  • Is it better to use a crowded 2.4GHz Wi-Fi channel 1, 6, 11 or "unused" 3, 4, 8, or 9?

    - by Luke
    I understand that 2.4GHz Wi-Fi channels overlap, and that the only non-overlapping channels in the US are 1, 6, and 11. Generally, my signal strength on channels 1, 6, and 11 are much stronger than my neighbors' on the same channel. However, several of the channels may have 4 or 5 others on that same channel. In this scenario, is it better to use 3, 4, 8, or 9? Or is it better to use the crowded channels 1, 6, and 11? As a secondary question, does it even matter that my signal strength is much higher than theirs? Related: Why use wifi channels other than 1, 6 or 11?

  • Remotely running batches on a Windows PC

    - by Eduardo León
    I want to remotely control my home desktop PC (running Windows 7 Professional), mainly to perform the following tasks: Downloading email attachments, and sending emails with attachments Running UI-less programs whose only inputs are files and whose only outputs are files So far, the only solution I have found is to use Remote Desktop to connect to my PC, but this is very slow and inefficient, especially when there is no fast Internet connection available other than my cell phone's. I would like to be able to send batch commands to my PC, like: Download an email attachment Use it as input for an UI-less program Save the program's output to a file Send that file to myself as an email attachment Is this possible? How could I do it?

  • Turn on PC power remotely through the Internet?

    - by W.N.
    I use SVN for my work at home and office, but I usually forget to commit the changes before shutdown. Therefore, I wish I could turn on my home/office PC at office/home. I already have TeamViewer installed on both PCs, so it will be okay as soon as the power is turned on. I have read many articles about this, I found both my PC and office computers support Wake-on-LAN. However, I don't know much about other config. And I need to turn on my computers through the Internet, not on LAN. My office Internet connection has static IP, however, my home Internet connection has dynamic IP, it changes as soon as I reset the modem, but it is not a big problem, I rarely turn the Internet modem off. And I don't have privilege to config office Internet connection, but I have Administration privilege on both PCs. Please give me details steps to turn on my office PC from home, and turn on my home PC from office.

  • SQL UPDATE based on condition

    - by LtDan
    We need to update a table with the users id (NBK). The table with NBK also has the user status (0 - 1) and only one user will have 1 at a time. The challenage is to #1 capture the active user #2 update the other table with the user NBK. I hope the code below just has a simple syntex error that I cannot find? Dim nb As String Dim NBK As String nb = [Employees]![NBK] & "' WHERE " nb = nb & " " & [Employees]![Status] = '1' NBK = " Update tbl_DateTracking SET NBK = " NBK = NBK & "'" & nb & "' WHERE " NBK = NBK & "CaseId = '" & CaseId & "' AND OCC_Scenario = '" & OCC_Scenario & "' ;" DoCmd.RunSQL nb DoCmd.RunSQL NBK

  • Using cssh with an ssh clone

    - by decimus phostle
    Just had a quick question about using ClusterSSH(cssh) with a homegrown ssh-like/ssh-clone application which we use internally to connect to remote machines. I tried using the ssh = /path/to/ssh_clone override in $HOME/.csshrc or /etc/csshrc (or even passing it via -C). Unfortunately running cssh with debug shows that it is still trying to connect to the remote machines as ssh -l user machine_ip instead of ssh_clone -l user machine_ip. Any thoughts/suggestions on how to work around this would be greatly appreciated. TIA. Edit: Version info $ cssh -v Version: 4.01_02

  • Exchange 2010 UR3 - customizing OWA logon page

    - by STGdb
    I have an Exchange 2010 UR3 deployment that I need to customize the OWA logon page for. I've created a new LGNTOPL.GIF file to replace the existing one in the folder: “C:\Program Files\Microsoft\Exchange Server\V14\ClientAccess\Owa\14.3.158.1\themes\resources” When I bring up OWA, I still get the original “Outlook Web App” logo. I’ve searched and found a couple of other instances of LGNTOPL.GIF in the directories: “C:\Program Files\Microsoft\Exchange Server\V14\ClientAccess\Owa\14.3.123.3\themes\resources” “C:\Program Files\Microsoft\Exchange Server\V14\ClientAccess\Owa\14.3.146.0\themes\resources” “C:\Program Files\Microsoft\Exchange Server\V14\ClientAccess\Owa\Current\themes\resources” I’ve replaced the LGNTOPL.GIF file in each of the above directories but got the same results. I’ve tried clearing my browser cache and even using multiple browsers from multiple PC’s but the same results. I’ve even tried making my GIF file the same pixel size as the original LGNTOPL.GIF logo but still the same results. I’ve tried restarting IIS on the CAS server and restarting the server but same results. Has something changed with Exchange 2010 UR3 when trying to customize OWA? I don't see anything documented about any change to OWA customization. Thanks

