• Installing WinPcap on Windows 8

  - by Dave Robinson

  I know there has been lots of discussion already on installing WinPcap on Windows 8. I'm running the RTM version. I was able to install WinPcap without a hitch by using the Windows 7 compatibility mode. Since then, I've noticed that WinPcap has stopped running and is actually no longer even installed. I tried installing it again, but now it continues to tell me that WinPcap does not work with my version of Windows. Compatibility modes and admin privileges make no difference. The only thing I remember doing to my system was installed 900MBs of Windows Updates. Does anyone have any ideas about what I might do to get WinPcap installed? I've already ensured that the compatibility mode settings I changed were in effect for all users. I've already ensured that "run this program as an administrator" is checked on the compatibility tab for all users. I've also tried installing WinPcap 4.1.2 and 4.1.1. No success with either.

• Wrapper Classes for Backward compatibility in Java

  - by Casebash

  There is an interesting article here on maintaing backwards compatibility for Java. In the wrapper class section, I can't actually understand what the wrapper class accomplishes. In the following code from MyApp, WrapNewClass.checkAvailable() could be replaced by Class.forName("NewClass"). static { try { WrapNewClass.checkAvailable(); mNewClassAvailable = true; } catch (Throwable ex) { mNewClassAvailable = false; } } Consider when NewClass is unavailable. In the code where we use the wrapper (see below), all we have done is replace a class that doesn't exist, with one that exists, but which can't be compiled as it uses a class that doesn't exist. public void diddle() { if (mNewClassAvailable) { WrapNewClass.setGlobalDiv(4); WrapNewClass wnc = new WrapNewClass(40); System.out.println("newer API is available - " + wnc.doStuff(10)); }else { System.out.println("newer API not available"); } } Can anyone explain why this makes a difference? I assume it has something to do with how Java compiles code - which I don't know much about.

• How does "Compatability Mode" in Windows 7 affect the application?

  - by Robert C. Cartaino

  Background: Based on the answer given to this question: "Skype behaviour in the Windows 7 Superbar" ...you can get Skype to minimize to the system tray (rather than the task bar) by running it in compatibility mode. (red flags going off in my head) That's the behavior that I want but what does "compatibility mode" do to the executing application? I am concerned about changing the execution mode of an entire (important) application to a previous generation just to alter the user interface behavior a bit. So, what does compatibility mode actually do internally? What are the disadvantages, as in "how could the application (Skype) suffer?"

• Virtual machine image compatibility between VMware Server and VMware Player

  - by alexandrul

  I'm trying to minimize the number of different product versions used on my PC's both at work and at home. So far I have a mixture of: VMware Server 1.0.7 VMware Server 2.0.2 VMware Player 2.5.3 VMware Player 3.0.0 and I would love to upgrade each product family to the latest version. Since Virtual Machine Mobility Guide is marked as deprecated, can anyone point me to some fresh information about virtual machine compatibility between VMware Player and VMware Server, in order to still be able to move virtual machines back and forth between the mentioned products? Update What I'm looking for is an updated document with virtual machines hardware versions, and the VMware products that are able to use that specific hardware version, so I can know - given the products that are using a specific virtual machine - what is the maximum hardware version that I can update the virtual machine to.

• Microsoft Office Compability Pack "The converter failed to open the file" error & "This is a pre-release version"

  - by HaydnWVN

  What issues have people encountered with older OS's (2000, XP) and olders versions of Microsoft Office (2000, XP, 2003) with the 'Microsoft Office Compitibility Pack'? I have a couple of Windows 2000 client PC's encountering different errors when attempting to open .docx or .xlsx documents, some with Office XP and the others with Office 2003. Reading through forums it appears that the different versions of the compatibility pack, not all were compatible with Windows 2000 (versions 3 & 4 are not). There are also Service Packs for the Compatibility Pack. With these Windows 2000 clients, it seems i need the Compatibility Pack version 2, then to install the Service Packs, yet i'm unable to find a link for version 2 of it. First error message: "This is a pre-release version of the Compatibilty Pack and can open pre-release Office 2007 files only." Is solved below. Second error message: "The converter failed to open the file." Is still on going.

• Memory compatibility?

