• (Possibly) Corrupted DDCrypt self-decrypting file

  - by sca

  I recently discovered some files I had encrypted and archived on a CD using DDCrypt 2.0, which is a small encryption utility from back in the day. One of its functions is to create self-decrypting files, which are essentially EXE files that you can enter a password and then have the file extracted onto your filesystem. Unfortunately, I can't seem to get them to do this properly. They appear to be decrypting and then at the last moment I get the error: Error opening encrypted file C:\users\username\Temp\dde3cfa.tmp Reason: Success and then another dialog immediately says Error extracting ddc file. I'm not really sure what this means (certainly not success), but I've checked out the temporary file and it appears to be garbage data (although of the right file size). I don't know if anyone has an idea what might be done here to extract the files, or has dealt with a similar situation before. Any ideas are appreciated! Thank you in advance for your time and any help you can provide.

• Duplicate of IPSEC certificate template not displaying

  - by Tim Brigham

  I am working on getting IPSEC working on computers outside my domain. I am unable to get a duplicate of the IPSec Offline Request template to show on the web interface. My CA is 2008 R2 Enterprise and the permissions on the template should be adequate to allow me access (my account has read and enroll). If I publish the original template it functions as desired. I also have other custom templates in use (although using autoenrollment). The duplicate is almost identical to the original, excepting that it has a longer validity period and the private key is marked as exportable. How do I debug at this point?

• How to set up an extended desktop on dual monitors in Kubuntu 9.04?

  - by Dennis

  I'm using my laptop (Lenovo Thinkpad T60) and I have a secondary monitor (which has a different resolution than my laptop screen) connected by VGA. Kubuntu recognizes the monitor and it functions but my desktop is mirrored (i.e. an identical copy) across the dual monitors (which is useless to me). How can I extend my desktop across both monitors? P.S. I googled it but the solutions I found weren't standard, they were hardware specific and you had to manually change system files, etc.. There must be an easier way. edit: Here is a snapshot of the settings.

• VBA: Parse preceding numbers from string

  - by buttonsrtoys

  I need to parse into two substrings a string that always starts with numeric text followed by alphnumeric text. The strings can vary a bit, but not too much. Below are examples of incoming format and the strings I need: "00 10 50 Information to Bidders" ==> "00 10 50", "Information to Bidders" "001050 Information to Bidders" ==> "001050", "Information to Bidders" "00 10 50 - Information to Bidders" ==> "00 10 50", "Information to Bidders" "001050 -- Information to Bidders" ==> "001050", "Information to Bidders" I was hoping it would only be a half dozen lines of VBA, but my code is turning into a loop where I'm testing every character in the string to see where the changeover from numeric-only to non-numeric, then parsing the string based on the changeover location. Not a big deal, but messier than I was hoping for. Are there VBA functions that would eliminate the need to iterate through each string character?

• EXCEL function working like SQL group by + count(distinct *)?

  - by Solo

  Suppose I have an EXCEL sheet with below data CODE (COL A) | VALUE (COL B) ============================== A01 | 10 A01 | 20 A01 | 30 A01 | 10 B01 | 30 B01 | 30 Is there an EXCEL function working like .. SELECT CODE, count (Distinct *) FROM TABLE GROUP BY CODE CODE | Distinct Count of Value =================================== A01 | 3 B01 | 1 or, better yet, Can we have an excel formula pasted in Column C to get something like this: CODE (COL A) | VALUE (COL B) | DISTINCT VALUE COUNT WITH MATCHING CODE (COL C) =============================================================================== A01 | 10 | 3 A01 | 20 | 3 A01 | 30 | 3 A01 | 10 | 3 B01 | 30 | 1 B01 | 30 | 1 I know I can use pivot table to get this result easily. However due to reporting requirements I have to append the "distinct count" column to the excel sheet, hence pivot table is not an option. My last resort is to use Excel Macro (Which is fine), but before that I would like to learn whether excel functions can accomplish this kind of task. Many thanks!

• Linux, PHP, and mysqlnd?

  - by bob-the-destroyer

  Looks like most common distros build their PHP packages without mysqlnd, instead relying on the old libmysql library. Are there any distros that do include the new mysql native driver even as an option in any of their officially supported repositories? If not, is it possible (and if so, how) to rebuild these three (mysql, mysqli, & pdo_mysql) extensions without having to rebuild the entire PHP install? In my case, there are several PHP functions I need that are available only if these Mysql extenstions are built against mysqlnd. So I'd be fine installing a new OS to get these if the OS offers and supports it.

