action in the events window. I had to go and re-associate all of them. Is this a normal behavior/known issue, or is there some method to move controls that I am not aware of?

  • HP Pavilion dv3 volume control display driver on Windows 7

    - by Farinha
    I've recently bought an HP Pavilion dv3-2150ep and I'm having a hard time getting the volume control display to work as expected. The control is a back-lit touch-sensitive bar above the keyboard. Now the buttons to turn the volume up and down actually do it, but the lightning is not changing at all. The mute button does change color when toggled. I'm not sure if I'm missing any drivers here (I've installed all of those on the HP support page that seem to have something to do with sound and/or display) or if I have to activate this somewhere. Any ideas?

  • What options exist when the vendor does not supply an ADB driver for an Android device?

    - by STATUS_ACCESS_DENIED
    So I bought an Android phone and the vendor does not offer any drivers whatsoever. The Android SDK and the drivers that come with it don't seem to work with the device, but the device itself reports as Android 2.2.1. Other users have reported that the drivers of the Nook Color worked for them, but I cannot confirm this, after trying. What options do I have to connect to the device (and ultimately to root it)? Is it truly just the .inf file that I need to manipulate in order to make the device ID known to Windows? After all there are tools to figure out those strings while the device is connected (although "unknown") ...

  • Text after Control Sequence

    - by SPAM SPAM SPAM SPAM
    I am trying to parse the output of a command that expects to be writing to the screen. It has data separated by move-to-origin control sequences (for the VT220, ESC[1;1H). I only need the last part (i.e. after the last move-to-origin). I have tried doing this multiple ways (primarily awk and sed), but the problem is always that parts of the control sequence have special meaning (to the program, not just to the shell), and I cannot quote them when I substitute tput's output. Any suggestions?

  • USB mass storage couldn't get mounted

    - by revo
    It's my android phone SD card which was indicated damaged by android yesterday night, out of the blue! I put it directly to a USB port with a USB SD card holder case, so in that way I can recover it with TestDisk, which I had experienced before on a similar situation. I also noticed that there is a change in file system and capacity: File System : RAW Capacity : 0 (unknown capacity) Also TestDisk doesn't show it on its partitions list. A 2 GB SD card is not that important in price but I've a lot of files and medias which I need them. Used a mini card reader, TestDisk displayed it on its list but a quick search and or a deep search doesn't have any results No partition found or selected for recovery and then I should quit the program.