  - by nvillec

  I'm in the process of building a PC intended mostly for gaming and I've got a few questions. Currently, I only have the motherboard and CPU: Motherboard: GIGABYTE GA-Z68AP-D3 CPU: Intel Core i3-2120 My main question is about memory compatibility. I have 4 Hynix 2GB HMT125U7BFR8C-G7 with light-moderate use laying around and I'd love to save a few bucks if I can. I've read that this is server memory... a) Will that be a problem for PC use? b) Is it compatible with the motherboard? I've emailed Hynix and checked Crucial to no avail. If incompatible, what memory would be a good fit given the components I have? The motherboard has 4 sockets and supports up to 32GB, but I don't know that I have the budget for that at the moment. Thanks!!

• Dell Inspirion 1525 64bit driver compatibility

  - by Tony

  Hello, Can anyone tell me what the compatibility of drivers on 64bit vista are like on the Dell Inspiron 1525. Mine is just a year old now and I want to upgrade to 64bit vista. I wondered if there's known issues with drivers that I should be aware of before upgrading? Tony PS: is the upgrade worth it? My machine has 3GB of RAM and runs a T5800 2.0GHz DuoCore Processor. I use Visual Studio often and have loads of things open at the same time a lot. That's why I'm considering an upgrade.

• I think I disabled IE8's compatibility view

  - by malatio

  I have an install of IE8 that doesn't have the compatibility view button next to the url bar. I vaguely remember during install that there was a question about whether it was to be available or not, I may have clicked no. Or maybe that was a dream. There are no options that I can see about it being available or not. Anyone know how to enable it? I'm about to try re-install but I'm hoping I can fix it without re-installing. Version: 8.0.6001.18702 ; Update Versions: 0

• Implementing Database Settings Using Policy Based Management

  - by Ashish Kumar Mehta

  Introduction Database Administrators have always had a tough time to ensuring that all the SQL Servers administered by them are configured according to the policies and standards of organization. Using SQL Server’s  Policy Based Management feature DBAs can now manage one or more instances of SQL Server 2008 and check for policy compliance issues. In this article we will utilize Policy Based Management (aka Declarative Management Framework or DMF) feature of SQL Server to implement and verify database settings on all production databases. It is best practice to enforce the below settings on each Production database. However, it can be tedious to go through each database and then check whether the below database settings are implemented across databases. In this article I will explain it to you how to utilize the Policy Based Management Feature of SQL Server 2008 to create a policy to verify these settings on all databases and in cases of non-complaince how to bring them back into complaince. Database setting to enforce on each user database : Auto Close and Auto Shrink Properties of database set to False Auto Create Statistics and Auto Update Statistics set to True Compatibility Level of all the user database set as 100 Page Verify set as CHECKSUM Recovery Model of all user database set to Full Restrict Access set as MULTI_USER Configure a Policy to Verify Database Settings 1. Connect to SQL Server 2008 Instance using SQL Server Management Studio 2. In the Object Explorer, Click on Management > Policy Management and you will be able to see Policies, Conditions & Facets as child nodes 3. Right click Policies and then select New Policy…. from the drop down list as shown in the snippet below to open the  Create New Policy Popup window. 4. In the Create New Policy popup window you need to provide the name of the policy as “Implementing and Verify Database Settings for Production Databases” and then click the drop down list under Check Condition. As highlighted in the snippet below click on the New Condition… option to open up the Create New Condition window. 5. In the Create New Condition popup window you need to provide the name of the condition as “Verify and Change Database Settings”. In the Facet drop down list you need to choose the Facet as Database Options as shown in the snippet below. Under Expression you need to select Field value as @AutoClose and then choose Operator value as ‘ = ‘ and finally choose Value as False. Now that you have successfully added the first field you can now go ahead and add rest of the fields as shown in the snippet below. Once you have successfully added all the above shown fields of Database Options Facet, click OK to save the changes and to return to the parent Create New Policy – Implementing and Verify Database Settings for Production Database windows where you will see that the newly created condition “Verify and Change Database Settings” is selected by default. Continues…

• Compatibility between JBoss Cache to JBoss Server

  - by Spiderman

  Our application runs succesfully on Tomcat, Websphere and Weblogic and as part of it uses Jboss Cache version 3.1.0.G. Now we would like adjust our app to run also in Jboss server environment. Is there any Jboss server version that can co-exist working together with JBoss cache of this version (3.1)? I couldn't find a match in a compatibility matrix that Jboss publish here: http://www.jboss.org/jbosscache/compatibility.html Related issue (http://stackoverflow.com/questions/2849036/configure-jboss-cache-to-run-on-jboss-server-4-2-3-ga)