  • Connect from Mac OS X to Windows 7 Desktop

    - by jrn
    I am trying to connect from my MacBook to my Windows 7 machine within my own network - if it will work from outside my network that's a plus but no need to have. My Windows 7 machine is freshly installed with Windows 7 Home Premium. It runs the built-in firewall with no settings changed so far as well as Microsoft Security Essentials. So far I tried CoRD and Microsofts Remote Desktop Connections to connect from my Mac to my Windows machine without any success. I did try and disabled the firewall on my Windows machine but could not connect either. The reason I did this was to check wether there is a Windows firewall setting preventing me from connecting. On top of that I manually started the Remote Desktop Services and Remote Desktop Configuration within services.msc. Is there anything else I have to enable for a remote desktop connection? Could there be any router setting I have to tweak? Since I do not want to connect from outside my own network I thought I don't have to do any port forwarding. The error messages I retrieve are all connection timeouts. I can however ping the hostname and/or IP address. Any help would be greatly appreciated. Thanks a lot, jrn

  • Outlook or OWA: How can I convert an e-mail message to a draft?

    - by Beaming Mel-Bin
    There's an option in Thunderbird called Edit as new... which converts a message to a draft. I am looking for something similar in Exchange. Reasoning: We migrated old e-mail of a user from an IMAP server to Exchange. The user had many drafts saved. According to exchange though, the messages are not drafts anymore. My hunch is that, if we find a similar procedure as Thunderbird's Edit as new..., that should do the trick.

  • Android - Emulator internet access

    Hi, I've been using this method to gain access to internet from my Android emulator emulator -http-proxy < -avd < It works but is that the best way to do it? It just doesn't feel right that I need to open the emulator from command line and can't just do it from Eclipse or something. Can't seem to find an internet option on the "AVD Manager" either. Thanks, Tee

  • Impersonation - Access is denied

    - by krisg
    I am having trouble using impersonation to delete a PerformanceCounterCategory from an MVC website. I have a static class and when the application starts it checks whether or not a PerformanceCounterCategory exists, and if it contains the correct counters. If not, it deletes the category and creates it again with the required counters. It works fine when running under the built in webserver Cassini, but when i try run it through IIS7 (Vista) i get the following error: Access is denied Description: An unhandled exception occurred during the execution of the current web request.

  • Access custom attribute on method from Castle Windsor interceptor

    I am trying to access a custom attribute applied to a method within a castle interceptor, e.g.: [MyCustomAttribute(SomeParam = "attributeValue")] public virtual MyEntity Entity { get; set; } using the following code: internal class MyInterceptor : IInterceptor { public void Intercept(IInvocation invocation) { if (invocation.Method.GetCustomAttributes(typeof(MyCustomAttribute), true) != null) { //Do something } } } The interceptor is firing OK when the method is called but this code does not return the custom attribute. How can I achieve this?

  • How to access SVG elements with Javascript

  • Access Violation Using memcpy or Assignment to an Array in a Struct

    - by Synetech inc.
    Hi, I wrote a program last night that worked just fine but when I refactored it today to make it more extensible, I ended up with a problem. The original version had a hard-coded array of bytes. After some processing, some bytes were written into the array and then some more processing was done. To avoid hard-coding the pattern, I put the array in a structure so that I could add some related data and create an array of them. However now, I cannot write to the array in the structure. Here’s a pseudo-code example: main() { char pattern[]="\x32\x33\x12\x13\xba\xbb"; PrintData(pattern); pattern[2]='\x65'; PrintData(pattern); } That one works but this one does not: struct ENTRY { char* pattern; int somenum; }; main() { ENTRY Entries[] = { {"\x32\x33\x12\x13\xba\xbb\x9a\xbc", 44} , {"\x12\x34\x56\x78", 555} }; PrintData(Entries[0].pattern); Entries[0].pattern[2]='\x65'; //0xC0000005 exception!!! :( PrintData(Entries[0].pattern); } The second version causes an access violation exception on the assignment. I’m sure it’s because the second version allocates memory differently, but I’m starting to get a headache trying to figure out what’s what or how to get fix this. (I’m currently working around it by dynamically allocating a buffer of the same size as the pattern array, copying the pattern to the new buffer, making the changes to the buffer, using the buffer in the place of the pattern array, and then trying to remember to free the—temporary—buffer.) (Specifically, the original version cast the pattern array—+offset—to a DWORD* and assigned a DWORD constant to it to overwrite the four target bytes. The new version cannot do that since the length of the source is unknown—may not be four bytes—so it uses memcpy instead. I’ve checked and re-checked and have made sure that the pointers to memcpy are correct, but I still get an access violation. I use memcpy instead of str(n)cpy because I am using plain chars (as an array of bytes), not Unicode chars and ignoring the null-terminator. Using an assignment as above causes the same problem.) Any ideas? Thanks a lot.

  • UISplitView: how to access instance?

    - by chpwn
    I have a navigation controller in my left portion of my split view, and in the right portion. But sometimes, for example when an item is tapped, my left side must manually set the view controller on the right side. Where is the best place to store the split view controller instance? Pass it around to each view controller on the left side, like I do with the navigation controller? Store it in my App Delegate and then access it via a property with [[UIApplication sharedApplication] delegate].splitView?
