  • Visual Studio - How to disable autoformat/correct while running macro?

    - by Sam
    When running a macro that changes the selected text, tags are automatically closed and the text formatted. How can I prevent that from happening? For example, wrapping text in a tag: DTE.ActiveDocument.Selection.Text = String.Format("<tag>{0}</tag>", DTE.ActiveDocument.Selection.Text) Ends up with two closing tags: <tag>Text</tag></tag> Even stranger, multiple lines fails: <li>One</li> <li>Two</li> <li>Three</li> An ends up as <ul> <li>One</li> <li>Two</li> <li>Three</li></li></ul> How can I prevent that? As can be seen by the last example, the formatting is wrong and there is an extra </li>

  • MySQL differences between to select queries

    - by bpmccain
    I have two mysql queries that return a column of phone numbers. I want am trying to end up with a list of phone numbers that are in one list, but not in the other. So the two queries I have are: SELECT phone FROM civicrm_phone phone LEFT JOIN civicrm_participant participant ON phone.contact_id = participant.contact_id WHERE phone.is_primary = 1 AND participant.id IS NULL and SELECT phone FROM civicrm_phone phone LEFT JOIN civicrm_participant participant ON phone.contact_id = participant.contact_id WHERE phone.is_primary = 1 AND participant.id IS NOT NULL And before anyone asks, the above two queries do not provide mutually exclusive results (based on using IS NULL and IS NOT NULL for the last WHERE statement), since we have related individuals in the database who use the same phone number, but do not necessarily all have a participant.id. Thanks for any help.

  • RAID options for a LAMP web server

    - by jetboy
    I'm due to set up a LAMP web server with four drives and a RAID controller to act as a web server. The drives are 146Gb SAS, and the machine has two quad core processors and 16Gb RAM. There will be very few write operations to the MySQL database, and I'll be using as much caching as possible to reduce disk I/O. Question is: Would I be better off splitting the drives into two RAID 1 arrays, splitting up sequential and random disk I/O, or would I get better overall performance putting them all in a single RAID 1+0 array?

  • NSWindow does not respond to keystroke command-s

    - by wackazong
    Hello, it may pre very simple, but cannot find it: I have three windows in three separate NIBs in my application. One is opened when a new document is opened, the other two can be opened from the program's window menu. The problem is: two windows (in them the one that is opened at the beginning) accepts the normal keystroke as for example command-s for save, and the other one does not and gives a warning sound instead. I cannot figure out the difference between the two windows or their controllers. I know it will have to do with the responder chain, but I am left clueless. Any ideas? Thanks, wackazong

  • Get size of UIView after applying CGAffineTransform

    - by Ican Zilb
    I was surprised not to find an answer to this question, maybe is something very simple I somehow overlook : How to get the real size of an UIView after I apply a CGAffineTransform to it? eg. my UIView has size 300 x 200, I apply a scaling transform let's say factor 2 both horizontal and vertical, so the UIView now takes 600 x 400 on the screen, but it's bounds and it's layer's bounds are still returning a size of 300 x 200 ... where do I find the real size of the UIView ?

  • Combinatorics, probability, dice

    - by TarGz
    A friend of mine asked: if I have two dice and I throw both of them, what is the most frequent sum (of the two dice' numbers)? I wrote a small script: from random import randrange d = dict((i, 0) for i in range(2, 13)) for i in xrange(100000): d[randrange(1, 7) + randrange(1, 7)] += 1 print d Which prints: 2: 2770, 3: 5547, 4: 8379, 5: 10972, 6: 13911, 7: 16610, 8: 14010, 9: 11138, 10: 8372, 11: 5545, 12: 2746 The question I have, why is 11 more frequent than 12? In both cases there is only one way (or two, if you count reverse too) how to get such sum (5 + 6, 6 + 6), so I expected the same probability..?

  • Drivers not installing and drives not being recognized

    - by jab818
    Dell optiplex 755 running win7-32 Two problems, not sure if they're related 1: Two drivers are missing when viewing device manager, PCI serial port and PCI Simple Communications Controller, I've searched dell's site, and the internet as a whole and have been wholly unable to find the drivers. 2: I'm unable to connect any external hard drives, but any flash drives plugged in will be recognized and accessible by the computer without issue. Any help would be appreciated.

  • What is the scope of xsl apply-imports?

    - by calavera.info
    My original idea about apply-imports was that if there are two templates which matches the same node, then using apply-imports in a template with higher priority runs the template with the lower priority. But I recently find out that it's important how are imports organized. Two cases interests me particularly. Will apply imports work on a template which is imported in imported file (nested import)? How about a "sibling import" (master file imports two files with templates matching the same nodes) It seems to me that this is not clearly described in specification. Could someone provide authoritative guidelines? EDIT: I can try those cases on my own, but there is always a danger that it will be implementation specific behavior.