  • Connecting Android device to multiple Bluetooth serial embedded peers

    - by TacB0sS
    I'm trying to find a solution for this setup: I have a single Android device, which I would like to connect to multiple serial embedded devices... And here is the thing, using the "Normal" way to retrieve the Bluetooth socket, doesn't work on all devices, and while it does, I can connect to multiple devices, and send and receive data to and from multiple devices. public final synchronized void connect() throws ConnectionException { if (socket != null) throw new IllegalStateException("Error socket is not null!!"); connecting = true; lastException = null; lastPacket = null; lastHeartBeatReceivedAt = 0; log.setLength(0); try { socket = fetchBT_Socket_Normal(); connectToSocket(socket); listenForIncomingSPP_Packets(); connecting = false; return; } catch (Exception e) { socket = null; logError(e); } try { socket = fetchBT_Socket_Workaround(); connectToSocket(socket); listenForIncomingSPP_Packets(); connecting = false; return; } catch (Exception e) { socket = null; logError(e); } connecting = false; if (socket == null) throw new ConnectionException("Error creating RFcomm socket for" + this); } private BluetoothSocket fetchBT_Socket_Normal() throws Exception { /* The getType() is a hex 0xXXXX value agreed between peers --- this is the key (in my case) to multiple connections in the "Normal" way */ String uuid = getType() + "1101-0000-1000-8000-00805F9B34FB"; try { logDebug("Fetching BT RFcomm Socket standard for UUID: " + uuid + "..."); socket = btDevice.createRfcommSocketToServiceRecord(UUID.fromString(uuid)); return socket; } catch (Exception e) { logError(e); throw e; } } private BluetoothSocket fetchBT_Socket_Workaround() throws Exception { Method m; int connectionIndex = 1; try { logDebug("Fetching BT RFcomm Socket workaround index " + connectionIndex + "..."); m = btDevice.getClass().getMethod("createRfcommSocket", new Class[]{int.class}); socket = (BluetoothSocket) m.invoke(btDevice, connectionIndex); return socket; } catch (Exception e1) { logError(e1); throw e1; } } private void connectToSocket(BluetoothSocket socket) throws ConnectionException { try { socket.connect(); } catch (IOException e) { try { socket.close(); } catch (IOException e1) { logError("Error while closing socket", e1); } finally { socket = null; } throw new ConnectionException("Error connecting to socket with" + this, e); } } And here is the thing, while on phones which the "Normal" way doesn't work, the "Workaround" way provides a solution for a single connection. I've searched far and wide, but came up with zip. The problem with the workaround is mentioned in the last link, both connection uses the same port, which in my case, causes a block, where both of the embedded devices can actually send data, that is not been processed on the Android, while both embedded devices can receive data sent from the Android. Did anyone handle this before? There is a bit more reference here, UPDATE: Following this (that I posted earlier) I wanted to give the mPort a chance, and perhaps to see other port indices, and how other devices manage them, and I found out the the fields in the BluetoothSocket object are different while it is the same class FQN in both cases: Detils from an HTC Vivid 2.3.4, uses the "workaround" Technic: The Socket class type is: [android.bluetooth.BluetoothSocket] mSocket BluetoothSocket (id=830008629928) EADDRINUSE 98 EBADFD 77 MAX_RFCOMM_CHANNEL 30 TAG "BluetoothSocket" (id=830002722432) TYPE_L2CAP 3 TYPE_RFCOMM 1 TYPE_SCO 2 mAddress "64:9C:8E:DC:56:9A" (id=830008516328) mAuth true mClosed false mClosing AtomicBoolean (id=830007851600) mDevice BluetoothDevice (id=830007854256) mEncrypt true mInputStream BluetoothInputStream (id=830008688856) mLock ReentrantReadWriteLock (id=830008629992) mOutputStream BluetoothOutputStream (id=830008430536) **mPort 1** mSdp null mSocketData 3923880 mType 1 Detils from an LG-P925 2.2.2, uses the "normal" Technic: The Socket class type is: [android.bluetooth.BluetoothSocket] mSocket BluetoothSocket (id=830105532880) EADDRINUSE 98 EBADFD 77 MAX_RFCOMM_CHANNEL 30 TAG "BluetoothSocket" (id=830002668088) TYPE_L2CAP 3 TYPE_RFCOMM 1 TYPE_SCO 2 mAccepted false mAddress "64:9C:8E:B9:3F:77" (id=830105544600) mAuth true mClosed false mConnected ConditionVariable (id=830105533144) mDevice BluetoothDevice (id=830105349488) mEncrypt true mInputStream BluetoothInputStream (id=830105532952) mLock ReentrantReadWriteLock (id=830105532984) mOutputStream BluetoothOutputStream (id=830105532968) mPortName "" (id=830002606256) mSocketData 0 mSppPort BluetoothSppPort (id=830105533160) mType 1 mUuid ParcelUuid (id=830105714176) Anyone have some insight...

  • Table Name is null in the sqlite database in android device

    - by Mahe
    I am building a simple app which stores some contacts and retrieves contacts in android phone device. I have created my own database and a table and inserting the values to the table in phone. My phone is not rooted. So I cannot access the files, but I see that values are stored in the table. And tested on a emulator also. Till here it is fine. Display all the contacts in a list by fetching data from table. This is also fine. But the problem is When I am trying to delete the record, it shows the table name is null in the logcat(not an exception), and the data is not deleted. But in emulator the data is getting deleted from table. I am not able to achieve this through phone. This is my code for deleting, public boolean onContextItemSelected(MenuItem item) { super.onContextItemSelected(item); AdapterView.AdapterContextMenuInfo info = (AdapterView.AdapterContextMenuInfo) item .getMenuInfo(); int menuItemIndex = item.getItemId(); String[] menuItems = getResources().getStringArray(R.array.menu); String menuItemName = menuItems[menuItemIndex]; String listItemName = Customers[info.position]; if (item.getTitle().toString().equalsIgnoreCase("Delete")) { Toast.makeText( context, "Selected List item is: " + listItemName + "MenuItem is: " + menuItemName, Toast.LENGTH_LONG).show(); DB = context.openOrCreateDatabase("CustomerDetails.db", MODE_PRIVATE, null); try { int pos = info.position; pos = pos + 1; Log.d("", "customers[pos]: " + Customers[info.position]); Cursor c = DB .rawQuery( "Select customer_id,first_name,last_name from CustomerInfo", null); int rowCount = c.getCount(); DB.delete(Table_name, "customer_id" + "=" + String.valueOf(pos), null); DB.close(); Log.d("", "" + String.valueOf(pos)); Toast.makeText(context, "Deleted Customer", Toast.LENGTH_LONG) .show(); // Customers[info.position]=null; getCustomers(); } catch (Exception e) { Toast.makeText(context, "Delete unsuccessfull", Toast.LENGTH_LONG).show(); } } this is my logcat, 07-02 10:12:42.976: D/Cursor(1560): Database path: CustomerDetails.db 07-02 10:12:42.976: D/Cursor(1560): Table name : null 07-02 10:12:42.984: D/Cursor(1560): Database path: CustomerDetails.db 07-02 10:12:42.984: D/Cursor(1560): Table name : null Don't know the reason why data is not being deleted. Data exists in the table. This is the specification I have given for creating the table public static String customer_id="customer_id"; public static String site_id="site_id"; public static String last_name="last_name"; public static String first_name="first_name"; public static String phone_number="phone_number"; public static String address="address"; public static String city="city"; public static String state="state"; public static String zip="zip"; public static String email_address="email_address"; public static String custlat="custlat"; public static String custlng="custlng"; public static String Table_name="CustomerInfo"; final SQLiteDatabase DB = context.openOrCreateDatabase( "CustomerDetails.db", MODE_PRIVATE, null); final String CREATE_TABLE = "create table if not exists " + Table_name + " (" + customer_id + " integer primary key autoincrement, " + first_name + " text not null, " + last_name + " text not null, " + phone_number+ " integer not null, " + address+ " text not null, " + city+ " text not null, " + state+ " text not null, " + zip+ " integer not null, " + email_address+ " text not null, " + custlat+ " double, " + custlng+ " double " +" );"; DB.execSQL(CREATE_TABLE); DB.close(); Please correct my code. I am struggling from two days. Any help is appreciated!!

