  • WPA2 authentication fails on Ubuntu 12.04 using Rosewill RNX-N1

    - by user94156
    Decided to reduce the clutter in the house and replace a wired connection with a wireless one on my wife's system using USB network device Rosewill RNX-X1. I can see and connect to unprotected network, but WPA2 authentication repeatedly fails. RNX-X1 works on other systems (including TV); also have 2 of 'em and tried each. Worth noting that I recently switched from Comcast to CenturyLink and so switched routers. The system connected successfully to previous router (Linksys EA4500) using WPA2. Would think it is the router (Actiontec C1000A) but all other devices (TV, iPad, Windows, Blackberry, and Squeezebox) connect ok. Would appreciate some diagnostic guidance and insight (phrased for a newbie!)

  • Disable alt + tab moving windows by itself

    - by Lie Ryan
    Whenever I press Alt + Tab , Unity moves the window I'm switching to so that the whole window is inside the screen. This behavior is excruciatingly annoying because I often move a window (usually text editors) partially outside the current screen so I can view another window below it (usually a browser). Every time I Alt + Tab back to the text editor, I'm getting an unnecessary virtual screen switch, and Unity is rearranging the windows behind my back. For instance, here is a browser and text editor on Virtual Screen 1 (top left), note that the text editor is partially outside the current screen: Then I Alt-Tab to the browser (or clicked on it): Next, I Alt + Tab again to get back to the text editor, but Alt-Tab switched me to Virtual Screen 4 (bottom right) because a larger percentage of the text editor window is on virtual screen 4 than in virtual screen 1; and the browser is no longer in the screen. Also note that the text editor window moves from being on the bottom-right to the top-left, which is very disorienting as I can no longer keep track of where any of my windows are since they all keep moving around by themselves.. How do I disable this behavior? I don't want to have any virtual screen switch when Alt + Tab , especially since Alt + Tab does not list windows that is completely not in the current virtual screen anyway.

  • Where we should put validation for domain model

    - by adisembiring
    I still looking best practice for domain model validation. Is that good to put the validation in constructor of domain model ? my domain model validation example as follows: public class Order { private readonly List<OrderLine> _lineItems; public virtual Customer Customer { get; private set; } public virtual DateTime OrderDate { get; private set; } public virtual decimal OrderTotal { get; private set; } public Order (Customer customer) { if (customer == null) throw new ArgumentException("Customer name must be defined"); Customer = customer; OrderDate = DateTime.Now; _lineItems = new List<LineItem>(); } public void AddOderLine //.... public IEnumerable<OrderLine> AddOderLine { get {return _lineItems;} } } public class OrderLine { public virtual Order Order { get; set; } public virtual Product Product { get; set; } public virtual int Quantity { get; set; } public virtual decimal UnitPrice { get; set; } public OrderLine(Order order, int quantity, Product product) { if (order == null) throw new ArgumentException("Order name must be defined"); if (quantity <= 0) throw new ArgumentException("Quantity must be greater than zero"); if (product == null) throw new ArgumentException("Product name must be defined"); Order = order; Quantity = quantity; Product = product; } } Thanks for all of your suggestion.