• Getting the keyboard working on a MacBook under Windows XP x64

  - by Theran

  Despite Windows XP Professional x64's unsupported status on MacBooks (model A1181), I've managed to get most of the hardware working by manually installing either the drivers on the OS X Snow Leopard CD, or finding the appropriate drivers online. However, even after installing the Apple keyboard driver from the CD, I can't get Windows to actually use the special driver. Instead, the keyboard just shows up as a generic USB keyboard, with non-functioning Fn and other special keys. Being unable to generate a right-click or Ctrl-Alt-Del makes Windows a bit of a challenge to use. I've tried: uninstalling and reinstalling the keyboard driver removing the keyboard under device manager and letting Windows re-detect it using device manager to manually update the driver How do I get the special functions of the MacBook keyboard working under XP x64?

• Which particular file caused "Delayed write failed" error?

  - by user35020

  I sometimes get this error when resuming from hibernation: Delayed Write Failed: Windows was unable to save all the data for the file G:\$Mft. The data has been lost. This error may be caused by a failure of your computer hardware or network connection. Please try to save this file elsewhere. I know this is caused because the hard drive (G:, an external USB drive) was (a) plugged in when I hibernated and wasn't ready at wake-up, or (b) I simply forgot to plug it when resuming from hibernation. My question is: is there any way to see which particular file/folder/etc failed to be written? The hard drive functions correctly before and after, so there seems to be no permanent damage. Is there a detailed log someplace or a utility? I've searched but found nothing. Thanks for any help!

• Keyboard shortcut to cycle through programs (rather than just the alt-tab switch)?

  - by Steven Lu

  This question applies to both Windows and Mac OS X because I intend to use my mouse (Logitech G700) with both of them. The idea is I want one of my configurations to use two of my buttons to switch applications. However binding them to Alt/Cmd+Tab and Shift+Alt/Cmd+Tab is not good because the former functions as a toggle, and the latter cycles (in an unpredictable order). What I want is to move through my open applications in a circular buffer order. Do either of these OS's provide any keyboard shortcut that accomplishes this? I could live with just Alt/Cmd+Tab set to one button, but it limits me to being able to switch between only two programs.

• Can I get some help on a javascript project?

  - by HenryOrrin

  I'm learning javascript and I thought it would be fun to build a "simple" calculator. I spent a few hours coding, and implementing the functions, but it only works partially. Can one of you look at my code and try and figure out what's wrong? The Calculator.zip Here's some explanation of the issues: the add(), subtract(), multiply(), and divide() methods work partially, not at all, or don't do as they're supposed to.. sometimes the 0 wont clear when the replaceDisplay() method evaluates the screen. If it helps, I'm also using jquery, so keep that in mind. Thank you!

• Windows 8 will only recognize the Blu Ray ROM, if the install disk is present at boot time [migrated]

  - by aceinthehole

  If I have the install disk in the blu ray ROM drive at boot time and subsequently remove the disk and replace it with blu ray media everything functions as I'd expect. However, if I have no media present, or another disk in the drive at boot time, then windows 8 does not seem to recognize that the blu ray player is even present in the computer. It is not present in the 'my computer' screen, device manager does not show the player, and scanning for new hardware yields nothing. It seems that the driver is installed and working as expect, what is it about having the windows 8 install disk in the drive or not that would cause this kind of behavior?

• In mysql I want to set lower_case_table_names=1 on existing databases to avoid cases-sensitivity issues accross multiple platforms

  - by sakhunzai

  In mysql I want to set lower_case_table_names=1 on existing databases to avoid cases-sensitivity issues accross multiple platforms. A) What are the risks ?( besides show table issue) B) After setting lower_case_table_names=1, will I be in position to query databases across multiple platforms consistantly ? select * from USERS == select * from users; C) How the triggers + stored procedure + functions + views + events will be affected in this regards. I know lower_case_table_names is only for "TABLE" names but how about triggers other database objects . Will they remain case-insensitive How about views ? D) Do I need to rename all tables before/after this configuration setting or this will do the miracle in one step (i.e lower_case_table_names=1 neutralize table names) ? E) What will be the exact steps WRT:mysqd / my.ini ?

• Inconsistent slow DB connect times

  - by mcryan

  I have an app that shows significantly increased load times every 5 minutes. We use New Relic and I've been able to identify that every slow request is due to our DB connect functions. I've looked through our frontend servers and db servers and have ensured that there are no cronjobs running every 5 minutes - though the increase comes every 5 minutes without fail. I feel like I've tried everything I can to isolate this but I'm not having any luck. It is not coming from a cronjob, there is no cache expiring every 5 minutes, etc. What else could I check, and does anyone know of anything that could cause this sort of behavior? For what it's worth - our stack includes Apache, PHP, MySQL, Varnish and Memcache. SQL and memcache are running on dedicated servers and we have a number of frontend servers behind a load balancer, each running Apache and Varnish. Spike every 5 minutes: And it's always db connect (in red) taking up all of the time:

• Pressing zero key brings up lock/switch user screen in W7

  - by qinghua

  This issue started after my cat walked all over the keyboard... Whenever I press the "zero" key, the screen goes black and I'm taken to the lock/switch user screen. The other functions of the key work fine - it can produce ) and / like usual. Numlock is off, and as far as I know, my computer doesn't have Function Lock. If I log out of my user account and sign in as a guest, the "zero" works again, but if I create a new user profile, it doesn't work. I get the same issue when I hit "zero" using the on-screen keyboard. My keyboard layout is set to US English. I've uninstalled and reinstalled the ATK package, and updated my keyboard drivers. I have an ASUS U43JC-X1 laptop running Windows 7, and I haven't installed any new programs lately.