  • How to Force Graphics Options in PC Games with NVIDIA, AMD, or Intel Graphics

    - by Chris Hoffman
    PC games usually have built-in graphics options you can change. But you’re not limited to the options built into games — the graphics control panels bundled with graphics drivers allow you to tweak options from outside PC games. For example, these tools allow you to force-enabling antialiasing to make old games look better, even if they don’t normally support it. You can also reduce graphics quality to get more performance on slow hardware. If You Don’t See These Options If you don’t have the NVIDIA Control Panel, AMD Catalyst Control Center, or Intel Graphics and Media Control Panel installed, you may need to install the appropriate graphics driver package for your hardware from the hardware manufacturer’s website. The drivers provided via Windows Update don’t include additional software like the NVIDIA Control Panel or AMD Catalyst Control Center. Drivers provided via Windows Update are also more out of date. If you’re playing PC games, you’ll want to have the latest graphics drivers installed on your system. NVIDIA Control Panel The NVIDIA Control Panel allows you to change these options if your computer has NVIDIA graphics hardware. To launch it, right-click your desktop background and select NVIDIA Control Panel. You can also find this tool by performing a Start menu (or Start screen) search for NVIDIA Control Panel or by right-clicking the NVIDIA icon in your system tray and selecting Open NVIDIA Control Panel. To quickly set a system-wide preference, you could use the Adjust image settings with preview option. For example, if you have old hardware that struggles to play the games you want to play, you may want to select “Use my preference emphasizing” and move the slider all the way to “Performance.” This trades graphics quality for an increased frame rate. By default, the “Use the advanced 3D image settings” option is selected. You can select Manage 3D settings and change advanced settings for all programs on your computer or just for specific games. NVIDIA keeps a database of the optimal settings for various games, but you’re free to tweak individual settings here. Just mouse-over an option for an explanation of what it does. If you have a laptop with NVIDIA Optimus technology — that is, both NVIDIA and Intel graphics — this is the same place you can choose which applications will use the NVIDIA hardware and which will use the Intel hardware. AMD Catalyst Control Center AMD’s Catalyst Control Center allows you to change these options on AMD graphics hardware. To open it, right-click your desktop background and select Catalyst Control Center. You can also right-click the Catalyst icon in your system tray and select Catalyst Control Center or perform a Start menu (or Start screen) search for Catalyst Control Center. Click the Gaming category at the left side of the Catalyst Control Center window and select 3D Application Settings to access the graphics settings you can change. The System Settings tab allows you to configure these options globally, for all games. Mouse over any option to see an explanation of what it does. You can also set per-application 3D settings and tweak your settings on a per-game basis. Click the Add option and browse to a game’s .exe file to change its options. Intel Graphics and Media Control Panel Intel integrated graphics is nowhere near as powerful as dedicated graphics hardware from NVIDIA and AMD, but it’s improving and comes included with most computers. Intel doesn’t provide anywhere near as many options in its graphics control panel, but you can still tweak some common settings. To open the Intel graphics control panel, locate the Intel graphics icon in your system tray, right-click it, and select Graphics Properties. You can also right-click the desktop and select Graphics Properties. Select either Basic Mode or Advanced Mode. When the Intel Graphics and Media Control Panel appears, select the 3D option. You’ll be able to set your Performance or Quality setting by moving the slider around or click the Custom Settings check box and customize your Anisotropic Filtering and Vertical Sync preference. Different Intel graphics hardware may have different options here. We also wouldn’t be surprised to see more advanced options appear in the future if Intel is serious about competing in the PC graphics market, as they say they are. These options are primarily useful to PC gamers, so don’t worry about them — or bother downloading updated graphics drivers — if you’re not a PC gamer and don’t use any intensive 3D applications on your computer.