  • Understanding 400 Bad Request Exception

    - by imran_ku07
        Introduction:          Why I am getting this exception? What is the cause of this error. Developers are always curious to know the root cause of an exception, even though they found the solution from elsewhere. So what is the reason of this exception (400 Bad Request).The answer is security. Security is an important feature for any application. ASP.NET try to his best to give you more secure application environment as possible. One important security feature is related to URLs. Because there are various ways a hacker can try to access server resource. Therefore it is important to make your application as secure as possible. Fortunately, ASP.NET provides this security by throwing an exception of Bad Request whenever he feels. In this Article I am try to present when ASP.NET feels to throw this exception. You will also see some new ASP.NET 4 features which gives developers some control on this situation.   Description:   http.sys Restrictions:           It is interesting to note that after deploying your application on windows server that runs IIS 6 or higher, the first receptionist of HTTP request is the kernel mode HTTP driver: http.sys. Therefore for completing your request successfully you need to present your validity to http.sys and must pass the http.sys restriction.           Every http request URL must not contain any character from ASCII range of 0x00 to 0x1F, because they are not printable. These characters are invalid because these are invalid URL characters as defined in RFC 2396 of the IETF. But a question may arise that how it is possible to send unprintable character. The answer is that when you send your request from your application in binary format.           Another restriction is on the size of the request. A request containg protocal, server name, headers, query string information and individual headers sent along with the request must not exceed 16KB. Also individual header should not exceed 16KB.           Any individual path segment (the portion of the URL that does not include protocol, server name, and query string, for example, http://a/b/c?d=e,  here the b and c are individual path) must not contain more than 260 characters. Also http.sys disallows URLs that have more than 255 path segments.           If any of the above rules are not follow then you will get 400 Bad Request Exception. The reason for this restriction is due to hack attacks against web servers involve encoding the URL with different character representations.           You can change the default behavior enforced by http.sys using some Registry switches present at HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\HTTP\Parameters    ASP.NET Restrictions:           After passing the restrictions enforced by the kernel mode http.sys then the request is handed off to IIS and then to ASP.NET engine and then again request has to pass some restriction from ASP.NET in order to complete it successfully.           ASP.NET only allows URL path lengths to 260 characters(only paths, for example http://a/b/c/d, here path is from a to d). This means that if you have long paths containing 261 characters then you will get the Bad Request exception. This is due to NTFS file-path limit.           Another restriction is that which characters can be used in URL path portion.You can use any characters except some characters because they are called invalid characters in path. Here are some of these invalid character in the path portion of a URL, <,>,*,%,&,:,\,?. For confirming this just right click on your Solution Explorer and Add New Folder and name this File to any of the above character, you will get the message. Files or folders cannot be empty strings nor they contain only '.' or have any of the following characters.....            For checking the above situation i have created a Web Application and put Default.aspx inside A%A folder (created from windows explorer), then navigate to, http://localhost:1234/A%25A/Default.aspx, what i get response from server is the Bad Request exception. The reason is that %25 is the % character which is invalid URL path character in ASP.NET. However you can use these characters in query string.           The reason for these restrictions are due to security, for example with the help of % you can double encode the URL path portion and : is used to get some specific resource from server.   New ASP.NET 4 Features:           It is worth to discuss the new ASP.NET 4 features that provides some control in the hand of developer. Previously we are restricted to 260 characters path length and restricted to not use some of characters, means these characters cannot become the part of the URL path segment.           You can configure maxRequestPathLength and maxQueryStringLength to allow longer or shorter paths and query strings. You can also customize set of invalid character using requestPathInvalidChars, under httpruntime element. This may be the good news for someone who needs to use some above character in their application which was invalid in previous versions. You can find further detail about new ASP.NET features about URL at here           Note that the above new ASP.NET settings will not effect http.sys. This means that you have pass the restriction of http.sys before ASP.NET ever come in to the action. Note also that previous restriction of http.sys is applied on individual path and maxRequestPathLength is applied on the complete path (the portion of the URL that does not include protocol, server name, and query string). For example, if URL is http://a/b/c/d?e=f, then maxRequestPathLength will takes, a/b/c/d, into account while http.sys will take a, b, c individually.   Summary:           Hopefully this will helps you to know how some of initial security features comes in to play, but i also recommend that you should read (at least first chapter called Initial Phases of a Web Request of) Professional ASP.NET 2.0 Security, Membership, and Role Management by Stefan Schackow. This is really a nice book.

  • Multiple IPs on firewall, are these virtual interfaces or what?

    - by Jakobud
    We have 5 static IP addresses from our ISP: XXX.XXX.XXX.180 XXX.XXX.XXX.181 XXX.XXX.XXX.182 XXX.XXX.XXX.183 XXX.XXX.XXX.184 On our firewall box, the NIC that is connected to our cable modem, appears to have all 5 IP addresses set on it. A previous IT guy set this thing up, and I'm not sure exactly what he did. Are these virtual interfaces on this NIC or what? Here is my ip addr output for that NIC: rwd0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether XX:XX:XX:XX:XX:XX brd ff:ff:ff:ff:ff:ff inet XXX.XXX.XXX.180/24 brd XXX.XXX.XXX.186 scope global rwd0 inet XXX.XXX.XXX.181/29 brd XXX.XXX.XXX.186 scope global rwd0:FWB9 inet XXX.XXX.XXX.182/29 brd XXX.XXX.XXX.186 scope global secondary rwd0:FWB10 inet XXX.XXX.XXX.183/29 brd XXX.XXX.XXX.186 scope global secondary rwd0:FWB11 inet XXX.XXX.XXX.184/29 brd XXX.XXX.XXX.186 scope global secondary rwd0:FWB12 inet6 fe80::250:8bff:fe61:5734/64 scope link valid_lft forever preferred_lft forever I'm a bit new to firewalls and networking so I'm just trying to figure out what he had going on here. I know he used Firewall Builder to configure the iptables rules, maybe that has something to do with the "FWB" I see in those names? So my questions are: What is going on here? Virtual Interfaces? Or something else? If we want to put in a second firewall in parallel with this firewall but we only want it to handle traffic to XXX.XXX.XXX.182, how do we get rid of the static XXX.XXX.XXX.182 address on this existing firewall box?