  • finding a string of random characters (with possible errors) within a large string of random charact

    - by mike
    I am trying to search a large string w/o spaces for a smaller string of characters. using regex I can easily find perfect matches but I can't figure out how to find partial matches. by partial matches i mean one or two extra characters in the string or one or two characters that have been changed, or one of each. the first and last characters will always match though. this would be similar to a spell checker but there are no spaces and the strings dont contain actual words, just random hex digits. i figured a way to find the string if there are no extra characters using indexOf(string.charAt(0)) and indexOf(charAt(string.length()-1) and looping through the characters between the two indexes. but this can be problematic when dealing with randomized characters because of the possibility of finding the first and last characters at the correct spacing but none of the middle characters matching. i've been scratching my head for hours on this issue. any ideas?

  • Problem installing Cardbus/PCMCIA drivers (USB 2.0 2-port)

    - by Carl
    I obtained the drivers from the manufacturer for my HT-Link NEC USB 2.0 2-port Cardbus card. When I plugged in the card before I got the drivers, 3 new entries showed up in the Device Manager - two "NEC PCI to USB Open Host Controller" and one "Standard Enhanced PCI to USB Host controller." With the card plugged in, I uninstalled those two drivers. I then removed the card. I copied the new drivers to c:\windows\system32\drivers and the .inf file to c:\windows\inf. I also copied the drivers & inf to a new directory called c:\windows\drivers\ousb2. I reinserted the card. Windows automatically installed the same drivers as before. I selected 'update driver' on the "NEC PCI to USB..." entry and didn't see any other options. I then selected 'have disk' and pointed to c:\windows\drivers\ousb2 and got a message "The specified location does not contain information about your hardware." I then selected 'update driver' on the "Standard Enhanced PCI to USB...," and manually selected "USB 2.0 Enhanced Host Controller" (OWC 4/15/2003 2.1.3.1). Windows then automatically found a USB root hub, and I manually selected "USB 2.0 Root Hub Device" (OWC 4/15/2003 2.1.3.1). Now there are two sections in the Device Manager titled "Universal Serial Bus controllers." I plugged in my external USB hard disk adapter, and "USB Mass Storage Device" was added to the first set. Here's how it looks (w/drivers from the properties): [Universal Serial Bus controllers] Intel(R) 82801DB/DBM USB 2.0 Enhanced Host Controller - 24CD (6/1/2002 5.1.2600.0) Intel(R) 82801DB/DBM USB Universal Host Controller - 24C2 (7/1/2001 5.1.2600.5512) Intel(R) 82801DB/DBM USB Universal Host Controller - 24C4 (7/1/2001 5.1.2600.5512) Intel(R) 82801DB/DBM USB Universal Host Controller - 24C7 (7/1/2001 5.1.2600.5512) NEC PCI to USB Open Host Controller (7/1/2001 5.1.2600.5512) NEC PCI to USB Open Host Controller (7/1/2001 5.1.2600.5512) USB Mass Storage Device USB Root Hub (7/1/2001 5.1.2600.5512) (5 more USB Root Hubs - same driver) [Universal Serial Bus controllers] USB 2.0 Enhanced Host Controller (OWC 4/15/2003 2.1.3.1) USB 2.0 Root Hub Device (OWC 4/15/2003 2.1.3.1) When I unplug the card the two "NEC PCI to USB..." entries in the first set disappear, and the whole second set disappears. (I unplugged the hard disk adapter first...) The hard disk adapter still doesn't work in that Cardbus card with the new drivers. I don't think the above looks right - a second set of USB controllers listed in the Device Manager, and the NEC entries still in the first set, and the the USB mass storage device still in the first set. Any help appreciated. (Windows XP PRO SP3 w/all current updates.)

  • WinSCP equivalent for Linux/Ubuntu

    - by Shashank
    I'm shifting most of my projects to a Linux machine, and one of the things that I miss is WinSCP. I've found other answers saying that nautilus, FileZilla etc. can be used for SFTP, but something that I loved about WinSCP was that it has two panes (FileZilla's got that) and I could start synchronization from any directory. Unison or Rsync could work, but I'd have to create a folder pair every time I want to sync two folders. Is there an SFTP client for Linux that has a two-paned view and allows ad-hoc synchronization? Thanks!

  • iPhone to iPhone communication

    - by Dan
    Hi, I have been looking into communication methods between two iPhone devices and as I understand it there are two main methods to do this: Bluetooth and WiFi. However I wanted to know if anyone knows of any other way of sharing information between two iPhones? If I were in an area with no WiFi or mobile signal, and couldn't use Bluetooth for whatever reason, is there anything that could be done to broadcast data from one iPhone to another? I'm sure its a bit of a silly question, but if you don't ask, you don't get; and if someone knows of anything I might be able to look into with regards to this, I would be very appreciative. Thanks, Dan

  • Second WAN/LAN in office, want to share printers between them

    - by ndavis
    My business is growing so I've decided to purchase a second DSL line, to separate two departments to allow for more bandwidth usage. Previously I had a network printer that served both departments. With the addition of the second DSL line, I'm potentially going to have two separate LANs. How can I set it up so that the new LAN still has access to the Network Printer, but ensure that they are still using the new DSL line?

  • How to structure a Genetic Algorithm class hierarchy?