• Can one use Airport (Time Capsule) with an external DHCP server?

  - by DNS

  I currently share my DSL connection using a wireless router with DHCP disabled, and dnsmasq running on a Mac Mini serving DHCP & DNS. This setup is important because I have clients doing PXE boot, and I need the control over DHCP that dnsmasq provides. There is also a Time Capsule on the network that's used purely as a backup device; its wireless functions are disabled. The wireless router is starting to get a little flaky, and since it doesn't support 802.11n I'd like to replace it. Rather than buying a new router, I'd like to just use the Time Capsule. But I see no way to disable its DHCP server; when I set the connection type to PPPoE, it insists on serving DHCP. Is there any way to use Airport PPPoE with a DHCP server elsewhere on the network?

• How to redirect a specific url through a proxy for multiple services?

  - by CrystalFire

  I have a website hosted on 000webhost.com for free. I am unable to connect directly to the site because Comcast has blocked a portion of 000webhost's servers for free accounts due to other people hosting malicious content. In order to maintain my website, I cannot use my computer to directly connect to the server. I am wondering if there is a way by which I can specifically forward attempts to access the server through a proxy, transparently. The current system that I am on is Windows, but I also have systems running Mac OSX and Linux, so solutions for any system could be fine. I've found answers which work for http, but I'm looking for a solution which will let me use all the other functions as well, such as ftp and ssh.

• 2010 outlook stationery

  - by chris

  I have just installed Microsoft 2010 I am using the 'Outlook 2010' for my email program. For the past few years I have used Outlook Express and used the program quite well However with the Outlook 2010 I have not been able to find 2 functions that I was able to do on Outlook Express 1) OE I could press stationary and it would insert a BIT Map for me , however when I do stationary in Outlook 2010 it no longer allows me to insert the Bit map. 2) OE I created a rule that allowed me to copy emails into another folder , however in 2010 it only allows me to move as a rule and not the initial copy. Please could you explain how I may be able to use the same function in 2010?

• Mapping Ctrl+Arrow for Home/End/PageUp/Down

  - by user67275

  I'm using Windows 7 on Dell New Inspiron 14z Ultrabook. It doesn't have Home/End/PgUp/PgDn keys. Instead I have to use Fn + arrow keys. Can I re-map those to Ctrl + arrows or Alt + arrows or Shift + arrows? That way I could go one page up and down with only my right hands rather than with the left hand on the Fn key and right hand on arrow key. Also, volume up and down is assigned to FnF11 and FnF12. Can I re-map them to F11 and F12? Existing functions assigned to F11 and F12 will be replaced by FnF11 and FnF12. Is it possible?

• Role of OSI layers when we open a url in browser?

  - by user2715898

  I have searched on this topic a lot but I am not able to understand how and where OSI layers (Application, Presentation, Session, Transport, Network, Datalink, Physical) come into picture in the whole process of opening a webpage in browser. I have read this - http://stackoverflow.com/questions/2092527/what-happens-when-you-type-in-a-url-in-browser?lq=1 and I know all the functions of all the layers that are there in OSI model. Also, do we use OSI model or TCP/IP in the whole process? Basically I am having problem linking all the things together. And please forgive me if there are resources out there that explain this concept. You can definitely point to them.

• How is Javascript parsed/executed in a web browser exactly?

  - by ededed

  For example when I access web server likely Javascript will execute. From there on, how will the browser parse the Javascript, or "execute" the functions, the memory used, etc. How will the browser "handle" all of that? Does it act like a compilation lexer in that it passes line by line and generates object code, or does it use the DOM, and other specifications to handle memory, etc. Also, in terms of updating the page, and alterior concurrent executions as well, such as Flash, HTML, Java, etc. Point be simplified, how does the browser handle the scripts, the memory, and the logic on page from a javascript file?