  • sudoer scheme for another web developer that retains my future control of a virtual server?

    - by Tchalvak
    Background: Virtual Private Server I have a virtual private server that I'm looking to host multiple websites on, and provide access to another web developer. I don't care about putting too many constraints on him, though I wouldn't mind isolating the site that he'll be developing from other sites on the server that I will develop. The problem: retain control Mainly what I want is to make sure that I retain control over the server in the future. I want to reserve the ability to create/promote/demote and other administrative functions that don't deal with web software. If I make him an admin, he can sudo su - and become root and remove root control from me, for example. I need him not to be able to: take away other admin permissions change the root password have control over other security/administrative functions I would like him to still be able to: install software (through apt-get) restart apache access mysql configure mysql/apache reboot edit web development configuration type files in /etc/ Other Standard Setups would be happily considered I've never really set up a good sudoers file, so simple example setups would be very useful, even if they're only somewhat similar to the settings that I'm hoping for above. Edit: I have not yet finalized permissions, standard, useful sudo setups are certainly an option, the lists above are more what I'm hoping I can do, I don't know that that setup can be done.

  • What is the alternative of Apache's global Alias in IIS instead of adding a Virtual Directory to every single sites one by one?

    - by Sk8erPeter
    In Apache, there's a way I can make phpMyAdmin available globally to all VirtualHosts I set up. In Apache, it looks like this: <IfModule mod_alias.c> Alias /phpmyadmin "c:/AppServ/www/phpMyAdmin" </IfModule> This way I reach phpmyadmin with prepending /phpmyadmin to all my domain names, and I can see phpmyadmin's initial page. (So for example it works for all my domains like this: http://example_1.com/phpmyadmin, http://example_2.com/phpmyadmin, http://example_3.com/phpmyadmin also does work). In IIS, there's an "Add Virtual Directory..." option when right clicking on a given site. Here I can set up e.g. phpMyAdmin's path to be reached with prepending /phpmyadmin to the given domain (e.g. http://example_1.com/phpmyadmin), but isn't there a "global" setting similar to Apache's Alias? Or do I have to add a virtual directory to every given sites one by one? I'm just curious, it's not a hard work to do it, but I'm interested in it if there exists another method to do it. Thanks in advance!

  • vSphere education - What are the downsides of configuring virtual machines with *too* much RAM?

    - by ewwhite
    VMware memory management seems to be a tricky balancing act. With cluster RAM, Resource Pools, VMware's management techniques (TPS, ballooning, host swapping), in-guest RAM utilization, swapping, reservations, shares and limits, there are a lot of variables. I'm in a situation where clients are using dedicated vSphere cluster resources. However, they are configuring the virtual machines as though they were on physical hardware. In turn, this means a standard VM build may have 4 vCPUs and 16GB or more of RAM. I come from the school of starting small (1 vCPU, minimal RAM), checking real-world use and adjusting up as necessary. Some examples from a "problem" cluster. Resource pool summary - Looks almost 4:1 overcommitted. Note the high amount of ballooned RAM. Resource allocation - The Worst Case Allocation column shows that these VMs would have access to less than 50% of their configured RAM under constrained conditions. The real-time memory utilization graph of the top VM in the listing above. 4 vCPU and 64GB RAM allocated. It averages under 9GB use. Summary of the same VM What are the downsides of overcommitting and overconfiguring resources (specifically RAM) in vSphere environments? Assuming that the VMs can run in less RAM, is it fair to say that there's overhead to configuring virtual machines with more RAM than they need? What is the counter-argument to: "if a VM has 16GB of RAM allocated, but only uses 4GB, what's the problem??"? E.g. do customers need to be educated? What specific metric should be used to meter RAM usage. Tracking the peaks of "Active" versus time?