    - by MahlerFive
    I'm doing some work with Genetic Algorithms and want to write my own GA classes. Since a GA can have different ways of doing selection, mutation, cross-over, generating an initial population, calculating fitness, and terminating the algorithm, I need a way to plug in different combinations of these. My initial approach was to have an abstract class that had all of these methods defined as pure virtual, and any concrete class would have to implement them. If I want to try out two GAs that are the same but with different cross-over methods for example, I would have to make an abstract class that inherits from GeneticAlgorithm and implements all the methods except the cross-over method, then two concrete classes that inherit from this class and only implement the cross-over method. The downside to this is that every time I want to swap out a method or two to try out something new I have to make one or more new classes. Is there another approach that might apply better to this problem?

  • Does a router have a receiving range?

    - by Aadit M Shah
    So my dad bought a TP-Link router (Model No. TL-WA7510N) which apparently has a transmitting range of 1km; and he believes that it also has a receiving range of 1km. So he's arguing with me that the router (which is a trans-receiver) can communicate with any device in the range of 1km whether or not that device has a transmitting range of 1km. To put it graphically: +----+ 1km +----+ | |------------------------------------------------->| | | TR | | TR | | | <----| | +----+ 100m+----+ So here's the problem: The two devices are 1km apart. The first device has a transmitting range of 1km. The second device only has a transmitting range of 100m. According to my dad the two devices can talk to each other. He says that the first device has a transmitting and a receiving range of 1km which means that it can both send data to devices 1km away and receive data from devices 1km away. To me this makes no sense. If the second device can only send data to devices 100m away then how can the first device catch the transmission? He further argues that for bidirectional communication both the sender and the reciver should have overlapping areas of transmission: According to him if two devices have an overlapping area of transmission then they can communicate. Here neither device has enough transmission power to reach the other. However they have enough receiving power to capture the transmission. Obviously this makes absolutely no sense to me. How can a device sense a transmission which hasn't even reached it yet and go out, capture it and bring it back it. To me a trans-receiver only has a transmission power. It has zero receiving power. Hence for two devices to be able to communicate bidirectionally, the diagram should look like: Hence, from my point of view, both the devices should have a transmission range far enough to reach the other for bidirectional communication to be possible; but no matter how much I try to explain to my dad he adamantly disagrees. So, to put an end to this debate once and for all, who is correct? Is there even such a thing as a receiving range? Can a device fetch a transmission that would otherwise never reach it? I would like a canonical answer on this.

  • Alternative to setpoint that allows key configuration profiles for multiple mice?

    - by Razor Storm
    I have 2 mice: Logitech MX Revolution and Razer DeathAdder. I use my mx revolution for browsing internet (I set up a lot of hotkeys on all my buttons to make browsing really convenient) and the deathadder for gaming (the mouse is a lot more accurate and smooth). The problem is that by having two mice, setpoint randomly forgets its settings once in a while (I'm assuming due to getting confused why theres two input devices), and I constantly have to restart setpoint (every few minutes) to get it to rerecognize that the

  • Setting up a wireless connection b'ween 2 clients

    - by shadeMe
    I've got a DLINK router connected to my ADSL modem that forms the hub of my home network. I've two clients - A desktop with an onboard wireless adaptor and a laptop that's outfitted with the same. The former runs Windows 7 x64, the latter Windows XP x86. I'd like to setup a wireless connection between the two that would allow me play games over to and to a lesser extent, transfer and stream data. How would I go about doing it ?

  • SSH asking for password for one user and not another

    - by Ocasta Eshu
    I have two users on the same machine and am attempting to set up SSH for user#2. SSH was still asking for a password for the second user so I copied the .rsa file from user#1 to user#2. although they have identical files and permissions and although no password is asked of user#1, SSH still asks for a password from user#2. What could cause two users on the same machine with identical .rsa files to have different responses from SSH?

  • Networking switch setup

    - by Crash893
    I have two 48 port gigabit netgear switches with 2 SFP ports each (i also have two Mini-GBIC copper transceiver modules) Is it best to set the ports up by using the built in ports (ie plug port 1 of switchB into port 48 of switchA and port1 of switchA into the router) or is there an advantage to using the mini-gbic? (lets call the sfp ports 49 and 50) router - port 49 on switchA, port 50 switchA - port 49 SwitchB

  • .Net Xml Serialize - XSD Definition for Multiple Namespaces

    - by MattH
    The following XML was generated by serializing .Net objects: <?xml version="1.0" encoding="utf-8"?> <Request xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://EPS.WebServices/WebServiceSchema" > <Method xmlns="http://EPS.Library/RequestSchema">PackPlacementUpdate</Method> <Type xmlns="http://EPS.Library/RequestSchema">PackPlacementUpdate</Type> </Request> I am using XSD to generate a schema. However, (I think) because there are multiple namespaces two different schema files get generated. We will be providing the XSD file externally and I'm concerned that two files will cause confusion. Without changing the namespace of the .Net classes, is there is a way I can create a single XSD schema file and not two? Thanks.