• Adding a hyperlink in a client report definition file (RDLC)

  - by rajbk

  This post shows you how to add a hyperlink to your RDLC report. In a previous post, I showed you how to create an RDLC report. We have been given the requirement to the report we created earlier, the Northwind Product report, to add a column that will contain hyperlinks which are unique per row.  The URLs will be RESTful with the ProductID at the end. Clicking on the URL will take them to a website like so: http://localhost/products/3  where 3 is the primary key of the product row clicked on. To start off, open the RDLC and add a new column to the product table.   Add text to the header (Details) and row (Product Website). Right click on the row (not header) and select “TextBox properties” Select Action – Go to URL. You could hard code a URL here but what we need is a URL that changes based on the ProductID.   Click on the expression button (fx) The expression builder gives you access to several functions and constants including the fields in your dataset. See this reference for more details: Common Expressions for ReportViewer Reports. Add the following expression: = "http://localhost/products/" & Fields!ProductID.Value Click OK to exit the Expression Builder. The report will not render because hyperlinks are disabled by default in the ReportViewer control. To enable it, add the following in your page load event (where rvProducts is the ID of your ReportViewerControl): protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { rvProducts.LocalReport.EnableHyperlinks = true; } } We want our links to open in a new window so set the HyperLinkTarget property of the ReportViewer control to “_blank”   We are done adding hyperlinks to our report. Clicking on the links for each product pops open a new windows. The URL has the ProductID added at the end. Enjoy!

• Comments syntax for Idoc Script

  - by kyle.hatlestad

  Maybe this is widely known and I'm late to the party, but I just ran across the syntax for making comments in Idoc Script. It's been something I've been hoping to see for a long time. And it looks like it quietly snuck into the 10gR3 release. So for comments in Idoc Script, you simply [[% surround your comments in these symbols. %]] They can be on the same line or span multiple lines. If you look in the documentation, it still mentions making comments using the syntax. Well, that's certainly not an ideal approach. You're stuffing your comment into an actual variable, it's taking up memory, and you have to watch double-quotes in your comment. A perhaps better way in the old method is to start with my comments . Still not great, but now you're not assigning something to a variable and worrying about quotes. Unfortunately, this syntax only works in places that use the Idoc format. It can't be used in Idoc files that get indexed (.hcsp & .hcsf) and use the <!--$...--> format. For those, you'll need to continue using the older methods. While on the topic, I thought I would highlight a great plug-in to Notepad++ that Arnoud Koot here at Oracle wrote for Idoc Script. It does script highlighting as well as type-ahead/auto-completion for common variables, functions, and services. For some reason, I can never seem to remember if it's DOC_INFO_LATESTRELEASE or DOC_INFO_LATEST_RELEASE, so this certainly comes in handy. I've updated his plug-in to use this new comments syntax. You can download a copy of the plug-in here which includes installation instructions.

• SQL SERVER – Concat Function in SQL Server – SQL Concatenation

  - by pinaldave

  Earlier this week, I was delivering Advanced BI training on the subject of “SQL Server 2008 R2″. I had great time delivering the session. During the session, we talked about SQL Server 2010 Denali. Suddenly one of the attendees suggested his displeasure for the product. He said, even though, SQL Server is now in moving very fast and have proved many times a good enterprise solution, it does not have some basic functions. I naturally asked him for example and he suggested CONCAT() which exists in MySQL and Oracle. The answer is very simple – the equalent function in SQL Server to CONCAT() is ‘+’ (plus operator without quotes). Method 1: Concatenating two strings SELECT 'FirstName' + ' ' + 'LastName' AS FullName Method 2: Concatenating two Numbers SELECT CAST(1 AS VARCHAR(10)) + 'R' + CAST(2 AS VARCHAR(10)) Method 3: Concatenating values from table columns SELECT FirstName + ' ' + LastName FROM AdventureWorks.Person.Contact Well, this may look very simple but sometime it is very difficult to find the information for simple things only. Do you have any such example which you would like to share with community?

• OpenGL extension vs OpenGL core

  - by user209347

  I was doubting: I'm writing a cross-platform engine OpenGL C++, I figured out windows forces the developers to access OpenGL features above 1.1 through extensions. Now the thing is, on Linux, I know that I can directly access functions if the version supports it through glext.h and opengl version. The problem is that if on Linux, the core doesn't support it, is it possible there is an extensions that supports the same functionality, in my case vertex buffer objects? I'm doing something like this: Windows: (hashdeck) define glFunction functionpointer_to_the_extension (apparently the layout changes font size if I use #) Linux: Since glext already defined glFunction, I can write in client code glFunction, and compile it both on Windows AND Linux without changing a single line in my client code using the engine (my goal). Now the thing is, I saw a tutorial use only the extension on Linux, and not checking for the opengl implementation version. If the functionality is available in the core, is it also available as extension (VBO's e.g.)? Or is an extension something you never know is available? I want to write an engine that gets all the possibilities on hardware, so I need to check (on Linux) for extensions as well as core version for possible functionality implementation.