  • How to backup virtual machines on a standalone ESXi host?

    - by Massimo
    Standalone ESXi (4.1) host without any vCenter Server. How to backup virtual machines as quickly and storage-friendly as possible? I know I can access the ESXi console and use the standard Unix cp command, but this has the downfall of copying the whole VMDK files, not only their actually used space; so, for a 30-GB VMDK of which only 1 GB is used, the backup would take 30 full GBs of space, and time accordingly. And yes, I know about thin-provisioned virtual disks, but they tend to behave very badly when physically copied, and/or to blow up to their full provisioned size; also, they are not recommended for actual VM performance. It is ok for me to shut down the VMs before backing them up (i.e. I don't need "live" backups); but I need a way to copy them around efficiently; and yes, a way to automate shutdown/startup when taking a backup would also help. I only have ESXi; no Service Console, no vCenter Server... what's the best way to handle this task? Also, what about restores?

  • How to setup a virtual host in Ubuntu running on Amazon EC2 instance?

    - by Rade
    I have an app that's accessible via 1.2.3.4/myapp. The app is installed in /var/www/myapp. I've set up a subdomain(apps.mydomain.com) that points to 1.2.3.4. I want the server to point to var/www/myapp if I type apps.mydomain.com/myapp, how do I do that? I have experience creating virtual hosts(lots of them) locally but I'm lost because it's now in production and it's a little different. Here's my virtual host config: <VirtualHost *:80> ServerAdmin webmaster@localhost ServerName apps.mydomain.com/myapp DocumentRoot /var/www/myapp/public <Directory /> Options FollowSymLinks AllowOverride All </Directory> <Directory /var/www/> Options Indexes FollowSymLinks MultiViews AllowOverride All Order allow,deny allow from all </Directory> ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/ <Directory "/usr/lib/cgi-bin"> AllowOverride All Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch Order allow,deny Allow from all </Directory> ErrorLog ${APACHE_LOG_DIR}/error.log # Possible values include: debug, info, notice, warn, error, crit, # alert, emerg. LogLevel warn CustomLog ${APACHE_LOG_DIR}/access.log combined </VirtualHost> Any idea why I still see the files instead of pointing me to the document root? Just in case someone might ask, the app is based on Laravel 4 framework. It's really bad right now because anyone can access the files from the browser.

I wish to build a query based on their id fields. This code @Override public List<Organization> findByOrgTypesCountryAndState(Set<String> organizationTypes, String countryId, String stateId) { CriteriaBuilder builder = entityManager.getCriteriaBuilder(); CriteriaQuery<Organization> criteria = builder.createQuery(Organization.class); Root<Organization> org = criteria.from(Organization.class); criteria.select(org).where(builder.and(org.get("organizationType.id").in(organizationTypes), builder.equal(org.get("state.id"), stateId), builder.equal(org.get("country.id"), countryId))); return entityManager.createQuery(criteria).getResultList(); } is throwing the exception below.