• How to activate Win XP from Windows 7 compatibility mode on MacOS Parallels 5

  - by Ben Hammond

  I am running Parallels Desktop 5.0.9344 for Mac. I am running Mac OS 10.6.3 10D2094 I have bought a retail copy of Window 7 professional specifically because I need the XP compatibility. Windows 7 is installed and working. I have problems with the XP activation Windows7 'Virtual PC' does not run under Parallels (strange error about Server Execution failed 0x80080005). I have used the Parallels Transporter to convert the "Windows XP Mode Base.vhd" file into a parallels Virtual Machine. This copy of XP now starts normally, however it records itself as unregistered. There was a KEY.txt file in the same directory as the .vhd file; although this file contains a valid-looking activation key, it does not appear to activate the instance of XP. I have also tried to enter the Win7 activation key; this does not work either. I have tried calling the two phone numbers; an automated system asked me to enter 56 digits through the telephone and then accused me of being a pirate. I believe it may be possible to install Win7 via Bootcamp, start WinXP under Virtual PC, activate it and then import this activated .vhd into Parallels; but that seems a long way round, and is far from certain. What can I do to get WinXP running under Mac Parallels Desktop ?

• Excel 2010 data validation warning (compatibility mode)

  - by Madmanguruman

  We have some legacy worksheets that were created in Excel 2003, which are used by LabVIEW-based test automation software. The current LabVIEW software can only handle the legacy .xls format, so we're forced to keep these worksheets as-is for the time being. We've migrated to Office 2010 and when working with these worksheets, I see this warning: "The following features in this workbook are not supported by earlier versions of Excel. These features may be lost or degraded when you save this workbook in the currently selected file format. Click Continue to save the workbook anyway. To keep all of your features, click Cancel and then save the file in one of the new file formats." "Significant loss of functionality" "One or more cells in this workbook contain data validation rules which refer to values on other worksheets. These data validation rules will not be saved." When I click 'Find', some cells that do indeed have validation rules are highlighted, but those rules are all on the same worksheet! We're using simple list-based validation, with some cells off to the side containing the valid values (for example, cell B4 has a List with Source "=$D$4:$E$4") This makes no sense to me whatsoever. One, the workbook was created in Excel 2003, so obviously we couldn't implement a feature that doesn't exist. Secondly, the modifications we're making don't involve changing the validation rules at all. Thirdly, the complaint that Excel is making is incorrect! All of the rules are on the same worksheet as the target. As if the story wasn't bizarre enough: I went ahead and saved the worksheet with Excel 2010. I then went to an old computer back in the lab and opened the document with Excel 2003. Guess what - the validations were untouched! My questions are: is this a legitimate bug in Excel 2010, or is this some exotic error in the legacy .xls worksheet that is confusing the heck out of Excel 2010? Has anyone else observed this issue working in compatibility mode?

• Office Compatibility Pack and File Permissions

  - by hymie

  MS isn't my thing, so I hope somebody can give me a pointer. We have a Windows domain, with a Server-2003-SP1-Enterprise file server. One of the specific files is a MS Excel 2007 (XLSX) file created by user LK. In the "Security" preferences setting, about a half-dozen users (including me) have access to this file. LK is the owner and has "full control", while the rest of us have "Read" , "Read & Execute", and "Write" permission. LK is also the owner of the directory that this file resides in. I don't know if that's relevant. So far so good. My desktop machine has Windows XP SP3 , and Excel 2003 SP3 , and the "Office Compatibility Pack" which lets me read and write the new XLSX files. However, whenever I write the file, the permissions are changed. The newly-written file only has permissions for LK and me, and both are "Full control" So in short, what am I doing wrong, and how should I set this up to do it right, keeping the permissions on the file that were there when I started?

• Speed vs security vs compatibility over methods to do string concatenation in Python

  - by Cawas

  Similar questions have been brought (good speed comparison there) on this same subject. Hopefully this question is different and updated to Python 2.6 and 3.0. So far I believe the faster and most compatible method (among different Python versions) is the plain simple + sign: text = "whatever" + " you " + SAY But I keep hearing and reading it's not secure and / or advisable. I'm not even sure how many methods are there to manipulate strings! I could count only about 4: There's interpolation and all its sub-options such as % and format and then there's the simple ones, join and +. Finally, the new approach to string formatting, which is with format, is certainly not good for backwards compatibility at same time making % not good for forward compatibility. But should it be used for every string manipulation, including every concatenation, whenever we restrict ourselves to 3.x only? Well, maybe this is more of a wiki than a question, but I do wish to have an answer on which is the proper usage of each string manipulation method. And which one could be generally used with each focus in mind (best all around for compatibility, for speed and for security). Thanks.