  • Find only physical network adapters with WMI Win32_NetworkAdapter class

    - by Mladen Prajdic
    WMI is Windows Management Instrumentation infrastructure for managing data and machines. We can access it by using WQL (WMI querying language or SQL for WMI). One thing to remember from the WQL link is that it doesn't support ORDER BY. This means that when you do SELECT * FROM wmiObject, the returned order of the objects is not guaranteed. It can return adapters in different order based on logged-in user, permissions of that user, etc… This is not documented anywhere that I've looked and is derived just from my observations. To get network adapters we have to query the Win32_NetworkAdapter class. This returns us all network adapters that windows detect, real and virtual ones, however it only supplies IPv4 data. I've tried various methods of combining properties that are common on all systems since Windows XP. The first thing to do to remove all virtual adapters (like tunneling, WAN miniports, etc…) created by Microsoft. We do this by adding WHERE Manufacturer!='Microsoft' to our WMI query. This greatly narrows the number of adapters we have to work with. Just on my machine it went from 20 adapters to 5. What was left were one real physical Realtek LAN adapter, 2 virtual adapters installed by VMware and 2 virtual adapters installed by VirtualBox. If you read the Win32_NetworkAdapter help page you'd notice that there's an AdapterType that enumerates various adapter types like LAN or Wireless and AdapterTypeID that gives you the same information as AdapterType only in integer form. The dirty little secret is that these 2 properties don't work. They are both hardcoded, AdapterTypeID to "0" and AdapterType to "Ethernet 802.3". The only exceptions I've seen so far are adapters that have no values at all for the two properties, "RAS Async Adapter" that has values of AdapterType = "Wide Area Network" and AdapterTypeID = "3" and various tunneling adapters that have values of AdapterType = "Tunnel" and AdapterTypeID = "15". In the help docs there isn't even a value for 15. So this property was of no help. Next property to give hope is NetConnectionId. This is the name of the network connection as it appears in the Control Panel -> Network Connections. Problem is this value is also localized into various languages and can have different names for different connection. So both of these properties don't help and we haven't even started talking about eliminating virtual adapters. Same as the previous one this property was also of no help. Next two properties I checked were ConfigManagerErrorCode and NetConnectionStatus in hopes of finding disabled and disconnected adapters. If an adapter is enabled but disconnected the ConfigManagerErrorCode = 0 with different NetConnectionStatus. If the adapter is disabled it reports ConfigManagerErrorCode = 22. This looked like a win by using (ConfigManagerErrorCode=0 or ConfigManagerErrorCode=22) in our condition. This way we get enabled (connected and disconnected adapters). Problem with all of the above properties is that none of them filter out the virtual adapters installed by virtualization software like VMware and VirtualBox. The last property to give hope is PNPDeviceID. There's an interesting observation about physical and virtual adapters with this property. Every virtual adapter PNPDeviceID starts with "ROOT\". Even VMware and VirtualBox ones. There were some really, really old physical adapters that had PNPDeviceID starting with "ROOT\" but those were in pre win XP era AFAIK. Since my minimum system to check was Windows XP SP2 I didn't have to worry about those. The only virtual adapter I've seen to not have PNPDeviceID start with "ROOT\" is the RAS Async Adapter for Wide Area Network. But because it is made by Microsoft we've eliminated it with the first condition for the manufacturer. Using the PNPDeviceID has so far proven to be really effective and I've tested it on over 20 different computers of various configurations from Windows XP laptops with wireless and bluetooth cards to virtualized Windows 2008 R2 servers. So far it always worked as expected. I will appreciate you letting me know if you find a configuration where it doesn't work. Let's see some C# code how to do this: ManagementObjectSearcher mos = null;// WHERE Manufacturer!='Microsoft' removes all of the // Microsoft provided virtual adapters like tunneling, miniports, and Wide Area Network adapters.mos = new ManagementObjectSearcher(@"SELECT * FROM Win32_NetworkAdapter WHERE Manufacturer != 'Microsoft'");// Trying the ConfigManagerErrorCode and NetConnectionStatus variations // proved to still not be enough and it returns adapters installed by // the virtualization software like VMWare and VirtualBox// ConfigManagerErrorCode = 0 -> Device is working properly. This covers enabled and/or disconnected devices// ConfigManagerErrorCode = 22 AND NetConnectionStatus = 0 -> Device is disabled and Disconnected. // Some virtual devices report ConfigManagerErrorCode = 22 (disabled) and some other NetConnectionStatus than 0mos = new ManagementObjectSearcher(@"SELECT * FROM Win32_NetworkAdapter WHERE Manufacturer != 'Microsoft' AND (ConfigManagerErrorCode = 0 OR (ConfigManagerErrorCode = 22 AND NetConnectionStatus = 0))");// Final solution with filtering on the Manufacturer and PNPDeviceID not starting with "ROOT\"// Physical devices have PNPDeviceID starting with "PCI\" or something else besides "ROOT\"mos = new ManagementObjectSearcher(@"SELECT * FROM Win32_NetworkAdapter WHERE Manufacturer != 'Microsoft' AND NOT PNPDeviceID LIKE 'ROOT\\%'");// Get the physical adapters and sort them by their index. // This is needed because they're not sorted by defaultIList<ManagementObject> managementObjectList = mos.Get() .Cast<ManagementObject>() .OrderBy(p => Convert.ToUInt32(p.Properties["Index"].Value)) .ToList();// Let's just show all the properties for all physical adapters.foreach (ManagementObject mo in managementObjectList){ foreach (PropertyData pd in mo.Properties) Console.WriteLine(pd.Name + ": " + (pd.Value ?? "N/A"));}   That's it. Hope this helps you in some way.

  • What is the syntax for Dsynchronize "exclude filter" for files 's full path to exclude bin\* and obj\* of a C# solution?

    - by Nam G. VU
    Dsynchronize is a great free tool to sync two folders. I'm using it to sync two solutions checked out from two different TFS Team Collection. I want to exclude the following: All files in bin folder All files in obj folder I tried bin\*; obj\* but it doesn't work. How can I do that? ps. Though, trying *.g.* and *cache* help to exclude the files whose names match with the filter. It seems the filter is applied to the file name only NOT the full path of the file

  • WebLogic Server 11g with java based node manager stdout/stderr log path configuration.

    - by Mircea Vutcovici
    Hi, How I can configure the path where the stdout logs are written by the WebLogic server? I've read about -Dweblogic.log.RedirectStdoutToServerLogEnabled=true, but this redirects only part of the output. For example if I will run a thread dump, the output will remain in the original log file. I think it should be an option in nodemanager/startup.properties file. WebLogic version is 10.3.2.0 and I am using a java based node manager. OS is RHEL 5. Thank you, Mircea

  • notation of Path to files/folders/drives that is shared on a network in windows?

    - by claws
    Hello, When some thing shared on network using windows network share option. Some people use path like \\something\something\something$ I'm don't know if this is correct way or not. but as far as I remember there is a dollar sign. Can any one please tell me. What is this notation? Where can I find more details about this? What is samba server/sharing? I don't understand when people use it. Is it something related to Linux? EDIT I'm a programmer. I guess this file sharing on network using windows uses client server architecture. I want to know what is this server on windows called? What protocol does it use? client is of course our windows explorer.exe? Which service in services.msc is responsible for this?

  • How do you change the "scan this dir for additional ini files" path?

    - by amvx
    I managed to get the custom INI to load, but its still loading other .ini files from the default location. I created an fcgi wrapper that passed the ini value as a parameter. That worked. Now just these other ini's need to be loaded from the same dir as my custom ini. The problem is the other .ini files are overriding the settings in my custom php.ini =/ I realize the problem now is that the php.fcgi was compiled with a custom path parameter. So that's a problem. I might have to recompile it using a different location or none at all. I'd hate to have to compile an fcgi for each domain =/

  • Is there a plugin for [Path] Finder to browse zip-archives as folders?

    - by Andrei
    Hi, I am migrating from Windows to OS X and looking for a good way to browse zip, rar etc. archives. Ideally, I need a plugin for Finder which will allow me to open archives as folders. Is there one, or any other suitable solution? Preferably free Update As I understand, most of Mac users are using Path Finder app for file management. It is an awesome program, however surprisingly it also doesn't have such functionality. I guess, the problem is in the way of thinking – my Windows-thinking is not applicable to Mac. Here are some threads for other former Windows users to push Cocoatech in a right direction: http://forum.cocoatech.com/showthread.php?t=2883 http://forum.cocoatech.com/showthread.php?t=5167

  • Unable to reach files in subfolder with domain name in path in IIS 5.

    - by Chuck Conway
    In IIS 5 files in the url: http://acme.com/_cache/cache-www.acme.com/v3.css are not accessible. All files below "cache-www.acme.com" are unreachable. I've verified that the files exists. Permissions are not a problem. I've assigned "Everyone" to the files and give "Everyone" full rights. What I have determined is in IIS 5 if there is a domain in the folder path, IIS 5 gets confused... Other javascript files outside the directory comedown fine... Any thoughts?

  • MS Excel: Can I link images using a relative path?

    - by Port Islander 2009
    I am working on an MS Excel document that contains a lot of (around 200) images. They are currently saved within the document, so the file becomes huge and working gets very slow. Linking the pictures without saving them works very well - I now have the Excel document and a folder "pictures" next to it that contains all my image files. However, when I move the document and the folder to a new location, all my pictures disappear. This seems to be because Excel saves the link information as absolute paths. (Update: Actually, according to this thread, Excel stores the link information as relative paths as well. Now I really don't know why my links break down..) Is there a convenient way to save them as relative paths or have Excel automatically update the path information? Update: It's important that the images get displayed on the sheet and can be printed. I am working with Microsoft Excel for Mac 2008 and 2011. I really appreciate your help.