• Check for Block Ads/Scripts (Browser Addons, Compatibility)

  - by acidzombie24

  I'm conflicted. you guys decide if this should migrate to SU or not. I would like to test my site against popular browser ad ons. ATM i have tested against noscript and adblock plus for firefox. What other popular ad ons should i check compatibility with? By compatibility i mean to work as intent on browsers i support (opera, firefox, chrome, IE 7/8) which include ads. NoScript broke my site and for adblock plus i ask once per week to consider allowing ads. When i see IE6 i notify the user the site is known to be unusable with that browser (The site is script heavy by nature and i wouldnt want to accidentally serve ads to infect users of IE6 with a virus).

  I have the following python code: try: pr.update() except ConfigurationException as e: returnString=e.line+' '+e.errormsg This works under python 2.6, but the "as e" syntax fails under previous versions. How can I resolved this? Or in other words, how do I catch user-defined exceptions (and use their instance variables) under python 2.6. Thank you!

• Need a code snippet for backward paging...

  - by Ali

  Hi guys I'm in a bit on a fix here. I know how easy it is to build simple pagination links for dynamic pages whereby you can navigate between partial sets of records from sql queries. However the situation I have is as below: COnsider that I wish to paginate between records listed in a flat file - I have no problem with the retrieval and even the pagination assuming that the flat file is a csv file with the first field as an id and new reocrds on new lines. However I need to make a pagination system which paginates backwards i.e I want the LAST entry in the file to appear as the first as so forth. Since I don't have the power of sql to help me here I'm kinda stuck - all I have is a fixed sequence which needs to be paginated, also note that the id mentioned as first field is not necessarily numeric so forget about sorting by numerics here. I basically need a way to loop through the file but backwards and paginate it as such. How can I do that - I'm working in php - I just need the code to loop through and paginate i.e how to tell which is the offset and which is the current page etc.

• Iterating backward

  - by MBennett

  Suppose I have a vector<int> myvec and I want to loop through all of the elements in reverse. I can think of a few ways of doing this: for (vector<int>::iterator it = myvec.end() - 1; it >= myvec.begin(); --it) { // do stuff here } for (vector<int>::reverse_iterator rit = myvec.rbegin(); rit != myvec.rend(); ++rit) { // do stuff here } for (int i = myvec.size() - 1; i >= 0; --i) { // do stuff here } So my question is when should I use each? Is there a difference? I know that the first one is dangerous because if I pass in an empty vector, then myvec.end() - 1 is undefined, but are there any other hazards or inefficiencies with this?

• About the forward and backward a word behaviour in Emacs

  - by janoChen

  I don't know if there's something wrong with my settings but when I press M-f (forward a word) it doesn't matter where I am, it never place the cursor in the next word (just between words). This doesn't happen with M-b which place my cursor in the beginning of the previous word. Is this a normal behavior? How do I place my cursor at the beginning of the following word?

• Django: ordering by backward related field property

  - by Silver Light

  Hello! I have two models related one-to-many: a Post and a Comment: class Post(models.Model): title = models.CharField(max_length=200); content = models.TextField(); class Comment(models.Model): post = models.ForeignKey('Post'); body = models.TextField(); date_added = models.DateTimeField(); I want to get a list of posts, ordered by the date of the latest comment. If I would write a custom SQL query it would look like this: SELECT `posts`.`*`, MAX(`comments`.`date_added`) AS `date_of_lat_comment` FROM `posts`, `comments` WHERE `posts`.`id` = `comments`.`post_id` GROUP BY `posts`.`id` ORDER BY `date_of_lat_comment` DESC How can I do same thing using django ORM?

• jQuery prevAll displaying text in backward ordering

  - by SoulieBaby

  hi all, I'm trying to use jQuery to get all the paragraphs before the first h2 tag in my content. Here's the code I'm using: $(".content").find("h2:first").prevAll().text() Which is grabbing the content, although it's displaying it in backwards order. Example content: <div class="content"> <p>paragraph 1</p> <p>paragraph 2</p> <p>paragraph 3</p> <h2>First h2 tag</h2> <p>paragraph 4</p> <p>paragraph 5</p> <p>paragraph 6</p> <h2>Second h2 tag</h2> </div> The above code is outputting: <p>paragraph 3</p> <p>paragraph 2</p> <p>paragraph 1</p> Is there any way of reversing this, so it's in the correct order? I have tried using nextAll using different codes, but it seems to grab all of my content, or not work at all lol
